Django Model Form: Foreign Keys: Override Dropdown Menu and Allow For New Entries
I am developing a dictionary application using Django. I am having trouble successfully creating a form using Django's ModelForm class that allows users to submit new definitions to BOTH existing AND new dictionary headwords. Here is my models.py: class Headword(models.Model): headword = models.CharField(max_length=64, unique=True) class Definition(models.Model): definition = models.CharField(max_length=64) headword = models.ForeignKey(Headword, related_name="definitions_headword") Here is my forms.py: class DefinitionForm(forms.ModelForm): class Meta: model = Definition fields = ["headword", "definition"] Here is my HTML form: <form action="{% url 'dictionary:define' %}" method="post"> {% csrf_token %} {{ form }} <button type="submit">Define</button> </form> The result of all this is a form with 1) a dropdown menu containing all the headwords already in the database, 2) a text input field for the definition, and 3) a submission button. With the above code, therefore, the user is ONLY allowed to add definitions to headwords that already exist. As I said, I would like to change that and have this form such that users are able to submit definitions to BOTH existing headwords (the ones in the dropdown menu), AND new ones (ones that the user can just type in). This means I wouldn't want a dropdown menu at all in the form, but just two unconstrained text … -

(Django) How to assign unique values to each user for something linked by ForeignKey?
My group project for school has us building a school management system. I have the following models: Student: class Student(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) User.is_student = True enrolled_courses = models.ManyToManyField(Session, blank=True) def __str__(self): return f'{self.user.last_name}, {self.user.first_name}' Session: class Session(models.Model): course = models.ForeignKey(Course, on_delete=models.CASCADE) course_date_start = models.DateTimeField() course_date_end = models.DateTimeField() def session_id(self): new_session_date = self.course_date_start.strftime('%Y') return f'{new_session_date}{self.course.number}{self.pk}' def __str__(self): return f'{self.course.number} - {self.course.title} - {self.session_id()}' Assignment: class Assignment(models.Model): session_link = models.ForeignKey(Session, on_delete=models.CASCADE) created_date = models.DateTimeField(default=timezone.now) due_date = models.DateField() title = models.CharField(max_length=50) total_points = models.IntegerField() points_earned = models.IntegerField(blank=True, null=True) objective = models.TextField() def __str__(self): return self.title The problem right now is if I save one value of points_earned to a user, it saves that value to all, since they're linked by the FK. What's the best way to handle it so each Student can have their own score for each assignment? -

Python Django, Pandas: ForeignKey, his attributes and calculation
Good day, is there any solution to access the attributes of a ForeignKey inside my models.py and also to calculate inside a dataframe? class Object(models.Model): name = models.Charfield(max_length=100, null=False, blank=False) price = models.Integerfield(default=0) class Amounts(models.Model): object = models.ForeignKey(Object, on_delete=models.CASCADE) amount = models.Integerfield(default=0) Let's say the existing objects are looking something like this: id | name | price 1 | name_a | 2 2 | name_b | 4 3 | name_c | 8 Now I got a dataframe that looks something like this: id | object | amount 1 | name_a | 12 2 | name_b | 7 3 | name_c | 19 Is it possible to get the other attributes of the (via foreignkey) connected data and also to calculate inside the dataframe(in this case: price x amount)? Possible result: id | object | amount | price | calc 1 | name_a | 12 | 2 | 24 2 | name_b | 7 | 4 | 28 3 | name_c | 19 | 8 | 152 Thanks for all your help! -

How to split a string in django QuerySet object
In the view.py I am trying split an attribute value which is a long string. In a normal query: someposts = Posts.object.all()[3:5] should return: <QuerySet [object<first post>, object<second post>]> So then I query posts as follows as I need to split an attribute value (after this change I get the error): someposts = Posts.object.all().values('id', 'title', 'tags')[3:5] so it returns something like: <QuerySet [{'id': 2, 'title': 'first post', 'tags': ' X1, X2, X3,.., X10'}, {'id': 4, 'title': 'second post', 'tags': ' S1, S2, S3,.., S8'}] But I expect to receive tags as a list of stings, so what I did: splited_tags = [v['tags'].split(',') for v in someposts] for n, i in enumerate(someposts): someposts[n]['tags'] = splited_tags[n] and as the result <QuerySet [{'id': 2, 'title': 'first post', 'tags': [' X1', 'X2', 'X3',.., X10']}, {'id': 4, 'title': 'second post', 'tags': [' S1', 'S2', 'S3,.., 'S8']}] since I am passing someposts to my template: context = { 'someposts':someposts, } return render(request, 'app/home.html', context) and in home.html: {%for post in someposts %} <a class="avator" href="{% url 'user-post' post.author.username %}"></a> { % endfor %} I recieve this error: Reverse for 'user-post' with arguments '('',)' not found I think the problem is post.author.username since post is a string, … -

Django timesince function is wrong
I want to create a function that returns the list of last points per vehicle that have sent navigation data in the last 48 hours.
