Problem with filter in django orm by json field
Could someone help me with django orm filter I am trying to filter data by some key in json filed (Postgres, jsonb field) Field in postgres table contains something like { "pet": "dog", "name": "my_lovely_dog" } I build filter like: cond = {"field_name__pet": some_variable} qs = qs.filter(**cond) But when I watch result sql query I see something like: Select * from "table_name" where ("table"."my_field" -> pet) = '"dog"' How I can do it correctly? Why django use "" inside ''? And why django not put key from json in ""? Thank you -
How to call pytest-django from python manage.py test?
I have made my custom management command called pytest_wrp So when I call python manage.py test This bit of code is called: super(Command, self).handle(*args, **options) # this calls the python manage.py test self.stdout.write("My code starts from here.") management.call_command(pytest_wrp.Command(), '--pact-files="{argument}"'.format(argument=path_to_file), '--pact-provider-name="MyService"', verbosity=0) The pytest_wrp basically has this code in it: class Command(BaseCommand): help = "Runs tests with Pytest" def add_arguments(self, parser): parser.add_argument("args", nargs=argparse.REMAINDER) def handle(self, *args, **options): pytest.main(list(args)) # This gets executed but this calls default pytest not django-pytest But this calls pytest not pytest-django Hence the extra arguments that I am passing don't get recognized and pytest can't start the test suite. I wanna pass the extra arguments for some of the test cases. If there is some way to call pytest-django directly and pass the extra arguments in code that would be optimal. -
fetch a list of related many-to-many values as a field on the related model queryset in django
I have models that look like this: class Schedule(models.Model): field1 = models.CharField(max_length=20) plans = models.ManyToManyField(Plan, through="Schedule_Plan") users = models.ManyToManyField(User, through="Schedule_User") class Plan(models.Model): field2 = models.CharField(max_length=20) users = models.ManyToManyField(User, through="Plan_User") class Plan_User(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) plan = models.ForeignKey(Plan, on_delete=models.CASCADE) is_owner = models.BooleanField(default=True) class Schedule_Plan(models.Model): plan = models.ForeignKey(Plan, on_delete=models.CASCADE) schedule = models.ForeignKey(Schedule, on_delete=models.CASCADE) class Schedule_User(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) schedule = models.ForeignKey(Schedule, on_delete=models.CASCADE) is_owner = models.BooleanField(default=True) I would like to create a queryset that contains the following field outputs: schedule.id, schedule.field1, schedule.users.is_owner, [list of schedule.plans.id] I am able to get the first three fields together using: qs1 = Schedule.objects.filter(users__in=[self.request.user]).order_by('-id') qs2 = Schedule_User.objects.filter(user_id=self.request.user.id).order_by('-schedule_id').values('is_owner') data = zip(qs1, qs2) ...and I unpack them in tags using: {% for schedule, ownership in plans.schedule_data %} ---- do something using schedule.field1 ----- ---- do something using ownership.is_owner ----- {% endfor %} All of that is successful. I need to add the list of plans to the output so I can access the list similarly. I have read about prefetch_related() but have not been able to implement it successfully for this issue. Also I've considered using values_list but haven't been successful there either. I am open to any ideas that will produce the desired result. *Please note, plans … -

