VirtualEnv apache2 server No module named 'django'
I am running a virtual environment for my apache2 server from inside /home/myname/myproject/venv I activate my virtual environment with source venv/bin/activate Running which django-admin Returns the correct file from inside my virtual environment. Running import django django.__file__ Returns /home/myname/myproject/venv/lib/python3.6/site-packages/django/__init__.py Running pip freeze Returns all of my needed packages. I also have my apache2 config file pointing to the venv directory with the python-path argument However, after restarting the server I'm still getting a ModuleNotFoundError for django. What's the issue here? -

Not able to use two models in the same django view
I'm quite new to django, and can't seem to make two models in the same view work. I have tried the guide in the djano docs, but can't seem to be able to use two different models templates in the html. Is it possible that i've misunderstood how the OneToOneField works?

django-rest-framework and http to https redirect
I want to redirect all http requests to https in my django app. The app has also an api through which I make request to database. Those requests are made through http protocol and I want to redirect them to https as well . Below configuration works well with requests made in web browser (http are correctly redirected to https and the website displays). However, the requests through api cause 301 error (Moved Permanently). Am I missing something here? This is my nginx configuration: server { listen 80; server_name myurl.com; return 301 https://$server_name$request_uri; } server { listen 443 ssl; server_name myurl.com; ssl_certificate /path_to_cer; ssl_certificate_key /path_to_key; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; proxy_redirect off; #proxy_buffering off; } Django settings: SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') SESSION_COOKIE_SECURE = True CSRF_COOKIE_SECURE = True -
FloatField returns str object instead of Float in Django
While working on something in Django, I stumbled upon this wierd error (cuz it never happened before). If in a FloatField I saved a float value as string i.e. '245.4' instead of actual float value i.e. 245.4, then on accessing the value it returns back the string instead of float! the reason why abs(modelname.floatfield) threw TypeError today. On research found this old thread in Django's forum (https://code.djangoproject.com/ticket/19565). Is it decided and implemented yet or should I typecast values manually from now on or anyone has a better solution? -

django: custom code integration into django project
Noob here with django. I have the following folder structure for a dhango app, which is inside the main project folder. my_app/ __init__.py admin.py apps.py migrations/ __init__.py models.py tests.py views.py I have a command line python script I wrote to fetch a json file and parse it to displays very specific information. it's using requests library for JSON and data parsing. My question is how do I integrate my script into django app. specifically how to bring the logic of it and to place under which file? My thinking is to create another file and import them into views. and pass them into render function - this may be not the right and django way, but kinda stuck there. Oh and I don't use any DB, the script uses a text file and writes to it as well. -

Why attribute of a dictionary works in template html through connection with codes in view.py ?
I am new to Django, and I am following a tutorial in which he writes something like {%for post in posts %} {{post.author}}in the template html file. He describes that the template responds to the key 'posts'. To my understanding, post is a dictionary according to what he writes in view.py? How does it work? posts = [ { 'author': 'JosephJ', 'title': 'Blog Post1', 'content': 'First post content', 'date_posted': 'August 27, 2018' }, { 'author': 'RogerL', 'title': 'Blog Post2', 'content': 'Second post content', 'date_posted': 'August 28, 2018' } ] def home(request): context = { 'posts': posts } return render(request, 'blog/home.html', context) -

Django - how to access a ForeignKey parent's attribute?
I'm a newbie in Django, and I don't know how to this. I have a model 'Seller': class Seller(models.Model): seller_name = models.CharField(max_length=50) def __str__(self): return self.seller_name and a model 'Item': class Item(models.Model): seller = models.ForeignKey(Seller, on_delete=models.CASCADE) item_name = models.CharField(max_length=100) item_category = models.CharField(max_length=100, choices=ALL_CATEGORIES) item_price = models.FloatField() item_preview = models.ImageField(upload_to='previews/<the seller's name>') def __str__(self): return self.item_name connected via ForeignKey to Seller. In this model, I have an ImageField, and I want it to upload the files to previews/Seller's name directory, but I don't know how to access the Seller's name from Item. Is it possible? Or am I doing something I am not supposed to? Because I couldn't find any similar cases in the internet.
