Instance Method Details

#add_attribute(attr_name, entry_id, value) ⇒ String

Appends a specific Kaltura::MediaEntry attribute to the end of the original attribute given a Kaltura entry. This method is called by method_missing, allowing this module add attributes based off of the current API wrapper, rather than having to update along side the API wrapper.

Parameters:

  • attr_name (String) —

    The attribute to set.

  • entry_id (String) —

    The Kaltura entry ID.

  • value (String) —

    The value you wish to append the attribute with.

Returns:

  • (String) —

    Returns the value as stored in the Kaltura database. Tag strings come back slightly funny.

Raises:

  • (Kaltura::APIError) —

    Passes Kaltura API errors directly through.
