AttributeError: 'ManyRelatedManager' object has no attribute 'log_order'
I have the following model classes with many to many relations and I am trying to loop through the query to find if there is a match in one of the fields log_order but I keep getting AttributeError: 'ManyRelatedManager' object has no attribute 'log_order': To get a better idea here is the model: class Log(models.Model): ................................... log_order = models.IntegerField(validators=[MinValueValidator(1)],blank=True, null=True) date = models.DateTimeField(...........) class LogForm(forms.Form): ............................. log_order = forms.IntegerField() class ActiveSession(models.Model): log = models.ManyToManyField(Log) .................................. In my views I am trying to get the data in the form and saving in the log model which is currently working fine. My next step is to loop through the ActiveSession.log to check if the log_order is available to just update it instead of adding a new log to the session. Here is the views: def addlog(request, id): url = request.META.get('HTTP_REFERER') # get last url active_session = ActiveSession.objects.get(id=ActiveSession.objects.last().id) if request.method == 'POST': # check post form = LogForm(request.POST) if form.is_valid(): data = Log() data.log_order = request.POST.get('log_order') data.save() # save data to table active_session.log.add(data) print('Log added to Session') # for i in active_session.log.log_order: # print(i) # # for i in active_session.log.log_order.all(): # if data.log_order == i: # print("Available in Active Session") # else: # … -

Create one-to-one model record, or update if it already exists, in this Django view
UserComputedInfo model has a one-to-one relationship with CustomUser model. I want to update or create a record in UserComputedInfo during a form update to CustomUser. I managed to create/update a record in views.py Here is the code; from .models import UserComputedInfo def profile(request, username): if request.method == "POST": user = request.user form = UserUpdateForm(request.POST, request.FILES, instance=user) if form.is_valid(): user_form = form.save() # How to save post_code to copy_input in UserComputedInfo model user_computed_info_instance = UserComputedInfo(user_id=user.id) user_computed_info_instance.latitude = 1.18 # or whatever value to be assigned user_computed_info_instance.save() messages.success(request, f'{user_form.username}, Your profile has been updated!') return redirect("profile", user_form.username) return redirect("homepage") This is a follow-up question to a flawed answer I posted to my own past question. Save values into another database table with one-to-one relationship in Django during form update The answer works the first time when a new record is being created. However, it fails to work the second time profile() is run because there is already an existing record. How do I modify profile() such that a new record will be created if there is no existing record and an update will be made if the record already exists?

Add cart on django-shopping-cart ( error 'str' object has no attribute 'id')
I use django-shopping-cart 0.1 to add carts, but here the data comes from an api, so I did not create a product model When trying to add I have this error: ('str' object has no attribute 'id' ) this error comes from the cart.py module of django-shopping at: id = product.id I remind you that at the level of the API which retrieves the products, I have the fields (code, designation) so I pass the 'code' field as a parameter to add a basket, as there is no 'id' View.py @login_required def cart_add(request,code): url='http://myapi/Article/GetArticle' x=requests.get(url) content=x.json() articles=content['articles'] for article in articles : if article.get('code') == code : cart=Cart(request) myarticle=article.get('code') cart.add(product=myarticle) return render(request,'cart/deatil.html') Module Cart.py class Cart(object): def __init__(self, request): self.request = request self.session = request.session cart = self.session.get(settings.CART_SESSION_ID) if not cart: # save an empty cart in the session cart = self.session[settings.CART_SESSION_ID] = {} self.cart = cart def add(self, product, quantity=1, action=None): """ Add a product to the cart or update its quantity.

