Routes-problem, probably

Hi there,

I''m still not very good (although I''m getting better) at RoR.
I''m trying
to create a friendship between a user and another user. After using the
"friendships/new.rhtml", fill in the user''s name and hit the
create-button. Now it is suppose to move on to the method "create" but
it can''t find the method "create" in the friendships
controller.

The fault lies either in the "form" of my "new.rhtml" or in
my
routes-file, I''m guessing (since it can''t find a method which
exists)...
But I can''t understand WHY.

It''s probably easy for you to see directly.

Re: Routes-problem, probably

First, you may be having some issues because you''ve got friendships
defined twice in your routes (one ''top-level'' and the other
nested
under users).  Just a guess, but url_for might be getting confused.
Better to used the named route to eliminate confusion.

<% form_for(:friendship, :url =>user_friendships_path(@current_user) )
do |f| %>
 ...
<% end %>

Re: Routes-problem, probably

I don''t think it will get confused. But run ''rake
routes'' to see what
kind of url helpers you can use. It is probably something like AndyV
mentions.

Re: Routes-problem, probably

Okay, thanks for the input and suggestion both of you. I tried using the 
snippet below, but I still recieve the same error "Unknown action, No 
action responded to create"

<% form_for(:friendship, :url =>user_friendships_path(@current_user) )
do |f| %>

The first "map.resources :friendships" dosen''t seem to
confuse Create
part of the routes (i recieve the same result with or without), it only 
gives me more possible routes for other stuff related to friendships.

I have a hard time understanding routes, so bare with me. What I could 
understand (and which may be wrong) of the information recieved from the 
"raked routes" is: that the route is incomplete (maybe?)

With my New method which is displayed with the New view (and I believe 
to understand this)
##########################################################
new_user_friendship GET    /users/:user_id/friendships/new 
{:action=>"new", :controller=>"friendships"}
##########################################################
Submitting the form from New it should pass it on to the Create method 
so it will get POSTed. But here is where I get confused. When I raked 
the routes the two Creates can be found without any "home" (like the
one
above). I figure this is what is wrong.
################################################
POST   /users/:user_id/friendships
{:action=>"create", :controller=>"friendships"}
POST   /users/:user_id/friendships.:format
{:action=>"create", :controller=>"friendships"}
################################################

Any suggestions of how to solve it? Am I right about this beeing the 
this which is wrong? Maybe there is more to this which is screwing it 
up?

Re: Routes-problem, probably

a quick update...I tried to create a "home" for the Create in the
routes
in the
"user.resources :friendships, :member => { :accept => :get}"
by adding the ", :create => :post" to the above. But no further 
success...don''t even know if this was right to do.
