Railsapp/db/migrate Newbie question

I made a mistake when making my first app. I did not use the:
ruby script/generate model

method for creating my models. I more or less hand crafted each og
them. Is there a way to go back so I get my db migration scripts to
populate?

just run script/generate model . I’m pretty sure the
generator
won’t over-write existing files, so you’ll get test and migration files
generated. Before you do, make a backup/commit your work - just in case
:slight_smile:

if that doesn’t work, I’d just copy your model files outside of the
models
directory, run script/generate model and then copy the model files back

That’s what I was doing, thanks! Just wanted to make sure there wasn’t
a simple® way via rake or something.

You could also leave the models and use ‘script/generate migration’
There doesn’t need to be a one-to-one from model to migration.

thanks!

Here’s a follow-up questionon on models and tables:

Should I keep a one for one correspondence of models to tables? For
example, I have a couple of tables that I chose not to model - should I
set up a very small model for those tables as placeholders?

If you want to access a table through ActiveRecord methods, you need to
have a model. So the answer is almost certainly yes.

Mind you, a model doesn’t have to have anything in it. A “blank” model
like

class Widget < ActiveRecord::Base
end

is sufficient to be able to work with all the fields in your table via
ActiveRecord. It is also necessary.
