Unable to run Vue.js 3 along with django code
I'm unable to load Vue.js 3 in my django code. I used Vue from the CDN. Vue import: <script src="https://unpkg.com/vue@next"></script> Html: <div class="row"> <div class="col-md-24"> Here: [[ message ]] </div> </div> JS: console.log(`Vue code inserted`); const app = Vue.createApp({ delimiters: ["[[", "]]"], data() { return { message: "Hello Vue!", }; }, computed: {}, methods: {}, }); app.mount("#todaysappts"); JS console output: You are running a development build of Vue. Make sure to use the production build (*.prod.js) when deploying for production. Vue code inserted Html output: <div class="row"> <div class="col-md-24"> Here: [[ message ]] </div> </div> So, my variable message is not getting interpolated, and the variable name is being printed, with the brackets. How I do it solve this? Apparently vue is loaded, and there are no errors. -

Adding ManyToMany field data between models
I know similar questions have been asked before, but I haven't been able to find a clear answer so any help will be greatly appreciated:) I want to add a predefined list of objects from one model to another using ManyToMany field. However, I am not sure the best practices or how exactly to accomplish this. For example: #models.py class Book(models.Model): BOOKS = ( ('b1','Secret Life of Bees'), ('b2','Pride and Prejudice') ) name = models.CharField(max_length=100, choices=BOOKS) def __str__(self): return self.name class Library(models.Model): librarian = models.OneToOneField(UserProfile, on_delete=models.CASCADE, primary_key=True) books = models.ManyToManyField(Book) #views.py def create_library(request): if request.method == 'POST': form = LibraryCreateForm(request.POST) if form.is_valid(): library = form.save(commit=False) listOfBooks = request.POST.getlist('books') library.save() return redirect('home') else: form = LibraryCreateForm() return render(request, 'create_library.html', {'form':form}) #forms.py class LibraryCreateForm(forms.ModelForm): class Meta: model = Library fields = ['books'] #create_library.html <form method="POST"> {% csrf_token %} <input type="checkbox" value="b1" name="books"> <input type="checkbox" value="b2" name="books"> </form> This isn't working for me, and I don't know how to fix it correctly. To be more specific, I would like to essentially do the equivalent of this in python but with DJango: class Person: def __init__(self, name): self.name = name self.skills = [] class Skill: def __init__(self, name): self.name = name programmingSkillOne = Skill("C++") … -

I am trying to loop through the group of comments and assign a boolean to a new attribute is_liked_by_user.

PasswordResetConfirmView's PASSWORD_RESET_TIMEOUT Message if expired
Good day SO. How to add message if PASSWORD_RESET_TIMEOUT is expired? I am using the django.contrib.auth PasswordResetView to get url link with token for Password Reset. Based on docs, I can add PASSWORD_RESET_TIMEOUT like this: PASSWORD_RESET_TIMEOUT = 10 10 seconds just to test. After 10 seconds pass, I tried to to refresh the page and user can still use the URL to access the PasswordResetConfirmView but can no longer change the password. Even using mismatched password, no response. How should I proceed with this? For reference, this is my URL: path('reset_password/', views.MyPasswordResetView.as_view( template_name="../templates/logauth/reset_password.html", subject_template_name='../templates/logauth/password_reset_subject.txt', email_template_name='../templates/logauth/password_reset_email.html', html_email_template_name='../templates/logauth/password_reset_email.html', from_email=settings.EMAIL_HOST_USER,), name="reset_password"), path('reset_password_sent/', auth_views.PasswordResetDoneView.as_view(template_name="../templates/logauth/reset_password_sent.html"), name="password_reset_done"), path('reset/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(template_name="../templates/logauth/reset_password_2.html"), name="password_reset_confirm"), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(template_name="../templates/logauth/reset_password_complete.html"), name="password_reset_complete"), Form to alter my PasswordResetView: class MyPasswordResetForm(PasswordResetForm): username = forms.CharField(max_length=254) field_order = ['username', 'email'] def __init__(self, *args, **kwargs): super(MyPasswordResetForm, self).__init__(*args, **kwargs) for field in self.fields: self.fields[field].widget.attrs = {'class': 'user-input-form'} View: class MyPasswordResetView(PasswordResetView): form_class = MyPasswordResetForm def form_valid(self, form): username = form.cleaned_data.get('username') email = form.cleaned_data.get('email', '').lower() try: user = get_user_model().objects.get(username=username, email=email) except(get_user_model().DoesNotExist): user = None if user is None: return redirect('password_reset_done') return super().form_valid(form) -
What i'm missing for use Django with Ajax
i want to automatic update a string/field of a simple webpage. The field is the latest date, which i get from this function: def get_latest_date2(): now = datetime.datetime.now(datetime.timezone.utc) - datetime.timedelta(seconds=20) now_string = now.isoformat() return str(now_string[:-14]) + '0Z' So, when i run my django project the time appears on the webpage, but it does not update itself (which is totally normal). So i tried to use ajax to automatic refresh the time, but i'm not getting it from myself. I still don't understand how to make the js script update the time field automatically without a manual update (F5).

