Hi!
Sorry for the newbie question...

I'm following the depot example in AgileWebDevelopmentWithRails.
Stangelly, generating scaffolding using the command (page 53):


	./script/generate scaffold Product Admin

does not generate any .rhtml file, but just:

       exists  app/controllers/
       exists  app/helpers/
       exists  app/views/admin
       exists  test/functional/
   dependency  model
       exists    app/models/
       exists    test/unit/
       exists    test/fixtures/
    identical    app/models/product.rb
    identical    test/unit/product_test.rb
    identical    test/fixtures/products.yml

Any suggestions?

Thanks,
jb

Hi Jose,

>From the listing you included below, I'd say Rails is telling you that views for the 
Admin controller already exist (i.e., line 3 shows 'exists  app/views/admin").  I thought 
the scaffold command would just overwrite anything that was already there, but maybe 
that's been changed.

hth,
Bill

José,

Are you sure that's all the output when you try to generate the
scaffold? It
should also try to generate controllers, etc.

You might check to see that you have the products table created in the
database, because the generator will abort while still incomplete if you
don't have the table.

Hi, Jeff!
Yes, I've got the table:
sqlite> .tables
products
sqlite> .schema
CREATE TABLE products (id integer primary key, title text,
description text, image_url text, price numerical);

Yes, I've generated the model (product) and the controller (admin).
jbonnet$ ls -lisap app/controllers/ app/models/
app/controllers/:
total 24
2721789 0 drwxr-xr-x   5 jbonnet  jbonnet  170 Apr 20 17:51 ./

2724171 8 -rw-r--r--   1 jbonnet  jbonnet  455 Apr 20 16:22 product.rb

Neverthless:
jbonnet$ ./script/generate scaffold product admin
       exists  app/controllers/
       exists  app/helpers/
       exists  app/views/admin
       exists  test/functional/
   dependency  model
       exists    app/models/
       exists    test/unit/

         skip    app/models/product.rb
    identical    test/unit/product_test.rb
    identical    test/fixtures/products.yml

So, no views:-(

Just in case: try deleting the /admin folder.

I'm not sure what you mean by this, but if you mean that you've done:

./script/generate controller Admin

When you generate a controller it creates an empty /view/<controller
name> folder that won't be overwritten by future generates. Whereas if
you do:

./script/generate scaffold Product Admin

It creates a controller, a model, and the /view/admin files.

Hi, Adam!
Just did it:
1. removed .../views/admin
2. jbonnet$ ./script/generate scaffold Product Admin
       exists  app/controllers/
       exists  app/helpers/
       create  app/views/admin
       exists  test/functional/
   dependency  model
       exists    app/models/
       exists    test/unit/
       exists    test/fixtures/
       create    app/models/product.rb
    identical    test/unit/product_test.rb
    identical    test/fixtures/products.yml

That is, files in ../views/admin don't get generated.
I'm using the following versions:
jbonnet$ rails -v
Rails 1.1.2
jbonnet$ ruby -v
ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]

thanks,
jb

Ok, I've found it!
I've upgraded to ruby 1.8.4, deleted .../app/views, and rerun

	./script/generate scaffold Product Admin

Now I have all the files I need:
jbonnet$ ./script/generate scaffold Product Admin
       exists  app/controllers/
       exists  app/helpers/
       create  app/views/admin
       exists  test/functional/
   dependency  model
       exists    app/models/
       exists    test/unit/
       exists    test/fixtures/
         skip    app/models/product.rb
    identical    test/unit/product_test.rb
    identical    test/fixtures/products.yml
       create  app/views/admin/_form.rhtml
       create  app/views/admin/list.rhtml
       create  app/views/admin/show.rhtml
       create  app/views/admin/new.rhtml
       create  app/views/admin/edit.rhtml
       create  app/controllers/admin_controller.rb
       create  app/helpers/admin_helper.rb
       create  app/views/layouts/admin.rhtml

Thanks a lot!
