all the value i get from sophy is None while key was correct about sophy HOT 5 CLOSED

you're not calling random_insert().

from sophy.

Might be helpful to blow away that database directory before running, just to ensure you're starting from a clean slate. Then also to ensure you call random_insert() before show().

Running locally, I get:

In [7]: random_insert()

In [8]: show()
cqecvp 8867
dvapye 6724
gixnbg 5257
mlubrf 3087
mqvitu 9890
oxckzx 6149
pxdxus 8971
rpdwll 4030
sksigm 8399
yaiubf 6309

from sophy.

sorry, i havnt described clearly, i use the same script run twice, the first time i run random_insert, while the second time i run show, dunno why i got all the value none

from sophy.

also i want to ensure that if env.add_database wont desctroy all the data in a exists store path?

Correct, add_database is not destructive.
