# Validators
[](https://travis-ci.org/fnando/validators)
[](https://codeclimate.com/github/fnando/validators)
[](https://rubygems.org/gems/validators)
[](https://rubygems.org/gems/validators)
Add some nice ActiveModel/ActiveRecord validators.
## Installation
```
gem install validators
```
Then add it to your Gemfile:
```ruby
gem "validators"
```
## Usage
**Notice**: Some validators will require additional dependencies; whenever you
get a message like
`gem-name is not part of the bundle. Add it to your project's Gemfile.`, all you
have to do is adding that gem to your own project's Gemfile.
### validates_email_format_of
```ruby
class User < ActiveRecord::Base
# old fashion
validates_email_format_of :email
# alternative way
validates :email, email: true
end
```
By default, it rejects disposable e-mails (e.g. mailinator). This loads a lot of
data (~1.7MB), but you can disable this validation by setting
`disposable: true`.
```ruby
class User < ActiveRecord::Base
validates_email_format_of :email, disposable: true
end
```
You can also validate the tld.
```ruby
class User < ActiveRecord::Base
validates_email_format_of :email, tld: true
end
```
### validates_url_format_of
```ruby
class User < ActiveRecord::Base
validates_url_format_of :site
# validates TLD against list of valid TLD.
# Loads ~10KB of text.
validates_url_format_of :site, tld: true
end
```
### validates_ownership_of
```ruby
class Task < ActiveRecord::Base
belongs_to :user
belongs_to :category
validates_ownership_of :category, with: :user
end
user = User.find(1)
another_user = User.find(2)
user_category = user.categories.first
another_user_category = another_user.categories.first
task = user.tasks.create(category: user_category)
task.valid?
#=> true
task = user.tasks.create(category: another_user_category)
task.valid?
#=> false
```
### validates_ip_address
```ruby
class Server < ActiveRecord::Base
validates_ip_address :address
validates_ip_address :address, only: :v4
validates_ip_address :address, only: :v6
end
```
### validates_datetime
```ruby
class Server < ActiveRecord::Base
validates_datetime :starts_at
validates_datetime :ends_at, after: :starts_at, if: :starts_at?
validates_datetime :ends_at, after: :now
validates_datetime :ends_at, before: :today
validates :starts_at, datetime: true
end
```
### validates_cpf_format_of
```ruby
class User < ActiveRecord::Base
validates_cpf_format_of :document
end
```
### validates_cnpj_format_of
```ruby
class User < ActiveRecord::Base
validates_cnpj_format_of :document
end
```
### validates_hostname
Rules:
- maximum length of hostname is 255 characters
- maximum length of each hostname label is 63 characters
- characters allowed in hostname labels are a-z, A-Z, 0-9 and hyphen
- labels do not begin or end with a hyphen
- labels do not consist of numeric values only
- TLD validation (optional)
```ruby
class Server < ActiveRecord::Base
validates_hostname :hostname
validates_hostname :hostname, tld: true
end
```
### validates_username / validates_subdomain
A valid username/subdomain follows the hostname label validation:
- maximum length is 63 characters
- allowed characters are a-z, A-Z, 0-9 and hyphen
- cannot begin or end with a hyphen
- cannot consist of numeric values only
The compiled list will be used for both username and subdomain validations. This
validation loads ~20KB of text.
```ruby
class Server < ActiveRecord::Base
validates_subdomain :subdomain
end
class User < ActiveRecord::Base
validates_username :username
end
```
You can also provide your own list if you want. Any string that starts with `/`
will be parsed with `Regexp.compile`.
```ruby
ReservedUsernames = Validators::ReservedHostnames.parse_list([
"www",
"/www[0-9-]+/"
])
class User < ActiveRecord::Base
validates_username :username, in: ReservedUsernames
end
```
To disable the reserved validation, use `reserved: false`.
```ruby
class User < ActiveRecord::Base
validates_username :username, reserved: false
end
```
