I had to create both a name method and a find_by_name method. A bit hackish
but it works.
Here's everything I tried:
1) Just add a name field
fields do
name :string
end
works but the model doesn't make sense. It really doesn't have a name and
generating one seems problematic.
2) Have a path field but declare that to be the name. I thought this would
work.
fields do
path :string, :name => true
end
=> undefined method `name' for #<Clip:0xb60de5c4>
3) As suggested, define a name method.
fields do
path :string
end
def name
path
end
=> undefined method `find_by_name' for #<Class:0xb63d1b50>
4) Stub out both name and find_by_name
fields do
path :string
end
def name
path
end
def self.find_by_name(*args)
find_by_path(args)
end
Works!
I'd love to hear if there's a better way of doing this. Thanks kevinp.
