Hi team, I’m a very newbie RoR user from Spain and I’m developing a
blog’s CMS. Why RoR?, coz I think it’s an amazing framework with many
posibilities, portable and really powerful, with a young and optimist
community, and taking my project I’ve prefered his structure in front of
LAMP. Another thing is that I’ve liked to surprise my masters with this
novel framework. I wish come here to contribute when my application is
finished and when my knowledge in RoR grows.
By now I need some basic help (some directives) about blog creation.
I’ve developed account administration with auth_generator plugin and
touching some code, but I don’t know how can I make every user will
create and configure only one blog at a time (it’s 1 user = 1 blog, 1:1
relation).
CONSIDERATIONS:
1 user has 1 blog
1 blog has 1 style and belongs to 1 category
1 blog has many articles
1 blog has many links
1 article has many comments

After creating scaffold with script generator I’ve touched models like
this:
/app/models/blog.rb
class Blog < ActiveRecord::Base
belongs_to :category
belongs_to :user
…
end
/app/models/user.rb
class User < ActiveRecord::Base
has_one :blog
…
end
And at the end I’ve touched auth_generator account menu (from layout)
adding a link to new blog:
But any user can create infinite blogs from his link on menu and can
list and edit other user’s blogs using navigator’s bar. List option
problem is easy to resolve by erasing this action on blog’ controller,
but not so about edit and create options.
Thanks to all, and I wish my newbie problems and my english won’t
suppose an annoyance to you
