Get Paperclip file before save
Is it possible to read the file, in my case image file, inside Paperclip::Attachment before the file is saved?
I need to send the image to an api first and then from the response it's given if it is accepted the model and the image will be saved. Otherwise do nothing.
That's a fun one. I would imagine you could build a validation for this that would do what you want.
Some pseudo code for you:
class Model has_attached_file :attachment validates :attachment_against_api def attachment_against_api response = API.send(attachment) errors.add(:attachment, response.message) if response.failure end end
Turns out it is as easy as this
I tried this piece of code yesterday but didn't work and only gave me nil. The cause is I write that code before
model.attachment is assgined 😅
