Gettin 500 Internal Server Error in rails on ajax request

Question

I'm trying to create a record from a form. I've used railscast 136 as ground work. When I trying to submit I get a 500 error for missing partial. I've created the controller correlated javascript view but it is requesting a view with the same name as the model.

error message

Rendered appointments/create.js.erb (3.8ms) Completed 500 Internal Server Error in 12ms

Answer 1

Your stack trace shows

Missing partial appointments/appointment

So it looks like rails is trying to render a partial called appointments/appointments.html or appointments/appointments.js

Does a file called appointments.js.erb or appointments.html.erb exist?

If not then create it.

I however suspect that what you are trying to do is show your appointment as I think you want the code below to update the html of some element on your page

$('#appointments').append('<%= j render(@appointment) %>');

I think you need this line to red

$('#appointments').append('<%= j render :partial => 'appointments/appointment', :formats => :html %>');

Your html view partial should be appointments/_appointment.html.erb
