ArgumentError，创建操作中参数数量错误（0 为 2），适用于 Heroku，但不适用于本地服务器

发布于 2024-12-23 04:26:24 字数 8326 浏览 1 评论 0原文

我最近有一个由第三方为我开发的 RoR 应用程序，现在我要自己添加我想要的未来功能。它可以在 Heroku 上运行，但是当我尝试在 localhost:3000 上运行它时，出现 ArgumentError。我没有更改任何代码，我只是从 github 中提取它并尝试在本地开发服务器上运行它以实现新的更改。我已经向他们询问过这个问题，但他们不确定原因，所以这里...

我们正在运行 ruby​​ 1.9.2，rails 3.0.7

每当我尝试在我的网站上保存项目时，或者每当在对象上调用 .save，我得到一个 ArgumentError，参数数量错误（2 代表 0）。

projects_controller 中的代码，第24 行是if 语句

def create
    @project = Project.new(params[:project])
    @project.memberships.build(:user_id => current_profile.id, :pending => false)

    if @project.save
      redirect_to destination, :notice => 'Project was successfully created.'
    else
      build_project_associations_for_nested_forms
      render :action => 'new'
    end
   end

我对此有点陌生，所以我不太确定还需要什么来确定问题。

原文

I recently had a RoR application developed for me by a third party and now I'm on my own to add future features that I want. It works on Heroku, but when I try to run it on localhost:3000, I get an ArgumentError. I have not changed any of the code, I just pulled it from github and tried to run it on a local development server to implement new changes. I've asked them about this problem, but they are not sure of the cause, so here goes...

We're running ruby 1.9.2, rails 3.0.7

Whenever I try to save a project on my site, or whenever .save is called on an object, I get an ArgumentError, wrong number of arguments (2 for 0).

the code from projects_controller, line 24 is the if statement

def create
    @project = Project.new(params[:project])
    @project.memberships.build(:user_id => current_profile.id, :pending => false)

    if @project.save
      redirect_to destination, :notice => 'Project was successfully created.'
    else
      build_project_associations_for_nested_forms
      render :action => 'new'
    end
   end

I'm a bit new at this, so I'm not quite sure what else is needed to determine the problem.

您是否尝试过运行 WEBrick 以外的其他程序（假设您正在使用它）？尝试安装 Thin (gem install Thin) 并查看问题是否仍然存在。

Have you tried running something other than WEBrick (assuming you're using that)? Try installing Thin (gem install thin) and see if the problem persists.

确保您已获得所有必需的 gem，运行捆绑安装：

bundle install

重新启动应用程序，希望这会有所帮助。

Make sure that you have got all the required gem, run bundle install:

bundle install

Restart the app, hopefully that helps.
