Django - ManyToMany relationship not unique
So the case is : I have a Course model with a manytomany relationship to a student model . The course also have a one to many relationship with a Module model, so a course have many modules but each module belongs to one course . On my Module i specified a boolean field named completed to be able to calculate how much modules of that course did the student complete . The main problem is : When a module is completed by a student, it's marked as completed forever. In other words, when another user enrolls in the same course , he will find the completetion state of the modules as left by the other user . I want each modules to be initialized when a student enrolls in a course , but also want to them to be saved just for that student without saving the changes globally, it's like making an initialized copy of the course whenever a new user enrolls in it, and save his records on this copy not on the actual Course model in the database . Thanks and here's the code : class Student(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True, blank=True) full_name = models.CharField(max_length=200, … -
Python Django - Are periods in a string processed correctly when retrieved from an api?
In Python to include a period in a string you need to add the escape key \ in front of the period . so "example\.com" appears as "example.com" say I'm programming in Django and a Python SDK returns a specific url such as "example.com/abcdef" I assume I don't have to worry about adding a \. to "example.com/abcdef" so that it is "example\.com/abcdef". Can you explain the reason why I don't need to add the \. in this case. -

Cannot create new Table with FK in Django
I'm trying to add a new table to my mysql database. The table consists of only two items, each of which is a foreignKey (further down). However, when migrating the changes to the DB I receive an error message (further down) I know that the problem is in the HS_Countries foreignKey as I tested it and it is possible to migrate the table when that key is not present. I have other tables where I have a HS_Countries foreignKey. Thats why I'm quite confused by the problem. The structure of HS_Countries is further down and also the structure of the other foreignKey. I am not sure what I have to change to get the migration to work. New table: class User_Accumulated_Countries(models.Model): iso_code = models.ForeignKey( 'HS_Countries', on_delete=models.CASCADE, related_name='iso_code') product = models.ForeignKey( 'User_Product', on_delete=models.CASCADE, related_name='product') console log: Operations to perform: Apply all migrations: main Running migrations: Applying main.0113_user_accumulated_countries...Traceback (most recent call last): File "/Users/5knnbdwm/Python_env/lib/python3.8/site-packages/django/db/backends/utils.py", line 86, in _execute return self.cursor.execute(sql, params) File "/Users/5knnbdwm/Python_env/lib/python3.8/site-packages/django/db/backends/mysql/base.py", line 74, in execute return self.cursor.execute(query, args) File "/Users/5knnbdwm/Python_env/lib/python3.8/site-packages/MySQLdb/cursors.py", line 209, in execute res = self._query(query) File "/Users/5knnbdwm/Python_env/lib/python3.8/site-packages/MySQLdb/cursors.py", line 315, in _query db.query(q) File "/Users/5knnbdwm/Python_env/lib/python3.8/site-packages/MySQLdb/connections.py", line 239, in query _mysql.connection.query(self, query) MySQLdb._exceptions.OperationalError: (3780, "Referencing column 'iso_code_id' and referenced column … -
How do I make bootstrap card go next to each other when they are generated by django?
I made a blog in django but there is a problem.

Sum numeric values from different tables in one query
In SQL, I can sum two counts like SELECT ( (SELECT count(*) FROM a WHERE val=42) + (SELECT count(*) FROM b WHERE val=42) ) How do I perform this query with the Django ORM? The closest I got is a.objects.filter(val=42).order_by().values_list('id', flat=True).union( b.objects.filter(val=42).order_by().values_list('id', flat=True) ).count() This works fine if the returned count is small, but seems bad if there's a lot of rows that the database must hold in memory just to count them. -

Django + openvpn authentication
I'm currently working on a django project (academic). This project consists of a ecommerce website, developed in Django. This site sells vpn subscriptions. The VPN server is ubuntu 18.04 with Openvpn server. My initial idea is to create one db (mysql) where users will be able to authenticate to the django site and also to the vpn server. So no problem to create the django authentication for the users but I'm having difficulties in finding a way to authenticate the users to the VPN server. This would be possible if I did something stupid like leaving the password in plaintext :-) but off course I will not do that. So the VPN server is up and running with mysql db, the django site not completelly yet, but I have the authentication app up and running. Django uses pbkdf2_sha256 as hashing algorithm by default and the server, for the moment, is using plaintext. I'm wondering if anyone knows a library I could use in order to make it possible for the VPN server to be able to authenticate the users, or if I should change the defaut hashing algorithm in Django to match a hashing algorithm of an existing library like … -

Django: how to run a function that creates an object (using information from view) when user clicks a button
I have a Word model where users can create their own words (using Django's CreateView). I also have a Dictionary view that shows the WordList page (using django-filter's FilterView) for one specific (special) user, like this: from .filters import WordFilter from django_filters.views import FilterView class Dictionary(FilterView): model = Word template_name = 'vocab/dictionary.html' context_object_name = 'dict_list' paginate_by = 15 filterset_class = WordFilter strict = False def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['filter'] = WordFilter(self.request.GET, queryset=self.get_queryset()) return context def get_queryset(self): qs = self.model.objects.filter(user__username__iexact='special_user') return qs def get_object(self): queryset = qs pk = self.kwargs.get('pk') if pk is None: raise AttributeError('pk expected in url') return get_object_or_404(queryset, pk=pk) What I want to do now is to give every user the option of adding any word he/she wants from this list - without having to leave the page. In other words, when a user clicks a button a certain function must be run (without the need to first go to a new page). One way I thought of doing this is to write a create view with dynamic initial values given what word the user clicked on. But the problem is that in the Dictionary view I do not have access to the object; for that … -

I would like to know what I am doing wrong? how can I fix the view? there is also (in green) a gap in the field how can I remove the gap?. picture: JS $("#id_start_time").datepicker({}); my head of the page: <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title></title> <!-- Data Tables--> <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.20/css/jquery.dataTables.css"> <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/rowreorder/1.2.6/css/rowReorder.dataTables.min.css"> <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/responsive/2.2.3/css/responsive.dataTables.min.css"> <script type="text/javascript" charset="utf8" src="https://code.jquery.com/jquery-3.3.1.js"></script> <script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/1.10.20/js/jquery.dataTables.min.js"></script> <script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/rowreorder/1.2.6/js/dataTables.rowReorder.min.js"></script> <script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/responsive/2.2.3/js/dataTables.responsive.min.js"></script> <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/selectize.js/0.12.6/js/standalone/selectize.min.js" integrity="sha256-+C0A5Ilqmu4QcSPxrlGpaZxJ04VjsRjKu+G82kl5UJk=" crossorigin="anonymous"></script> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/selectize.js/0.12.6/css/selectize.bootstrap3.min.css" integrity="sha256-ze/OEYGcFbPRmvCnrSeKbRTtjG4vGLHXgOqsyLFTRjg=" crossorigin="anonymous"/> -
Adding placeholder to UserCreationForm in Django
I want to add placeholders to the UserCreationForm in Django. I'm a bit confused, bc when I search for this topic I only find stuff like this with complicated answers, where people suggest to change the /lib/site-packages/django/contrib/auth/forms.py . Isn't it an awful idea to change the code of Django itself? Couldn't you just create a custom form like this, when you add placeholders to the authenticationForm: from django import forms from django.contrib.auth.forms import AuthenticationForm from django.forms.widgets import PasswordInput, TextInput class CustomAuthForm(AuthenticationForm): username = forms.CharField(widget=TextInput(attrs={'class':'validate','placeholder': 'Email'})) password = forms.CharField(widget=PasswordInput(attrs={'placeholder':'Password'})) Thx for your help and stay healthy!
