does not find rjs file

I am using rails 2.3.8 and I'll load a modal dialog box using a partial called _show_venue.html.erb. Inside this partial I add link_to_remote to edit each venue.

_show_venue.html.erb ::

<table>
<tr>
<th>Country</th>
<th>Place</th>
<th>Color</th>
</tr>

<% @venues.each do |venue| %>
<tr>
<td><%=h venue.country_id %></td>
<td><%=h venue.place %></td>
<td><%=h venue.color %></td>

<td><%= link_to_remote 'Edit', :url => {:controller => 'venues', :action => 'edit', :id=>venue.id } %></td>
</tr>
<% end %>
</table>

And this is my controller code ::

def edit
@venue = Venue.find(params[:id])
end

edit.js.rjs ::

page.replace_html 'edit_venue', :partial => '开发者_运维技巧edit_form'
page<< "$j ('#event_actions').dialog({
    title: 'Edit venue
    modal: true,
    width: 500,
    close: function(event, ui) { $j ('#event_actions').dialog('destroy') }
});"

But when I run this, it could not find edit.js.rjs file. Why did this happen? Anyone can explain it?

You should do the following changes to you controller method:

respond_to do |format|    
      format.js      
end

so that it will find the edit.js.rjs and render it.

Edit: The 404 HTTP status which was the main problem was because of a missing route.

A route to match venues/:id/edit should solve the problem.

Rename your file edit.js.rjs to edit.rjs

Edited

I think you have to do it other way as you want dynamic object @venue, Try following

def edit
  @venue = Venue.find(params[:id])
  render :update do |page|
    page.replace_html 'edit_venue', :partial => 'edit_form', :object => @venue
    page<< "$j ('#event_actions').dialog({
      title: 'Edit venue
      modal: true,
      width: 500,
      close: function(event, ui) { $j ('#event_actions').dialog('destroy') }
    });"
   end
 end

your link should be as follows [you have to write :method ]

<%= link_to_remote 'Edit', :url => {:controller => 'venues', :action => 'edit', :id=>venue.id }, :method=>'put' %> 

you can also try 'post' if above doesn't work

rename edit.js.rjs to edit.js.erb

Add the following to the end of your edit method:

respond_to do |format|
  format.js
  format.html
end

restart your server
