🧹 Outside diff range and nitpick comments (7)
contracts/database/migration/grammar.go (1)

10-11: LGTM: New method signature for changing columns. Minor suggestion for comment.

The CompileChange method signature is a valuable addition to the Grammar interface. It aligns with the PR objective of modifying the avatar field to be nullable and provides a clear way to compile SQL statements for changing column properties.

Consider slightly modifying the comment to be more specific:

- // CompileChange Compile a change column command into a series of SQL statements.
+ // CompileChange Compile a change column command into a string containing SQL statement(s).

This change more accurately reflects that the method returns a single string, which may contain one or more SQL statements.

database/migration/column.go (1)

82-86: LGTM: Nullable() method implementation is correct.

The Nullable() method is implemented correctly. It sets the nullable field to true, which aligns with the PR objective of making the avatar field nullable. The implementation is consistent with other methods in the struct and allows for method chaining.

For consistency with other methods in the struct, consider using r instead of migration.ColumnDefinition as the return type:

-func (r *ColumnDefinition) Nullable() migration.ColumnDefinition {
+func (r *ColumnDefinition) Nullable() *ColumnDefinition {
   r.nullable = convert.Pointer(true)
   return r
 }

This change maintains the ability to chain methods while being more specific about the return type.

database/migration/grammars/utils_test.go (2)

67-70: Approve the addition of TestPrefixArray with suggestions for improvement.

The new test function TestPrefixArray is a good addition to cover the prefixArray utility. However, consider enhancing the test coverage with the following suggestions:

  1. Add test cases for edge cases, such as:
    • Empty prefix
    • Empty input slice
    • Slice with empty strings
  2. Include a test case with a longer prefix and more diverse string inputs.
  3. Consider using a table-driven test approach for better readability and easier addition of test cases.

Here's an example of how you could improve the test using a table-driven approach:

func TestPrefixArray(t *testing.T) {
	testCases := []struct {
		name     string
		prefix   string
		input    []string
		expected []string
	}{
		{
			name:     "Basic case",
			prefix:   "prefix",
			input:    []string{"a", "b", "c"},
			expected: []string{"prefix a", "prefix b", "prefix c"},
		},
		{
			name:     "Empty prefix",
			prefix:   "",
			input:    []string{"a", "b", "c"},
			expected: []string{"a", "b", "c"},
		},
		{
			name:     "Empty input slice",
			prefix:   "prefix",
			input:    []string{},
			expected: []string{},
		},
		{
			name:     "Slice with empty strings",
			prefix:   "prefix",
			input:    []string{"", "b", ""},
			expected: []string{"prefix ", "prefix b", "prefix "},
		},
		{
			name:     "Longer prefix and diverse inputs",
			prefix:   "test_prefix_",
			input:    []string{"hello", "world!", "123"},
			expected: []string{"test_prefix_hello", "test_prefix_world!", "test_prefix_123"},
		},
	}

	for _, tc := range testCases {
		t.Run(tc.name, func(t *testing.T) {
			assert.Equal(t, tc.expected, prefixArray(tc.prefix, tc.input))
		})
	}
}

This approach allows for easier addition of test cases and improved readability.


Line range hint 1-70: Consider improving overall test file organization.

The addition of TestPrefixArray is consistent with the existing test structure. However, as the number of utility functions and their tests grow, consider the following suggestions to improve the overall organization of the test file:

  1. Group related tests together. For example, you could group all string manipulation utility tests (like TestPrefixArray) in one section.
  2. Add clear separation between different groups of tests, possibly with comments indicating the group of utilities being tested.
  3. Consider splitting the test file into multiple files if it becomes too large, with each file focusing on a specific group of related utilities.

Here's an example of how you could structure the file with grouped tests:

package grammars

import (
	// ... (imports)
)

// Column and Type related tests
func TestGetColumns(t *testing.T) {
	// ... (existing test code)
}

func TestGetType(t *testing.T) {
	// ... (existing test code)
}

// Value manipulation tests
func TestGetDefaultValue(t *testing.T) {
	// ... (existing test code)
}

// String manipulation tests
func TestPrefixArray(t *testing.T) {
	// ... (new test code)
}

// Add more groups as needed

This structure makes it easier to navigate and maintain the test file as it grows.

database/migration/schema.go (2)

99-105: Enhance test coverage and documentation for the new Table method.

While the Table method is well-implemented and consistent with the existing codebase, consider the following enhancements:

  1. Add unit tests specifically for this new method to ensure it behaves correctly under various scenarios.

  2. Update the package documentation to include information about this new method and its usage.

  3. Consider adding examples in the documentation to demonstrate how to use this method for common table modification scenarios.

