I'm trying to figure out an issue here which sounds sort of similar.
I've got a class in UpLib:
class UpLibQueryParser (PythonMultiFieldQueryParser):
in one of the methods (getFieldQuery), it needs to reparse the input,
so I create a new instance of my class:
newparser = self.__class__(self.fields, self.getAnalyzer())
and then cast it to a QueryParser so that I can call "parse()" on it:
qp = QueryParser.cast_(newparser)
But I get an exception at this point:
File "/local/share/UpLib-1.7.4/code/uplib/indexing.py", line 320, in
getFieldQuery
qp = QueryParser.cast_(newparser)
TypeError: <UpLibQueryParser: [EMAIL PROTECTED]>
Above, I'm using "self.__class__" because I also create subclasses of
this class, and I want an instance of the most specific subclass
created.
How about using type(self)(...) instead ?
Andi..
