Django admin page not showing user models
My admin page is working fine except when logged in it is not showing any user models. It is hindering my work as I cannot manage users. I have made custom models as shown below. Database is MySQL. models.py class User(AbstractUser): is_customer = models.BooleanField(default=False) is_restaurant = models.BooleanField(default=False) first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) class Customer(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) food_pref = models.CharField(max_length=10, default='veg') class Restaurant(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) restaurant_name = models.CharField(max_length=100, blank=False) -
waypoint infinite scroll loads the next page only once
Html: <div class="loading" style="display: none;"> <div id=circle2></div> <img class=virus id=incircle2 src="{% static 'icons\virus.png' %}" alt="virus"> </div> {% if entries.has_next %} <a class="infinite-more-link" href="?page={{ entries.next_page_number }}"></a> {% endif %} JS: var infinite = new Waypoint.Infinite({ element: $('.infinite-container')[0], onBeforePageLoad: function () { $('.loading').show(); }, onAfterPageLoad: function ($items) { $('.loading').hide(); } }); Well I found only one similar question and the recommended solution was to wrap the tag in span as: <span><a href="load-more.php" class="infinite-more-link">More</a></span> But that solution didn't work for me, thank you all for reading. -

I'm trying to deploy my first django app to heroku. I have followed all the settings steps in the guide but I run into the following Traceback during deployment: if 'DATABASES' not in config: TypeError: argument of type 'builtin_function_or_method' is not iterable If I disable collectstatic then deployment runs without errors but as soon as I try to migrate my database it raises the same error.

Django Sort By Model Function Not By Model Field
In the CourseForm I would like to sort by the longest total_duration, shortest total_duration, most total_lesson_views and least total_lesson_views. These are all Course parent class functions being done on the Lesson child class inside of the models.py file. Since these are not model fields to sort on, and instead are functions, it makes things a bit more challenging. How would you go about doing this? Courses App Forms.py: class CourseForm(forms.Form): sort = forms.ChoiceField(widget=forms.Select(attrs={'class':'form-control', 'autocomplete':'off','id':'sort'}), choices = ([('','- - - - - - - -'), ('name','Ascending'), ('-name','Descending'),('-date','Newest'), ('date','Oldest'), ('-views','Most Popular'), ('views','Least Popular'), ]), required=False) def __init__(self, *args, **kwargs): super(CourseForm, self).__init__(*args, **kwargs) self.fields['sort'].label = "Sort:" Courses App Views.py: class CourseListView(ListView): model = Course template_name = 'courses/course_list.html' sortable_attributes = ['name', 'views', 'date'] def get_queryset(self): qs = super().get_queryset() self.form = form = CourseForm(self.request.GET) if form.is_valid(): sort_query = self.request.GET.get('sort') if sort_query: match_query = sort_query if '-' not in sort_query else sort_query[1:] if match_query in self.sortable_attributes: qs = qs.order_by(sort_query) return qs def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['form'] = self.form return context Courses App Models.py: class Course(models.Model): slug = models.SlugField() name = models.CharField(max_length=120) date = models.DateTimeField(auto_now_add=True) views = models.PositiveIntegerField(default=0) @property def total_duration(self): seconds_dictionary = Lesson.objects.filter(course=self).aggregate(Sum('duration')) sec = seconds_dictionary['duration__sum'].total_seconds() if sec >= 3600: return '%2d:%02d:%02d' % (int((sec/3600)%3600), … -

