缺少模板 Rails 版本：5.0.5

Question

我正在尝试在我的表单上恢复验证的错误消息（必须没有重复的成分）但我总是有一个我无法更正的 MISSING TEMPLATE，我知道这是一个路线问题，但我做到了不知道是哪一个。 我有 3 个模型，鸡尾酒成分和剂量，剂量链接鸡尾酒和成分

缺少带有 {:locale=>[:en]、:formats=>[:html] 的模板鸡尾酒/23， :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, ：咖啡，：jbuilder]}。搜索：* "/home/dezrt/code/Pseud0/rails-mister-cocktail/app/views"

这行render cocktail_path(@cocktail) 是错误的原因。 render 加载视图。所以render 的输入通常应该是文件名，在你的情况下show 是cocktails 的视图。将其更改为 render 'cocktails/show' 应该可以修复错误。

另外，您似乎对render 和redirect_to 感到困惑。我建议你阅读render vs redirect
