How to raise exceptions in Django view based in ORM exceptions
Instead of doing, for example this: views.py: my_noob_way(request): object = Object.objects.filter(name=request.POST.get('name', None)) if not object: Object.objects.create(name=request.POST.get('name', None)) data = {'success': True, 'message': 'Object successfully created.'} else: data = {'success': False, 'message': 'Object already exists.'} return JsonResponse(data) Instead of doing this, I want to avoid the filter line (extra garbage query) and just performing a create inside a try and catch the possible duplication exception with except. How can I make this? I don't know what to put after except: (Too broad exception clause). -
Nginx try_files not working with domain that appends trailing slash
I have a dockerised Django app where nginx uses proxy_pass to send requests to the Django backend. I am looking to pre-publish certain pages that dont change often so Django doesnt have to deal with them. I am trying to use try_files to check if that page exists locally and pass to Django if not. Our URL structure requires that all URLs end with a forward slash and we dont use file type suffixes e.g. a page might be www.example.com/hello/. This means the $uri param in nginx in this instance is /hello/ and when try_files looks at that it is expecting a directory due to the trailing slash. If I have a directory with a list of files how do I get try_files to look at them without re-writing the URL to remove the slash as Django requires it? My nginx conf is below. server { listen 443 ssl http2 default_server; listen [::]:443 ssl http2 default_server; server_name example.com; root /home/testuser/example; location / { try_files $uri uri/ @site_root; } location @site_root { proxy_pass http://127.0.0.1:12345; } } If I have a file "hello" at /home/testuser/example/hello and call https://www.example.com/hello/ how can I get it to load the file correctly?

Session variable set before request is not accessible in Django view during tests
I need to store a kind of state between HTTP requests. Because I don't use the JS frontend, I decided to use session variables stored in cookies. My session settings look like below: SESSION_ENGINE = "django.contrib.sessions.backends.signed_cookies" SESSION_COOKIE_HTTPONLY = False I need a function to easily manipulate one session variable. Because this functionality is quite simple, I decided to exceptionally use function-based view: def set_category_filter(request, pk): if pk == 0: if 'filter_category_id' in request.session: # this is False during unit testing, but it's ok in a normal app run del request.session['filter_category_id'] else: get_object_or_404(Category, pk=pk, user=request.user) request.session['filter_category_id'] = pk return redirect('index') The problem is I cannot test case when I want to unset this session variable. Suppose the session variable filter_category_id is set and I want to reset it. When I do this in my browser, everything works okay. When I try to do this via Django TestCase, it fails, because this session variable is not passed to request! class SetCategoryFilterTest(TestCase): def setUp(self) -> None: super().setUp() self.fake = Faker() self.user = User.objects.create_user(username="testuser", password="12345") self.client.force_login(self.user) def tearDown(self): self.client.logout() # ... def test_unset_successfully(self): """Werify unsetting "filter_category_id" session field.

No errors or messages of any kind show up in terminal or in developer in Chrome. There is no JS on this page just straight html: I used the same approach on the a different project but for this it doesn't work. What could be the issue with my code. models.py class Department(models.Model): depart_code = models.CharField(max_length=20,unique=True) depart_name = models.CharField(max_length=100, blank=True, null=True) def __str__(self): return self.depart_name views.py class DepartmentAddView(CreateView): model = Department form_class = DeptAddForm template_name = 'hrms/department_form.html' def form_valid(self, form): form.save() return redirect('/') forms.py class DeptAddForm(forms.ModelForm): depart_name = forms.CharField( max_length=100, widget=forms.TextInput( attrs={ 'class': 'span8', } ), label = "*Department Name", ) departt_code = forms.CharField( max_length=100, widget=forms.TextInput( attrs={ 'class': 'span8', } ), label = "*Department Code", ) class Meta: model = Department fields = ['depart_code', 'depart_name'] hrms/department_form.html <form class="form-horizontal row-fluid" method="POST">{% csrf_token %} <div class="control-group"> <label class="control-label" for="basicinput">Department Code</label> <div class="controls"> {{ form.depart_code }} </div> </div> <div class="control-group"> <label class="control-label" for="basicinput">Department Name</label> <div class="controls"> {{ form.depart_name }} </div> </div> <div class="control-group"> <div class="controls"> <button type="submit" class="btn-success">Submit Form</button> </div> </div> </form> -
How to get Django models data in python script variables?
I want to get the data stored in django models dynamically into my python script. But so far I have not found any solution. I'm new to django so would appreciate the help. -
Make a ForiegnKey to an unknown model in django
I'll illustrate by example I have class Stone(models.Model): # name, color, whatever class Member(models.Model): # whatever class Image(models.Model): stone = models.ForiegnKey(Stone, on_delete=...) # this should have the model that needs images image = models.ImageField() I'm using a foriegnKey to the Image model to make multiple images, But This forces me to create an Image model for each Model, In my example, Stone can has multiple images right? I want Member and all my models that need images to use the same class, I want to make only one images table. I've been searching for a while but I don't think I know what should be the search text, I read about ContentType but I don't think I understand what it does and I don't even know if it's the what I'm asking for.
