I am trying to connect mysql to the back end of my project in Django When I use the command mysql -u root -p I receive this error: 'mysql : The term 'mysql' is not recognized as the name of a cmdlet, function, script file, or operable program.

How can I retrieve a value from my PostgreSQL database and print it in my html website?
I am trying to take information that is submitted by the user in a form, and make a query to my PostgreSQL database to retrieve the average cost of the selected repair. While I can retrieve the value, I can only do so in the scope of the (if request.method == POST) statement. Is there a way I can retrieve the cleaned_data from my form and filter the database entries outside of the scope? Here is the code in my views.py file that contains the problematic code: from django.http import JsonResponse from django.shortcuts import render, redirect, get_object_or_404 from .forms import ModelCreationForm from .models import Make, Model, Car, Repair, Cost def model_create_view(request): form = ModelCreationForm() if request.method == 'POST': form = ModelCreationForm(request.POST) if form.is_valid(): form.save() cost_data = getFormData(request, form) return redirect('model_add') return render(request, 'models/home.html', {"form": form}) def getFormData(request, form): year = form.cleaned_data['year'] make = form.cleaned_data['make'] model = form.cleaned_data['model'] repair = form.cleaned_data['repair'] form_data = Cost.objects.filter(year = year, make = make, model = model, repair = repair) return render(request, 'models/home.html', {"cost": form_data[0]}) def model_update_view(request, pk): car = get_object_or_404(Car, pk=pk) form = ModelCreationForm(instance=car) if request.method == 'POST': form = ModelCreationForm(request.POST, instance=car) if form.is_valid(): form.save() return redirect('model_change', pk=pk) return render(request, 'models/home.html', {'form': form}) def load_models(request): … -

Django: making user email unique=True is causing a problem
I made email field unique in the user model because I don't want users sharing same email. But now the problem is that when I created the first user without email address and then tried to create a second user without email address, I got error message about user with email already existing whereas there's no user yet with email address. I edited the first user and added an email address before I could successfully create a second user without email address. Please what am I doing wrong? I want to be able to create several users without email address. -

Why does pagination in django half working?
I tried to implement pagination in django using ajax. But for some reason my pagination is half working. That is, the buttons work, but nothing happens when you go to another page.

React app creating cart but not getting cart from django backend
Gooday everyone I'm working on an ecommerce project and I'm trying to build the cart for the unauthenticated users.

ModuleNotFoundError: No module named 'settings' for any django project
I have been studying Django for some time and have been working on a project. Everything was fine until yesterday when I was studying a new topic, saved the project and shut down my PC. There were no errors or anything. Today, when I tried to run my project using the command "py manage.py runserver", I received an error "ModuleNotFoundError: No module named 'settings'". I spent enough time trying to solve this problem and assumed that the error was in my project. I couldn't solve it and decided to create a completely new project in a new virtual environment. To my surprise, the same error occurred in this completely new project as well. I thought that I might be doing something wrong, so I repeated the project creation on my laptop, and everything worked as expected with no errors. I tried reinstalling PyCharm and Python, but it didn't help. I don't think I can continue using Django on this PC anymore... I don't know what data may be needed to solve this problem, so I will provide at least something. These are the data from the project that was just created.

I have a view that is responsible for bulk updating objects, since DRF doesn't provide any generic view for that I proceed with this approach.

