Django ForeignKey: using in reverse order. What form element is shown-CodePudding

I have a student project relationship. One student can be assigned to only one project. A project can have multiple students

The following is my student and Project model

class Student(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)
    def __str__(self):
        return self.first_name

class Project(models.Model):
    name = models.CharField(max_length=30)
    def __str__(self):
        return self.name

How to get create the relationship in this case

Good day!

add following line:


class Project(models.Model):
    name = models.CharField(max_length=30)
    
    def __str__(self):
        return self.name

class Student(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)
    project = models.ForeignKey(Project, on_delete=models.CASCADE) # This

    def __str__(self):
        return self.first_name

This way a student can have only one project, project can have many students.
