Cannot import from or debug models.py
I've created 5 classes in a models.py inside my app city. I successfully created a db in postgres by importing each class inside the console accordingly. Next, I created a jobs.py script inside the city app so I can automatically scrape data using bs4 and populate/update a db accordingly. The problem occurs when I try to import each class from models.py at the top of my jobs.py script: from city.models import restaurants, barbers, apartments, bars, parks Generates: 'Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.' Any idea why I'm unable to import the classes from models.py into the jobs.py script? I also created a python package utils inside my project. Inside utils is a name_directory.py script that I'm also unable to import into my jobs.py script. Also, I just tried debugging my models.py file and it generated the same error! -
How to deploy tailwind flowbite and django application on Heroku server
I'm a tailwind CSS fanatic and a Django developer. On my own system, I was able to successfully install flowbite using django. On my local system, I ran correctly, however when I launched to a Heroku server, nothing happened. On the internet, I was unable to locate a useful tutorial on how to do it. Would you kindly direct me to a blog post or instructional video that describes how to host a Django and Flowbite application on a development server like Heroku? -
Django / How to refer to a specific news in views so that it is possible to leave a comment on the site through the form?
When submitting a form on the site, the "news_id" value is not pulled into the database (into the table with comments). Accordingly, it is not clear to which news a comment was left so that it could be published later. There are Russian symbols in the code, but they do not affect the essence of the problem in any way. models: class News(models.Model): title = models.CharField(max_length=255, verbose_name="Заголовок") slug = models.CharField(max_length=255, unique=True, db_index=True, verbose_name="URL") content = models.TextField(verbose_name="Содержимое") photo = models.ImageField(upload_to="news/%Y/%m/%d/", verbose_name="Изображение") video = models.URLField(max_length=255, blank=True, null=True, verbose_name="Ссылка на видео") time_update = models.DateTimeField(auto_now=True, verbose_name="Время изменения") category = models.ForeignKey("NewsCategories", on_delete=models.PROTECT, verbose_name="Категория") def __str__(self): return self.title def get_absolute_url(self): return reverse("show_news", kwargs={"news_slug": self.slug}) class Meta: verbose_name = "Новость" verbose_name_plural = "Новости" ordering = ["-time_update"] class Comments(models.Model): news = models.ForeignKey( News, on_delete=models.CASCADE, related_name='comments_news', verbose_name="Новость" ) user = models.ForeignKey(User, on_delete=models.CASCADE, verbose_name="Автор комментария") time_create = models.DateTimeField(auto_now_add=True, verbose_name="Время создания") content = models.TextField(verbose_name="Содержимое") status = models.BooleanField(verbose_name="Публикация комментария", default=False) def __str__(self): return self.content class Meta: verbose_name = "Комментарий" verbose_name_plural = "Комментарии" ordering = ["-time_create"] forms: class CommentForm(forms.ModelForm): content = forms.CharField( label='Добавить комментарий', widget=forms.Textarea(attrs={'rows': '4', 'class': 'form-control'})) class Meta: model = Comments fields = ['content'] utils: class DataMixin: def get_user_context(self, **kwargs): context = kwargs cats = NewsCategories.objects.annotate(Count('news')) context["cats"] = cats if "category_selected" … -

Styling comments in Django
I found this tutorial on Django and Making a Hacker News Clone. Figure it'd be a good starting point as it's an pretty good break down with the Django and some concepts like comment parenting https://www.askpython.com/django/hacker-news-clone-django I thought cool and got through it, started learning more on Django Got my own search implemented into this too. However the comments on this were not great. So I wanted to improve things on it to make commenting prettier than the big colored blocks. However I've been stuck trying to make comment styling more Hacker News or Reddit style. I went searching and found https://css-tricks.com/styling-comment-threads/ though it it still didn't work the way I was figuring and wanted to have a more simplistic style though I'm running into a few issues. My idea would be to having it |Parent comment | Child Comment | Grandchild Comment | Child Comment2 |Parent Comment2 etc My commentpost.html comments section I modified {% for comment in comments %} {% if comment.identifier %} <div class="comment-thread"> <div class="replies"> <div class="comment-heading"> <div class="comment-vote"></div> <div class="comment-info"> <a href="#" class="comment-author"><a href = "{% url 'user_info' comment.creator.username %}">Comment by: {{comment.creator.username}}</a> | <strong>Thread Level: {{comment.identifier}}</strong></p> </div> </div> <div class="comment-body"> <p> <strong> {{ comment.content}} </strong> … -

