Allow variants on file field

[Paul-Bob]

Feature

From here

File field should allow variants, maybe like:

field :profile_pic, as: :file, format_using: -> {
  value.variant(resize_to_limit: [480, 480])
}

[adrianthedev]

You can add .processed at the end.

field :profile_pic, as: :file, format_using: -> {
  value.variant(resize_to_limit: [480, 480]).processed
}

@Paul-Bob please write to the OP and add a guide in the docs with a link from the field field.

Close this issue when you see fit.

Thanks!

format_using: -> {
    value.variant(resize_to_limit: [28, 28]).processed.image
  }

This don't break the app but the image keeps original dimensions only with lower resolution, I think the expected output of a variation is to resize the image

The user want to be able to resize the image on the show view using variants not to keep the same size with different resolution.

field :cover_photo, as: :file, is_image: true

field :cover_photo, as: :file, is_image: true, format_using: -> { value.variant(resize_to_limit: [100, 100]).processed.image }
Result:

Expected:

I see that from previous messages and by the title of the issue it was not clear enough, originally the scope of the issue was to permit variants, than we noticed that variants can be applied followed by .processed.image but the result is different from the expectation.

It would be great if this would be added to the documentation.

[Paul-Bob]

Yes @WvanLelyveld this should be documented
