django-elasticsearch-dsl Mapping for completion suggest field not working
This problem has been driving me crazy for days with not solution.

Django DATE_FORMAT weekday name
I want to format date object in Django. Specifically, I want to use DATE_FORMAT in settings.py. Using Django Documentation, I set it as: DATE_FORMAT = 'l, m F Y'. Lowercase l means weekday name. In the template I use {{ value|date:"DATE_FORMAT" }}, but it never renders the weekday name. If I do the: {{ value|date:"l, m F Y" }}, I get the results expected. Are there any limitations which built-in date filters are allowed in settings.py? Thank you! -

azure web app for containers uWSGI listen queue of socket full
My app running in a docker container on Azure Webapps for Containers (linux). I found out my server is getting error when listening queue increases. log: uWSGI listen queue of socket "127.0.0.1:37400" (fd: 3) full !!! **(101/100)** I have added '''--listen 4096''' option to increase the queue. but my server still throws error. log: uWSGI listen queue of socket "127.0.0.1:37400" (fd: 3) full !!! **(129/128)** some reference says need to increase net.core.somaxconn but I couldn't increase it. log: sysctl: error: 'net.core.somaxconn' is an unknown key Any idea what i am missing? Thanks
