我有一个允许用户创建新项目的页面。他们可以选择从链接到表格列的下拉菜单中进行选择，以防他们正在寻找的选项已经在数据库中，以及他们可以输入新数据的另一个选项，即在提交项目时，该文件的新数据将保存到下一个人的数据库中。
这是我的新/编辑项目视图的一部分：
<div class="client">
<%= label_tag :new_client, "Client" %><br/>
<%= text_field_tag :new_client, nil, :maxlength => 30 %>
Or
<%= f.select( :client, Project.all.map {|p| [p.client]}.uniq, :prompt => "Select a previous Client") %>
</div>
用户可以通过文本字段输入新数据，也可以从下拉列表中选择。如果用户将新数据放入文本框中并从下拉列表中选择某些内容，则新数据将与项目一起保存，因为它具有优先级。
我的问题在于编辑视图：
当用户单击编辑链接时，项目会显示他们输入的所有数据，但所有数据都保存在下拉菜单中。
如果他们尝试在文本框中输入新数据并保存项目，它将与下拉菜单中突出显示的内容一起保存，并忽略放入文本框中的新数据。
编辑视图与新视图完全相同。
谁能指出我正确的方向。我是 Rails 新手，所以在尝试提供帮助时请记住这一点。
提前致谢。
