Instance Method Details

#default_validation_context ⇒ Symbol

The default validation context for this Resource. This Resource’s default context can be overridden by implementing #default_validation_context

Returns:

  • (Symbol) —

    the current validation context from the context stack (if valid for this model), or :default

end

#errors ⇒ ViolationSet

Returns the collection of current validation errors for this resource.

Returns:

  • (ViolationSet) —

    the collection of current validation errors for this resource

# File 'lib/aequitas.rb', line 45

#valid?(context_name = default_validation_context) ⇒ Boolean

Check if a resource is valid in a given context

Returns:

  • (Boolean)

  validation_violations(context_name).each { |v| errors.add(v) }

  self
end

#validation_attribute_value(attribute_name) ⇒ Object

Retrieve the value of the given property name for the purpose of validation. Default implementation is to send the attribute name arg to the receiver and use the resulting value as the attribute value for validation

Parameters:

  • attribute_name (Symbol) —

    the name of the attribute for which to retrieve the attribute value for validation.
