Scaffolding w/ Rails 2.0 - Is there a way to do the models first?
I was playing around with the new scaffold generator and I noticed that if I generated a model first (which creates a migration) and updated the migration for the model... and then tried to do a scaffold of the model, the generator won''t create any usable views or controller. Essentially, it''s not reading the model or database when creating the scaffold. But if delete the model and the migration... and run the scaffold again w/ the data structure of the model specified, it will create a usable controller and views. <b>My questions is:</b> Is there a way to create the models first and then create the scaffolds... now that the old scaffold generator has been removed? ~ mel --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: Scaffolding w/ Rails 2.0 - Is there a way to do the models first?
Hi Mel,
I''m not really a rails pro, but from my understanding, if you create a
new scaffold, the rails generators will automatically create a
controller, model and scaffold/view.
Fairly good in my view, but it does take some getting used to.
For Example....
<code>
rails testing
cd testing
ruby script/generate scaffold MODELNAME
</code>
(Of course replacing MODELNAME with a new model name (that hasn''t yet
been created) like Products)
This will create these files:
exists app/models/
exists app/controllers/
exists app/helpers/
create app/views/products
exists app/views/layouts/
exists test/functional/
exists test/unit/
create app/views/products/index.html.erb
create app/views/products/show.html.erb
create app/views/products/new.html.erb
create app/views/products/edit.html.erb
create app/views/layouts/products.html.erb
create public/stylesheets/scaffold.css
dependency model
exists app/models/
exists test/unit/
exists test/fixtures/
create app/models/product.rb
create test/unit/product_test.rb
create test/fixtures/products.yml
create db/migrate
create db/migrate/001_create_products.rb
create app/controllers/products_controller.rb
create test/functional/products_controller_test.rb
create app/helpers/products_helper.rb
route map.resources :products
Hope this answers your question...

Re: Scaffolding w/ Rails 2.0 - Is there a way to do the models first?
AFAIK, the scaffold generator will only generate the views based on what you provide it at the command line, If you''ve already created your model, don''t sweat! just add the field names and types when you generate the scaffold, choose No when it asks to overwrite your model migration and fixtures. It will generate the views based on what you provided it. e.g ruby script/generate scaffold name:string description:text category_id:integer would create the views with f.text_field(:name), f.text_area(:description) and (i wish) f.collection_select(:category_id, @categories, :id, :name) not that DRY a solution, but better than writing them yourself. Look into make_resourceful by hampton caitlin, which rocks as a replacement RESTful scaffold generator.

Re: Scaffolding w/ Rails 2.0 - Is there a way to do the models first?
Thanks Joe. Good suggestion on just specifying the variables again and it wouldn''t be that big a deal except they are specified differently then in the migration... which means I have to do more than just copy/ pasting. It is better than creating it all by hand but hopeful they address this. I will check out make_resourceful. Hope that will address the issue.