Would you like assistance in generating unit tests or documentation for this new method?


99-105: New Table method aligns well with PR objectives and enhances Schema functionality.

The addition of the Table method to the Schema struct is a valuable enhancement that directly supports the PR objectives of modifying the users table to add and alter the avatar field. This method provides a flexible and reusable way to perform table modifications, which will be beneficial for future migration needs as well.

The implementation is consistent with the existing codebase structure and uses established helper methods, ensuring good integration with the current system.

Consider documenting this new capability in the project's migration guide or README to inform other developers about this powerful new feature for database schema modifications.

database/migration/schema_test.go (1)

64-129: Good addition, but consider aligning more closely with PR objectives

The new TestTable method is a valuable addition to the test suite, providing coverage for basic table creation and existence verification. The structure is consistent with existing tests, which is great for maintainability.

However, to more closely align with the PR objectives:

  1. Consider adding specific tests for the avatar field in the users table.
  2. Include a test case for modifying a column to be nullable, as per the second PR objective.

Here's a suggestion to add these specific tests:

err := schema.Create("users", func(table migration.Blueprint) {
    table.String("avatar")
})
s.NoError(err)
s.True(schema.HasColumn("users", "avatar"))

err = schema.Table("users", func(table migration.Blueprint) {
    table.String("avatar").Nullable().Change()
})
s.NoError(err)
// Add an assertion to verify the column is nullable

Additionally, the extensive commented-out code (lines 82-126) suggests plans for more comprehensive testing. While it's good to plan ahead, consider moving these commented sections to a separate "TODO" comment or issue to keep the current test method concise and focused.

🔇 Additional comments (17)
contracts/database/migration/column.go (3)

6-7: LGTM: Addition of Change() method

The Change() method is a good addition to the ColumnDefinition interface. It aligns with the PR objectives of modifying existing columns, specifically the avatar field in this case.


22-23: LGTM: Addition of Nullable() ColumnDefinition method

The Nullable() ColumnDefinition method is a valuable addition to the ColumnDefinition interface. It aligns with the PR objectives of making columns nullable, specifically the avatar field in this case. The method signature allows for method chaining, which is consistent with other methods in the interface.


Line range hint 1-26: Summary: Changes align well with PR objectives

The additions to the ColumnDefinition interface (Change() and Nullable() ColumnDefinition) are well-implemented and directly support the PR objectives of adding an avatar field to the users table and making it nullable. These changes provide the necessary functionality for the migrations mentioned in the PR summary.

The modifications are minimal, focused, and maintain the existing style and structure of the interface. Good job on keeping the changes concise and targeted!

contracts/database/migration/grammar.go (1)

8-9: LGTM: New method signature for adding columns.

The CompileAdd method signature is a good addition to the Grammar interface. It aligns with the PR objective of adding the avatar field to the users table and provides a clear way to compile SQL statements for adding new columns.

contracts/database/migration/blueprint.go (2)

16-17: LGTM! The new method aligns well with the PR objectives.

The addition of the GetChangedColumns() method to the Blueprint interface is a logical enhancement that complements the existing GetAddedColumns() method. This change directly supports the PR's objective of modifying the avatar field in the users table by providing a way to retrieve and potentially manage changed columns during migrations.

The method signature is consistent with the existing interface style, returning a slice of ColumnDefinition, which maintains code coherence and usability.


16-17: Verify the implementation and usage of the new method.

While the interface change looks good, it's crucial to ensure that the GetChangedColumns() method is properly implemented in the concrete types that implement the Blueprint interface, and that it's utilized correctly in the migration logic for modifying the avatar field.

To verify the implementation and usage, please run the following script:

This script will help us confirm that the new method is not only declared but also implemented and used correctly in the context of the avatar field modification.

database/migration/grammars/utils.go (2)

59-66: Overall assessment of changes to utils.go

The addition of the prefixArray function appears to be a supporting change for the larger PR objective. While the function itself is implemented correctly, its specific role in adding the avatar field to the users table is not immediately clear from this file alone.

The changes to this file are approved, pending clarification on how this utility function will be used in the context of the PR's main objective. Once that's clear, we can better assess if any further modifications or optimizations to the function are needed.


60-66: 🛠️ Refactor suggestion

Consider improving the prefixArray function for robustness and flexibility.

