Django Migration Error With MSSQL Database With Schemas
I just start to create the settings for Django backend (All in Python). I use MS SQL and I run my django in Linux to connect to MSSQL. After setting the databases specifications, I run into the following error. Given that my database has more than schemas, I assume i have to tell django which schema to use in the database, but i fail to find the right place. Any ideas ? My settings: DATABASES = { 'default': { 'ENGINE': 'sql_server.pyodbc', 'NAME': 'MyDB', 'HOST': '********', 'PASSWORD': '**************', 'AUTOCOMMIT': True, 'USER': 'root', 'OPTIONS': { 'driver': 'ODBC Driver 17 for SQL Server', }, }, }``` Error: ```django.db.migrations.exceptions.MigrationSchemaMissing: Unable to create the django_migrations table (('42000', "[42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Hello there. It looks like you're trying to create an object without specifying a schema name. Please create in a named schema, eg schemaname.tablename\r\n\t (50000) (SQLExecDirectW)"))``` -
Javascript file incorrect? Django
I am writing a Django website. I am trying to use a JavaScript file to move a mobile nav bar into the page when clicking on the burger icon. I have successfully loaded a JavaScript file from the static folder. (I checked with the alert function.) However, once I write more code in the JavaScript file, the JavaScript file doesn't work and I don't get the alert "Hello, javascript file loaded" upon refreshing the website page. Is my javascript incorrect? Is the format incorrect for use in Django? Any help would be much appreciated, thanks for reading. App.js alert("Hello, javascript file loaded"); const navSlide = () => { const burger = document.querySelector('.burger'); const nav = document.querySelector('.nav-links'); burger.addEventListener('click', () = > { nav.classList.toggle('nav-active'); }); } navSlide(); Base.html {% load static %} <html> <head> <title>Pep Genie</title> <link rel="stylesheet" type="text/css" href="{% static 'genie/style.css' %}"> </head> <body> {% block content %}{% endblock %} <script src="{% static 'genie/app.js' type="text/javascript" %}"></script> </body> </html> Index.html {% extends 'genie/base.html' %} {% block content %} <nav> <div class="logo"> <h4>The Logo</h4> </div> <ul class="nav-links"> <li> <a href="#">Home</a> </li> <li> <a href="#">About</a> </li> <li> <a href="#">Work</a> </li> <li> <a href="#">Our Projects</a> </li> </ul> <div class="burger"> <div class="line1"></div> <div class="line2"></div> <div class="line3"></div> … -

NestedSimpleRouter without using lookup in router
I am using drf-nested-router something like the following in my url.py router = SimpleRouter() profile_router = routers.NestedSimpleRouter(router, r'profile', lookup='user') profile_router.register(r'comments', UserCommentViewSet, basename='profile-comments') The viewset is class UserCommentViewSet(CommentViewSet): def get_queryset(self): return Comment.objects.filter(owner=self.request.user) So the URL is something like, mydomain.com/profile/{profile_id}/comments/ it gives me right results. But the following URL is also giving me right results, mydomain.com/profile/{anything}/comments/ because I am using the session user info to filter the data. Is it possible to make the URL like mydomain.com/profile/comments/ Thanks in Advance. -
Looking for suggestions... Which language/framework should I use for my project?
For a project in my mind -and to learn while doing- I have to choose a language / framework and start learning. My goal is to quickly create a mvp that looks good and has basic functions. I have good command of basic programming concepts. I know html and css, but I'm not very dominant, but I can reveal what I want by looking at the documentation. I know basic sql queries. I don't have any experience in js or php. I have been building many websites with wordpress for a long time, but of course it is not useful for this project. Hosting part is not an issue for me, I can host the project on my home server or on the AWS. There will be simple crud operations in the project; Create product / service / user profiles Listing and filtering within these profiles Matching between profiles Send requests to matching services (all or selected) (can be via email) As a result of my rapid research, django one came out, but I am not sure if the learning process will take a long time. I learned php in college years ago, I am not thinking whether to try … -

