我的应用程序中有以下内容：

# some_view_file.html.haml
= best_in_place element, :inbox, :type => :checkbox

# imap_accounts_controller.rb
def update
  element = ImapAccount.find(params[:id])
  element.update_attributes(params[:imap_account])
  respond_with element
end

但是布尔模型属性不会更新。也不会抛出任何错误。知道为什么我的应用程序不将"true"or"false"字符串转换为布尔值。

我已经按照文档中的说明进行了操作。但似乎 Rails 4 默认情况下通常不开放以从视图/控制器接收布尔值，就像在这个 SO post 中举例说明的那样。

你可以通过这样做来解决你当前的问题......

# imap_accounts_controller.rb
def update
  element = ImapAccount.find(params[:id])
  element.update_attributes(params[:imap_account] == "true")
  respond_with element
end

或者，如果参数值是“1”，正如 best_in_place 文档所说，那么它将是

# imap_accounts_controller.rb
def update
  element = ImapAccount.find(params[:id])
  element.update_attributes(params[:imap_account] == "1")
  respond_with element
end

这个 gem 看起来也可以很好地工作https://github.com/prodis/wannabe_bool