The prefixArray function is simple and efficient, but there are a few points to consider:

  1. The function modifies the input slice in-place, which might be unexpected for callers. Consider creating a new slice instead.
  2. There's no handling for empty input slices or empty prefixes.
  3. The function always adds a space after the prefix, which might not always be desired.

Here's a suggested improvement:

func prefixArray(prefix string, values []string) []string {
    if len(values) == 0 || prefix == "" {
        return values
    }
    result := make([]string, len(values))
    for i, value := range values {
        result[i] = prefix + value
    }
    return result
}

This version:

  • Creates a new slice, avoiding unexpected modifications to the input.
  • Handles empty input cases.
  • Doesn't add a space automatically, allowing more flexible usage.

If you prefer to keep the space, you could modify the concatenation to prefix + " " + value.

To understand how this function might be used in the context of database migrations, let's search for potential usage:

#!/bin/bash
# Search for potential usage of prefixArray in migration-related files
rg --type go -g '*migration*.go' "prefixArray"

This will help us verify if the function is being used as intended in the migration context.

database/migration/column.go (2)

26-28: LGTM: Change() method implementation is correct.

The Change() method is implemented correctly. It sets the change field to true, which aligns with the PR objective of modifying the avatar field. The implementation is consistent with other methods in the struct.


Line range hint 1-87: Overall assessment: Changes are well-implemented and align with PR objectives.

The additions of the Change() and Nullable() methods to the ColumnDefinition struct are well-implemented and directly address the PR objectives. These changes provide the necessary functionality to modify the avatar field in the users table as described in the PR summary.

The implementations are consistent with the existing codebase style and patterns, making them easy to understand and maintain. No other parts of the file were modified, keeping the changes focused and minimal.

database/migration/grammars/utils_test.go (1)

Line range hint 1-70: Summary of review and next steps

The addition of TestPrefixArray is a positive step towards improving test coverage for the utility functions in the grammars package. However, there are opportunities for further enhancement:

  1. Expand the test cases for TestPrefixArray to cover more scenarios and edge cases.
  2. Consider adopting a table-driven test approach for better readability and maintainability.
  3. Improve the overall organization of the test file by grouping related tests and adding clear separations between different utility function groups.

These improvements will contribute to a more robust and maintainable test suite for the grammars package.

To ensure that the prefixArray function is properly implemented and used within the codebase, please run the following verification script:

This script will help identify the implementation of the prefixArray function and its usage across the codebase, ensuring that the new test is testing a real and used function.

82-126: Address the commented-out code for future enhancements.

The commented-out section (lines 82-126) contains valuable test cases for column operations and detailed column attribute verification. This code suggests important functionality that should be tested but is currently not implemented.

Consider the following approaches:

  1. If the functionality for these tests is already implemented but not yet tested:

    • Uncomment and implement these tests as part of this PR.
    • If this expands the scope of the PR too much, create a separate issue to track the implementation of these tests.
  2. If the functionality for these tests is not yet implemented:

    • Remove the commented-out code from this file to keep the codebase clean.
    • Create separate issues to track the implementation of each major feature (e.g., column modification, detailed column attribute verification).
    • Add TODO comments with issue numbers instead of keeping the full code commented out.
  3. If you decide to keep the commented-out code:

    • Add a comment explaining why it's commented out and when it's expected to be implemented.
    • Ensure that there's a tracking issue for implementing these tests.

Would you like me to create a GitHub issue to track the implementation of these additional tests?

database/migration/blueprint.go (1)

Line range hint 193-206: LGTM with a suggestion: Consider adjusting the order of operations in addImpliedCommands.

The changes correctly implement the logic for adding implied commands for added and changed columns. However, consider moving the addAttributeCommands(grammar) call before prepending the new commands. This ensures that any attribute commands (like comments) are properly ordered with respect to the add and change commands.

Here's a suggested modification:

func (r *Blueprint) addImpliedCommands(grammar migration.Grammar) {
	r.addAttributeCommands(grammar)

	var commands []*migration.Command
	if len(r.GetAddedColumns()) > 0 && !r.isCreate() {
		commands = append(commands, &migration.Command{
			Name: commandAdd,
		})
	}
	if len(r.GetChangedColumns()) > 0 && !r.isCreate() {
		commands = append(commands, &migration.Command{
			Name: commandChange,
		})
	}
	if len(commands) > 0 {
		r.commands = append(commands, r.commands...)
	}
}

This change ensures that attribute commands are processed before add and change commands are prepended.

25-88: LGTM: Comprehensive TestCompileChange method added

The new TestCompileChange method is a valuable addition to the test suite. It uses table-driven tests to cover various scenarios for compiling changes to the database schema, which is a good practice for maintainability and extensibility.

