Django Admin Site two model combine into 1 model using foreignkey

Question

I have this table StudentProfile

and table StudentEnrollmentRecord, I just want to add an column before the Student User just like the picture below,

this is my code in model.py

class StudentProfile(models.Model):
   LRN = models.CharField(max_length=500,null=True)
   Firstname = models.CharField(max_length=500,null=True,blank=True)
   Middle_Initial = models.CharField(max_length=500,null=True,blank=True)
   Lastname = models.CharField(max_length=500,null=True,blank=True)

class StudentsEnrollmentRecord(models.Model):
    Student_Users = models.ForeignKey(StudentProfile, related_name='+', on_delete=models.CASCADE,null=True)
    School_Year = models.ForeignKey(SchoolYear, related_name='+', on_delete=models.CASCADE, null=True, blank=True)
    Courses = models.ForeignKey(Course, related_name='+', on_delete=models.CASCADE, null=True, blank=True)
    Section = models.ForeignKey(Section, related_name='+', on_delete=models.CASCADE, null=True,blank=True)
    Payment_Type = models.ForeignKey(PaymentType, related_name='+', on_delete=models.CASCADE, null=True)
    Education_Levels = models.ForeignKey(EducationLevel, related_name='+', on_delete=models.CASCADE,blank=True,null=True)

and this is my code in admin.py

class StudentsEnrollmentRecordAdmin(admin.ModelAdmin):
    list_display = ('Student_Users', 'School_Year', 'Courses', 'Section', 'Payment_Type', 'Education_Levels')
    ordering = ('Education_Levels',)
    list_filter = ('Education_Levels','Section','Student_Users')

Answer 1

You will need to define a separate function in your Admin class to retrieve the column from your related object:

class StudentsEnrollmentRecordAdmin(admin.ModelAdmin):
    ...
    def lrn(self, obj):
        return obj.Student_Users.lrn

and then use it in list_display

list_display = ('lrn', ...)

I also recommend using list_select_related so it doesn't query DB for every row.

class StudentsEnrollmentRecordAdmin(admin.ModelAdmin):
    ...
    list_select_related = ('Student_Users')
