form_with 出现错误（未定义的方法）

Question

我有_form.html.erb。在代码的第一行，它抛出了这个错误：

#ActionView::Base:0x00000000229750 的未定义方法“assessments_path” 你的意思？ asset_path

几点：

在路由中 'poweruser' 是一个命名空间
在模型中 assessment.rb 是不是文件夹 poweruser（因为我计划将它用于任何人都可以访问的其他页面，而不仅仅是 powerusers）。
知道我遗漏了什么吗？

代码如下：

<%= form_with(model: [@assessment], local: true) do |form| %>
  <%= render "shared/error_messages", resource: form.object %>

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

<% end %>

这是控制器

module Powerusers
  class AssessmentsController < ApplicationController
    before_action :authenticate_user!
    # before_action :set_assessment
    # before_action :set_assessment, only: [:set_assessment, :show, :edit, :update, :destroy]
    # Overwrite any of the RESTful controller actions to implement custom behavior
    # For example, you may want to send an email after a foo is updated.
    #
    # def update
    #   super
    #   send_foo_updated_email(requested_resource)
    # end

    def index
        @pagy, @assessments = pagy(Assessment.sort_by_params(params[:sort], sort_direction))
        # We explicitly load the records to avoid triggering multiple DB calls in the views when checking if records exist and iterating over them.
        # Calling @assessments.any? in the view will use the loaded records to check existence instead of making an extra DB call.
    @assessments.load
    end

    # GET /assessments/new
    def new
      @assessment = Assessment.new
      @assessment.assessment_sections.new
    end

这里是 assessment.rb（不是不是在子文件夹 poweruser 中）

class Assessment < ApplicationRecord
  belongs_to :company
  has_many :assessment_sections, inverse_of: :assessment
  has_many :questions, through: :assessment_sections

  accepts_nested_attributes_for :assessment_sections, reject_if: :all_blank,
                                allow_destroy: true
  accepts_nested_attributes_for :questions, reject_if: :all_blank,
                                allow_destroy: true
end

这是路线

  # PowerUser
  authenticated :user, lambda { |u| u.admin? } do
    namespace :powerusers do
      resources :assessments do
        resources :assessment_sections do
          resources :questions
        end
      end
    end
 end

Answer 1

由于路由中有命名空间，因此需要使用 form_with

指定

<%= form_with(model: [:powerusers, @assessment], local: true) do |form| %>

form_with 出现错误（未定义的方法）

Getting error (undefined method) for form_with
