Question

I have a model that looks like this:

class Foo(ndb.Model):
    bar = ndb.TextProperty(required=True)
    # other properties

I’m using jinja2 for templating:

{{ bar|safe }}

I ‘put’ in this:

<p>I think it is always going to be challenging planning a wedding in a foreign country. 1234 Weddings was able to pre-arrange everything before our arrival and even meet us at the airport to attend to last minute details.<br> The wedding itself was even more amazing than we could have imagined and flawless. For our day, 1234 Weddings became a part of our family and our memories. We are so greatful for the professional communication and creativity that made our day so special.</p>

And ndb mangles the text, outputting this:

<p>I think it is always going to be challenging planning a wedding in a for=
eign country. 1234 weddings was able to pre-arrange everything before our a=
rrival and even meet us at the airport to attend to last minute details.<br=

lawless. For our day, 1234 Weddings became a part of our family and our mem=
ories. We are so greatful for the professional communication and creativity=
 that made our day so special.</p>

This only happens on my deployed site. The identical code on localhost doesn’t produce this issue.

Possibly relevant:

• My local app engine doesn’t have a persistant datastore.
• bar was originally of type ‘StringProperty’. I noticed the issue after I changed the type to ‘TextProperty’, but there wasn’t extensive testing before the change so it’s possible the issue existed prior to that.

Any help would be appreciated.
TIA.

There is a bug in the blobstore upload handler that causes encoding problems with text submitted at the same time, comments here have a patch that has worked for me in the past: http://code.google.com/p/googleappengine/issues/detail?id=2749
