Class Method Details

.configure {|configuration| ... } ⇒ Object

Configures the WCC::Contentful gem to talk to a Contentful space. This must be called first in your initializer, before #init! or accessing the client. See WCC::Contentful::Configuration for all configuration options.

Yields:

def self.configure
  raise InitializationError, 'Cannot configure after initialization' if @initialized

  @configuration ||= Configuration.new
  yield(configuration)

  configuration.validate!

  configuration
end

.init! ⇒ Object

Initializes the WCC::Contentful model-space and backing store. This populates the WCC::Contentful::Model namespace with Ruby classes that represent content types in the configured Contentful space.

These content types can be queried directly:

WCC::Contentful::Model::Page.find('1xab...')

Or you can inherit from them in your own app:

class Page < WCC::Contentful::Model::Page; end
Page.find_by(slug: 'about-us')

Raises:
