Django - How to populate choices in a modelchoicefield with a field from another model filtered by logged in user
I'm trying to made a modelform with a modelchoicewidget which inherits its choices from another model than the model the modelform is connected to, and this selection is to be filtered by the current logged in user. The example below illustrates my intentions - let's say I have two different models where one model allows the user to register meal types (breakfast, dinner etc), and the other model allows the user to create specific meals based on those meal types, with the connecting variable being the title of the meal type. models.py: class Mealtypes(models.Model): author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) title = models.CharField(max_length=200, default='') description = models.TextField(default='') class Specificmeals(models.Model): author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) meal_name = models.CharField(max_length=200, default='') mealtype = models.CharField(max_length=200, default='') fruit = models.BooleanField(default=False) meat = models.BooleanField(default=False) dairy = models.BooleanField(default=False) forms.py from django import forms from django.core.exceptions import ValidationError from django.forms import ModelForm from .models import Mealtypes, Specificmeals class MealAdder(ModelForm): class Meta: model = Specificmeals fields = [ 'meal_name', 'mealtype', 'fruit', 'meat', 'dairy', ] widgets = { 'text': forms.Textarea(attrs={"style": "height:10em;" "width:60em;"}), 'mealtype': forms.ModelChoiceField(queryset=Mealtypes.title.filter(author='author')), 'fruit': forms.CheckboxInput(attrs={"style": "margin-left:350px;"}), 'meat': forms.CheckboxInput(attrs={"style": "margin-left:350px;"}), 'dairy': forms.CheckboxInput(attrs={"style": "margin-left:350px;"}), } I'm trying to play around with the ModelChoiceField to make it query the mealtypes from the Mealtypes model filtered … -
Read from file output to html template in django
How would the solution linked below be written in views.py to read from multiple files and output those various fields? I can make this work for one but if I try copy pasting f = open('path/text.txt', 'r') file_content = f.read() f.close() context = {'file_content': file_content} and changing the letters slightly to have unique versions it seems to break it...I am passing in unique variations not reusing "f" ex: h = open(BASE_DIR, 'path/tofile') file_content = h.read() h.close() context = {'file_contenth': file_contenth} I then pass in to the return return render(request, pathtohtml, {'file_content': file_content}, {'file_contenth': file_contenth} and that "breaks" it. I've tried a few variations of passing those variables in to no avail I used the solution found here Django: Display contents of txt file on the website -

I am testing django_python3_ldap library and using the same ldap server that I found in the tutorial (https://ldap3.readthedocs.io/en/latest/tutorial_intro.html), but there is something which I didn't get right to stablish the connection.

How to properly delete an instance of a model in Django
I am trying to delete an instance of an event from my calendar. I then want Django to redirect to the calendar page upon deletion of the event. In my views.py, I have defined an event_delete function: def event_delete(request, event_id=None): Event.objects.get(pk=event_id).delete() return HttpResponseRedirect(reverse("cal:calendar")) In my urls.py I have defined a url for deletion: from django.conf.urls import url from . import views app_name = "cal" urlpatterns = [ url(r"^index/$", views.index, name="index"), url(r"^calendar/$", views.CalendarView.as_view(), name="calendar"), url(r"^event/new/$", views.event, name="event_new"), url(r"^event/edit/(?P<event_id>\d+)/$", views.event, name="event_edit"), url(r"^event/delete/$", views.event_delete, name="event_delete"), ] and in my event.html, I have defined an a tag that takes in event_delete: <a class="btn cancel-button buttons login_btn" href="{% url 'cal:event_delete' %}" value="Delete" style="font-family:Optima;">Delete Event</a> When I try to delete an event, it redirects me back to the calendar page but I still see the event. If I try again, it gives me the error DoesNotExist at /event/delete/ Event matching query does not exist. When I check in my admin however, I still see the instance of the event. Please advice as to how I can resolve this. -

