[SQLObject] How do you create a simple join?

[Stever <st...@tr...>]

Guys,

Please forgive this simple question, but I have been experimenting
forever and I can't find a solution. I checked all the docs and the FAQ.

I have two tables: "TableA" and "TableB". I want to join them in a
one-to-one relationship with a primary/foreign key. I have a mysql
database. How do I link the two tables together?

class TableA(SQLObject):
    class sqlmeta:
        fromDatabase = True
    temp1 = SingleJoin('TableB')

class TableB(SQLObject):
    class sqlmeta:
        fromDatabase = True
    temp2 = ForeignKey("ID")


TableA has primary key "ID". TableB has a foreign key "ID". The error I
am getting with the above code is:
File "./test.py", line 55
   temp1 = SingleJoin('TableB')
"IndentationError: unindent does not match any outer indentation level".
This is weird because my indentation is fine!
