>From my study of the documentation, it seems to be the case that the state of "pending" refers to the set of instances that is the sum of both session.new and session.dirty. Is this understanding correct?
In addition, using session.add() will almost always lead to a new item in session.new, while using session.merge() will almost always lead to a new item in session.dirty. For example, if I have an instance named p. If I use session.add(p): >>>session.add(p) >>>session.new IdentitySet(([<__main__.P object at 0xb69fbc0c>]) >>>session.dirty IdentitySet([]) If I use session.merge(p): >>>session.merge(p) >>>session.new IdentitySet([]) >>>session.dirty IdentitySet(([<__main__.P object at 0xb69fbc0c>]) So, the conclusion is: session.add ==> a new item added to session.new session.merge ==> a new item added to session.dirty session.add + session.merge ==> "pending" Is my conclusion correct? -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
