Django render_to_string Returns NoneType Error
Using Django Pagination I'm trying to do endless pagination using AJAX. I followed the example here: https://www.progerhub.com/tutorial/adding-pagination-with-infinite-scroll-in-django/ My view returns the first page of results just fine, but when I attempt to build the content for the additional pages and return it as JSON using render_to_string I get an error while appending data onto my content variable. error message web_1 | Traceback (most recent call last): ... web_1 | File "/usr/src/django/media/views.py", line 74, in get web_1 | content += render_to_string('media_item.html', {'media': media, }, request=request) ... web_1 | new_obj = func(obj, *arg_vals) web_1 | File "/usr/local/lib/python3.8/site-packages/django/template/defaultfilters.py", line 784, in divisibleby web_1 | return int(value) % int(arg) == 0 web_1 | TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType' models.py class Media(Audit): title = models.CharField( max_length=255) description = models.CharField( max_length=500, blank=True, null=True) poster = ProcessedImageField( blank=True, null=True, format='JPEG', options={'quality': 100}, processors=[ResizeToFill(1000, 1500)], upload_to=get_poster_path) class Meta: ordering = ( 'title', 'year') def __str__(self): return self.title views.py class MediaView(LoginRequiredMixin, JsonMixin, View): def get(self, request, *args, **kwargs): context = self.get_context_data() media = models.Media.objects.filter() page = int(request.GET.get('page', 1)) p = paginator.Paginator(media, 24) # number of media per page # try to get media for the given page try: media_page … -
Docker with venv or without?
I am new in Docker and learning it, and my question is that do I have to use venv in Docker or isn't it important? Because I couldn't configure venv in docker, it gives me an error like cannot import Django activate venv..., I read some answers but couldn't get answer, some people say need to use venv others not important. My DOckerfile FROM python:3.8 #set environment variables ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 RUN python3 -m venv venv #Set work directory WORKDIR /code/ #Install dependencies COPY requirements.txt . RUN . /venv/bin/activate && pip install -r requirements.txt COPY . /code/ If I don't use venv Docker runs fine, but when it comes to install package it gives me warning like WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead:... Can someone explain clearly it? Thanks in advance -

Is it safe to delete a Django QuerySet that may be empty?
Is it safe to attempt to delete a QuerySet that might be empty? In other words, if I am not sure if the name "MJ" exists, is there any functional difference between these 2 approaches? Is either preferred? 1) query = m.objects.filter(name="MJ") if query.exists(): query.get().delete() m.objects.filter(name="MJ").delete() -

Интеграция данных парсера с Django [closed]
Я хочу сделать сайт, на котором можно будет посмотреть информацию о разных вузах. У меня готовы парсеры, но я не понимаю, как можно правильно интегрировать парсеры в Django приложение... Когда я искал информацию по этому поводу, одним рекомендовали использовать django-admin команды, другим использовать парсеры. Я не понимаю, что использовать лучше, у чего какие плюсы и что стоит в итоге выбрать? На данный момент у меня парсеры заливают информацию в стороннюю бд и через класс вытягивается в html форму. Не думаю, что это правильное решение... -

Django Haystack select which fields to search
Suppose I have a Person model looking like this: class Person(models.Model): title = models.CharField(max_length=300, blank=True, null=True) first_name = models.CharField(max_length=300, blank=True, null=True) last_name = models.CharField(max_length=300, blank=False, null=False) And a Haystack search index like this: class NoteIndex(indexes.SearchIndex, indexes.Indexable): text = indexes.CharField(document=True, use_template=True) title = indexes.CharField(model_attr='title') first_name = indexes.CharField(model_attr='first_name') last_name = indexes.CharField(model_attr='last_name') Say the template includes all three fields(firstname, lastname and title). If users should be able to choose in which fields to search for, do I need to build seperate indices for all possible permutations? Or can I narrow down the search to one or two of the three fields? If so how? I know that I am able to filter SearchQuerySets using .filter(). SearchQuerySet().filter(first_name='foo') But this filters the set for exact values. Even __icontains is limited to one field filtering. -

AttributeError: 'Post' object has no attribute 'post_image'
I am using DRF and Django(4.0) to make posts in a Instagram Clone. The models of the following are available below.

However I am getting the following error when I do a get request. Got AttributeError when attempting to get a value for field 'post_image' on serializer 'PostViewSerializer'. The serializer field might be named incorrectly and not match any attribute or key on the `Post` instance. Original exception text was: 'Post' object has no attribute 'post_image'.

Understanding Model.from_db() in Django
I was reading Django Official Doc for Model, it reads: classmethod Model.from_db(db, field_names, values)¶ The from_db() method can be used to customize model instance creation when loading from the database. The db argument contains the database alias for the database the model is loaded from, field_names contains the names of all loaded fields, and values contains the loaded values for each field in field_names. The field_names are in the same order as the values. If all of the model’s fields are present, then values are guaranteed to be in the order __init__() expects them. That is, the instance can be created by cls(*values). If any fields are deferred, they won’t appear in field_names. In that case, assign a value of django.db.models.DEFERRED to each of the missing fields. I am completely lost when reading above. 1st perception: "when loading from the database": for me, loading means reading / retrieving data from database, which means the model instance already exists or is created and stored in DB. 2nd perception: "be used to customize model instance creation", as well as the 2nd paragraph all makes me feel that this from_db() is for model instance creation, which conflicts with my 1st perception. Q: Can … -

Why the session data isn't flush when I logout?
Working on a simple project using Django 3.8, I have recently added a login register form to the application. The login register works very well but when I log out from the account the session isn't flushed, and that means that I can still login without entering the credentials as normally would it be. To create the login/register I have used the Django library which is: from django.contrib.auth import authenticate, login, logout, and in the documentation, it says that the logout(request) function deletes the session by itself: https://docs.djangoproject.com/en/4.0/topics/auth/default/ but actually, the session isn't flushed after I log out. I also check the process in Application, Cookies in the inspect. To understand better of what I have done, will show the code below: views.py from django.http.response import HttpResponse from django.shortcuts import render, redirect from django.utils import timezone from django.db.models import Count from django.contrib.auth.forms import UserCreationForm from django.contrib.auth import authenticate, login, logout from django.contrib.auth.decorators import login_required from django.http import HttpResponse from django.contrib import messages from .models import * from .models import __str__ from .forms import CreateUserForm # Create your views here. @login_required(login_url='login/') def home(request): user = request.user count_item = todo.objects.count() all_items = todo.objects.filter(user=request.user).order_by("created") context = {'all_items': all_items, 'count_item':count_item} return render(request, 'html/home.html', context) …
