Hi Bill, the issue was that the variables being passed to the class
method from rake were assigned to var=0 so that's why I was getting that
error. I had forgotten to check my rake file and once I went back and
retraced my steps I realized I hadn't passed the type of variable to the
class method (array in this case).
Further,
I have the method working like this now:
def calculate_tsos(model, datavar, teamvar, valvar)
var = model.compiled_this_week.find(:all, :order => :team_id)
var.each_with_index do |rows, i|
teamvar[i] = rows.team.id
valvar[i] = rows.__send__(datavar)
puts "#{model} [ Row #{i} | Team ID = #{teamvar[i]} | Team =
#{rows.team.name} | #{datavar} = #{valvar[i]}"
end
end
As a rake file test, I tried:
to_team_id = []
to_value = []
update_tsos_offense = TsosOffense.new
update_tsos_offense.calculate_tsos(TotalOffense, "ydspgm", to_team_id,
to_value)
puts "From Rake to_team_id = #{to_team_id[1]} and to_value =
#{to_value[1]}"
And receive:
>From Rake to_team_id = 2 and to_value = 484.85
.. which is correct so it looks like the values were assigned to the
arrays and that I should be able to use them, once I finish manipulating
them (performing calculations).
But, again, is there a better way to do this? Should I not perform
calculations within the class method on that model? Or, should I keep
things neat and tidy by performing calculations in a ruby file within my
libs directory?
I just want to get better at what I'm doing...
