In Ruby on Rails is there a way to view the properties of a model

Question

I am using NetBeans to create my first Ruby on Rails application. Is there a way by which I can view all of the properties of a model? Should I just be looking in the database?

Answer 1

I just use db/schema.rb - seems to work fine for me.

Answer 2

You can use the annotate gem for this - it will add comments to the top of each model indicating its properties.

Answer 3

You could call Model.attributes in Rails' console. This gives a hash with all attributes.

Be careful when using this inside your real code as it always recreates the hash and is therefore pretty expensive.

Answer 4

Just type your model name on the rails console then press Enter.

rails c # start your rails console

User

=> User(id: integer, email: string, password_digest: string...)

Answer 5

In case anyone is viewing this and is using a newer version of Rails, you can just call Model in the console. (I'm on Rails 3.2.1 and Ruby 1.9.2p290.)

In fact, calling Model.attributes in this case does not work.

Answer 6

A nice little tool that I use is from MySQL. It is called MySQL Administrator.

It lets me validate that the db (development/test/production), the tables for the db, and finally the columns(attributes).

Answer 7

Model.attributes #=> {'name' => 'foo', 'desc' => 'bar'}
