我想在每个渲染的视图中出现几个视图,但是没有重复代码或违反规范,我似乎无法找到实现这一目标的方法. 这是我当前的代码,在每个视图中调用： def ImOnABoat::Views def layout html do head
这是我当前的代码,在每个视图中调用：
def ImOnABoat::Views
def layout
html do
head do title "Petstore" end
body do yield end
end
end
def navigation
p "Welcome to our tiny petstore!"
end
def poodle
navigation # Have to duplicate this in every view
p "We have a poodle!"
end
def fluffy_bunny
navigation # Have to duplicate this in every view
p "Come see-- OH CRAP IT'S A VELOCIRAPTOR!"
end
end
我也可以通过允许公共块在体外渲染来使其工作,但这违反了规范,并且最终可能会破坏一些刮刀脚本.
def layout def head do title "Petstore" end nav # This is not inside <body>! def body do yield end end请记住,这是纯Ruby,因此您只需在布局中调用导航方法：
module ImOnABoat::Views
def layout
html do
head { title "Petstore" }
body do
navigation
yield
end
end
end
def navigation
p "Welcome to our tiny petstore!"
end
def poodle
p "We have a poodle!"
end
def fluffy_bunny
p "Come see-- OH CRAP IT'S A VELOCIRAPTOR!"
end
end
