Using Default UserCreationForm does not show error if the passwords do not match
Using Default UserCreationForm from django.contrib.auth.forms does not show error if the passwords do not match. I do not want to create a custom model. Here is the code from my views.py file from django.contrib.auth.forms import UserCreationForm from django.shortcuts import render # Create your views here. def register(response): if response.method == "POST": print(response.POST) form = UserCreationForm(response.POST) if form.is_valid(): form.save() else: print(form.errors) form = UserCreationForm() return render(response,"register/register.html",{"form":form}) register.html code <html> <head> <title>Register </title> </head> <body> <h1>This is the Registration page</h1> <form method="post"> {% csrf_token %} {{form.as_p}} <button type="submit">Submit</button> </form> </body> </html> I thought the message would be automatically displayed. Am I missing something? Edit: None of the error message are being displayed like password length < 8, all numeric passwords, etc. -
Can't access to public IP of django docker container
I can access the container with these curl commands: curl http://localhost:8000/api/health/ curl http://127.0.0.1:8000/api/health/ But I can't access it with public IP address: curl http://xx.xxx.xxx.xxx:8000/api/health/ curl: (7) Failed to connect to xx.xx.xxx.xxx port 8000 after 0 ms: Connection refused I used this command to run the container: docker container run -d --network=host -p 8000:8000 my-central-api Dockerfile has this line: CMD [ "python3", "manage.py", "runserver", "0.0.0.0:8000"] I am running this container on an EC2 instance. I set up the security group and NACL. So I think it is related to docker configuration. Why I can't access to port 8000 with public IP? -

Heroku adds whitespace characters to django template javascript code
I'm trying to combine python and javascript code in django template to update page after every keyup event (like in a browser). I have a list of teachers with name and surname which I want to display if it matches pattern given by the user. While everything is fine on localhost, after deploying on heroku there is a syntax error: Uncaught SyntaxError: Invalid or unexpected token Here is a fragment of my teacher.html file, where python teachers is QuerySet passed from views.py during rendering and str is a pattern taken from entry, earlier in javascript function get_names(str){ let teachers = []; {% for teacher in teachers %} var name = "{{teacher.name}}"; if (name.includes(str)) { teachers.push("{{teacher|safe}}"); } {% endfor %} return teachers; } Here is output of my localhost js code var name = "John"; if (name.includes(str)) { teachers.push("John Kowalski"); } And here is output of heroku server var name = "John"; if (name.includes(str)){ teachers.push("John Kowalski <-- Error occurs here "); } More interesting is the fact, that for some names it works, but mostly it doesn't.

