Register button won't disappear when user logs in(django, html, css, bootstrap)
Why is this code showing the register button regardless of whether or not a user is logged in? (this is for Django with bootstrap) ''' {% if user.is_authenticated %} <li class="nav-item"> <span class="navbar-text"}">Study hard, {{ user.username }}.</span> </li> <li class="nav-item"> <a class="nav-link" href="{% url 'users:logout' %}">Log out</a> </li> {% else %} <li class="nav-item"> <a class="nav-link" href="{% url 'users:register' %}">Register</a> </li> <li class="nav-item"> <a class="nav-link" href="{% url 'users:login' %}">Log in</a></li>''' -
Django displays source code instead of web page
I am new to django. Any help will be appreciated. It displays source code instead of web page. To be specific the base page (base.html). What I want is to use the data from patient details and doctors detail as they are from different groups. I think that the problem is when i pass my dictionary. Views.py def booking(request): if not request.user.is_active: messages.success( request, ("In order to book an appointment you must login first")) return redirect('login') doctor_details = Doctor.objects.all() f = {'doctor_details': doctor_details} g = request.user.groups.all()[0].name if g == 'Patient': patient_details = Patient.objects.all().filter(EmailAddress=request.user) d = {'patient_details': patient_details} return render(request, 'booking.html', f, d) Html {% extends 'base.html' %} {% block content %} {% load static %} <div class="loginContainer"> <div class="img"> <img src="{% static 'image/booking.svg' %}"> </div> <div class="login-content"> {% for d in patient_details %} <form method="POST" id="signupForm"> {% for f in doctors_details %} {% csrf_token %} <h2 class="title">Booking form</h2> <div class="input-div one"> <div class="i"> <ion-icon name="person-circle"></ion-icon> </div> <div class="div"> <h5>Patient ID: PID - {{d.id}}</h5> </div> </div> <div class="input-div one"> <div class="i"> <ion-icon name="person"></ion-icon> </div> <div class="div"> <h5>Name: {{d.FirstName}} {{d.LastName}}</h5> </div> </div> <div class="input-div one"> <div class="i"> <ion-icon name="business"></ion-icon> </div> <div class="div"> <h5>Department</h5> <input type="text" class="input" name="age" required> </div> </div> <div class="input-div … -
Save multiple objects in Django DRF ViewSet create
I have a model in Django which stores some basic information. class Inventory(models.Model): created_at = models.DateTimeField(auto_now_add=True) added_by = models.ForeignKey(User, on_delete=models.SET("anonymous"), name = models.CharField(max_length=100, unique=True) nickname = models.CharField(max_length=100, blank=True, null=True) manufacturer = models.ForeignKey(InventoryManufacturer, on_delete=models.PROTECT) comment = models.TextField(max_length=500, blank=True, null=True) link = models.URLField(max_length=100, blank=True, null=True) class Meta: unique_together = ('manufacturer', 'manufacturer_part_no') I have another table which stores images for this model: class InventoryImages(models.Model): created_at = models.DateTimeField(auto_now_add=True) added_by = models.ForeignKey(User, on_delete=models.SET("anonymous"), blank=True, null=True) file = ImageField(blank=True, default='', upload_to='inventory/images/%Y/%m/') primary = models.BooleanField(default=False) order = models.IntegerField(blank=True, null=True) item = models.ForeignKey(Inventory, on_delete=models.CASCADE, blank=True, null=True, related_name='images') What is the right way to handle a scenario where a user can fill out a form (where you can set the Inventory model fields) and also upload multiple images. What I did now that the user can upload images everytime on this form, the image gets uploaded but the item Foreign Key stays null. When the user submits the form, the ForeignKey is set for each uploaded image. The scenario when a image gets discarded (no form submission) is handled. This is what I did now: def create(self, request, *args, **kwargs): # Create Inventory item serializer = CreateInventoryItemSerializer(data=request.data) serializer.is_valid(raise_exception=True) serializer.save(added_by=self.request.user, updated_by=self.request.user) # Save properties inventory_id = serializer.data['id'] # Add id … -
Django - convert datetime string to timezone aware datetime object
So I have a a list of dates and times as a string "2022-01-23 21:30” that I need to import into my Django Application My Django server UTC, however the strings are intended to be UTC+2. So if I import it directly, Django would assume it’s UTC and then the timestamp would saved as 2022-01-23 21:30 (UTC), where in reality it should be converted to 2022-01-23 19:30 (UTC). Is there a specific way I should format it before saving the object in a Django DateTimeField so it will become timezone aware? Thanks in advance. -
formset function update view does not save the forms because the id is missing
I have a view to update 6 of my formset only that the click of the send button gives me the error that the id of each form is missing ... how do you fix it?

