I would update the version of granite you're using in your project to your forked branch. I.e.

granite:
  github: sardaukar/granite
  branch: add-group_by-to-builder-methods

Then see if everything works.

If everything works now, add a spec to https://github.com/amberframework/granite/blob/master/spec/granite/querying/query_builder_spec.cr.

I imagine the output of using .group_by is like Hash(String, T)? If so creating three records, two with the same name, and another that is diff, then using group_by to ensure the value of the one has 2 and the value of the other has 1.

Closing this PR due to shards error:

Failed git tag --list --contains add-group_by-to-builder-methods --column=never (malformed object name add-group_by-to-builder-methods). Maybe a commit, branch or file doesn't exist?

Gonna try with a shorter name...?

@Blacksmoke16 I don't get it 🤷

Changed the branch name to add-group-by and finally dev to get rid of hyphens but still getting:

Failed git tag --list --contains dev --column=never (malformed object name dev). Maybe a commit, branch or file doesn't exist?

when I run shards. Any thoughts? I even added a tag to my repo with the name dev but still same error.

I'm not sure I follow. What exactly are you doing?

Really, assuming you forked Granite, you just need to do like:

dependencies:
  granite:
    github: sardaukar/granite
    branch: add-group-by

You don't need to tag anything, just update the github reference and branch in your shard.yml to point to your repo/branch.

EDIT: Be sure you also update your repo to your own, as of course that branch doesn't exist in this repo.

I'm doing just that, but I get that error message from shards

Are you sure? I don't suppose you can share your shard.yml of your project where you're trying to test with this branch?
