Question

我现在举出属于其他应用模式的铁路模型,现在要提供电解表,以便分别更新相关物体的记录,这令人感到非常困惑。

下面是一类样本,用以分析我想要达到的目标:

     class Booking < ActiveRecord::Base` 
          belongs_to :user
          belongs_to :department
          belongs_to :invoice, :class_name => "Department"

     end
  `

之后,还试图提供假装。我不熟悉黑帮派,似乎很少有涉及该案的文件。

= form_for :booking, :url => booking_path(@booking), :html => { :method => :put } do |form|
  %ul
    - @booking.errors.full_messages.each do |msg|
      %li= msg

      = label :booking, :status
      = form.text_field :status

      - form.fields_for :user do |user_form| 

      = user_form.label :user, :fullname
      = user_form.text_field :fullname

      = form.submit "Update this booking"

感谢你们的答复。

羞耻是tation。铁路助手的实际使用根本不改变。当你在2个空位上下一条线时,有一项理解是,你的冷却部分载于和上,而前一条线没有受到约束。因此:

%ul#hello %li My List Item

为此:

<ul id= hello > <li>My List Item</li> </ul>

本条也适用于<代码>do。如果你有一条铁路,那么你需要像你那样,把助手的 block块 in起来。 Haml将自动添加<代码>end。你们应该改变你们的标志,以便看上去。

= form_for :booking, :url => booking_path(@booking), :html => { :method => :put } do |form| %ul - @booking.errors.full_messages.each do |msg| -# This is looking good so far... correct indent inside this `do` block %li= msg -# I don t feel like we are in the error messages block anymore, but you were still indented here. I ve removed the indentation to indicate that we are no longer in that block. -# This will work fine, but is there a reason you didn t use `form.label :status` here? = label :booking, :status = form.text_field :status -# I ve changed this to use `= form.` because I believe the other version (-) is deprecated = form.fields_for :user do |user_form| -# You didn t have this indented correctly. To be part of the do block you need to indent it appropriately. Fixed. = user_form.label :fullname = user_form.text_field :fullname -# This is no longer part of the `fields_for` call, so I have removed the indentation again to indicate that this is part of the outer section. = form.submit "Update this booking"

希望这将有助于: Haml可能首先感到宽松,但我发现这大有助于发展速度,我更容易阅读和书写。大约一个星期,但我上了,现在我永远不会回头:p

Im目前通过类似问题开展工作。

一、导言

class Project < ActiveRecord::Base
  has_many :meetings
end

以及儿童类别......

class Meeting < ActiveRecord::Base
  belongs_to :project
end

我发现,创建新会议的形式要求“@project”和“@meeting”(新会议目标)出席......

= form_for [@project,@meeting] do |f|
  ...

现有会议的编辑形式只需要@meetings 反对......

= form_for @meeting do |f|
  ...

您可以采取部分形式(假设你重新利用铁路公约,将_form.html.haml用于您的形式),并且只是。 html。
