I would like to log user actions whenever user logs in/out and adds, edits, deletes objects in my site models in flask. Which is the best way to do this? Also I would like to show the old data and the new modified data, which happens using wtfforms. I am using flask and Flask-SQLAlchemy. I want something similar to what Django framework offers in the ‘History‘ hlink for the associated objects.
Use Signals. Take a look at this
Using signals, you can keep track of any actions such as adds/edits etc. as needed. All you have to do is
from blinker import Namespace my_signals = Namespace() def add_user(): # add user code here user_added = my_signals.signal('user-added')
