Using the URLconf defined in questionbook.urls, Django tried these URL patterns, in this order
I am trying to upload file from django admin interface and make it downloadable for user so that user can download it onclick But every time i click on download button it says something like this I am using pdf file here. Using the URLconf defined in questionbook.urls, Django tried these URL patterns, in this order: admin/ posts/ [name='list'] ^static/(?P<path>.*)$ ^media/(?P<path>.*)$ The current path, posts/Ths is a post/Aditya-Kumar_1.pdf, didn't match any of these.

Edit fields before create using ModelSerializer
I have a pallet that have contents inside. I need to assign a specific number to the pallet, based to a foreign key value (But that is not in the code yet). With postman, when I POST with some json body; If I give some number field, then get an error that number cannot be duplicated. If I don't send number(because I'm giving it on customized create method), I get an error that number is a required field. If I remove number from PalletSerializer, it saves, but when I need to get it, there is no number to see. Which is the correct way to achieve adding data before create? Here are the serializers: class ContentSerializer(serializers.ModelSerializer): class Meta: model = models.Content fields = ('id', 'quantity', 'kilograms', 'container') class PalletSerializer(serializers.ModelSerializer): contents = ContentSerializer(many=True) class Meta: model = models.Pallet fields = ('id', 'number', 'receipt_waybill', 'client', 'contents',) def create(self, validated_data): contents_data = validated_data.pop('contents') number = 123456 pallet = models.Pallet.objects.create(number=number, **validated_data) for content_data in contents_data: specifications_data = content_data.pop('specifications') instance = models.Content.objects.create(pallet=pallet, **content_data) instance.specifications.set(specifications_data) return pallet -

use sessions out of the views django
I made a Custom template tag using this doc like this in my Django application : myproject/ __init__.py models.py templatetags/ __init__.py myCustomTags.py views.py in the myCustomTags.py, I need to use some variables that there are in views.py so I save those variables in session , and tried to get them in myCustomTags.py, but noting worked and it does not recognized my sessions. I used this doc ,but it seems that this method wants me to use session_keys. in this method my question is that how to use the sessions without the key or somehow pass the keys from views.py to myCustomTags.py too . here is my code in this method: views.py: from importlib import import_module from django.conf import settings SessionStore = import_module(settings.SESSION_ENGINE).SessionStore from django.contrib.sessions.backends.db import SessionStore my_session = SessionStore() def user_login(request): if request.method == "POST": username = request.POST.get('username') password = request.POST.get('password') # some process to validate and etc... my_session['test_session'] = 'this_is_my_test' my_session.create() return redirect(reverse('basic_app:index')) myCustomTags.py from django import template from importlib import import_module from django.conf import settings SessionStore = import_module(settings.SESSION_ENGINE).SessionStore from django.contrib.sessions.backends.db import SessionStore my_session = SessionStore() register = template.Library() @register.simple_tag def userStatusMode(): status = my_session['test_session'] return status base.html: {% load dynamic_vars %} {% userStatusMode as user_status_thing %} <!-- and … -
Django : pre selection or tags. model relations
Django Version is 2.1.7 Hello, i have a OneToMany Relation and i ask my self if there is a possibility to make some kind of pre-selection (Tags or so?) for my Farmers? Because not every Farmer has or wants Chickens or he is specialist in Cows only. Means, right now, whenever i want to assign an individual Animal to a Farmer, i see all Farmers displayed in my Django Admin. With a growing Number of Farmers it gets confusing. So i thought to insert some Kind of Model Field in my Farmers Model... like chickens = true or not true and cows = true or not true or to introduce a new model for every species. My Goal is, to assign a set of species to a every farmer. So that the Next time i want to add a chicken django shows only Farmers that will work with Chickens on their Farmland, it makes no sense to Display all Farmers, when some Farmers know that they handel only a specific set of species. As a Newbie i would guess i have to make some new models for every Species with a ManyToMany Relation? So Farmers >< Species X, Y, Z … -
Override related manager in inherited model
Strange problem when working with Django models and related fields/managers, hopefully someone has run into this problem before. I have the following model structure defined: class CustomManager(models.Manager): use_for_related_fields = True def __init__(self, *args, **kwargs): self._param = kwargs.pop("param", True) super().__init__(*args, **kwargs) class MyModel(models.Model): id = models.AutoField(primary_key=True) class BaseRelatedModel(models.Model): id = models.AutoField(primary_key=True) objects = CustomManager() class SubRelatedModel(BaseRelatedModel): related = models.ForeignKey(MyModel, related_name="related_objs", on_delete=models.CASCADE) objects = CustomManager(param=False) As you can see, I have a BaseRelatedModel which sets its manager to be an instance of CustomManager, which sets the default _param value to True. I then subclass this model in SubRelatedModel and attempt to override the objects manager with a new instance of a CustomManager, this time setting its param value to False. The manager override does not seem to work when I attempt to access all related SubRelatedModel objects from a given MyModel instance. In [1]: m = MyModel.objects.create() In [2]: m.related_objs._param Out[2]: True I would expect the m.related_objs._param to return False, since that is the parameter of the objects manager on the SubRelatedModel. Any ideas why this isn't taking effect, or another approach I could use for this problem? Thanks! -

