3,052 PointsCreating and using more than 1 database dynamically using peewee
Hi,
This is what I want to do:
- I want to create three database
- Add data to this databases (making sure that data is added to correct database).
- Retrive data from these databases.
Here's what I've done so far.
from peewee import *
database_proxy = Proxy() # Create a proxy for our db.
class BaseModel(Model): class Meta: db = database_proxy # Use proxy for our DB.
class Overview(BaseModel): date = DateTimeField(unique=True) auto_total = CharField() .... ... ..
def initialize(loc): """ Initialising database based on the some condition""" if "Performance" in loc: db = SqliteDatabase('Performance.db', threadlocals=True) elif "Snapchat" in loc: db = SqliteDatabase('Snapchat.db', threadlocals=True) elif "Intelligence" in loc: db = SqliteDatabase('Intelligence.db', threadlocals=True) database_proxy.initialize(db) db.connect() db.create_tables([Overview], safe=True)
def add_data(test_date, time_duration, auto, manual, total): """ adding data to database""" try: Overview.create(date=test_date, auto_total=auto[1], auto_pass=auto[2], auto_fail=auto[3], .... ... .. print("New Row Added") except IntegrityError: update_results = Overview.get(date=test_date) update_results.auto_total = auto[1] update_results.auto_pass = auto[2] ..... .... ..
def get_rows(): cursor = Overview.select().order_by(Overview.date.desc()) print(cursor)
for test in cursor:
print()
I's able to create three data bases at run time. But I,m not sure
- How to add data to the correct database?
- How to retrieve data from the correct database?
Any suggestions will be really helpful.
Thanks Santosh
