render partial on click

Question

I would like to call partials on some standard operations. I am using this method for calling the partial:

 %li= link_to \'Delete Event\', \'javascript:void(         


        

Answer 1

on the view do this:

link_to "Delete #{item}", '/model/confirm_deletion', :method => :delete, :remote => true #add the class and extra attributes if neeeded

on your controller

def confirm_deletion
end

and add a view to the confirm_deletion action in js

#RevealDelete.reveal-modal
  %a.close-reveal-modal ×
  %h3= "Delete #{item}"
  %p Are you sure you want to delete this?
  =link_to "Delete #{item}", resource, :method => :delete, :remote => :true, :confirm => resource, :class => 'button close-reveal-modal'
  %a.button.alert.close-reveal-modal Cancel

:javascript
  $(body).append($('#RevealDelete'));

that would make an ajax request to load that custom confirmation dialog, maybe you want to add some wrapper to insert the dialog instead of using body.append

Answer 2

To add to the accepted answer, I only got it to work after changing the js portion to the following:

$('#div_id').html("<%= escape_javascript(render :partial => 'my_partial') %>");

Without the escape_javascript it was just rendering the partial in the background and not updating the view.

Answer 3

You can do that with javascript like:

<%= link_to "Delete", delete_content_path, :remote => true %>

The action in your corresponding controller then will be this:

My Controller:

def delete_content
  respond_to do |format|               
    format.js
  end        
end 

Then you can create the delete_content.js.erb inside your correct directory of the link and there you put the following code:

delete_content.js.erb

$('#div_id').html("<%= render :partial => 'my_partial' %>");

Then in your view:

delete_content.html.erb

<div id = "div_id">
#this div is html div that will render your partial

</div>

Don't forget to put your partial _my_partial.html.erb in the same folder.
