[google-appengine] Type for any types of proprety?
Hello. In datastore, I want to create a misc "table" to store dynamic properties which is not in the defined model. For example class Account_base(db.Model): account_id = db.StringProperty() password = db.StringProperty() class Account_extension(db.Model): base_key = db.StringProperty() # refer to base's key prop_name = db.StringProperty() # property name prop_value = db.StringProperty() # property value - this is where I want to want make it dymanic typed, often TextProperty or IntegerProperty!! What should I define the type of Account_extension.prop_value, so that I can possibly assign it any type of values? Many thanks.

[google-appengine] When will appcfg.py be able to download/check out?
This is not a usual case, but people at times may still need it. I have two machines, one in office and one at home, working on the same GAE project. My usual practice to synchronize these 2 environments is to copy the files over my USB drive. As you can see this is very traditional way. I once came across the idea to use a SVN server to sync, but now I think it may be the best that GAE provides such features for us. When we do `appcfy.py update`, it is really a update or check-in. Why not just add check-out ?

[google-appengine] Re: Eating one's own dog food
Hi there. I did not pay anything for any services, inc. gmail, google docs, gmaps, to Google.:-) She got big pays by someone else. For GAE as hosting provider, i agreed that for exceeding quota it may be more expensive than other providers. However, different people have different ways to calcuate the cost. As for me as an individual, I am not thinking to pay for it at this moment. :-p Juguang On Fri, Jul 17, 2009 at 10:38 AM, GenghisOne wrote: > > Hi Juguang > > Your words provide a nice counter-balance to those who are not so > happy with App Engine.
