How do I annotate onto a select_related model?
I am selected a related object for each object in my queryset. How can I annotate a computed value for each one? Model: class School(models.Model): name = models.CharField(max_length=255) class Teacher(models.Model): name = models.CharField(max_length=255) school = models.ForeignKey(School) class Student(Entity): name = models.CharField(max_length=255) school = models.ForeignKey(School) I want to fetch all teachers and for each one their school, and the number of students in that school. This is what I tried: teachers = Teacher.objects.select_related('school').annotate(student_count=Count('school__student')) But I can see that this is wrong as the student count needs to be per school. I'd expect to be able to do something like this with my queryset afterwards: for teacher in teachers: print(teacher.name, teacher.school.name, teacher.school.student_count) -

How to create dynamic charts with Django and Chart.js?
I'm creating a web page, and want to include a chart that shows the evolution of temperature during time. Temperature data are saved in a database every seconds. Django retrieve this data and pass it to the template. Django : def Dashboard(request): temp = Info.objects.using('wings').filter(localisation ='Wing_1').order_by('-time') time1 = [] temperature = [] for dataset in temp : time1.append(dataset.time.strftime("%Hh%M")) temperature.append(dataset.temp_wing) time1 = time1[:60] temperature = temperature[:60] time1.reverse() temperature.reverse() context = { 'time1': time1, 'temperature': temperature, } return render(request, 'Dashboard/dashboard.html',context) Template : <!DOCTYPE html> {% load static %} <canvas id="myChart" width="400" height="200"></canvas> <script src="{% static 'Dashboard/js/Chart.min.js' %}"></script> <script> var ctx = document.getElementById('myChart').getContext('2d'); var myChart = new Chart(ctx, { type: 'line', data: { labels: {{time1|safe}}, datasets: [ {label: 'Wing 1 temperature', data : {{temperature|safe}}, backgroundColor:['rgba(54, 162, 235, 0.2)'], borderColor: ['rgba(54, 162, 235, 1)'], borderWidth: 1} ]}, options: { scales: { yAxes: [{ ticks: { beginAtZero: false }}]} } }); ChartUpdate(function(){ myChart.data.datasets[0].data = {{temperature|safe}}; myChart.data.labels = {{time1|safe}}; myChart.update(); }, 5000); </script> The chart is properly rendered with the value of the database.

Django: Check in template if queryset is empty
I have found the solution for this but only by checking in views so far. I need to check in templates. My view: brands = Brand.objects.all() for brand in brands: brand.products = Product.objects.filter(brand=brand.id) And so in my template I want to show all my brands but not those which do not have any product. {% for brand in brands %} {% if brand.product is not None %} <!-- Displays brand --> {% endif %} {% endfor %} Something like that, but the code is not None doesn't work for empty querysets and it is still displaying brands with no objects in them.

