how to fix "invalid keyword argument for this function" in ModelSerializer
I'm working on ModelSerializers their is a non-model field that is uploaded_files = serializers.FileField(required=True, source='files') in BlogSerializer. The uploaded_files does not belong to BlogModel. When is try to upload it gives me 'files' is an invalid keyword argument for this function i know files is not a field in BlogModel but i tried to add a property method files(self): in BlogModel which did not work either. models.py class BlogModel(models.Model): BLOG_STATUS = ( ('PUBLISH', 'Publish'), ('DRAFT', 'Draft'), ) blog_id = models.AutoField(primary_key=True) user = models.ForeignKey( User, on_delete=models.CASCADE, related_name='blogs') title = models.CharField(max_length=255) content = models.TextField(blank=True, null=True) status = models.CharField(max_length=7, choices=BLOG_STATUS) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Meta(): db_table = 'blogs' verbose_name = 'Blog' verbose_name_plural = 'Blogs' def __str__(self): return self.title @property def files(self): #here is the property i added return 'do something' serializers.py class BlogFilesSerializer(ModelSerializer): created_at = serializers.SerializerMethodField() updated_at = serializers.SerializerMethodField() class Meta: model = BlogFilesModel fields = ('blog_files_id', 'blog', 'path', 'created_at', 'updated_at') extra_kwargs = { 'path': { 'error_messages': { 'blank': 'File is required' }, } } class BlogSerializer(ModelSerializer): blog_files = serializers.SerializerMethodField() uploaded_files = serializers.FileField(required=True, source='files') blog_created_at = serializers.SerializerMethodField(read_only=False) class Meta: model = BlogModel fields = ('blog_id', 'user', 'title', 'content', 'status','blog_files', 'blog_created_at', 'uploaded_files', ) Hope is have explained my problem well.

Django Cart - multiple configuration options for a product
I want to create a Django web-application where users can add items to a cart. Without the models Colour and Size this works so far. My Problem is, that i can not figure out how to implement the configuration-options (for example) Colour and Size the right way. I added both "Options" with a Many-to-One relationship. I now can add multiple colours and sizes for a Product, but do not know how to save the choosen "Option" in an CartEntry This is what i got so far: from django.db import models from django.contrib.auth.models import User class Product(models.Model): name = models.CharField(max_length=256) price = models.DecimalField(max_digits=6, decimal_places=2) def __str__(self): return str(self.name) class Colour(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE, related_name="rel_colour") option = models.CharField(max_length=24) price = models.DecimalField(max_digits=6, decimal_places=2) def __str__(self): return str(self.colcour) class Size(models.Model): product =models.ForeignKey(Product, on_delete=models.CASCADE, related_name="rel_size") option = models.CharField(max_length=24) price = models.DecimalField(max_digits=6, decimal_places=2) def __str__(self): return str(self.size) class Cart(models.Model): user = models.ForeignKey(User, null=True, blank=True, on_delete=models.CASCADE) products = models.ManyToManyField(Product, blank=True) updated = models.DateTimeField(auto_now=True) timestamp = models.DateTimeField(auto_now_add=True) def __str__(self): return str(self.id) + ' - ' + str(self.user) class CartEntry(models.Model): product = models.ForeignKey(Product, null=True, on_delete=models.CASCADE) cart = models.ForeignKey(Cart, null=True, on_delete=models.CASCADE) quantity = models.PositiveIntegerField() def __str__(self): return str(self.quantity) + ', ' + str(self.product.name) -
How Can I implement custom authentication in django for user login
I want to implement custom login authentication in Django. I do not want to use Django's inbuilt authentication system because it is not working. I have a model named Doctor and I want to fetch the data from the Doctor model for login authentication. I have set my default database as MySQl database. I have tried some code but it didn't work for me. views.py def login(request): if request.POST: username = request.POST.get('username') password = request.POST.get('password') user = authenticate(username=username, password=password) if user is not None: login(request,user) return render(request,'welcome1.html') #success else: #Invalid login return render(request, 'login.html',{ 'error_message':'Invalid Credential' }) return render(request, 'login.html') models.py class Doctor(models.Model): initial_name = models.CharField(max_length=8) first_name = models.CharField(max_length=20, unique=True) last_name = models.CharField(max_length=20, unique=True) hospital_name = models.CharField(max_length=20) username = models.EmailField(max_length=50) password = models.CharField(max_length=50) address = models.CharField(max_length=1024) zip_code = models.CharField(max_length=12) dob = models.DateField(max_length=8) gender = models.CharField(max_length=10) phone_number = models.TextField(max_length=10) def __str__(self): return self.initial_name My expected output should be "when I will put wrong Email & password, it will show an error" But it is automatically redirecting to my home page, if i put wrong eail or password. -

Django URl routing for email
Hi I am relatively new to Django, I am making a web based todo list. Upon following some online tutorials I was able to make the list. One of the tasks that im trying to achieve is the ability to send the list as an email with the status. I created a from in the form.py, created a sendMail view in views.py, linked these to the URL and added sendmail.html in the templates. But when I am clicking on the send mail anchor tag in index.html it redirects and says "Page Not Found". I am pretty confident that it has something to do with incorrect URL routing as the list works perfectly but the email functionality doesnt. I am also trying to figure out how to add the elements from the Todo list and send it using send_mail(). Here's the HTML file {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>ToDo App</title> <link href="https://fonts.googleapis.com/css?family=Oswald" rel="stylesheet"> <!-- Bootstrap CSS --> <link rel="stylesheet" href="{% static 'todo/bs/css/flatly.min.css' %}" /> <link rel="stylesheet" href="{% static 'todo/styles.css' %}" /> </head> <body> <div class="container-fluid" id="wrapper"> <div class="row"> <div class="col-lg-4 col-lg-offset-4" id="content"> <h2> {{ mydate|date:"D, d M Y"}}</h2> … -
ArrayField doesn't get updated?
I'm trying to check if a lesson has been done (by checking if the page has been visited once on a logged account). I've been trying to check if the page has been visited. If not, the ID should be added in the array of visited pages. I'm checking all the possible situations (or at least the one I could think of) and when I have to, I add another lection.id to the array of accessed lessons. After priniting this array everytime, I saw that the lesson id gets added, but not in the database. (if I check the DB or if I change the page the lesson id disappears) views.py from django.shortcuts import render from django.shortcuts import get_object_or_404 from .models import Lectie def lectii(req): lectii = Lectie.objects.all().order_by("id") if req.user.is_authenticated: if req.user.profile.lectiiRezolvate == None: lectiiRezolvate=[] else: lectiiRezolvate = req.user.profile.lectiiRezolvate else: lectiiRezolvate=[] context = { 'lectii': lectii, 'lectiiRezolvate': lectiiRezolvate } print(lectiiRezolvate) return render(req, '../templates/pagini/lectii-selector.html', context) def lectie(req, lectie_id): if req.user.is_authenticated: if req.user.profile.lectiiRezolvate == None: req.user.profile.lectiiRezolvate.append(lectie_id) user.profile.save() print(req.user.profile.lectiiRezolvate) else: if lectie_id in req.user.profile.lectiiRezolvate: pass else: req.user.profile.lectiiRezolvate.append(lectie_id) print(req.user.profile.lectiiRezolvate) else: pass lectie2 = get_object_or_404(Lectie, pk=lectie_id) lectiePDF = 'lectii/lectia-{}.pdf'.format(lectie2) context = { 'lectiePDF': lectiePDF, 'lectie2': lectie2, } return render(req, '../templates/pagini/lectii.html', context) urls.py from django.urls import … -

How should i show a HTML field in one template and another field in another template in django?

POST QueryDict not formed correctly with data from multiple forms
I have multiple forms with the same fields: a hidden id input (some forms may not have it), a name field, an email field and a select field. I am performing a request: $.post(url, data, successFunction) and this is how I build data: const data = []; let i = 0; $('.myforms').each(function () { data['entry-' + i++] = $(this).serializeArray(); }); This is how data looks like: { "entry-0": [ { "name": "id", "value": "3" }, { "name": "name", "value": "name1" }, { "name": "email", "value": "" } ], "entry-1": [ { "name": "id", "value": "4" }, { "name": "name", "value": "name2" }, { "name": "email", "value": "" } ], "entry-2": [ { "name": "id", "value": "7" }, { "name": "name", "value": "name3" }, { "name": "email", "value": "name3@email.com" }, { "name": "options", "value": "1" } ], "entry-3": [ { "name": "name", "value": "new" }, { "name": "email", "value": "" }, { "name": "options", "value": "1" }, { "name": "options", "value": "2" } ] } But the QueryDict is not being formed correctly, it's not interpreting the data as I expect: Out[10]: <QueryDict: {u'entry-2': [u'[object Object]', u'[object Object]', u'[object Object]', u'[object Object]'], u'entry-3': [u'[object Object]', u'[object Object]', u'[object Object]', u'[object Object]'], … -

