Defines database backend library and database table and object relationships.

Example usage:
|
|
|
|
import database, db_mid
|
|
|
|
# get platform with id 7; will raise exception if no such platform.
|
|
p7 = database.Platforms[7]
|
|
|
|
# get platforms with friendly name "commodore 64"
|
|
p_c64 = database.Platforms.find(user_friendly_name="commodore 64")
|
|
|
|
# delete results of workunit with name "dead.wu", and email their users:
|
|
wu_dead = database.Workunits.find(name="dead.wu")[0]
|
|
results_dead = database.Results.find(wu=wu_dead)
|
|
for result in results_dead:
|
|
print "Removing from db:", result
|
|
os.system("echo oeps | mail %s" % result.host.user.email_addr)
|
|
result.remove()
|
|
|
|
# multiply the total_credit of each user by 17:
|
|
for user in database.Users.find():
|
|
user.total_credit *= 17
|
|
user.commit()
