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(0);', :class => 'alert tiny button', :data => {'reveal-id' => :RevealDelete}
= render 'layouts/reveal_delete', :item => event_display(@event.event), :resource => @event

Then in my partial,

#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

How can I have this has as something like:

link_to 'Delete', '#', :partial => 'layouts/delete', :remote => :true? 

so that I only render that partial when clicked and not when the page loads?

Answer 1

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.

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

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.
