    I've got a 2-dimensional array like this (it represents a timetable): http://www.shrani.si/f/28/L6/37YvFye/timetable.png Orange cells are lectures and whites are free time. How could I calculate number of free hours between lectures in the same day? (columns are days and rows are hours) For example, in this table the result should be: 2 for first column 0 for second colum -- The function returns 2 (because 2+0=2)

    - by Misha Moroshko
    I would like to validate that customer_price >= my_price. I tried the following: class Product < ActiveRecord::Base attr_accessor :my_price validates_numericality_of :customer_price, :greater_than_or_equal_to => my_price ... end (customer_price is a column in the Products table in the database, while my_price isn't.) Here is the result: NameError in ProductsController#index undefined local variable or method `my_price' for #<Class:0x313b648> What is the right way to do this in Rails 3 ?

  • Chain of Responsibility Pattern: is it a good practice to have interdependent handlers?

    - by wei
    I have this scenario: I have a chain of query handlers, the first is to query the cache, if the cache can't answer it or the answer is stale, then hit a database, if it can't find the answer or the answer is stale again, then query a remote web service. But I am not sure if this is the right way to use this pattern, since the work flow is pretty much fixed, and the cache and database handlers depend on the next step's return result to refresh its records.

  • Should I worry about running out of HierarchyIDs?

    - by Bruno Martinez
    When you ask for a new HierarchyID between two others, the result gets progressively longer. For example, between 2/5.6 and 2/5.7 there's only 2/5.6.1 and other 4 component paths. The HierarchyID data type is limited to 800 some bytes, so you can't repeat this forever. Then again, integer types are also limited, but it isn't a problem in practice. Should I periodically defragment my table so that height doesn't grow unbounded?
