just showing some syntax stuff

# I see this a lot, and it is perfectly OK to do this
def new_cat(name, color)
   cat = Cat.new
   cat.name = name
   cat.owner = self
   cat.color = color
   cat.save
end

# Here's another way to do that
# This does the same thing but doesn't need a local var
# returns true/false
def newer_cat(name, color)
  Cat.create do |cat|
    cat.name = name
    cat.owner = self
    cat.color = color
  end
end

# or make a bunch of them
# *note that this will fail on mass assignment unless you specify to ignore it
def create_cat_lady(*attrs)
  Cat.create(attrs) do |cat|
    cat.owner = self
  end
end

# creates two cats, returns true/false
create_cat_lady({name: 'meowmeow', color: 'brown'}, {name: 'curtis', color: 'orange'})

# And lastly, if you don't need/want to save the object yet
def new_cat_instance(name, color)
  Cat.new do |cat|
    cat.name = name
    cat.owner = self
    cat.color = agent_uuid
  end
end

# this returns the instance, so you don't need to create a var inside the method

my_new_cat = new_cat_instance('mittens', 'brown and white')
