It is passed the name of the module or package of the application. Once it is created it will act as a central registry for the view functions, the URL rules, template configuration and much more. The name of the package is used to resolve resources from inside the package or the folder the module is contained in depending on if the package parameter resolves to an actual python package (a folder with an `__init__.py` file inside) or a standard module (just a `.py` file). For more information about resource loading, see :func:`open_resource`. Usually you create a :class:`Flask` instance in your main module or in the `__init__.py` file of your package like this:: from flask import Flask app = Flask(__name__) .. admonition:: About the First Parameter The idea of the first parameter is to give Flask an idea what belongs to your application. This name is used to find resources on the file system, can be used by extensions to improve debugging information and a lot more. So it's important what you provide there. If you are using a single module, `__name__` is always the correct value. If you however are using a package, it's usually recommended to hardcode the name of your package there. For example if your application is defined in `yourapplication/app.py` you should create it with one of the two versions below:: app = Flask('yourapplication') app = Flask(__name__.split('.')[0]) Why is that? The application will work even with `__name__`, thanks to how resources are looked up. However it will make debugging more painful. Certain extensions can make assumptions based on the import name of your application. For example the Flask-SQLAlchemy extension will look for the code in your application that triggered an SQL query in debug mode. If the import name is not properly set up, that debugging information is lost. (For example it would only pick up SQL queries in `yourapplication.app` and not `yourapplication.views.frontend`) .. versionadded:: 0.7 The `static_url_path`, `static_folder`, and `template_folder` parameters were added. .. versionadded:: 0.8 The `instance_path` and `instance_relative_config` parameters were added. :param import_name: the name of the application package :param static_url_path: can be used to specify a different path for the static files on the web. Defaults to the name of the `static_folder` folder. :param static_folder: the folder with static files that should be served at `static_url_path`. Defaults to the ``'static'`` folder in the root path of the application. :param template_folder: the folder that contains the templates that should be used by the application. Defaults to ``'templates'`` folder in the root path of the application. :param instance_path: An alternative instance path for the application. By default the folder ``'instance'`` next to the package or module is assumed to be the instance path. :param instance_relative_config: if set to `True` relative filenames for loading the config are assumed to be relative to the instance path instead of the application root. c C s | j S( N( t app_ctx_globals_class( R4 ( ( s8 /opt/imh-python/lib/python2.7/site-packages/flask/app.pyt _get_request_globals_class� s c C s- d d l m } | t d � � | | _ d S( Ni����( t warnsC request_globals_class attribute is now called app_ctx_globals_class( t warningsR= t DeprecationWarningR; ( R4 R/ R= ( ( s8 /opt/imh-python/lib/python2.7/site-packages/flask/app.pyt _set_request_globals_class� s t DEBUGt TESTINGt SECRET_KEYt SESSION_COOKIE_NAMEt PERMANENT_SESSION_LIFETIMEt get_convertert USE_X_SENDFILEt LOGGER_NAMEt -iP s s7 %(levelname)s in %(module)s [%(pathname)s:%(lineno)d]: s %(message)s t extensionss jinja2.ext.autoescapes jinja2.ext.with_t PROPAGATE_EXCEPTIONSt PRESERVE_CONTEXT_ON_EXCEPTIONt daysi t SERVER_NAMEt APPLICATION_ROOTR t SESSION_COOKIE_DOMAINt SESSION_COOKIE_PATHt SESSION_COOKIE_HTTPONLYt SESSION_COOKIE_SECUREt MAX_CONTENT_LENGTHi i< t SEND_FILE_MAX_AGE_DEFAULTt TRAP_BAD_REQUEST_ERRORSt TRAP_HTTP_EXCEPTIONSt httpt PREFERRED_URL_SCHEMEt JSON_AS_ASCIIt JSON_SORT_KEYSt JSONIFY_PRETTYPRINT_REGULARt statict templatesc C s� t j | | d | �| d k rQ d d l m } | t d � d d �| } n | d k ri | | _ n | d k r� | | _ n | d k r� | j � } n! t j j | � s� t d � � n | | _ | j | � | _ d | _ | j | _ i | _ i | _ i | j d 6| _ g | _ i | _ g | _ i | _ i | _ g | _ i | _ i | _ i t g d 6| _ i | _ i | _! t" � | _# t$ | _% t& � | _' | j( r�| j) | j d d d d | j* �n d S( Nt template_folderi����( R= s) static_path is now called static_url_patht stackleveli sX If an instance path is provided it must be absolute.

If the :attr:`debug` flag is set the server will automatically reload for code changes and show a debugger in case an exception happened. If you want to run the application in debug mode, but disable the code execution on the interactive debugger, you can pass ``use_evalex=False`` as parameter. This will keep the debugger's traceback screen active, but disable code execution. .. admonition:: Keep in Mind Flask will suppress any server error with a generic error page unless it is in debug mode. As such to enable just the interactive debugger without the code reloading, you have to invoke :meth:`run` with ``debug=True`` and ``use_reloader=False``. Setting ``use_debugger`` to `True` without being in debug mode won't catch any exceptions because there won't be any to catch. .. versionchanged:: 0.10 The default port is now picked from the ``SERVER_NAME`` variable. :param host: the hostname to listen on. Set this to ``'0.0.0.0'`` to have the server available externally as well. Defaults to ``'127.0.0.1'``. :param port: the port of the webserver. Defaults to ``5000`` or the port defined in the ``SERVER_NAME`` config variable if present. :param debug: if given, enable or disable debug mode.

For information about unit testing head over to :ref:`testing`. Note that if you are testing for assertions or exceptions in your application code, you must set ``app.testing = True`` in order for the exceptions to propagate to the test client. Otherwise, the exception will be handled by the application (not visible to the test client) and the only indication of an AssertionError or other exception will be a 500 status code response to the test client. See the :attr:`testing` attribute. For example:: app.testing = True client = app.test_client() The test client can be used in a `with` block to defer the closing down of the context until the end of the `with` block. This is useful if you want to access the context locals for testing:: with app.test_client() as c: rv = c.get('/?vodka=42') assert request.args['vodka'] == '42' See :class:`~flask.testing.FlaskClient` for more information. .. versionchanged:: 0.4 added support for `with` block usage for the client. .. versionadded:: 0.7 The `use_cookies` parameter was added as well as the ability to override the client to be used by setting the :attr:`test_client_class` attribute. i����( t FlaskClientt use_cookiesN( t test_client_classRd t flask.testingR� t response_class( R4 R� t cls( ( s8 /opt/imh-python/lib/python2.7/site-packages/flask/app.pyt test_client s ! c C s | j j | | � S( sP Creates or opens a new session.
