铁路:如果模型已经存在,如何操作“铁路产生聋子”?
原标题:Rails: How to run `rails generate scaffold` when the model already exists?

我向铁路提供新东西,因此,我目前的项目处于一个ir状态。

我产生的第一个事情是“Movie”模式。 随后,我开始更详细地界定这一定义,并增加了一些方法等。

我现在认识到,我本应该以<条码>生成铁路,以发现像行车、观点、控制器等东西。

我试图打上手脚,但我发现一个错误,说已经存在同样的移民档案。

What s the best way for me to create scaffolding for my "Movie" now? (using rails 3)

最佳回答

<TL;DR:rails g scafraft_ Controller <name>

Even though you already have a model, you can still generate the necessary controller and migration files by using the rails generate option. If you run rails generate -h you can see all of the options available to you.

Rails:
  controller
  generator
  helper
  integration_test
  mailer
  migration
  model
  observer
  performance_test
  plugin
  resource
  scaffold
  scaffold_controller
  session_migration
  stylesheets

如果你想为你的模型生成一个控制器的手法,请见scafridge_ Controller<>。 为明确起见,本文件仅作以下描述:

Stubs out a scaffolded controller and its views. Pass the model name, either CamelCased or under_scored, and a list of views as arguments. The controller name is retrieved as a pluralized version of the model name.

To create a controller within a module, specify the model name as a path like parent_module/controller_name .

This generates a controller class in app/controllers and invokes helper, template engine and test framework generators.

为了创造你们的资源,你利用<资源代码>(<>>>>>)的生成器,并创造出一种移民点,你还可以看到<条码> 移民<>/代码>的生成器(见所有这种疯狂的格局)。 这些办法为建立资源提供了选择。 或者,你只能操作<条码>铁路,产生条码<>/条码>和<条码>。 查阅现有档案的选择:

我建议花费一些时间研究发电机内的各种选择。 他们说,我觉得书本中记录得很好,但又很 hand。

问题回答

由<代码>Lee Jarvis<>/code>作出大答复,这只是指挥,例如,我们已经有了一个称为用户的模式:

rails g scaffold_controller User

For the ones starting a rails app with existing database there is a cool gem called schema_to_scaffold to generate a scaffold script. it outputs:

<条码> 铁路网球用户名称:显示名称:显示日期: 电子邮件:string 加密-密码:string

页: 1 核对表

This command should do the trick:

$ rails g scaffold movie --skip

您可以使用<条码>条码<>条码/代码>,并记住通过该模型的<条码>attributes,或者没有属性将产生笔记。

rails g scaffold_controller User name email
# or
rails g scaffold_controller User name:string email:string

这一指挥将产生以下档案:

create  app/controllers/users_controller.rb
invoke  haml
create    app/views/users
create    app/views/users/index.html.haml
create    app/views/users/edit.html.haml
create    app/views/users/show.html.haml
create    app/views/users/new.html.haml
create    app/views/users/_form.html.haml
invoke  test_unit
create    test/controllers/users_controller_test.rb
invoke  helper
create    app/helpers/users_helper.rb
invoke    test_unit
invoke  jbuilder
create    app/views/users/index.json.jbuilder
create    app/views/users/show.json.jbuilder

我在开展<<6>Rails 6的工作时面临这一挑战。 页: 1

我已经有了一些模型,我需要为装饰控制器生成,并在 控制器 params上添加>>><>>>。

www.un.org/Depts/DGACM/index_spanish.htm 这里我是如何做的。

我使用了<条码>铁路生成双手——控制器,以便做到这一点。

我只掌握以下指挥:

rails generate scaffold_controller School name:string logo:json motto:text address:text

rails generate scaffold_controller Program name:string logo:json school:references

这产生了corresponding controllers for the models,并在上,包括foreign key等。

create  app/controllers/schools_controller.rb
invoke  test_unit
create    test/controllers/schools_controller_test.rb

create  app/controllers/programs_controller.rb
invoke  test_unit
create    test/controllers/programs_controller_test.rb

所有这一切都是如此。

www.un.org/Depts/DGACM/index_spanish.htm 我希望这一帮助能够达到
