Remote: True Option Is Not Working With File Field In Rails 4

I am trying to submit form via ajax using remote:true option which contains input fields as well as file fields (need to upload images) Here is my view = form_tag('/campaigns/uplo

Solution 1:

remote: true does not work with multipart/file upload.

You can use remotipart gem for this.

Solution 2:

You're using form_tag instead of form_for. So, use file_field_tag instead of file_field.
