Google App Engine: how to tell sort location for a user value?
You could get the count of number of entities that have total_value less than or equal to the current users total_value.
You could use the count() method to do so (on a Query object).
In my Main model I have a total_value and I sort with this value. When a user enters a value I wish to tell the user the order of his total_value. How do I do this?
In other words, if total_values in database are 5,8,10,25 and a user enters a total_value of 15 how do I tell him that he will be in the 4th place? 
Thanks!