Django : How to extract full address previously saved as default in template
I have made a checkout process where users can add a new address and set it as default for next orders The address contains Street_address, Street address2, Province, Country, Postal_Code and Phone. I wanted to show the full default address before proceeding. I have reached to the point where I show the Street_address only but I tried to show the rest but failed. How to extract the rest of the address? This is the view: class CheckoutView(View): def get(self, *args, **kwargs): try: order = Order.objects.get(user=self.request.user, ordered=False) form = CheckoutForm() context = { 'form': form, 'couponform': CouponForm(), 'order': order, } shipping_address_qs = Address.objects.filter( user=self.request.user, address_type='S', default='True' ) if shipping_address_qs.exists(): context.update( {'default_shipping_address': shipping_address_qs[0]}) def post(self, *args, **kwargs): form = CheckoutForm(self.request.POST or None) try: order = Order.objects.get(user=self.request.user, ordered=False) if form.is_valid(): use_default_shipping = form.cleaned_data.get( 'use_default_shipping') if use_default_shipping: print("Using the defualt shipping address") address_qs = Address.objects.filter( user=self.request.user, address_type='S', default=True ) if address_qs.exists(): shipping_address = address_qs[0] order.shipping_address = shipping_address order.save() else: messages.info( self.request, "No default shipping address available") return redirect('core:checkout') else: print("User is entering a new shipping address") shipping_address1 = form.cleaned_data.get( 'shipping_address') shipping_address2 = form.cleaned_data.get( 'shipping_address2') shipping_province = form.cleaned_data.get( 'shipping_province') shipping_country = form.cleaned_data.get( 'shipping_country') shipping_postal_code = form.cleaned_data.get( 'shipping_postal_code') shipping_phone_number = form.cleaned_data.get( 'shipping_phone_number') if is_valid_form([shipping_address1, shipping_province, shipping_country, … -
Django custom through table for ManyToMany relationship: save method not being called during model form save (or save_m2m)
Here's the setup... class RequestUserBaseClass(Model): # There is middleware that sets "thread.request" with each request - that is functioning fine thread = threading.local() created_by = ForeignKey(User) ... def save(self, *args, **kwargs): self.created_by = RequestUserBaseClass.thread.request.user ... class Meta: abstract = True class CustomThroughTable(RequestUserBaseClass): ... class SimpleModelClass(RequestUserBaseClass): ... manyfield = ManyToManyField(OtherTable, through=CustomThroughTable) ... class SimpleModelForm(ModelForm): class Meta: fields = [... 'manyfield' ... ] in a view... if simple_form.is_valid(): simple_form.save() Bottom line: I have this base class, it sets the created by field by working together with some custom middleware that puts the user in a thread local variable. Works great, use it all over the place. Then I have a model with a many to many that uses a custom through table. When the form gets saved, I get an integrity error about created_id not being set, and from inspecting the output it is when the entry in the through table is being added into the database. This lines up because I only get the error when the many to many field has been edited. Why would this be though? Would "save()" not be getting called when that through table entry is added or something? Feel free to ask for more info … -
Slice an array in two (balanced) halfs in DJango template

Exclude fields when nesting serializer Django REST Framework
serializers.py class ThreadSerializer(serializers.ModelSerializer): author = UserSerializer(read_only=True) last_post_user = UserSerializer(read_only=True) class Meta: model = Thread fields = '__all__' read_only_fields = ('locked', 'views', 'post_count', 'last_post_time') class ChannelSerializer(serializers.ModelSerializer): threads = ThreadSerializer(many=True, read_only=True) class Meta: model = Channel fields = ['id', 'name', 'description', 'category', 'threads'] class CategorySerializer(serializers.ModelSerializer): channels = ChannelSerializer(many=True, read_only=True) class Meta: model = Category fields = ['id', 'name', 'channels'] You'll notice I have nested ChannelSerializer in CategorySerializer, when I visit the endpoint that queries data using CategorySerializer I was hoping it would list out only data from ChannelSerializer however it lists data from ThreadSerializer as well, I'd assume this is expect behavior since ThreadSerializer is nested inside ChannelSerializer. Is there some elegant way I can exclude fields when I nest serializers? in this case I'd like to exclude threads from appearing when querying data using the CategorySerializer I tried the answer from a similar question but can't seem to get it working in my case unfortunately, it ends up listing the threads again, also I'd think there's a simpler way to do it. -

Integrate Raw SQL Query into Django ORM with Aggregations
I'm trying to integrate this RAW query into a django ORM query but I'm facing problems to apply the raw query and the orm query The original query which works fine with postgres querytools: "SELECT SUM(counter),type, manufacturer FROM sells GROUP BY manufacturer, type" Now I tried to integrate this into a django-orm query like this: res_postgres = Sells.objects.all().values('manufacturer','type','counter').aggregate(cnter=Sum('counter')) But what I get is just a the counter cnter ... What I need is the result from the Raw query which looks like this What I also tried is to use values and field names. Like Sells.objects.values('manufacturer'....).aggregate(cnter=Sum(counter)) But then django is building a query which integrates a GROUP BY id. Which is not what I need. I need an aggregation of the entire data not the object level while keeping the information of the other fields. When I use Cars.objects.raw() it asks me about primary keys, which I also don't need. Any hints here? is that possible with Django ORM at all? -
