生成器has_many结果 结果belongs_to generator
当我运行rails console:Result.find(1)时,generator_id = nil。为什么这样???当我创建数据时,路由是这样的: 本地主机:3000 /发生器/ 1 /结果/新
以下代码没有错误。我怎么在我的Generator / index.html
中有这个<% generator.results.each do |result| %>
<td><%= result.ncbi_ref_seq %></td>
<td><%= result.genome_sample %></td>
<td><%= result.binding_times %></td>
<%end%>
他们是空的。而@ generators.each做| generator |给了我发电机的价值。换句话说,属于此生成器的结果值为空,但显示的是生成器值。我想要的是显示所有生成器及其结果值。 some1可以帮助我吗?
