Rails: set file to file_field

Question

Having the following form:

= form_for company, html: { multipart: true } do |form|
    = form.label :logo, 'Upload Image'
    = form.file_field :logo

I want to set file_field value to another user uploaded image (have the object of ActionDispatch::Http::UploadedFile class). Is there a way to do it?

Answer 1

You cannot set the value for the file field and its because of security.

e.g would you want websites on the internet to be able to automatically set a value of C:/some_secret_folder/password.txt to a file field and submit the form through JS ?
