This is a pre-production deployment of Warehouse, however changes made here WILL affect the production instance of PyPI.
Project Description
Allows to aggregate key-value data from many sources.

Can be used, for example, as a proxy to settings object in Django framework.

The sources of key-value data are appended to MultiRegistry vi append() method, then looked up via standard Python dotted notation, as explained in more detail below.

Upon access, attributes will be looked up in the parent objects in the order the latter were appended.

For example, if we have two settings like objects: A with attribute a and B with attribute b and a third one, found in module importable from 'some.registry.C', we can construct the registry as:

>>>r = MultiRegistry(A, B, ‘some.registry.C’)

or alternatively:

>>>r = MultiRegistry() >>>r.append(A) >>>r.append(B) >>>r.insert(2, ‘some.registry.C’)

Note

The registries can be provided as python objects or dotted python paths. In the latter case an import error will be raised if module at the path does not exist

then access the registry as:

r.b - attrubute b will be first looked up in the object A, then in the object B, where it will be found.

If there is an attribute present in more than one appended object, the first one will be returned - in the same order the registries are stored internally, which takes into account:

  • order the registries were provided at the object initialization
  • order of append() calls.
  • taking into account indices provided with insert() call

If the attribute is not found, attribute error will be raised.