How to pass audio Blob to Django Backend and Server?
I am building a Django WebApp that records multiple speakers, manipulates the files and pushes the result to an IBM Speech Processing tool. I've been stuck at the recording part for two days and would appreciate some help. My goal is to be able to store .wav files in my database, that I can manipulate and send to the IBM tool. In JS, this is how I found how to record the audio. function handlerFunction(stream) { rec = new MediaRecorder(stream); rec.ondataavailable = e => { audioChunks.push(e.data); if (rec.state == "inactive"){ let blob = new Blob(audioChunks,{type:'audio/wav'}); recordedAudio.src = URL.createObjectURL(blob); recordedAudio.controls=true; recordedAudio.autoplay=true; sendData(blob) } } } function sendData(data) { $('.passAudio').val(data); } I can replay it in the audio tag and I'm attempting to pass it as a hidden input. So far, it's telling me it passes an Blob object, but I don't know what to do with that. <audio id=recordedAudio></audio> <input type="hidden" accept="audio/*" id="0" name="audio" class="passAudio"> I'm trying to get it to somehow store in my default storage, but I have no idea if this is even in the correct direction.

Django authenticate() returns none except one case
So i am stuck at a point in my project. I am trying to create users and I have extended User model using the OneToOnefield method as recommended in Documentation to create a user profile. There is no problem in creation of the user as all the details are correctly stored in both the auth_user and appname_userprofile table. The problem I get is when I try to login with any user stored in the auth_user table. Except one case( which i created before creating the userProfile model). So in my auth_user Table the pass for this one case is encoded but for the remaining cases it's plain text. Here is my function handling the view - def login_view(request): if request.method == 'POST': print(request.body) username = request.POST.get('id_username') password = request.POST.get('id_password') print(username, password) try: import pdb; pdb.set_trace() user = authenticate(username=username, password=password) print('This is ',user) if user is not None: login(request,user) else: return redirect('fileupload') print('This is ',user).... some more code Now when i pass the credentials for this one case and try to authenticate. the login works(except my code gets stuck at some later point because this user doesn't have any profile). When i pass the credentials for user created after creating the … -

