Get the list of related objects in django
I have 3 models: class Node(models.Model): ID = models.DecimalField(max_digits=19, decimal_places=10) name = models.CharField(default='node', max_length=32) connexion = models.CharField(max_length=255) # Many2one fields | Foreign keys: firm = models.ForeignKey('firme.Firme', on_delete=models.CASCADE, null=True, blank=True) class ScheduledAction(models.Model): date = models.DateTimeField(default=datetime.now, blank=True) firm = models.ForeignKey('firme.Firme', on_delete=models.CASCADE, null=True, blank=True) node_ids = models.ManyToManyField(Node) I want in ScheduledAction form to show, for a selected firm, the list of its related nodes. Normally I should do this by get: class ScheduledActionForm(forms.ModelForm): date = forms.DateTimeField() firm = forms.ModelChoiceField(queryset=Firme.objects.all()) node_ids = forms.ModelMultipleChoiceField(queryset=Node.objects.get(firm_id=firm.id), widget=forms.CheckboxSelectMultiple) class Meta: model = ScheduledAction fields = [ 'date', 'firm', 'node_ids' ] But I got this error: AttributeError: 'ModelChoiceField' object has no attribute 'id' How can I fix this? -
Django websockets auth
I use tornado + sockjs for websockets and Django rest framework for main app. Also I use rest-framework-jwt for auth on Django app. Now I have to determine user in tornado. How I see it: 1. User send jwt in message when sockjs connected to tornado server. 2. Tornado server parse jwt and determine is valid jwt or not? But for this solution I have to read database. But this operation is sync which is not good, because tornado is async. Also I thought use Celery. When user connected to tornado, tornado creats task for celery and in this task jwt will be parsed. In that case solution is not blocking tornado. But how then to notice user via websockets about check jwt? -
Changing border of group of cells in excell to thick box border with xlsxwriter
I am trying to change box border of some excell cells to "Thick Box Border". I am using django 1.9.5 and python 2.7.5 and xlsxwriter for excell. import xlsxwriter workbook = xlsxwriter.Workbook('bordertest.xlsx') worksheet = workbook.add_worksheet() format = workbook.add_format({'border': 2}) worksheet.write('B3', 'Border2', format) This is working for one cell. But i want to apply thick box border around some group of cells like below. I couldn't figure it out. I want to apply thick border to rectangle block of cells between B4-G4 & B8-G8. Between red dots the lines will be bold. But cells in the red dotted rectangle area, will be normal border. So different color group of cells will be seperated with thick border. -
Remove decimal point from number passed to django template?
I am using stripe to process payments with a django web application. The prices in the database are stored in decimal format, e.g. 100.00 Stripe takes this as $1, and ignores everything to the right of the decimal point. I need to remove the decimal point when passing this number to Stripe. Can I do this within the django template? -

Django models field import
As an extension of the polling app tutorial from the Django docs, I'm creating user profiles and I want to grab a particular user's response to each question and store it in the database, and be able to list all the responses of a user to all the questions when the user signs in. And also all responses to a question from all the users. The tutorial creates two models : Question and Choice.(many2many). But how do I attach a particular question's choice selected by a particular user, to that same User? Will I have to change the built-in User model for that? In particular, the problem I faced was I tried creating a new model called 'Answers'. It can have either 'User' as the foreign key' OR 'Question' as the FK. But a particular answer belongs to BOTH - USER & QUESTION, i.e, it is the answer to a particular QUESTION marked by a particular USER. So that answer should have reference to BOTH the QUESTION (to which it is the answer/choice) and the USER (who marked that as her/his answer/choice to that particular QUESTION). I'm unable to figure out how to have the 'Answer' link BOTH to the … -
How to do group by on a different attribute and sum on a different attribute in Django?
models.py: class Student(models.Model): total_fees = models.PositiveIntegerField(blank=False) roll_number = models.PositiveIntegerField(blank=False) class StudentTransaction(models.Model): student = models.ForeignKey(Student, on_delete=models.CASCADE, blank=False) amount = models.PositiveIntegerField(blank=False) timestamp = models.DateTimeField(auto_now_add=True, blank=True) admin.py: class StudentTransactionModelAdmin(admin.ModelAdmin): list_display = ['__str__', 'time', 'amount'] def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == 'student': x = StudentTransaction.objects.order_by().annotate(Sum('amount')).filter(amount__sum__lt=student__total_fees) kwargs["queryset"] = [i.student for i in x] return super().formfield_for_foreignkey(db_field, request, **kwargs) While doing annotate I want to get all transaction amounts summed up for every student in the function formfield_for_foreignkey. I want the actual Student objects, so this can't be done using values. To make it simpler, consider that there are 3 Student objects. One of them has made 2 transactions, another one has made 4 transactions, and the third one hasn't made any transactions. The sum of transaction amounts per student doesn't exceed the student's total_fees. The formfield_for_foreignkey should return all Student objects those who haven't paid their fees yet. The condition is: sum(<all transactions of each student>) is less than <total_fees of that student> Note: Some details are intentionally removed to keep the code as short as possible. If something is missing or will produce an error, do report it. -

Queryset based on ForeignKeys in Django
While learning Django I am creating an example app in which I have two types of users; students and educators. Educators can create Study sections and students can choose which they would like to participate in (just a BooleanField yes or no).

To do this for each study section I need to query all of the student users who marked "yes" to participate in that study section. I am a bit stuck on how to use Django's QuerySet methods to do this.
