django slick report and nested categories
I am using in django the following models.py: class Expense(models.Model): name = models.CharField(max_length=50) date = models.DateField(unique=False, blank=False) slug = models.SlugField(unique=True, null=True, default='') # slug = AutoSlugField(null=True, default=None, unique=True, populate_from='name') price = models.DecimalField(default=0.0, blank=True, max_digits = 20, decimal_places = 2) category = models.ForeignKey( 'Category', related_name="Expense", on_delete=models.CASCADE ) account = models.ForeignKey(Account, on_delete=models.CASCADE, verbose_name=u"Account", help_text=u"account") def __str__(self): return '{},{},{}'.format(self.name, self.date, self.price) def save(self, *args, **kwargs): self.slug = slugify(self.name) super(Expense,self).save(*args, **kwargs) def get_absolute_url(self): return self.slug class Category(MPTTModel): name = models.CharField(max_length=200) slug = models.SlugField(unique=True, null=True, default='') # slug = AutoSlugField(null=True, default=None, unique=True, populate_from='name') parent = TreeForeignKey( 'self', blank=True, null=True, related_name='child', on_delete=models.CASCADE ) class Meta: unique_together = ('slug', 'parent',) verbose_name_plural = "categories" def __str__(self): full_path = [self.name] k = self.parent while k is not None: full_path.append(k.name) k = k.parent return ' -> '.join(full_path[::-1]) The TreeForeignKey allows me to define nested categories, such as Home -> Electricity and so on. I am using the following Slick Report view.py: class TotalExpenses(SlickReportView): report_model = Expense date_field = 'date' group_by = 'category' columns = ['name', SlickReportField.create(method=Sum, field='price', name='price__sum', verbose_name=('Total category $'))] charts_settings = [ { 'type': 'bar', 'data_source': 'price__sum', 'title_source': 'name', }, ] It works but I would like to sum only level 1 categories.

How to install both Java 11 and Python 3.7 in Docker container using Dockerfile
I have a Django project, from inside which I am executing a jar executable file. But I am having trouble installing both Java 11 and Python using the Dockerfile.

Django unique_together() for field1 and field2 and vice versa (field2 and field1)
It's possible to create duplicate thread with same first_person and second_person using unique_together() in django. class Meta: unique_together = ['first_person', 'second_person'] But just like that, Is it possible to make it work for same second_person and first_person too ? For example if first_person is abc@gmail.com and second_person is xyz@gmail.com then I can't create duplicate value but if I try to make second_person is abc@gmail.com and first_person is xyz@gmail.com then it again creates thread with same person that I dont want. Please let me know how to fix this. -

I have been using DRF since a long time now but I have been opting for old school ModelForm (forms.ModelForm) method for user registration. I just want to know that is it necessary to use modelForm for user Registration or we could use serializer as well like we do for all the APIs ?

Django Admin Inline Form Fails in Test but Works in Admin Interface

Additional save button on Django admin pages
How can you add an extra Save-button on admin list view pages, like shown on the image, that saves the changes but also does something extra before or afterwards? I know that it possible to achieve this functionality via "actions" but it is cumbersome to select the correct action from select-box, when you need to do it repetitively. It would be beneficial to be able to add extra save button both to the list view and the change view. -

I have a model of users and a model with a survey in which users express their opinion with a vote with an integer number that identified a particular color of eyes. A srcID user describes the color of the eyes of a dstID user according to his opinion. A user can votes himself. It's possible that a user doesn't receive any votes so there isn't a tuple with dstID equal to his ID. The integer number of eyeColor rapresent a specific color, for instance: 1 => blue eyes 2 => lightblue eyes 3 => brown eyes 3 => green eyes ecc. class user: userID = models.AutoField(primary_key = True, auto_created = True, unique = True) name = models.CharField(max_length=100) class survey: srcID = models.ForeignKey(user, on_delete = models.CASCADE, related_name='hookSrc') dstID = models.ForeignKey(user, on_delete = models.CASCADE, related_name='hookDst') eyesColor= models.IntegerField() My goal is to annotate in the user model the most frequent type of eyeColor voted, so the eyesColor that other people think is the eyesColor of that user. If a user doesn't receive any votes I want to annotate 0. In case there are more than one color with the same voting frequency, if the user has voted himself (tuple with srcID = … -
Will I need to create a virtualenv every time I runserver with Django?
Currently taking CS50 Web Programming with Python and Javascript. I'm on the Week 3 Django lecture and trying to follow along but I'm running into trouble while trying to run python manage.py run server. I'm getting the "ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?" error. I'm using Windows, Django IS installed and I've reinstalled it multiple times. I've found a workaround by following the steps from https://www.youtube.com/watch?v=eJdfsrvnhTE&t=296s to set up a virtual env and can proceed after that, but in the lecture Brian doesn't need to setup a virtual env? It just loads straight through for him? Yes I have scoured through reddit, stackoverflow, youtube, and other articles online before asking this here. It's not too much trouble to do so but I'm just wondeirng why he didn't need to make a virtualenv and if I'm actually going to have to make a virtual env for every Django project going forward? Is it because things have changed with python/pip/Django? I would just find it more convenient if I could just run the run server command without having to run the extra 4 commands … -
