Captcha wouldn't show up in my html file in Django
I was trying to implement Captcha for my contact form. I followed the instructions, Installed Django-simple-captcha. Pillow was already installed. Made migrations, added the path to urls.py and created the appropriate class in forms.py. I put captcha in the INSTALLED APPS sections in settings. My urls.py is - urlpatterns = [ path('', include('calc.urls')), path('admin/', admin.site.urls), path(r'captcha/', include('captcha.urls')), ] My views.py is - def contact_sub(request): if(request.method == 'POST'): form = CapForm(request.POST) if(form.is_valid()): x = 3 else: form = CapForm() else: form = CapForm(request.GET) if(form.is_valid()): x = 3 else: form = CapForm() txtarea = request.GET['sum_inq'] fname = request.GET['fname'] cont_list = "First Name: " + fname lname = request.GET['lname'] cont_list = cont_list + '\n\nLast Name: ' + lname email_id = request.GET['email_id'] cont_list = cont_list + '\n\nEmail Id: ' + email_id are_you = request.GET['are_you'] cont_list = cont_list + '\n\nWhich of the following most accurately describes your organization?: ' + are_you if(are_you == "Other"): specify1 = request.GET['ay_specify'] cont_list = cont_list + '\n\nSpecify: ' + specify1 cont_list = cont_list + '\n\nSummary of Inquiry:\n' + txtarea try: validate_email(email_id) send_mail('Contact Form', cont_list, settings.EMAIL_HOST_USER, ['emailaddress'], fail_silently=False) #context = {'message': "Sent"} request.session['message'] = "Sent" return HttpResponseRedirect(reverse("contact_us")) #return render(request, "contact.html", context) except ValidationError: #context = {'message': "Not Send"} request.session['message'] = "Not … -
Error When Debugging Django project with ImageFields in Visual Studio Code
I spent so long solving this problem I wanted to post it in case it helps others. I have a django project in Visual Studio Code and I configured a virtual environment for the project. I would run the project in the Integrated Terminal using manage.py runserver after activating my virtual environment and that worked. I created a debug configuration with the default launch.json for django projects. Running the debugger, I got this error: (fields.E210) Cannot use ImageField because Pillow is not installed.HINT: Get Pillow at https://pypi.org/project/Pillow/ or run command "python -m pip install Pillow". Pillow was installed in the virtual environment as well as my global python installation. -

Django Unable to update model based on link click
I'm trying to update the model record of a file when it is downloaded from the server. I am currently using a custom tag that finds the appropriate record and changes the 'used' Boolean to True, however I now realise that this occurs when the link is rendered, not when clicked.

Is it possible to get an interactive django shell using the test database?
When running tests, you can do: ./manage.py test --keepdb To run your tests, and keep the test database. Is it possible to have the django shell actually connect to it, so we can interactively access the test database the same way the Django shell can normally work with the production database? Note that the answer and its comments here imply that you can access it by doing something like: from django import test test.utils.setup_test_environment() from django.db import connection db = connection.creation.create_test_db(keepdb=True) But when I do that, my database appears to be empty when I do queries. -

Using Django how can I render in a recursive python function before each return?

How can I render the template on every step of the python function recursive call? Or how can I approach this problem?

