how to check and pass the instance of the user in my form in Django?
Hi I'm trying to create a form that accepts Log from the user however I don't know how to pass the instance of the user. I'm used to creating a CreateView for this, however since I'm planning to use customized widgets and settings, I'm using a modelform to create logs for the user. My question is is this the same way as create view to check the instance of the user? Is it still the same as what I did to my createview which is: def form_valid(self,form) : form.instance.testuser = self.request.user return super().form_valid(form) Or do I have to do something else entirely? Here is my Forms.py: from django import forms from profiles.models import User from .models import DPRLog class DateInput (forms.DateInput): input_type = 'date' class Datefield (forms.Form): date_field=forms.DateField(widget=DateInput) class dprform(forms.ModelForm): class Meta: model = DPRLog widgets = {'reportDate':DateInput()} fields = ['status','login','logout','reportDate','mainTasks','remarks'] Models.py: from django.db import models from profiles.models import User from django.urls import reverse # Create your models here. class Points(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) points = models.IntegerField(default=0, null=False) def __str__(self): return self.user.username class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.png', upload_to='profile_pics') def __str__(self): return f'{self.user.username} Profile' class Manager(models.Model): manager = models.OneToOneField(User, on_delete=models.CASCADE) def __str__(self): return self.manager.full_name class Member(models.Model): … -

Django Rest FrameWork // Conditional Model of OneToOneField
I'm developing restful API with Django Rest Framework for a statistics homepage for Admin. The service is already in progress, and I attached Django to the database that has already been created. models.py was created through managy.py inspectdb. There are no foreign keys(or OneToOneField) in the existing tables. So I am trying to create a foreign key myself in the generated models.py. But I found a table that inserts PKs of multiple tables in one column. # models.py Amodel(models.Model): consult_id = models.IntegerField(primary_key=True) # number start from 100,000 .... Bmodel(models.Model): note_id = models.IntegerField(primary_key=True) # number start from 1 .... Cmodel(models.Model): consult_note_id = models.IntegerField(primary_key=True) # saved 'consult_id from Amodel' and 'note_id from Bmodel' with unique property. ... what_is = models.CharField(max_length=7, ...) # saved 'consult' for consult table's data and 'note' for note table's data I'm trying to replace that consult_note_id in the Cmodel with OneToOneField for a smoother ORM use. Expected code below. Cmodel(models.Model): consult_note_id = models.OneToOneField(Amodel or Bmodel, on_delete=models.SET_NULL, null=True, blank=True, db_column='consult_note_id') ... what_is = models.CharField(max_length=7, ...) Expected serialized result {consult_note_id : 100001, ..., what_is : consult}, {consult_note_id : 1, ..., what_is : note}, {consult_note_id : 100002, ..., what_is : consult}, {consult_note_id : 100003, ..., what_is : consult}, {consult_note_id : 2, … -
Django Rest Framework, is it possible to organize uploaded files by associated user?
I'm planning out a backend which takes in an email associated with a file upload. Would it be possible to make the backend create a new sub-folder (with the name being the uploaded email address) in my main media folder every time a file was uploaded with a new email, or put files into the corresponding sub-folder? I've tried to look up any examples of this, but haven't come across any. Thanks! -
How to annotate a queryset with an indirectly related table?
I've got the following table: class Parent: pass class Child: fk_parent = models.OneToOneField(Parent, on_delete=models.CASCADE) class Cousin: fk_parent = models.OneToOneField(Parent, on_delete=models.CASCADE) I want to get a queryset of Child that is annotated with it's Cousin. In PSQL, I would simply write: SELECT a.*, b.* FROM child a INNER JOIN cousin b ON b.fk_parent_id = a.fk_parent_id Is this possible? -

