Overriding class member variables in Python (Django/Satchmo) | 762,165 | <p>I'm using Satchmo and Django and am trying to extend Satchmo's Product model. I'd like to make one of the fields in Satchmo's Product model have a default value in the admin without changing Satchmo's source code. Here is an abbreviated version of Satchmo's Product model:</p>

site_field.editable = False
site_field.default = 1

<p>But this is a nasty habit and could cause problems; arguably less maintainable than just patching Satchmo's source directly.</p>... | 1 | 2009-04-20T15:52:20Z | [

for i, obj in enumerate(Blog.objects.order_by('-pubDate')):

How do I store a string with a `"` in it? | 763,654 | <p>I want to have a JSON object with the value of an attribute as a string with the character <code>"</code>.
For example:</p>

With Python.</p>

<p>As for how to do it in python, you need to provide a more detailed explanation of how you are building your <code>JSON</code> object. For example, let's say you're using no external libraries and are doing it manually (ridiculous, I know), you would do this:</p>
