Problem with the website!

So I made everything work but the content showed something else, so i fixed that but it showed the how to use strings instead, it really was a easy fix, i just had to order it as 0. But at the time I thought that deleting it was a much better idea. so when that happend I could no longer go into python basics. and see the things. Here is my code.

models.py

from django.db import models

class Course(models.Model): created_at = models.DateTimeField(auto_now_add=True) title = models.CharField(max_length=255) description = models.TextField()

def __str__(self):
    return self.title

class Step(models.Model): title = models.CharField(max_length=255) description = models.TextField() content = models.TextField(blank=True, default='') order = models.IntegerField(default=0) course = models.ForeignKey(Course)

class Meta:
    ordering = ['order',]

def __str__(self):
    return self.title

step_detail.html:

{% extends "layout.html" %}

{% block title %}{{ step.title }} - {{ step.course.title }}{% endblock %}

{% block content %} <article> <h2>{{ step.course.title }}</h2> <h3>{{ step.title }}</h3> {{ step.content|linebreaks }} </article>

{% endblock %}

views.py:

from django.shortcuts import get_object_or_404, render

from .models import Course, Step

def course_list(request): courses = Course.objects.all() return render(request, 'courses/course_list.html', {'courses': courses})

def course_detail(request, pk): course = get_object_or_404(Course, pk=pk) return render(request, 'courses/course_detail.html', {'course': course})

def step_detail(request, course_pk, step_pk): step = get_object_or_404(Step, course_id=course_pk, pk=step_pk)

return render(request, 'courses/step_detail.html', {'step': step})

course_detail.html:

{% extends "layout.html" %}

{% block title %}{{ course.title }}{% endblock %}

{% block content %} <article> <h2>{{ course.title }}</h2> {{ course.description }}

<section>
    {% for step in course.step_set.all %}
        <h3>{{ step.title }}</h3>
        {{ step.description }}
    {% endfor %}
</section>   

</article>

{% endblock %}

Sorry if what I wrote here looks weird I don't know how to use this!

If anything is unclear just ask me!