CSRF cookie is not set in Django after API call
I have a small Django web app that allows you to log in with a platform using their API. The user is able to log in, but the callback from the log in returns this error: Forbidden (CSRF cookie not set.): /account/platforms/apicallback/ on my server output. I believe that the callback does route to the correct url in my web app, but when it gets to the view associated with it, the CSRF cookie error arises. My request code is below: params = { "app_name": "My App", "scope": scope, "user_id": request.user.id, "return_url": redirect_uri, "callback_url": "https://www.myapp.co.uk/account/platforms/apicallback", "state": {"platform":"api"} } query_string = urlencode(params) url = "%s%s?%s" % (auth_url, query_string) return redirect(url) Here is the urls.py file that contains the callback url: urlpatterns = [ path(r'apicallback/', views.apicallback, name='apicallback'), ] Here is the views.py file with the view for the callback url: @login_required def apicallback(request): consumer_key = request.GET.get('consumer_key') consumer_secret = request.GET.get('consumer_secret') I have got two APIs already working with my web app that both use OAuth2.0, and I haven't come into this issue before. Any ideas on how to fix it without disabling CSRF cookies. Thank you -
Can not use POST method with Django 4 Rest Framework
I'm having an issue with a new django 4 app not processing or not allowing POST method. I used to bypass this in Django version 3 by adding a trailing slash "/" to the end of url in Postman API Tester like http://127.0.0.1:8000/api/didipay/ instead of http://127.0.0.1:8000/api/didipay . But now in my Django 4 API I completed the url with the slash but POST method is still not processing the data. It gives me a "500 internal server error" and I don't understand where it is coming from. The GET method is rather giving an empty array which is normal because I've not inserted any data yet in the database. I'm using venv, Django 4 Rest framework, serializer, viewSet and these is my models and API urls configurations: //Serialize.py from rest_framework.decorators import permission_classes from didipay_app.models import Didipay_app from rest_framework import viewsets, permissions from .serializers import Didipay_appSerializer class Didipay_appViewSet(viewsets.ModelViewSet): queryset = Didipay_app.objects.all() permission_classes = [ permissions.AllowAny ] serializer_class = Didipay_appSerializer // Project folder's urls.py from django.contrib import admin from django.urls import path, include urlpatterns = [ path('', include('didipay_app.urls')), ] // App folder's urls.py from rest_framework import routers, urlpatterns from .api import Didipay_appViewSet router = routers.DefaultRouter() router.register('api/didipay', Didipay_appViewSet, 'didipay') urlpatterns = router.urls The … -
Python Paramiko "exec_command" does not execute - Django
I am facing an issue with the Python Paramiko library in my Django Application This is a function I have written to create an SFTP connection: def createSFTPConnection(request,temp_pwd): ssh=paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) user = User.objects.get(username=request.user) ssh.connect(hostname=temp_host,username=user.username,password=temp_pwd,port=22) sftp_client=ssh.open_sftp() return ssh,user,sftp_client This just returns me the variable for ssh, the username, and sftp_client Then I execute a command on the remote server using this code - ssh,user,sftp_client=createSFTPConnection(request,temp_pwd) # passes the password on that server for the user for creating the connection cmd_to_execute="(cd "+temporary_path+"; sh temp.sh"+" "+var1+" "+var2+")" # executing a shell script by passing it 2 variables stdin, stdout, stderr = ssh.exec_command(cmd_to_execute) # actual call print("stderr: ", stderr.readlines()) print("pwd: ", stdout.readlines()) Now, this code works fine and executes the script "temp.sh" on the remote server, but it takes a lot of time as I am returning stdin, stdout and stderr and printing them on the console But, since I don't want that I removed the readlines() calls from there making my code look like this - cmd_to_execute="(cd "+temporary_path+"; sh temp.sh"+" "+var1+" "+var2+")" stdin, stdout, stderr = ssh.exec_command(cmd_to_execute) # actual call But for some reason, this code just doesn't execute on the remote server after removing the readlines() calls Thus, making me think that exec_command … -

Django Models Multiple Field Saving
I'm trying to create an object in my Order model. My js return a list of multiple values for Model database however I can not save multiple values that I received from ajax as a list. I see it's an array in js and a list in django but it's not happening. I've tried ManyToManyField instead of ForeignKey for my Order model model field, but that did not work too.

Django not logging all errors on production
My Django app is locally properly logging and emailing errors. However, on production, I'm only getting 'Invalid HTTP_HOST header' errors in both the log file and my inbox.

It throws an error saying that refresh field is required. my code: export const refreshToken = (token) => { let object = { refresh: token, }; return (dispatch) => { api .post(TOKEN_REFRESH_ENDPOINT, object) .then((response) => { dispatch(refreshSuccess(response.data)); }) .catch((error) => { dispatch(refreshFail(error.message)); }); }; }; React.useEffect(() => { let refreshToken = Cookies.get(TOKEN_REFRESH_NAME); let timer = setTimeout( () => dispatch(action.account.refreshToken(refreshToken)), 2 * 1000 ); return () => { clearTimeout(timer); }; }, [dispatch]); What am I doing wrong? -
Django form with formset between three models
I have three models: Experiment, Label and LabelMappings while LabelMappings is connecting Devices with Labels. I want to create ExperimentForm but don't know how to add Label field to it using inline formset. I am using ClassBasedViews but couldn't figure out how to save Labels and build this relationship in backend class Experiment(models.Model): name = models.CharField(max_length=255) comment = models.TextField(blank=True, null=True) class Label(models.Model): name = models.CharField(max_length=255) comment = models.CharField(max_length=255, blank=True, null=True) class LabelMappings(models.Model): experiment = models.OneToOneField(Device, models.DO_NOTHING) label = models.ForeignKey(Location, models.DO_NOTHING) I thought about somethinglike LabelMappingFormSet = inlineformset_factory(Experiment, LabelMapping, form=LabelMappingForm, extra=1 ) LabelFormSet = inlineformset_factory(LabelMappingForm, Label, form=LabelForm, extra=1 ) but i didn't work out. -

Problem: If the user close tab or browser, item status stays as "31.Verificando usuario" and another user cannot review this invoice. **How can I capture …
