Python 2.7 has reached end of support and will be deprecated on January 31, 2026. After deprecation, you won't be able to deploy Python 2.7 applications, even if your organization previously used an organization policy to re-enable deployments of legacy runtimes. Your existing Python 2.7 applications will continue to run and receive traffic after their deprecation date . We recommend that you migrate to the latest supported version of Python .

google.appengine.ext.admin package

Summary

Simple datastore view and interactive console, for use in dev_appserver.

class google.appengine.ext.admin.BackendsPageHandler(*args, **kwargs) source

Bases: google.appengine.ext.admin.BaseRequestHandler

Shows information about an app’s backends.

PATH = '/backends'

get() source: Shows template displaying the app’s backends or a single backend.

get_backend_entry(backend_name) source: Get the BackendEntry for a single backend.

post() source

render_backend_page(backend_name) source: Shows template displaying a single backend.

render_backends_page() source: Shows template displaying all the app’s backends.

class google.appengine.ext.admin.BaseRequestHandler source

Bases: google.appengine.ext.webapp._webapp25.RequestHandler

Supplies a common template generation function.

When you call generate(), we augment the template variables supplied with the current user in the ‘user’ variable and the current webapp request in the ‘request’ variable.

base_path() source

Returns the base path of this admin app, which is chosen by the user.

The user specifies which paths map to this application in their app.cfg. You can get that base path with this method. Combine with the constant paths specified by the classes to construct URLs.

filter_url(args) source

Filters the current URL to only have the given list of arguments.

For example, if your URL is /search?q=foo&num=100&start=10, then

self.filter_url([‘start’, ‘num’]) => /search?num=100&start=10 self.filter_url([‘q’]) => /search?q=10 self.filter_url([‘random’]) => /search?

generate(template_name, template_values={}) source

in_production() source

Detects if app is running in production.

Returns a boolean.

PATH = '/cron'

get(now=None) source: Shows template displaying the configured cron jobs.

class google.appengine.ext.admin.DataType source

Bases: object

A DataType represents a data type in the datastore.

Each DataType subtype defines four methods:

format: returns a formatted string for a datastore value input_field: returns a string HTML <input> element for this DataType name: the friendly string name of this DataType parse: parses the formatted string representation of this DataType python_type: the canonical Python type for this datastore type

We use DataType instances to display formatted values in our result lists, and we uses input_field/format/parse to generate forms and parse the results from those forms to allow editing of entities.

class google.appengine.ext.admin.DatastoreBatchEditHandler source

Bases: google.appengine.ext.admin.DatastoreRequestHandler

Request handler for a batch operation on entities.

Supports deleting multiple entities by key, then redirecting to another url.

PATH = '/datastore/batchedit'

post() source

class google.appengine.ext.admin.DatastoreEditHandler source

Bases: google.appengine.ext.admin.DatastoreRequestHandler

Request handler for the entity create/edit form.

We determine how to generate a form to edit an entity by doing a query on the entity kind and looking at the set of keys and their types in the result set. We use the DataType subclasses for those introspected types to generate the form and parse the form results.

PATH = '/datastore/edit'

get() source

post() source

class google.appengine.ext.admin.DatastoreGetIndexesHandler source

Bases: google.appengine.ext.admin.BaseRequestHandler

PATH = '/datastore_indexes'

get() source

class google.appengine.ext.admin.DatastoreQueryHandler source

Bases: google.appengine.ext.admin.DatastoreRequestHandler

Our main request handler that executes queries and lists entities.

We use execute_query() in our base request handler to parse URL arguments and execute the datastore query.

PATH = '/datastore'

get() source

Formats the results from execute_query() for datastore.html.

The only complex part of that process is calculating the pager variables to generate the Gooooogle pager at the bottom of the page.

get_kinds(namespace) source

Get sorted list of kind names the datastore knows about.

This should only be called in the development environment as metadata queries are expensive and no caching is done.

Parameters

namespace – The namespace to fetch the schema for e.g. ‘google.com’. It is an error to pass in None.

Returns

A sorted list of kinds e.g. [‘Book’, ‘Guest’, Post’] (encoded in utf-8).

class google.appengine.ext.admin.DatastoreRequestHandler source

Bases: google.appengine.ext.admin.BaseRequestHandler

The base request handler for our datastore admin pages.

We provide utility functions for querying the datastore and inferring the types of entity properties.

execute_query(start=0, num=0, no_order=False) source

Parses the URL arguments and executes the query.

Parameters

start – How many entities from the beginning of the result list should be skipped from the query.
num – How many entities should be returned, if 0 (default) then a reasonable default will be chosen.

Returns

A tuple (list of entities, total entity count). If inappropriate URL arguments are given, we return an empty set of results and 0 for the entity count.

get_key_values(entities) source

Returns the union of key names used by the given list of entities.

We return the union as a dictionary mapping the key names to a sample value from one of the entities for the key name.

num() source: Returns the sanitized “num” argument from the URL.

redirect_with_message(message) source: Redirect to the ‘next’ url with message added as the msg parameter.

start() source: Returns the santized “start” argument from the URL.

class google.appengine.ext.admin.DatastoreStatsHandler source
