**"Make validations DRY"**
You need not write validations generated by database schema.
## Features
1. generate validation modules from database schema to `app/validations/` directory
1. automatically includes validation module into corresponding model
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'pretty_validation'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install pretty_validation
## Usage
You can generate validation modules in two ways.
- run the `db:migrate` task, and then automatically generates the modules.
- run the `validation:generate` task
Note: The module is overwritten each time the task.
## Examples
```ruby
# db/migrate/20151105090101_create_users.rb
class CreateUsers < ActiveRecord::Migration
def change
create_table :users do |t|
t.string :name, null: false
t.integer :age, null: false
t.boolean :admin
t.timestamps null: false
end
add_index :users, :name, unique: true
end
end
# app/validations/user_validation.rb
module UserValidation
extend ActiveSupport::Concern
included do
validates :name, presence: true
validates :age, presence: true, numericality: true
validates_uniqueness_of :name
end
end
# app/models/user.rb
class User < ActiveRecord::Base
end
```
And run `rails console`:
```ruby
Loading development environment (Rails 4.2.4)
irb(main):001:0> user = User.new
=> #
irb(main):002:0> user.valid?
User Exists (0.1ms) SELECT 1 AS one FROM "users" WHERE "users"."name" IS NULL LIMIT 1
=> false
irb(main):003:0> p user.errors.full_messages
["Name can't be blank", "Age can't be blank", "Age is not a number"]
=> ["Name can't be blank", "Age can't be blank", "Age is not a number"]
```
