Django-admin startproject
I am new to django and I tried to create a project with django-admin startproject command. The tutorial I was referring to had no errors while going through this command but I get the following error. The tutorial and I are not doing it in any virtual environment. Though this error comes, the files and folder is created in the directory I am working in, how should I solve this error?

Django Admin doesn't recognise blank=True in model
When I try to edit a user (using a custom UserChangeForm) in the Django admin panel, validation insists that fields I have set blank=True in the model are required. I don't know where to begin solving this; I had the same issue with the CustomUserCreationForm but reverted to using the default which works as expected (asks for username, password1 & password2, creates the user with blank display_name, bio and profile_picture fields). models.py: from django.db import models from django.contrib.auth.models import AbstractUser class CustomUser(AbstractUser): display_name = models.CharField(max_length=30, blank=True, null=True) bio = models.TextField(blank=True, null=True) profile_picture = models.ImageField(upload_to='images/', blank=True, null=True) def save(self, *args, **kwargs): if not self.display_name: self.display_name = self.username super().save(*args, **kwargs) def __str__(self): return self.username forms.py: from django import forms from django.contrib.auth.forms import UserChangeForm from .models import CustomUser class CustomUserChangeForm(UserChangeForm): display_name = forms.CharField(label="display_name") bio = forms.CharField(widget=forms.Textarea) profile_picture = forms.ImageField(label="profile_picture") class Meta(): model = CustomUser fields = ("username", "email", "display_name", "bio", "profile_picture") admin.py: from django.contrib import admin from django.contrib.auth.admin import UserAdmin from .forms import CustomUserChangeForm from .models import CustomUser class CustomUserAdmin(UserAdmin): form = CustomUserChangeForm fieldsets = ( (None, {'fields': ('username', 'password', 'email', 'display_name', 'bio', 'profile_picture')} ), ) model = CustomUser list_display = ["username", "email",] admin.site.register(CustomUser, CustomUserAdmin) -
'NoneType' object has no attribute 'strip' - CS50W Wiki
I'm getting this error while trying to create a search function in Django. This is where I'm having trouble: If the query does not match the name of an encyclopedia entry, the user should instead be taken to a search results page that displays a list of all encyclopedia entries that have the query as a substring. For example, if the search query were ytho, then Python should appear in the search results. This is the view: def search(request): if request.method == 'POST': search_title = request.POST['q'] content = converter(search_title) if search_title is not None: return render(request, "encyclopedia/entry.html", { "entry": content, "entryTitle": search_title }) else: entries = util.list_entries() search_pages = [] for entry in entries: if search_title in entries: search_pages.append(entry) return render(request, "encyclopedia/search.html",{ "entries": search_pages }) And the HTML: <form action="{% url 'search' %}" method="POST"> {% csrf_token %} <input class="search" type="text" name="q" placeholder="Search Encyclopedia"> </form> Traceback: Traceback (most recent call last): File "C:\Users\anshi.virtualenvs\storefront-bp3LZ8Cr\lib\site-packages\django\core\handlers\exception.py", line 55, in inner response = get_response(request) File "C:\Users\anshi.virtualenvs\storefront-bp3LZ8Cr\lib\site-packages\django\core\handlers\base.py", line 197, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "D:\Python\Py Projects\CS50 attempt 00\wiki\encyclopedia\views.py", line 70, in search content = converter(search_title) File "D:\Python\Py Projects\CS50 attempt 00\wiki\encyclopedia\views.py", line 19, in converter html = Markdowner.convert(content) File "C:\Users\anshi.virtualenvs\storefront-bp3LZ8Cr\lib\site-packages\markdown\core.py", line 248, in convert … -
Adding widgets to django form does not update the forms
So I have a login form for which I am trying to edit the css attributes. However I cannot seem to find the correct solution. Below is my views.py, forms.py and html snippet accordingly. def index(request): context = {} if request.method == 'POST': form = LoginForm(data=request.POST) context['form'] = form logging.debug(form.is_valid()) logging.debug(form.cleaned_data) logging.debug(form.errors) if form.is_valid(): logging.debug("form valid") username = form.cleaned_data.get('username') password = form.cleaned_data.get('password') if authenticate(username, password): logging.debug("logged IN") messages.success(request, f' welcome {username} !!') return redirect('loggedIn') else: logging.debug("wrong!") messages.info(request, f'Password or Username is wrong. Please try again.') form = AuthenticationForm() return render(request, "index_logged_out.html", {"form": form}) class LoginForm(forms.ModelForm): class Meta: model = WebsiteRegistrant fields = ['username', 'password',] widgets = { 'username': TextInput(attrs={ 'class': "form-control", 'style': 'max-width: 300px;', 'placeholder': 'Username' }), 'password': PasswordInput(attrs={ 'class': "form-control", 'style': 'max-width: 300px;', 'placeholder': 'Password' }) } <form method="POST"> {% csrf_token %} <center> <div class="form-group" style = "margin-bottom: 10px; width: 300px"> {{ form.password }} </div> <div class="form-group" style = "margin-bottom: 10px; width: 300px"> {{ form.password }} </div> <button class="btn btn-primary btn-block fa-lg gradient-custom-2 mb-3" type="submit" style="width: 300px;">Login</button> </center> </form> Any idea what I am doing wrong or what I could fix in order to add the class name and attributes as I have defined in the form widget?

