# pyramid.paster¶

bootstrap(config_uri, request=None, options=None)[source]

Load a WSGI application from the PasteDeploy config file specified by config_uri. The environment will be configured as if it is currently serving request, leaving a natural environment in place to write scripts that can generate URLs and utilize renderers.

This function returns a dictionary with app, root, closer, request, and registry keys. app is the WSGI app loaded (based on the config_uri), root is the traversal root resource of the Pyramid application, and closer is a parameterless callback that may be called when your script is complete (it pops a threadlocal stack).

Note

Most operations within Pyramid expect to be invoked within the context of a WSGI request, thus it's important when loading your application to anchor it when executing scripts and other code that is not normally invoked during active WSGI requests.

Note

For a complex config file containing multiple Pyramid applications, this function will setup the environment under the context of the last-loaded Pyramid application. You may load a specific application yourself by using the lower-level functions pyramid.paster.get_app() and pyramid.scripting.prepare() in conjunction with pyramid.config.global_registries.

config_uri -- specifies the PasteDeploy config file to use for the interactive shell. The format is inifile#name. If the name is left off, main will be assumed.

request -- specified to anchor the script to a given set of WSGI parameters. For example, most people would want to specify the host, scheme and port such that their script will generate URLs in relation to those parameters. A request with default parameters is constructed for you if none is provided. You can mutate the request's environ later to setup a specific host/port/scheme/etc.

options Is passed to get_app for use as variable assignments like {'http_port': 8080} and then use %(http_port)s in the config file.

This function may be used as a context manager to call the closer automatically:

with bootstrap('development.ini') as env:
request = env['request']
# ...


Changed in version 1.8: Added the ability to use the return value as a context manager.

get_app(config_uri, name=None, options=None)[source]

Return the WSGI application named name in the PasteDeploy config file specified by config_uri.

options, if passed, should be a dictionary used as variable assignments like {'http_port': 8080}. This is useful if e.g. %(http_port)s is used in the config file.

If the name is None, this will attempt to parse the name from the config_uri string expecting the format inifile#name. If no name is found, the name will default to "main".

get_appsettings(config_uri, name=None, options=None)[source]

Return a dictionary representing the key/value pairs in an app section within the file represented by config_uri.

options, if passed, should be a dictionary used as variable assignments like {'http_port': 8080}. This is useful if e.g. %(http_port)s is used in the config file.

If the name is None, this will attempt to parse the name from the config_uri string expecting the format inifile#name. If no name is found, the name will default to "main".

setup_logging(config_uri, global_conf=None)[source]

Set up Python logging with the filename specified via config_uri (a string in the form filename#sectionname).

Extra defaults can optionally be specified as a dict in global_conf.