How to update only specific fields in django model?
I want to update only specific fields in my model. This is my models.py class Teacher(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(upload_to='teacher/images') phone = models.CharField(max_length=15) address = models.CharField(max_length=25) salary = models.DecimalField(max_digits=20, decimal_places=2) joindate = models.DateField(auto_now_add=True) status = models.BooleanField(default=True) And this is my forms.py class TeacherForm(forms.ModelForm): class Meta: model = User fields = ['first_name', 'last_name', 'username', 'email', 'password'] class TeacherExtraForm(forms.ModelForm): class Meta: model = models.Teacher fields = ['phone', 'address', 'salary', 'status', 'image'] And this is my views.py def update_teacher(request, pk): teacher = models.Teacher.objects.get(id=pk) user = models.User.objects.get(id=teacher.user_id) form1 = forms.TeacherForm(instance=user) form2 = forms.TeacherExtraForm(instance=teacher) context = { 'teacher': teacher, 'user': user, 'form1': form1, 'form2': form2 } if request.method == 'POST': form1 = forms.TeacherForm(request.POST, instance=user) form2 = forms.TeacherExtraForm(request.POST, instance=teacher) if form1.is_valid() and form2.is_valid(): user = form1.save() # user.set_password(user.password) user.save(update_fields=['first_name', 'last_name', 'email', 'username']) f2 = form2.save(commit=False) f2.status = True f2.save(update_fields=['phone', 'address', 'salary', 'status']) return redirect('Teacher:teacher_index') return render(request, 'Teacher/update_teacher.html', context) Here I only want to update the first_name, last_name, email, username, phone, address, salary and status without affecting the password and image field. When I add the password and image field also, it works but I do not want to update password and image here. -

My models: class Post(models.Model): content = models.TextField() created_on = models.DateTimeField(auto_now_add=True) author = models.ForeignKey(CustomUser, on_delete=models.CASCADE, related_name='posts') likes = models.ManyToManyField(CustomUser, related_name='likes', through='Like') class Like(models.Model): author = models.ForeignKey(CustomUser, on_delete=models.CASCADE) post = models.ForeignKey(Post, on_delete=models.CASCADE) liked_on = models.DateTimeField(auto_now_add=True) I need to aggregate a likes statistics for each day within a given period.

How to filter by known parameters in Django?
I have several parameters with values that you can select for filtering. The fact is that the admin can add other parameters and their values should also go to the get request and be processed on the server. It looks something like this: Country -checkbox- USA -checkbox- Germany Resolution -checkbox- 1920x1080 -checkbox- 5120x ... Other options .... That is, I have several filters there and it will look something like this: products = Product.objects.filter(Q(country=request.GET.get('country') || Q(resolution=request.GET.get('resolution')) But how to make the parameters by which dynamic become dynamic? -

How to submit form using REST API for Django backend with CSRF enabled?
I'm trying to submit form to Django Web app using Java Rest Client. It doesn't work at all, I have no idea why. I was able to login using my client. I took csrftoken and sessionid cookies from login response I do submit form and provide csrfmiddlewaretoken=cookies.csrftoken.value I send csrftoken and sessionid cookies along with request. DJango backed doesn't recognise me and redirects to login. Why? I managed to figure out that for GET requests I need to send only sessionid cookie. DJango redirects to login if Cookie 'csrftoken' is sent along with GET request. What do I do wrong? It should be so trivial... -
Which ORM syntax to join three tables in Django?
I have the following three Models (tables) in my Django project: class Tool(models.Model): id = models.AutoField(db_column='Id', primary_key=True) name = models.CharField(db_column='Name', unique=True, max_length=50) class Flow(models.Model): id = models.AutoField(db_column='Id', primary_key=True) Toolid = models.ForeignKey(Tool, models.DO_NOTHING, db_column='ToolId') name = models.CharField(db_column='Name', unique=True, max_length=50) class Task(models.Model): id = models.AutoField(db_column='Id', primary_key=True) name = models.CharField(db_column='Name', max_length=50) FlowId = models.ForeignKey('Flow', models.DO_NOTHING, db_column='FlowId') I want to make ORM query that returns all info of Technology, Flow, and Task together that are related to each other (i.e. JOIN method in SQL queries). For example, I want to get something like this: [ { Tool name: ... Flow name: ... Task name: ... } { Tool name: ... Flow name: ... Task name: ... } ... ... ] Do you know what ORM sentence should I write to get that output? I really want to get the result from all of the three tables (not only from two of them)! It would be really appreciated if you provide me with the syntax related to my tables I provided above. Thanks a lot! -