I am using AJAX to refresh a table in my template by using dataTable. When I get the results from the AJAX call (json) I'm using 'columns' to set every row. In one of the rows, I want to create a Django URL to another view. What I have tried so far doesn't seem to work function refreshData(event_ref) { var table = $('#datatable').dataTable({ 'processing': true, 'serverSide': false, 'responsive': true, 'destroy': true, 'ajax': { 'type': "GET", 'url': "{% url 'events:index' %}", 'dataSrc': "" }, 'columns': [ { "data": "pk", render: function (pk) { return '<input type="checkbox" id="check_' + pk + '" name="check_all">'} }, { "data": "fields.date_time" }, { "data": "pk", render: function (pk) { return "<a href='{% url 'events:event' " + pk + "%}'>Click me</a>" }} ], 'order': [[ 2, "desc" ]], 'columnDefs': [ { 'targets': [0, 8], // column index (start from 0) 'orderable': false, // set orderable false for selected columns }], 'scroller': { loadingIndicator: true } }); } The problem is in the line { "data": "pk", render: function (pk) { return "<a href='{% url 'events:event' " + pk + "%}'>Click me</a>" }} and what I get is this, Reverse for 'event' with arguments '(' + pk + … -
How to fix NoReverseMatch error in Django [duplicate]
This question already has an answer here: What is a NoReverseMatch error, and how do I fix it? 3 answers I'm making a web app to manage students. When creating/ updating students a "NoReverseMatch" error is thrown. I'm new to django but I cannot figure out why it's throwing the error when the exact same pattern name is present in the urls files. The delete redirect does not work either. urls.py: path('Student/', views.StudentListView.as_view(), name='Students'), path('Student/<int:pk>', views.StudentDetailView.as_view(), name='Student-detail'), path('Student/create/', views.StudentCreate.as_view(), name='Student_create'), path('Student/<int:pk>/update/', views.StudentUpdate.as_view(), name='Student_update'), path('Student/<int:pk>/delete/', views.StudentDelete.as_view(), name='Student_delete'), views.py: class StudentDetailView(generic.DetailView): model = Student class StudentListView(generic.ListView): model = Student template_name = 'main/student_list.html' class StudentCreate(CreateView): model = Student fields = '__all__' class StudentUpdate(UpdateView): model = Student fields = ['student_name'] class StudentDelete(DeleteView): model = Student success_url = reverse_lazy('Students') student_form.html: {%block content%} <body> Add new student: <form action="" method="post"> {% csrf_token %} <table> {{ form.as_table }} </table> <input type="submit" value="Submit"> </form> </body> {%endblock%} Instead of redirecting back to the student detail page I get the following error: NoReverseMatch at /Student/1/update/ Reverse for 'Student-detail' not found. 'Student-detail' is not a valid view function or pattern name. Thank you. -
form.as_hidden doesn't pass values to POST
My form has initial values in it. I use form.as_hidden to hide the values and pass those values through a POST request. However, the hidden values are not passing through. Is there a way through this? views.py def car_detail_view(request, id): if request.method == "POST": form = CarForm(request.POST) print(form.is_valid()) if form.is_valid(): car_save = form.instance get_car = Car.objects.get(number_plate=car_save.number_plate) get_car.available = False get_car.save() return redirect('/') else: print(form.errors) else: car = Car.objects.get(id=id) form = CarForm(initial={'brand':car.brand, 'number_plate':car.number_plate, 'price':car.price, 'available':car.available}) args = { 'car':car, 'form':form } return render(request, 'map/confirmation.html', args) confirmation.html <h1>Confirmation of Booking</h1> {% block content %} <p>Brand: {{ car.brand }}</p> <p>Number Plate: {{ car.number_plate }}</p> <p>Price: {{ car.price }}</p> <p> Are you sure you want to book? <p> <form class="" method="post"> {% csrf_token %} {{ form.as_hidden }} <input type="submit" value="Book {{ car.brand }}"> </form> {% endblock %} -
Django: implementing websockets to work with my existing MVT-based app (Channels seems to need me to throw out my entire existing code)
I have an existing Django project in the sports domain with apps that are built on the Model-View-Template structure. Many of the models and views are fairly sophisticated and work well currently. Data from the database (scores etc) is combined with some incoming user inputs through forms (HTTP POST requests) to be displayed on a web page via templates. However, I now need live data to be displayed to users and be automatically refreshed to all the users continuously, either because one of the users entered something new (in the front-end), or because the scores changed during the game (directly enters the back-end). I've done some research on Stack Overflow as well as tutorials on Youtube/ rest of the web and it appears that for me to use Django Channels, I'd have to start from scratch and build everything ground-up, which I'd like to avoid. How do I use the websocket protocol for my Django app easily without having to completely rework everything that I've done so far? -
Messages for users with (user.is_active =False) flag during the login process
I am trying to add message during the log-in process , to a user when he has an account, but deactivated, that he should activate it if he wants to get it. I use LoginView controller, that uses built-in standard form called AuthenticationForm AuthenticationForm has a following method: def confirm_login_allowed(self, user): """ Controls whether the given User may log in. This is a policy setting, independent of end-user authentication. This default behavior is to allow login by active users, and reject login by inactive users. If the given user cannot log in, this method should raise a ``forms.ValidationError``. If the given user may log in, this method should return None. """ if not user.is_active: raise forms.ValidationError( self.error_messages['inactive'], code='inactive', # and list of error messages within this class error_messages = { 'invalid_login': _( "Please enter a correct %(username)s and password. Note that both " "fields may be case-sensitive." ), 'inactive': _("This account is inactive."), } So that technically if not user.is_active – it should show message 'inactive' but in my case for inactivated users with is_active = False DB table it shows the message 'invalid_login' instead. I am trying 100% correct login and password and user is not active but it …