How to add data to Django's database by the click of a button using JS and AJAX
I'm trying to add data that I rendered on a page from an API endpoint, to my database when I click "Add to my records" button, as can be seen in the image below, and I'm only trying to store "Date and Country" into the database (my model table has only date and country) enter image description here I've seen many resources talking about how JS and AJAX are useful in this case but I'm lost with logic of it all. Is there any way someone could explain how it's supposed to be done. models.py from django.db import models class CountryData(models.Model): country = models.CharField(max_length=100) date = models.DateTimeField() def __str__(self): return self.country views.py def all_countries(request): first_response = requests.get("https://api.covid19api.com/summary").json() results = len(first_response["Countries"]) my_new_list = [] data_list = [] for i in range(0, results): my_new_list.append(first_response["Countries"][i]) # print(my_new_list) if request.method == "POST": if request.POST.get("country") and request.POST.get("date"): added_record = CountryData() added_record.country = request.POST.get("country") # 2022-12-19T08:53:48.179Z added_record.date = datetime.datetime.strptime( request.POST.get("date"), "%Y-%m-%dT%I:%M:%S.%fZ" ) added_record.save() return render(request, "allcountries.html") else: return render(request, "allcountries.html", ) context = {"my_new_list": my_new_list} return render(request, "allcountries.html", context) urls.py from django.urls import path, include from .views import home, all_countries urlpatterns = [ path("", home, name="home"), path("allcountries", all_countries, name="all_countries") ] allcountries.html {% extends '_base.html' %} {% … -
Upload file to database with file link

Setup logging of Celery in Django correctly - how?
Setting up celery on our production server seems to be more complicated than it should be - and the problem is logging. Our setup is like this: Server is Ubuntu 20.04.5 LTS We run Django 3.2.8 in it's own user and group named "django" The Celery process also has it's own user and group named "celery". Celery is set up as a service and logs to /var/log/celery In celery.py we have set djangoConf pointing to the main settings.py On startup Celery tries to touch a django-logfile and - missing the permissions to do so - returns an error: Dec 16 10:57:27 h2989788 celery[128418]: Usage: celery [OPTIONS] COMMAND [ARGS]...

Unable to install libapache2-mod-wsgi-py3
I am having some issues with wsgi and getting my django api up and running using apache. I think the issue is the mod_wsgi.so.

How can I add a dyno for my deployed app in Heroku?
I deployed the app for Heroku successfully but when I check status with 'heroku ps' command I receive information that I have no dynos on the app. The app is created in Django.

