Displaying queryset in django
I want the notes that is in my database to be displayed on the template. if(request.user): notes = Notes.objects.filter(user=request.user,url=costum_link) print(notes) print(costum_link) context.update( { "note" : notes } ) return render(request,'index/video.html' ,context) This is my template: <h2>Your Notes:</h2> {% for n in note %} <li>{{ n }}</li> {% endfor %} The template prints out Your Notes: ('This is the best note taking app I have seen on youtube\r\n',) (' I love it',) And this is not what I want it to print. I just want it to print the data. Can anyone please explain about this 'note' object and how to properly use it to solve my issue. -

What is the correct way of receiving data from post request in django.The request comes from pure javaScript using the fetch api. below is my code snippets: def change_group_name(request, pk): if request.method == 'POST': user = request.user name = request.POST.get('name', False) pk = request.POST.get('id', False) print('==========================================') print(name) print('============================================') I get an error when i try to print the name django.utils.dataStructures.MultiValueDictKeyError 'name' javascript async sendInfo(name ,id , csrf_token) { fetch('http://127.0.0.1:8000/accounts/group/detail/10/settings/change',{ method: 'post', credentials: "same-origin", headers: { 'Accept': 'application/json, text/plain, */*', 'Content-Type': 'application/json', 'X-CSRFToken':csrf_token }, body: {'id': JSON.stringify(id), 'name': JSON.stringify(name)} }) } -
Template doesn't exist
I'm new to django. I am trying to learn it by building a project. I wanna replace the django's localhost hompage with my homepage. But, I couldn't find views.py in main project directory.Why? By the way, I made a new 'views.py' and also created a templates forlder and put index.html in another directory inside templates named englishexchange. englishexchange/url.py from django.contrib import admin from django.urls import path from . import views urlpatterns = [ path('', views.index, name = 'index'), path('admin/', admin.site.urls), ] englishexchange/views.py from django.shortcuts import render def index(request): return render(request, 'englishexchange/index.html') and I put my templates directory in main project directory englishexchange. I know I can do that by making another app and maping the url to nothing like ' '. But I want them to have different home page than the main's static home page. The error I am getting is like Django tried loading these templates, in this order: Using engine django: django.template.loaders.app_directories.Loader: C:\Users\Sujeet Agrahari\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\contrib\admin\templates\englishexchange\index.html (Source does not exist) django.template.loaders.app_directories.Loader: C:\Users\Sujeet Agrahari\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\contrib\auth\templates\englishexchange\index.html (Source does not exist) I believe it's trying to find the templates in its default directory which is admin. How can I change this behavior so that it gets the templates from mian project directory? -

DateField and TimeField don't come out after adding to model class
I'm quite new to Python and Django. I'm setting up a new model class and I'm able to add appointments on the admin page, but here's the strange thing: I used to have a DateTimeFiled, which I changed to a separate DateField and a TimeField. But now I see neither my DateField nor my TimeField. Why is that, I don't understand it. I've done the migration, everything looks right. This is my model class: class Appointment(models.Model): patient = models.ForeignKey(User, related_name="appointment_patient", on_delete=False) date = models.DateField(auto_now=True) start_time = models.TimeField(auto_now=True) duration = models.DurationField(default=timedelta(minutes=30)) Before I made this change every property came out right, but now this happens: -

How to retrieve current Django user and feed it into a db entry
I am adding instances of Pets to a table: class Pet(models.Model): petName = models.CharField(max_length=100, default='My Pet') petImage = models.ImageField(default='default.png', blank=True) author = models.ForeignKey(User, on_delete=models.CASCADE, default=None) The code above is fine, however "User" on the last line gives me all the Users ever signed up on my app in a dropdown menu (when viewed as a form). I want the author (i.e. the User that is logged in) to be automatically associated with this new pet object. I dont know the ins and outs of the inbuilt auth_user database, so I dont know how to reference this specific instance of user, meaning the one who is logged in. I know that request.user on the other pages returns the user logged in, I just dont know how to feed that variable into this model. Any ideas? -

How to add friendships between users in Django
I'm doing a project for school. I'm creating a social media website with Django. I have problems with adding friendship between users. In the models I have extended the basic Django user.

Ajax post request cros-origin not working
I am trying to send some data to other domain, from my Django application via ajax post request. Here is my post request: var data = "id=somedata&src=somedata"; $.post('http://otherdomain.com/something.php', data, function(d){console.log(d)}) I get Reason: CORS header ‘Access-Control-Allow-Origin’ missing as expected, but i was told that i can catch the request and send it with python script with something(headers... i don't know), which then should work. The people that told me this were saying something about proxy but i don't remember what. But i still don't understand how can it work, and also i tried django-cors-headers but it doesn't work.Then i made my own middle-ware which adds header 'Access-Control-Allow-Origin','*' but when i looked at that request in developer tools it didn't have that header, only request which were 'inside' my django application. I still don't know if what i was trying to do was right and i only have problem in implementation, or i was doing everything wrong and should do something else. They send me this php-cross-domain-proxy, which is apparently what i am suppose to do, but in python. -

nginx gunicorn with docker: how to use multiple dockerfiles
I'm using the following example to build a django-postgres-nginx-gunicorn web server. I'd like to have separated folders for each container. The following structure of the project works correctly.

Django-Bootstrap formset not displaying group select as dropdown
I have a formset to display a selected subset of User information, and allow permitted people to edit it. Part of that is the users Group membership. The formset is created with modelformset_factory from django's built in User form. The problem I have is that the group field is not rendering as a dropdown. It shows all of the groups as a block, with the selected group highlighted. The template renders the form with <form action="{% url 'users:profiles' %}" method="post"> {% csrf_token %} {{ formset.management_form }} {% for form in formset %} <div class="row form-row"> {% bootstrap_form form show_help=FALSE %} {% buttons %} <button name="submit" class="btn btn-primary btn-sm">Submit</button> {% endbuttons %} </div> {% endfor %} </form> </div> I have tried rendering each field seperately with {% bootstrap_field %}, and the group as a <select>. That rendered correctly, but then trying to change on users detail caused every form to error. Is there a way to have a dropdown in a formset?
