Link two models
I have two models: Profile and Course. Profile stores user info. Course has a title, description and date. User can sign up for the course using link. My goal is to make a list of users, who belong to each course. I tried using ForeignKey, but i need to have user added to the list only after he signs up for it. class Course(models.Model): course_title = models.CharField(max_length=200) course_description = models.TextField() course_published = models.DateTimeField("date published", default = datetime.now()) course_users = [] def __str__(self): return self.course_title def course_signup(request): # here i guess i need to somehow add the user to the list Course.course_users.append(Profile.id) return redirect("main:homepage") Profile code: class Profile (models.Model): user=models.OneToOneField(User, on_delete=models.CASCADE) image=models.ImageField(default='default.jpg',upload_to='profile_pics') def __str__(self): return f'{self.user.username} Profile' def save(self, *args, **kwargs): super(Profile,self).save(*args,**kwargs) img = Image.open(self.image.path) if img.height > 300 or img.width >300: output_size = (300,300) img.thumbnail(output_size) img.save(self.image.path) I expect to have a list of users in Course. -
Why is my auto-generated migration producing an error when I run it?
I'm using Python 3.7, Django, and PostGres 9.5. I recently edited my model to remove some columns and add another ... class MainSiteStatByHour(models.Model): total_score = models.DecimalField(default=0, max_digits=12, decimal_places=2) num_articles = models.IntegerField(default=0) hour_of_day = IntegerField( null=True, validators=[ MaxValueValidator(23), MinValueValidator(0) ] ) index = models.FloatField(default=0) ... class Meta: unique_together = ("hour_of_day",) I generated my migration and all seemed to go well ...

Django - Simple query after using Serializer
I serialized my tables as outlined here: serializing tables. The output of this serialization was a JSON object that contain the queryset I wanted that used all of my tables. It renders perfectly on the template. Now, I need to pass the values from only one table as JSON to the template to create a select option menu using AJAX, but when I try to pass the id and category fields for that one table the Response passes the entire queryset I got when I serialized the tables. The queryset does not include all the options in the category table, only the ones that have been use in at least one entry. So, I need a new query that contains only the values in the category table. I tried this: Serializing Django objects data = serializers.serialize('json', Model.objects.all(), fields=('name','category')) return HttpResponse(data, safe=False) And it gave me the whole query set from earlier. I tried: data = serializers.serialize('json', Model.objects.all()) return HttpResponse(data, safe=False) And I got the full queryset again. I tried: data = Model.objects.all() return JsonResponse(data, safe=False) And: data = list(Model.objects.values()) return JsonResponse(data, safe=False) I get the full queryset. How can I query only the values in one table after serializing? Thanks! -
Django third party library url pattern before custom url pattern? (url pattern order)
Using Django (REST Framework) this is my root url conf : ... (imports) urlpatterns = [ re_path(r"^confirm-email/(?P<key>[-:\w]+)/$", accounts_views.email_verification, name="account_confirm_email"), path('admin/', admin.site.urls), path('request/', include('request.urls')), path('rest-auth/', include('rest_auth.urls')), path('rest-auth/registration/', include('rest_auth.registration.urls')), re_path(r'^account-confirm-email/', TemplateView.as_view(), name='account_email_verification_sent'), ] now, I am using the django-rest-auth library for authentication. This library sends a email to the user after they submit the registration form, for the purpose of activating the user's email address. In this email is a link, which is obtained by reversing an url pattern, the url pattern named: account_confirm_email the django-rest-auth library comes with it's own url pattern named account_confirm_email, in the following file, to be precise: python3.7/site-packages/rest_auth/registration/urls.py: ... (imports) urlpatterns = [ ... url(r'^account-confirm-email/(?P<key>[-:\w]+)/$', TemplateView.as_view(), name='account_confirm_email'), ] I expect my own url pattern to be the one that is reversed, not the rest-auth one, since mine comes first in order. As the Django docs state: Django runs through each URL pattern, in order, and stops at the first one that matches the requested URL. https://docs.djangoproject.com/en/2.2/topics/http/urls/ But in practice the rest-auth pattern is the one that is being reversed, why does this happen? To be complete, I see that the Django docs also say: Django determines the root URLconf module to use. Ordinarily, this is the value … -
How to get latest and earliest from a django QuerySet
In my django app, there are a few different ways that I get a QuerySet object of the same model. I would like to use one function to render the data -- and this has been working fine, until I decided to add both earliest and latest time to display on top of the list. Here's my latest attempt: def render_list(request, objList): latest = earliest = None if objList: latest = objList.latest('time').time earliest = objList.earliest('time').time context = {'objList': objList, 'earliest': earliest, 'latest': latest, } return render(request, 'list.html', context) This produces the error message: TypeError: Cannot reverse a query once a slice has been taken. Is there a way to get around this problem? -

