Debugging stops automatically in my django app in vscode
Im learning django currently and when I started to debug the application using debugging and run section in vs code, it starts and is going off within 2 seconds. I have done all the things followed by the tutor. He's on mac, he created a launch.json and set Django debugger for web apps. I did the same. I have installed the python intellisense and Don jayamanne python package extensions too. Then I started the run in debugger, debugger started and gone in 2 seconds. And Im working in a virtual env, will there be anything I need to configure in .vscode/settings.json path. I didn't get anything in settings.json file after setting virtual env python path in the pallette. What should I do to run debugging? Clear explanation about why debugging isn't running and why I didn't get a pythonPath in settings.json file. What to do to run debugging? -
How to update all the objects in a set one by one?
I have a simple Django project with some minor HTMX here and there, where I can perform a search and it returns results on the page without refreshing. There is a delete button on each result, which when pressed, deletes that element from the database and the view is immediately updated with the remaining results with no refresh. I have added a universal delete button up top, which when clicked, loops through the database queryset and deletes all the elements and returns the view. As a result, the view has all the results one moment and the next it's suddenly empty. I want to change the implementation such that when this delete all button is pressed, it deletes every element one by one while updating the view after each delete. How can I go about this? -

To add a button that autofills a random password on the password field which I created using py-script
I created a form in html which returns to a function in views.py in django framework. I wanted to add a button which autofills the password field with a random password.

But the button seems to be returning to the views.py instead of autofilling. <body bgcolor="white"> <py-script> import random password = '' def mypass(): length = random.randint(8,16) list1=[] for i in range(0,length): list1.append(chr(random.randint(32,126))) password = ''.join(list1) pyscript.write('python', password) </py-script> <script> function myfun(){ var a = document.getElementById("password1").value; var b = document.getElementById("password2").value; if(a!=b){ document.getElementById("messages").innerHTML="Passwords do not match"; return false; } } </script> <script> function myfunction(){ var password = PyScript.interpreter.globals.get('password'); document.getElementById("password1").value = password; } </script> <form onsubmit="return myfun();" action="register" method="post" > {% csrf_token %} <p> <label for="user_name">User Name</label> <input type="text" name="user_name" id="user_name" placeholder="Antman56." autocomplete="on" > </p> <p> <label for="f_name">First Name</label> <input type="text" name="f_name" id="f_name" placeholder="Dave" autocomplete="on" > </p> <p> <label for="l_name">Last Name</label> <input type="text" name="l_name" id="l_name" placeholder="Lee" autocomplete="on" value="keyan" > </p> <p> <label for="email">Email ID</label> <input type="email" name="email" id="email" placeholder="davelee@gmail.com" autocomplete="on" > </p> <p> <label for="password1">Password</label> <input type="password" name="password1" id="password1" placeholder="123$aBc" > </p> <p> <label for="password2">Confirm Password</label> <input type="password" name="password2" id="password2" placeholder="123$aBc" ><span id="messages" style="color:red"></span> </p> <div id="python"></div> <button onclick="mypass()">create random password</button> <button onclick="myfunction()">fill the … -
Want to make it obvious that I can reverse reference by related_name in Django
My Environment IDE: VSCode Extensions of VSCode Python Pylance Ruff Python Type Hint isort djLint Django Black Formatter What's my problem I am working on a quiz submission site with Django. I created a models.py file for a quiz and a user as follows: class User(AbstractUser): pass class Quiz(models.model): title = models.CharField(max_length=50) content = models.TextField() user = models.ForeignKey( User, on_delete=models.CASCADE, related_name="posted_quizzes" ) correct_answer = models.CharField(max_length=50) The above code adds the property posted_quizzes to the user class due to Django's related_name reverse querying functionality. This is a very useful function, but it is not obvious just by looking at the User class, even though it is a property of the User class. I often define new methods, forgetting that they are accessible via related_name. Is there any way that properties added via related_name can be seen directly from the User class? What I tried I tried adding directly as an unimplemented property as follows: import abc class User(AbstractUser): @abc.abstractproperty def posted_quizzes(self): """ defined by related_name of Quiz model posts the user posted """ pass class Quiz(models.model): title = models.CharField(max_length=50) content = models.TextField() user = models.ForeignKey( User, on_delete=models.CASCADE, related_name="posted_quizzes" ) correct_answer = models.CharField(max_length=50) This method is good in that it does not … -

