Fix sorting key for rdefs in schema viewer With changeset 234ca3cbbb46, clicking in the schema of an entity with cubicweb in py3 on "vue en boite" will probably result in an infinite spinner (which implies cw > 3.26) What happened ? This "vue en boite" used to work at least until... hg diff -c a8c1ea390400 cubicweb/schema.py @@ -993,10 +992,6 @@ class CubicWebRelationSchema(PermissionM return False return True - @deprecated('use .rdef(subjtype, objtype).role_cardinality(role)') - def cardinality(self, subjtype, objtype, target): - return self.rdef(subjtype, objtype).role_cardinality(target) - class CubicWebSchema(Schema): """set of entities and relations schema defining the possible data sets But, wait ...

Yes we can. 2) what does it means. >>> { adder(1) : 1 } Out[19]: {<function __main__.<lambda>>: 1} In fact the function object as a __hash__ method (which is practical for making memoizers (cache)), and return truly random results (pseudo random). My take on this patch is relations have NEVER been sorted by cardinality. No one never ever noticed. Hence, I propose to not fix a bug that never was reported.

:ref:`identifier` ou :ref:`label <identifier>`

Label required of referencing node which as no title, else the node's title will be used.


To API objects
--------------
See the autodoc sphinx extension documentation. Quick overview:

* ref to a class: :class:`cubicweb.devtools.testlib.AutomaticWebTest`

* if you can to see only the class name in the generated documentation, add a ~:
  :class:`~cubicweb.devtools.testlib.AutomaticWebTest`

* you can also use :mod: (module), :exc: (exception), :func: (function), :meth: (method)...

* syntax explained above to specify label explicitly may also be used
