Rails simple_form 两个模型

发布于 2024-11-07 00:54:19 字数 477 浏览 2 评论 0原文

我开始将 simple_form 用于 Rails 应用程序，在转换一些表单时，我遇到了一个正在使用的有两个模型的表单，有点像嵌入式表单。这可以用 simple_form 实现吗？

 <% simple_form_for :topic, :url => forum_topics_path do |t| %>
 <%= t.input :name, :label => 'Topic' %></p>

 <p>First Post:<br/></p> 
 Title: <%= text_field :post, :title %> <--- this is where i start having problems
 Body: <%= text_area :post, :body %>
 <%= t.submit 'Save' %>

谢谢

I'm starting to use simple_form for a rails application, and while converting some of my forms, I came across one that has two models that it is working with, sort of an embedded form. Is this possible with simple_form?

 <% simple_form_for :topic, :url => forum_topics_path do |t| %>
 <%= t.input :name, :label => 'Topic' %></p>

 <p>First Post:<br/></p> 
 Title: <%= text_field :post, :title %> <--- this is where i start having problems
 Body: <%= text_area :post, :body %>
 <%= t.submit 'Save' %>

Thanks

使用 simple_fields_for ：

<%= simple_form_for :topic, :url => forum_topics_path do |topic_builder| %>
  <%= topic_builder.input :name, :label => 'Topic' %>
  <%= topic_builder.simple_fields_for :post do |post_builder| %>
    <p>First Post:</p> 
    <%= post_builder.input :title, :input_html => { :size => 30 } %>
    <%= post_builder.input :body, :as => :text, :input_html => { :rows => 20, :cols => 50, :class => 'resizable' } %>
  <% end %>
  <%= topic_builder.submit 'Save' %>
<% end %>

注释

注意 <%= simple_form_for ... 和 <%= simple_fields_for 中的 = 符号（Rails 3.x 中必需）
删除了“标题：”和“正文：”文本。使用为输入生成的标签，并根据需要使用 CSS 设置其位置的样式。
添加了使用 input_html 的示例

Use simple_fields_for :

<%= simple_form_for :topic, :url => forum_topics_path do |topic_builder| %>
  <%= topic_builder.input :name, :label => 'Topic' %>
  <%= topic_builder.simple_fields_for :post do |post_builder| %>
    <p>First Post:</p> 
    <%= post_builder.input :title, :input_html => { :size => 30 } %>
    <%= post_builder.input :body, :as => :text, :input_html => { :rows => 20, :cols => 50, :class => 'resizable' } %>
  <% end %>
  <%= topic_builder.submit 'Save' %>
<% end %>

Notes

Note the = symbol in <%= simple_form_for ... and <%= simple_fields_for (required in Rails 3.x)
Removed "Title:" and "Body:" text. Use the label generated for the inputs and style their location with CSS as needed.
Added example of using input_html
