Create object if doesn't exist when calling it by related_name
NOTE: I'm aware of get_or_create and it does not apply here. I have a Django app with a lot of users. One of my project apps must keep some kind of user preferences relating to this app, so in its' models.py I've created: [models.py] class UserPreferences(models.Model): user = models.ForeignKey( get_user_model(), related_name='adminpanel_preferences' ) ... (more boolean fields, integer choices etc) I don't want to use signals for creating a UserPreferences objects every time new user is being created. My idea was to only create an object when such object is somehow requested. This might sound like a perfect get_or_create use case, however I need to call this object from a template using the related_name e.g: [template.html] {% if request.user.adminpanel_preferences.hardcore_mode_enabled %} ... {% endif %} And while normally the request.user.adminpanel_preferences would return UserPreferences.None, I want it to silently create the object (using default field values) instead. Is there a possibility to achieve such behavior without interfering the User model? The UserPreferences are not global app preferences, they only refer to this particular app and I'd love to keep these two independent. I have also tried using a custom objects manager with customized get_queryset method but it doesn't seem to work when using … -
How do you delete all manytomany relationships in a model in form_valid?
I am making a booking system with Django. I want to be able to have a view to "cancel" bookings. This involves setting the participants (manytomany) of the model to None and the booked_by to none. I don't want to delete the booking as someone else might like to book it later instead. I suppose the ability to delete all relationships in manytomany for the BookingSlot would work. I would like to be able to do this in form_valid(). #views.py class CancelBookingView(UpdateView): form_class = CancelBookingForm model = BookingSlot def form_valid(self, form): form.instance.booked_by = None #This works fine form.instance.participants.all = None #This doesn't work return super().form_valid(form) So far as you can see what I have tried, it hasn't worked. Help would be much appreciated, thank you! #models.py class BookingSlot(models.Model): start_time = models.TimeField("Start Time") end_time = models.TimeField("End Time") date = models.DateField("Date") location = models.ForeignKey(Court, on_delete=models.CASCADE) booked_by = models.ForeignKey(CustomUser, on_delete=models.SET_NULL, default=None, blank=True, null=True, related_name="bookedBy_CustomerUser") participants = models.ManyToManyField(CustomUser, default=None, blank=True, related_name="participant_CustomerUser") -

Extremely Slow Django Database Querying
Currently I'm working on a Django web application using the ORM database models. But all the database queries that I make take too long (all take more than 20ms up to 17000ms using MariaDB). I even tried querying on very easy db models without any foreign keys or other relations, maybe three columns (one of them an indexed primary key) and with only a few row entries in the db table (maybe 50 rows). Even those take too long. I'm monitoring all the queries with the Django debug toolbar and it shows that even the html template engine rendering of a QuerySet with only 10 results is extremely slow (10000 - 17000ms). It's unacceptable that a simple query like the following takes longer than 20ms: SELECT * FROM Table LIMIT 10 And yes, the tables have indexed columns like the id as the primary key, I don't query from a view and I pay close attention to when I evaluate the queries. It would be acceptable if a process only queried the database like 10 times per 20-100ms each query (users won't be able to notice a latency of 200-1000ms) but since few processes do need a few more queries … -
Exception Value: Field 'id' expected a number but got <WSGIRequest: POST '/api/checkout/'>
I am having problems with passing the Post request via Vue.js in Django. It keeps getting this error when I try to fill up the form and click buy. What I am doing is that I pass it through an api and try to send it to the database and save it there. The page continues working fine, but on the background nothing happens. In console it says error 500 and when clicking on Network it shows all of that information.

why Django admin list is not updating the edit from the frontend React js form?

Select related and prefetch related for multiple reverse foreign keys with Django?
I'm currently having issues accessing values in a queryset. I have a models.py for my app that is set up like this: class Company(models.Model): name = models.Charfield(max_length=250) class Patient(models.Model): status_choices = [ ('A', 'Current Admission'), ('D', 'Discharged'), ('U', 'Unknown'), ] first_name = models.CharField(max_length=250) last_name = models.CharField(max_length=250) patient_status = models.CharField( max_length=15, choices=status_choices, null=True, default='U', verbose_name='Patient Status' ) related_company = models.ForeignKey(Company, on_delete=models.CASCADE, related_name='patients') class PatientStay(models.Model): admit_date = models.DateField() projected_dc_date = models.DateField(null=True, blank=True) is_active = models.BooleanField(default=False) stay_to_patient_relationship = models.ForeignKey(Patient, on_delete=models.CASCADE, related_name='stays') class PatientLOC(models.Model): loc_to_stay_relation = models.ForeignKey(PatientStay, on_delete=models.CASCADE, related_name='locs') level_of_care = models.CharField(max_length=30) loc_start = models.DateField(null=True) loc_end = models.DateField(null=True, blank=True) is_active = models.BooleanField(default=False) What I am trying to do is query this to get (for a particular company) the patients, their related stay (filtered for only active), and their related PatientLOC. A result like this: Company: -Patient --Stay ---PatientLOC's -Patient --Stay ---PatientLOC's -Patient --Stay ---PatientLOC's I have come up with this (less the filtering): company = Company.objects.select_related().prefetch_related('patients__stays', 'patients__stays__locs').get(id=2) Which I can loop through and get the patient and the stays, but I cannot seem to get to the LOC's for those patients. So, I can do something like this: company = Company.objects.select_related().prefetch_related('patients__stays', 'patients__stays__locs').get(id=2) patients = company.patients.all() for patient in patients: ...: print(patient) ...: print(patient.stays.all()) But … -
Django: Filtering a related field by date yields unwanted results

