REST hidden_field verb hack and observe_form conflict?

Listers,

I have in routes.rb...

  map.resources :posts, :member => { :preview => :post }

...in posts/_edit.rhtml...

  <% remote_form_for :post, :url => task_path(@post), :id =>  
''edit_form'' ) do |f| %>
     # rest of the form goes here
  <% end %>
  <%= observe_form "edit_form", :url => preview_post_path(@post)
%>

What happens is that the routing code receives the hidden  
"_method=put" field from the serialised form and thinks I am doing a  
PUT when I am actually trying to do a POST. Needless to say a route  
to my preview function can''t be found and the app barfs out a routing  
error.

Would you say this a bug in the routing code, the observe_form code  
or just a nasty usage of the form helper on my part?

Re: REST hidden_field verb hack and observe_form conflict?

Christos,

Just thinking from a RESTful perspective; Your route is using :member
=> { :preview => :post }.  Given that POST should be mapped to an SQL
INSERT shouldn''t you rather be using :new => { :preview => :post
}
instead if your intention is to POST a new instance of your resource?
Otherwise it would make more sense to use :member => { :preview
=> :put } in case you are want to UPDATE an existing resource object.

Re: REST hidden_field verb hack and observe_form conflict?

Robert,

I have both a :new => { :preview => :post } for new Post previews and  
a :member => { :preview => :post } for previewing of existing Posts,  
when they are edited.

But I think you are right, it should be :member => { :preview  
=> :put } for my edit previews. That should solve my conflict,  
although I am still uncertain if the routing behaviour is right when  
it receives conflicting commands (a POST with a hidden _put).

Cheers!
