django download file not found
I'm using Python 3.6 and django 2.2 to develop a webserver. I want to have a webpage displaying a download link for a file I generated based on user input. In my setting.py I have: MEDIA_ROOT = os.path.join.(BASE_DIR,'media') MEDIA_URL='/media/' In my views.py I have query.outputfile.name = os.path.join('submission',query_id,'output_file.txt') to associate the filefield object to the file that I created: path/to/project/media/submission/[query_id]/output_file.txt And when I include print(query.outputfile.url) I got: media/submission/[query_id]/output_file.txt In my html template I have <a href={{ query.outputfile.url }} download> Download output file here </a> On the webpage the file link points to [local ip]/media/submission/[query_id]/output_file.txt But when I click on the link chrome says "Failed - No file" and on the cmd line I got Not Found: /media/submission/[query_id]/output_file.txt I found related questions like this one but do not understand what's wrong with my code. My questions are: The .url seems to be relative to my MEDIA_ROOT, but why it cannot find my file? Does the cmd line error point to the absolute path /media/... ? I tried to make that path and file but still got the same error. What should I do to generate the download link? Thanks -
Is there a way of a inserting blank datetimefield from another table?
class Customer(models.Model): last_purchase = models.DateTimeField(blank=True, null=True) I have a blank DateTimeField, which will continuously update itself with the last modified DateTimeField in the corresponding table. class Order(models.Model): customer = models.ForeignKey(Customer, null=True, on_delete= models.SET_NULL) date_created = models.DateTimeField(auto_now_add=True, null=True) How will this look on views? -

Django... Why template page doesn't show results of the query in the view function
Sorry I am new to django and I made mistake or bunch of mistakes somewhere and I don't see what is wrong... Django also doesn't let me know where is the mistake... If somebody pinpoint me to the answer or let me know what is wrong that would be totally awesome... Thank you I have 2 models: one is the Director (pk = director_name) and one is the Worker (pk = worker_name)... Means family names, unique... They are many to many connection for the database. One worker can be under 2 supervisors... So, another model is Connection (fk = director_connect, fk = worker_connect, pk = (director_connect, worker_connect))... By the way, in postgresql the database model as I just described, but when I run "inspectdb" in cmd... it gives me: worker_connect = models.OneToOneField(...)// I made this connection by the alphabet, but somehow for Django, instead of ForeignKey it is OneToOneField? Can I just change it to models.ForeignKey(...)? And then apply changes? director_connect = models.ForeignKey(...) // as expected... def __str__(self): return f'{self.worker_connect}' def get_absolute_url(self): return reverse('director-detail', args=[str(self.director_connect)]) class Meta: managed=False db_table 'Connection' unique_together = (('director_connect', 'worker_connect')) ...So, the idea is to be able to find which worker under whose supervision, and whom … -

How to get intermediary models instances related to a specific model in a Django symmetrical m2m relation?
Since Django 3.0, setting symmetrical=True for recursive m2m relationships using a through model is supported. [docs] For exemple, with the following models, where Town objects are symmetricaly linked together through Roads objects : class Town(models.Model): neighboors = models.ManyToManyField('self', through='Road', symetrical=True) class Road(models.Model): from_town = models.ForeignKey('Town', models.CASCADE, related_name='road_from') to_town = models.ForeignKey('Town', models.CASCADE, related_name='road_to') How to get all Road instances related to a specific town? As the doc explains, related_name of the two fk in the Road models have to be different, meaning a single reverse acessor like town.related_road will not work. Of course, I can set two different related_name and join the results of two queries, but that does not seems very Pythonic to me: class Town(models.Model): ... @property def roads(self): return self.road_to + self.road_from Is there any other way I can achieve this ? -
Why does Django create a new instance instead of update?
I want to modify some of my 'Location' object with an UpdateView. class LocationUpdateView(UpdateView): #form_class = LocationForm model = LocationTemplate fields = ['address','district','grid_x','grid_y'] #template_name = 'locationTemplate_update_form' def get_success_url(self): return reverse('location_detail', kwargs={'pk': self.object.pk}) def post(self, request, *args, **kwargs): form = self.get_form() if form.is_valid(): self.object = self.get_object() for loc in Location.objects.all(): if self.object.location_name == loc.location_name: setattr(loc,'address',(form.cleaned_data['address'])) setattr(loc,'district',(form.cleaned_data['district'])) setattr(loc,'grid_x',(form.cleaned_data['grid_x'])) setattr(loc,'grid_y',(form.cleaned_data['grid_y'])) loc.save() return self.form_valid(form) else: return self.form_invalid(form) However, instead of updating the objects, the above loop creates a new object with the update information(except the location_name is None). I was expecting setattr() to modify the attributes of that specific loc instead of creating new instances. models.py class LocationTemplate(models.Model): location_name = models.CharField(max_length=50, null=True, blank=True) address = models.CharField(max_length=300, null=True, blank=True) district = models.CharField(max_length=300, null=True, blank=True) grid_x = models.IntegerField(null=True, blank=True) grid_y = models.IntegerField(null=True, blank=True) def __str__(self): return self.location_name + ", Address: " + self.address + ", District: " + self.district + ", Coordinates: (" + str(self.grid_x) + ", " + str(self.grid_y) + ")" forms.py class LocationForm(forms.ModelForm): class Meta: model = LocationTemplate #exclude = ('patient',) fields=['location_name', 'address','district', 'grid_x','grid_y'] -

Accessing model attributes in Django
I'm trying to show users the product variations that they have selected. While the code is working and saving the variation in the database, I am not being able to show them on my html page.

