Validate file type on Direct Uploads with Active Storage? Is it possible?

Question

I created a method in my model to validate the upload file type. But it won't work, and I assume it's because i am using Direct uploads.

Is it possible to validate the file type with direct uploads with active storage? and How can I?

I tried:

Model:

validate :correct_video_type


  def correct_video_type
    if video.attached? && video.content_type.in?(%w(video/mov video/mp4 video/avi video/mpeg))
      errors.add(:video, "Must be video format")
    elsif video.attached? == false
      errors.add(:video, "Video must be attached")
    end
  end

View:

<%= form.file_field :video, class: "upload", direct_upload: true %>

And nothing becomes validated...

I also tried front end validation, but this didn't work:

 <%= form.file_field :video, class: "upload", direct_upload: true, accept: 'video/mov, video/mpeg, video/mp4, video/avi' %>

None of these worked. Even if the front-end were to work, i would still want to validate it further on the backend.

How can I validate this?

Did you try adding a breakpoint in `correct_video_type` to see if it's called? — max pleaner, Apr 10 '19 at 23:42
I haven't. I also attempted this without using direct_upload and it also didn't work. I can assume its not being called? — uno, Apr 11 '19 at 00:24