least memory comsuming way of saving large python data into DB
I have to save a significantly large python data into the a mysql database which consists of lists and dictionaries (0.4MB) but I get memory exception during the save operation. I have already benchmarked the saving operation and also tried different ways of dumping the data, including binary format but all methods seemed to consume a lot of memory. Benchmarks below: PYTHON DATA SIZE: 0.4MB MAX MEMORY USAGE DURING JSON SAVE: 966.83MB SIZE AFTER DUMPING json: 81.03 MB pickle: 66.79 MB msgpack: 33.83 MB COMPRESSION TIME: json: 5.12s pickle: 11.17s msgpack: 0.27s DECOMPRESSION TIME: json: 2.57s pickle: 1.66s msgpack: 0.52s COMPRESSION MAX MEMORY USAGE: json dumping: 840.84MB pickle: 1373.30MB msgpack: 732.67MB DECOMPRESSION MAX MEMORY USAGE: json: 921.41MB pickle: 1481.25MB msgpack: 1006.12MB msgpack seems to be the most performant library but the decompression takes up a lot of memory too. I also tried hickle which is said to consume little memory but the final size ended up being 800MB. Does anyone have a suggestion? Should I just increase the memory limit? can mongodb handle the save operation with less memory? -
Ordering search results by date in Django
I'm trying to order the results of my search by the publication date, where the filter offers two choices: Order by lastest first or the most recent first. This is the filter that I've created so far to do that: filters.py class PubFilters(django_filters.FilterSet): CHOICES = ( ('Fecha', 'Más reciente'), ('Fecha', 'Menos reciente' ) ) ordering = django_filters.ChoiceFilter(label="Ordenar por", choices=CHOICES) class Meta: model = publicaciones fields = ['Precio', 'Categoría'] However, this returns "Cannot resolve keyword 'ordering' into field". And worse: Because I replaced the results for the filtered results (as you can see below), my pagination is suddenly broken, I can see the numbers but paginate_by isn't working. views.py class PostListView(ListView): model = publicaciones template_name = 'store/search.html' context_object_name = 'queryset' ordering = ['Promocionado'] paginate_by = 2 def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) MyFilter = PubFilters(self.request.GET, queryset=self.get_queryset()) context['filter'] = MyFilter context['filtered_items'] = MyFilter.qs context['count'] = self.get_queryset().count() context['búsqueda'] = self.request.GET.get('q') return context def get_queryset(self): qs = self.model.objects.all().order_by('id') search = self.request.GET.get('q') if search: qs = qs.filter(Título__icontains=search) return qs How could I show the filter for "ordering date" correctly? Thanks in advance! -
Django - Account Settings BooleanField
I reviewed most of the posts here related to Django and BooleanField update, but I couldn't find any related to my problem solution. I have a custom user models.py: # Own custom user model class Account(AbstractBaseUser): username = models.CharField(max_length=30, unique=True) guardianSource = models.BooleanField(default=True) bbcSource = models.BooleanField(default=False) independentSource = models.BooleanField(default=False) categoryCoronaVirus = models.BooleanField(default=False) categoryPolitics = models.BooleanField(default=False) categorySport = models.BooleanField(default=False) When I register a user it seems to register in the database all correct values for the checkboxes. The problem is when I want to edit user information I cannot see if a checkbox was checked on registering or not, it displays the checkboxes itself, but they are all empty (False). However, it correctly requests the username and displays it so I can edit it, but all the checkboxes are unchecked. views.py: def account_view(request): if not request.user.is_authenticated: return redirect('login') context = {} if request.POST: form = AccountUpdateForm(request.POST, instance=request.user) if form.is_valid(): form.save() context['success_message'] = "Updated" else: # Display the saved user details from database form = AccountUpdateForm( initial = { 'username':request.user.username, "guardianSource": request.user.guardianSource, "bbcSource": request.user.bbcSource, "independentSource": request.user.independentSource, "categoryCoronaVirus": request.user.categoryCoronaVirus, "categoryPolitics": request.user.categoryPolitics, "categorySport": request.user.categorySport, }) context['account_form'] = form return render(request, 'accounts/account.html', context) account html: {% extends 'base.html' %} {% block content %} <form class="form-signin" … -

Graphene always returning "none" in Json
Im fairly new to GraphQL and Graphene so it's hard for me to grasp whats wrong with my code. I can't even succeed with the simplest of the examples with GraphQL. Here is my code: models.py class Task(models.Model): task_name = models.CharField('Aufgabe', max_length=255) project = models.ForeignKey(Project, on_delete=models.CASCADE) done = models.BooleanField(verbose_name="Erledigt", default=False) def __str__(self): return self.task_name schema.py class Task(models.Model): task_name = models.CharField('Aufgabe', max_length=255) project = models.ForeignKey(Project, on_delete=models.CASCADE) done = models.BooleanField(verbose_name="Erledigt", default=False) def __str__(self): return self.task_name My Query in the same file: class TaskQuery(graphene.ObjectType): all_tasks = graphene.List(TaskType) def resolve_all_tasks(self, info, **kwargs): return Task.objects.all() Another Queryfunction: class Query(graphene.ObjectType): tasks = TaskQuery.all_tasks projects = ProjectQuery.all_projects This is my schema.py int the settings directory: import graphene from todo import schema class Query(schema.Query): pass class Mutation(schema.Mutation): pass schema = graphene.Schema(query=Query, mutation=Mutation) When opening GraphiQL I can see the Query in the docs, but when I try to use this query like so (for example): query { tasks{ id taskName done } } it always returns this: { "data": { "tasks": null } } Although I am pretty sure that I have entries in my Database that should be displayed there. I have checked the beginners Tutorial a view times and I can't even pass the first hurdle. … -
