csrf error while trying to delete an object with ajax
I have all the objects from my db rendered on my template by an ajax function. Near every object there's a button that should delete it from the db but since I'm working on Django it raise a csrf_token missing or incorrect error. I'm not using a form so I don't know how to include the csrf_token. var $orders = $('#orders') $.ajax({ type: 'GET', url: 'http://127.0.0.1:8000/MyApp/list-api/?format=json', success: function(orders) { $.each(orders, function(i, order){ $orders.append('<li>name: '+order.name+', drink: '+order.drink+'</li>') $orders.append("<button data-id=" +(order.pk)+" class='remove'>X</button>") }); }, error: function() { alert('errore caricamento ordini'); } }); $orders.delegate('.remove', 'click', function(){ $.ajax({ type: 'DELETE', url: 'http://127.0.0.1:8000/MyApp/list-api/' + $(this).attr('data-id') }); }); When I press a remove button a new request appears in the network panel of the browser, the response states :detail: "CSRF Failed: CSRF token missing or incorrect." The console gives a 403 forbidden error. Any help or hints are really appreciated. -

Automatically find tag names in RichTextField and link them to existing tags
I've created pages in Wagtail using 'MyPage' class and assigned Tags to them using Taggit. These tags appear ok and I can display them without issue. When clicked they load related articles on a listing page. I'm trying to find a way to automatically convert (li) list items (with the same name as my tags) (in RichFieldText) to these tags, so I won't have to manually assign links to each list item. I'm still fairly new to Django and Wagtail and haven't found anything in the documentation so far. Would anyone have a solution? // Where the RichFieldText is mylist_page.html {{ page.my_list|richtext }} // Displays my list If you need more of my code just let me know. Any help will be much appreciated.

Is there a way for vscode to recognise python django modules installed/available inside a vagrant vm so that I stop getting errors?
Python Django modules are already installed/imported in a Vagrant dev VM, but VSCode won't see them. How do I make VSCode see the imported Django modules inside a Vagrant VM? I'm working with a team and a complex already built Python/Django backend. We use a Vagrant vm to host the dev environment on our own personal machines for testing/debugging. I use VSCode but it gives me errors on all the imports on Django modules. They're available/installed in the Vagrant vm and the dev environment runs with no issues. It's just that VSCode and pylint are unable to see the modules are installed in the VM and can't import them. It's making debugging and coding difficult. from django.xxxx.xxx.xx import xxxx from django.xxxx.xxx.xx import xxxx I expect it to see that the modules are installed, but instead I get import-error from pylint saying unable to import 'django.xxxxx'. -

How to add Wagtail 'admin' menu to custom templates?
On templates that derive from the Wagtail Page model, there is a small Wagtail icon/menu in the lower right corner. This provides a quick way to edit the page and/or jump to the Wagtail Admin. However, this menu does not appear on custom view templates that are not derived from Wagtail Page model. How can I tell Wagtail to display the small menu on my frontend templates, so the pages have consistent navigation? -

How to cast a model into its parent?
I've made a class that, when you save a User, creates automatically the Person associated with the User like this: class Person(models.Model): user = models.OneToOneField(User, blank=False, null=False, on_delete=models.CASCADE) @receiver(post_save, sender=User) def my_post_save_user_handler(sender, instance, created, **kwargs): if created: # a User = physical -> create the associated person: Person.objects.create(user=instance, is_physical=True) Later I've made a Worker: class Worker(Person): job = models.CharField(unique=True, max_length=200) My problem is that I'd like to create a User associated with a Worker (= not a Person). When I do this: user = User.objects.create(username='test',) Worker.objects.create(user=user) I get this error: django.db.utils.IntegrityError: duplicate key value violates unique constraint "app_person_user_id_key" DETAIL: Key (user_id)=(2230) already exists. This is normal, because post_save is triggered when I create the User, and then a second time when I create the Worker. You might answer "just remove the auto generation of the Person" but I want for security reasons to always have a Person associated with a User. So is there a way to do something like: user = User.objects.create(username='test',) w = Worker(user.person) w.job = "the job" w.save() (I know that the previous code isn't working) or is there a way to "cast" a Person into a Worker? -

How to draw lines between selected options in two vertically placed list items in Django application?
We need to create an mapping tool application in Django. There are two categories, each containing approximately 5-10 items.

We should be able to draw line between the selected option from first category to selected options in second category on selection. Please let us know how can we do this with Python and Django?

