Then let extract the usage of attr_accessor into a smaller example:
class TardisMotoForm
attr_accessor :user, :params
def save(attributes = {}, user = nil)
@user = user
@params = attributes
user.errors.empty?
end
end
Here we have three user
text:
:user
: define user
attribute of the class, which can be access from the outside world.
@user
: for assign user into attribute :user
as define in attr_accessor
.
user
: method params will assign to instance variable @user
.
For a class we can have these kinds of attribute:
attr_reader
attr_writer
attr_accessor
