ActiveRecord::StrictValidations

ActiveRecord::StrictValidations adds validations to ActiveRecord models to make sure they do not trigger database errors.

Installation

Add this line to your application's Gemfile:

gem 'activerecord_strict_validations'

Usage

create_table "events" do |t|
  t.string   "name"
  t.string   "email", limit: 128
  t.text     "description"
  t.integer  "people_count"
end

class Event < ActiveRecord::Base
  validates_strict_columns
end

# String columns

event = Event.new(name: '.' * 400)
event.valid? # => false

event = Event.new(name: '.' * 255)
event.valid? # => true

event = Event.new(email: '.' * 200)
event.valid? # => false

event = Event.new(email: '.' * 100)
event.valid? # => true

# Text columns

event = Event.new(description: '.' * 70000)
event.valid? # => false

event = Event.new(description: '.' * 65535)
event.valid? # => true

# Integer columns

event = Event.new(people_count: 9999999999)
event.valid? # => false

event = Event.new(people_count: 2147483647)
event.valid? # => true

Options

You can use a few options when calling validates_strict_columns:

class Event < ActiveRecord::Base
  validates_strict_columns, only: [:name]
end

class Event < ActiveRecord::Base
  validates_strict_columns, except: [:people_count]
end

Todo

• Support other database column types that raise an exception when given a wrong value.
