Ruby on rails 在将slim转换为erb时遇到问题

我有这样的语法：

= form_for(@influencer.relationships.build(followed_id: @influencer.id)) do |f|
  div = f.hidden_field :followed_id
  = f.submit "Follow", class: "btn btn-large btn-primary"

这是我找到的erb，但它不工作

<%= form_for(@influencer.relationships.build(followed_id: @influencer.id)) do |f| %>
    <% f.hidden_field :followed_id %>
  <%= f.submit "Follow" %>
<% end %>

因此，您将得到：

<%= button_to "Follow", @relationship %>

您的隐藏字段需要doh！谢谢你！有趣的是，将slim转换为erb的原因是什么？我想在erb中使用一些slim代码？我所有的东西都是用erb写的，我的朋友加了这个代码，他用slim写的，所以我更喜欢用erb写的。

#app/models/influencer.rb
class Influencer < ActiveRecord::Base
   has_many :relationships, foreign_key: :follower_id
end

#app/controllers/relationships_controller.rb
class RelationshipsController < ApplicationController
   def new
      @influencer = Influencer.find params[:influencer_id]
      @relationship = @influencer.relationships.build #-> "followed_id" SHOULD be a foreign key in the model. If you have it in the model, you won't need to explicitly define it
   end
end

<%= button_to "Follow", @relationship %>
