Included in:
Request
Defined in:

Instance Method Details

#cast_request(data, schema = self.schema) ⇒ Hash

This method casts the data object (of mixed types) into a Hash ready for JSON serialization. The schema will default to the self's schema. You should pass in the schema where possible. This is because objects are serialized differently depending on the context in which they are being written.

Examples:

Recurly::Requests::AccountUpdatable.cast(code: 'benjamin')
#=> {:code=>"benjamin"}
# If you have some mixed data, like passing in an Address, it should cast that
# address into a Hash based on the Schema defined in AccountUpdatable
address = Recurly::Resources::Address.new(city: 'New Orleans')
Recurly::Requests::AccountUpdatable.cast(account_code: 'benjamin', address: address)
#=> {:account_code=>"benjamin", :address=>{:city=>"New Orleans"}}

Parameters:

  • data (Hash, Resource, Request) —

    The data to transform into a JSON Hash.

  • schema (Schema) (defaults to: self.schema) —

    The schema to use to transform the data into a JSON Hash.

Returns:

  • (Hash) —

    The pure Hash ready to be serialized into JSON.
