Question

I know, the current already asked, but I can not fix it…

Gemfile

 gem 'rails', '3.2.9'
 gem 'jquery-rails' , '2.0.2'

class RelationshipsController < ApplicationController

  def create
    @user = User.find(params[:relationship][:followed_id])
    current_user.follow!(@user)
    respond_to do |format|
      format.html { redirect_to @user }
      format.js
    end
  end

create.js.erb

  $("#follow_form").html("<%= escape_javascript(render('shared/unfollow')) %>")

I have partial \app\views\shared\_unfollow.html.erb

 <%= form_for current_user.relationships.find_by_followed_id(@account), 
        :html => { :method => :delete }, :remote => true do |f|%>
     <div class="actions"><%= f.submit 'unfollow' %></div>
 <% end %>

if press the button, the state does not change. Try add “.html_safe” doesn’t work too.

But if I do

$("#follow_form").html("bla bla bla")

or

$("#follow_form").html("<%= 10+10 %>")

it’s work

Answer 1

Try to change

$("#follow_form").html("<%= escape_javascript(render('shared/unfollow')) %>")

to

$("#follow_form").html('<%= escape_javascript(render("shared/unfollow")) %>');

Errors may be caused by invalid syntax of the javascript, so your javascript will not be executed. You will not see the erorrs in any browsers. But you can used Firefox to see the Ajax response.

I faced the similar problem before
