I have a method 'calc_price' that was working previously, and still works in console, but is now giving me the following error in a browser:
NoMethodError in Quotes#index
undefined method `+' for nil:NilClass
18: Price: $<%= f.calc_price %><br />
app/models/quote.rb:33:in `block in calc_price'

The fact that it still works in console is confusing to me, especially since I didn't change the method at all for it to break. The method:
def calc_price
self.items.each do |item|
pr = if item.amount < 10
item.product.pricerange0
elsif item.amount < 25
item.product.pricerange1
elsif item.amount < 50
item.product.pricerange2
elsif item.amount < 100
item.product.pricerange3
elsif item.amount < 250
item.product.pricerange4
elsif item.amount < 500
item.product.pricerange5
end
screens = 0
sd = item.shirtdesigns.count
pd = item.pantdesigns.count
screens = (sd+pd)
screenprice = (screens*25)
inkprice = ((item.inkcolors-1)*0.5)
newprice = ((pr+inkprice)*item.amount+screenprice)
item.price = newprice
item.save
end
newprice = self.items.sum('price')
self.price = newprice
self.save
return self.price
end
quote controller
def index
@quote = Quote.find(:all)
@myquotes = Quote.find(:all, :conditions => { :user_email => current_user.email })
end
I tried adding screenprice = 0, newprice = 0 and inkprice = 0 to see if that would make a difference but it did not.
If it still works in console does that mean maybe its not the method itself that is broken?
Any help would be greatly appreciated! Thanks
pr
is most likely nil. An item with an amount greater than 500 would result in pr
being nil in the code above.