Cannot resolve telethon AuthKeyDuplicatedError
Using Telethon to access a Telegram account and accidentally ran my dev server simultaneously with our production server the other day and now getting this error when trying to create a Telethon connection: telethon.errors.rpcerrorlist.AuthKeyDuplicatedError: An auth key with the same ID was already generated I've switched out the auth key and we deleted all the active sessions in our Telegram account, but to no avail. This is a script in a Django application running in docker on AWS EC2. Could there be a session file lurking somewhere I can't find? I'm using a redis cache, which I've cleared a couple times with no change to the error message either...although I didn't really think it was going to help. Any more ideas would be appreciated. note: I tried the solution steps listed here in this question it did not resolve the problem. -

Are Django user registration form fields limited to 'username', 'password1', 'password2', 'email', 'first_name', and 'last_name'?
I started a tutorial (seems like ages ago now) in which I built a user registration form with just 'username', 'email', password1', and 'password2' fields. Then a profile form was created on a separate page -- but I didn't like the way CreateProfile page/form looked. So I wanted to be able to put the fields in the CreateProfile form into the user registration form. I still have not found an answer about how to do that. -

Guild ID Exception
With the django-allauth module, I am wanting to throw an exception if the user is not in a particular guild. What I am hoping to do is pass in a ACCOUNT_GUILD_REQUIRED = True, or within the provider settings the option for GuilDID. I can then catch that in user.model.manager to check if they are in the guild or not. -

How do I add a csrf token to a json fetch in js?
Every time I try to run the code, I get an error that a CSRF token is missing. I have tried adding the token in the html and then adding an event listener for the form but that did not work as I still got the error and the console linked it to the line where I fetched a url. Attempt: (the {{ form }} is a django form which contains a textarea) <div id="add-form"> <form action="" id="form-add"> {% csrf_token %} <h2>New Post</h2> {{ form }} <input type="submit" value="Post" /> </form> </div> // Javascript document.querySelector('#form-add').onsubmit = submit // submit is the function with the fetch command So instead I used babel to add the form into the html (this was not to fix the problem). I have tried to manually add a CSRF token to the react form but I still got the same error: Forbidden (CSRF token missing.): /post. I also tried to add it using a JQuery function I found here (django documentation) but it did not work probably because every time I added the CSRF token in the form I still got the error. So how do I add a csrf token to a fetch command in … -

Whole Javascript Not Working if 1 Array has Length of 0
Hi I am creating a bar chart, and having an issue with the JS in the chart. The JS is supposed to find the % of the total that each rating represents. For instance, A1 = 100 and total equals 1000, so a1 width should be 10%. The JS code works perfectly, except for when the array has no values in it, for instance when A2 has a length of 0. When this happens, it also makes all the values after it not work, even if they have arrays greater than a length of 0. I was wondering if anyone had an idea of what was going wrong thanks. <div class="statistics"> <h6>Rating Distribution</h6> <div class="bar-graph bar-graph-horizontal bar-graph-one"> <div class="bar-one"> <span class="rating">A1</span> <div class="bar" id="a1-rating" data-percentage=""></div> </div> <div class="bar-two"> <span class="rating">A2</span> <div class="bar" id="a2-rating" data-percentage=""></div> </div> <div class="bar-three"> <span class="rating">A3</span> <div class="bar" id="a3-rating" data-percentage=""></div> </div> <div class="bar-four"> <span class="rating">B1</span> <div class="bar" id="b1-rating" data-percentage=""></div> </div> </div> </div> <div class="hidden-rating-distribution-data"> {% for loans in a1_companies %} <div class="security-value-a1" hidden>{{loans.market_value}}</div> {% endfor %} {% for loans in a2_companies %} <div class="security-value-a2" hidden>{{loans.market_value}}</div> {% endfor %} {% for loans in a3_companies %} <div class="security-value-a3" hidden>{{loans.market_value}}</div> {% endfor %} {% for loans in b1_companies %} <div … -

