    <p>I am having the hardest time with my views and formsets saving. I have come to realize that views are my weakness in Django. I have been working on this for the past few months and writing and rewriting the code. I know this is the best way to learn. Luckily my team gave me this project to learn from. But I still don't know where I am going wrong.</p> <p>If anyone here sees where I am off or pointing me into the right direction, I'd greatly appreciate it. I'm searching for best resources to get stronger in this area. </p> <p>Here is my Views:</p> <pre><code>from django.conf import settings from django.views.generic import View from django.views.generic

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
