Massimo''s has a small typo: two paren's after 'return((.....' and a
closing paren...
EIther of these "work" in that they both give me (for example):
getName(db)
'_5'
getName(f._db)
'_5'
SO they are consistent references to some string, presumably with a
correlation to the SQLStorage object...
with this as my example:
ydb.define_table('my_table',SQLField('my_field'))
f=ydb.my_table.my_field
and using Jonathan's solution, I see this:
In [23]: getName(f._db, findAllNames=True)
Out[23]: ['_5', 'ydb', '_', '_22']
In [24]: getName(ydb, findAllNames=True)
Out[24]: ['__', '_5', 'ydb', '_22']
As you can see, the variable name you use to reference a given object is
somewhat arbitrary (it's just a reference), and "the name" (!) that you
want is also arbitrary (that is, you could use ydb.my_table or _5.my_table
equivalently; not "_" or "__" as they are transient).
This begs the question: if you are writing code "live", you can use
whatever string your heart desires (including picking the first one from
Jonathan's output that doesn't start with '_'). Actually, maybe that's
what you really want: a getName function that returns the first non-'_'
name.
So, Denes, how are you going to use these references to objects?
I guess I'm not understanding something ...
With interest,
Yarko
