DRF's token authentication with Angular
I'm using django for backend and Angular for frontend and DRF for making api calls. I'm making a user login system but currently the user gets logged out on refreshing the page. For preventing this i'm using rest_framework.authtoken.models.Token for generating token's for each user and I'm returning this token in my api call but I've no idea how to use this token in Angular to keep the user logged in on refreshing the page?

Django MultiValueField with MultiWidget
My Django 3.1 app keeps a user identity card info like this: XA12345678 (XA is a series of a user identity card and 12345678 - its 8-digit number). But in a form, I want users to select the series from the dropdown list and enter the number in the text field. So, it seems appropriate to use a custom form field and widget based on MultiValueField and MultiWidget. Unfortunately, Django official documentation isn't much help. So far, I have found only a few up to date pieces of information from the other sources. What my present code looks like: #Custom field class SICField(forms.MultiValueField): widget = SICWidget def __init__(self, reg_ex, *, is_stripped=True, **kwargs): fields = ( forms.ChoiceField(), forms.RegexField(reg_ex, strip=is_stripped) ) super().__init__(fields, **kwargs) def compress(self, data_list): return ''.join(data_list) #Custom widget class SICWidget(forms.MultiWidget): template_name = 'widgets/sic_widget.html' def __init__(self, attrs=None, series_attrs=None, number_attrs=None, options=()): widgets = [ forms.Select(choices=options, attrs=attrs if series_attrs is None else series_attrs), forms.TextInput(attrs=attrs if number_attrs is None else number_attrs) ] super().__init__(widgets) def decompress(self, value): if value: return [value[:2], value[2:]] return [None, None] #MyForm class MainForm(forms.Form): SERIES_CHOICES = [('ХА', 'ХА')] sic = SICField('^\\d{8}$', label='User Identity Card', widget=SICWidget(number_attrs={'placeholder': _('8-digit number of your card')}, options=SERIES_CHOICES)) The main problem is there isn't any value for the … -

Update the 'CHOICE' in the post method
I have a Model with Choices applied to one of the attributes: class Booking(models.Model): BOOKING_STATUS_CHOICES = [ ('RESERVED', 'Reserved'), ('COMPLETE', 'Complete'), ] status = models.CharField( max_length=10, null=False, blank=False, choices=BOOKING_STATUS_CHOICES, default='RESERVED' ) other_attributes = models.OtherFields() etc My ModelForm does not include this attribute as a form field. Instead, I want to update the value in the post method of the form. I am loosely following a walkthrough project where the form is saved but not committed, and then any other values that werent part of the form are added to the form instance before committing the save. What I have is below: def post(self, request): form = self.form_class(request.POST) if form.is_valid(): booking = form.save(commit=False) booking.status = "COMPLETE" booking.save() However checking the admin panel afterwards shows this value has not been applied. I am sure this is really simple to do but I can't find how to do it. Any help would be appreciated -

Seperation of dialogues based on specific users in Django
I am trying to implement direct messaging into my blog app using Django. Pretty much like Instagram direct but without using anything fancy like socket programming and Django channels. In other words, I don’t want online and instant chatting. I have made a simple Message in my message app in my project. It works properly and users can send messages to each other. The problem is that when I want to bundle each dialogue (two specific user) I cannot do it. I mean, I get all messages pretty fine but I cannot find any way to separate messages between different users. I want user to be able to click on the person that he or she wants and after that in a separate url his or her messages will be shown. I know that I have not included any code and my problem is so abstract. But to be honest my problem is the methodology of implementing this not the Django code itself. -

get chained queryset ajax django
I want to get a queryset through ajax request and use it as I can do with django queryset in template. I have the following codes: # view.py def ajax_get_allocates_by_date(request): """ ajax 요청 함수 """ today = timezone.localdate() date = request.GET.get('kw', today.strftime('%Y-%m-%d')) date=parse_date(date) d=Date.objects.get(date=date) allocate_list = Allocate.objects.filter(date=d) data = { 'date': serializers.serialize( 'json', [d] ), 'allocate_list': serializers.serialize( 'json', allocate_list ) } return JsonResponse(data) template <form method="get"> ... <input type="text" id="refer-date" name="refer-date" class="frm_input2 frm_date"> ... </form> ... <script> $('#refer-date').datepicker({ onSelect: function(dateText, inst) { let date = $(this).val() console.log(date) $.ajax({ url: "{% url 'allocate:get-allocates-by-date' %}", data: { 'kw': date }, success: function(data) { let date = JSON.parse(data.date) let queryset = JSON.parse(data.allocate_list) console.log(date) console.log(queryset) } }) } }) </script> If the value of #refer-date is changed, I get ajax response and it is logged in console. However, my Allocate model has some other ForeignKey relationship, which I also want to display in the template. For now it seems I can only render some id if the field is ForeignKey. The best would be use django for loop as ajax response, but I'm not sure how I can achieve that. Any suggestion would be highly appreciated. Thank you. -

