Given an attribute tuple from a changeset and a resource type, find and append the field from the schema

Parameters

• attr_tuple {attr_name, attr_value} from the changset
• resource_type Module which is responsible for the changset data

Examples

alias Recurly.XML.Field

Recurly.XML.Builder.find_field({:account_code, "xyz"}, Recurly.Account)
#=> {:account_code, "xyz", %Field{name: :account_code, type: :string, opts: []}}

Generates an xml document representing a changeset.

Parameters

• changeset Keyword list changeset
• resource_type Module representing the resource type

Examples

changeset = [account_code: "my_account", first_name: nil]
Recurly.XML.Builder.generate(changeset, Recurly.Account)

# <account>
#   <account_code>my_account</account_code>
#   <first_name nil="nil"></first_name>
# </account>

# if you give it a field that is not in the
# resource's field, it will throw an ArgumentError
# let's assume you misspell account `acount`

changeset = [acount_code: "my_account", first_name: nil]
Recurly.XML.Builder.generate(changeset, Recurly.Account)
#=> raises ArgumentError "Invalid changeset data {:acount, "my_account"} for resource Recurly.Account"

Takes a tuple from changeset data and returns an xml element

Parameters

• changset_tuple - contains the attribute name, the attribute value, and the Recurly.XML.Field.

Examples

alias Recurly.XML.Field

field = %Field{name: :account_code, type: :string, opts: []}

Recurly.XML.Builder.to_element({:account_code, "xyz", field})
#=> {:account_code, nil, "xyz"}

Turns a changeset and associated resource type into a nested tuple which can be turned into xml by XmlBuilder
