Rails: ruby script/generate model, where are the docs?

Question

I am running

ruby script/generate scaffold

or

ruby script/generate model

and I know the basic syntax, like

ruby script/generate scaffold Dude name:string face:boolean

but I do not know things like:

• should names of variables have underscores or be camelCased?
• what kind of variable types are acceptable?

Where can I find such information?

THANKS!

P.S. The answers to my two questions would help for now, too :)

Answer 1

This document on Rails Migration would help.

With respect to the naming convention, I think the general adopted convention for Ruby on Rails is to have underscores.

To know which variable types are acceptable, refer to the section on Database Mapping.

Answer 2

To check Rails naming conventions, topfunky's Pluralizer was useful.

Answer 3

Type the command without arguments and the documentation is revealed:

$ script/generate model

You can use either camelcase or underscores for the model name.

• Model names are singular; controller names are plural.
• Field names use underscores.

I can't remember all the possible field types, I just look them up from the Migration docs, as linked above.

Answer 4

There is a resource on the rails wiki as a List of Available Generators.
