Base Account Class

The Account class, similar to the Application class contains a Meta inner-class with meta information (used to build scheme information provided via the GET / endpoint). Also included in the class are vizydrop.fields objects that correspond to the fields required for an account to operate. Classes extending the Account base class must implement some functions for account validation, generation of a tornado.httpclient.HTTPRequest, and friendly name generation:

  • self.get_request(self, url, method='GET', body=None) - generate a HTTPRequest object with current field values for the url and method provided
  • self.validate(self) - returns a tuple (bool, str) indicating if the account is valid and, if not, a string representation of errors
  • self.get_friendly_name(self) - returns a friendly name (str) for the account; this is the default name of an account object when displayed to the end-user

Here is an example of an Account subclass without these functions (import statements excluded for brevity):

class TrelloTokenAuth(Account):
    class Meta:
        identifier = "token"
        name = "Token Authentication"
        description = "Authentication via a manually-generated and" \
        " supplied authentication token retrieved from Trello"

    token = TextField(name="Authentication Token",
    description="Auth token retrieved from Trello")

    token_link = LinkField(name="Token Page",
        default="https://trello.com/1/authorize?key={}&name=Vizydrop" \
        description="Navigate here to retrieve your access token:")

Subclasses and Helpers

There are a series of Account subclasses that provide helper functionality for HTTP Basic and OAuth-style authentication classes:

  • AppHTTPBasicAuthAccount - automatically includes username and password fields for HTTP-basic style authentication, as well as extends the get_request function to automatically include a standards-compliant Authorization: Basic HTTP header.
  • AppOAuthv1Account - automatically includes standard OAuth-v1 fields, such as access_token and access_secret, as well as extends the get_request function to automatically include standards-compliant OAuth query argument, header, or body elements for authentication.
  • AppOAuthv2Account - similar to the AppOAuthv1Account class, only utilizing OAuth-v2.
