铁路
原标题:Rails Conditional Naming

我有一部分——铁路自动点名给我的提纲,供提出新的和ed。 在新的观点中,我倾向于将提交纽芬兰语改为“Create”而不是“CreateLink”。

我用<代码><%=格式提交“Create” %>实现了这一目的。

我将如何使铁路显示<代码><%=格式,提交“最新”%>,载于编辑观点和<%=格式.submit “Create” %> in the new,以待处理:form.html.erb正在提供? 增 编

最佳回答

@user/code>。 在此情况下,在您的介绍中:

<% editing = @user.new_record? ? false : true %>
<% default_text = editing ? "Update" : "Create" %>
<% form.submit default_text %>

我做了单独编辑和缺省——这里的文字变量,但你可以这样做:

<% form.submit @user.new_record? ? "Create" : "Update" %>

我向各位显示这些变量的唯一原因是,这种变数很容易被你以你的形式使用其他案文。

Edit I should also mention that the point of using new_record? works if for a new User (for example) you simply set @user to be User.new in your controller, but for editing you do User.find(...).
