ErrorsToSentences

This gem allows combining multiple error messages of one attribute into one sentence.

For more, see Usage section

Add this line to your application's Gemfile:

gem 'errors_to_sentences'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install errors_to_sentences

To generate sentence errors just call .to_sentences method on instance errors. For an instance:

Let's say we have a model that looks like:

class Refueling < ApplicationRecord
  belongs_to :user

  with_options numericality: { greater_than: 0 } do
    validates :liters,     presence: true
    validates :kilometers, presence: true
    validates :cost,       allow_nil: true
  end
end

$ refueling = Refueling.new
 => #<Refueling id: nil, user_id: nil, liters: nil, cost: nil, kilometers: nil, avg_fuel_consumption: nil, note: nil, created_at: nil, updated_at: nil>

$ refueling.validate!
 ActiveRecord::RecordInvalid (Validation failed: User must exist, Liters is not a number, Liters can't be blank, Kilometers is not a number, Kilometers can't be blank)

$ refueling.errors.full_messages
 => ["User must exist", "Liters is not a number", "Liters can't be blank", "Kilometers is not a number", "Kilometers can't be blank"]

and now .to_sentences method

$ refueling.errors.to_sentences
 => ["User must exist", "Liters is not a number and can't be blank", "Kilometers is not a number and can't be blank"]
