Ruby on rails 4 积垢操作“；删除“；don'；t在我的第一个RubyonRails项目中工作

我在我的第一个项目中实现了crud操作“delete”，但是系统将该命令作为一个“get”，没有错误

这是控制器：

class MoviesController < ApplicationController

def index
    @movies = Movie.all      
end
#GET /movies/:id
def show
    id = params[:id]
    @movie = Movie.find(id)
    #render plain: 'show'+params[:id]
end
#POST /movies/
# skip_before_action :verify_autenticity_token:
def create
    @movie = Movie.create!(params[:movie].permit(:title, :rating, :description, :realease_date))
    flash[:notice] = "#{@movie.title} was successfully created."
    redirect_to movies_path
end

#new
def new
end

def edit
  id = params[:id]
    @movie = Movie.find(id)
end

def update
  id = params[:id]
  @movie = Movie.find(id)
  if @movie.update_attributes!(params[:movie].permit(:title,:rating,:realease_date))   
   flash[:notice] = "#{@movie.title} has been edited."
   redirect_to movies_path
  end
end

def destroy
  id = params[:id]
  @movie = Movie.find(id)
  @movie.destroy
  flash[:notice] = "#{@movie.title} has been deleted."
  redirect_to movies_path
end


end

命令“rake routes”的结果：

---

如果看不到相应的路线，很难说到底发生了什么。您可以尝试运行

rake routes

，查看可用的路由

根据控制器中的注释，我猜您可能必须执行类似于将路径

链接到“Delete”、movies\u路径（id:@movie.id）、method:：Delete

（删除）多元化的操作，但只有在资源路由配置错误的情况下才能解决问题

---

为了使链接按您所配置的方式工作，您的路由文件必须包含

资源：电影

，或者一个特殊配置的路由来映射到删除操作。

我有更新文件“routes.rb”和命令“rake routes”的答案，可以帮您找到答案吗？请尝试

{link_to'delete'，“/movie/{@movie id}”，：method=>：delete}

。如果这样做有效，那么route helper将出现问题。另外，您在该页面上有JavaScript吗？您可能在点击链接时触发了一个

GET

请求。我有更新文件“routes.rb”和命令“rake routes”的答案，可以帮助您找到答案吗？请尝试

end
