The flask object implements a WSGI application and acts as the centralobject. It is passed the name of the module or package of theapplication. Once it is created it will act as a central registry forthe view functions, the URL rules, template configuration and much more.

A data structure of functions to call to modify the keywordarguments passed to the view function, in the format{scope: [functions]}. The scope key is the name of ablueprint the functions are active for, or None for allrequests.

gh-94199: Remove the ssl.wrap_socket() function, deprecated inPython 3.7: instead, create a ssl.SSLContext object and call itsssl.SSLContext.wrap_socket method. Any package that still usesssl.wrap_socket() is broken and insecure. The function neither sendsa SNI TLS extension nor validates server hostname. Code is subject toCWE-295: ImproperCertificate Validation. Patch by Victor Stinner.

The reverse transformation expression can contain a reference to a PL/SQL function that returns a valid Oracle datatype. For example, you could define a function like the following for a categorical attribute named blood_pressure that has values 'Low', 'Medium' and 'High'.

The model_filter parameter specifies which models to export. You can list the models by name, or you can specify all models that have the same mining function or algorithm. You can query the USER_MINING_MODELS view to list the models in your schema.

The reverse action method works quite simply: it takes your parameters and substitutes them back into the route pattern. In the case of path segments (:foo), the value is encoded before the substitution is done. For regex and wildcard patterns the string is substituted in raw form, since the value may span multiple segments. Make sure you escape those components as desired when passing them to the reverse route, and avoid passing unvalidated user input.

A dictionary with lists of functions that can be used as URL valuepreprocessors. The key None here is used for application widecallbacks, otherwise the key is the name of the blueprint.Each of these functions has the chance to modify the dictionaryof URL values before they are used as the keyword arguments of theview function. For each function registered this one should alsoprovide a url_defaults() function that adds the parametersautomatically again that were removed that way.

A dictionary of all view functions registered. The keys willbe function names which are also used to generate URLs andthe values are the function objects themselves.To register a view function, use the route() decorator. 006ab0faaa
