add: ActiveRecord::QueryMethods::WhereChain#missing

[rhiroe]

Added ActiveRecord::QueryMethods::WhereChain#missing in version 6.1 or later.

Fixed to return ::ActiveRecord::QueryMethods::WhereChain when the where method has no argument.

I confirmed that no errors occurred when used with rbs-rails.

This Relation is ::ActiveRecord::Relation.
So, the model information is missing.
Aren't you trying to get the model information from here?

How about like this?

module QueryMethods
  class WhereChain[Relation]
    def missing: (*Symbol associations) -> Relation
  end
end

[rhiroe]

I will try it.

[ksss]

Almost good 👍
Can you add testing code for missing?

[rhiroe]

If we mimic the RBS generated by rbs-rails, we can write it like this...

class User < ActiveRecord::Base
  extend _ActiveRecord_Relation_ClassMethods[User, ActiveRecord_Relation, Integer]

  class ActiveRecord_Relation < ::ActiveRecord::Relation
    include _ActiveRecord_Relation[User, Integer]
    include Enumerable[User]
  end

  class ActiveRecord_Associations_CollectionProxy < ::ActiveRecord::Associations::CollectionProxy
    include _ActiveRecord_Relation[User, Integer]
  end
end

Include or extend _ActiveRecord_Relation_ClassMethods and _ActiveRecord_Relation causes a large number of MethodDefinitionMissing errors.

So I include or extend::ActiveRecord::Base::ClassMethods and ::ActiveRecord::Relation::Methods instead.

It looks like it was designed for that purpose.

It is enough to show that missing is associated with some type, even if the code is not executable.
I do not mind if there is no code that mimics rbs_rails.

[rhiroe]

@ksss Sorry, I have a question.
Is it that I am not getting Approve from you because the current test is not sufficient?

[ksss]

Yes. It seems to me that there is an increase in excessively managed test code.

The test code I had in mind is as follows:

User.where.missing.to_sql

[rhiroe]

I see. Thank you for your answer and example.