Setting similarity threshold for trigram_similar Django PostgreSQL lookups?
We're using Django's trigram similarity __trigram_similar lookup and it works nicely, except we want to adjust the similarity threshold and don't know how. Queries are currently filtered like so: class MarkerViewSet(viewsets.ReadOnlyModelViewSet): queryset = tablename.objects.all() def filter_queryset(self, queryset): queryset = super().filter_queryset(queryset) queryset = queryset.filter(colname__trigram_similar= search_value) We thought we could add something like similarity__gt=0.1 to the args for filter() like this answer does, but it throws the error "django.core.exceptions.FieldError: Cannot resolve keyword 'similarity_gt' into field". They are using the .filter() function in a different way we don't understand which might be the problem. What's the argument and how can we supply it? Seems we might be able to adjust it manually in PostgreSQL with set_limit (previously SET pg_trgm.similarity_threshold), but we'd prefer to set this in Django. -

In my views.py def search(request): query = request.GET.get('q', '') if query: sp = SpotipyConnection(client_id=sp_client_id, client_secret=sp_client_secret) #context = {'search': sp.searchbar(query)} context = {'search': sp.songSearch(query)} return render(request,'main/search.html',context=context) return render(request,'main/search.html',{}) def search_results(request): if request.method == 'POST': #TODO how do i get the context of what was clicked songName = None songArtist = None context = openAISearch(artist=songArtist,song=songName) return render(request,'main/search_results.html',context=context) In my search.html: {% block title %} Search {% endblock %} {% block content %} <script> function redirectToHome(songName, songArtist) { <!-- TODO how do I call my search_results function then return the redirect --> } </script> <form method="GET" action="{% url 'search' %}"> <input type="text" name="q" id="search-input"> <button type="submit">Search</button> </form> </form> {% if search %} {% for result in search %} <p onclick="redirectToHome({{ result.name }},{{ result.artists.0.name }})"> {{result.name}} by {{ result.artists.0.name }} <img src="{{ result.album.images.0.url }}" alt="{{result.name}} image" style="width: 200px; height: 200px;"> </p> {% endfor %} {% endif %} {% endblock %}``` -
How to call variable processed in forloop function (views) in django template?
I am trying to refer a variable p in my django template after some logic was applied to it. Since it seems templates are only a place for making a page look nice, there must be a way to assign a value to a variable in a forloop and refer it into the template. views def function(request): q = Model.objects.all p = None for model in q : for in_model in ... if something: p = 1 return render(request,"template.html", {'q ':q , 'p':p}) template {%for model in q %} {% for in_model in ... %} {% if p == 1 %} P=1 {%else%} {%endif%} {%endfor%} {%endfor%} Following an example like this, how do I can I test if p=1? It seems whatever I try p=None because this is where the variable is first mentioned in the view. I tried to keep my example as generic as possible, I am hoping it wont affect the clarity of my question. Happy to provide more code if necessary. -
How can i only send and verify Tokens only in Djoser Django and not a pair of Token and Uid
I am trying to make a mobile app, and I only want to use Djoser to send the token once a user registers on the app. The most significant issue I have is that Djoser sends both a UID and a token, which I don't want. I only want it to send the Token a user can enter into the verify email field on the mobile app. How can I do that using Djoser in Django? DJOSER = { 'LOGIN_FIELD': 'email', 'USER_CREATE_PASSWORD_RETYPE': True, 'USERNAME_CHANGED_EMAIL_CONFIRMATION': True, 'PASSWORD_CHANGED_EMAIL_CONFIRMATION': True, 'SEND_CONFIRMATION_EMAIL': True, 'SET_USERNAME_RETYPE': True, 'SET_PASSWORD_RETYPE': True, 'PASSWORD_RESET_CONFIRM_URL': 'password/reset/confirm/{uid}/{token}', 'USERNAME_RESET_CONFIRM_URL': 'email/reset/confirm/{uid}/{token}', 'ACTIVATION_URL': 'activate/{uid}/{token}', 'SEND_ACTIVATION_EMAIL': True, 'SERIALIZERS': { 'user_create': 'users.serializers.UserCreateSerializer', 'user': 'users.serializers.UserCreateSerializer', 'user_delete': 'djoser.serializers.UserDeleteSerializer', } }
