Database Validation

Is a simple way to add Active Record Validations to models and views through the limits established in your database.

Installation

Add this line to your application's Gemfile:

gem 'database-validation'

And then execute:

$ bundle

Or install it yourself as:

$ gem install database-validation

Usage

Models Validation

Add this method to all the models that you want to add validations to all its attributes.

class SomeModel < ActiveRecord::Base
  validate_limits

  # your stuff
end

Or you can pass, as an option, an array with the attributes you want to be skipped for validations OR the few you want to validate.

validate_limits only: [:email]

or

validate_limits except: [:email, :credit_card]

Views Validation

form_for must have an associated object.

<%= form_for @object do |f| %>

form_for automatically adds maxlength option with the value corresponding to the limit of the column in the database to all its text_fields.

However, you can overwrite maxlength option with any value you want or...

Add skip_validations option to your form and set it to true to prevent gem from adding validations.

<%= form_for @object, skip_validations: true do |f| %>