'rest_framework.authtoken' ] I got a lot of failed tests (pytest), mainly 2 type of errors: status_code=403 You cannot access body after reading from request's data stream to solve status_code=401 error, I think i should add JSON Web Token Authentication here : REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_jwt.authentication.JSONWebTokenAuthentication', ), } still doesn't work ------------------------------ Captured log call ------------------------------- log.py 228 ERROR Internal Server Error: /graphql/ Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/django/core/handlers/exception.py", line 34, in inner response = get_response(request) File "/usr/local/lib/python3.7/site-packages/django/core/handlers/base.py", line 126, in _get_response response = self.process_exception_by_middleware(e, request) File "/usr/local/lib/python3.7/site-packages/django/core/handlers/base.py", line 124, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/usr/local/lib/python3.7/site-packages/django/views/decorators/csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) File "/usr/local/lib/python3.7/site-packages/django/views/decorators/csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) File "/usr/local/lib/python3.7/site-packages/django/views/decorators/csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) File "/usr/local/lib/python3.7/site-packages/django/views/generic/base.py", line 68, in view return self.dispatch(request, *args, **kwargs) File "/usr/local/lib/python3.7/site-packages/rest_framework/views.py", line 497, in dispatch … -
Render the images list inside a ModelChoiceField
I've developed a form, using Bootstrap4, for create a blog post. This form is linked at a model in which there are two ForeignKey: a FileField and an ImageField. If I use the default form rendering method({{ form.as_p }}) I can create a blog post but both the FileField and ImageField are rendered with the name of a single type of upload. I would like to see, instead of the name of the single image, the image. Then I've tried to use this: <div class="form-group mb-4"> <select class="form-control"> {% for img in geoform.image %} <option value="{{ img.pk }}"> <img class="img-fluid" src="{{ img.path }}" alt="{{ img.name }}"> </option> {% endfor %} </select> </div> but I see an empty list. This is the model: class GeoBlogFile(models.Model): name = models.CharField(max_length=70) path = models.FileField(upload_to='geoblog/documents/%Y/%m/%d') def __str__(self): return self.name class GeoBlogImage(models.Model): name = models.CharField(max_length=70) path = models.ImageField(upload_to='geoblog/images/%Y/%m/%d') def __str__(self): return self.name class GeoBlog(models.Model): title = models.CharField(max_length=70, unique=True) slug_title = models.SlugField(max_length=70, unique=True) contents = models.TextField(max_length=200) file = models.ForeignKey(GeoBlogFile, on_delete=models.CASCADE, related_name="related_file", blank=True, null=True) image = models.ForeignKey(GeoBlogImage, on_delete=models.CASCADE, related_name="related_image", blank=True, null=True) publishing_date = models.DateTimeField(default=timezone.now, blank=True) geom = models.PointField(srid=3857) def __str__(self): return self.title def get_absolute_url(self): return reverse("single_geopost", kwargs={"slug_title":self.slug_title}) This is the form: class GeoBlogPostForm(forms.ModelForm): title = forms.CharField( max_length=70, widget=forms.TextInput( … -
Adding a field to the Django User model
I need to add a model field "company" to the Django User model. I followed tutorials on how to do that but for some reason when I hit submit the browser just loops (keeps buffering) Not getting any errors in the terminal. It's hard to tell what's wrong if it just loops. this is what I've got: models: from django.contrib.auth.models import User class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) company = models.CharField(max_length=50, blank=True) def __str__(self): return self.user.username forms: from .models import UserProfile class CompanyFieldForm(forms.ModelForm): company = forms.CharField(widget=forms.TextInput(attrs={ 'class': 'form-control', 'autofocus': 'autofocus', 'placeholder': 'Company Name'}), label='') class Meta: model = UserProfile fields = ('company',) views: from django.contrib.auth import logout, login, authenticate from .forms import CompanyFieldForm def register(request): # KEEPS BUFFERING WHEN SUBMITTED ... WHY ? if request.method == 'POST': form = CreateUserForm(request.POST) company_form = CompanyFieldForm(request.POST) if form.is_valid() and company_form.is_valid(): user = form.save() profile = company_form.save(commit=False) profile.user = user profile.save() email = form.cleaned_data.get('email') plain_password = form.cleaned_data.get('password1') user = authenticate(username=username, password=plain_password) login(request, user) return redirect('/list') else: form = CreateUserForm() company_form = CompanyFieldForm() context = {'form': form, 'company_form': company_form, 'is_reg_page': True} return render(request, 'registration/register.html', context) -

How should i store multiple values of a model field in the database?
i am creating a stocks website using django. i want to display prices of different stocks in the webpage. i want store the prices of stocks at different dates. there are 100 stocks with 20 different prices for them. i want to display them at different intervals i want store these 20 different prices of these stocks in the database. so that i can select which price to display manually. i want to store the 20 different prices of the stock and display any one of them using querysets One solution i tried is i listed all the different prices in an excel file and whenever i wanted to display a different price i import it using python shell another solution was create a price1,price2....price20 field in the model. this is a very poor solution though i guess another solution i thought was i could create different databases for the different values and use the 'using' method to query them whichever is required from django.db import models # Create your models here. class Stocks(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length = 10,null='true',blank='true') ticker = models.CharField(max_length = 10) currentprice = models.FloatField() change = models.FloatField() lastprice = models.FloatField() updated = models.BooleanField(default='False',null='true') percent … -
Docker can't find file (and it exists)
I am doing a project in Django, I use PyCharm in Windows 8.1. To start the web server and the database I use Docker installed on Debian (Linux) through a virtual machine (do not install Windows Docker for compatibility problems). Upon entering the virtual machine, I mount the window folder on that machine: mount.vboxsf csuperior /tmp/csuperior I start the web container and db from the virtual machine and when I want to insert a breakpoint in the IDE, I get the following warning: pydev debugger: warning: trying to add breakpoint to file that does not exist: /tmp/csuperior/reunion/views.py (will have no effect) The strange thing is that the file exists and the path is correct. In fact I can modify it and the changes take effect. To configure the debug I followed the following tutorial: https://www.jetbrains.com/help/pycharm/remote-debugging-with-product.html#remote-debug-config (without the SFTP part, since the files are copy when I load the folder). In the "path mapping" I use the same folders as in the mount.vboxsf.