I would be grateful for any help. -

AUTH_LDAP_BIND_DN = "cn=ex-test,cn=user,dc=test,dc=ad" AUTH_LDAP_BIND_PASSWORD = "{PASSWORD}" AUTH_LDAP_USER_SEARCH = LDAPSearch("ou=sites,dc=test,dc=ad",ldap.SCOPE_SUBTREE,"(uid=%(user)s)") AUTH_LDAP_CONNECTION_OPTIONS = {ldap.OPT_REFERRALS: 0} AUTH_LDAP_USER_DN_TEMPLATE = "cn=%(user)s,ou=sites,dc=test,dc=ad" AUTH_LDAP_BIND_AS_AUTHENTICATING_USER = True AUTH_LDAP_GROUP_SEARCH = LDAPSearch("cn=priv-ex,ou=due,ou=ldap,ou=shared,dc=test,dc=ad", ldap.SCOPE_SUBTREE) AUTH_LDAP_GROUP_TYPE = GroupOfNamesType(name_attr='cn') AUTH_LDAP_USER_ATTR_MAP = { "first_name": "usersName", "last_name": "usersLastName", "email": "usersEmail" } AUTH_LDAP_REQUIRE_GROUP = "cn=DUE-MAIN,ou=DUE,ou=Applications,ou=Sharing,o=LDAP" ============== Problem It will not work for login. I do not know what I am doing wrong as I am following the docs precisely. Questions Q1: Is there anyway I can test the connection from a terminal or command line? Q2: I have seen the django-pyad package recommened with a settings.py that looks like # settings.py AUTHENTICATION_BACKENDS = [ 'django_pyad.backend.ADBackend', ] # AD configuration AD_LDAP_SERVER = "ad.example.com" AD_NT4_DOMAIN = "example" AD_SEARCH_DN = "OU=Users,DC=ad,DC=example,DC=com" Should I scrap what I did for the previous LDAP tree and go this route instead? Or can I re-use the previous LDAP connection code but change the values for AD like I am doing now? -

Mod_wsgi server will not start up
I am moving a currently working Django project to a new Red Hat server and upon moving the project, it's virtual env, and installing pip packages I started up the server how I always have and it worked fine. Going back to it a week later I enter in the web address of the django site and it times out. The mod_wsgi error log reads.

Getting data from another Foreign key - DRF
The relations of tables are shown in the picture. I have a main Table named Product. Two tables ProductImage , OrderedProduct have a Foreign key set to it. Now, I want to retrieve the image from OrderedProduct. How should I write the code for Serialization for it? Thanks Models.py Visualization This is my model.py file: class Product(models.Model): name = models.CharField(max_length=50) description = models.TextField() def __str__(self) -> str: return self.name class ProductImage(models.Model): product = models.ForeignKey( Product, on_delete=models.CASCADE, related_name='product_images') image = models.ImageField(upload_to="images/", null=True, blank=True) class OrderedProduct(models.Model): product = models.ForeignKey( Product, on_delete=models.CASCADE, related_name='ordered_products') quantity = models.IntegerField() Serializers.py class OrderedProductSerializer(serializers.ModelSerializer): product_name = serializers.CharField(source='product.name') product_price = serializers.FloatField(source='product.price') # product_img = >>> what should I do here? <<< class Meta: model = OrderedProduct fields = ('user', 'product', 'quantity', 'delivered', 'product_name', 'product_price', 'product_img') I've read the documentation, asked in some programming groups but couldn't find any good solution. I am expecting someone to give a reference that leads to the solution. -
How to upload an image to django from an html input file
I am developing a web service on django with frontend on react. I ran into a problem that I can't upload an image to django. Below is my component code where I'm trying to download it: export function ProviderRegistration(){ const[logoField, setLogoField] = useState() const token = useSelector((state) => state.user.token) const [cookie, setCookie] = useCookies(['auth']) const confirm = () => { axios.post(`/providers/?username=${cookie.auth.login}`, { photo : logoField }, { "headers" : { "Authorization" : "token " + token }}) .then(res => console.log(res)) .catch(err => console.log(err)) } return( <div className="registration-provider-container"> <div className="registration-title">Provider registration</div> <input type="file" className="registration-logo-add" onChange={(e) => setLogoField(e.target.value)}/> <button className="registration-confirm" onClick={() => confirm()}>Confirm</button> </div> )} And the endpoint processing this request class Providers(viewsets.ModelViewSet): filterset_class = ProvidersFilter queryset = Provider.objects.all() permission_classes = [IsAuthenticatedOrReadOnly, IsProviderPermission, IsOneToOneProviderPermission] def get_serializer_class(self): if self.action == 'list': return GetProviderSerializer else: return PutProviderSerializer def create(self, request): username = request.GET.get('username', '') user = User.objects.get(username=username).pk request.data.update({'user' : user}) print(request.data) return super().create(request) When I try to upload an image, django returns the following error: "The submitted data was not a file.