Django ValueError: Field 'id' expected a number but got 'myuser'
I need to use my usernames to panel/profile/<username> address. So what I did in models is: class Customer(models.Model): user = models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE) first_name = models.CharField(max_length=30, null=True) last_name = models.CharField(max_length=30, null=True) def __str__(self): return str(self.user) And in urls.py I have these paths: urlpatterns = [ path('panel', views.home, name='panel'), path('panel/register', views.registerPage, name='register'), path('panel/login', views.loginPage, name='login'), path('panel/logout', views.logoutPage, name='logout'), path('dashboard', views.userProfile, name='dashboard'), path('dashboard/settings/edit-profile', views.userSettings, name='settings'), path('panel/profile/<str:username>', views.profile, name='profile'), ] and in this way there is no problem: >>> customer=Customer.objects.get(user_id=118) >>> customer.user.username 'myuser' But in views.py I need to grab username as a part of URL like that: @login_required(login_url='login') @allowed_users(allowed_roles=['admins']) def profile(request, username): customer = Customer.objects.get(user=username) print(type(customer), customer) But I have this error: ValueError at /panel/profile/myuser Field 'id' expected a number but got 'myuser'. -
Callback Endpoints in Django
I have a scenario were a view function sends a post request to an external webserver which sends the callback response to a endpoint in my application. My question is how do I identify the session flow, that is how do I know that the callback response on the endpoint is for the user who triggered the view function initially. -
Django view not executing
I'm implementing an excel export function in one of my django apps, but when I click the link that is supposed to execute the view, nothing happens, and the server is not running the view at all. This is the button that is supposed to run that view: <li class="nav-item mt-sm-2 mt-lg-0"> <a href="{% url 'catalog:export_all_csv' %}" class="btn btn-success btn-sm" download="OrdenesProximas" tabindex="0" data-toggle="popover" data-trigger="focus" title="¡Archivo descargado!" data-content="El archivo ha sido descargado exitosamente."> <i class="uil-file"></i> Exportar catálogo a Excel </a> </li> My urls.py for the app: from django.urls import path from . import views app_name = 'catalog' urlpatterns = [ path('catalog/list/', views.ProductList.as_view(), name='product_list_table'), path('catalog/add/', views.create_product, name='add_product'), path('catalog/category/add/', views.CategoryCreate.as_view(), name='add_category'), path('catalog/<slug:category_slug>/', views.product_list, name='product_list_by_category'), path('catalog/<slug>/list/', views.CategoryProductList.as_view(), name='category_product_list_table'), path('catalog/', views.product_list, name='product_list'), path('catalog/<int:id>/<slug:slug>/', views.product_detail, name='product_detail'), path('catalog/<int:id>/<slug:slug>/edit/', views.edit, name='product_edit'), path('catalog/export_csv/', views.export_csv, name='export_all_csv'), ] The view: @login_required def export_csv(request): import pdb; pdb.set_trace() categories = Category.objects.filter(company=request.user.profile.company) queryset = Product.objects.filter(category__in=categories) response = HttpResponse(content_type='text/csv') response['Content-Disposition'] = f'filename=productos.csv' writer = csv.writer(response) writer.writerow(['Id de Producto', 'Categoría', 'Nombre del producto', 'SKU', 'Código de barras', 'Marca', 'Proveedor', 'Color', 'Medidas', 'Descripción', 'Observaciones', 'Precio 1', 'Precio 2', 'Precio 3', 'Impuesto (%)', 'Costo de fabricación']) for item in queryset: writer.writerow([item.id, item.category.name, item.name, item.sku, item.barcode, item.brand, item.provider, item.color, item.measures, item.description, item.observations, item.price_1, item.price_2, item.price_3, item.tax, item.fabrication_cost]) return response …
