如何在Rails/Ruby中爲多個函數返回一個函數？

Question

以下只呈現最後部分行：

def default_sidebars 
    render :partial => 'shared/sidebars/box1' 
    render :partial => 'shared/sidebars/box2' 
    render :partial => 'shared/sidebars/box3' 
    render :partial => 'shared/sidebars/box4' 
end 

我怎麼能得到它使所有行？

Answer 1

def default_sidebars 
    res = render :partial => 'shared/sidebars/box1' 
    res += render :partial => 'shared/sidebars/box2' 
    res += render :partial => 'shared/sidebars/box3' 
    res += render :partial => 'shared/sidebars/box4' 
end
