UserAttr.create - Python API

Creates a new user attribute, optionally encrypting it before it is saved in the database. It is also possible to set expiry for an attribute, upon reaching of which the attribute will be no longer available.

An exception is raised if an attribute of a given name already exists - use set if an update should be issued instead of reporting an exception.

Unlike session attributes, user attributes persist across multiple sessions, multiple logins, of the person they belong to.

Attribute names and other metadata may be stored in server logs. Values are never saved to logs.

There are two versions of the call - .create is used with a single attribute and .create_many is used with multiple attributes. Performance-wise, it is more efficient to use .create_many if more than one attribute should be created for a user.

create

user.attr.create(self, name, value, expiration=None, encrypt=False)

  • name: Name of the attribute to create
  • value: An arbitrary value assigned to the name
  • expiration: After how many seconds, from current time, the attribute should expire
  • encrypt: Should the attribute's value be stored encrypted or not
  • Returns: (None)

        # Information about the attribute to be created
        name = 'my-attribute'
        value = 'my-value'

        # Create a new attribute
        user.attr.create(name, value)

create_many

user.attr.create_many(self, data, expiration=None, encrypt=False)

Creates a series of user attributes.

  • data: A list of dictionaries, each describing an attribute to create. If any key is missing, the default value is taken from the method call's parameters.
  • expiration: After how many seconds, from now, the attribute should expire (may be overridden in each dict)
  • encrypt: Should the attribute's value be stored encrypted or not (may be overridden in each dict)
  • Returns: (None)

Dictionaries in the 'data' parameter are in the format below:
