我的观点：

class FriendsController < ApplicationController

  def index
    @friends = Friend.all
end

  def show
    @friend = Friend.find(params[:id])

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

  def new
    @friend = Friend.new

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

  def edit
    @friend = Friend.find(params[:id])
  end


  def create
    @friend = Friend.new(params[:friend]
  end

  def update
    @friend = Friend.find(params[:id])

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



  def destroy
    @friend = Friend.find(params[:id])
    @friend.destroy

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

Answer 1

在更新结束时，您似乎错过了一个结尾：

@friend = Friend.find(params[:id])
  respond_to do |format|
    if @friend.update_attributes(params[:friend])
      format.html { redirect_to @friend, notice: 'Friend was successfully updated.' }
      format.json { head :no_content }
    else
      format.html { render action: "edit" }
      format.json { render json: @friend.errors, status: :unprocessable_entity }
    end
  end
end #add this one :)

你的创作在结尾处缺少一个结束括号：

def create
  @friend = Friend.new(params[:friend])
end

Answer 2

您的update方法遗失了end。

Answer 3

您的更新方法缺少结束

rails语法错误..意外结束
