Rails - implementing ajax in partials causing an error: 'cannot find method render'

I am encountering an issue with my form partial located within a div that has the id "chapcomments". The form includes a submit button:

<%= f.submit "Post", remote: true %>

Within the correct view folder, I have a file named create.js.erb which contains the following code:

$('#chapcomments').html("<%=j render 'shared/chap_comment_complete' %>");

In the controller, I have a format block for the create action:

def create
  @chap_comment = current_user.chap_comments.build(chap_comment_params)

  respond_to do |format|
    if @chap_comment.save
      format.js
      format.html {redirect_to chapter_path(@chap_comment.chapter)}
    else
      format.html { render :new }
      format.json { render json: @chap_comment.errors, status: :unprocessable_entity }
    end
  end
end

However, despite implementing these steps, I am not observing the desired ajax behavior. Can anyone pinpoint where I might be making a mistake?

Answer №1

After shifting the JS to the correct js.erb file within the view, make sure to transfer the remote: true section from the submit tag to your form_for declaration. Failure to do so will result in the format.html response block being displayed instead of format.js.
