Hi @andypike,
The thing I've been struggling most with is the combination of form objects + file uploads.
So a I'm trying to add a picture to a blog post with CarrierWave:
class PostForm < Rectify::Form
extend CarrierWave::Mount
mount_uploader :image, ImageUploader
attribute :image
end
This works well when instantiating the PostForm from the model, but becomes complicated when using from_params. So specifically when a validation fails, you render :edit again with PostForm initialized from_params. Now, you get the page again, but the image we just selected is gone.
This sort of thing can normally be fixed by saving a cached version of the image https://github.com/carrierwaveuploader/carrierwave#making-uploads-work-across-form-redisplays. But if our form is not valid, we never save anything to the model, so I guess this goes against the whole idea of form objects.
Also, since the form object can be from_params, you cannot rely on getting the actually file like f.object.image.url, since you're not submitting the actual file every time. So now I add attribute :image_url so I can show a link to it if the file is already uploaded.
I hope that made sense, do you have any experience with Rectify + file uploads?
