Do we have to host our Django site for our Flutter App backend?
Suppose I am creating a todo list app in Flutter. I have used Django to connect flutter's backend with the local host database. Now my API's(Django Rest Framework) are working fine if the is on local machine. But what if I deploy my Flutter app to Play Store? Then I need to host my Django site as well or it can be upon the local machine? -
How to make CRUD on a model through related model in Django Rest Framework?
For example: models class User(models.Model): nickname = models.CharField(max_length=30) email = models.CharField(max_length=60) class Group(models.Model): name = models.CharField(max_length=60) user = models.ForeignKey(User, on_delete=models.CASCADE) I have simplest serializers and view sets and I need to make CRUD part which on url would look like this: GET POST api/groups/{group_id}/users/ PUT PATCH DELETE api/groups/{group_id}/users/{user_id} so I can just see users which are related to the pointed group. Is there any provided or common way for such case? Thanks :) -
Django is not serving staticfiles
I would like to use django staticfiles, but unfortunately I can't get it to serve to images locally. This is what I have done so far: settings.py: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'content.apps.ContentConfig', ] STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_DIRS = (os.path.join(BASE_DIR, "static"),) When I do a print(os.path.join(BASE_DIR, 'staticfiles')) I see the correct local path. urls.py: from django.contrib import admin from django.conf import settings from django.conf.urls.static import static from django.urls import path import content.views urlpatterns = [ path('admin/', admin.site.urls), path('', content.views.index, name='index'), path('/about', content.views.about, name='about'), ] urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) templates: {% load static %} ... {% static "css/master.css" %} resolves to /static/css/master.css I am maybe missing something, just need an additional pair of eyes. Thanks. -
jsonb join not working properly in sqlalchemy

How to retrieve data from comma separated values in Django admin
I am using a legacy database where many to many values are stored in an array like 1,2,3,4.. In django forms I am trying to use the below custom field to read multiple values. However they are getting stored as ['1','2'] instead of 1,2. Since it is an already existing database, I cannot go with many to many field. I have to store and retrieve values in the said format. class MultiSelectFormField(forms.MultipleChoiceField): widget = forms.CheckboxSelectMultiple def __init__(self, *args, **kwargs): self.max_choices = kwargs.pop('max_choices', 0) super(MultiSelectFormField, self).__init__(*args, **kwargs) def clean(self, value): if not value and self.required: raise forms.ValidationError(self.error_messages['required']) # if value and self.max_choices and len(value) > self.max_choices: # raise forms.ValidationError('You must select a maximum of %s choice%s.' # % (apnumber(self.max_choices), pluralize(self.max_choices))) return value I have changed my modelfield from ManytoManyField to Charfield in the process of achieving this functionality. In django admin page, if the dbtable has 1 value in the multiselectfield, django admin edit form page is showing the selected value, but if there are multiple values, nothing is getting populated... How do I achieve manytomany kind of functionality in this way--- like the column in the db field should have array of id's of the selected values. -
Bulk save edited items with Django?
I am editing a large number of model instances in django and I would like to save all these changes at once. The instances are already created so I am not looking for bulk_create. The changes are also different for each instance, so I can't use QuerySet.update(...) to apply the same change to all of them. I would like to replace this: for item in items_to_modify: item.some_field = process_new_data() item.save() by something like: for item in items_to_modify: item.some_field = process_new_data() items_to_modify.save_all_at_once() I am using django 3.1 -
How to make a choice field from many to many related classes in django?
I have a django web project. There are products for sales points. The points can have similar and different products to sale.

In this page, i want to create choice fields, and first i want to ask user which point he/she wants, then according to this point, i want to show available products(products that only belong to that sales point) to user.

how to use django class model self in views.py
I want to create a filtering function and output the result value to the table. [A - models.py] class School(models.Model): .... def proceeding(self, request): from_date = request.GET.get('from_date') to_date = request.GET.get('to_date') student= Student.objects.filter(school_id=self.id) return Feedback.objects.filter( entry_date__range=[from_date, to_date], student_id__in=student).values('entry_date').distinct().count() [B- models.py] class Student(models.Model): ... school = models.ForeignKey(School, on_delete=models.CASCADE) class Confirm(models.Model): .... school = models.ForeignKey(Student, on_delete=models.CASCADE) I know why the results are not displayed. I know that the request written next to self in models.py doesn't work. However, the reason you must use it in models.py rather than views.py is that you must use self. Please answer to the seniors who know how to make a request in models.py!! -

