sitemap.xml empty for static urls in Django
I have a Django project and I am trying to create a sitemap for my static urls (no Models). However, when running python manage.py runserver and going to http://127.0.0.1:8000/sitemap.xml, I get it empty: <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"></urlset> My code looks like this: #urls.py from main_app.sitemaps import StaticSitemap sitemaps = { 'static': StaticSitemap(), } urlpatterns = [ ... url(r'^sitemap\.xml$', sitemap, {'sitemaps': sitemaps}), ... ] urlpatterns += i18n_patterns( ... ) and #sitemaps.py from django.contrib.sitemaps import Sitemap from django.urls import reverse class StaticSitemap(Sitemap): priority = 0.5 changefreq = 'weekly' i18n = True def location(self, item): return reverse(item) The documentation shows an example with Models and it modifies the function items; but since I do not have, I am not sure if I am missing something there. What am I doing wrong? -
How to send form data from Angularjs to Django
Good evening. I did the application on the sample from this lesson. Here, using DRF, a list of all added games is displayed on the page.

With js, I'm not very familiar with so far, so I do not know which side to get close to solving the problem. I will be grateful for any help, thanks. -

Sort and paginate a list in Django
Is there any way to sort and paginate a list in Django with Python 3.5.4? The only app that works for me in Python 3.5.4 is webstack-django-sorting which only sorts, and it does not work with the native Django pagination. I tried with: linaro-django-pagination (which webstack-django-sorting recommends) django_filter django_pagination -
factoryboy not working with freezegun

In other words, How to make factoryboy give fake date? (For now, I use MyModelFactory(start_date=date.today()) to create model with fake date.) freezegun version: 0.3.9 factoryboy version: 2.8.1 -
Parse First N Lines of CSV on Model Save
I have a model where users can upload a CSV, however because the files might sometimes be too big, I'd like to parse the first 5 lines of the uploaded CSV and create a new CSV file. This will act as a sample file, that will be smaller and faster to work with later on. This is what my models.py looks like: from django.db import models class Source(models.Model): file = models.FileField() sample = models.FileField(blank=True, null=True) name = models.CharField(max_length=255) def save(self, *args, **kwargs): # I want to parse the 'file' field and write it to 'sample' here super(Source, self).save(*args, **kwargs) def __str__(self): return self.name Basically in the save function of the model, I want to parse the first 5 lines of the file field and take those first 5 lines, create a CSV and upload it to the sample field`. Any ideas on how I can accomplish this? Thanks. -

Django reuse method in views that extend base template, how to?
I have a header.html (call it base.htm if you like) and the typical "n00b learning to create a Django blog" views for post_list, post_edit and post_detail, all of which extend header.html. In the header view/model there is a slogan that is chosen at random from the DB on page load. This works fine on the main page where post_list.html extends header.html. I want to use the call to "propaganda" (my slogans) in each view without repeating it in every method. I tried creating a method that just included the slogan call and called that method from each view-method, but couldn't get it to work. What am I not understanding? header.html > <!DOCTYPE html> <html lang="en"> <head> <title>Ken Dodd's weblogs</title> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1"> <meta name="description" content="Blog site."> <!-- Let's get the static files where we use them, but this could be before the html tag --> {% load staticfiles %} <link rel="stylesheet" href="{% static 'blog/css/bulma.css' %}" type="text/css"/> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css"> </head> <body> <section class="hero is-success is-bold"> <div class="hero-body"> <div class="container"> {% block slogan %} {% for propaganda in propagandas %} <h6>{{ propaganda.slogan }} it's</h6> {% endfor %} {% endblock %} <h1 class="title"> <span class="icon"> <i class="fa fa-home"></i> … -

After changing the database from sqlite3 to MySQL of Django, some part of view doesn't work
After changing the database from sqlite3 to MySQL of Django, some part of view doesn't work. my Schedule model class Schedule(models.model): Trainer = models.ForeignKey(settings.AUTH_USER_MODEL,blank=True,null=True, related_name='schedule', on_delete=models.SET_NULL) title = models.CharField(max_length=12,blank=True) start = models.DateTimeField(null=True, blank=True) views.py search_date1 = request.GET.get('search_date','') #get time search_date= datetime.datetime.strptime(search_date1, '%Y-%m-%d') for f in Fitness_list: for s in f.schedule.all(): #to test print(s.title) #some title print(s.start.month) # 8 print(search_date.year) #2017 print(search_date.month) #8 print(search_date.day) #17 sc = f.schedule.filter(start__month=search_date.month) print(sc) There are schedules with start = 2017-08-17, 2018-08-18, etc.. Also, the search_date.month is 8 But, sc = f.schedule.filter(start__month=search_date.month) results nothing. More odd thing is sc = f.schedule.filter(start__year=search_date.year) works well. Only month and day doesn't work. Before changing the database the views worked well. Why doesn't the code filter correctly? -

Django - Apache Server Error (500) when uploading/saving file
I am attempting to deploy a Django site that has the ability to upload a file and then modify that file. It works 100% on the dev server, however after deploying it with Apache I am running into problems. The Server Error (500) happens on the indicated line in my views.py. What am I doing wrong?

