Object of type QuerySet is not JSON serializable Django with AngularJS
I have a Django project where am using AngularJs as frontend. I have a very simple search where user will search a code and if the code matches from the db table it will show it.

Django rest framework, DELETE request responds with "Method \"GET\" not allowed." to every valid request
Here is my code for DELETE method for a "comment" model (views.py): class CommentDelete(DestroyAPIView): queryset = Comment.objects.all() serializer_class = CommentSerializer in urlpatterns it looks like this (urls.py): ... path('delete/', views.CommentDelete.as_view()), ... For some reason when I make a direct DELETE request, the result is "Method \"GET\" not allowed." I'm also using swagger, and it gets even more weird there. There is a DELETE option but it doesn't provide any parameter field even after I've specified it in views.py (lookup_field = 'id'). When I run it, it gives me an expected error: Expected view CommentDelete to be called with a URL keyword argument named "id". -
Nested foreign key serializer with customized response in Django not working

But I want the full nested list of Challenge_progressLog_detail with Challenge Detail, And supporting organization detail items. I used below serializer class in in challenge_progresslog_detail ==> serializer.py file for get customized response in list.

Git db.sqlite and wsgi.py file keep reverting on pull
I have a python/django/wagtail project that I built locally using db.sqlite3. I did an initial push with everything to github, and then pulled it to my server. I made a change to the wsgi file and did some work in the cms which updated the database. I made some changes locally. I changed my .gitignore to exclude db.sqlite3 and wsgi.py. git add ., git commit, git push origin master. then, on the server, sudo git pull origin master. db.sqlite3 reverts back to before I made the cms changes and the wsgi.py reverts back to pointing to my dev settings. I made the changes back to the cms but now I need to do another update when I have made even more cms changes and I do not want to overwrite the database again. wsgi.py is a small fix but still.

Crispy form does not work with specific form field and button
I am trying to use crispy-forms but ran into the following two problems. This is the form.py from django import forms from menu.models import Item class TableCheckInForm(forms.Form): guest_count = forms.IntegerField(min_value =0) # item = forms.ModelChoiceField(queryset=Item.objects.all()) item = forms.IntegerField(min_value =0) and the template: {% extends "base.html" %} {% load crispy_forms_tags %} {% block title %}Table{% endblock %} {% block content %} <div class="table_order_form"> <h1>Order</h1> <form action="{% url 'table_order_view' %}" method="post"> {% csrf_token %} {{ form|crispy }} <button type="submit" class = "button table_order">PLACE ORDER</button> </form> </div> {% endblock %} And of course in the settings.py, I have declared: crispy_forms and CRISPY_TEMPLATE_PACK = 'bootstrap4' Problem 1: in forms.py, if the field item is a ModelChoiceField (the commented line), the form is out of whack, not "crispy" at all. But if I replace it with a usual form field such as IntegerField, the form is nicely formatted. Problem 2: in the template, I place a button right below the form, but when rendered, the button appears in parallel with the form, to its top right, and out of whack. Looking for some advice. Thanks. -

Django - Business users to fill a form that is to be sent as an email
Here is the problem I got. I need non-developers to send occasional marketing emails via the Django admin. Nothing too crazy or customized to justify paying for mailchimp and/or similar services, but more than just plain old text (which is currently working). Markdown formatting will do. I am aware of render_to_strings and using html files. But, that would require either manipulation of those html files by non-developers or doing a lot of them to fit the marketing needs. Currently it's a simple TextField that gets sent as is to the customers. Here is the code. Models from django.db import models from django.conf import settings from django.core.mail import EmailMessage class Subscriber(models.Model): email = models.EmailField(unique=True) def __str__(self): return self.email class Email_update(models.Model): subject = models.CharField(max_length=150) content = models.TextField() -- *Change to Markdownx or something similar?* created_at = models.DateTimeField(auto_now_add=True) def __str__(self): return self.subject + " " + self.created_at.strftime("%B %d, %Y") def send(self, request): subscribers = Subscriber.objects.all() email_list = [] for sub in subscribers: email_list.append(sub.email) email = EmailMessage( self.subject, self.content, "email@company", ["email@company.com"], email_list, ) email.send() Admin.py from django.contrib import admin from .models import Subscriber, Email_update # Register your models here. def send_email_update(modeladmin, request, queryset): for email_update in queryset: email_update.send(request) send_email_update.short_description = "Send selected Newsletters to … -

DRF, read/write permission for own profile
There is a write problem about own profile. I arrange some permissions and now super user can read and write all profiles. No problem at this part.

