# ActiveModel Lint for RSpec

Form objects are a great way to move logic out of your controllers and models while ensuring that classes focus on their core responsibility. When you implement ActiveModel behavior in a class, this gem provides a one-line test to ensure that your class implements required behavior such as the ````#persisted?```` method that is required for your form object to function within a Rails form.

The code here was shamelessly cribbed from an example published by [Mike Gehard](http://github.com/msgehard) at Pivotal Labs. It appears in this [blog post](http://pivotallabs.com/making-sure-you-implement-the-activemodel-interface-fully/). This gem merely puts the shared example into a gem for easy distribution into your project.

## Example

Just one line to attach the shared example to your spec.

```ruby

describe MyFormObjectClass do

  it_behaves_like 'an ActiveModel'

end

```

Then run your specs:

```

MyFormObjectClass

  behaves like an ActiveModel

    test persisted?

    test to param

    test to partial path

    test to key

    test model naming

    test errors aref

```

## Installation

###Rails and other Bundler projects

Add the gem to your test group.

```ruby

group :test do

  gem "active_model_lint-rspec"

end

```

### Other Ruby projects

Require the gem after RSpec has been required.

```ruby

require 'rspec'

require 'active_model_lint-rspec'

```