Django ManyToManyField Persistence Fails
I have a simple Django 3.1.0 app I need to create in order to assign Tasks with Tags (or assign tags into tasks). My Model class Task(models.Model): user = models.CharField(max_length=33) time = models.DateTimeField(auto_now_add=True) task = models.CharField(max_length=500) tags = models.ForeignKey('Tag', on_delete=models.SET_NULL, null=True) class Tag(models.Model): tag = models.CharField(max_length=30, default="No Tag") members = models.ManyToManyField('Task') class Meta: verbose_name = "tag" verbose_name_plural = "tags" My Form class TaskForm(ModelForm): class Meta: model = Task fields = ['user', 'task', 'tags'] template_name = 'tasks.html' tags = ModelMultipleChoiceField( queryset=Tag.objects.values().all(), widget=CheckboxSelectMultiple() ) My View def main(request): model = Task.objects.values().all() form = TaskForm() con = {'context': list(model), 'form': form} if request.method == 'POST': form = TaskForm(request.POST) if form.is_valid(): obj = form.save(commit=False) form.save_m2m() return redirect('/') else: form = TaskForm() return render(request, "tasks.html", con) The migrations are successfull, and with the above code, the view shows a checkbox list with the fetched tags, but the problem is that when I hit Submit on the form, the values are not saved/written on the database but the page reloads successfully. However, if I turn the following: obj = form.save(commit=False) form.save_m2m() into form.save(commit=True) #form.save_m2m() the values are written only from the fields 'user', 'task' - without the 'tags' It's also funny that what fetches back on … -

Django ORM QuerySet with Aggregation Max function
I tried to Convert the SQL command: SELECT fname,lname FROM customer WHERE id > (SELECT max(id) FROM customer WHERE state = 'TX'); to an ORM (Django) QuerySet. At my first try I use: Customer.objects.filter(id__gt=Customer.objects.filter(state='TX').values('id')).values('fname','lname') But it gave me the wrong output (I compare with the raw sql query) So, I learn more and achieve the following: Customer.objects.filter(id__gt=Customer.objects.filter(state='TX').values('id').aggregate(Max('id'))['id__max']).values('fname','lname') I'm a junior so think to address SO for the following two questions: I have two questions: What happens in the first QuerySet, that output the wrong results ? (It doesnt crash) The QuerySet with the correct result, is long and complex in comparison to the SQL raw query. Is it the correct QuerySet ? Can I achieve the same result with a more simple QuerySet ? Thanks ! -

What would I miss, if I don't use any authentication in django and login the user using django query filter with a manually hashed password
I have seen the default user authentication and custom user uathentication in django, I would like to know what would I be missing if I just login a user by using a normal query like, ____.objects.get(password = ______, email = ______) and just hash the password stored in the model column.And store the login details in session and clear them on logout. Would it ruin the security altogether or is it something else I wouldn't get which is found in the normal django authentication? -

Booking system for fitness / gym company - Where to store booking data, what django-models should I use?
I have to make (high school project) booking/reservation system for fitness / gymnastics service company. Users (clients) can have: tickets - for 1 hour (on 1 day) - "single ticket" subscription - 1 hour a day for one, two or three months. Overall, I have some idea how to make this application, but only need help with choosing best / optimal Django model for storing booking / reservation information. Assuming that there can be maximum N ( N ~ 15) persons in fitness club at the same time, I can sell limited number of tickets and subscriptions for particular day/hour. Where (what Django model suits best) should I store booking / reservation informations, For example: User No. 0001 is taking fitness at Monday, 25 January, 2021, 5 pm to 6 pm (single ticket) User No. 0002 is taking fitness at Friday, 30 January, 2021, 11 am to 12 am (single ticket) ..... User No. 0055 is taking fitness every weekday from 3 pm to 4 pm for whole January and February (subscription) ..... etc. What Django model do You recommend in my case? -
Django and Heroku - Migration is applied before its dependency
I'm having trouble getting my Django web app from a local server to Heroku. To try and troubleshoot I created a new app from scratch and managed to push that through to Heroku with no problems. The issue comes when I add class User(AbstractUser): pass to models.py, then run makemigrations and migrate. The error is: django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency mainapp.0001_initial on database 'default'. One thing that might be causing it is that I'm using sqlite3 on localhost then Postgres on the Heroku server (although I'm not advanced enough to know if that is actually the problem!) Also my gitignore file contains: /venv __pycache__ db.sqlite3 mainapp/static/ Should it also include the migrations folder? Any help or ideas would be appreciated!

Jinja .css template logic
I am wiring my framework to wagtail. It is a custom module css framework called reely.io that is made for Hubspot. It has jinja variables for breakpoints, colors, etc. one of the variables is a multiplier for padding and margin settings.
