I have the following in a model class:
class Game < ActiveRecord::Base
has_many :player_stats
has_many :players, :through => :player_stats
def visitor_stats
stats = []
player_stats.each do |stat|
stats << stat if stat.player.team.team_code ==
self.visiting_team_code
end
stats
end
def home_stats
stats = []
player_stats.each do |stat|
stats << stat if stat.player.team.team_code ==
self.home_team_code
end
stats
end
end
I understand that this isn't the most efficient or elegant way to do
things. I gleaned this most recently from the posting at (see his
Case 3):
http://www.therailsway.com/tags/has_many
So, I would like to do something like the following, but I'm having a
problem with the conditions:
has_many :visitor_stats, :class_name=>"PlayerStat", :conditions=>
<what???>
the condition here should be something matching "player.team.team_code
== self.visiting_team_code" in the code I have now.
has_many :home_stats, :class_name=>"PlayerStat", :conditions=>
<what???>
and here it should be something matching "player.team.team_code ==
self.home_team_code" in the existing code.
The conditions specified need to be something that could go in a SQL
statement, right? How would I make the conditions work thru the
associations of a PlayerStat belonging to a Player belonging to a Team
which has a team_code. And matching it to this Game's
visiting_team_code or home_team_code
