Treehouse TeacherI tried to run your code as it is right now and got this error: NoMethodError: undefined method 'value_at'
. This is because there's a typo in the method name; it should be values_at
.
Here's the previous wording on the second challenge task:
Using the
values_at
method, create an array calledgrocery_list
with the value of thegrocery_item
hash at the"item"
key.
Admittedly, this is a little unclear. I've changed it to this:
Use the
values_at
method on thegrocery_item
hash to get an array consisting of a single value: the value of the"item"
key. Store the returned array in a variable namedgrocery_list
.
So you're close - you just need to fix the method name and then assign the return value to a grocery_list
variable.

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
if grocery_item.has_value? ("Bread")
grocery_item.store ("food" , true)
end
grocery_list = grocery_item.values_at("item")
