mod_wsgi - Permission denied - Unable to start Python home
I am attempting to run django on an unmanaged VPS running Ubuntu 20.04. I connected to the freshly installed server, installed Django and Postresql. Apache was already installed. I then installed mod_wsgi. I then attempted to configure my .conf file.

Django REST framework is changing object values when request method is GET
i have problem with (not wanted) objects values setting. I have viewset where serialiser is chosen by request.method. I want to update DateTimeField only WITH POST/PUT method, and then can check this value with GET method but.. after posting new object I got json like this { "datetimefield": "2021-10-26 23:01:53.272194" } and after GET method I got this (for the same object): { "datetimefield": "" } my code: class SomeViewSet(viewsets.ModelViewSet): queryset = SomeModel.objects.all() def get_serializer_class(self): if (self.request.method == 'POST'): return FirstSerializer else: return SecondAppSerializer class FirstSerializer(serializers.HyperlinkedModelSerializer): datetimefield = serializers.SerializerMethodField() def get_datetimefield(self, obj): return str(datetime.today()) class Meta: model = SomeModel fields = ('datetimefield') class SecondSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = SomeObject fields = ('datetimefield') class SomeModel(models.Model): datetimefield = models.CharField(max_length=100) Anyone know how to solve this? -
Django serializers methods
I have model called SecondAddress with fields like street, apartment, number, city. For this model I have serializer second_address - with the same fields. This models and serializer are using in Client and Recipient modelserializer as a basic field but not required, it can be null. In the client and Recipient client I have basic_address and this is required. The idea is that if basic_address fields are incorrect, client must to provide second_address fields. Everything works and for checking the status of second_address field I have folowing serializer: matching_address = serializers.SerializerMethodField() And fucntion: def get_matching_address(self, client): return client.second_address is None If basic_address fields is correct there no needed second_address fields and field matching_address will have True. If second_address is provided matching_address field show False. I would like to create function that if matching_address field is True and second_address fields are provided the data must to be deleted from second_address. And if False need to provide second_address fields. Please help me with this function and method -
RegEx length range not working for Django/Python? (re.error: multiple repeat at position)
I'm trying to add a custom Validator with a regex for a-z, A-Z, 0-9, _ and between 3 and 20 characters. class Validator(validators.RegexValidator): regex = r"^[A-Za-z0-9_]{3,20}+\Z" flags = re.ASCII RegEx works fine when there's no character range i.e. r"^[A-Za-z0-9_]+\Z" And I think {3,20} is the correct way of specifying the length... so I'm not sure why the regex isn't working. I get this error re.error: multiple repeat at position 19 regardless of the string that I'm trying to validate.

Caching in django-pytest
In an API Client Library that supports Django, I am implementing a way for users to configure Django Cache when the API Client gets used in a Django application. How do I test the caching behavior without an actual Django app in the Client Library?

Django LRU_Cache with API Calls
I'm trying to use the Reddit API via PRAW (https://praw.readthedocs.io/en/stable/) with Django, and am thinking of trying to use functools lru_cache decorator to implement some kind of caching so I can cache the results of similar API calls to reduce overall calls being made. I've never done anything like this so I've been mainly following examples of implementing the @lru_cache decorator. I have 3 files that are primarily involved with the API calls / display here. I have: account.html {% extends 'myapp/base.html' %} <h1> {{ name }} </h1> <h3> {{ comment_karma }} </h3> <h5> Top Posts </h5> <table> <tr> <th> Post </th> <th> Subreddit </th> </tr> {% for s in top_submissions %} <tr> <td> {{ s.title }} </td> <td> {{ s.subreddit }} </td> </tr> {% endfor %} </table> views.py from . import reddit reddit = reddit.Reddit() def account_page(): context = reddit.details(request.user.reddit_username) return render(request, 'stats/dashboard.html', context) reddit.py from functools import lru_cache class Reddit: def __init__(self): self.praw = praw.Reddit( client_id = CLIENT_ID, client_secret = CLIENT_SECRET, user_agent = USER_AGENT ) @lru_cache(maxsize = 256) def details(self, redditor): redditor = self.praw.redditor(redditor) overview = { 'name': redditor.name, 'comment_karma': redditor.comment_karma, 'top_submissions': redditor.submissions.top(limit=10), } return overview Here's the problem: when I don't have the lru_cache, then everything works … -

Making all fields in the model formset required in HTML - Django
I have looked at pretty much all questions on Stack Overflow relating to Django Formsets. None of them answer my question in a realistic manner. I have a page that uses an inlineformset_factory. The goal is to have parents add their information and then their students information. I need ALL of the student fields to be required in HTML. So far, only the parent information has the required attribute in HTML. The number of students is passed in as part of the url - example.com/register/3 would be if a parent has 3 students to register. So, if a parent chooses 3 students on the previous page, they would be sent to example.com/register/3 and it would show the parent form with the 3 student forms. THIS IS WORKING. What is not working is making ALL three of the student forms required in the HTML. My view: def homeschoolRegister(request, num): parent_form = ParentInformationForm() StudentFormSet = inlineformset_factory(ParentInformation, StudentInformation, fields=('student_first_name', 'student_last_name', 'grade'), can_delete=False, extra=int(num)) if request.method == 'POST': parent_form_post = ParentInformationForm(request.POST) if parent_form_post.is_valid(): parent = parent_form_post.save(commit=False) parent.save() student_form_post = StudentFormSet(request.POST, instance=parent) if student_form_post.is_valid(): student_form_post.save() try: if int(num) <= 0: return redirect(reverse('home')) if int(num) > 15: return redirect(reverse('home')) context = {'parent_form':parent_form ,'formset':StudentFormSet} return render(request, 'home/home-register.html', … -

Django limit next post and previos post on Detail view to only active
I currently have a model view as such from django.db import models from django.contrib.auth.models import User from django.utils import timezone STATUS = ( (0,"Draft"), (1,"Publish") ) class Post(models.Model): title = models.CharField(max_length=200, unique=True) slug = models.SlugField(max_length=200, unique=True) author = models.ForeignKey( User, on_delete=models.CASCADE, related_name="blog_posts" ) updated_on = models.DateTimeField(auto_now=True) content = models.TextField() created_on = models.DateTimeField(auto_now_add=True) status = models.IntegerField(choices=STATUS, default=0) class Meta: ordering = ["-created_on"] def __str__(self): return self.title def get_absolute_url(self): from django.urls import reverse return reverse("post_detail", kwargs={"slug": str(self.slug)}) and my view looks like so class PostDetail(DetailView): model = Post template_name = 'post_detail.html' and my template looks like so <ul class="text-center"> {% if post.get_previous_by_created_on_active %} <li class="prev"> <a rel="next" href="{{ post.get_previous_by_created_on.get_absolute_url}}"> {{ post.get_previous_by_created_on_active}}</a> </li> {% endif %} {% if post.get_next_by_created_on %} <li class="next"> <a rel="next" href="{{ post.get_next_by_created_on.get_absolute_url}}"> {{ post.get_next_by_created_on}} </a> </li> </ul> Is there any way I can pass the status == 1 to the get_next_by_created_on so it always shows the next active post, not the next draft post? -
