I created a scatter chart by using Google Charts in my Django project. It is working clearly but in the toolbox, the legends name does not show just number is displaying. How can I display it?

how to only accept requests with users over the age of a certain age in Django rest framework
the title probably seems very confusing but I will explain it. I am trying to make a feature in my Django rest framework project of which when you sign up it calculates your age then if you are old enough your account is made but if you are not it gives an error of you are not old enough. so my 2 questions are: how would you calculate a users age using their date of birth how would you only create account which have users over the age(in my case I would like to make the threshold 13) I have seen another question on stack overflow here. I added the calculation on the top answer to my models.py but It gives an error in self.birthday(which in the answer would be date_of_birth) saying Unexpected field type(s): (DateField) Possible type(s): (timedelta) (date) -
How to debug Django using daphne
I recently switched from gunicorn to daphne for my Django application, and I am finding it impossible to debug now. When using gunicorn, if I made a mistake the Django debug page would appear, and I could find the issue. With Daphne, I am just getting the nginx error page until I can manually track down the error... Is there a way to make this behave like gunicorn and show the django debug page? -
Django: How do I exclude related fields when using `._meta.get_fields()`?
I'm trying to write a view in Django to export my model data in a csv file. The problem is that I can't figure out how to exclude related fields. Currently, when I run model._meta.get_fields(), the function returns the model's fields and the related model's field, so my view throws an error when I use getattr() using the related field's name. I tried using .is_related() to exclude related fields, but that also excludes the model fields (like ForeignKey). When I call the field name, I can see the class name is ManyToOneRel, but I can't figure out how to access that attribute. Does anyone know how to exclude related fields or figure out if a field is a related model's field? My view is below. Thanks to anyone that can help! class CSVExportView(View): template_name = 'medrec_v2/csv_export.html' def get(self, request, *args, **kwargs): model_list = [m for m in apps.app_configs['medrec_v2'].models if '_' not in m ] # print(model_list) context = {'model_list':model_list} return render(request, self.template_name, context) def post(self, request, *args, ): model_name = request.POST.get("model-sel") model = apps.get_model(app_label='medrec_v2',model_name=model_name) content_type = 'text/csv' datecode = datetime.today().strftime('%y%m%d') file_name = f'{datecode}_medrecv2_{model_name}.csv' response = HttpResponse(content_type = content_type) response['Content-Disposition'] = f'attachment; filename="{file_name}"' header = [f.name.split('.')[-1] for f in model._meta.get_fields() if … -

filtering by one-digit number in MultiSelectField
I have MyModel: class MyModel(models.Model): ELEMENTS_CHOICES = Choices( (1, 'element1'), (2, 'element2'), (3, 'element3'), (4, 'element4'), (10, 'element10'), (12, 'element12'), ) elements = MultiSelectField( _('elements'), choices=ELEMENTS_CHOICES, blank=True, ) I have also some MyModel objects with elements values like below: obj1.elements = ['1', '2', '3', '10', '12'] obj2.elements = ['1', '3', '10', '12'] obj3.elements = ['1', '3', '10'] obj4.elements = ['2'] How do I filter through this field values? The filter I tried to use is: search_id = 2 MyModel.objects.filter(elements_icontains=search_id) It was ok before the two-digit numbers appeared in the MyModel field choices. Now it returns obj1, obj2 (because 12 is on the list, and it contains 2 as the part of it) and obj4. I would like to search just for values with 2 number and get just obj1 and obj4 as results. Currently, the results are objects that contains 2 and 12. What is the right way to filter this field? -

Calling a Python C extension blocks all Django processes/users
Problem I have written a Python C extension (ftaCalculate) in order to improve the performance of a given function that was previously written in pure Python. I have been able to increase the execution speed by a factor of x10, so no problem on this site. import ftaCalculate cs_min = ftaCalculate.mcs(N, tree) However, I am executing this function in a Django framework. The problem is that, until the function ftaCalculate.mcs does not finish, I cannot do anything on my website. When the function was in Python, I could press other buttons and access other URLs. This is specially a problem when several users are working at the same time in the website, because the other users cannot do anything while this function is being executed. Actually, you can see in the following image that one core is at 100% when running the function: Question Do you know any way I could call my Python C extension without "freezing" the Django framework? Possible workaround In the worst case, I could try calling this part of the code with Celery. However, I would prefer another solution, since I do not need Celery when running in pure Python. -
Template inheritance doesn't inherit encoding?
I have managed to deploy my first django app to heroku. After some struggle I got it to work and the main site is loading well however other views result in Server Error 500. Firefox console spits out this: '''The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol.''' Now I'm the base.html template I am using on the main page which is loading fine has a charset="UTF-8" metatag defined. I'm extending that template for every other view in my app so I assume this tag should be also included. When I was running that locally then the templates were working fine. Any ideas on how to solve this? -
