"rails server" say "default_controller_and_action" : missing ...

Reported by Marcel Fallier | October 1st, 2010 @ 02:43 PM

Hi gang,

--- my conf ----- Rails 3.0.

Windows 7.

--- description ---- I just create a new app, generating models, creating a standalone database migration to add data (encoded in utf-8), running it no problems.
Then, I've generate a controller :

rails generate controller home index creer .... all good.

I've updated routes.rb to have the root pointing to home#index AND deleted public/index.html.

So I want to check it :

rails server

I've uploaded the entire application for you guys to check it out. I'm new to rails 3.0, so I may be missing something.... though I don't know what.

--- error & stacktrace---- Command :

rails server succeed but fails after ~3 seconds, saying :

Hi again,

is it because a controller cannot have an action with a dash, like :

generate controller home index recup-password

?

Sorry?

I am having the same problem and I am using no dashes. I get the following error both from "rails server" and from "rails generate controller...":

/Library/Ruby/Gems/1.8/gems/actionpack-3.0.0/lib/action_dispatch/routing/mapper.rb:147:in default_controller_and_action': missing :controller (ArgumentError)

- Importance changed from “” to “Low”
Ken, please post your routes.rb. This error most likely has to do with misuse of the new routing DSL - I've had the error myself a couple of times.

After further investigation, this is just a symptom of a bigger issue. I am going to open a separate ticket so the subject line will be searchable by others.
Ryan Bigg October 11th, 2010 @ 10:26 PM
- State changed from “new” to “invalid”
Ken Vogt, you never opened the other ticket.

To my knowledge, this issue would occur with an invalid routes.rb file. Closing it because it seems to be User Error.
