Both the `matches?` method and the lambda gets the `request` object as an argument.

#### Constraints in a block form
|
||||
|
||||
You can specify constraints in a block form. This is useful for when you need to apply the same rule to several routes. For example
|
||||
|
||||
```
|
||||
class RestrictedListConstraint
|
||||
# ...Same as the example above
|
||||
end
|
||||
|
||||
Rails.application.routes.draw do
|
||||
constraints(RestrictedListConstraint.new) do
|
||||
get '*path', to: 'restricted_list#index',
|
||||
get '*other-path', to: 'other_restricted_list#index',
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
You also use a `lambda`:
|
||||
|
||||
```
|
||||
Rails.application.routes.draw do
|
||||
constraints(lambda { |request| RestrictedList.retrieve_ips.include?(request.remote_ip) }) do
|
||||
get '*path', to: 'restricted_list#index',
|
||||
get '*other-path', to: 'other_restricted_list#index',
|
||||
end
|
||||
end
|
||||
```

|
||||
Route globbing is a way to specify that a particular parameter should be matched to all the remaining parts of a route. For example:
