form.is_valid() not working as intended django
I am neew to django and I am trying to make an attendance system where the user can type their name and press clock in or clock out but when I test the code. But whenever I type a name and press clock In it does not save the name and time to the database. views.py: def home(response): form = CreateNewList() empName = employeeName.objects.all if response.method == "POST": form = CreateNewList(response.POST) if 'clockIn' in response.POST: if form.is_valid(): n = form.cleaned_data["name"] now = datetime.now() current_time = now.strftime("%H:%M:%S") t = Name(name = n, timeIn=current_time) t.save() return redirect('/') else: form = CreateNewList() return render(response, "main/home.html", context={"form":form, "empName":empName}) models.py: class employeeName(models.Model): employee = models.CharField(max_length=200) total_Hours_Worked = models.CharField(max_length=8, default="Empty") def __str__(self): return self.employee class Name(models.Model): name = models.ForeignKey(employeeName, null=True,on_delete=models.CASCADE) timeIn = models.TimeField() timeOut = models.TimeField(default=datetime.now()) date = models.DateField(auto_now=True) def __str__(self): return str(self.name) forms.py: class CreateNewList(forms.ModelForm): def __init__(self, *args, **kwargs): super(CreateNewList, self).__init__(*args, **kwargs) self.fields['name'].widget = TextInput() class Meta: model = Name fields = ['name'] home.html: <label>Enter Your Full Name:</label> {{form.name}} <datalist id="attendance"> {% for empName in empName %} <option value="{{empName.employee}}"> {% endfor %} </datalist> <button type="submit" name="clockIn" value="clockIn" class="btn btn-outline-primary">Clock In</button> I tried testing whenever I press the clockIn button to print something in the terminal … -
Django project run manage.py results in no module named django
I was working on a django project served as a backend for a small personal site, the built-in localhost server by django runs smoothly until I accidentally removed the app execution alias of python in windows 10(It just happened after done that, might not be the culprit). the situation is that when I use manage.py, it always results in a no module named "django" (venv) C:\Users\hongl\PycharmProjects\fluentdesign>manage.py runserver Traceback (most recent call last): File "C:\Users\hongl\PycharmProjects\fluentdesign\manage.py", line 11, in main from django.core.management import execute_from_command_line ModuleNotFoundError: No module named 'django' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "C:\Users\hongl\PycharmProjects\fluentdesign\manage.py", line 22, in <module> main() File "C:\Users\hongl\PycharmProjects\fluentdesign\manage.py", line 13, in main raise ImportError( ImportError: Couldn't import Django.

How to avoid n+1 queries in Django when you are not able to use select_related?
This is a problem I encounter quite often. Lets say I have three models: class CourseType(models.Model): name = models.CharField(max_length=50) class CourseLevel(models.Model): name = models.CharField(max_length=50) course_type = models.ForeignKey(CourseType, on_delete=models.CASCADE) class Course(models.Model): name = models.CharField(max_length=50) course_level = models.ForeignKey(CourseLevel, on_delete=models.CASCADE) def __str__(self): return "{}-{}: {}".format(self.course_level.course_type.name, self.course_level.name, self.name) If I were to iterate over Course.objects.all() and print the Course objects, that would be a n+1 query. This is easily solved by using select_related: Course.objects.select_related('course_level', 'course_level__course_type') The problem with this is I have to remember to use select_related every time. Its also ugly, especially if you have another model in there, like CourseDetails. One solution to this is to use a custom manager: class CourseManager(models.Manager): def with_names(self): return self.select_related('course_level', 'course_level__course_type') I can then use Course.with_names.all() and no longer need to add in the select_related every time. This has a major limitation - I can only take advantage of the manager when directly using Course. Very often I will iterate over Course objects through foreign keys, and again I will need to remember to use select_related and litter it all over my code. An example: class Student(models.Model): name = models.CharField(max_length=50) class StudentCourseEnroll(models.Model): student = models.ForeignKey(Student, on_delete=models.CASCADE) course = models.ForeignKey(Course, on_delete=models.CASCADE) Now if I want to print … -

