Hi All, I have a scenario where I track all the sales data for each day. My Object signature looks like this:
class SalesData(db.Model): sales_amount = db.FloatProperty() when = db.DateProperty(auto_now_add=True) item = db.StringProperty() the SalesData.sales_amount will be automatically incremented as and when an item of some name is sold. Now I need to print on a Graph which shows the items on y-axis, sales_amount-s on the axes plane, and the dates on the x-axis. I Used the graphy chart_api which makes the display part very easy; But then, I need to fetch the data accordingly. ** group by dates, items ** Can anyone guide me how I can get a list of different Items, grouped by date ? Thank you for all who answers this. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