running migrations as a part of an MS Azure app service release pipeline for a Django web app
I am wondering if anybody has experience with integrating a python manage.py migrate command into a MS Azure release pipeline. The app is being deployed using CI/CD pipeline through DevOps. In the release pipeline portion, the app is being deployed to three different stages (dev, test and prod). I have not been successful in being able to integrate the migrate command into the deployment process. I have tried achieving this by using a post deployment inline script: /antenv/bin/python /home/site/wwwroot/manage.py collectstatic /antenv/bin/python /home/site/wwwroot/manage.py migrate If I run the above commands in the sandbox environment via SSH they are carried out successfully. However, including them in the release pipeline as a post deployment script raises the following error: 2020-03-22T19:00:32.8641689Z Standard error from script: 2020-03-22T19:00:32.8727872Z ##[error]/home/site/VSTS_PostDeployment_1321584903618191/kuduPostDeploymentScript.sh: 1: /home/site/VSTS_PostDeployment_1321584903618191/kuduPostDeploymentScript.sh: /antenv/bin/python: not found /home/site/VSTS_PostDeployment_1321584903618191/kuduPostDeploymentScript.sh: 2: /home/site/VSTS_PostDeployment_1321584903618191/kuduPostDeploymentScript.sh: /antenv/bin/python: not found 2020-03-22T19:01:34.3372528Z ##[error]Error: Unable to run the script on Kudu Service.

If a timeslot is already booked, the user should not be able to book that timeslot again. models.py class futsals(models.Model): futsal_name = models.CharField(max_length=20) futsal_address = models.CharField(max_length=40) owner_email = models.EmailField(max_length=25) owner_name = models.CharField(max_length=25) def __str__(self): return f'{self.futsal_name}' class timeslot(models.Model): timesslot = models.CharField(max_length=15) name = models.CharField(max_length=15) def __str__(self): return f'{self.timesslot}' class Booking(models.Model): user_book = models.ForeignKey(User, on_delete=models.CASCADE) futsal = models.ForeignKey(futsals, on_delete=models.CASCADE) time_slot = models.ForeignKey(timeslot, on_delete=models.CASCADE) def validate_date(date): if date < timezone.now().date(): raise ValidationError("Date cannot be in the past") booking_date = models.DateField( default=None, validators=[validate_date]) def __str__(self): return f'{self.user_book}' forms.py def timeslot_validation(value): v = Booking.objects.all().values_list('time_slot') k = timeslot.objects.filter(pk__in=v) if value == k: raise forms.ValidationError("This timeslot is already booked!!") else: return value But i am not able to do the validation. Since the output of variable 'k' looks like: , , ]> the above shown timeslot are the timeslot booked by users. Now if another user enters this timeslot, it should show 'this timeslot is already booked.' now, i want this data to be shown as [(19:00 - 20:00), (18:00 - 19:00), (17:00 - 18:00)] any help would be appreciated. or if anyone could provide me a better solution for validation????? -

Django add custom search function with empty search_fields tuples
I have the following get_search_results within my ModelAdmin to search by user phone number and email: def get_search_results(self, request, queryset, search_term): queryset, use_distinct = super().get_search_results(request, queryset, search_term) try: search_string = str(search_term) users = User.objects.filter(Q(email__icontains=search_string) | Q(phone_number__icontains=search_string)) user_id_list = [int(user.pk) for user in users] queryset |= self.model.objects.filter(user__in=user_id_list) except Exception as e: pass So these search_term won't exist in my model column therefor i won't need model columns in the search_fields. But if i set my search_fields = () then it won't show the search box in the listing page. Are there anyway i can add search box to the list page without specify any columns from the model ? -

accessing javascript outside of django project
I have become the owner of an older webapp that uses django and esri/jsapi3.28. I am trying to reconstruct it in development environment. It works in production using apache2 with document root at the 'webapp' directory. I would like to create a development environment w/o apache2 and instead use django's runserver. But when trying to test in development using runserver, it cannot find the 'my_ext_js' directory. I believe this is because the document root is different? It appears I cannot change the document root. This is the webapp structure. webapp my_ext_js start.js django_app myapp django_app Again, in production, we run apache2 with mod_wsgi and document root is webapp. When running in development, I start runserver in django_app directory django_app> python manage.py runserver how can I run this using runserver in development and have it recognize/see the 'my_ext_js' folder? The production code does not have the 'my_ext_js' in a static folder. The html script just calls: <script src="/my_ext_js/start.js"></script> Any help would be great! Thanks!
