Just starting with cream
Will Merrell
I am just starting with Cream, but have worked with rails for a couple
of years. I tried to run the instructions in
https://github.com/kristianmandrup/cream-app-active_record, and had
several problems.
One problem is that when I run rails g cream:full_config --orm
active_record --strategy role_string --roles guest user editor admin
it raises an error in the ~/.rvm/gems/ruby-1.9.2-p136/gems/cream-0.8.3/
lib/generators/devise/config/config_generator.rb file. on line 27 it
calls routes_configure! on line 124 and complains that the arguments
don't match. For fun, I added the argument, but then it dies of
something else, and that was deeper than I wanted to take it.
However, it did continue and seemed to do most of what it should have.
But not quite all. During the config run it complained saying
something like:
[WARNING] You provided devise_for :users but there is no model User
defined in your application
It also says this when I try to start the resulting app. This is
curious because there is in fact a user model.
I would like to use Cream, because it directly addresses the structure
I want to use on several upcoming projects. I have used Devise and
Cancan before, so this should be perfect fore what I have in mind. But
I have not yet gotten it going satisfactorily. Any help would be
appreciated.

Thank you so much for your email. I have updated the project a fair bit recently and its been some time since I tested it out creating a project from scratch. I will try that ASAP and release some fixes for any bugs.
Thanks for the clear bug report!
For the devise_for to work with User, the User model must be "decorated" with a devise statement stating which authentication strategies to use as far as I know.
I will try the full config generator tomorrow and make sure it is working.
> rails g cream:full_config --roles guest user editor admin
Active Record and role_string should be the defaults ;)

I just fixed the bugs.
I got the same error running with your sample arguments and now after the fix it runs without problems.
The devise:configure generator was missing an orm argument in the #routes_configure! method like you said and there was also a minor error in one of the gems which cream depend on.
Please let me know if it works for you now :)
Cheers!

Well, not quite.
There still seems to be two problems.
First, the devise integration still raises an error, after which
everything is suspect. See the listing below to see what happened there.
Second, as an experiment I did the devise install and user setup
manually and included a scaffold table so the app would have something
to do. Once I had this working and tested, then I did the
cream:full_config. It breezed though the devise and cancan stuff, and
then started showing problems in the rolls part. It seems it went to
modify the user model and did odd things to it that broke it. The error
message below
[WARNING] You provided devise_for :users but there is no model User
defined in your application
first appears part way though this run as you can see below.
I think that the code that inserts the roles stuff is doing it wrong and
it may be messing up something else. I tryed a little editing of the
user file after the run, but could not find a way that worked.
Please take a look and give me some guidance.

Here is the resulting user.rb file:
================= user.rb ================
use_roles_strategy :role_string
class User
valid_roles_are Cream::Role.available < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable, :lockable and :timeoutable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me
end
================ end user.rb ================
Below is the output from running this:

===============================================================================
Some setup you must do manually if you haven't yet:
1. Setup default url options for your specific environment. Here is an
example of development environment:
config.action_mailer.default_url_options = { :host =>
'localhost:3000' }
This is a required Rails configuration. In production it must be the
actual host of your application
2. Ensure you have defined root_url to *something* in your
config/routes.rb.
For example:
root :to => "home#index"
3. Ensure you have flash messages in
app/views/layouts/application.html.erb.
For example:
<p class="notice"><%= notice %></p>
<p class="alert"><%= alert %></p>

================== End of output for devise failure: ===================
Kristian Mandrup
Was mssing class macro call
use_orm :active_record
in order to insert code correctly into the User model. Thats why devise complained, coz the code was inserted after User but before < ActiveRecord::Base
Will Merrell
Sorry, something with the devise integration is still not right. Below I
include the output from the run. It failed on the creation of the devise
user file. It did insert the devise_for into the routes file, but it did
not create the migration file and it did not create the model file.
