django display textfields

In HTML, newlines between text don't imply a newline in display; you need to use HTML to insert the newline. The most straightforward way is with the <br /> tag, although there are other methods as well.

Django has a template filter for this: use |linebreaks. Here's the Documentation.

So, change:

{{ rev.myTextField }}

to:

{{ rev.myTextField|linebreaks }}
