请在控制器中考虑以下方法:
def get_navigation_from_session
respond_to do |format|
format.json { render json: session[:navigation]}
end
return session[:navigation]
end
我想要它做的是响应Ajax调用并发送导航哈希,如果它被要求它。如果没有,我只是希望它将哈希返回到需要它的ruby代码。这显然不起作用。如何修复上述方法来实现这一目标?
谢谢

# this is your action method, supposed to be called via your request cycle with rendering
def get_navigation_from_session
respond_to do |format|
format.json { render json: get_navigation_hash_from_session }
end
end
# a getter - maybe higher up in controller hiararchy
def get_navigation_hash_from_session
session[:navigation]
end