How to add two form fields (one shown and one not) to a model field
I have a Spent model class that holds the name of where the user spent money at, how much, the reason as to why they spent, and a total amount spent. The total amount spent does not show up on the form in the template just the name, place and how much was spent (no need for the total amount to be shown). I'm having trouble figuring out how to update the total amount spent. I would like to have the total amount spent keep track of how much the user has spent in total. modles.py from django.db import models from django.contrib.auth.models import User class Bills(models.Model): name = models.CharField(max_length=25) amount = models.FloatField() due_date = models.DateField() user = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.name class Budget(models.Model): income = models.FloatField(default=0.00) budget = models.FloatField(default=0.00) user = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.user.username class Spent(models.Model): name = models.CharField(max_length=25) amount = models.FloatField(default=0.00) reason = models.TextField(default="") total_spent = models.FloatField(default=0.00) user = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.user.username forms.py from django import forms from .models import Bills, Budget, Spent class DateInput(forms.DateInput): input_type = 'date' class AddBillForm(forms.ModelForm): class Meta: model = Bills fields = ['name', 'amount', 'due_date'] widgets = { 'name': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Enter bill name'}), 'amount': … -
Django User does not update when saved?
I cannot get the default User model or my created Agent model to update. Below is my admin.py, forms.py, models.py, urls.py, views.py, and my edit_profile.html. I know it must be silly, but I've got three good days working on this. The HTML page tries to edit both the "EditProfileForm" and the "MoreInfoForm." The EditProfileForm uses the built-in User model, while the MoreInfoForm is my model that extends the built-in User model. As a note, the MoreInfoForm also contains an Image that I want to be able to update. When I submit the form, I get a POST request, but when I view the profile, it doesn't contain any changes. admin.py class AgentInline(admin.StackedInline): model = Agent can_delete = False verbose_name_plural = 'agent' class UserAdmin(BaseUserAdmin): inlines = (AgentInline,) admin.site.unregister(User) admin.site.register(User, UserAdmin) forms.py class RegisterUserForm(UserCreationForm): email = forms.EmailField(widget=forms.EmailInput(attrs={'class': 'form-control'})) first_name = forms.CharField(max_length=50, widget=forms.TextInput(attrs={'class': 'form-control'})) last_name = forms.CharField(max_length=50, widget=forms.TextInput(attrs={'class': 'form-control'})) class Meta: model = User fields = ('username', 'first_name', 'last_name', 'email', 'password1', 'password2',) def __init__(self, *args, **kwargs): super(RegisterUserForm, self).__init__(*args, **kwargs) self.fields['username'].widget.attrs['class'] = 'form-control' self.fields['password1'].widget.attrs['class'] = 'form-control' self.fields['password2'].widget.attrs['class'] = 'form-control' class MoreInfoForm(forms.ModelForm): agent_phone_num = forms.CharField(max_length=10, required=True, help_text='Enter a 10 digit # without spaces or dashes', widget=forms.TextInput( attrs={'class': 'form-control'})) agent_mls = forms.CharField(max_length=6, required=True, help_text='Enter your 6 … -
Django - "return render(...)" doesn't work in a view that interacts with an ajax request
I want to solve this task: I click a button on the first page and after that my view creates a chat room and redirects me to the chat page. I decided to use ajax request for this task, but I have a problem, my view works until line return render(request, 'chat/chatroom.html'), the chat room is created, but the chat/chatroom.html page doesn't open, I don't understand why.

Django DateTimeField default not affecting Time

Forbidden (CSRF token missing or incorrect.) how to send CSRF token from frontend to backend?
I have a Django project, where I need to send a date string from frontend to backend. At frontend I am using the javascript fetch method async function getCustomerInDeliveryDate(deliveryDate : String) { const response = await fetch('getCustomerInTripDate', { method : 'POST', headers : { 'Content-Type' : 'application/json', }, body: JSON.stringify({ deliveryDate : deliveryDate }), }); return response } From Django backend I currently implemented a simple method that returns a string back to frontend class GetCustomerInTripDate(LoginRequiredMixin, View): def post(self, request, *args, **kwargs): print('Backend received call from front end!!!!!!!!!!!!!') return JsonResponse({'data': ['hello', 'world']}, status = 200) The error that I receive when I try to send to backend is Forbidden (CSRF token missing or incorrect.): /staff/getCustomerInTripDate I am not sure how to send the csrf token. The research I have done so far all indicated that credentials should be set as "same-origin", and I have tried it but still get the same error. -

custom pagination of limit and page in Django Rest Framework
I wanted to create custom paginations for this get_queryset. get_queryset = Comments.objects.filter(language_post_id=post_in_lang_id,is_post_comment=True).order_by('-created_on')[offset:offset+limit] I want to change the offset value whenever the page_no updates. Suppose someone enters page_no=1, so offset must be 0, and when enters 2, so offset should be 10, and so on. Every time page_no updates, it should update the offset value accordingly. like ?page_no=3: get_queryset = Comments.objects.filter(language_post_id=post_in_lang_id,is_post_comment=True).order_by('-created_on')[offset:offset+limit] # [ 20 : 20 + 10 ] -

How can you omit empty django-filter params in url?
I am using django-filters to filter my queryset, I am wondering whether it is possible for the library to omit empty fields when generating a filtered URl.
