# Rails 7.1 allows infinite ranges for LengthValidators and Clusivity validators

Rails 7.1 allows infinite ranges for LengthValidators and Clusivity validators

Rails 7.1 adds support for infinite ranges for Active Model validations, which
use the `:in`, and `:within` options. It was already possible to query using
infinite ranges in Active Record like so:

```ruby
Book.where(purchases: 20..)
# Returns a collection of records with purchases from 20 and upwards.
Book.where(purchases: ..20)
# Returns a collection of records with purchases from 20 and below.
```

But the same idea of using infinite ranges in Active Model validations was
limited in scope. Rails 7.1 extends this scope of usage by adding support for
infinite ranges in Active Model validations. For example, validating the length
of `first_name` without an upper bound for a `User` will be as simple as
writing:

```ruby
class User
    # ...
    validates_length_of :first_name, in: 20..
end
```

The length of the `:first_name` does not have an upper bound. As long as the
length is greater than or equal to 20, it will remain valid.

The above example also holds true when using the `:within` option as well:

```ruby
class User
    # ...
    validates_length_of :first_name, within: 20..
end
```

In a similar example, let's look at how we would use Active Model validations
along with the `:inclusion` option:

```ruby
class User
    # ...
    validates :age, inclusion: { in: proc { (25..) } }
end
```

The above example would validate the `:age` field such that, it's value needs to
be 25 or above for the record to be valid.
