kandi X-RAY | immutabledict Summary
A fork of frozendict, an immutable wrapper around dictionaries. It implements the complete mapping interface and can be used as a drop-in replacement for dictionaries where immutability is desired. The immutabledict constructor mimics dict, and all of the expected interfaces (iter, len, repr, hash, getitem) are provided. Note that an immutabledict does not guarantee the immutability of its values, so the utility of hash method is restricted by usage. The only difference is that the copy() method of immutable takes variable keyword arguments, which will be present as key/value pairs in the new, immutable copy.

I have a webapp using Python, Flask and Flask-Security-Too. When running locally against a deployed database (also in Azure) It's working as intended. When the application is deployed to Azure it also works nicely. However, after a period of time it will start to throw errors like the one below:

app.config["SQLALCHEMY_ENGINE_OPTIONS"] = {"pool_pre_ping": True}
and see if that helps.

QUESTION
hope you are all doing well.
Im working on api project using python and flask. The question I have to ask is, how can I get the values of multiple query string parameter?
The api client is built in PHP, and when a form is submitted, if some of the parameters are multiple
the query string is built like filter[]=1&filter[]=2&filter[]=3...
and so on.
When I dump flask request, it shows something like (filter[], 1), (filter[], 2), (filter[], 3)
, it seems ok, but then when I do request.args.get('filter[]')
it returns only the first item in the args ImmutableDict, filter[]=1
, and I can't access the other values provided.
Any help regarding this issue would be aprreciated. Happy programming!

Answered 2020-Feb-07 at 04:25I've been troubleshooting this today while installing another package as well and it seems there was a new version released today that might be causing the issue.
https://pypi.org/project/Werkzeug/#history
I decided to go back to an earlier version (0.16.1) and it solved my issue. To downgrade:
pip install --upgrade werkzeug==0.16.1
Hope this works for you as well.
