cubicweb.appobject

The AppObject class

The AppObject class is the base class for all dynamically loaded objects (application objects) accessible through the vregistry.

We can find a certain number of attributes and methods defined in this class and common to all the application objects.

class cubicweb.appobject.AppObject(req, **extra)[source]

Bases: logilab.common.registry.RegistrableObject

This is the base class for CubicWeb application objects which are selected in a request context.

The following attributes should be set on concrete appobject classes:

At selection time, the following attributes are set on the instance:

_cw
current request
cw_extra_kwargs
other received arguments

And also the following, only if rset is found in arguments (in which case rset/row/col will be removed from cwextra_kwargs):

cw_rset
context result set or None
cw_row
if a result set is set and the context is about a particular cell in the result set, and not the result set as a whole, specify the row number we are interested in, else None
cw_col
if a result set is set and the context is about a particular cell in the result set, and not the result set as a whole, specify the col number we are interested in, else None
