Description
The Variable
class does not accept empty constants ("") in templates. The error message is:
Could not find variable at start of ""
I traced the error to the __init__
method of FilterExpression
. The attached diff fixes the error. I think some of the surrounding if <var>
statements should also be rewritten as if <var> is not None
, but the diff is restricted to fixing this bug.
