Question

我知道我正在以某种方式破坏Rails惯例导致错误，但我无法弄清楚是什么......

# controller
def membership
   @user = User.new(user_type:"member")
end
def membership_create
   @user = User.find(params[:id])
   ...
end

# routes
match '/membership/create.:id', to: "users#membership_create", via: :post, as: "create_member"

# view
# have tried the following based on various other answers, doesn't work
<%= form_for @user, :url => create_member_path(@user), method: :post do |f| %>
<%= form_for @user, :url => create_member_path(@user) do |f| %>

始终收到错误消息：No route matches {:action=>"membership_create", :controller=>"users", :id=>nil} missing required keys: [:id]

为什么不/membership/create/:id而不是/membership/create.:id？

但是，您只是从您的会员方法构建新用户：

def membership
  @user = User.new(user_type:"member")
end

此用户还没有id。因此，当您将其传递到表单的路径时：

<%= form_for @user, :url => create_member_path(@user) do |f| %>

id为nil。

但是，您的membership_create需要id？ - （在路线中配置）请记住，此时此值为零。除非你奇迹般地在循环中的某个地方包含id，这是我看不到的，或者这两种方法并没有像我想的那样直接相关。

Rails形成自定义路径＆amp;丢失所需的ID密钥