Docker: Access container with python class instance via django application
I am a newbie in docker and ran into a problem that deals with the communication between docker containers: I want to build a docker container that runs an instance of a python class and access this instance via my django application inside my web container.

dynamically load data in django modal for each table cell
Okay I have tried asking this question before but I haven't gotten much help and I think its because I've been framing it the wrong way. So I'm going to give it one more try. Please bear with me as I am still a pretty novice developer. So here is my problem: I am passing data from the view into the template as context which is being populated into a table for viewing. To make it more consolidated and easier to view I am truncating the data in the table. However, to give the user full access to the data I want to display the full data in modal popup window. However, the modal is only loading data for the first row in the table and displaying that for every other row in the table. Here is my template html: {% if data %} {% for key, value in data %} <tr> <td scope="row">{{ forloop.counter }}.</td> <td> <div id="popup"> <p class="citation" data-hover="{{ value.2 }}">{{ value.1 }} <img src='{% static "img/expand-icon2.png" %}' id="expand"></p> <a class="article" target="_blank" href={{ value.3 }}>{{ value.2 }}</a> </div> </td> {% if value.4 %} <td class='test'>{{ value.4 }}<a href='#' id="trigger_{{ forloop.counter }}"><img src='{% static "img/expand-icon2.png" %}' id="expand"></a> {% … -
Paginator Mixin unknown inputs?
I'm just starting with Django so I have a lot of questions. I've built a Mixin to paginate a GCBV (ListView): class PageLinksMixin: page_kwarg = 'page' def _page_urls(self, page_number): return "?{pkw}={n}".format(pkw=self.page_kwarg, n=page_number) def previous_page(self, page): if page.has_previous(): return self._page_urls(page.previous_page_number()) return None def next_page(self, page): if page.has_next(): return self._page_urls(page.next_page_number()) return None def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) page = context.get('page_obj') if page is not None: context.update({'previous_page_url': self.previous_page(page), 'next_page_url': self.next_page(page)}) return context Everything seems to work. But I can simply not see where some of the inputs for functions were created. Especially "page", "page_number". With a CBV it would be necessary to declare: page = paginator.page(page_number) But in the GCBV this is apparently unnecessary which means the attribute is created somewhere and later inherited. For the ListView there is a function def paginate_queryset but in there page is only declared in a local scope not a global scope. Can somebody explain this to me? I'm really confused and trying to figure this out for a while now. This is the View: class TagList(PageLinksMixin, ListView): template_name = 'organizer/tag_list.html' paginate_by = 5 model = Tag -

Django: ValidationError using is_authenticated and logout when authenticating from an external source
I am currently building a Django application that gets all its data from an external source (via HTTP). I therefore do not want to use my own database. I have already implemented my own user and remote user backend as per the solution stated in this SO question: Django users and authentication from external source. I am using signed cookies for storing sessions. After implementing the above stated, I was able to login without any errors. However, on checking whether a user is authenticated in a template (or when trying to log him out in a view), I receive an error: ValidationError at /products/ ["'None' value must be an integer."] at the line in the template {% if user.is_authenticated %} where request.user is passed as a template variable user in the corresponding view (I know I shouldn't do that, it's just temporary).

Django Authentication and Login Issue with Class Based Views

Here's the code: in forms.py the first form called UserForm is used to sign up users, the second form called LoginForm is used to log in users. from django.contrib.auth.models import User from django import forms class UserForm(forms.ModelForm): password = forms.CharField(widget=forms.PasswordInput) class Meta: model = User fields = ['first_name', 'last_name', 'username', 'email', 'password'] class LoginForm(forms.ModelForm): password = forms.CharField(widget=forms.PasswordInput) class Meta: model = User fields = ['username', 'email', 'password'] in views.py from django.shortcuts import render, get_object_or_404, redirect from .models import Step, Cycle, Program, MotorSetting, GeneralSetting from django.views import generic from django.views.generic.edit import CreateView, UpdateView, DeleteView from django.core.urlresolvers import reverse_lazy from django.contrib.auth import authenticate, login from django.views.generic import View from .forms import UserForm from .forms import LoginForm class UserFormView(View): form_class = UserForm template_name = 'programs/registration_form.html' # display blank form def get(self, request): form = self.form_class(None) return render(request, self.template_name, {'form': form}) #process form data def post(self, request): form = self.form_class(request.POST) if form.is_valid(): #storing the data but NOT SAVING them to db yet user = form.save(commit=False) #cleaning and normalizing data username = form.cleaned_data['username'] password = form.cleaned_data['password'] … -
How to overriding model save function when using factory boy?
I'm using Factory Boy for testing a Django project and I've run into an issue while testing a model for which I've overridden the save method. The model: class Profile(models.Model): active = models.BooleanField() user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE, related_name='profiles') department = models.ForeignKey(Department, null=True, blank=True) category_at_start = models.ForeignKey(Category) role = models.ForeignKey(Role) series = models.ForeignKey(Series, null=True, blank=True) status = models.ForeignKey('Status', Status) def save(self, *args, **kwargs): super(Profile, self).save(*args, **kwargs) active_roles = [] active_status = [] for profile in Profile.objects.filter(user=self.user): if profile.active: active_roles.append(profile.role.code) active_status.append(profile.status.name) self.user.current_role = '/'.join(set(active_roles)) if 'Training' in active_status: self.user.current_status = 'Training' elif 'Certified' in active_status: self.user.current_status = 'Certified' else: self.user.current_status = '/'.join(set(active_status)) self.user.save() super(Profile, self).save(*args, **kwargs) ### <-- seems to be the issue. The factory: class ProfileFactory(f.django.DjangoModelFactory): class Meta: model = models.Profile active = f.Faker('boolean') user = f.SubFactory(UserFactory) department = f.SubFactory(DepartmentFactory) category_at_start = f.SubFactory(CategoryFactory) role = f.SubFactory(RoleFactory) series = f.SubFactory(SeriesFactory) status = f.SubFactory(StatusFactory) The test: class ProfileTest(TestCase): def test_profile_creation(self): o = factories.ProfileFactory() self.assertTrue(isinstance(o, models.Profile)) When I run the tests, I get the following error: django.db.utils.IntegrityError: UNIQUE constraint failed: simtrack_profile.id If I comment out the last last/second 'super' statement in the Profile save method the tests pass. I wonder if this statement is trying to create the profile again with the same ID? …
