Invalid embedded document instance provided to an EmbeddedDocumentField
I am currently working on an billing app and require to have orders inside a bill for that I have following two models Bill and orders class Bill(Document): billNo = IntField(unique=True, blank=False) table = ReferenceField('Table',reverse_delete_rule=1) orders = EmbeddedDocumentListField('Order', required = False) total = models.FloatField() discount = models.FloatField(blank=True) grandtotal = models.FloatField() payment_option = ReferenceField('PaymentOption',reverse_delete_rule=1) paid = models.BooleanField(default=False) class Order(EmbeddedDocument): food = ReferenceField(Food) quantity = IntField(required = True) complementory = BooleanField(default = False) and their serializers are as class OrderSerializer(EmbeddedDocumentSerializer): class Meta: model = Order fields = 'all' read_only_fields = ('id',) class BillSerializer(DocumentSerializer): orders = OrderSerializer(many = True) class Meta: model = Bill fields = '__all__' read_only_fields = ('id',) def create(self, validated_data): orders = validated_data.pop('orders') bill = Bill.objects.create(**validated_data) bill.orders = [] for order in orders: print(order) bill.orders.append(order) bill.save() return bill But whenever I pass a json like { "billNo": "4", "table":"5a93eb7f59951a3320a0b4d8", "payment_option":"5a93eddf59951a2fd4dbabe9", "orders":[{ "food":"5a93c2c759951a018c5e18b5", "quantity":"2", "complementory":"False" }] } the bill object is created but the order is not added and it gives the error mongoengine.errors.ValidationError: ValidationError (Bill:5a94f76859951a19d4688aeb) (Invalid embedded document instance provided to an EmbeddedDocumentField: ['orders']) I am using django rest framework and since it is mongodb i am using django rest framework mongo engine.

Unicode issue with pygithub and django
I'm trying to connect to this org githubtraining This is my code on views.py: def home(request): global org email=request.GET['email'] password=request.GET['password'] g = Github("user", "paswword") org = g.get_organization('githubtraining') list_rep= org.get_repos() context = { 'list_rep': list_rep, 'org':org } return render(request, 'Github/repo.html',context) But everytime I try to render the view I got this error: UnicodeEncodeError at /auth/ 'ascii' codec can't encode character '\u200b' in position 24: ordinal not in range(128) Is this because of something wrong in my call? Or maybe there's something else there? -

Django: Querying M2M table after object creation returns empty array
I'm using a Django signal to run a block of code after a model saves using post_save. The signal receiver in post_save gets an instance of the object sends it to a method for some processing before the instance is sent to a third party via network. One of my models, foo, has a many-to-many relation with another model, bar, and I need to add an array named bar_id that contains ids of each bar before I send foo to the third party. This configuration works when updating a foo instance however when I create a new instance of foo and I query for its relations (see the troublesome query in the Add Bar's ID to Foo and send it to third party section, the query is returning an empty query set even though the relation exists in the database. This exact same query returns a query set if I update the same model moments later. Any ideas of why this may be happening? Here's the code: Register the signal from django.apps import AppConfig class FooConfig(AppConfig): name = 'foo' def ready(self): import foo.signals Signal Code from django.dispatch import receiver from django.db.models.signals import post_save from django.conf import settings from django.db.models import … -

