How to handle pagination in django templates and views?
I used bootstrap pagination in my templates. My productlist.html looks like this: <div> {% for i in products %} {% if i.is_published %} <div class="thumbnail"> <a href="{{ i.get_absolute_url }}"><img src="{{ i.thumb_url }}" alt="sample"/></a> <a href="{{ i.get_absolute_url }}"><p class="Content">{{ i.description }}</p></a> </div> <nav class="text-center"> <!-- Add class .pagination-lg for larger blocks or .pagination-sm for smaller blocks--> {% if contacts.has_other_pages %} <ul class="pagination"> {% if contacts.has_previous %} <li> <a href="?page={{ contacts.previous_page_number }}" aria-label="Previous"> <span aria-hidden="true">&laquo;</span> </a> </li> {% else %} <li class="page-item disabled"> <a class="page-link" aria-label="Previous"> <span aria-hidden="true">&laquo;</span> </a> </li> {% endif %} {% for i in page_range %} {% if contacts.number == i %} <li class="active"><a class="page_link" href="#">{{ i }} <span class="sr-only">(current)</span></a></li> {% else %} <li><a class="page_link" href="?page={{ i }}">{{ i }}</a></li> {% endif %} {% endfor %} {% if contacts.has_next %} <li> <a href="?page={{ contacts.next_page_number }}" aria-label="Next"> <span aria-hidden="true">&raquo;</span> </a> </li> {% else %} <li class="page-item disabled"> <a aria-label="Next"> <span aria-hidden="true">&raquo;</span> </a> </li> {% endif %} </ul> {% endif %} </nav> In my views: def product_list(request, category_slug=None): category = None products = Product.objects.filter(is_published=True) *** *** if category_slug: category = get_object_or_404(Category, slug=category_slug) products = products.filter(category=category) *** *** paginator = Paginator(products, 5) page = request.GET.get('page') num_pages = paginator.num_pages try: contacts = paginator.page(page) … -

Django display context variable (message) in template using .as_html
I am using some forms from django-graphos, and in order to draw the grpah, in the view def view(): make_your_data_somehow = [ [dataHeaders], [data1], [data2], etc… ] data_source = SimpleDataSource(data=make_your_data_somehow) your_chart = ChartType(data_source) return render(request, 'dataViewer.html', { 'chart' : your_chart, }) and in the template you would: <div> {{chart.as_html}} </div> <!-- the `chart` itself is a graphos object i think, it prints '<graphos.renderers.gchart.LineChart object at 0x107ecb190>' without `.as_html`--> In my case I need to have a certain data structure (more than one dataN in the example above). I can correctly detect if the data structure is correct in the view, but I am trying to avoid making an entirely new template for just one case (or restructuring for a template include). How do I make a variable have text that will be processed when called as variable.as_html in the view as actual text. I have tried: chart = 'Need more than one data to display Graph' chart = None a few others I can't retrace :\ but they all display nothing, unless I remove the .as_html in the template, which then would make displaying the graph non-existent. The only thing I know to do is to declare them as None … -
editing a slug post in django
I have an application where user create posts and can view them. the problem I face is with the edit button and how to make only users who created the post be able to edit their own post or delete them else another user can not. if I enter into the browser url field for example http://127.0.0.1:8000/soko/edit it opens the form field and it is ready to be edited but if I use input button from my template I get the following error Reverse for 'edit' with no arguments not found. 1 pattern(s) tried: ['(?P<slug>[\\w-]+)/edit/$'] below is my views.py def edit(request, slug = None): instance = get_object_or_404(Post, slug = slug) form = PostForm(request.POST or None, request.FILES or None, instance = instance) if form.is_valid(): instance = form.save(commit=False) instance.save() messages.success(request, "Post updated") #redirecting to landing page return HttpResponseRedirect(instance.get_absolute_url()) context = { "title": instance.title, "instance": instance, "form": form, } template = 'edit.html' return render(request, template, context) def delete(request, slug=None): instance = get_object_or_404(Post, slug=slug) instance.delete() messages.success(request, "Post Deleted") return redirect(index) urls.py url(r'^(?P<slug>[\w-]+)/edit/$', views.edit, name='edit'), url(r'^(?P<slug>[\w-]+)/delete/$', views.delete, name='delete'), html <a class="btn btn-default" href="{% url 'posts:edit' %}"></a> futher codes would be supplied on request -
django_rest_swagger using http not https in "try it out" button
I'm using Django Rest Framework with Django Rest Swagger for API documentation. It seems that the "try it out" button always submits http requests, not https requests, even though the browser is https.

