I need to make a page that can save a lot of students information for example when we want to add a new user/student we should enter some required field..actually I can add and save a name,last name,NO, etc...but I can't save a many lessons for one student like this picture.
my page
what I want is a view for my project . I try a lot Algorithm but I can't save to data base / admin page.
my admin.py
from django.contrib import admin
from .models import Students
class StudentsAdminInline(admin.TabularInline):
model =Students
class StudentsAdmin(admin.ModelAdmin):
list_display = ["__str__","o_no","f_name","l_name","University","date","timestamp","update"]
inlines = [StudentsAdminInline]
admin.site.register(Students)
my model.py
from django.db import models
class Students (models.Model):
email=models.EmailField()
f_name=models.CharField(default="",max_length=50)
l_name = models.CharField(default="",max_length=50,blank=False)
o_no=models.CharField(default="",null=False,max_length=50)
University=models.CharField(default="",max_length=50)
date=models.DateField(editable=True,null=True)
timestamp=models.DateTimeField(auto_now_add=True,auto_now=False)

Code=models.DecimalField(max_digits=2, decimal_places=1,null=True)
Success=models.CharField(default="",max_length=50,blank=False)
def __str__(self):
return '{}'.format(self.id)

class student_form_admin(forms.ModelForm):
class Meta:

You will need to use Django Formsets. Take a loot at Django Formsets.
Or if you want to use only django admin, you should change your code to:
admin.py:
from django.contrib import admin
from .models import Student, Lesson
class StudentAdminInline(admin.TabularInline):
model =Lesson
#admin.register(Student)
class StudentAdmin(admin.ModelAdmin):
list_display = ["__str__","o_no","f_name","l_name","University","date","timestamp","update"]
inlines = [StudentAdminInline]
models.py:
from django.db import models
class Student (models.Model):
email=models.EmailField()
f_name=models.CharField(default="",max_length=50)
l_name = models.CharField(default="",max_length=50,blank=False)
o_no=models.CharField(default="",null=False,max_length=50)
University=models.CharField(default="",max_length=50)
date=models.DateField(editable=True,null=True)
timestamp=models.DateTimeField(auto_now_add=True,auto_now=False)
update=models.DateTimeField(auto_now_add=False,auto_now=True)
def __str__(self):
return '{}'.format(self.id)
class Lesson (models.Model):
student=models.ForeignKey(Student,related_name='items')
name=models.CharField(default="",max_length=50,blank=False)
Code=models.DecimalField(max_digits=2, decimal_places=1,null=True)
Success=models.CharField(default="",max_length=50,blank=False)
def __str__(self):
return '{}'.format(self.id)
forms.py:
from .models import Student, Lesson
class students_form_admin(forms.ModelForm):
class Meta:
model=Student
fields=["__str__","o_no","f_name","l_name","University","date","timestamp","update"]
class student_form_admin(forms.ModelForm):
class Meta:
model=Lesson
fields=["Lessons","Code","Success"]

Alright, so I'm going to suggest that you read through how to create a view. The Django website has a lot of information that is incredible helpful. Here is the documentation for creating views.
As for saving to a database. Here is the documentation on setting up and using databases with your project. This link will show you how to use models and objects to save data from your view.
The Django website has all kinds of information that can help you.