context and dictionaries python Django
So I have the following code: views.py: def topics(request): """Show all topics""" topics = Topic.objects.order_by('date_added') context = {'topics': topics} return render(request, 'learning_logs/topics.html', context) return render(request, 'learning_logs/topic.html', context) I understand that I am querying the database and sorting the data by date then storing that data in the topics variable. My first question is, is the topics variable storing the data as a list? (assuming multiple entries). If so when I have the following code in my html file topics.html: <ul> {% for topic in topics %} <li>{{ topic }}</li> {% empty %} <li>No topics have been added yet.</li> {% endfor %} </ul> why do I need pass the data stored in topics into a context dictionary for topics.html to loop through and display the data? why not loop through the topics variable itself? I'm just confused on the use of "contexts" Thanks for the help in advance. -
Django Model.objects.all() returns unexpected empty QuerySet
I have some problem while trying to use a MySQL database with Django. The database contains a table named items. This database is imported from a development system to a production system. This database is the second database in addition to an existing SQLite databased used by other teams. There had been an error message about no such table, but I was able to solve it with this question. It assume that there are no migration errors. The MySQL database works fine in the development system (tested using python manage.py shell), but it doesn't work in the production system (tested the same way.) I tested the import with: $ python manage.py shell >> from project.models import Item >> Item.objects.all() <QuerySet []> I created the models.py file with: $ python manage.py inspectdb > models.py I verified that the database and the table items actually contains records. (Although some fields are stored as unicode text, if that makes any difference to the situation.) I am using Django 2.0.2 with Python 3.6.3. -

How to show a update form while keeping the original data in Django?
I'm using Django Forms to do some updating work.For example,I write a FilmForm to present a film information form: class FilmForm(forms.Form): name = forms.CharField() director = forms.CharField() release_year = forms.DateField() ......(many other infos) And I create and save a model instance using the form.Next time I want to modify only one info,like 'director',and update the model info using the FilmForm. def FilmUpdate(request,pk): if request.method == 'POST': ... else: form = FilmForm() return render(request,'film_update.html', {'form':form}) but when the form show up,the html inputs are all blank,and have to input all the original data again while the only item I want modify is just 'director'.So how to present the update form with the original data keeping? -
Django - Trying to delete 3rd party app, but getting "doesn't declare an explicit app_labels"
I am trying to uninstall a 3rd party app called Silk. I have removed all traces from Silk from my project, include settings.py, urls.py and anywhere else in the project. Now when I try to start the server, I get the following error - RuntimeError: Model class silk.models.Request doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.. I tried doing python manage.py migrate silk zero, but it says that silk is not a valid app (it's not in my project folder). Then I said screw it, and ran python manage.py reset_db to completely reset my database, but even after that, I still get the same error. How do I get rid of Silk? -
proper way to set up many to many relation where intermediary field has foreign keys django
I have a custom user field and a permissions field in a django app. The documentation says the following: https://docs.djangoproject.com/en/2.0/ref/models/fields/#django.db.models.ManyToManyField that we are to use the manytomany through method. But I am confused on its proper implementation. Below I have my two models. I am asking for assistance in understanding how the through field applies in this case or at all. class STUser(AbstractBaseUser): email = models.EmailField(unique=True) name = models.CharField(max_length=255) companyname = models.CharField(max_length=200, blank=True, null=True) userphoto = models.CharField(max_length=200, blank=True, null=True) signupvaildatestring = models.CharField(max_length=200, blank=True, null=True) is_active = models.BooleanField(default=False) phone = models.CharField(max_length=10, null=True, blank=True) jobtitle = models.CharField(max_length=100, null=True, blank=True) # password field function is provided by AbstractBaseUser and the permissions table class Permissions(models.Model): venue = models.ForeignKey(Venue, on_delete=models.SET_NULL, blank=True, null=True) user = models.ForeignKey(STUser, on_delete=models.DO_NOTHING) isclient = models.BooleanField(default=False) isvenueviewer = models.BooleanField(default=False) isvenueeventplanner = models.BooleanField(default=False) isvenueadministrator = models.BooleanField(default=False) issuitsviewer = models.BooleanField(default=False) issuitsadministrator = models.BooleanField(default=False) issuitssuperuser = models.BooleanField(default=False) now I am supposed to use the through fields on this? The Example the docs uses its below does it differ in a way from my implementation where I do not need to use the through field? from django.db import models class Person(models.Model): name = models.CharField(max_length=50) class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField( Person, through='Membership', through_fields=('group', 'person'), … -
psycopg2.OperationalError: FATAL: password authentication failed for user "<my UNIX user>"
I am a fairly new to web developement. First I deployed a static website on my vps (Ubuntu 16.04) without problem and then I tried to add a blog app to it. It works well locally with PostgreSQL but I can't make it work on my server. It seems like it tries to connect to Postgres with my Unix user. Why would my server try to do that?

