Seed -- a seed data/fuzzing plugin

Seed is a plugin to help with generating and/or inserting seed data
into your database. Seed will
generate data for you or load it from fixtures or arbitrary Yaml, CSV,
or (eventually) XML
files. The basic workflow goes like this:

1. Create seed files. These live in db/seeds/ and are named for the
tables of your models,
like +Person+ (model), +people+ (table) would yield +people_seed.rb+.

2. Create a class named for the file (+people_seed.rb+ would have
+PeopleSeed+) that inherits from

3. Fill in your directives for attributes or file loads, or you can
leave it empty and Seed will
enumerate your columns and generate data for you.

4. Run rake db:seed to seed your database.

You can also generate static versions of the seeds for your current
models using the db:seeds:generate
Rake task.

So, let's say you have a model +User+, with attributes +username+
(string), +password+ (string),
+email_address+ (string), favorite_quote (string), and administrator
(boolean). To get a basic seed
file, you need to execute <tt>rake db:seeds:generate</tt>. This task
will yield a file like this:

    class UsersSeed < Seed::Planter
      attribute :username, :string
      attribute :password, :string
      attribute :email_address, :string
      attribute :favorite_quote, :string
      attribute :adminstrator, :boolean

Now, since we have a few special fields, we can use Seed's special
types for +username+, +password+, and +email_address+.

    class UsersSeed < Seed::Planter
      attribute :username, :username
      attribute :password, :password
      attribute :email_address, :email
      attribute :favorite_quote, :string
      attribute :adminstrator, :boolean

This will generate proper data (for example, "jmcanally" rather than
"Lorem ispum dolormet" for username).

Run rake db:seed and voila! A seeded database!

You can also skip specifying a type and provide the data for the field
in a +Proc+. For example, if you wanted to
have some specialized logic for setting the value of a field:

    class JobsSeed < Seed::Planter
      attribute :description, :string
      attribute :script, Proc { ['upload', 'update',
'find_files'].sort { rand(3) - 1 }[0] }

You can also call methods from the seed class in the +Proc+ if you'd
like (direct support for method class on the
seed class will be added soon).
