This is done for efficiency reasons and to make it less likely to encounter memory leaks with badly written WSGI middlewares. The downside is that if you are using streamed responses, the generator cannot access request bound information any more. This function however can help you keep the context around for longer:: from flask import stream_with_context, request, Response @app.route('/stream') def streamed_response(): @stream_with_context def generate(): yield 'Hello ' yield request.args['name'] yield '!' return Response(generate()) Alternatively it can also be used around a specific generator:: from flask import stream_with_context, request, Response @app.route('/stream') def streamed_response(): def generate(): yield 'Hello ' yield request.args['name'] yield '!' return Response(stream_with_context(generate())) .. versionadded:: 0.9 argskwargsrc*|i|}t|SN)stream_with_context)r.r/genr,s r decoratorz&stream_with_context..decoratorls'88C&s+ +rc3Ktj}| td|5d Ed{tdrj  dddy7*#tdrj wwxYw#1swYyxYww)Nz\Attempted to stream with context but there was no context in the first place to keep around.close)r top RuntimeErrorhasattrr6)ctxr3s r generatorz&stream_with_context..generatorrs $$ ;J  J  3(IIK 3(IIK) sB B A=AAAA= B AA::A==BB )iter TypeErrortAnyr Generatornext)r,r4r; wrapped_gr3s` @rr2r2BsL@() q{{ 4 IO I @ ,QUU ,aee , ,i)>?? @s 9A BBr.rc~|stjSt|dk(r|d}tj|S)aySometimes it is necessary to set additional headers in a view. Because views do not have to return response objects but can return a value that is converted into a response object by Flask itself, it becomes tricky to add headers to it. This function can be called instead of using a return and you will get a response object which you can use to attach headers. If view looked like this and you want to add a new header:: def index(): return render_template('index.html', foo=42) You can now do something like this:: def index(): response = make_response(render_template('index.html', foo=42)) response.headers['X-Parachutes'] = 'parachutes are cool' return response This function accepts the very same arguments you can return from a view function. This for example creates a response with a 404 error code:: response = make_response(render_template('not_found.html'), 404) The other use case of this function is to force the return value of a view function into a response which is helpful with view decorators:: response = make_response(view_function()) response.headers['X-Parachutes'] = 'parachutes are cool' Internally this function does the following things: - if no arguments are passed, it creates a new response argument - if one argument is passed, :meth:`flask.Flask.make_response` is invoked with it. - if more than one argument is passed, the arguments are passed to the :meth:`flask.Flask.make_response` function as tuple. .. versionadded:: 0.6 r r)rresponse_classlen make_response)r.s rrFrFs<T ))++ 4yA~Aw  $ $T **rendpointvaluesc Dtj}tj}| td|E|j}t j }|dddk(r|||}n|dd}|jdd}n+|j}| td|jdd}|jd d}|jd d}|jd d} |jj||d} | |s td |j} | |_ |j|||| } | | |_ || dt|z } | S#| | |_ wwxYw#t$r;} ||d<||d <||d <| |d <|jj| ||cYd} ~ Sd} ~ wwxYw)aYGenerates a URL to the given endpoint with the method provided. Variable arguments that are unknown to the target endpoint are appended to the generated URL as query arguments. If the value of a query argument is ``None``, the whole pair is skipped. In case blueprints are active you can shortcut references to the same blueprint by prefixing the local endpoint with a dot (``.``). This will reference the index function local to the current blueprint:: url_for('.index') See :ref:`url-building`. Configuration values ``APPLICATION_ROOT`` and ``SERVER_NAME`` are only used when generating URLs outside of a request context. To integrate applications, :class:`Flask` has a hook to intercept URL build errors through :attr:`Flask.url_build_error_handlers`. The `url_for` function results in a :exc:`~werkzeug.routing.BuildError` when the current app does not have a URL for the given endpoint and values. When it does, the :data:`~flask.current_app` calls its :attr:`~Flask.url_build_error_handlers` if it is not ``None``, which can return a string to use as the result of `url_for` (instead of `url_for`'s default to raise the :exc:`~werkzeug.routing.BuildError` exception) or re-raise the exception. An example:: def external_url_handler(error, endpoint, values): "Looks up an external URL when `url_for` cannot build a URL." # This is an example of hooking the build_error_handler. # Here, lookup_url is some utility function you've built # which looks up the endpoint in some external URL registry. url = lookup_url(endpoint, **values) if url is None: # External lookup did not have a URL. # Re-raise the BuildError, in context of original traceback. exc_type, exc_value, tb = sys.exc_info() if exc_value is error: raise exc_type(exc_value).with_traceback(tb) else: raise error # url_for will use this result, instead of raising BuildError. return url app.url_build_error_handlers.append(external_url_handler) Here, `error` is the instance of :exc:`~werkzeug.routing.BuildError`, and `endpoint` and `values` are the arguments passed into `url_for`. Note that this is for building URLs outside the current application, and not for handling 404 NotFound errors. .. versionadded:: 0.10 The `_scheme` parameter was added. .. versionadded:: 0.9 The `_anchor` and `_method` parameters were added. .. versionadded:: 0.9 Calls :meth:`Flask.handle_build_error` on :exc:`~werkzeug.routing.BuildError`. :param endpoint: the endpoint of the URL (name of the function) :param values: the variable arguments of the URL rule :param _external: if set to ``True``, an absolute URL is generated.

Further calls in the same request to the function will return the same messages. By default just the messages are returned, but when `with_categories` is set to ``True``, the return value will be a list of tuples in the form ``(category, message)`` instead. Filter the flashed messages to one or more categories by providing those categories in `category_filter`. This allows rendering categories in separate html blocks. The `with_categories` and `category_filter` arguments are distinct: * `with_categories` controls whether categories are returned with message text (``True`` gives a tuple, where ``False`` gives just the message text). * `category_filter` filters the messages down to only those matching the provided categories. See :doc:`/patterns/flashing` for examples. .. versionchanged:: 0.3 `with_categories` parameter added. .. versionchanged:: 0.9 `category_filter` parameter added. :param with_categories: set to ``True`` to also receive categories. :param category_filter: filter of categories to limit return values.
