9,945 PointsCall the title method on the name instance. Syntax error?
I was finally able to fix this by typing name.title instead of Name.title. I thought you were supposed to use capitalization when calling a Class name. Is this just a "best practice" and not totally necessary?
class Name
def first_name
"Metal"
end
def initialize(title)
@title = title
end
def last_name
"Robot"
end
def title
@title
end
end
name = Name.new("Kyle")
Name.title

Treehouse TeacherThe reason calling Name.title
doesn't work is because that attempts to call a method named title
on the Name
class itself, which doesn't exist. Instead, you want to create an instance of the Name
class (a Name
object), and call the title
method on that instance (which does exist).
The point of confusion seems to be that we've asked you to use a variable name that's just a lower-case version of the class name. They might look the same to you, but since Ruby is case-sensitive, you might as well have used a totally different name for the variable, and it would have the same effect:
qyzzyg = Name.new("Kyle")
qyzzyg.title
That would work just as well in Ruby. (Although it might not pass the challenge, since it asks you to store it in a variable named name
.)