Assign a model to another model using ModelChoiceField
I am new to Django and would like to create a platform where teachers can create student profiles and assign reports to the specific student. Therefore, I have made two models (Student & Report) and two CreateViews. When creating a report, the teacher has the option to select a student from a choice field. This I have done using ModelChoiceField. However, when submitting the report model, the students name is not saved to that model. How can I accomplish this? Ultimately I would like to have a profile to each student showing their info and reports attached to their model. models.py class Student(models.Model): author = models.ForeignKey(User, null=True, on_delete=models.CASCADE) name = models.CharField(max_length=30, default="") age = models.CharField(max_length=2, default="", blank=True) class Report(models.Model): date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, null=True, on_delete=models.CASCADE) title = models.CharField(max_length=30) forms.py class StudentForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(StudentForm, self).__init__(*args, **kwargs) class Meta: model = Student fields = ['name','age',] class ReportForm(forms.ModelForm): student = forms.ModelChoiceField(queryset=Student.name, initial=0) class Meta: model = Report fields = ['title','file','player',] views.py class StudentCreate(LoginRequiredMixin, CreateView): model = Student template_name = 'student_create.html' form_class = forms.StudentForm def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) class ReportCreate(LoginRequiredMixin, CreateView): model = Report template_name = 'report_create.html' form_class = forms.ReportForm def form_valid(self, form): form.instance.author = … -

Iframe stops working after upgrading to Django 3.2 LTS
I was using Django 2.2 up till now and I recently tried upgrading to Django 3.2 We use a website live chat plugin called tawk.to which works by embedding an iframe to our page with the chat option in there. However, after upgrading to Django 3.2, even though the plugin's JS code is loading, the iframe is missing from the website altogether. I am not sure what is causing the issue. Is the iframe blocked in Django 3.2 or do I have to enable any setting for it? -
Django - reading MultiPolygons from postgres database does not return valid geometries
I'am creating web app to display some data in forms of charts, maps etc. I am using Bokeh for plotting. For maps I need to load shapefile with MultiPolygons containing regional borders. I have it loaded in my PostgreSQL database and I can display geometries from pgAdmin. I have a model for this table registered, here's the code class Polska(models.Model): gid = mdls.AutoField(primary_key=True) region = mdls.CharField(max_length=80, blank=True, null=True) geom = mdls.MultiPolygonField(srid=0, blank=True, null=True) When I'm trying to load these shapes and pack them into GeoDataFrame from geopandas I get a massive wall of text with an error (its just a snippet, basically it prints me the entire geometry) Input must be valid geometry objects: MULTIPOLYGON (((494179.5260320738 358814.2954531405, 494173.5314778397 358816.6456283908, 494178.0633204972 358822.8603784787, 494231.7738932786 358896.5675205989, 494321.7782545781 359023.6103092115, 494341.6988730072 359051.7332468079.....))) Code from loading in my views:geodf = gpd.GeoDataFrame(pd.DataFrame(Polska.objects.values("region","geom")),geometry="geom") So there is a geometry object, but for some reason it doesnt read as one. Interestingly when I try to check the type of this Multipolygon object it tells me "MULTIPOLYGON EMPTY". Can someone help me out and suggest where the problem can be? If some info is missing than let me know, I'll update asap. -

Is my approach for creating a custom user model for my Ecommerce website correct?
I am creating a Custom User Model for my Ecommerce website . There are three types types of users in my website : Buyer Seller Company employee (Note : Company employee are further classified into the following types) 3.a) Sales support 3.b) Moderation team 3.c) Analytics team 3.d) Ticket manager 3.e) Super admin So basically there are 7 different types of users in our ecommerce seller , buyer and 5 types of company users . Now , In order to achieve this , I first created a new app called "Users" in my freshly made blank Django project . Inside the Users/models.py , I created the Custom user model as follows : #Users/models.py from django.contrib.auth.models import AbstractUser from django.db import models user_type_choices = ( (1, 'buyer'), (2, 'seller'), (3, 'Sales-Support'), (4, 'Moderator-Team'), (5, 'Analytics-Team'), (6, 'Ticket-Manager'), (7, 'Super-Admin') ) class CustomUser(AbstractUser): age = models.PositiveIntegerField(null=True, blank=True) user_type = models.PositiveIntegerField(choices=user_type_choices) phone = models.PositiveBigIntegerField() After this model was created , I did the required changes to the settings.py file in the main app of the project by adding the "Users" app to the list of installed apps and adding the following line : AUTH_USER_MODEL = 'Users.CustomUser' Is my approach for creating custom user … -

How can I access my graphql endpoint with authentication implemented using graphene_django_crud?

For a few weeks I've been busy working on a research of different forum-like websites. A few examples are; Quora, Stack Overflow and of course Reddit. You would help me out a lot if you could fill in this survey (takes 5 min most!) in which I would like your opinion and usage of this platform; Stack Overflow. Your submission will be highly appreciated. PS: I'm sorry for the misusage of this platform, but this is the best way to reach the actual users. https://docs.google.com/forms/d/e/1FAIpQLSeI9ipMOUEmruvpGTFIId9Xgx1f-J-R8lKGoECMDWjPIfENcA/viewform?usp=sf_link -
