Wrong expactation using Markup()?

Hi,

I'm trying to inject HTML into my templates like this:

    content = Markup(rst_to_html(content))
    return render_template('show.html', content=content)

and then
<htmlblah>
{{ content }}
</htmlblah>

It's like the Markdown-snippet (http://flask.pocoo.org/snippets/19/)
but using rst.
Problem is, that I still have to things like

{{ content|safe }} or {% autoescape false %} {{ content }} {% endautoescape %}

to get the unescaped, formatted output.

Am I doing something wrong, or are just my expactations regarding
Markup() wrong?

Regards,
Ben

Hmm, problem kind of solved.

Problem was I read the content from a couchdb (ViewResults)-object and
wrote it back in there.
The Markup() object somehow gets lost when writing back. When I
transfer the data to a new dict after using Markup() everything is
fine.

If someone had an explanation why the Markup() gets lost, I'd be
really willing to hear it :)

CouchDB uses JSON for transfer and can only transport certain objects. 
Markup itself is an unicode string and a json encoder will silently 
convert it into a unicode string.

Ah, ok. So still a problem of wrong expectations :P
Thanks!

Markup is working fine and so does the usage you pasted above, maybe you 
could paste some more code to reproduce that.  I suppose you are losing 
the markup information somewhere.
