class Decidim::TermCustomizer::Import::Parser
This is an abstract class with a very naive default implementation for the importers to use. It can also serve as a superclass of your own implementation.
It is used to be run against each element of an importable collection in order to parse relevant fields. Every import should specify their own parser or this default will be used.

# File lib/decidim/term_customizer/import/parser.rb, line 24 def self.resource_klass raise NotImplementedError, "#{self.class.name} does not define resource class" end
Public Instance Methods
Public: Returns a parsed object with the parsed data.
Returns a target object.
# File lib/decidim/term_customizer/import/parser.rb, line 43 def parse self.class.resource_klass.new(resource_attributes) end
Can be used to convert the data hash to the resource attributes in case the data hash to be imported has different column names than the resource object to be created of it.
By default returns the data hash but can be implemented by each parser implementation.
Returns the resource attributes to be passed for the constructor.