django left join + group by count(*), includes zero counts
class ItemGroup(models.Model): name = models.CharField(max_length=50) class Item(models.Model): name = models.CharField(max_length=50) group = models.ForeignKey(ItemGroup, on_delete=models.CASCADE) I want to display all the item groups, and for each group show the number of items the group has, and include groups which has no items.

Duplicate Content Type in Django after copying Postgres Directory
Situation I have a django app (using postgres as the database) running in production. I am trying to measure/improve performance, and I'd like to do that by copying data from the production instance (which has by far the best data, in terms of quantity and quality) onto my local machine, and run the server locally. I copy the Postgres folder out of which the DB is running on the production machine to my local machine (using scp), and start up the DB from that now local folder, and my local django server. Functionally, I can interact with the app completely normally, without issue. However, as soon as I make a change to my models, generate a migration, and try to migrate (again, to this local version) I get errors: django.db.utils.IntegrityError: duplicate key value violates unique constraint "django_content_type_app_label_model_<HASH>_uniq" DETAIL: Key (app_label, model)=(<APP_NAME>, <CONTENT_TYPE>) already exists. <APP_NAME> and <CONTENT_TYPE> are the specific names of the app and content type for my app. The content_type is a type that has existed in the database for a long while and not affected in my model change/migration.

django model foreign key AttributeError
In my Django project, I have two apps : "music" and "user". I am trying to create a table in my app "music" as a joint table between the table "MusicPiece" and the table "Member" from the other app "user".

How to interpolate dates and values, from database, through Django Models?
I'm new in Django and I have a database with 4 tables containing values from sensors and the datetime that the measures were taken. The problem is: the sensors have a deadband and the measures are wrote just when this deadband value are overcame, so the 4 tables don't have the measures synchronized by datetime. One of my applications needs the synchronization of these measures and I want organize by date and interpolate the datas putting the previous value when the deadband are not excited, instead of a JOIN setting NULL. For example: Sensor 1: Datetime | Value1 28/02/2018 00:00:00 0 28/02/2018 00:00:30 10 28/02/2018 10:00:00 10.3 28/02/2018 10:10:00 10.6 28/02/2018 10:11:00 12 Sensor 2: Datetime | Value2 28/02/2018 00:00:00 0 28/02/2018 00:00:40 13 28/02/2018 10:00:00 9.3 28/02/2018 10:11:01 32 28/02/2018 10:11:37 11.6 Expected result: Datetime | Value1 | Value2 28/02/2018 00:00:00 0 0 28/02/2018 00:00:30 10 0 28/02/2018 00:00:40 10 13 28/02/2018 10:00:00 10.3 9.3 28/02/2018 10:10:00 10.6 9.3 28/02/2018 10:11:00 12 9.3 28/02/2018 10:11:01 12 11.6 28/02/2018 10:11:37 12 32 The databases used will be SQLite (development) and PostgreSQL (deployment).

Middlware triggering error twice in django
