# Destroy Context

Destroy sets up an object using the build functionality, and then attempts to save it to the data source.

Destroy does the following:

- Find a model
- Destroy the model

##### Example

```ruby
class PeopleContext
  include SnFoil::CRUD::DestroyContext

  searcher PeopleSearcher
  policy PersonPolicy
  model Person
end
```

### Required Class Definitions

- Searcher
- Policy
- Model

### Primary Action
Destroys the model.
