How do i post a form in rails using ajax?

Question

I have a rails app that I need to use Ajax to post on my model.

I have only this line in my filename.js.erb

$('#new-band a').html('<%= j render 'form'%>')

Here is my error:

Showing /<snip>/ajax/app/views/layouts/application.html.erb where line #8 raised:

undefined method `render' for #<#<Class:0x00007fad63eb3b98>:0x00007fad5e2c13f8>

I don't think this is the answer but try adding parens: j(render('form')) to be sure it is being parsed as intended by Ruby. — Kris

Where is filename.js.erb being called? can you add the controller ? — R. Sierra

Try changing your single quote to double quotes around the form. For example:

$('#new-band a').html('<%= j render 'form'%>')

Changes to:

$('#new-band a').html('<%= j render "form" %>')

You can try this:

$('#new-band a').html("<%= j render(:partial => 'form') %>");