pytest-django: users created with create_user are always authenticated
I'm trying to write a fixture to generate Django users from custom user model. The weird thing is that the newly created user results authenticated by default, while I expect it to be anonymous. What am I doing wrong? Fixture: import pytest @pytest.fixture def create_user(db, django_user_model): def make_user(**kwargs): return django_user_model.objects.create_user(**kwargs) return make_user Test the fixture: @pytest.mark.django_db def test_fixture_create_user(create_user): user = create_user(user={'email': 'foo@bar.com', 'password': 'bar'}) assert user.is_authenticated is True # <-- this should be False but it's True assert user.is_anonymous is True # <-- this fails The test fails this way: E assert False is True E + where False = <CustomUser: foo@bar.com>.is_anonymous -

Div exceeding max width and fixed position
I'm working with a product page and currently trying to make it responsive. I have a button wrapper that shows when visiting the website with a mobile device. This wrapper is like the one in Hermes website (also switch to mobile), where the 'buy' button has a fixed position. This is the css: @media screen and (max-width:640px){ *{ max-width: 100%; } (...) .button-wrapper{ transform: translateY(0); display: flex; -webkit-box-orient: vertical; -webkit-box-direction: normal; align-items: baseline; justify-items: center; padding: 2rem; z-index: 99; bottom: 0; left: 0; right: 0; justify-content: center; align-content: center; position: fixed; width: 100%; max-width: 100%; background-color: #f4f5fc; } Somehow, the container is bigger than the width of the device, which leaves a really akward space. Here's what I mean: Another problem is that the inicial position of the wrapper is below the height of the screen. The foto from above isn't cropped, and as you can see, the button is half-way there. But when I scroll down, this happens: Now the whole wrapper can be seen. Any help is appreciated! Thanks in advance. EDIT: This is the HTML: <body> {% include 'loader.html' %} <header> <div class="d-flex justify-content-center"> <div class="row"> <div class="responsive-logo"></div> <div class="pullcontainer"> <a href="#" id="pull"><i class="fa fa-bars fa-2x"></i></a> </div> … -
Django Problem: Unable to import 'django.db'
I am following this Django Polls App Documentation to learn Django and I ran into this error saying Unable to import 'django.db' in my virtual environment. This entry on stack overflow led me to this visual studio documentation on virtual environments which did not work for me. UsingPython: Select Interpreterto select an environment did not solve my problem since Python 3.8.2 64-bit *'env': venv was NOT available for me as seen from this image. Only the Python 2.7.17 64-bit ('polling-website': venv) option was available. The status bar image shows that I am running on Python 3.8.2 64-bit version. Knowing that this is a virtual environment issue, I'm wondering if I installed the virtual environment correctly. I installed my virtual environment using the command python3 -m venv. My virtual environment appears to be working fine as seen from the terminal below. The environment was activated properly and the python manage.py runserver command ran properly and I was able to successfully open the server.

Cannot assign "8": "Comment.post" must be a "Post" instance
I can access a post using its ID or a slugified version of its title. Both localhost:8000/post/working-in-malaysia and localhost:8000/post/8 load the post called Working in Malaysia. I want users to be able to comment on any post. The comments load with the code comments = Comment.objects.filter(post=post.id ,active=True) When I manually select the value for the Post field, the comments are saved to the sites database. But I want the value for the Post field to be automatically populated. Based on the current post being displayed. I have tried new_comment.post = post.id and new_comment.post = post.title. views.py if request.method == 'POST': comment_form = CommentForm(data=request.POST) if comment_form.is_valid(): new_comment = comment_form.save(commit=False) new_comment.post = post.id new_comment.save() else: comment_form = CommentForm() urls.py urlpatterns = [ path('', PostListView.as_view(), name='blog-home'), path('post/new/', PostCreateView.as_view(), name='post-create'), path('post/<slug:pk_slug>/', views.post_detail, name='post-detail'), #path('post/<slug:the_slug>/', views.post_detail, name='post-detail'), path('post/<int:pk>/update/', PostUpdateView.as_view(), name='post-update'), path('post/<int:pk>/delete/', PostDeleteView.as_view(), name='post-delete'), path('about/', views.about, name='blog-about'), #path('your-name/', views.about2, name='blog-about'), path('facebook/',TemplateView.as_view(template_name='blog/index.html'), name="facebook") ] -

Django_Filters and queryset
Hi guys I'm building a simple django website where the user can look for long play. The problem right now is that I can't figure out why the filter, built with the django_filters library, doesn't work. If you type "Queen" in the search bar in the home you are redirected to the searches.html where are listed all the LPs by Queen (just 4). On the left there's a filter. If you type "kind" in the form and submit then you should just see the album "Kind of Magic". This doesn't work. And I think the problem is the queryset "sp": class searchesView(TemplateView): template_name = "search/searches.html" def post(self, request, *args, **kwargs): print('FORM POSTED WITH {}'.format(request.POST['srh'])) srch = request.POST.get('srh') if srch: sp = Info.objects.filter(Q(band__icontains=srch)) | Info.objects.filter(Q(disco__icontains=srch)) myFilter = InfoFilter(request.GET, queryset=sp) sp = myFilter.qs paginator = Paginator(sp, 10) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) return render(self.request, 'search/searches.html', {'sp':sp, 'myFilter':myFilter, 'page_obj': page_obj }) else: return render(self.request, 'search/searches.html') I think the problem is the queryset because then I tried to build a result.html page where I listed all the LPs in the database and applied the same filter above and here it works perfectly: def result(request): result = Info.objects.all() myFilter = InfoFilter(request.GET, queryset=result) result = …