Django view not recognizing request

Django Template syntax/tag to filter and check if a related data exists in that model
I'm working on a project with python-3.6.4 and django-2.0.2. For simplicity, I'm explaining the situation in short. Suppose, there are three apps:- "problems", "solve_activities" and "profiles" having three models(mentioned below) inside them. I have a "DetailView" page for each problem. I want to show if the logged in user has solved the problem or not. The django template tag that I wanted to do use was something like this: " {% if user.is_authenticated and problem.solved.objects.all.filter(solver={{user.username}}) %} " Here are the above mentioned files: "problems/models.py": class Problem(models.Model): name = models.CharField(max_length=20) slug = models.SlugField(allow_unicode=True, max_length=100, unique=True) def __str__(self): return self.name def get_absoulte_url(self): return reverse('problems') return reverse('problems:problem_detail', kwargs={'slug':self.slug}) I've used the urlpatterns in 'problems/urls.py' as "path('/', views.ProblemDetail.as_view(), name='problem_detail')". "profiles/models.py"(inherited from auth.models.User): class User(auth.models.User, auth.models.PermissionsMixin): def __str__(self): return self.username "solve_activities/models.py": class Solve(models.Model): problem = models.ForeignKey(Problem, on_delete=models.CASCADE, related_name="solved") solver = models.ForeignKey(User, on_delete=models.CASCADE, related_name="solved") I'm only creating this object when the user solves a problem. Now, my ProblemDetail view on problems/views.py: class ProblemDetail(generic.DetailView): model = Problem template_name = 'problems/problem_detail.html' And the "problems/problem_detail.html" file where I'm facing the complexity basically: <h1>{{problem}}</h1> <h4>Solve Status: {% if user.is_authenticated and problem.solved.objects.all.filter(solver={{user.username}}) %}Solved{% else %}Unsolved{% endif %}</h4> Again, {% if user.is_authenticated and problem.solved.objects.all.filter(solver={{user.username}}) %} this is what I want to do, … -
Django/Celery - SIGSEGV error accessing database
I have a Python-based Django app using the Celery task queue. I need to access my database, which I'm trying to do using the private key (See tasks.py). However, trying to access the database raises a segmentation fault error, and I'm not sure why. When I run this code directly from views.py, that is, I run dummyTask(user_model.id) rather than dummyTask.delay(user_model.id) the tasks runs to completion without any error messages. What could be causing this error with accessing my database? I looked at this question but couldn't find a solution. I'm running Python 3.6, Django 2.0.3 and celery 4.1.0 currently, and am also using db.sqlite3 with redis.

Count True or False (1 or 0) values from database in Django template
I am trying to implement user template view to show how many devices are online and how many are offline. For that instance I am storing in database column 'status' with values of 1 and 0.

Local postgis DB setup for Geodjango
I've been trying to setup my (windows) computer such that I can have a local postgreSQL with PostGIS extension. With this installed I hope to be able to create a project with geodjango locally before putting it in the cloud.

I've tried to follow most of the geodjango information/tutorials online, but can't get it to work. What I've done (mostly followed this: https://docs.djangoproject.com/en/2.0/ref/contrib/gis/install/#windows): Download and install the latest (10.3) PostgreSQL setup from https://www.enterprisedb.com/downloads/postgres-postgresql-downloads After installation I also installed used the Application Stack Builder to install PostGis I've installed OSGeo4W from https://trac.osgeo.org/osgeo4w/ I've created a batch script as described on the geodjango website (https://docs.djangoproject.com/en/2.0/ref/contrib/gis/install/#windows) and ran it as administrator (except for the part where it sets the path to python, cause python was already in there since I've been using python for a while now) I've tried some command in psql shell and I think I've created a database with name: geodjango, username: **** and pass: ****.

Django: setting environmental variables with Supervisor
I'm using Supervisor to run Celery in the background of a Django application however it's not able to access the environmental variables I have set/exported in my virtual environment's postactivate file. I'm working in a local environment and running Ubuntu 16.04 on a Vagrant box. When I start Celery using Supervisor I get a Spawn error with the following exception: django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty I know this question has been asked here before however I've tried many of the solutions and haven't found one that works. I've tried setting supervisor's 'environment' key in supervisord.conf under the supervisord section as follows but I get a "file not found error" when I start Supervisor: [supervisord] ... environment=DJANGO_KEY="key" I've also tried setting the same key in the same file as a django program which Supervisor seems to recognize however it's unable to parse Django's special characters. [program:django] environment=DJANGO_KEY="key" If I set the Django_KEY directly into my settings file everything works. I'm a bit new at all this and it's still a little foggy to me as to how the different programs that run gain access to the file directory, so it's very possible that I'm missing some core concept … -

Calendar in python/django
I am working on a website with weekly votations, but only the first three weeks of the month, so in each instance I have a start_date and end_date field. I'd like to know if there's a way to automitically create these instances based on the current date, for instance: Today it is 6 of March, and votations end tomorrow, so a function should be run (tmrw) that, taking into account this month calendar, would fill in the appropiate dates for the next votations. What calendar do you recommend me, and how shoul I do it? (Never mind the automatically run part, I'll go with celery). Thanks! -
How can I get in post the context_data?
In a CreateView I have the following code: def post(self, request, *args, **kwargs): response = super().post(request, *args, **kwargs) send_confirmation_email() When a form is submited, I want to send an email, but in the email function, I need some data from the context(what was submitted). Also I want this to happen if everything is ok, so also on get_success_url.
