我的网站正在我的开发机器上运行，部署到 heroku 我在日志中得到了这个：

这是我的路线文件的一部分：

resources :hints do
    collection do
        get 'found_sentences'
    end
end

这是我的hints_controller.rb：

#encoding: utf-8
class HintsController < ApplicationController
    # GET /hints
    # GET /hints.json

    authorize_resource

    before_filter :authenticate_user!

    layout "application", :except => [:found_sentences]

    # GET /hints/find_sentences/
    def found_sentences
        #authorize! :find_sentences, @user, :message => 'Not authorized as an administrator.'

        @hints = Hint.where("sentence LIKE ? AND user_id =?", "%#{params[:word]}%", current_user.id) #.order("LENGTH(sentence) ASC").limit(5)

        render :layout => 'layouts/found_sentences'

        #respond_to do |format|
        #   format.html # find_sentences.html.erb
        #   format.json { render json: @hints }
        #end

    end

    def index
        #authorize! :index, @user, :message => 'Not authorized as an administrator.'

        #@hints = Hint.order(:created_at).reverse()
        @hints = Hint.find_all_by_user_id(current_user.id).reverse()
        #@hints = @current_user.hints

        respond_to do |format|
            format.html # index.html.erb
            format.json { render json: @hints }
        end
    end

    # GET /hints/1
    # GET /hints/1.json
    def show
        #authorize! :show, @user, :message => 'Not authorized as an administrator.'

        @hint = Hint.find(params[:id])
        #@hint = @current_user.hints.find(params[:id])


        respond_to do |format|
            format.html # show.html.erb
            format.json { render json: @hint }
        end
    end

    # GET /hints/new
    # GET /hints/new.json
    def new
        #authorize! :new, @user, :message => 'Not authorized as an administrator.'

        #@hint = Hint.new
        @hint = Hint.new(:user_id => @current_user_id)

        respond_to do |format|
            format.html # new.html.erb
            format.json { render json: @hint }
        end
    end

    # GET /hints/1/edit
    def edit
        #authorize! :edit, @user, :message => 'Not authorized as an administrator.'

        @hint = Hint.find(params[:id])
        #@hint = Hint.find(:user_id => @current_user_id)

        #todo shouldn't be able to edit other user's hints. for some reason the Lesson model responds to @current_user.lessons, but the Hint model doesn't respond to @current_user.hints

    end

    # POST /hints
    # POST /hints.json
    def create
        #authorize! :create, @user, :message => 'Not authorized as an administrator.'

        @hint = Hint.new(params[:hint])


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

    # PUT /hints/1
    # PUT /hints/1.json
    def update
        #authorize! :update, @user, :message => 'Not authorized as an administrator.'

        @hint = Hint.find(params[:id])

        respond_to do |format|
            if @hint.update_attributes(params[:hint])
                format.html { redirect_to @hint, notice: 'Hint was successfully updated.' }
                format.json { head :no_content }
            else
                format.html { render action: "edit" }
                format.json { render json: @hint.errors, status: :unprocessable_entity }
            end
        end
    end

    # DELETE /hints/1
    # DELETE /hints/1.json
    def destroy
        #authorize! :destroy, @user, :message => 'Not authorized as an administrator.'

        @hint = Hint.find(params[:id])
        @hint.destroy

        respond_to do |format|
            format.html { redirect_to hints_url }
            format.json { head :no_content }
        end
    end
end

我尝试删除这一行：render :layout => 'layouts/found_sentences'并取消注释：

    #respond_to do |format|
    #   format.html # find_sentences.html.erb
    #   format.json { render json: @hints }
    #end

但这没有用。接下来我应该尝试什么？

要求更新：

[~/rails_projects/blt]$ls app/views/{application,hints}
ls: app/views/application: No such file or directory
app/views/hints:
_form.html.erb           edit.html.erb            found_sentences.html.erb index.html.erb           new.html.erb             show.html.erb

问题出在index行动上，而不是在find_sentences。添加index.html.erb到app/views/hints.

这不是问题所在。

请阅读完整的聊天记录，了解我们如何找到实际问题。

用户使用的是 Mac，其文件系统不区分大小写。创建模板目录时，Hints ( app/views/Hints)使用大写 H。Heroku 使用 linux 和区分大小写的文件系统，这会导致错误。