<QuerySet ... > ... must be a ... instance | How to get data from forms using the formset?
There is a ProductCreateForm form. Need to add the SpeciallyPriceForm form to it. As I understand it, this is solved with the help of formset. There is a CBV view with a formset (maybe wrong). If I understand correctly, it is necessary to form the main form with formset in the get method, and then process them in the post method... def get_context_data(self, *args, **kwargs): ctx=super(ProductsCreate, self).get_context_data(*args, **kwargs) ctx['special_form'] = SpeciallyPriceForm() return ctx def get(self, request, *args, **kwargs): self.object = None if kwargs.get('slug'): category = Category.objects.filter(slug=kwargs.get('slug')).first() self.initial.update({'category': category}) return self.render_to_response(self.get_context_data()) def post(self, request, *args, **kwargs): self.object = None form = self.get_form() special_form = SpeciallyPriceForm(self.request.POST) print(special_form) if form.is_valid() and special_form.is_valid(): return self.form_valid(form) else: return self.form_invalid(form) All the fields are rendered, but there is a problem with the fact that when I try to view the data from the ProductCreateForm form, I get an error Cannot assign ", ]>": "Product.category" must be a "Category" instance. The problem is that in the form I refer to entries from the category table, but I refer not directly, but through the providers table as follows. def __init__(self, *args, **kwargs): user = self.request.user provider = Provider.objects.filter(user=user.id).last() self.fields['category'] = ModelMultipleChoiceField(queryset=provider.category.all()) Provider has MTM connection with Category.

Django + Celery with long-term scheduled tasks
I'm developing a Django app which relies heavily on Celery task scheduling, using Redis as backend. Tasks can be set to run at a large periods of time, as well as in a few seconds/minutes. I've read about Redis visibility timeout and consequences of scheduling tasks with timedelta greater than visibility timeout (I'm also in the process of dealing with it in a previous project), so I'm interested if there's anything neater than my solution, which is to have another "helper" task run 5 minutes before the "main" one needs to be executed, scheduling the "main" task to run in required time, storing task id in DB, and then checking in "main" task if the stored task id is the one that is being run. The last part (with task id storing) is required as multiple runs of "helper" task could spawn a lot of "main" task instances, but with this approach each will have different task id. I really hate how that approach sounds and how it works, as if the task is scheduled to be run a month from current time, "helper" and "main" tasks are executed up to a hundred times. I also know that it's an … -

How to use DRF serializers with Grapahene
I am following this tutorial for using Graphene with Django, and everything was going smooth, until I reached the Integration with Django Rest Framework section. This section says that you can reuse DRF serializers with Graphene, by creating serializers clones, but it doesn't say what to do with such clones in order to reuse DRF serializers with Graphene. This are my serializers and clones: from rest_framework import serializers from graphene_django.rest_framework.mutation import SerializerMutation from GeneralApp.models import Airport from ReservationsManagerApp.serializers import ReservationSerializer from ReservationsManagerApp.models import ReservationComponent, ReservationHotel, ReservationRoundtrip, ReservationTransfer, ReservationTour, ReservationService, Hotel class ReservationMutation(SerializerMutation): class Meta: serializer_class = ReservationSerializer class ReservationComponentGraphSerializer(serializers.ModelSerializer): component = serializers.SerializerMethodField() class Meta: model = ReservationComponent fields = ('id', 'reservation', 'dertour_bk', 'day', 'content_type', 'object_id', 'comment', 'is_invoiced', 'component') def get_component(self, instance): components_models = { 'reservationhotel': ReservationHotel, 'reservationroundtrip': ReservationRoundtrip, 'reservationtransfer': ReservationTransfer, 'reservationtour': ReservationTour, 'reservationservice': ReservationService, } component = components_models[instance.content_type.model].objects.get(id=instance.object_id) return self.get_component_string(instance.content_type.model, component) def get_component_string(self, component_model, component): components_get_string = { 'reservationhotel': self.get_hotel_string, 'reservationroundtrip': self.get_roundtrip_string, 'reservationtransfer': self.get_transfer_string, 'reservationtour': self.get_tour_string, 'reservationservice': self.get_service_string, } return components_get_string[component_model](component): def get_hotel_string(self, component): return component.hotel.name def get_roundtrip_string(self, component): return component.roundtrip.name def get_transfer_string(self, component): origin_str = self.get_place_str('origin', component) destination_str = self.get_place_str('destination', component) return "{} => {}".format(origin_str, destination_str) def get_place_str(self, case, component): places_models = { 'airport': Airport, 'hotel': Hotel, } if … -
Python Django Invalid Input Syntax Error for Int even though it isn't supposed to be an integer
I am making an e-commerce app using Python, Django 2.1, and PostgreSQL. When I click on one of the categories to show products specific to that category, it tells me that I have a data error.