How to insert values into a form from another table?
I have two tables. A first table contains a list of offices and a second table contains a list of cartridges. When I create the cartridge, it's required to write the office. But it is necessary that in the form of creating a cartridge in the office selection there should be a list from the Offices. How to do it? For example, there is the list: Offices ID name 1 A11 2 A11-1 3 A12 4 A13 5 A13-2 My code: Models.py class Office(models.Model): name = models.CharField('name', max_length=255) def get_absolute_url(self): return reverse('office_list') class CartridgeList(models.Model): office = models.CharField('office', max_length=255) uniquenumber = models.CharField('unique number', max_length=255) status = models.CharField('status', max_length=255) def get_absolute_url(self): return reverse('cartridge_list') forms.py class CartridgeListForm(forms.ModelForm): class Meta: model = CartridgeList fields = ('office', 'uniquenumber', 'status') widgets = { # Now I write the office here, but it's required to have a ready list from Office Model (A11, A11-1, A12, A13, A13-2) 'office': forms.TextInput(attrs={'class': 'form-control'}), 'uniquenumber': forms.TextInput(attrs={'class': 'form-control'}), 'status': forms.TextInput(attrs={'class': 'form-control'}), } Views.py: class AddCartridgeListView(CreateView): model = CartridgeList form_class = CartridgeListForm template_name = 'add_cartridge.html' -
Populate Django Model with for-loop
I have a model Task which I want to populate with a for loop. In a list I have the tasks that should be passed into the model. My model has actually more than three tasks (Below I have shown only three). The list will also have varying number of entries. The list can also have only one task. tasks = ['first task', 'second task', 'third task'] class Task(models.Model): ad = models.OneToOneField(Ad, on_delete=models.CASCADE, primary_key=True, blank=True, null=False) task1 = models.CharField(max_length=256, blank=True, null=True) task2 = models.CharField(max_length=256, blank=True, null=True) task3 = models.CharField(max_length=256, blank=True, null=True) def __str__(self): return f'Tasks for {self.ad}' My approach looks like this: task_obj = Task.objects.create( ad = ad ) for idx, t in enumerate(tasks): task_obj.f'task{idx+1}' = t Basically this part f'task{idx+1}' should not be a string, but the actual variable of the model. Is this even possible? Or does an other way exist I am not aware of? -
Implement search bar in django
I want to implement two things: User page from URL: If I enter a URL like '.../username', I am taken to that page provided it exists. For that I mapped 'str:username' to user_profile view.

Next is implementing a search bar where I will enter a username and submit to call the same function passing the input value as the argument to that view function. I tried various method like {% url 'user_profile' username=username %}. Used various if else conditions but still I am unable to make it. -

As I have warnings phobia so to remove them I tried to make them aware of time zone using the function make_aware timestamps = [ make_aware(t) for t in timestamps ] Now after this time values are changed for example if original datetime was "2023-03-17 06:45:00" then after make_aware it changes to "2023-03-17 10:45:00" My question is do I really need time zone support? is it mandatory in my case? what if I disable the time zone support? can I still parse the datetime using make_aware but without changing the time string?

How can I make cloned select2 fields working?
I have two select2 fields that are working as dynamic search engine inside a form. I need to clone this form so the user can add multiple entries and filtering inside these two fields that are working as search engine. HTML: <div class="form-group"> <label>{% trans "Departure Aerodrome" %}</label> <select class="form-control adep" name="adep" id="adep"> {% if not base_airport %} <option disable="">{% trans "Choose one Airport" %}</option> {% else %} <option value="{{base_airport.icao_code}}">{{base_airport.icao_code}} - {{base_airport.name}} </option> {% endif %} </select> </div> <div class="form-group"> <label>{% trans "Arrival Aerodrome" %}</label> <select class="form-control ades" name="ades" id="ades"> {% if not base_airport %} <option disable="">{% trans "Choose one Airport" %}</option> {% else %} <option value="{{base_airport.icao_code}}">{{base_airport.icao_code}} - {{base_airport.name}} </option> {% endif %} </select> </div> <div class="col"> <button class="btn btn-primary" id="addFlightBtn">{% trans "Add New Flight" %}</button> </div> My form is inside a forloop, so there can be 1 item as many other items. So I initialize the select fields with this function: $(document).ready(function () { searchAirports(".adep", "adep-"); searchAirports(".ades", "ades-"); }); function searchAirports(className, idName) { $(className).each(function (index) { var id = idName + index; $(this).attr("id", id); $("#" + id).select2({ ajax: { url: "/flight/search_airports", dataType: "json", data: function (params) { return { search_value: params.term, // search term }; }, processResults: function (data) …
