Render the same form in template with initial data
I'a stuck with the following problem. I an Employer model, an Employee model, an HourCode model and a ReportModel. I will begin with the outcome i want to see, maybe then its clear what iam asking. Every employee has a employer and every employer has hourCodes for time registration. For Example: John is working at xerox, he worked 10 normal hours and 5 extra hours. In this case the hourcode are "normal hours" and " extra hours ". In my template i want to render a sort of table view so that de hours can be filled by the employer. So in this case he had to fill in 10 hours on "normal hours" and 5 hours on "extra hours" at John. But, the employer has ofcourse multiple employees, so he has to fill in several lines with the worked hours and extra hours per employee. Employeename. Normal hours. Extra hours John. 10. 5 Eva. 3. 5 SaveButton After savebutton pressed the forms (in this case 2, each for every employee) has to be saved to the ReportModel. The Reportmodel has some fields (ForeignKey fields to employer, employee and hourcodes. Long story, my question how can i render the view … -

How to set an unspecified value to Meta class (How to create a template table class) django_tables2
I have more than 30 tables, so I don`t want to write the same code for all of them. Even its copypaste. All my tables should look like this one: class MyTable(tables.Table): edit_link = tables.columns.Column(viewname='edit_table_field', kwargs={'table_name': 'MyModel', 'pk': A('pk')}, text='edit) ... class Meta: model = MyModel ... I want to make a tamplate from this class which will take the name of the model (MyModel) as an argument and create the same tablestables for each of them in one class. I don't know how to pass a value from a class to a metaclass. Also, maybe someone know any frameworks for python that implements the mapping and CRUD methods for my tables like it`s in Vaadin (Java)? -

I've already installed Django, and yet when I try to create a project, the following message appears... can't open file 'U:\django-admin': [Errno 2] No such file or directory I've seen on other questions asked, that it would require one to have a virtual environment; however, on the tutorials I've been following, it doesn't install an environment. -

Using jQuery DateTimePicker in Django Admin form get error - Enter a list of values

Define CSS variables from Django Models
I'm trying to create an app where the user would be able to customize the design.

Custom auth system django
I have an app with ability to unite users by groups. So you can auth in it using built-in django auth system and use app in single mode, but also login in group (that adds additional functionality). Need to auth user in group-mode using group data, then write that group in user's foreign key for group. So I have user model like this: class CustomUser(AbstractUser): ... note_group = models.ForeignKey(NoteGroup, on_delete=models.DO_NOTHING, null=True, blank=True) ... And group model: class NoteGroup(models.Model): id = models.BigAutoField(primary_key=True) group_name = models.CharField(max_length=25) password = models.CharField(max_length=25) For now I have this view: def group_notes_view(request): if request.method == 'POST': form = GroupSignInForm(request.POST) if form.is_valid(): group = NoteGroup.objects.get(group_name=form.instance.group_name) if group: if group.password == form.instance.password: user = request.user user.note_group = group user.save() ... else: form = GroupSignInForm() ... Form looks lie this by now class GroupSignInForm(ModelForm): class Meta: model = NoteGroup fields = ('group_name', 'password') It's working but I believe there is much better way to do it. -
Django Stripe account link return_url and refresh_url redirects causes user to be logged out of web application platform
I'm integrating stripe into my Django web application platform. When sellers onboard with Stripe Connect, an Account is created for them, and an AccountLink is created with a specified return_url and refresh_url that Stripe uses to redirect back to my web application. However, when the sellers are redirected back to my web application they are no longer logged into the web application. Is there a better solution than forcing the user to log back in? The following are some code snippets: views.py def stripe_on_boarding(request): if request.method == "GET": stripe_sk = settings.STRIPE_SECRET_KEY stripe.api_key = stripe_sk user = request.user account = None print("I'm logged in as and am onboarding stripe [" + user.first_name + "]") if user.stripe_account is None: account = stripe.Account.create(type='express') user.stripe_account = account.id user.save() print("Saved User Object!") else: account = stripe.Account.retrieve(user.stripe_account) if account is not None and not account.details_submitted: account_links = stripe.AccountLink.create( account=account.id, refresh_url='http://098c818fbf8a.ngrok.io/marketplace/stripe_on_boarding_refresh', return_url='http://098c818fbf8a.ngrok.io/marketplace/seller_return', type='account_onboarding', ) return redirect(account_links.url) return render(request, 'become_seller_part_1.html', {'msg' : "You've already registered with stripe.", 'is_registered' : True}) # TODO: render a page if this view was triggered by a method other than GET. Could this be happening because I'm using ngrok to redirect to my localhost? -

Django Custom Manager + DRF + UWSGI setup : Incorrectly applied queryset filters
We are using Django 3.1.5, python 3.8, and Django Rest Framework ModelViewSet Architecture for our application. Our application is a multi-tenant system where all the tenants of our application are using the same database and schema, we have added a foreign key to tenant to make the models tenant aware (if applicable). For our system, we call tenants Clients. To filter all the queries by the client by default, we have done the below steps: Used local thread storage to store client id for each request. This is set at a middleware before each request and gets cleared in the end. Created a custom manager to override objects working. Here, we filter queries by client_id stored in the local thread.So, everytime, some_model_query = SomeModel.objects.all() is done, then some_model_query is filtered by client stored. Our view sets are written in the below format: class SomeModelViewSet(CustomModelViewSet): queryset = SomeModel.objects.all() serializer_class = SomeModelSerializer filterset_class = SomeModelFilter We are using uwsgi to run our application on servers. Now, the problem with uwsgi: The first time, when a process is run, then, all the view sets are initialized and hence their querysets. During initialization, querysets are set with the current client_id. So, it becomes: SomeModel.objects.filter(client_id=1).all() … -
Python Django LineBot Error 54 'Connection reset by peer'
I'm trying to crete linebot through python Django, I want to send some messages and let it scrape the website. Since there is form on the website, I use post request to send the form. Although I scrape the data successfully, there is error message showed in the python. It seems linebot occupy post method in Django and I send another post request again. I'm not sure my understanding is correct. I can't find any solution about this. Could someone teach me how to fix it?