Delete certain django app from a django project on heroku and exclude it from future push
In my django project named website I have two apps app1 & app2 . I want to keep app2 accessible only through my local machine. I dont want app2 to be publicly accessible online through my website. I have already pushed my entire website to heroku. So how can I delete app2 from heroku website and avoid pushing app2 to heroku in future. I have tried following things: Added app2/ to .gitignore. So future changes are avoided. But current version of app2 still exist on heroku website. I deleted app2 on local machine and tried to push the changes, but I got error in static collection saying no app named app2 exists. I would also like to avoid having Django's default admin functionality available through my website. I would like to keep it local too. Thanks -

Django YouTube API Upload fails with iPhone
I can upload videos to YouTube through my Django application, but only when they are uploaded from my laptop. YouTube gives me a "Processing abandoned" error when I upload the same video through my iPhone. I am running Ubuntu 16.04.3 with Django version 1.11.20 and Python 2.7. I am using a function in my views to receive the uploaded file, and, if it is over 2.5 megabytes, grab the file from the /tmp directory, and if it is under 2.5 megabytes, process the file from memory. This works when I upload video files from my laptop, but it fails when I upload video files from my iPhone. To be clear, I don't get errors from Django/Python. The file seems to upload, process, and delete just fine. But after YouTube receives it, I go into my YouTube Studio, and it gives me a "Processing abandoned. This video could not be processed," error. def upload_to_youtube(request): if request.method == 'POST' and request.FILES['video']: video_file = request.FILES['video'] if video_file.size >= 2621440: fname = request.FILES['video'].file.name storage = DjangoORMStorage(CredentialsModel, 'id', request.user.id, 'credential') credentials = storage.get() client = build('youtube', 'v3', credentials=credentials) body = {...} with tempfile.NamedTemporaryFile('wb', suffix='yt-django') as tmpfile: with open(fname, 'rb') as fileobj: tmpfile.write(fileobj.read()) insert_request = client.videos().insert( … -
Authentication issues with django-webpack-loader with vuejs and django restframework and restauth
I created a frontend with vue.js using vue cli and webpack and the backend using django restframework where I am also implementing social authentication for google using restauth. Before I used the django webpack, the login and logout would work fine and as expected. (I should mention that I was using tokenauthentication) in my settings.py, file I had both the sessionauthentication as well as tokenauthentication enabled in the restframework authentication possibilities. The two settings being enabled never caused any trouble. However, after using the django webpack loader to render the frontend vue files using django templates, I would continuously get an error that said my csrf token was not present. The login would work fine in this case if I removed the sessionauthentication option out of the settings.py file however. Does anyone know why this is happening? https://medium.com/@rodrigosmaniotto/integrating-django-and-vuejs-with-vue-cli-3-and-webpack-loader-145c3b98501a I used the above blog to implement the webpack loader functionality I removed the 'rest_framework.authentication.SessionAuthentication', line from my settings.py after using the django-webpack-loader and the issue was resolved REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authtoken', 'rest_framework.authentication.BasicAuthentication', 'rest_framework.authentication.SessionAuthentication', ) } I basically changed it like below: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authtoken' 'rest_framework.authentication.BasicAuthentication', ) } -

How to get a value from a static page and post it into a model
I have showed the values {{ p.emri }} and {{ p.cmimi }} which are in the "Produkte" model onto my Browse.html. So far so good , but now I'm trying to write a function in views.py to get this values and post them into another model named "AddToCart" when i press the submit button.
