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 ...
If I open a shell on an instance of cw 3.24 something seems off
>>> list(schema['CWUniqueTogetherConstraint'].relation_definitions())[0][0].cardinality
# <bound method CubicWebRelationSchema.wrapped of <constraint_of [CWUniqueTogetherConstraint,CWEType]>>
We have been sorting on a method the whole time ? Is it possible what
were the effects ?
1) We cannot sort function can't we ?
>>> def adder(i): return lambda x: x+i
>>> sorted(map(adder,range(10)))
[<function __main__.<lambda>>,
<function __main__.<lambda>>,
...
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.
=====================================================
|cubicweb| - The Semantic Web is a construction game!
=====================================================
|cubicweb| is a semantic web application framework, licensed under the LGPL,
that empowers developers to efficiently build web applications by reusing
components (called `cubes`) and following the well known object-oriented design
principles.
Main Features
~~~~~~~~~~~~~
* an engine driven by the explicit :ref:`data model
<TutosBaseCustomizingTheApplicationDataModel>` of the application,
* a query language named :ref:`RQL <RQL>` similar to W3C's SPARQL,
* a :ref:`selection+view <TutosBaseCustomizingTheApplicationCustomViews>`
mechanism for semi-automatic XHTML/XML/JSON/text generation,
* a library of reusable :ref:`components <Cube>` (data model and views) that
fulfill common needs,
* the power and flexibility of the Python_ programming language,
* the reliability of SQL databases, LDAP directories, Subversion and Mercurial
for storage backends.
Built since 2000 from an R&D effort still continued, supporting 100,000s of
daily visits at some production sites, |cubicweb| is a proven end to end solution
for semantic web application development that promotes quality, reusability and
efficiency.
