pyramid.registry

class Registry(name='', bases=())[source]

A registry object is an application registry. It is used by the framework itself to perform mappings of URLs to view callables, as well as servicing other various framework duties. A registry has its own internal API, but this API is rarely used by Pyramid application developers (it's usually only used by developers of the Pyramid framework). But it has a number of attributes that may be useful to application developers within application code, such as settings, which is a dictionary containing application deployment settings.

For information about the purpose and usage of the application registry, see Using the Zope Component Architecture in Pyramid.

The application registry is usually accessed as request.registry in application code.

settings

The dictionary-like deployment settings object. See Deployment Settings for information. This object is often accessed as request.registry.settings or config.registry.settings in a typical Pyramid application.

introspector

New in version 1.3.

When a registry is set up (or created) by a Configurator, the registry will be decorated with an instance named introspector implementing the pyramid.interfaces.IIntrospector interface.

When a registry is created "by hand", however, this attribute will not exist until set up by a configurator.

This attribute is often accessed as request.registry.introspector in a typical Pyramid application.

notify(*events)[source]

Fire one or more events. All event subscribers to the event(s) will be notified. The subscribers will be called synchronously. This method is often accessed as request.registry.notify in Pyramid applications to fire custom events. See Creating Your Own Events for more information.

class Introspectable[source]

New in version 1.3.

The default implementation of the interface pyramid.interfaces.IIntrospectable used by framework exenders. An instance of this class is created when pyramid.config.Configurator.introspectable is called.

class Deferred(func)[source]

Can be used by a third-party configuration extender to wrap a discriminator during configuration if an immediately hashable discriminator cannot be computed because it relies on unresolved values. The function should accept no arguments and should return a hashable discriminator.

New in version 1.4.

undefer(v)[source]

Function which accepts an object and returns it unless it is a pyramid.registry.Deferred instance. If it is an instance of that class, its resolve method is called, and the result of the method is returned.

New in version 1.4.

class predvalseq[source]

A subtype of tuple used to represent a sequence of predicate values

New in version 1.4.
