title: Customizing controller actions
---

When you install Administrate into your app,
we generate empty controllers for each of your resources.
If you want to create more complex application behavior for a dashboard,
you can overwrite controller actions.

The generated controller will look something like:

```ruby
# app/controllers/admin/foos_controller.rb

class Admin::FoosController < Admin::ApplicationController

  # Overwrite any of the RESTful controller actions to implement custom behavior
  # For example, you may want to send an email after a foo is updated.
  #
  # def update
  #   foo = Foo.find(params[:id])
  #   foo.update(params[:foo])
  #   send_foo_updated_email
  # end

  # Override this method to specify custom lookup behavior.
  # This will be used to set the resource for the `show`, `edit`, and `update`
  # actions.
  #
  # def find_resource(param)
  #   Foo.find_by!(slug: param)
  # end

  # Override this if you have certain roles that require a subset
  # this will be used to set the records shown on the `index` action.
  #
  # def scoped_resource
  #  if current_user.super_admin?
  #    resource_class
  #  else
  #    resource_class.with_less_stuff
  #  end
  # end
end
```

## Customizing Actions

To enable or disable certain actions you could override `valid_action?` method in your dashboard controller like this:

```ruby
# disable 'edit' and 'destroy' links
def valid_action?(name, resource = resource_class)
  %w[edit destroy].exclude?(name.to_s) && super
end
```

Action is one of `new`, `edit`, `show`, `destroy`.
