Everything was working perfectly uptil the admin part,I was able to log in as admin , but when I tried to put that view in the regular template, I was getting the following error:

Error during template rendering

In template /home/vatsal/projects/hellowebapp/hellowebapp/collection/templates/index.html, error at line 4

Invalid block tag: 'endfor', expected 'endblock'

This is my index.html file:

   {% extends 'layouts/base.html' %}
   {% block title %}Homepage - {{ block.super }}{% endblock %}
   {% block content %}
       {% for thing in things}
       <h2>{{ thing.name }}</h2>
       <p>{{ thing.description }}</p>
       {% endfor %}

   {% endblock %}

Why does it say no such table collection_smartphone? Where should I add it?

#2

No such table means that the database doesn’t exist. You can log into admin even without a database… was the table it’s mentioning showing up in the admin list?

#3

I’m able to see the admin page with the authentication and collection part and when I click on add , I get to the forms and type stuff ,but when I click save, I get the same error. Where and how do I add that table ?

#4

Corrected it by doing

python manage.py syncdb

python manage.py makemigrations

and then

python manage.py migrate.

So do I have to do this everytime I make a change?

#5

Every time you make a change to models.py, yes (actually should just need to do makemigrations and migrate.) Basically, models.py is a plan to the database… when you change the plan, you need to change the underlying database too to match. :)

Thank you ,got it :D!