One minor suggestion for improvement:

Consider adding a test case for a scenario where GetAutoIncrement() returns true for one of the columns. This would ensure that the auto-increment logic is properly tested in the context of changes.

64-129: Summary of changes and alignment with PR objectives

The addition of the TestTable method in database/migration/schema_test.go is a step in the right direction for improving test coverage of the schema functionality. However, it's important to note that the current implementation and the PR objectives seem to be misaligned:

  1. The PR objective mentions adding an avatar field to the users table, but the new test method creates a changes table with a name column.
  2. The PR objective also mentions making the avatar field nullable, but the current test doesn't cover column modification or nullability.

To address this misalignment, consider the following:

  1. Modify the TestTable method to create a users table instead of a changes table.
  2. Add a test case for adding an avatar column to the users table.
  3. Include a test case for modifying the avatar column to be nullable.

Here's a script to verify if these changes are present in the codebase:

#!/bin/bash
# Description: Verify if the test file includes tests for the 'users' table and 'avatar' column

# Test: Check for 'users' table creation
rg --type go 'schema.Create\("users"' database/migration/schema_test.go

# Test: Check for 'avatar' column addition
rg --type go 'table.String\("avatar"\)' database/migration/schema_test.go

# Test: Check for 'avatar' column modification to nullable
rg --type go 'table.String\("avatar"\).Nullable\(\).Change\(\)' database/migration/schema_test.go

This script will help ensure that the test file includes the necessary changes to align with the PR objectives.

Would you like assistance in modifying the TestTable method to better align with the PR objectives?

database/migration/blueprint.go (3)

Line range hint 8-9: LGTM: New constants for command types.

The addition of commandAdd and commandChange constants is consistent with the existing naming convention and aligns with the PR objectives of adding and changing columns.


151-154: LGTM: Updated ToSql method to handle new command types.

The addition of cases for commandAdd and commandChange in the ToSql method is consistent with the existing structure and correctly handles the new command types. This implementation aligns with the PR objectives of supporting the addition and modification of columns.


Line range hint 1-231: Summary: Changes look good overall, with a minor suggestion for improvement.

The modifications to database/migration/blueprint.go successfully implement support for adding and changing columns, aligning well with the PR objectives. The code is consistent with the existing structure and naming conventions. A minor suggestion was made to adjust the order of operations in the addImpliedCommands method, but this is not a blocking issue.

Given the overall quality of the changes and their alignment with the PR objectives, I recommend approving this PR once the suggested improvement has been considered.

22-23: LGTM: Simplified SetupTest method

The change to use NewPostgres() in the SetupTest method is a good improvement. It simplifies the setup process and likely ensures proper initialization of the Postgres struct.


93-137: LGTM: Enhanced TestCompileCreate method

The additions to mockColumn2 expectations and the updated expected SQL output improve the comprehensiveness of the TestCompileCreate method. These changes ensure that the test covers the handling of nullable columns correctly.

Regarding the past review comment about numeric default values:

The issue with numeric default values being enclosed in quotes in SQL statements is still present in the TestCompileChange method (line 72). This should be addressed to ensure correct SQL generation for numeric defaults.


Line range hint 1-137: Overall assessment: Good improvements with a minor issue to address

The changes to this file significantly enhance the test coverage for the PostgreSQL grammar implementation. The new TestCompileChange method and the improvements to TestCompileCreate make the test suite more comprehensive and robust.

Next steps:

  1. Address the issue with numeric default values being enclosed in quotes in SQL statements (line 72 in TestCompileChange).
  2. Consider adding a test case for auto-increment columns in the TestCompileChange method.

Once these minor adjustments are made, the changes will be ready for approval.

To ensure that the numeric default value issue is isolated to the test file and not present in the actual implementation, please run the following script:

✅ Verification successful

Numeric default values are correctly handled in SQL generation.

No instances of numeric default values being incorrectly quoted were found in the codebase.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check for potential mishandling of numeric default values in SQL generation

# Test: Search for instances where numeric values might be incorrectly quoted in SQL generation
rg --type go 'set default .(\d+).' -g '!*_test.go'

Length of output: 52


Script:

#!/bin/bash
# Description: Re-verify potential mishandling of numeric default values in SQL generation with enhanced regex

# Test: Search for instances where numeric values are incorrectly quoted in SQL generation
rg --type go "set default '(\d+)'" -g '!*_test.go'

Length of output: 58
