ActiveStorage validations

[Tobias Sandelius]

I can't find any docs about attachment validations. Are there any? If not, will it be added?

Given that the Rails guide

http://guides.rubyonrails.org/form_helpers.html#uploading-files

references external (non-rails) gems for managing uploaded files
I'd guess the answer to both those is no :-)

Seems like a worthwhile gem idea, though.

The new ActiveStorage framework in Rails 5.2 provide just that, I just cant find anything about validating them.

[Carlos Ramirez]

The initial release of Active Storage (as part of Rails 5.2) did not include the ability to validate attachments. 

Validations are intended to be a part of the Rails 6 release. Work to support this has already begun. 

In the meantime, if you need validations for Active Storage attachments right now, you can roll your own using custom validators. I have written a few blog posts on the subject that you might find helpful:

• Adding an Attachment Validator to Active Storage
  
• Validating the Content-Type of Active Storage Attachments
  

Hope that helps!
