问题描述
我有一个如下所示的RABL模板
I have a RABL template as shown below
object @user
attributes :name
child :contacts do
# does not work
if contact.is_foo?
attributes :a1, :a2
else
attributes :a3, :a4
end
end
如何访问模板child
块中的Contact
对象?我需要在子实例上执行一些条件逻辑.
How do I access the Contact
object in the child
block of the template? I need to perform some conditional logic on the child instance.
推荐答案
您可以通过声明block参数来访问当前对象.
You can access the current object by declaring the block parameter.
object @user
attributes :name
child :contacts do |contact|
if contact.is_foo?
attributes :a1, :a2
else
attributes :a3, :a4
end
end
旧答案
我最终使用了root_object
方法,它会在给定的上下文中返回数据对象.
Old answer
I ended up using the root_object
method, which returns the data object in a given context.
object @user
attributes :name
child :contacts do
if root_object.is_foo?
attributes :a1, :a2
else
attributes :a3, :a4
end
end
