Question

我与User和SecurityBadge模型一对一关联。我有一个问题，我无法渲染我的views/security_badges/_form，因为它生成了复数user_security_badges_path而不是单数user_security_badge_path

当我访问此链接时：

localhost:3000/users/1/security_badge/new

我在development.log文件中收到了这个消息：

ActionView::Template::Error (undefined method `user_security_badges_path' for #<#<Class:0x00007f888fb456d0>:0x00007f888fccff00>
Did you mean?  user_security_badge_path
               user_security_badge_url):
    1: <%= form_with(model: [@user, security_badge], local: true) do |form| %>
    2:   <% if security_badge.errors.any? %>
    3:     <div id="error_explanation">
    4:       <h2><%= pluralize(security_badge.errors.count, "error") %> prohibited this security badge from being saved:</h2>

这是在我的_form中： 我很确定问题出在model: [@user, security_badge] 上，它生成的是复数路径而不是单数路径。但是我不知道该如何解决。

<%= form_with(model: [@user, security_badge], local: true) do |form| %>
  <% if security_badge.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(security_badge.errors.count, "error") %> prohibited this security_badge from being saved:</h2>

      <ul>
      <% security_badge.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= form.label :name %>
    <%= form.text_field :name, autofocus:true, class: "form-control" %>
  </div>

  <br>
  <div class="row float-right">
    <div class="col-md-12 actions">
        <%= link_to "Cancel", user_path(@security_badge.user), id: 'cancel', class: 'btn btn-outline-secondary' %>
        <%= form.submit "Submit", id: "submit", class: 'btn btn-success' %>
    </div>
  </div>

<% end %>

新视图模板：

<%= render 'form', security_badge: @security_badge %>

用户模型：

class User < ApplicationRecord
  has_one :security_badge, dependent: :destroy
end

SecurityBadge模型：

class SecurityBadge < ApplicationRecord    
  belongs_to :user    
end

我的路线：

  resources :users do
    resource :security_badge
  end

我的某些控制器security_badges_controller：

  before_action :set_user, only: [:index, :show, :new, :edit, :create, :update]
  before_action :set_security_badge, only: [:show, :edit, :update, :destroy]

  def new
    @security_badge = @user.build_security_badge
  end

  def edit
  end

  def create
    @security_badge = @user.security_badge.new(security_badge_params)

    respond_to do |format|
      if @security_badge.save
        format.html { redirect_to user_security_badge_path(@security_badge.user), notice: 'Security badge was successfully created.' }
      else
        format.html { render :new }
      end
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_user
      @user = User.find(params[:user_id])
    end

    def set_security_badge
      @security_badge = SecurityBadge.find(params[:id])
    end

更新

我通过使用url显式传递单数路径来使它起作用，但是对于非复数的嵌套路由，建议这样做吗？有没有一种方法可以使form_with与嵌套的奇异路线一起使用，或者这是做到这一点的方法？

<%= form_with(model: security_badge, url: user_security_badge_path(@user), local: true) do |form| %>
