使用带有fields_for的数组 [英] using an array with fields_for

问题描述

如何使用fields_for遍历对象数组(所有相同模型)? 该数组包含由current_user创建的对象.

How can I iterate through an array of objects (all the same model) using fields_for ? The array contains objects created by the current_user.

我目前有:

<%= f.fields_for :descriptionsbyuser do |description_form| %>
<p class="fields">
    <%= description_form.text_area :entry, :rows => 3 %>
    <%= description_form.link_to_remove "Remove this description" %>
    <%= description_form.hidden_field :user_id, :value => current_user.id %>
</p>
<% end %>

但是我想将:descriptionsbyuser替换为我在控制器中创建的数组-@descriptionsFromCurrentUser

But I want to replace the :descriptionsbyuser with an array I created in my controller - @descriptionsFromCurrentUser

这也位于Ryan Bate的"nested_form_for"中

This is also inside Ryan Bate's "nested_form_for"

任何指针将不胜感激！

推荐答案

文档fields_for 清楚地向您展示了使用数组的方式:

Docs for fields_for clearly shows you the way of using arrays:

或要使用的集合:

Or a collection to be used:

<%= form_for @person do |person_form| %>
  ...
  <%= person_form.fields_for :projects, @active_projects do |project_fields| %>
    Name: <%= project_fields.text_field :name %>
  <% end %>
  ...
<% end %>

@active_projects这是您的数组.
