Remove HTML tags in Django messages
Basically I have a view with Django where I add some messages like this: from django.contrib import messages def myView(request): #some stuff messages.error(request, "My message here") return render(request, "myApp/myTemplate.html", context = data) And then I print them in the template like this: {% if messages %} {% for message in messages %} <div>{{ message }}</div> {% endfor %} {% endif %} But the problem is that the messages framework is adding HTML tags to the message and when the message is printed, the <ul> and <li> tags are added. So after the template is rendered it looks like this: <div><ul class="errorlist"><li>My message here</li></ul></div> I would like to know if there is a way to avoid the message getting these html tags added. Also, I would need it outside of the template too, so in the unit tests I can do something similar to: messages = list(response.context["messages"]) self.assertEquals(len(messages), 1) self.assertEquals(str(messages[0]), 'My message here') Is there any way to achieve this? Currently using Python3 and Django 4 Note that I would like to completely avoid the framework to add the tags, so I do not need to use striptags filter. -
Django Can't access URL Pk from FormView Class
I am putting together a simple medical-related project that includes allowing user to order lab tests on a patient. From the patient screen they select Order Tests. The UrlPattern, which includes the Patient pk, brings up the OrderTestsView which is a FormView. The kwargs in this view have no pk even though it is in the Url. I use a FormView because I need to access the list of tests selected in the Forms MultipleModelsChoice. But I need the patient information before the Order form is selected because I have to display who the patient is at the top of the order screen. Normally I would use get_context_data to do all of this, but the kwargs are blank. Not sure why FormView ignores the pk parameter, but how do I fix this? urls.py path('order-tests/<pk>/', OrderTestsView.as_view(), name='order-tests'), forms.py class TestOrderForm(forms.Form): choice = forms.ModelMultipleChoiceField(Universal_Test_File.objects.all().order_by('test_name'), to_field_name="service_id") view.py class OrderTestsView(FormView): model = Universal_Test_File form_class = TestOrderForm success_url = '/list_tests/' template_name = "lab/order_tests.html" patient = get_object_or_404(Patient, pk) ***## CANNOT ACCESS PK*** def form_valid(self, form): choice = form.cleaned_data.get("choice") if choice: for test in choice: print(test.service_id, test.test_name) -

getting AttributeError 'str' object has no attribute 'data' when makinh request to Django-based Server from Flutter application
Hello fellow developers! I am trying to make a request to my Django-based server. lets first look at the endpoints that are causing trouble url.py path("getBookings/<str:Role>/<str:id>/", views.getBookings), path("archiveBooking/<str:Role>/<str:id>/", views.archiveBooking), these endpoints work fine when I make a request to them via localhost i.e. when I run the server with python manage.py runserver they also work fine when I try to make a request via my heroku-deployed application.

SQL - How do I create a linkage table?
I'm building the following data model in Django / SQL Table 1 (Entity) - things that can do things Entity ID: Enum: (Person, or Business) Table 2 (Person) Entity ID: Person ID: Firstname Lastname Table 3 (Ltd Co.) Entity ID: Ltd Co. ID: Company Name Company No. I'm trying to link a Person, who has a Limited Co., with an Agent (who is also a Person) that also has a Limited Co. So 4 different entitites, two of which are type Person, and two of which are type Limited Co. Do I need another Linkage Table? E.g. Profile Person Profile Ltd Co Agent Person Agent Ltd Co Entity 1: Type Person Entity 3: Type Business Entity 2: Type Person Entity 4: Type Business Q. How do I create this Linkage Table in a Django Model / or SQL? Q. Is a Linkage Table the right approach? -
Django form buttons
I have an order form that should display product sizes as buttons, but the buttons do not register to be selected unless a user clicks exactly on the letter for the size ('S', 'M', etc.) in the exact center of the button. Clicking the space between the letter and the border of the button marks it as selected, but when you click Add to cart, it deselects itself. class OrderForm(forms.Form): def __init__(self, instance, *args, **kwargs): super(OrderForm, self).__init__(*args, **kwargs) self.instance = instance self.fields['size'] = forms.ModelChoiceField( queryset=self.instance.sizes.all(), widget=forms.RadioSelect()) The HTML is as follows: {% for choice in order_form.size %} <button type="button" class="size-btn">{{ choice }}</button> {% endfor %} Sizes is a simple model: class Size(models.Model): size = models.CharField(max_length=10) def __str__(self): return self.size This way the rendered HTML is a mess: <button type="button" class="size-btn"> <label for="id_size_0"> <input type="radio" name="size" value="2" id="id_size_0" required>S </label> </button> How do I fix the buttons so that they get selected even if clicked outside of the very center, in the size letter? Thanks. -

How to solve Django send_mail schedule problem?
I am using Pythonanywhere (PA) and like to use the PA's task scheduler to send scheduled emails. I made a ne file called: weeklyemailmm.py. The email settings in the setting.py works with other emailing stuff on my site. What am I doing wrong? I ty to use the code below: from django.core.mail import send_mail import datetime from django.conf import settings settings.configure(settings, DEBUG=True) today = datetime.date.today() weekday = today.weekday() subject = 'New weekly email' message = 'Hi there!' if (weekday == 2): try: send_mail( 'Subject here', 'Here is the message.', 'from@gmail.com', ['to@gmail.com'], fail_silently=False, ) print('It is Wednesday, email sent') except: print('It is not Wednesday') else: print('Email does not sent') On this way I always get It is not Wednesday. If I delete the try-except part and outdent it says: RecursionError: maximum recursion depth exceeded while calling a Python object If I delete the settings.configure(settings, DEBUG=True) that could be possibly wrong it say: django.core.exceptions.ImproperlyConfigured: Requested setting EMAIL_BACKEND, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. -

Error H12 "Request timeout" on heroku for django application
I am getting the H12 "Request timeout" error when I am working with large data in a CSV file and when the data in the CSV file is less the app is working fine. The logs that I am getting is : 2022-02-27T06:05:20.963369+00:00 heroku[router]: at=error code=H12 desc="Request timeout" method=POST path="/" host=youtube-channel-list.herokuapp.com request_id=36c5fe9b-21c5-40de-8804-a75786dfd32e fwd="27.97.65.233" dyno=web.1 connect=0ms service=30699ms status=503 bytes=0 protocol=https I updated my Procfile also as: web: gunicorn channelList.wsgi --timeout 120 --keep-alive 5 --log-level debug --log-file - But still, the same error is coming. What exactly do I need to do? If you need more information, I am ready to provide it.
