Assocations between models

[mxrgus pxrt]

Post
- id
- title
- text

Comment
- post_id
- id
- text

I have noted belongs_to and has_many relations in ar models.

padrino-gen admin_page post
padrino-gen admin_page comment


If I add in admin new comment, its possible to write ID of post, but
not possible to select it from drop down box - also when opening post
the comments are not shown.

Is or will there be any functionality what automatically generate this
code?

I should modify controllers and views? What is the prefered way to do
this?

Yep, now admin didn't create for you the right "controller" for your
association, this simply because it's very tricky do that for all our
adapters, each adapter have their own relationships.

Btw with ar is super simpler "hack" this in you comment form change
this:

=f.text_field :post_id

in

=f.select :post_id, :collection => Post.all

That's all!

Thank you for your response, but this does not do the trick:

padrino-gen project sample_blog -t shoulda -e haml -c sass -s jquery -
d activerecord -b
cd sample_blog
padrino-gen admin
padrino rake ar:create
padrino rake ar:migrate
padrino rake seed

padrino-gen model post title:string body:text
padrino-gen model comment post_id:integer body:text
padrino rake ar:migrate

padrino-gen admin_page post
padrino-gen admin_page comment

# app/models/comment.rb
class Comment < ActiveRecord::Base
belongs_to :post
end

#app/models/post.rb
class Post < ActiveRecord::Base
has_many :comments
end

-#admin/views/comments/_form.haml
.group
=f.label :post_id
=f.error_message_on :post_id
-# =f.text_field :post_id, :class => :text_field

=f.select :post_id, :collection => Post.all

%span.description Ex: a simple text

.group
=f.label :body
=f.error_message_on :body
=f.text_area :body, :class => :text_area
%span.description Ex: a simple text


.group.navform.wat-cf
=f.submit pat(:save), :class => :button
=f.submit pat(:cancel), :onclick =>
"window.location='#{url(:comments, :index)}';return false", :class
=> :button

=f.select :post_id, :collection => Post.all

Yep sorry I forgot that is necessary fields:

=f.select :post_id, :collection => Post.all, :fields => [:name, :id]

where :name is the db filed that you want show.

Works like a charm, thank you for your response. I'll continue
learning your framework now. :)
