Question

我有以下模型view。以下控制器Admin::ViewsController包含以下代码：

class Admin::ViewsController < ApplicationController
    before_action :set_admin_view, only: [:show, :edit, :update, :destroy]

    # GET /admin/views
    # GET /admin/views.json
    def index
        @views = View.all
    end

    # GET /admin/views/1
    # GET /admin/views/1.json
    def show
        filter_requests = FilterRequests.new(params)
        @requests = filter_requests.determine_what_to_do
        respond_to do |format|
            format.js           
            format.html
        end
    end

    # GET /admin/views/new
    def new
        @view = View.new
    end

    # GET /admin/views/1/edit
    def edit
    end

    # POST /admin/views
    # POST /admin/views.json
    def create
        @view = View.new(admin_view_params)

        respond_to do |format|
            if @view.save
                format.html { redirect_to @view, notice: 'View was successfully created.' }
                format.json { render action: 'show', status: :created, location: @view }
            else
                format.html { render action: 'new' }
                format.json { render json: @view.errors, status: :unprocessable_entity }
            end
        end
    end

    # PATCH/PUT /admin/views/1
    # PATCH/PUT /admin/views/1.json
    def update
        respond_to do |format|
            if @view.update(admin_view_params)
                format.html { redirect_to @view, notice: 'View was successfully updated.' }
                format.json { head :no_content }
            else
                format.html { render action: 'edit' }
                format.json { render json: @view.errors, status: :unprocessable_entity }
            end
        end
    end

    # DELETE /admin/views/1
    # DELETE /admin/views/1.json
    def destroy
        @view.destroy
        respond_to do |format|
            format.html { redirect_to admin_views_url }
            format.json { head :no_content }
        end
    end

    private
    # Use callbacks to share common setup or constraints between actions.
    def set_admin_view
        @view = View.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def admin_view_params
        params[:admin_view]
    end
end

uninitialized constant Admin::ViewsController::View是我在set_admin_view代码中遇到的错误。这是以下路线：

namespace :admin do
    scope :requests do
         resources :views
    end
end

为什么我会遇到这个问题？

如果你的viewmodel没有命名空间trip>

@view = ::View.find(params[:id])
