I'm stuck on this code challenge where we check the contents of the hash to see if they include a value called "Bread". If it does contain the value (it does) we are to add a new key "food" and set its value to "true". I keep getting errors with this, the most current error you see below is ArgumentError: 1 for 2. I tried an if statement and no dice. Any suggestions? I feel like this should be relatively straightforward. Thanks!
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
grocery_item.has_value?("Bread")
grocery_item.store( "food" => "true" )

5,784 PointsFound the answer in a forum, guess I didn't look hard enough! I tried an if statement before but didn't include the new key and value pair within the if statement. Here's the correct code:
if grocery_item.has_value?("Bread") grocery_item.store("food", true) end
Thanks for your responses!

Add to a hash:
hash[:key] = value
So you want:
grocery_item[:food] = true

5,784 PointsHi Charles, Thanks for your response! I just tried it and got the error message: "The key 'food' was not found within the hash."

7,575 PointsSorry, possibly need quotes around true. Couldn't remember if it was formatted that way or not since I was using a Boolean.
Heather Stone
5,784 PointsYep, I tried it both ways and no dice.

2,707 PointsThose codes do the same? Why the second throws me error?
if grocery_item.has_value?("Bread")
grocery_item.store("food", true)
end
if grocery_item.has_value?("Bread")
grocery_item[:food] = true
end

Based on that, I would say the syntax you have above is wrong, and should be:
grocery_item.store(:food, "true")
