Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v2.3.8) is shown here.

These similar methods exist in v4.0.2:

validates_acceptance_of(*attr_names) public

Encapsulates the pattern of wanting to validate the acceptance of a terms of service check box (or similar agreement). Example:

  class Person < ActiveRecord::Base
    validates_acceptance_of :terms_of_service
    validates_acceptance_of :eula, :message => "must be abided"
  end

If the database column does not exist, the :terms_of_service attribute is entirely virtual. This check is performed only if :terms_of_service is not nil and by default on save.

Configuration options:

  • :message - A custom error message (default is: "must be accepted")
  • :on - Specifies when this validation is active (default is :save, other options :create, :update)
  • :allow_nil - Skip validation if attribute is nil. (default is true)
  • :accept - Specifies value that is considered accepted. The default value is a string "1", which makes it easy to relate to an HTML checkbox. This should be set to true if you are validating a database column, since the attribute is typecasted from "1" to true before validation.
  • :if - Specifies a method, proc or string to call to determine if the validation should occur (e.g. :if =&gt; :allow_validation, or :if =&gt; Proc.new { |user| user.signup_step &gt; 2 }). The method, proc or string should return or evaluate to a true or false value.
  • :unless - Specifies a method, proc or string to call to determine if the validation should not occur (e.g. :unless =&gt; :skip_validation, or :unless =&gt; Proc.new { |user| user.signup_step &lt;= 2 }). The method, proc or string should return or evaluate to a true or false value.
