find out how api authenticate users Django
I am working with a MySQL database managed by a django app and an api on which I do not have access. I will find out later how the api works but I need to make this functionality now for a presentation. The passwords in the database are stored this way $2a$10$rA59QU2GsWR4v6hugdYhruxY0bgZYVLv6ncxRe3BiDJMEpK0A0huW - when user registers from the legacy app. From my django app, users register and passwords are stored this way $2b$12$koykshnEpT39MgciBp4FGepw.LnbHt2Kmqbfm4TSipX6FAVRVKdjW. Django app can authenticate and passwords are validated ok no matter how many iterations are there and prefix $2b$ or $2a$. But recently in order to access an api feature I've needed to log in the user from the api side, so if I authenticate user using dajngo's generated password hash, the api does not succeed to authenticate. The question is, What do I need to tackle in order to make it work? I have tried to change iterations from 12 to 10, did not work. Now I want to change the prefix to 2a, not sure if it will work but anyway. Next I found that the password can be hashed with or without null terminator -> correct me if Im wrong but I need to … -

How do I find the class that RelatedManager is managing when the QuerySet is empty?
I have two models that are related. From the object of one, I want to get the class name of the other. Currently, I'm doing it this way: associated_model = getattr(object_specific, associated_model_str) associated_model_instance = associated_model.all().first() if associated_model_instance: associated_model_name = associated_model_instance.__class__.__name__ In this case, object_specific is an object of a model. associated_model_str is the name of the attribute in that model that has a reference to the second model. When I get the attribute into associated_model, this variable contain the RelatedManager for the second model. If I do .all().first() I will get an object from that model, from where I can get the class name by checking the attribute .__class__.__name__. The problem is that sometimes I don't have any instances of the second model in the database associated to the instance of the first model. In other words, the .all() comes empty. So I don't have an instance of the second class to get the class name. How can I get that class name directly from the RelatedManager? -
how to prevent new element being appended repeatedly in javascript function?

Is there any way that i could possibly pass the variable in smartly as it will not just append repeatedly to the existing address? I have tried to do it like const url = window.location window.location.replace(url.hostname + url.pathname + url.search + "&name=" + device.value) But it doesn't solve the problem. -

What is the equivalent of " LIKE concat('%', ?, '%') " in Django?
I need to convert MariaDB raw queries to Django's default MySQL backend raw queries. MariaDB uses ? for the parameterization and the Django-MySQL connector uses %s instead.

Uploading a canvas (web camera snap) taken on client's side (with javascript) to Django's server side
I am new with Django, and I need to take a snap on the client's side with js [done in 1.] and send it to my server [trial in 2.] so later I can manipulate it on views.py. By now, I can send images to the server (media/images), but only if I use that "Django's button" that is auto-generated through forms/models and views, which forces the user to choose a pic from his computer. The problem is that I need it to be automatized (so the program must "grab" the snap, name it (as snap.jpg, for example), "put it somehow on that button", and upload it). I have been searching and trying for the last 3/4 days, and this was the best I could do... Please take into consideration that I am a newbie...

CommandError: Unable to find a locale path to store translation for file manage.py after adding additional setting COUNTRIES_OVERRIDE
I am trying to translate just one specific country for django-countries and my language (zh-hant) is yet to be translated. I tried to add the example in documentation COUNTRIES_OVERRIDE = { "NZ": _("Middle Earth"), "AU": None, "US": { "names": [ _("United States of America"), _("America"), ], }, } to the end of my settings.py and after that this error occurs: CommandError: Unable to find a locale path to store translations for file manage.py yet reverting this setting is fine.

Create-react app integration with django backend vs babel and webpack pipeline
I've been trying to get up a react and django application. First, I had followed this set of videos here: https://www.youtube.com/watch?v=6c2NqDyxppU&list=PLzMcBGfZo4-kCLWnGmK0jUBmGLaJxvi4j&index=3. There was a bunch of commands that you can see in the description that needed to be run in as well as a lot of copy pasting configuration files. Later, my friend told me that create-react-app existed and would set up everything needed with just one command. I tried it, and it worked really well. However, there were issues with connecting it to django. The files that came out of create-react-app were different to the ones shown in the video and when I tried searching it up, a few solutions said to use npm run build and pass the build folder into django. Running a build takes quite a long time and it is not automatic as it was when I had the webpack and babel system. What am I supposed to do to configure create-react-app so that I can get it to update automatically and get it into django. Some places said that I could edit the config files when I do npm run eject. There is a problem that the package.json files in the tutorial project and …
