Should I deploy my web server with Django's default database?
I'm a noobie to Django and I'm almost at the stage of deploying a web server. I was just having some doubts with Django's database. Currently I'm using the default sqlite3 database to store all the user models as well as the info models. I'm thinking of using AWS to deploy my web sever. So when I get to that stage, should I continue with sqlite or should I switch to AWS's database or something like Firebase. If I continue with sqlite, where and how exactly will the information be stored? And what if I switch to something like PostgreSQL, where will the information be stored and will it be secure/fast (even if I manage to get thousands of users)? Thanks so much, this question might be really basic but I'm super confused. -

Attribute Error: 'function' object has no attribute 'randint'
I'm having trouble with using the random module in my Django app. When I open up a path that should display a random number, I get an error that says: 'function' object has no attribute 'randint'. I've looked this error up, and most people say that this error is because there is a stray random.py file floating around somewhere. Proof there's only one random.py file in my computer, and it is definitely the one that came with the python install. I'm 100% certain, because I uninstalled python 3.8.3 and reinstalled it twice. Here's the code in my views.py file that is calling random.randomint. def entry(request, title): entry = util.get_entry(title) randomNum = random.randint(0, 10) return render( request, "encyclopedia/entry.html", {"entry": entry, "randomNum": randomNum}, ) Then I have an HTML file that displays {{ randomNum }}. When that template gets loaded, I get this error screen. I'm banging my head against the wall trying to figure this out, so any help is greatly appreciated! -

What is the most efficient way to iterate through a dump category tree to store it using django-mptt?
Basically I want to know the most efficient way to recursively iterate through an API result from Global Selling (Mercado Libre) website. They dump the complete category tree at CBT Categories and they recommend to store it offline and update it on a daily basis (or at least frequently), as seen in here. I am currently trying to add all the records to my own Django Model using django-mptt to make it more efficient. However, I am sure there must be a better way to iterate through all the dump. { "id": "CBT1644", "name": "Air Conditioners", "path_from_root": [ { "id": "CBT5726", "name": "Appliances" }, { "id": "CBT385177", "name": "Air Conditioning" }, { "id": "CBT1644", "name": "Air Conditioners" } ], "children_categories": [], .... } I am thinking on starting using the path_from_root and go through each one of them but I don't know how to do it efficiently. Other option is going through all the "leafs" and go up creating every parent (through the children_categories node). I am sure this is more simple than I think but I can't seem to get it. Any help is greatly appreciated. Also I don't want to create a complete overhead every day I run … -
Run a file.py in django
I have a Django project, in which I have already defined the models. I write a file called my_logic.py, which contains custom logics for my app; for example, it SQL-ly queries the relevant data from the database, formats that data, and sends them to an online ML-model to get prediction. I would like to automatically run this file every hour. Is there any way to achieve this? I think the possible answer is cronjob. Thanks -
How to custom message "You do not have permission to perform this action."
Previously I used DRF (django-rest-framework), and also used locale (django translation). But the problem is, I can't modify the message of "You do not have permission to perform this action." into another language, e.g: id. By the way, the translation language from rest_auth and my own application is worked well. And this is my languange settings.py LANGUAGES = ( ('id', 'Indonesia'), ('en', 'English') ) DEFAULT_LANGUAGE = 1 LOCALE_PATHS = ( os.path.join(BASE_DIR, 'locale'), os.path.join(BASE_DIR, 'locale/rest_auth'), ) LANGUAGE_CODE = 'id' USE_I18N = True USE_L10N = True -

Django Variable Used In Model And View
I can find plenty of information on global variables (though I know they should be avoided so am trying to find alternatives) and sharing variables between views, though my case is a little different. At the moment I have the same variable declared in two places, one in a class in models.py (it's fired when a model is created but it's not a model declaration), and it's also passed to a template through a view. What would be my best option for storing this variable? Should it be a global or is there a better alternative? Thank you. -

Switch languaje button not working with urls that contain slugs on Django
I'm new on Django, this is my first real project with this framework on 2.2 version. I've created a switch language button, and it works fine on every page that doesn't have a slug in the URL involved. I've created models for certain products and add them a slug field which is correctly and automatically translated from the product name. Everything works fine as soon as I'm not on a product detail page and I try to change the language. When I do this I get a 404 error because the URL it's not getting translated. For example, if I'm checking a product in English and its URL is mywebsite.com/products/random-slug-of-product and I try to change to Spanish, the URL is the same and it doesn't exist on Spanish version o my page, which gives me a 404 error. My question is, how can I force to obtain the correct URL? Here are a few pieces of my code in case I'm having an error. My switch button <div class="dropdown"> {% for language in LANGUAGES %} {% if language.0 != LANGUAGE_CODE %} <form action="{% url 'set_language' %}" method="post"> {% csrf_token %} <input type="hidden" name="language" value="{{ language.0 }}"> {% trans "Language" %} … -

Send POST request to views.py from base.html template
I'm using django-notifications-hq to display notifications in the top navbar of the website, which happens to be located in the base template file, base.html. I have a small button in the navbar to set notifications to read but I'm having trouble sending the POST request to the views.py. Is there a way to send this POST request from anywhere on the website to a specific function in views.py? I've read about context processors but that only seems to help in opposite scenarios when you want to send data from views to the base template file. Function in views.py I want to send a POST request to from base.html: def mark_all_as_read(request): request.user.notifications.mark_all_as_read() return redirect('home') #ideally, just refresh the page the user is on but I can't figure that out either base.html form I want to send a request from: <ul class="dropdown-grid-menu" id="notice-link"> <a href="{% url 'messages' %}"> {% live_notify_list %} </a> <li> <form method='POST'> {% csrf_token %} <br /><button class="btn btn-sm btn-primary" href="{% url 'mark_all_as_read' %}" type="submit" role="button">Mark Read</button> </form> </li> </ul> Hoping there is an easy solution.
