I am learning django and I really can't solve this error, I tried modifying every file but I can't find where the issue is.
Error: OperationalError at /topics/ no such table: pizzas_topic
I have to mention that this exercise is from Python Crash Course 2nd Edition
Thanks
Here is the code from my project:
base.html:
<p>
<a href="{% url 'pizzas:index' %}">Pizzeria</a> -
<a href="{% url 'pizzas:topics' %}">Pizzas</a>
</p>
{% block content %}{% endblock content %}
index.html
{% extends "pizzas/base.html"%}
{% block content %}
<p>Pizzeria</p>
<p>Hi</p>
{% endblock content%}
topic.html
{% extends 'pizzas/base.html' %}
{% block content %}
<p>Topic: {{topic}}</p>
<p>Entries:</p>
<ul>
{% for entry in entries %}
<li>
<p>{{entry.date_added|date:'M d, Y H:i'}}</p>
<p>{{entry.text|linebreaks}}</p>
</li>
{% empty %}
<li>There are no entries for this topic yet.</li>
{% endfor %}
</ul>
{% endblock content %}
topics.html
{% extends "pizzas/base.html" %}
{% block content %}
<p> Topics</p>
<ul>
{% for topic in topics %}
<li>
<a href="{% url 'pizzas:topic' topic.id %}">{{ topic }}</a>
</li>
{% empty %}
<li>No topics have been addet yet.</li>
{% endfor %}
</ul>
{% endblock content %}
