feature Add file_fixture helper to syntax methods #1317
Conversation
|
The primary use case for this feature is for use with ActiveStorage-backed models. It doesn't currently work there, so I think we need some tests cases for that. I have a model with after(:build) do |instance|
instance.video.attach(
io: File.open(Rails.root.join('spec', 'fixtures', 'files', 'video.mp4')),
filename: 'video.mp4'
)
endor, using this Rack helper: video { Rack::Test::UploadedFile.new("spec/fixtures/files/video.mp4") }but I was unable to attach a video using the new method in this PR: video { file_fixture("spec/fixtures/files/video.mp4") }This didn't raise any error, but it silently failed to attach a video. I think it is fine if this works for just the ActiveStorage case for now. We can always extend it other use cases as they emerge. We may even decide to move this into factory_bot_rails if we want to make it clear it is only meant to work with Rails. That would allow us to be opinionated about expecting the fixture files to live in video { file_fixture_upload("video.mp4") }This would match the helper method used in the ActiveStorage test suite |

This should go on the definition proxy, since it only needs to be available inside the attribute block. Otherwise when people include these syntax methods into their test suite it will end up overwriting the original ActiveSupport file_fixture method.

Good idea, we don't want to overwrite the original ActiveSupport file_fixture method.
But we also need to be able to call file_fixture from transient attributes and callbacks...
Why: This is to add simple support to files on factories. This is the original [issue](#1282). What: It is a common behavior to interact with files when creating factories, and it is used heavily, as demonstrated with the many examples in the issue, this is a first draft and I would love to see more use-cases to add to the acceptance test. For the time being we have at least the base case added.

Bundler/OrderedGems: Gems should be sorted in an alphabetical order within their section of the Gemfile. Gem activestorage should appear before pry.
Style/StringLiterals: Prefer double-quoted strings unless you need single quotes to avoid extra backslashes for escaping.

- I am having a hard time on where to locate the method and have access to the method name and the instance so I can do something like: ```ruby file_loader = FileLoader.new() instance.send(method_name).attach( io: file_loader.io, filename: file_loader.filename ) ```
