[albatross-users] Having trouble implementing pagination

[Sheila King]

OK, I'm tearing my hair out and am about to give up for tonight and go to 
bed. LOL. Should have probably done that a couple of hours ago. Oh, well.

I just can't seem to get pagination with the al-for tag to work.

I understand that I need some sort of sequence type that has both __len__ 
and __getitem__ methods.

I'm returning a result of several rows in a MySQLdb object using the 
Dictionary Cursor types.

A typical query result, after using fetchall() to get all the results, 
would be something like this:

mydicts = ({'a': 1}, {'b': 2})

I have a class, that I use on individual dictionaries, such as the result 
of a fetchone() command, that works really nicely. That class works fine by 
itself.

However, today I tried to make some kind of a class that is a list of those 
dictionary objects, because I want to iterate over them and use pagination. 
But I am totally unable to have any kind of success at this.

I tried this:

class myclass(list):
    def __getitem__(self, x):
        return self[x]

But the above TOTALLY does not work and just recurses like mad until I hit 
the maximum recursion level.

I tried a bunch of other stuff too. <sigh>

If someone can toss me a hint, I'd sure appreciate it.

Thanks,
