Thanks, that solves my problem.

If you successfully get to render_to_response (or similar) the template renderer will silently swallow errors.
If you want the error to stop rendering and either print an error or a 500 or something similar, test it in the view before rendering.

Assuming you have an entry (or list of entries I guess) in your view:

for entry in entries: #for a list of entries
   try:
       entry.state
    except:
       return HttpResponse(status = 500)

or something similar

I have some custom functions in model classes which processes some data, and add custom attribute to the model. Thing is, I do not know how could I raise an exception if this functions that are accessed when the template is generated (the error seems to be only silent, so it will process the template further but gives NO ERROR )

In the template

    {{ entry.state }}

In the model:

    @property

    def state(self):

        somedict = {'a': 111}

        try:

           print somedict['b']

        except Exception as e:

           FATAL_ERROR

What should I put in the place of fatal_error so that the template processing should stop immediatelly, or gives some exception to the render function ? 

Thanks
