如何从 Rails 中的同一页面提交多个重复的表单 - 最好使用一个按钮

问题描述：

在我的新视图页面中，我有:

In my new views page I have:

<% 10.times do %>
  <%= render 'group_member_form' %>     
<% end %>

现在此表单包含以下字段:first_name、last_name、email_address 和 mobile_number.基本上，我希望能够一键填写所有表单的字段，然后将每个表单作为唯一的行/id 提交到数据库中.

Now this form contains the fields: first_name, last_name, email_address and mobile_number. Basically I want to be able to fill in the fields of all the forms in one click which then submits each into the database as a unique row/id.

实现这一目标的最简单方法是什么?

What would be the easiest way to accomplish this?

注意:从变量调用 do 的次数.欢迎任何建议，谢谢！

Note: The number of times do is called from a variable. Any advice welcome, thanks!

答

你应该只有一个表单(你应该只在 group_member_form 部分中放置字段).在您看来，您应该具有以下内容:

You should have only one form (you should put only fields in the group_member_form partial). In your view you should have something like:

<%= form_tag "/members" do %>
  <% 10.times do %>
    <%= render 'group_member_form' %>     
  <% end %>
  <%= submit_tag "Submit" %>
<% end %>

在_group_member_form.html.erb中你应该有

<%= text_field_tag "members[][first_name]" %>
<%= text_field_tag "members[][last_name]" %>
<%= text_field_tag "members[][email_address]" %>
<%= text_field_tag "members[][mobile_number]" %>

这样，当表单提交时，控制器中的 params[:members] 将是一个成员哈希数组.因此，例如，要在提交表单后从第四个成员那里获取电子邮件地址，请调用 params[:members][3][:email_adress].

This way, when the form submits, params[:members] in the controller will be an array of member hashes. So, for example, to get the email adress from the fourth member after submitting the form, you call params[:members][3][:email_adress].

要理解我为什么这样写_group_member_form.html.erb，请看一下:

To understand why I wrote _group_member_form.html.erb like this, take a glance at this:
