How to background Django API with scalability in AWS?
I have an API in Django (restframework) actually hosted in a Elastic Beanstalk in single docker container template Web server using LoadBalancer and AutoScale provided by AWS EB. I want to background API because it deals with many requests hits in the same sec causing many 5xx http errors. After some research I found that Celery can make this work for me using SQS, but I don't know how to develop this scenario (I can run the API with Celery workers locally, but I don't know how to make this on AWS EB or even in a docker-compose). Should I use Elastic Beanstalk Worker environment and/or docker-compose? Can I put Django and Celery in a docker-compose and deploy it on EB Web or I need to change environment tier in this case? What kind of changes I need to make in my actual project (Docker-Django-EBWeb) to background tasks? Note: I need some configs in container image to integrate past Oracle 11g DB (instant client 11g + cx-Oracle5.3) -

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.

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? -

Here is the code I got from the previous developer. view ITEMS_ON_PAGE = 10 class BlogViewMixin(ListView): queryset = Article.objects.all() context_object_name = 'articles' category = None def get_queryset(self, *args, **kwargs): queryset = super(BlogViewMixin, self).get_queryset(*args, **kwargs) if (self.kwargs.get('page')) == '1': raise Http404 page = self.kwargs.get('page', 1) category = self.kwargs.get('category', None) if category: category = get_object_or_404(Category, url=category) queryset = queryset.filter(category=category) self.category = category paginator = Paginator(queryset, ITEMS_ON_PAGE) try: queryset = paginator.page(page) except EmptyPage: queryset = [] #Here I tried to raise 404 return queryset def get_context_data(self, **kwargs): context = super(BlogViewMixin, self).get_context_data(**kwargs) context['current_page'] = self.kwargs.get('page', None) if context['current_page']: context['current_page'] = int(context['current_page']) context['current_category'] = self.category context['categories'] = Category.objects.exclude(is_green_button=True) context['marked_category'] = Category.objects.filter(is_green_button=True).first() context['SITE_URL'] = settings.SITE_URL context['pages'] = Page.objects.filter(show_on_main_menu=True, is_draft=False).order_by('order') return context class BlogView(BlogViewMixin): template_name = 'blog/index.html' Trying to throw an error in if not queryset: raise Http404 but goes into recursion. I rewrote the middleware for processing 404. Maybe the reason is in it. middleware import … -

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. The first category should be a single select option and second is the multiple select option. After choosing a element from first category, the user will select multiple options from the second category. 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? Also let us know if we need to use any additional tool with Python? We tried to do this by using Python and Django. But we are facing problem in drawing that line on selection. -

I'm working on a Django project with Graphql API, at some point I needed to throttle mutations so I used graphene-django-extras library to achieve that. In order to take advantage of graphene-django-extras throttling feature, I use AuthenticatedGraphQLView instead of ExtraGraphQLView and I added djangorestframework library and add this to my ins stalled apps : INSTALLED_APPS = [ ...

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 ...