Most commonly when the work_end fits to something, it returns everything from WorkTime What I would like to have: for vehicle in qs: for work_time in vehicle.work_times: print(vehicle, work_time.work_start, work_time.work_end) -
How does the form set work when saving the information?
I was developing an application which used formset, but at the time I was developing, they generated multiple doubts which were, because the data that persists in the database with formset has to be given a different treatment, that is, because you have to modify the formset.instance. This is my inlineformset: ProjectFormSet = inlineformset_factory( Project, Task, form=TaskForm, fields=['type_task', 'task', 'status'], extra=1, can_delete=True ) This is my CreateView: class ProjectCreateView(CreateView): template_name = 'projects/add_project.html' form_class = ProjectForm success_url = reverse_lazy('projects:project') def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) if self.request.POST: context['formset'] = ProjectFormSet(self.request.POST) else: context['formset'] = ProjectFormSet() return context def form_valid(self, form): context = self.get_context_data() formset = context['formset'] with transaction.atomic(): self.object = form.save() if formset.is_valid(): formset.save() return super().form_valid(form) If I leave the view like this it will generate an error where it will say that formset.save() is prohibited to avoid data loss due to an unsaved related object, but if I modify the formset.instance if it is saved correctly: class ProjectCreateView(CreateView): template_name = 'projects/add_project.html' form_class = ProjectForm success_url = reverse_lazy('projects:project') def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) if self.request.POST: context['formset'] = ProjectFormSet(self.request.POST) else: context['formset'] = ProjectFormSet() return context def form_valid(self, form): context = self.get_context_data() formset = context['formset'] with transaction.atomic(): self.object = form.save() if formset.is_valid(): formset.instance … -
Wrong template rendering
I don't understand why django wont render any other template , but home with this code: urlpatterns = [ url(r'^login/', login_page), url(r'^admin/', admin.site.urls), url(r'^contact/', contact_page), url(r'^about/', about_page), url(r'$', home_page), ] But as soon as I delete the home url , every url works just fine.

Django modify objects using key=value options
I'm doing http POST processing of incoming data modifications requests (from a DataTables table) for objects in my Django environment. The POST data comes to me in key=value pairs. The problem I'm running into is that I haven't found a way to turn this into something I can use. Django objects and modifications are done like this: id = 123 item = Stuff.objects.get(id=id) item.title = "New Title" item.save() I have the following data attributes: id = 123 attribute = "title" value = "New Title" How can I use them to modify a Django object? -
Why is django not sending my email and instead giving me an error?
I'm trying to get django to send an email but I get as a return in my terminal the print from my else that says there was a problem and it wasn't sent. Why is this happening?

Django look up foreign-key form field (Newbie Question)
This is a basic question, but for some reason I cannot seem to find a straight answer, neither in the docs, nor in this forum. I am sure there must be a simple answer, but then again, I am new to Django (I know Python and databases pretty well) Scenario: 2 classes connected with a foreign key: Order --(foreign key)--> Order-approver (approver pk, fullname, title, etc.). Approver to Order is one-to-many relationship In the order entry form, I want to be able to pick/enter the approver by the full name (Django should presumably translate it into the approver id behind the scene). Ideally, there should be a look up form so I can select an approver by the name from the list How do I do that? What am I missing? -

Django: How do you compare a QuerySet with fields on a ForeignKey objects property?
I am trying to query a model against a field on a foreignkey objects property. I have the following models: class Song(models.Model): name = models.CharField(max_length=20) limit = models.IntegerField() class Recording(models.Model): song = models.ForeignKey(Song, on_delete=models.CASCADE) status = models.CharField( max_length=1, choices=STATUS_CHOICES, default=OPEN ) I would like to query Songs that have Recordings with status OPEN with a count of more than 'limit' (the field on Song). Looking over the django aggregation docs I tried something along the lines of: # View get(self): songs_count = Count('recording', filter=Q(recording__status='O')) songs = Song.objects.annotate(songs_count=songs_count) results = songs.filter(songs_count__gt=< each song.limit... >) Can someone point the way on how to build such a query?
