Build child model after saving parent in jquery rails -

In my train app, I have a nested model and I would like to create a child model after parent's creation and this original Like to do this in the 'edit' view of the model. I am using jquery for parent model.

parent controller

  def can create studio = student.new (student_perm) if the student @dd #### is to make a child model like # here # Student.student_grades.build response_to do | Format | Format.js {render 'edit'} and finally answer. Format.js {Render 'New'} End And End  

Unfortunately the above code is not working. I also have a build line in the edit but it does not help because the rendering goes directly to the scene

Update The problem was not the code above, but the code in the view was the code. Thank you for your help though.

It's possible that just copy it and copy it, but you have a @studate in the second line Used an uppercase 's' on, but using a lowercase on line 3