django sqlite3 URIs not supported
Odd situation. Django 2.x in its features for sqlite3 drive turns on uri support. It seems to only be a problem seen in python 3. On machines with older version of sqlite, in my case 3.6.20, the problem of URIs not supported does not arise with exactly the same virtualenv and codebase. On machine with sqtlite3 --version showing 3.7.17 it does arise. The funny thing is the feature is only supported in sqlite3 after 3.7.7 or so from what I read. So apparently django sees it is supported but it really isn't at the level of the internal sqlite3 drivers in python? (guessing) In [3]: sqlite3.version_info Out[3]: (2, 6, 0) In [4]: sqlite3.sqlite_version_info Out[4]: (3, 7, 17) On the machine it does not work on and as expected last line is (3, 6, 20) on machine it does work on. Now I don't have full control of the machine. I thought just to pull over the lower version but no luck there. Internal libraries determine actual version even when you run sqlite3 on the command line. I can hack the relevant part of the django driver setup but that is less than pleasing even though I do have control of … -

DoesNotExist --Matching Query Error
I'm trying to list a group of deals by category I have a Deal model and a Category Model, where the Category is a Foreign Key of a Deal like so: class Deal(models.Model): title = models.CharField(max_length=200) slug = models.SlugField(max_length=140, unique=True) description = models.TextField(default='') category = models.ForeignKey(Category) The urlpattern for a category page looks like this: url(r'^category/(?P<category>\w+)/$', deals_by_category, name='category') The view for this urlpattern is this: def deals_by_category(request,category): category_deals = Deal.objects.filter(category__name=category, ) return render(request, 'deals/category.html', {'category_deals': category_deals}) and then my category.html template is looping through these returned deals like this: {% for deal in category_deals %} <h5 class="card-retailer">{{ deal.retailer}}</h5> <p class="card-title">{{ deal.title }}</p> Now the issue arises if i click on predetermined category link like this: http://localhost:8000/deals/category/Apparel/ but the error is pointing NOT to my 'deals_by_category' view, but to the individual view for each deal---the stack trace is pointing to that second line below.

Django sort and regroup multiple fields
I am trying to regroup a field and sort on another in Django. My use case is different, but let's use the Django regroup template as an example. Using this dataset. cities = [ {'name': 'Mumbai', 'population': '19,000,000', 'country': 'India'}, {'name': 'Calcutta', 'population': '15,000,000', 'country': 'India'}, {'name': 'New York', 'population': '20,000,000', 'country': 'USA'}, {'name': 'Chicago', 'population': '7,000,000', 'country': 'USA'}, {'name': 'Tokyo', 'population': '33,000,000', 'country': 'Japan'}, ] Using the regroup tag, this is the output: India Mumbai: 19,000,000 Calcutta: 15,000,000 USA New York: 20,000,000 Chicago: 7,000,000 Japan Tokyo: 33,000,000 How can I sort this information by population and yet still keep the grouping? This is the expected output that I would like to see: Japan Tokyo: 33,000,000 USA New York: 20,000,000 Chicago: 7,000,000 India Mumbai: 19,000,000 Calcutta: 15,000,000 How would one query the database to keep the groupings that are needed for reorder in the Django template to work properly and yet still maintain the sort order of population? How would this work on a date object instead of an int? -

Django Channels Live Chat: AttributeError: 'Message' object has no attribute 'as_dict'

This is my code in consumers.py @channel_session def ws_receive(message): label = message.channel_session['room'] room = Room.objects.get(label=label) data = json.loads(message['text']) m = room.messages.create(handle=data['handle'], message=data['message']) Group('chat-'+label).send({'text': json.dumps([m.as_dict()])}) I have tried some things that …
