How to do not repeat?

Question

Django

I have two models
file models.py

from django.db import models
# -*- coding: UTF-8 -*-

class LessonOne(models.Model):
    russia = models.CharField(max_length=250)
    english = models.CharField(max_length=250)
    buttons = models.TextField()
    def __str__(self):
        return self.russia

class LessonTwo(models.Model):
    russia = models.CharField(max_length=250)
    english = models.CharField(max_length=250)
    buttons = models.TextField()
    def __str__(self):
        return self.russia'

In views.py file

def listdataOne(request):
    data = LessonOne.objects.all()
    return render(request, 'fighter/listdataOne.html', {'data': data, "amount": len(data)})

def listdataTwo(request):
    data = LessonTwo.objects.all()
    return render(request, 'fighter/listdataTwo.html', {'data': data, "amount": len(data)})

In index.html

<li><a href="/fighter/listdataOne">First lesson.</a></li>
<li><a href="/fighter/listdataTwo">Second lesson.</a></li>

Is it possible somehow to replace the listdataOne and listdataTwo functions with one function and make one HTML template for it?

# -*- coding: UTF-8 -*-
Should be the very first line.
You need one model:

class Lesson(models.Model):
    lesson_number = models.IntegerField()
    russia = models.CharField(max_length=250)
    english = models.CharField(max_length=250)
    buttons = models.TextField()
    def __str__(self):
        return self.russia

And, accordingly, one function for the output:

def listdata(request, lesson_number):
    data = LessonOne.objects.filter(lesson_number=lesson_number )
    return render(request, 'fighter/listdataOne.html', {'data': data, "amount": len(data)})

But judging by the question, I can conclude that you have not studied the official tutorial. Start from there.
