Allow fixtures YAML files to set the model class in the file itself #20574
Conversation
|
Using ERB within yaml to set metadata feels surprising. How about using a special key to set fixture metadata? _fixture:
model_class: User
david:
name: David |
|
@jeremy That is close to my first thought. IMO, it seems good. Should I update the RP? |
|
@repinel yes, please do. |

is it necessary to create new tables to test this feature? Can't we reuse some tables that already exist? We try to not add more global models for single test scenarios like this.

let's give the full path here: test/fixtures/accounts.yml.

I missed this one. I'll revert the line.

This implementation is based on the fact that model_class will be called before each, otherwise you'd get a fixture for _fixture. We should probably change it to behave consistently regardless of call order. Meaning that we have to treat the _fixture key special that it won't ever be part of rows.
This could look something like this (pseudocode):
def model_class
raw_content["_fixture"]
# ...
end
def rows
raw_content.except "_fixture"
end
def raw_content
# read yaml-file and cache contents
end
Currently, `set_fixture_class` is only available using the `TestFixtures` concern and it is ignored for `rake db:fixtures:load`. Using the correct model class, it is possible for the fixture load to also load the associations from the YAML files (e.g., `:belongs_to` and `:has_many`).
