Form not invoking "create" action in production

I've officially lost my mind. I've got a form that looks like this:

<%= error_messages_for :avatar %> <% form_for(:avatar, :url => avatars_path, :html => { :multipart => true }) do |f| %>   <p><%= f.file_field :uploaded_data %></p>   <p><%= submit_tag "Upload" %> <% end %>

It uses attachment_fu to allow users to upload avatars. Everything works fine when I'm in development, but in production the "create" action is not invoked from some reason.

I'm using standard RESTful routes, like this:

map.resources :avatars

And I've got a "create" action in my avatars controller:

def create   @avatar = current_user.avatars.build params[:avatar]   respond_to do |format|     if @avatar.save       flash[:notice] = 'Avatar was successfully created.'       format.html { redirect_to avatars_path }       format.xml { head :created, :location => avatars_path }     else       format.html { render :action => "new" }       format.xml { render :xml => @avatar.errors.to_xml }     end   end end

In development, everything works as expected. My production.log file shows me this following when I try to upload a new avatar:

Processing AvatarsController#new (for 203.98.22.198 at 2007-04-02 21:11:35) [GET]   Parameters: {"action"=>"new", "controller"=>"avatars"} Rendering within layouts/application Rendering avatars/new Completed in 0.15629 (6 reqs/sec) | Rendering: 0.01185 (7%) | DB: 0.14027 (89%) | 200 OK

In development, things looks right, though:

I just don't get why the "create" action isn't being invoked in production with this code. Is there something wrong with my form that I'm missing? I can't seem to figure this one out.

Any help would be greatly appreciated.

I've gotten a response from Media Temple on this, although I'm still not sure how I'll resolve the issue. I'm sure I'm not the first or last person who'll try to do what I'm doing, so I'm hopeful that I'll find a solution. Here's what they said:

If anyone has an idea of how to work around this behavior (changing the Apache config?) please let me know. Otherwise, I'll update this post when I figure out a solution.

Their advice is right on, and makes sense once I read it. I had the same problem, and the only thing I can think of is that Mike Clark wasn't using apache when he wrote that tutorial.

Anyway, to work around this you need to use the :path_prefix option in your has_attachment statement inside your model:

## Begin model ## class Mugshot < ActiveRecord::Base

  has_attachment :content_type => :image,                  :storage => :file_system,                  :max_size => 500.kilobytes,                  :resize_to => '320x200>',                  :thumbnails => { :thumb => '100x100>' },                 :path_prefix => "public/something_besides_avatars"

  validates_as_attachment

end ## end model ##

This will prevent apache from hijacking the request because the directory you created to hold the images won't match the rails action you're trying to invoke. Once I changed that setting things started working for me.

Does that help?

Actually, I've added the following to my .htaccess:

DirectorySlash Off

... which solves the problem. You can read more about that here:

http://httpd.apache.org/docs/2.0/mod/mod_dir.html

I was wondering if there's any reason why this shouldn't be a part of the default Rails .htaccess file...?
