Question

我正在尝试使用this tutorial向游戏模型添加新角色。它主要工作得很好，除了当我单击提交按钮我的表单时，它根本不会调用我的create.js.erb。我在该文件的顶部放置了一个警告（'hello'），以便我知道它是否被调用，但事实并非如此。

其他js片段，如new.js.erb（呈现表单）和destroy.js.erb（从字符列表中删除已销毁的字符）正常工作。

这是我的代码：

查看：

#bottom of views/characters/index.html.erb
<div>
  <%= link_to "Add Character", new_play_character_path(@play), remote: true %>
</div>    
<div id="character-form" style="display:none;"></div>

形式：

<%= bootstrap_form_for([@play, @character], inline_errors: false, remote: true, layout: :horizontal, label_col: "col-sm-2", control_col: "col-sm-10" ) do |f| %>
    <%= f.text_field :name %>
    <%= f.select :age, ["Baby","Child","Teen","Young Adult","Adult","Senior"] %>
    <%= f.select :gender, ["Male","Female","Neutral"] %>
    <%= f.submit %>
<% end %>

控制器（相关位）：

class CharactersController < ApplicationController
  before_action :set_character, only: [:show, :edit, :update, :destroy]
  before_action :set_play
  respond_to :html, :json

  def index
    @characters = Character.where("play_id = #{@play.id}")

  end

  def new
    @character = Character.new
  end

  def create
    @character = @play.characters.build(character_params)
    flash[:notice] = "Character was successfully created." if @character.save
    respond_with(@play)
  end

create.js.erb

alert('hello');
$('#characters').html("<%= j render(@play.characters) %>");
$('#character-form').slideUp(350);

最后，我的日志：

您应该在控制器中添加：js格式。尝试改变

respond_to :html, :json

到

respond_to :html, :json, :js

js.erb没有被触发