The issue I have is that all users may see the admin messages. i thought i views from .models import Support, Comment from .forms import SupportForm, CommentForm @login_required def support_details(request, id): support = Support.objects.get(id=id) recent_support = Support.objects.all().order_by('-created_at') comments = Comment.objects.all() if request.method == 'POST': comment_form = CommentForm(request.POST) if comment_form.is_valid(): comment = comment_form.save(commit=False) comment.user = request.user comment.save() comment_form = CommentForm() messages.success(request, 'comment posted successfully') else: comment_form = CommentForm() context = { 'support': support, 'recent_support': recent_support, 'comments': comments, 'comment_form': comment_form } return render(request, 'support-detail.html', context) models from users.models import User from django.db import models class Support(models.Model): SERVICE_CHOICES = ( ("Crypto", "Crypto"), ("Transaction", "Transaction"), ("Others", "Others"), ) support_id = models.CharField(max_length=10, null=True, blank=True) user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True) subject = models.CharField(max_length=30, null=True, blank=True) email = models.EmailField(null=True) related_service = models.CharField( max_length=100, choices=SERVICE_CHOICES, null=True) message = models.TextField(max_length=1000, null=True) is_close = models.BooleanField(default=False) created_at = models.DateTimeField(auto_now=True, null=True) def __str__(self): return self.subject class Comment(models.Model): comment = models.TextField(max_length=1000, null=True) user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='user', null=True) support = models.ForeignKey(User, on_delete=models.CASCADE, related_name = 'comment', null=True, blank=True) created_at = models.DateTimeField(auto_now=True, null=True) def __str__(self): return self.comment template {% extends 'base2.html' %} {% load static %} {% load crispy_forms_tags %} {% load widget_tweaks %} {% block … -
I keep getting : Reverse for 'delete_entry' with arguments '('',)' not found. 1 pattern(s) tried: ['deleteentry/(?P<input_id>[^/]+)/\\Z']

Django Rest Framework, creating a one-to-many field relationship between users and another model
I am trying to create a simple model which holds a number as the primary key (week number) and then a list of users. Thus the model should be something like this, { id: 10, users: [ user1, user2, ... ] } I am pretty sure I should do this with a one-to-many field. Thus I created the following model, class Schema(models.Model): week = models.PositiveIntegerField(primary_key=True, unique=True, validators=[MinValueValidator(1), MaxValueValidator(53)], ) users = models.ForeignKey(MyUser, related_name="users", null=True, blank=True, on_delete=models.SET_NULL) class Meta: ordering = ('week',) What I want to happen is that if you do a POST request with an id and a list of users, then it simply creates the model. However if the id already exists, then it should simply clear the users, and add the newly given users instead. This is where I am stuck, I have tried the following (keeping comments in the code), class SchemaSerializer(serializers.ModelSerializer): # users = serializers.PrimaryKeyRelatedField(many = True, queryset = MyUser.objects.all()) # user_set = UserSerializer(many = True) class Meta: model = Schema fields = ('week', 'users') # def create(self, validated_data): # # users_data = validated_data.pop('users') # schema = Schema.objects.create(**validated_data) # # answer, created = Schema.objects.update_or_create( # # week=validated_data.get('week', 1), # # defaults={'users', validated_data.get('users', [])} # # … -
I can't place text and video in same grid in django with css
I have application which includes 3 videos(eventually it will include more). I have created a model in models.py and passed courses to template with context in my view. I want my title to be in border below the video but it makes some weird pose. I left some space under image for title. html <div class="next"> {% for course in courses %} {{ course.title }} <video src="/media/{{ course.videofile }}" controls=controls type="video" class="video">{{ course.title }}</video> {% endfor %} </div> css .next{ margin-top: 8em; display: grid; grid-template-columns: .1fr .1fr .1fr; gap: 1em; } .video{ max-width: 15em; border: 1px solid black; padding-bottom: 2em; } If I place for loop in another div it works better but titles are above videos. html <div class="next"> {% for course in courses %} <div class="div"> {{ course.title }} <video src="/media/{{ course.videofile }}" controls=controls type="video" class="video">{{ course.title }}</video> </div> {% endfor %} </div> (css is the same)