IntegrityError while I am programmatically committing user to database - Django
In Django I am trying to create a log-in view that would accept a default username and default password. This would allow the log-in view to just accept the username 'test' and password 'test', this would allow the user to be authenticated without registration. The problem I am running into is utilizing create_user(). I have tried to create the variable default_user = User.objects.create_user(username = 'test', password = 'test') This just gives me an IntegrityError. I have tried to create code to handle the IntegrityError in a try/except block but continue to bump my head against the wall. Any help is appreciated. Thanks. views.py def index(request): if request.method == 'POST': form = LoginForm(request.POST) if form.is_valid(): cd = form.cleaned_data user = authenticate(request, username = cd['username'], password = cd['password']) if user is not None: if user.is_active: login(request, user) return HttpResponse('Authenticated '\ 'successfully') else: return HttpResponse('disabled account') else: return HttpResponse('Invalid Login') else: form = LoginForm() return render(request, 'server/index.html', {'form': form}) -
Django not sending data back to javascript fetch
I wrote this simple fetch post: document.querySelector('#retardo').addEventListener('click', function (e) { e.preventDefault(); let info = JSON.stringify({ retotitulo: document.querySelector('#retotitulo').value, retodescripcion: document.querySelector('#retodescripcion').value, retoprecio: document.querySelector('#retoprecio').value, }) let formData = new FormData(); formData.append('info', info); fetch(`http://127.0.0.1:8000/reto/crear`, { method: 'POST', body: formData, headers: { "X-CSRFToken": getCookie('csrftoken') } }) .then(response => response.json()) .then(result => { console.log(result) }) }) And this is how i manage the data from the server: def retocrear(request): if request.method == "POST": jsoninfo = json.loads(request.POST['info']) retotitulo = jsoninfo['retotitulo'] retodescripcion = jsoninfo['retodescripcion'] retoprecio = jsoninfo['retoprecio'] print(retotitulo) print(retodescripcion) print(retoprecio) return JsonResponse(jsoninfo) What works? The data is successfully sent to the server and I can see the variables printed on my terminal, also e.preventDefault(); works fine. What doesnt work? .then(result => {console.log(result)}) This line of code is not working. When I check my js console, nothing gets printed. Any idea why? Thank you in advance -

Webpack Error: Can't resolve style-loader from my webpack.config.js
I created a django project with django apps, one of which contains React. I am basically capturing the data in a Django Rest API then sending data to my REact and thus rendering "dynamic" views.

Django respond to a search result in a database from navbar
I'm working on a django app that has a database with various posts. These posts have names and ids. The ids are in sub urls like sitename.com/1. On every page of the django app, I have a navbar which was extended from base.html. The navbar has a search bar which is really a form submission. When I want to execute a search, I can take in the search data and use filters on it with the given database. However, the views.py has a function for each sub url. With each sub url that has a form on it, the function on views.py is handling the post request for the form. How am I going to handle the requests from the search bar form? Do I have to make a function that handles it and then copy paste a call for that function at the beginning of the functions for every other page I want to make? Is there an easier way to do this? I've heard of using @ but I don't know if that is the right use for this sort of problem. -

I'm using Django's default admin page for user management. Each user has a "department" field. On the filtration sidebar, users without a department could be accessed through that dash at the bottom of the list. the filteration list Now what we want is instead of creating a new "Unassigned" department and move those people in, is there any way to change that "-" to something else.

Django filter __in keep order and duplicates

Trying to add a form to a DetailView
I am writing a Detail View - and the form that is displayed is the particular Track that the user is adding/updating to the CD Entry (It's a CD Library application). The trick is I want to see everything else about the CD on the page as well as the form for the particular track. Having trouble figuring out how to get the form to be just the trac I am adding/updating. Basically you can enter a CD Title,Artist, and total time of the CD into the CD model. Then the Tracks are stored in the Track Model, with their Foreign Key being the CD they are on. While looking at a Detail View of the CD, the user can add or update a Particular track via a button.

Django - Query with multiple bool colums count true
I have a model with 100+ fields and all are bool values (true/false). How do I query this model and count the number of true values? Using django-aggregate-if is probably the closes I've come to an answer but it still requires using the field name. I'd like to avoid using the field name since there are so many fields. Everything I have tried has 1 thing in common...I can't seem to iterate over the query set without using the field name. I have also tried placing a count variable in the form to increase as form values are grabbed from the post request and sending the query set to another function to count. Essentially I am looking for something that will iterate over the query set and count true values regardless of the field name. -

How can I remove a particular item using a popup?

Django emptying display value after submitting form
I want my fields to show no value after submitting my django form, but I can't seem to find a way on how to do this.
