Error in the tutorial?

Hello everyone!!!

I’m new to Rails… I’m trying to follow the first tutorial steps, but
I came across this error:

D:\InstantRails\rails_apps\cookbook2>ruby script\generate scaffold
recipe recipe

  exists  app/controllers/
  exists  app/helpers/
  exists  app/views/recipe
  exists  app/views/layouts/
  exists  test/functional/

dependency model
exists app/models/
exists test/unit/
exists test/fixtures/
identical app/models/recipe.rb
identical test/unit/recipe_test.rb
identical test/fixtures/recipes.yml
error Before updating scaffolding from new DB schema, try
creating a tab
le for your model (Recipe)

Any ideas?

Thanks in advance!
Luis

it seems you’d generated model Recipe before you tried to generate a
scaffold.
You can try to destroy the model with: ruby script/destroy model Recipe

Dear Nanyang

Thank you very much for your help :slight_smile:

However, it’s no use: I destroyed both models (category and recipe), and
tried to follow the tutorial, but i get the same error :frowning:

The tutorial I’m following is:

something may have been messed up.
maybe it’s time to start a new project and try this scaffold magic.

Rails is telling you that it can’t find your Recipes table. Make sure
you
do, in fact have one and that it’s named Recipes. It needs to be
plural.
Rails is also telling you that you’ve already got a recipe.rb model.
You
need to delete that file. The only other time I remember a reader
having
this problem, he’d forgotten to save his create.sql script. When he ran
the
script it didn’t complain but, in fact, no table had been created.

hth,
Bill

Oh… Good idea… now… how do I delete cookbook2 project? Just delete
the
directory? Or is there a command line option to delete/destroy it?

Thanks,

You can delete the directory.

And note what Bill said, you may need to check the tutorial again, or
google another scaffolding article, which is easier to follow for you.

Ok. Thanks. I’ll try that…

The tutorial is pretty simple, don’t worry…

Thank you very much for your help.

The recipes and categories tables are created (I know about MySQL
believe
me). And I saved the create.sql script.

I’ll try beginning the tutorial all over again and let you know…