Using Model.objects.filter in Form prevents me from updating Model
I have a form setup like this where I use the values from TestModel to create a select field in a form. However if I want to update the TestModel to add a new column, Django gives me a psycopg2.errors.UndefinedColumn saying the new column is not found on the table and the stack trace points back to this form ModelChoiceField. Its not until I comment out this select that I am able to make the migration to the database. So my question is there a better way to setup this ModelChoiceField where I don't have to comment it out to update the underlying model on the database? I'm using Django 4.0 and python 3.8 for reference. class TestModelChoiceField(forms.ModelChoiceField): """ Overwriting model choice field attribute to use a different __str__ representation than the default model """ def label_from_instance(self, obj): return obj.test_field class TestForm(forms.Form): first_select = TestModelChoiceField( queryset=TestModel.objects.filter(model_attribute__isnull=False), initial=TestModel.objects.filter(model_attribute__isnull=False) .filter(test_field="Yes") .first() .team_id, label="Field One:", ) -
Creating a simple multiple users app in Django
So I've created 3 different users: admins, developers, and project managers. When I use the individual signup forms for each of these users and log out, it works, but then I when try to use the login form, it seems to me that it's acting like the signup form. Because when I input the same user details as the one I just created into the login form, it throws up the built-in error message, 'A user with that user name already exists' I'm not sure how to proceed from here. Here's what I have so far. models.py class CustomUser(AbstractUser): ACCOUNT_TYPE_CHOICES = ( ('admin', 'Admin'), ('developer', 'Developer'), ('project_manager', 'Project Manager') ) account_type = models.CharField(max_length=20, choices=ACCOUNT_TYPE_CHOICES) login and signupviews class LoginView(View): def get(self, request): # Render the login form form = LoginForm() return render(request, 'users/login.html', {'form': form}) def post(self, request): # Get the form data from the request form = LoginForm(request.POST) # Validate the form data if form.is_valid(): # Get the username and password from the form username = form.cleaned_data['username'] password = form.cleaned_data['password'] # Authenticate the user user = authenticate(request, username=username, password=password) # If the user is authenticated, log them in and redirect to the homepage if user is not None: login(request, … -

Need help about redirecting views in Django
I a beginner in learning Django and have met with an issue that need everyone help. I'm working on a web application for reading novels. I met with an issue that is related to views redirecting in Django. It's about how I can open the chapter page that I clicked on and read it perfectly normal but when I want to return to the novel index page by clicking on the link, I'm met with a NoReverseMatch error. I'll post my code below: This is what I configured in the urls.py: Then I created and configured the urls.py like this: And this is my views.py: The part that I've met with issue is an Html page for viewing chapter: What I have in mind is that by clicking on the url, I'll be redirected to the novel index page. But what happened is that I'm met with the NoReveseMatch error because the part that should have the slug that point to the index page is blank so I can't redirect to it. Anyone have an idea of what I did wrong ? Any helps or suggestions are appreciated