How to control the format of a duration field in django
I am making a simple clock in app. You push a button to punch in, and push it to punch out. I am trying to display the hours/mins between the out-punch and the in-punch. The code works, but I would like to change the output of the code. The output I am getting is something like this: I am pretty new to django and python in general, and would like to know how I can make this output something better, maybe like x:hours y:minutes or something like that. I definitely do not need the milliseconds. For clarity, the code is as follows: The model for the process is: class Punch(models.Model): employee = models.ForeignKey("timekeeper.User", on_delete=models.CASCADE, related_name="employee_punch") punchDate = models.DateField(default='2020-01-01') punchInTime = models.TimeField(default='01:01:01') punchOutTime = models.TimeField(null=True) worked = models.DurationField(null=True) def __str__(self): return f"Emp: {self.employee}, Timestamp: {self.punchDate}, IN: {self.punchInTime}, OUT:{self.punchOutTime} -- Worked: {self.worked}" The view code is: # Create your views here. def index(request): # The punch button was pushed if request.method == 'POST': r = request.POST.get('punch_button') # Record the punch on the Punch table if r == "PUNCH IN": Punch.objects.create( employee=request.user, punchInTime=datetime.now().time(), punchDate=datetime.now().date() ) elif r == "PUNCH OUT": now = datetime.now() p = Punch.objects.filter(employee=request.user, punchDate=now.date()).last() p.punchOutTime=now.time() # Converting punch times to … -

Django contenttype : Is it possible to create generic relation dynamically without explicitly defining GenericRelation(X) in a model?
Say if we want to define generic relation from Bookmart to TaggedItem, we would define in the model as follow: class Bookmark(models.Model): url = models.URLField() tags = GenericRelation(TaggedItem) and if we want more than one generic relations to models. we would have to explicitly define multiple GenericRelation(x) statements. I was reading Django permissions documentation and stumble upon this code: content_type = ContentType.objects.get_for_model(BlogPost) permission = Permission.objects.create( codename='can_publish', name='Can Publish Posts', content_type=content_type ) As far as I see from the docs, BlogPost doesn't explicitly specify its generic relation(s). How is it doing it? -
Django, ERP/CMS software and E-commerce site on different servers
hope someone can help me with this. I am new to python and django, but already took some tutorials on how to create your own ERP/CMS and eCommerce projects on Django. My questions are... or what I want to do is: I want to install the ERP/CMS in my own local server (also it's gonna be the admin part for the eCommerce site) Install the eCommerce site on a Webhosting server Suppose that you have a business and you manage your operation with the ERP/CMS (inventory, employee, invoicing, etc) software created on Django. Then you realize that you want to create a website and sell online. So you create your eCommerce site on Django and deploy it in your preferred Webhosting. Questions: Considerations: Have to be in 2 separate servers and database For security reasons, both databases can not see each other or have any relation between them. In a situation your site gets hack, your primary database(ERP/CMS) will not be compromised. On the eCommerce site, the info the will be upload are Category, subcategory, products(description, attributes, availability[quatity > 0]), image, selling price, client, address. I know that Django can handle multiple databases. What will be the easiest and efficient … -

Django Rest Framework & React Js ( Axios API Request ): After Incorrect authentication attempt, api returns 400
I'm creating a login system and basically, I have two inputs, one for username and the other for password. So when the user enters the correct credentials the API returns 200 response with some data but after incorrect credentials the django-rest-framework marks the request as 400 Bad Request and returns the response with 400 status code and no data, but this happens only when I'm sending a request from react js, after trying bad credentials from postman, the API returns: { "non_field_errors": [ "Incorrect credentials" ] } My Axios code: axios.post('http://192.168.0.29:8000/api/auth/login', { headers: { 'Content-Type': 'application/json' }, username: username, password: password }) .then((response) => { console.log(response.data); }) .catch(err => { console.log(err.data) alert('zjbs eroras') }); } -

Django: Is it possible to use a user model value as a db_table name

I get the following attribute error for zip_code even though I am able to store the users zipcode in that variable. zipcode =User.objects.filter(zipcode=User.zip_code) AttributeError: type object 'User' has no attribute 'zip_code' The second problem is identifying which user is logged in and assigning that value to the db_table = zipcode. Is there a better way to accomplish this? I would ultimately like for the db_table value to match the users zip code. -
Best hosting solution for Django application with low volume but large storage needs
I'm developing a Django app for an archaeological database. The actual traffic to the site will be very small (think 100 unique visitors a day) so using a cheap low powered VPS seems sufficient. But there is a very large amount of media (photos/pdfs) to host and make available. Looking at Digital Ocean and Amazon (EC2 + EBS) seems to make hosting large amounts of content very expensive. Is there an answer for low powered large volume hosting? -
django: Primary key issue when saving modelform into postgresql

Call data without for loop from database
how do I call data from the database without the for loop in a HTML file? I'm a beginnger and in all tutorials I could find they use the for loop. But I want to get a url from my database and post it only once in the HTML file, but I dont want to hardcode it in the file. So in my models.py my class looks like this class Weburl(models.Model): source = models.URLField(max_length=200) In my views.py I call this from django.shortcuts import render def index(request): songs = Songs.objects.all() contacts = Contacts.objects.all() url = Weburl.objects.all() context = {'songs': songs, 'contacts': contacts, 'url': url} return render(request, 'index.html', context) Of course you need to import the stuff in views.py. Now I can call the songs, contacts and url in a for loop. But I don't want to call url as a for loop. So what needs to be changed? Other question, does it make senses to save the songs and contacts in the context variable? If anyone knows what to do, it would be great. Thanks in advance.