Storing the username of user who submitted form using foreignkey?
I'm building an inventory system using django as a framework. I have a modelform that a logged in user will submit to place an order. all of the fields I want to be filled work with the exception of the 'store' field, which corresponds to the individual who's placing the order. I dont want the user to submit the username which is why it's been excluded in the form, I'd like to override it with 'commit=false' and add it automatically. Fairly new to django so I'm unsure whether this is a problem. So far I've added a foreignkey from the 'store' field to the user table. However when the form is submitted the 'store' field remains null. I'd like the actual username from users to be placed in this field. models.py class Sysco(models.Model): milk = models.IntegerField(null = True) store = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, null = True,) oder_date = models.DateTimeField(auto_now_add=True, blank=True, null = True,) def __str__(self): managed = True db_table = 'sysco' form.py class syscoform(forms.ModelForm): class Meta: model = Sysco exclude = ('store', 'order_date') views.py class SyscoOrder(TemplateView): template_name= "SyscoOrder.html" def get(self, request): form = syscoform(request.POST,) context = { 'form' : form, } return render(request, self.template_name, context) def post(self, request): form = syscoform(request.POST,) … -
Multilingual slug with django-translated-fields
I am trying to implement a multilingual Django website with help of django-translated-fields. The project I am working on is based on cookiecutter-django and Docker. The translation works fine for my model fields – except the slug filed. Actually translation of slug works as well but I am not able to take slug field for getting one single entry. Excerpt of voting model: class Voting(models.Model): slug = TranslatedField( models.SlugField( max_length=80, unique=True, verbose_name="Voting URL slug", blank=True ), { "de": {"blank": True}, "fr": {"blank": True}, "it": {"blank": True}, "rm": {"blank": True}, "en": {"blank": True}, }, ) Full voting model of project can be seen here. Excerpt of view: def voting(request, slug): voting = get_object_or_404(Voting, slug=slug) context = { 'voting': voting } return render(request, 'votes/single.html', context) Full view can be seen here Since Django translated fields creates slug_en, slug_de and so on I cannot find a solution for getting the slug in corresponding language. It should be obvious since documentation of Django-translated fields says: No model field is actually created. The TranslatedField instance is a descriptor which by default acts as a property for the current language's field. Unfortunately, don’t get it anyway. Any idea how I can change voting model for getting … -
Django: Get a single field from queryset in template
I have this in my view: def articles(request): brands = Brand.objects.all() for brand in brands: brand.products = Product.objects.filter(brand=brand.code) return render(request, "products.html", {'brands':brands}) And then in my template I'm trying to show all the products in groups separated by brand: <ul class="sidebar navbar-nav col-2"> {% for brand in brands %} <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" title="{{ brand.name }}" href="#" id="pagesDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> <span>{{ brand.name|lower|capfirst }}</span> </a> <div class="dropdown-menu" aria-labelledby="pagesDropdown"> {% for product in brand.products %} <a class="dropdown-item" data-toggle="tooltip" title="Testing" href="{{ product.code }}">{{ product.name }}</a> {% endfor %} </div> </li> {% endfor %} </ul> Problems are in href="{{ product.code }}" and >{{ product.name }}</a>. I don't know how to get the articles' code and name. I can acces to the whole product queryset though, but it's not useful for me. How can I achieve this? Thanks! -

How to make sure only one BooleanField is true for a single model?
I have a django project in which I have a Videos model. On my index template page I only want to show a single video, the one that has isFeatured equal to true. Whenever I change another video's isFeatured property to true, it should make that property false for the former video. I've checked out other stackoverflow questions about this but all of them are dealing with a foreign key, while my model is simpler and I think there is an easier solution for this. This is how my model looks like: class Video(models.Model): url = models.URLField(max_length=200) isFeatured = models.BooleanField(default=False) def __str__(self): return self.url -

Here is part of my Nginx configuration: location /static/ { location ~* \.(png|jpg|jpeg|gif|css|js)$ { access_log off; expires 30d; } alias /path/to/myproject/static/; } location ~ ^/favicon.ico$ { rewrite ^/favicon.ico$ /static/favicon.ico; } location /foo/ { rewrite ^/foo/(.*)$ /static/abc/$1; } location /bar/ { rewrite ^/bar/(.*)$ /static/bar/$1; } location / { fastcgi_pass myproject; include django_fastcgi_params; proxy_http_version 1.1; proxy_set_header Connection ""; } When I access https://myproject.com/foo, it will show 404 page of Django. I think it is because there is no matching location in Nginx (should end up with slash /) and no matching URL in Django's urls.py. When I access https://myproject.com/foo/, it will show index.html under myproject/static/foo/ folder, or it will be 403 Forbidden if there is no index.html. But I found that... When I access https://myproject.com/foo/abc, it will 301 Moved Permanently to https://myproject/static/foo/abc/ When I access https://myproject.com/foo/abc/, it will directly show https://myproject/foo/abc/, which are the files under myproject/static/abc/ Why these two URLs work differently? Is there any modification I should do? -
How to fix Django Oscar application.urls, when changed to custom path (/store) breaks login redirect link from checkout
Changing url(r'', include('application.urls')) to url(r'^store/', include('application.urls')) causes login redirect url to fail from checkout from cart as anonymous user. I have included LOGIN_REDIRECT_URL = '/pricing/accounts/' in settings.py. This fixes the direct login redirect url. However if an anonymous user tries to add product to cart, it is supposed to redirect to login page /store/accounts/login/?next=/pricing/checkout/ but it redirects to /accounts/login/?next=/pricing/checkout/. What is the workaround to fix this without breaking anything? -
