Django star rating system AJAX and JavaScript
I am trying to implement a star rating system on a Django site. I have found the following, and like the style of the stars here: https://www.w3schools.com/howto/howto_css_star_rating.asp Currently have a limited understanding of JavaScript, AJAX and Django. Does anyone know how to use the stars in the above example combined with AJAX and Django, so you are able to update the database (models) without a page refresh when a user selects a rating? It is also important that users are only able to vote once, i.e. they are not allowed to rate a page twice. For this, there must be an IP check. I am confused about the code and I need help. models.py: class Rating(models.Model): ip = models.CharField(max_length=15) post = models.ForeignKey(Post, related_name='ratings', on_delete=models.CASCADE) score = models.IntegerField(default=0, validators=[ MaxValueValidator(5), MinValueValidator(0), ] ) def __str__(self): return str(self.pk) views.py: def RatingView(request): obj = Rating.objects.filter(score=0).order_by("?").first() context ={ 'object': obj } return render(request, 'blog/post_detail.html', context) # def get_client_ip(self, request): # x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR') # if x_forwarded_for: # ip = x_forwarded_for.split(',')[0] # else: # ip = request.META.get('REMOTE_ADDR') # return ip def RateView(request): if request.method == 'POST': element_id = int(request.POST.get('element_id')) val = request.POST.get('val') print(val) obj = Rating.objects.get(id=element_id) obj.score = val obj.save() return JsonResponse({'success':'true', 'score': val}, safe=False) … -

Django: Foreign Key to User -> Form is not validating because field is required
I'm currently creating a Registration-Page with two parts One part is about the Username and a Passwort. The second part is about choosing the own PC-Configuration After defining everything, the User can register to get to the Main-Page. Therefore I got a Model called "PC_Configuration" with a bunch of Foreign-Keys to the different Database-Models of the Processors/Graphicscards etc.: class PC_Configuration(models.Model): user = models.ForeignKey(User, related_name='user_id', on_delete=models.DO_NOTHING) processor = models.ForeignKey(Processors, related_name='processor_id', on_delete=models.DO_NOTHING) graphicscard = models.ForeignKey(Graphicscard, related_name='graphicscard_id', on_delete=models.DO_NOTHING) os = models.ForeignKey(OS, related_name='os_id', on_delete=models.DO_NOTHING) ram = models.ForeignKey(RAM, related_name='ram_id', on_delete=models.DO_NOTHING) harddrive = models.ForeignKey(Harddrive, related_name='harddrive_id', on_delete=models.DO_NOTHING) Also, there is one ForeignKey to the User to connect the Configuration to the respective User-ID. Inside views.py, I've been creating a DropdownForm for all the Dropdown-Fields which the User shall choose on his own: class DropdownForm(forms.ModelForm): class Meta: model = models.PC_Configuration exclude = [] def __init__(self, *args, **kwargs): super(DropdownForm, self).__init__(*args, **kwargs) self.fields['processors'].queryset = DropdownForm.objects.all() self.fields['processors'].label_from_instance = lambda obj: "%s" % obj.name self.fields['graphicscard'].queryset = DropdownForm.objects.all() self.fields['graphicscard'].label_from_instance = lambda obj: "%s" % obj.name self.fields['os'].queryset = DropdownForm.objects.all() self.fields['os'].label_from_instance = lambda obj: "%s" % obj.name self.fields['ram'].queryset = DropdownForm.objects.all() self.fields['ram'].label_from_instance = lambda obj: "%s" % obj.name self.fields['harddrive'].queryset = DropdownForm.objects.all() self.fields['harddrive'].label_from_instance = lambda obj: "%s" % obj.name But regarding the fact, that the User-ID shall … -

Django/Vue session data for login in development mode
I have a Django/Vue app. I want to login my user to my app but I don't know how it works in the development mode. For production, I build my vue files and access them via Django views so in production, sessions are simply managed by Django. This is OK. But in development mode, I access the FE via a different port. In this case, when I login my user, how Django know that this user is logged in? What should I do to make this happen as in Production without extra configurations? If extra configurations are needed, what are they? -

Django logger does not log below warning level on server
I cannot get the django logger log below WARNING level on my web server. The below configuration logs as intended on localhost dev server, but not on my web server (Nginx, gunicorn). The log file as defined in the file handler is created and logs are written to it, but only logs of level WARNING and above. My goal is to log INFO level logs as well (such as GET requests). I found this discussion (https://stackoverflow.com/questions/65362608/), but it didn't help. I tried configuring root logger for INFO level by adding '': {#same settings as in below django logger} to loggers, but that did not have any effect. I restarted both Nginx and gunicorn. #in settings.py DEBUG = False LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'detailed': { 'format': '{levelname} {asctime} {message}', 'style': '{', }, }, 'filters': { 'require_debug_false': { '()': 'django.utils.log.RequireDebugFalse', } }, 'handlers': { 'file': { 'level': 'INFO', 'class': 'logging.FileHandler', 'filename': '/django.log', 'formatter': 'detailed' }, 'mail': { 'level': 'ERROR', 'class': 'django.utils.log.AdminEmailHandler', 'filters': ['require_debug_false'], } }, 'loggers': { 'django': { 'handlers': ['file', 'mail'], 'level': 'INFO', 'propagate': True, }, }, } Any ideas what might be causing the issue? -

Django & React: Connecting multiple apps from one template

How are all serializer errors returned in DRF at once?
I'm testing for multiple validation errors to be raised in(UserRegistrationSerializer). Yet DRF only returns the first error that is raised: {'username': [ErrorDetail(string='Choose a different username', code='invalid')]} I'm expecting: {'username': [ErrorDetail(string='Choose a different username', code='invalid')], 'password2': [ErrorDetail(string='Password confirmation failed', code='invalid')] How can multiple errors be accounted for once a serializer is validated as in the documentation example? https://www.django-rest-framework.org/api-guide/serializers/#validation class TestRegisterationSerializer__002(TestCase): '''Verify that the registeration process fails with respect to selecting an unavailable username and password confirmation''' @classmethod def setUpTestData(cls): User.objects.create_user(username="Python") cls.data = { 'username': "Python", 'password': "#secret#", 'password2': "Secret" } cls.error_messages = [ "Choose a different username", "Password confirmation failed" ] cls.serializer = UserRegisterationSerializer(data=cls.data) def test_user_registeration_invalid_confirmation(self): self.serializer.is_valid() print(self.serializer.errors) import re from django.contrib.auth.models import User from rest_framework import serializers class UsernameSerializer(serializers.ModelSerializer): username = serializers.SlugField(min_length=4, max_length=12) def validate_username(self, value): try: self.Meta.model.objects.get(username__iexact=value) except self.Meta.model.DoesNotExist: return value raise serializers.ValidationError("Choose a different username") class Meta: fields = ['username', ] model = User class LoginSerializer(UsernameSerializer): password = serializers.RegexField( r"[0-9A-Za-z]+", min_length=5, max_length=8 ) def validate(self, data): username, password = [ input.lower() for input in [data['username'], data['password']] ] if all(password[i] == password[i + 1] for i in range(len(password) - 1)) or username == password: raise serializers.ValidationError({ 'password': "Invalid password" }) return data class Meta: fields = ['username', 'password', ] …
