c5bee480b0 And please note using this flag would incur performance cost. The base model maintains a map of polymorphic keys to subclasses. class cqlengine.models.Model(**values) Creates an instance of the model. If you are not using CsrfViewMiddleware, then you must use csrfprotect on any views that use the csrftoken template tag, as well as those that accept the POST data. if the insertion didnt applied, a LWTException exception would be raised. For instance, suppose you want a table that stores rows of pets owned by an owner: class Pet(Model): tablename = 'pet' ownerid = UUID(primarykey=True) petid = UUID(primarykey=True) pettype = Text(polymorphickey=True) name = Text() def eat(self, food): pass def sleep(self, time): pass class Cat(Pet): polymorphickey = 'cat' cuteness = Float() def tearupcouch(self): pass class Dog(Pet): polymorphickey = 'dog' fierceness = Float() def barkallnight(self): pass After calling synctable on each of these tables, the columns defined in each model will be added to the pet table. For POST forms, you need to ensure:.
As with CQL, the first primary key is the partition key, and all others are clustering keys, unless partition keys are specified manually using partitionkey partitionkey If True, this column is created as partition primary key. There may be many partition keys defined, forming a composite partition key clusteringorder ASC or DESC , determines the clustering order of a clustering key. Primary key fields always require values. If left blank, the table name will be the name of the model, with its module name as its prefix. To setup a polymorphic model structure, follow these steps Create a base model with a column set as the polymorphickey (set polymorphickey=True in the column definition) Create subclass models, and define a unique polymorphickey value on each Run synctable on each of the sub tables About the polymorphic key The polymorphic key is what cqlengine uses under the covers to map logical cql rows to the appropriate model type. Currency:. Compaction Options As of cqlengine 0.7 weve added support for specifying compaction options.
