Deploying in production gunicorn + nginx with domain
I'm new to development and my trying to deploy my django app with gunicorn and nginx.

Using both Django template and React
Hi guys I’m trying to bulid a website which django works as an rest-api and react works as a front side. I manage to do the whole thing just fine and about to deploy it using aws. But there is one thing I couldn’t really get. Inside my django project I have an app that uses only django template to render things to front. And other apps are working only as apis to get and post things via react. Is it possible to deploy this kind of structure without any special options? I searched internet for a while but I couldn’t really find an example that fits my situation. Thanks! -

Django channels - disconnect WebSocket from server side when token expires or gets invalid
I searched about this topic, specifically for Django, but i did not find any applicable solution. Namely, when i use a JWT as a query parameter to authenticate the user while opening a socket connection, the problem i'm thinking of is that the connection can be open for a long time which can exceed the validity of the token. The token can expire or even get invalid if some data changes. If someone steals the token which is expired, he can't really do anything with it because he cannot establish a new socket connection, so i assume this is not a big deal (maybe i'm wrong). The validity of the token on the data side is a bit different. If i used a data part to define the channel name, and then exactly that information changes, the old socket connection will receive the old data even when it should not. For example, if i used users company name for the channel name, and then the admin changes users company, while the old socket connection is still open, the user will still receive data from the old company until the old connection is disconnected and new one established. So i would … -

Utilizar "range" en filterset_fields de django-filters en DRF
estoy intentando traer un rango de un valor y no encuentro ejemplos de como usarlo en la consulta por postman. Por otro lado para probar que el campo funciona para la búsqueda hice una consulta con "exact" y tampoco me esta tomando el campo, por lo que pienso que en realidad el inconveniente está en el campo que llamo. Si bien este campo esta en el modelo, el valor del mismo lo obtengo des un método en el serializer. Como podría yo filtrar por este campo si el valor lo obtengo recién en la respuesta? paso el filtro en la view y el serializer ** filtrar por este campo** filterset_fields = { 'ppv': ['range'] } **campo en el serializer** ppv = serializers.SerializerMethodField(read_only=True) -
