Rails：使用关联时，不会在模型上调用method_missing
||
我当前的代码：
class Product < ActiveRecord::Base
belongs_to :category
end
class Category < ActiveRecord::Base
def method_missing name
true
end
end
Category.new.ex_undefined_method #=> true
Product.last.category.ex_undefined_method #=> NoMethodError: undefined method `ex_undefined_method\' for #<ActiveRecord::Associations::BelongsToAssociation:0xc4cd52c>
private
def method_missing(method, *args)
if load_target
if @target.respond_to?(method)
if block_given?
@target.send(method, *args) { |*block_args| yield(*block_args) }
else
@target.send(method, *args)
end
else
super
end
end
end
Product.last.category.ex_undefined_method #=> true
没有找到相关结果

：class Category < ActiveRecord::Base def method_missing(name, *args, &block) if name =~ /^handleable/ \"Handled\" else super end end def respond_to?(name) if name =~ /^handleable/ true else super end end end，则应该始终更新-您已经更改了班级的界面，因此需要确保每个人都知道它。看这里。俺呵誓放胳
def respond_to?(name,include_private = false) if name =~ /^handleable/ true else super end end芜任亮蜡
if @target.respond_to?(method) if block_given? @target.send(method, *args) { |*block_args| yield(*block_args) } else @target.send(method, *args) end else super endif block_given? @target.send(method, *args) { |*block_args| yield(*block_args) } else @target.send(method, *args) end
