Cannot serialize Django object with JsonResponse instance
This question seems to have been asked multiple times on SO, but none of the answers seem to work. I have this model: class BaseModel(models.Model): created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Meta: abstract = True class Post(BaseModel): user = models.ForeignKey(User, on_delete=models.CASCADE) content_url = models.URLField(null=False) and I try to serialize it into JSON here: def create_post(request): post_content = request.body post_content_url = save_post(post_content) # returns a string post = Post.objects.create(user=request.user, content_url=post_content_url) post.save() return JsonResponse({"post": post}) When I do this I get the following error: TypeError: Object of type Post is not JSON serializable What am I doing wrong? The JsonResponse class is supposed to dump the object to json: class JsonResponse(HttpResponse): def __init__(self, data, encoder=DjangoJSONEncoder, safe=True, json_dumps_params=None, **kwargs): if safe and not isinstance(data, dict): raise TypeError( 'In order to allow non-dict objects to be serialized set the ' 'safe parameter to False.' ) if json_dumps_params is None: json_dumps_params = {} kwargs.setdefault('content_type', 'application/json') data = json.dumps(data, cls=encoder, **json_dumps_params) super().__init__(content=data, **kwargs) Please help.

Get auto-generated field from model in serializer, without returning it
I have a serializer which is used to invite a new user. In the User Model which this serializer used, there is an autogenerated field for an activation key (which gets emailed to the user). What is the best way to cleanly get the activation key in the serializer, without adding it the the User object which will be returned in the response? For obvious reasons, I don't want the activation key being returned to the front end. models.py: class User(AbstractBaseUser): ... activation_key = models.UUIDField(unique=True, default=uuid.uuid4) ... serializers.py: class UserInvitationSerializer(serializers.ModelSerializer): email = serializers.EmailField() class Meta: model = User fields = ('id', 'email', 'first_name', 'last_name') def create(self, validated_data): user = User.objects.create(**validated_data) random_pass = User.objects.make_random_password(length=10) user.set_password(random_pass) user.save() activation_key = ? send_mail('Email Address Verification Request', 'confirm/email/(?P<activation_key>.*)/$', 'info@mydomain',[user.email]) return user -
Django: Cart matching query does not exist
I've a form that creates a Cart with the text "Random" in a character field, if there is not a Cart object created. This is only to get this recently object's id if it is not already created. cart = Cart.objects.get(id=cart_id) I get an error saying that this query generates an error, however I can see the value of cart_id as a cookie so the Query should execute without problem. But it doesn't according to the error message. As you can see in my view, I'm using this: cart_id = self.request.COOKIES.get('cart_id') if not cart_id: cart = Cart.objects.create(cart_id="Random") cart_id = cart.id cart = Cart.objects.get(id=cart_id) To get the cookie cart_id if it does not exist I created a Cart object with the Random text, only to get it's ID.

Unable to connect to Postgres service using docker and tox
I have a docker application that builds a Postgres database. I am using tox to run my Django tests. When I am running docker-compose run web tox over my docker image in my local machine (I used docker-compose up --build --force-recreate -d to build my docker image) it is showing error as E django.db.utils.OperationalError: could not connect to server: Connection refused E Is the server running on host "127.0.0.1" and accepting E TCP/IP connections on port 5432? But when I am running the only tox command (not on my docker image) it is working fine. I tried to run my Django test without tox that is by using docker-compose run web python manage.py test over my docker image. In this case, it is not showing any errors. I guess I have some problem to run tox over my docker image. Can someone please help me with it? -
How to use Django Filter on a separate page and send the GET data to the original query set page
So let's imagine I have this filterset: class PlayerPageFilter(FilterSet): position = filters.MultipleChoiceFilter(choices=FIELD_POSITION_CHOICES, widget=Select2MultipleWidget) class Meta: model = PlayerDetailPage fields = [] And this view: def get_context(self, request): context = super(PlayerPage, self).get_context(request) context['filter_page'] = PlayerPageFilter(request.GET, queryset=PlayerDetailPage.objects.all()) Then in the PlayerPage template you have something like this: {% for s in filter_page.qs %} {{ s.position }} {% endfor %} How to write a view for the homepage where I can use the same PlayerPageFilter and which sends me to the original template page query set after submitting the form. So not rendering the query set on the homepage but on the original page. -

My default database in my django app is on read-only
On my web app, created with Django, the database 'default' that I am using is on read-only, so I encounter some issue with the admin pages and with the migrate method. The database with the writing access is called with a name because it is not very used compared to the default one. So my question is what is the best solution between changing the name of my databases or modifying the files of the admin and migrate methods? Thank you for your help, -

Django Upgrade from 1.11 to 2.2.1 Problem with URLs and Paths
Today I decided to upgrade my project from Django 1.11 to 2.2.1. I've been working through various issues with my project, and I'm fighting through them. However, I spent most of tonight trying to get the URLs to work and they won't cooperate. Long story short, I have multiple app in my project and each app has a URL with it's own namespace. In Django 1.11 this is working fine. However, when I try to port the logic over to Django 2.2.1, I keep getting an error saying that I have a circular import somewhere probably. Here is a snippit of what works just fine in Django 1.11....... My Main Project...In Django 1.11 url(r'^Main/',include('AppA.urls',namespace="AppA")), But when I try to do this in Django 2.2.1..... I realize that URLs were replaced by paths... path('', include('AppA.urls')), But when I try to start my application it says.... your project does not appear to have any patterns in it. If you see valid p atterns in the file then the issue is probably caused by a circular import. I can't seem to figure out how to create the namespace that is working in django 1.11 so that I can properly reference my urls in … -
Django: Filter variable
In my models.py I filter for two cases. I check if there is: a ticket_on_sale ticket_on_sale_soon If 2) is given but 1) not, then the method should give back True.

How to "translate" this SQL query to queryset in django
So I've got these Django models (the code is simplified by the way): class Travel(models.Model): #there are many other fields origin_city = CharField() end_city = CharField() class Segment(models.Model): start_time = DateTimeField() origin = CharField() end = CharField() travel = ForeignKey(Travel) price = IntegerField() So a travel has a set of segments, for example if the travel is A->B->C->D->E, then the segments are (A,B) , (B,C) , (C,D) and (D,E). I want to get, given an origin and end, the travels that pass through the given origin and then through the given end. For example, if origin and end are (B,D), the example travel is valid, since it goes through B at some point and then it goes through D later, but it wouldn't be valid for (D,B). I know that in SQL, this could be done like this (assuming travel stores ids and segment has them with foreign key restrictions): SELECT t.* FROM travel as t, segment as s1,segment as s2 WHERE t.id = s1.travel_id AND t.id = s2.travel_id AND s1.origin = (user given origin) AND s2.end = (user given end) AND s1.start_time < s2.start_time -