Django user profile style auth with Djoser

Lookup to Profile via username in Django
I currently have the setup below, which allows me to extract the profile details for a given pk in the Profile table. You will see that I have extracted the username from the User model in the serializer, to display in the view. I am trying to modify the code to extract the profile for a given username, but changing 'pk' to 'username' and using a lookup field doesn't work. I think this is because I'm trying to do it backwards. Should I therefore create a UserSerializer that accepts the username and then link it to the ProfileSerializer via the 'user' field (this is the one-to-one link to the pk of the User model)? I am not sure how to do that. urls.py urlpatterns = [ path(r'api/profile/<pk>/', views.ProfileView.as_view()), ] serializers.py class ProfileSerializer(serializers.ModelSerializer): username = serializers.CharField(source='user.username', read_only=True) class Meta: model = Profile fields = ('user', 'gender', 'dob', 'username') lookup_field = 'username' views.py class ProfileView(RetrieveAPIView): queryset = Profile.objects.all() serializer_class = ProfileSerializer -

Is Django Rest Framework Authentication Enough?
So I am very new to the topic authentication. I am using Python Django REST Framework to build my REST API and Python Django Channels for a chat. Now I have to build the login, sign in, and so on. Now I just searched, what kind of authentication is good but I have no clue, what I should do. I saw OAuth and JsonWebTokens but it is a big topic. Than I saw Django Rest Framework does have a authentication which I could use. Is it secure? What is OAuth? Can anbody help me? :) I want a sign in system where I enter my email, password, name, and so on and than get a email. Is there a difference if I want to implement this? It also should be secure like Facebook or Instagram EDIT It shouldn't be a complex sign in where I could Sign in Using Facebook or Google. Just a "simple" sign in/authentication system :) Thanks for your efforts -
Django. How to send data to request.POST via Ajax
i am new in JS and Ajax. I have page for administering football game. It has stopwatch and it is why i need to use Ajax for actions (new goal / new penalty / delete action), bcs standard POST processing will redirect to different page or refresh this page, and i will lose stopwatch. Adding a new actions happens in the same page. Request.POST will have info about clicked button (for +goal / +penalty / delete some action), period time and game numbers of players for action. (In examples simplified to the only 'A_goal_time_minute'). In views.py i print type of post: just post or post from ajax. In both variants of html nothing is displayed. If i paste method='post' in form, ajax will be bypassed (as I understand). If i remove onsubmit='doAjaxSubmit() nothing will change. What should i fix to make this work??? views.py class ZipView(TemplateView): template_name = "dev_zip.html" def get(self, request, *args, **kwargs): return render(request, self.template_name) def post(self, request): print("POST") if request.is_ajax(): print('POST is_ajax') print(request.POST) """ Code for new goal or penalty.

Order infinite scroll posts in django
I experience hard time trying to implement infinite scrolling feature :(. The problem is that it orders posts in the wrong way.

Dockerfile for .sqlite3 database

I need to create a docker image of the Database and push it to my repo on AWS ECR. I already have an image of the application there but need a seperate image of the database so the data will persist. Any advice on creating a DockerFile or docker-compose file to do this would be great.
