Question

I’m a bit confused.

This is the form_for in the Getting Started section of Paperclip’s Github repository:

<%= form_for @user, :url => users_path, :html => { :multipart => true } do |form| %>

This is the form_for that is generated with Devise:

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => { :method => :put }) do |f| %>

How should I modify it to get Paperclip working?

Answer 1

Just add :multipart => true to the :html parameter like so.

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => { :method => :put, :multipart => true  }) do |f| %>
