我的模型中有一个名为 isTransfer 的字段：

class AddTxfrColumnsToTransaction < ActiveRecord::Migration
  def change
    add_column :transactions, :isTransfer, :boolean
    add_column :transactions, :transferAccount_id, :integer
  end
 end

我创建了一个控制器，它应该像 action::new 一样，但仅用于传输调用 new_transfer：

def new_transfer
  account = Account.find(params[:account_id])
  @transaction = account.transactions.build
  @transaction.description = "Transfer"
  @transaction.isTransfer = true
  @transaction.amount = 100

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

当我在我的视图表单中看到新的转移时，在发布之前，我可以看到 isTransfer 设置为 true。但是当我发布时，它总是以错误的形式进入数据库。其他字段（描述和金额）没有改变 - 它们按预期进入。

这是模型：

class Transaction < ActiveRecord::Base
  attr_accessible :account_id, :amount, :check, :date, :description, :is_cleared, :note, :category, :isTransfer, :transferAccount_id
  validates_presence_of :amount, :date

  belongs_to :account, class_name: 'Account'
  belongs_to :transferAccount, class_name: 'Account'

end

Ok, this is probably a complete noob mistake. I had originally believed that if I set a value in the controller (as part of new_transfer action) that it would persist to the create action after submit. My mistake was that in not referencing it at all on the new_transfer form, it was never passed back to the Create action as a param. By adding the following to my new_transfer form, isTransfer now updates in the create action:

<%= f.hidden_field(:isTransfer) %>

我建议您在创建控制器方法中进行预设，而不是新建

此外，您可以添加一个“！” 使 save 方法从控制台返回任何错误：例如

def create
    ###do your preset methods here
    if(@transaction.save!)

    end
end
