Check - It Works!

I figured it out. I have attributes in my Stat database table that the user doesn't provide input for. The value, for the hidden attributes, is gotten from the other attributes that the user does provide input for.

What I did:

In the Model:

before_validation :cache_virtual_columns

def total_points

((twopfgm * 2)+(threepfgm * 3)+(ftm * 1))

end

def field_goal_percent

sprintf("%0.3f", ((twopfgm+threepfgm)/(twopfga+threepfga.to_f)))

end

private

def cache_virtual_columns

self.total_points = total_points

self.field_goal_percent = field_goal_percent

end

In the Form:

%= f.hidden_field :total_points

%= f.hidden_field :field_goal_percent

When a new Stat record is created, it checks the Model and before doing validations does the cache_virtual_columns method. cache_virtual_columns has the total_points and field_goal_percent DB columns equal the value in their method. This updates the Stat record to contain values for each attribute.
