Template extends base.html but doesn't get the content of the sidebar
I have base_planner.html that contains a navbar and a sidebar. When I extend this base in any other template, both the navbar and sidebar are inherited, but the sidebar doesn't have any content that must be there. And I'm not getting any errors. The only template that has the sidebar content is the home page, which is merely a ListView html page (projectsmodel_list.html) containing one row: {% extends 'app_planner\base_planner.html' %} Here is my views.py (I want TestView to inherit the sidebar content): class ProjectListView(LoginRequiredMixin, generic.edit.FormMixin, generic.ListView): context_object_name = 'project_list' model = ProjectsModel form_class = ProjectsForm success_url = reverse_lazy('app_planner:planner_home') def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['create_project_form'] = ProjectsForm() return context def form_valid(self, form): project_name = form.cleaned_data['project_name'] project_author = self.request.user create_project_form_item = ProjectsModel(project_name=project_name, project_author=project_author) create_project_form_item.save() return super().form_valid(form) def form_invalid(self, form): return super().form_invalid(form) def post(self, request, *args, **kwargs): self.object_list = self.get_queryset() form = self.get_form() if form.is_valid(): return self.form_valid(form) else: return self.form_invalid(form) class TestView(generic.TemplateView): template_name = 'app_planner/test.html' Here is my urls.py: app_name = 'app_planner' urlpatterns = [ path('', views.ProjectListView.as_view(), name='planner_home'), path('test/', views.TestView.as_view(), name='test'), ] Here is the body of my base_planner.html: {% if user.is_authenticated %} <nav id='navbar' class="navbar navbar-expand-lg bg-white"> <div class="container-fluid"> <a id='logo' class="navbar-brand" href="{% url 'app_planner:planner_home' %}"><h3><b><span style="color:#FC5E5E;">Savvy</span> Planner</b></h3></a> <button class="navbar-toggler" type="button" … -
Insert multiple list in database using python django
Im confused on how can I insert multiple list bycolumn using a loop, let say the output what I want in database is something like this name percentage is_fixed_amount PWD 20 0 Senior 20 0 OPD 6 0 Corporators 20 0 Special 1 What I've tried but it's insert multiple data and it didn't reflect the actual data in database, Can somebody knows the solution? I appreciate any reply. discount = ['PWD','Senior Citizen','OPD','Corporators','Special'] discount_percentage = ['20','20','6','20',''] fixed_amount = [False,False,False,False,True] for dis in discount: for per in discount_percentage: for fix in fixed_amount: discount_val = Discounts(name=dis,percentage = per,is_fixed_amount =fix) discount_val.save() -
Dealing with circular dependencies on API endpoints
I am writing a new Django app with Django Ninja, to build an API. There is an app of "users" that contains an Organization model and a User model (that belongs to an organization). There is another app of "posts" that, for now, only has a Post model, that belongs to a user and an organization. So the "posts" API router is mounted on "/api/v1/organizations/{organization_id}/posts", and I can perform a complete CRUD over this. The problem comes when I want to retrieve the posts of an user. Suppose someone enters to a profile page, and then you want to get all data: user data, organization, posts count, all posts, etc. The more intuitive response would be like: "/api/v1/organizations/{organization_id}/users/xxxx" that returns all of this. But this means that the "users" app should know about "posts". And it introduces a circular dependency. What do you think? Have you been through the same problem? The above answer says it! -
Why I am not saving a wav file but .336Z file in the database after sending audio blob to server Django?
I am currently making a recording application with Recorder.js with Django. After pressing the 'Upload' button, it will send the audio blob to the server side, that is Django, and save in the database.

Why django form is submitted but the valued is null in the database?
We have a model called Column, and we want user to be able to create Table model based on Column model fields he created, we successfully do that using the method below: def create_table(request): columns = Column.objects.filter(user=request.user) fields = {} for column in columns: if column.field_type.data_type == 'number': fields[column.name] = forms.IntegerField() elif column.field_type.data_type == 'character': fields[column.name] = forms.CharField(max_length=20) elif column.field_type.data_type == 'decimal': fields[column.name] = forms.DecimalField(max_digits=20, decimal_places=10) elif column.field_type.data_type == 'image': fields[column.name] = forms.ImageField() elif column.field_type.data_type == 'boolean': fields[column.name] = forms.BooleanField() elif column.field_type.data_type == 'date': fields[column.name] = forms.DateField() TableForm = type('TableForm', (forms.Form,), fields) if request.method == 'POST': form = TableForm(request.POST, request.FILES) if form.is_valid(): table = Table() table.user = user=request.user for column in columns: setattr(table, column.name, form.cleaned_data[column.name]) table.save() return redirect('Table') else: form = TableForm() return render (request, 'create_table.html', {'form':form}) As you can see our view, our users can create Table model based on a Column model fields they created, but when the form is submitted, the value created from TableForm is null in the database, instead of showing us the object of the Table model created by a user, it is shown nothing, how can we solve this problem? the models: class Column(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) list_of_album = models.ForeignKey(Album, on_delete=models.CASCADE) name … -

django not receiving correct response? in front

How to implement dynamic filtering in Django ListView based on user input?
I'm working on a Django project where I need to display a list of items and allow users to filter the items based on various criteria. I'm using Django's generic ListView for displaying the items, but I'm not sure how to implement the dynamic filtering based on the user's input. Here's my current setup: models class Item(models.Model): name = models.CharField(max_length=100) category = models.CharField(max_length=50, choices=CATEGORY_CHOICES) price = models.DecimalField(max_digits=6, decimal_places=2) available = models.BooleanField(default=True) views: class ItemListView(ListView): model = Item template_name = "items/item_list.html" item_list.html {% for item in object_list %} <div class="item"> <h2>{{ item.name }}</h2> <p>Category: {{ item.category }}</p> <p>Price: {{ item.price }}</p> </div> {% endfor %} I'd like to allow users to filter the items by category, price range, and availability. What's the best way to implement this functionality in a Django ListView? Any guidance or examples would be much appreciated! -
Custimizing Django Admin (multiple registraion to a model)
I have a Django app with a master model that has a lot on detailed models. the detaled models are related to the master with foreign keys in each. I registered my master model in django admin and included all my detail models as "TabularInline" layout. My models.py looks like: # models.py file # class MasterModel(models.Model): # master model fields ... class DetailModel_01(models.Model): # detail model fields class DetailModel_02(models.Model): # detail model fields class DetailModel_03(models.Model): # detail model fields class DetailModel_04(models.Model): # detail model fields My admin.py looks like: class Detail_01_Inline(admin.TabularInline): model = Detail_01 class Detail_02_Inline(admin.TabularInline): model = Detail_02 class Detail_03_Inline(admin.TabularInline): model = Detail_03 class Detail_04_Inline(admin.TabularInline): model = Detail_04 @admin.register(MasterModel) class MasterModelAdmin(admin.ModelAdmin): inlines = [ Detail_01_Inline, Detail_02_Inline, Detail_03_Inline, Detail_04_Inline, ] The master model has too many fields, and too many inlines. therefore, not convienient to the users. I need to splet the inlines. can i register the master model more than one time in Django admin, and include part of the inlines each time ?? your ideas are so appreciated. Suhail