Filtering Foreign Key Based on Another SlugRelatedField in POST Requests in Django Rest Framework
I'm using Django Rest Framework and have a model with multiple ForeignKey relationships and am POSTing their slugs rather than id. The issue is that the second ForeignKey requires a queryset that is filtered based on the first. Here is a not-so-perfect example: # models.py class Student(models.Model): slug = models.SlugField(...) class Class_(models.Model): slug = models.SlugField(...) class ReportCard(models.Model) student = models.ForeignKey(Student) class_ = models.ForeignKey(Class_) grade = models.CharField(...) # serializers.py class ReportCardSerializer(serializers.ModelSerializer): student = serializers.SlugRelatedField(queryset=models.Student.objects.all(), slug_field='slug') class_ = serializers.SlugRelatedField(queryset=models.Class_.objects.filter(???), slug_field='slug') # need to filter based on student here class Meta: model = models.ReportCard fields = '__all__' # use all fields How do I do this? student in the serializer does not return the model and I don't know how to access the data inside of ReportCardSerializer to grab the string from the POST request to manually filter class_. -
Better way to insert and list on the same page with django
I'm creating a todo list using django, and I found it more interesting to be able to list and insert on the same page than creating a page just to insert The way I managed to do it so far was as follows: class IndexView(CreateView, ListView): models = Todo template_name = 'index.html' queryset = Todo.objects.all() context_object_name = 'todos' fields = ['nome'] success_url = reverse_lazy('index') I wonder, is there a better way to do this? -
Django doesn't creates objects for all rows in postgresql
I'm scripting a migration tool to get my data from an old software to a new version with different data structures. While looping through the csv-files I'm creating the objects. The problem is that every object gets created in postgres but django doesn't. I'm getting errors like: duplicate key value violates unique constraint "api_order_pkey" DETAIL: Key (id)=(159865) already exists. Order.objects.get(pk=159865) does return "Does not exist" But a SELECT * FROM api_order WHERE pk = 159865 directly in Postgres finds a row. with open("order.csv","r") as f: reader = csv.reader(f) for row in reader: Order.objects.create(pk = row[0], ordernr= row[1],....)` thats of course a short version of it. On the import of about 250.000 rows this problem appears with about 100 rows. I had the same problem with deleting. I ran Order.objects.all().delete() but in Postgres there where still a few rows left while Order.objects.all() returned an empty Queryset. Is there something I can do about this? Has anyone had a similar problem? -
How do I get the JWT tokens from user in Django RestFramework
I have a DRF project using Simple-JWT for authentication. When a user logs in, they get a response containing the access and refresh tokens in the serializer.data. However: When testing on the Apis I can manually copy and paste these tokens and add them to headers when making requests. However in production, Where are these tokens stored on the user's side? How will the user be able to add the access token to requests that are protected? (they can't copy-paste like me) How will they use the refresh token to renew the access token I would appreciate if someone cleared this up for me. -

How to get value of <option> in django view?

Django button click gets triggered but not updating model
I tried to upload the image several times, for some reason it just won't upload. I will explain in detail - This table is on my django template.It will display data from a model called "WorkOut". This page has a form above this table for manual data input. Three fields in the table are going to be dynamic, that is where the issue is. In the picture you will see the "Start Time" field that says none. I want to fill this field with a button click. Idea is to click the button, that will trigger a views.py function and that will update the model and then display on this page. Once I do this successfully I will add the end time and do some calculations after. I added a small form in the for loop to generate the button- <td> <form method="get"> <input type="submit" class="btn" value="Start Time" name="start_time"> </form> </td> Here is the views function that it is suppose to trigger- def index_2(request): if(request.GET.get('start_time')): time=datetime.now().strftime('%H:%M:%S') WorkOut.objects.update(start=time) products=WorkOut.objects.all() context={'products': products} return render(request, 'myapp/index.html', context) This page is the index and no separate url for the button click. I don't think I need one. Here is the main index views: def … -

Django HttResponse has no attr status_code, but docs have :)
I'm using default django httpresponse, like this: return HttpResponse("Validation Error", status_code=400) And i got exception like "HttpResponse has no attribute status_code". But in the docs we have info about this attr (docs link) If we look at source code, we can see: class HttpResponse(HttpResponseBase): ... def __init__(self, content=b'', *args, **kwargs): super().__init__(*args, **kwargs) # Content is a bytestring. See the `content` property methods. self.content = content ... Not explict usage of status_code, let's look parent's init: class HttpResponseBase: def __init__(self, content_type=None, status=None, reason=None, charset=None, headers=None): ... if status is not None: try: self.status_code = int(status) except (ValueError, TypeError): raise TypeError('HTTP status code must be an integer.') if not 100 <= self.status_code <= 599: raise ValueError('HTTP status code must be an integer from 100 to 599.') self._reason_phrase = reason And here in params we can see status. If we back to my example, correct version of this looks: return HttpResponse("Validation Error", status=400) And my question is: "Is there place in docs where was talk about status of HttpResponse and if not, how i can make issue or bring this info to django-developers?" The way I see it, it's not obvious enough. -
