How to post in bulk in Django-Rest-Framework with a different format
My Model : from django.db import models Create your models here. from rest_framework.exceptions import ValidationError class Results(models.Model): test_taker = models.ForeignKey('users.User', null=True, related_name='testtakerId', on_delete=models.CASCADE) question_detail = models.ForeignKey('questions_detail.Questions_detail', null=True, related_name='answersId', on_delete=models.CASCADE) test_id = models.IntegerField(null=True) answer = models.CharField(max_length=255, null=True) custom_answer = models.CharField(max_length=255, null=True) What i Want to post: { "test_taker": 1, "test_id": 1, "question": [ { "question_id": 1, "answer": 2, "custom_answer": "c1" }, { "question_id": 2, "answer": 3, "custom_answer": "c2" }, { "question_id": 3, "answer": 4, "custom_answer": "c3" }, { "question_id": 2, "answer": 1, "custom_answer": "c4" } ] } Cuurently what i am doing is: In my views.py : (I am using rest_framework_bulk) class AddResult(ListBulkCreateUpdateDestroyAPIView): lookup_field = 'pk' serializer_class = ResultsSerializer def get_queryset(self): return Results.objects.all() def perform_create(self, serializer): test_taker = self.request.data['test_taker'] test_id = self.request.data['test_id'] serializer.save(test_taker=test_taker, test_id=test_id) My Serializer: class ResultsSerializer(BulkSerializerMixin,serializers.ModelSerializer): class Meta: model = Results fields = '__all__' list_serializer_class = BulkListSerializer What is happening is it just stores 1 result and that has test_taker = 1 and test_id = 1 which it takes from the outer part of the JSON. What i want is for it to store all the records in the format of [test_taker , test_id, question_id , answer, custom_answer] Thanks in advance for positive responses. -
python-social-auth redirect to the user profile in Django
I am using the wonderful python-social-authpackage, and more precisely the social-auth-app-django version since my project is using the Django Framework. Once the user is registered/logged in via any social backend, I'd like to redirect the user to their own very user profile. I know I can set a static URL in my settings.pysuch as: SOCIAL_AUTH_LOGIN_REDIRECT_URL = '/logged-in/' But how can I dynamically redirect the user to their profile given that I know their username/slug? If I could set variables in the settings.py it'd be something like: SOCIAL_AUTH_LOGIN_REDIRECT_URL = '/accounts/<slug:slug>/' But of course I can't do that. Is there any way I can achieve what I want? -
NameError: name 'LoginView' is not defined
I'm installing the Openstack Stein Horizon service (dashboard) following the tutorial on the site. I encounter an error due to the Django version and fix it using this explanation Switch from django string_concat to format_lazy. The next issue that appears was AttributeError: module 'django.contrib.auth.views' has no attribute 'login', which I googled and came again as a Django version incompatibility.

Celery worker permission denied
To be quite honest I do not really know what I am doing ;) Recently I installed Mayan EDMS in a chroot on my NAS. So far I got it working ... at least I can login and so forth. But I cannot upload any files and I guess this has to do with celery (which I did not knew about before). Because I am in a chroot I cannot use supervisord for these celery workers and I started them from the command line. e.g. nice -n 19 /path/to/my/mayan-edms/bin/celery worker -A mayan -Ofair -l ERROR -Q statistics,tools,common_periodic,parsing,document_states,mailing,ocr -n mayan-worker-slow.@%h --concurrency=1 But this throws an error: -------------- mayan-worker-slow.@DiskStation213 v4.3.0 (rhubarb) ---- **** ----- --- * *** * -- Linux-3.2.40-armv7l-with-glibc2.17 2020-04-07 15:15:07 -- * - **** --- - ** ---------- [config] - ** ---------- .> app: mayan:0x41cc8d00 - ** ---------- .> transport: redis://:**@127.0.0.1:6379/0 - ** ---------- .> results: redis://:**@127.0.0.1:6379/1 - *** --- * --- .> concurrency: 1 (prefork) -- ******* ---- .> task events: OFF (enable -E to monitor tasks in this worker) --- ***** ----- -------------- [queues] .> common_periodic exchange=common_periodic(direct) key=common_periodic .> document_states exchange=document_states(direct) key=document_states .> mailing exchange=mailing(direct) key=mailing .> ocr exchange=ocr(direct) key=ocr .> parsing exchange=parsing(direct) key=parsing .> statistics exchange=statistics(direct) key=statistics … -