Particular Query from Queryset in Django
I have a model in Django called Accounts which has id, name, email, and balance fields. I want to retrieve the particular dataset when one visits the detail page. Say when I click on the details page I send through a string "name" which contains the name of the user the account is owned by. I am trying to obtain the particular query but to no avail. This is what the Queryset returns on Accounts.objects.all() ==> <QuerySet [<Account: UserA>, <Account: UserB>, <Account: UserC>, <Account: UserD>, <Account: UserE>, <Account: UserF>, <Account: UserG>, <Account: UserH>, <Account: UserI>, <Account: UserJ>]> I have tried Accounts.objects.values().get(id=id) but that provides a dictionary of id, user_id, and balance. I want to access the email of the user as well. I tried Accounts.objects.get(username=name) but it returns the error too many values to unpack. A way to do is Accounts.objects.all()[id] which is cheap and not dynamic since if we delete some users then it wont work. What am I missing here? or what is going wrong here? -
Django: submit only one form created with for loop
In my code I'm using a class CreateView with a ListView. I'm also using a for loop to show all the possible dates available (that are created in the StaffDuty models). My user should be able to just book a single date. My problem is that I'm not able to save a single appointment, I have to compile all the form showed in my list to be able to submit. How can I solve this? models.py class UserAppointment(models.Model): user = models.ForeignKey(UserProfile, on_delete=models.CASCADE) staff = models.ForeignKey(StaffDuty, on_delete=models.CASCADE) event = models.ForeignKey(Event, on_delete=models.CASCADE) event_name = models.CharField(max_length=255) date_appointment = models.DateField(null=True) def __str__(self): return self.event.name | str(self.staff.date_work) def get_absolute_url(self): return reverse('home') views.py class UserAppointmentAddView(CreateView): model = UserAppointment form_class = UserAppointmentForm template_name = "reservation.html" def form_valid(self, form): form.instance.user = self.request.user.userinformation def get_context_data(self, **kwargs): kwargs['object_list'] = StaffDuty.objects.order_by('id') return super(UserAppointmentAddView, self).get_context_data(**kwargs) html <div class="container"> <form method="post"> {% csrf_token %} {% for appointment in object_list %} <span>{{ form.staff }}</span> <span>{{ form.event }}</span> <span>{{ form.morning_hour }}</span> <span>{{ form.afternoon_hour }}</span> <div class="primary-btn"> <input type="submit" value="submit" class="btn btn-primary"> </div> </div> {% endfor %} -
How to inspect query generated by generic CreateView
I have a generic CreateView and it doesn't work as intended. In my db I have a table with composite primary key of two fields. When I try to create more then one instances of this table I get error message 'Order details with this Order already exists.'. Seems like query generated by CreateView is trying to update existing row, but I want it to create new one. It's all my assumptions and I wonder how can I check the exact query generated by Django's ORM. I suppose it's trying to update, not insert. How do I check that? Thanks. If needed, here's the view and model. class OrderDetailsCreateView(LoginRequiredMixin, CreateView): model = OrderDetails template_name = 'orders/orderdetails_create.html' form_class = OrderDetailCreateOrUpdateForm def get_form_kwargs(self, **kwargs): form_kwargs = super(OrderDetailsCreateView, self).get_form_kwargs(**kwargs) emp = get_current_users_employee(self.request.user) last_order = Orders.objects.filter(employee=emp, id=self.kwargs['pk'])[0] last_order_details = OrderDetails.objects.filter(order=last_order).values('product_id') already_selected_products = last_order_details form_kwargs['already_selected_products'] = already_selected_products form_kwargs['emp'] = emp return form_kwargs def form_valid(self, form): return super(OrderDetailsCreateView, self).form_valid(form) class OrderDetails(models.Model): order = models.OneToOneField('Orders', models.DO_NOTHING) product = models.ForeignKey('products.Products', models.DO_NOTHING) unit_price = models.FloatField() quantity = models.SmallIntegerField() discount = models.FloatField() class Meta: managed = False db_table = 'order_details' constraints = [ models.UniqueConstraint(fields=['order', 'product'], name='order-product') ] def get_absolute_url(self): return u'/orders/%d' % self.order.pk -
Running multiple django projects using docker and nginx
I am trying to do the following. I have 3 django projects (NOT apps) (can be more). Proj1: On port 8000, Proj2: 8001, and Proj3:8002 This is what I am trying to achieve: User visits : localhost:8000 All urls under Pr1: Respond User visits: localhost:8000/Pr2 All urls under Pr2: Respond User visits: localhost:8000/Pr3 All urls under Pr3: Respond Goal: Proj 1 is run with Docker and Nginx. Now I have 2 new projects to integrate. Every new sub project should be reached using only one main port (8000). But internally the request is directed towards the correct port of sub-project. Why this goal: Achieve micro-service style structure. Sub projects (2 & 3) can be reached only after authentication through Proj1. What have I tried: Honestly no clear idea where to start. Added new projects to docker-compose...they all work when visited by their own port(localhost:8001/Prj1) .. With nginx, tried adding a new server. No effect: server { listen 4445; location / { proxy_pass http://web_socket:8080; proxy_redirect off; } } -

Return daily sales value for the current month in Django
With the model below, I want to create a function that returns the details of daily sales for the current month. The details will be the total number of sales for each day and sum of sales for each day. I've tried using ExtractDay and annotate but I'm not getting the desired output or maybe I'm not doing it right class Stamping(models.Model): created = models.DateTimeField(auto_now_add=True) class Meta: abstract = True class Order(Stamping): user = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=300, unique=True) price = models.FloatField() quantity = models.IntegerField() In my location, the date is Tuesday, 2 November 2021. So the output should look like this <QuerySet [{'day': 1, 'count': 9, 'total': 100.0}, {'day': 2, 'count': 7, 'total': 80.0}]> And after today, I should also {'day': 3, 'count': 15, 'total': 200.0} and it keeps going till the end of the month then I'll start getting only the data for that month too -

Multiple ajax calls to populate fixed cell html table in django
———sorry for long question—— please share ajax-js-query-django code for the below requirement —-thanks a lot in advance… I have a functionality to achieve - its like giving a buyer ‘make your box’ kind of functionality - say a buyer lands in our ecom page with assorted items displayed along with radio-button having say 1. box-of-2 2. box-of-4 3. Box-of-6 So buyer selects box-of-2 and same page displays html box with just 2 cells. And below that all the items which can be clicked and this box-of-2 will be populated - say if buyer click item1 - then item1 gets placed in 1st cell of html table and then if he clicks on item2 then item2 gets placed in 2nd cell of html table. Now if buyer clicks on item3 - item3 gets placed in 1st cell of html table overwriting the item1 - so this way only two items will be in the html table. Now finally this box-of-2 is one commodity which can be added to cart by clicking on the add-to-cart button. Anyone can suggest some code snippets to achieve this with showing Empty box-of-n (html table) based on radio-button buyer selects Since the same page has all … -

Javascript not showing up on template in django

For example, the dropdown menu is in a weird format if I run the server. Another weird thing happening is that Main.js keeps being printed on the console. I believe this was initially because of the main.js file which had: console.log("Main.js"); However, even though I change it to the following: console.log("Something new for the console"); I still get Main.js printed out on the console. Moreover, if I put console.log("something") for my other javascript … -

remotely served Django service, does not return response for PATCH requests
I have deployed a Django rest framework service with multiple APIs on my Ubuntu 20.04 server with Gunicorn, everything works fine, but PATCH requests from outside the server do not receive a response, although the application receives the request and fully processes it.
