Do rails rake tasks provide access to ActiveRecord models?

Question

I am trying to create a custom rake task, but it seems I dont have access to my models. I thought this was something implicitly included with rails task.

I have the following code in lib/tasks/test.rake:

namespace :test do
  task :new_task do
    puts Parent.all.inspect
  end
end

And here is what my parent model looks like:

class Parent < ActiveRecord::Base
  has_many :children
end

It's a pretty simple example, but I get the following error:

/> rake test:new_task
(in /Users/arash/Documents/dev/soft_deletes)
rake aborted!
uninitialized constant Parent

(See full trace by running task with --trace)

Any ideas? Thanks

Answer 1

you might need to require your configuration (which should specify all your required models etc)

eg:

require 'config/environment'

alternatively you can just require each seperately, but you might have environment issues AR not set up etc)

Answer 2

Figured it out, the task should look like:

namespace :test do
  task :new_task => :environment do
    puts Parent.all.inspect
  end
end

Notice the '=> :environment' dependency added to the task
