Map.namespace, rake routes yields no POST URLs

Rails
1

routes.rb

map.namespace :admin do |admin|
admin.resources :cupcakes
end

rake routes

cupcakes GET /cupcakes
formatted_cupcakes GET /cupcakes.:format
POST /cupcakes
POST /cupcakes.:format

That said, what the heck goes here:

form_for(:cupcake, @cupcake, xxx_url) # ???

Calling create_admin_cupcake_url yields…

undefined local variable or method ‘create_admin_cupcake_url’

Additionally, calling form_for(@cupcake) yields…

undefined method ‘cupcake_path’

Finally, I’ve also tried…

form_for(:cupcake, @cupcake, admin_cupcake_url, :method => :put)

Which points to this URL:
/admin/cupcakes/1/edit

And gives me this view:

Unknown action
No action responded to 1

Routing and URL helpers (what do I use when?) have been the biggest
barrier to creating a RESTful app.

I’ve watched the Railscasts video and read the 2.0 release notes, and
yes, the new stuff sure looks tasty, but it’s useless if I can’t get it
to work.

Try:

form_for([:admin, @cupcake])

Wow. It worked. Where’s the documentation for that?

Thank you so much, Gerjan. You’re a life-saver.

form_for(:cupcake, @cupcake, admin_cupcake_url, :method => :put)

By the way, that didn’t work because you forgot to supply the cupcake id
to the admin_cupcake_url helper. It should’ve been:

form_for(:cupcake, @cupcake, admin_cupcake_url(@cupcake), :method =>
:put)

Hmm, the only hint I see there is the parameter name,
record_or_name_or_array, so I’m not sure how you deduced the solution,
but whatever works. :slight_smile:

Straight from the docs (last entry under “Relying on record
identification”):

Nay. Although, true, in my example I didn’t pass @cupcake to the _url
method, I have indeed tried it, and the result is the same as if I did
not pass it.

form_for(:cupcake, @cupcake, admin_cupcake_url(@cupcake), :method =>
:put)

Yields this URL for form:action…

/admin/cupcakes/1/edit

With no additional field for the HTTP method.

Again the view is the weird:

Unknown action
No action responded to 1

Sure enough. That’s what I get for scanning through the documentation.
Good to know it’s there… :slight_smile:

Hmm, try this:

form_for(:cupcake, @cupcake, :url => admin_cupcake_url(@cupcake),
:method => :put)

Wow, I want to stab myself. Simple, simple mistakes:

form_for(:cupcake, @cupcake, :url => admin_cupcake_path(@cupcake), :html
=> { :method => :put })

I swear I’m not new to this – I just get excited and rush through
things.

LOL. I was moments too late. Thanks again Gerjan! You rock. :slight_smile:

This is actually the correct form:

form_for(:cupcake, @cupcake, admin_cupcake_url(@cupcake), :html => {
:method => :put })

Even so, I still get the same form:action URL (edit instead of update)
and the rendered view complains of an unknown action ‘1’.
