Django - Custom handler500 not working despite following docs
I followed the docs step-by-step and searched for a solution everywhere but my custom handler500 won't work. I use Django 2.2 with Python 3.8. Here's my urls.py: urlpatterns = [ # some urls ] handler500 = "path.to.my.handler" my handler: def handler500(request, exception=None, *_, **_k): print("yeah I got called") return render(request, "my_template.html", { "exception": exception }) my view: def example_view(request): # I tried all of these return HttpResponseServerError() return HttpResponse(status=500) raise Exception("There was an error") # This just shows: "A server error occurred. Please contact the administrator." in the browser. raise HttpResponseServerError() # This shows the same message as above. a_typo # This typo also shows the same message as above. Why doesn't ANY of these errors show my template? The handler didn't get executed at any time. The print() function never got called. -

Complex Database Query in Django Graph-Structure
I have a django-project with the following model structure. At first I have a graph-structure with nodes and (directed and weighted) edges in the following way: class Node(models.Model): name = models.TextField() class Edge(models.Model): from_node = models.ForeignKey(Node, on_delete=models.DO_NOTHING, related_name='edge_from_node') to_node = models.ForeignKey(Node, on_delete=models.DO_NOTHING, related_name='edge_to_node') costs = models.IntegerField() There also do exists token, whereby a node can be related to multiple tokens but a token can only be related to one node: class Token(models.Model): node = models.ForeignKey(Node, on_delete=models.DO_NOTHING) Additional I have a User object that can own multiple tokens: class MyUser(models.Model): tokens = models.ManyToManyField(Token) I now want to make a database query that for a given TargetNode and MyUser gives the edge with the minimal costs connecting any node, for which MyUser owns a token, with the TargetNode. Let me make a simple example: # we create 4 nodes ... n1 = Node(name="node 1") n2 = Node(name="node 2") n3 = Node(name="node 3") n4 = Node(name="node 4") n1.save() n2.save() n3.save() n4.save() # -.. and create 3 edges e1 = Edge(from_node=n2, to_node=n1, costs=3) e2 = Edge(from_node=n3, to_node=n1, costs=2) e3 = Edge(from_node=n4, to_node=n1, costs=1) e1.save() e2.save() e3.save() # create a user user = MyUser() user.save() # create 2 tokens for the given user to node2 … -
Django error: Instance of 'OneToOneField' has no 'username' member pylint(no-member)
I'm new to Django and I'm learning it throw a youtube tutorial. I'm trying to build a simple Blog but I have some problem that I think could be related to python or django version.

I have a project with Django as back-end. And for the client side I have 4 different sections: Django Admin Panel for super user which renders by Django itself. User Login and Signup section which is rendered by Django-Jinja template system. App admin panel which is a react app Main app front-end which is a react app The structure that I have in my mind is like this: ├── djangoproject │ ├── __init__.py │ ├── settings.py (can be folder) │ ├── urls.py │ └── wsgi.py ├── apps | ├── admin_panel | ├── core | ├── auth | └── ... ├── templates | ├── admin_panel (react) | ├── core (react) | └── auth ├── static └── manage.py I have two questions: 1- should I change the structure of my project (for example bring react folders outside or use frontend folder naming instead of templates?) 2- Is it common (or reasonable) to use git sub module for react apps and only commit build of them in main project? If it is can you give any example or best practice? -

Django Forms with a field based on a Foreign Key
I'm working on a Django Form that add new instances of a Model. The Model itself have a ForeignKey instance. Let's say I wanna record all work shifts of each worker. My Model: class WorkShifts(models.Model): date = models.DateField() check_in = models.TimeField() check_out = models.TimeField() person_name = models.ForeignKey(Worker, on_delete=models.DO_NOTHING) And this is my Form: class AddWorkShifts(forms.ModelForm): date = forms.DateField(initial=datetime.date.today, input_formats=['%d/%m/%Y']) check_in = forms.TimeField() check_out = forms.TimeField() class Meta: model = WorkShifts fields = '__all__' def __init__(self, *args, **kwargs): super(AddWorkShifts, self).__init__(*args, **kwargs) self.fields['date'].widget.attrs['class'] = 'form-control' self.fields['check_in'].widget.attrs['class'] = 'form-control' self.fields['check_out'].widget.attrs['class'] = 'form-control' self.fields['person_name'].widget.attrs['class'] = 'form-control' My HTML code: <form method="POST"> {% csrf_token %} {{ form.date }}<br /> {{ form.check_in }}<br /> {{ form.check_out }}<br /> {{ form.person_name }} <button type="submit">Load</button> </form> And my view: def load_shifts(request): form = AddWorkShifts() if request.method == 'POST': form = AddWorkShifts(request.POST) if form.is_valid: form.save() context = {'form': form} return render(request, 'users/wshifts.html', context) At this point, everything works fine. Notice that form.is_valid doesnt have the () signs. But since I have so many persons (the Foreign Key), I configured a JS Autocomplete plugin (EaseAutoComplete) and redesign the form like this: <form align="center" method="POST"> {% csrf_token %} <input type="text" class="p_name" id="provider-file" /> {{ form.date }}<br /> {{ form.check_in }}<br /> …
