Hey all,
I'm looking at a piece of code developed by an experienced Rails
developer:
def create
@user = User.authenticate!(params[:email], params[:password])
@deployment = Deployment.find_by_name(params[:deployment_name])
end
In that third line, he calls a class method find_by_name on the
Deployment class. So naturally I look at Deployment.rb where the class
is initialized. But there is no find_by_name method. What I see is this:
validates_presence_of :name
def self.get(name)
find_by_name!(name)
end
So why does this not return an undefined method error? There's no setter
or getter (attr_accessor) for find_by_name so it has no definition
anywhere. Second point is find_by_name! is not declared anywhere either
so we pass the name local variable into it, but it's not defined
anywhere. Anyone understand what's going on here? Thanks for response.