inputting algorithms to edit django model data
I have a Django project where users can input stings and images similar to a blog like twitter or reddit. The data will be stored in models.py. as such: class Post(models.Model): body = models.TextField(max_length=5000, null=False, blank=False) image = models.ImageField(upload_to=upload_location, null=True, blank=True) then in forms class CreatePostForm(forms.ModelForm): class Meta: model = Post fields = ['body', 'image'] and in views: def view(request, slug): context = {} post = get_object_or_404(Post, slug=slug) context['post'] = post return render(request, 'post/post.html', context) I used Conda to write an algorithm that edits the input photos in a unique way (for example a watermark) but I'm not sure where in my Django project to try an incorporate the algorithm. Forms.py? Models.py? after the data manipulation I would want to create a second views.py so that I could have something like this: def view2(request, slug): context = {} post2 = get_object_or_404(Post2, slug=slug) context['post2'] = post2 return render(request, 'post2/post2.html', context) I was thinking I should create a form.py class roughly like the following: class EditPostForm(forms.ModelForm): class Meta: model = Post fields = ['body', 'image'] def edit(self, commit=True): post.body = self.cleaned_data['body'] post.image = self.cleaned_data['image'] #manipulate img data #output new img and then create a view.py class roughly like the following: def new_post_view(request, … -
Return ManyRelatedManager values in template
I'm new to programming so i'm sure there's an obvious simple solution to this. I have two models (in separate apps): class Order(models.Model): parts = models.ManyToManyField(Part, blank=True) class Part(models.Model): mwos = models.ManyToManyField('mtn.Order', blank=True) The problem is when i render Order in DetailView in template i can't get the queryset of associated values. If i just put {{ order.parts }} i get my_app.Part.None. And if i do this class OrderDetailView(LoginRequiredMixin, DetailView): model = Order def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['parts'] = Part.objects.filter(mwos=self.object.id) return context I get {{ parts }} rendered as empty queryset <QuerySet []>. -

Customizing Django's implicit ManyToManyField's "through" table?
I have two models which are joined through a ManyToManyField. I did not specify a through table manually, so Django created one implicitly. Can I now somehow customize that through table, specifically to alter its ___str___ function? Basically, I'm trying to override the "row title" a TabularInline admin class uses, like in these questions: Remove or edit object name in admin.TabularInline How to override the str method when rendering StackedInline field? https://groups.google.com/d/topic/django-users/d0QPIAklSug But I'd like to avoid customizing the template or creating a "relationship table" explicitly, as right now it's managed by Django. -

Which filter is better and faster
I am relatively new to django and python, so i would really like to know which of these two implementation is the better or faster approach. I am currently using the filter, but i thought of it, and cos i really like list comprehension, i wrote the same code using list comprehension. Both codes do exactly the same thing, but I just want to know from developers with more experience which is better and why. Below are both codes. posts = Post.objects.filter(approved=True).order_by('-date_posted') posts = [post for post in Post.objects.all().order_by('-date_posted') if post.approved] -

Specifically how did you install GDAL? What commands did you run in psql? Thanks in advance! -

I am working on a project and I am a beginner in Django. I am trying to get all the product posts from specific user and then show them.

I am new to Python and am trying to make a music style blog where one can post YouTube videos, Soundclound links etc. using the Django admin page. I have tried using the URLfield model but it doesn't seem to work.
