js.erb未被觸發

Question

我正在嘗試使用this tutorial將新的角色添加到遊戲模型中。它大多工作得很好，除了當我點擊提交按鈕我的表單時，它根本不會調用我的create.js.erb。我在該文件的頂部放了一個警告（'hello'），以便我知道它是否被調用，事實並非如此。

其他js片段，如new.js.erb（呈現表單）和destroy.js.erb（從字符列表中刪除已銷燬的字符）正常工作。

這裏是我的代碼：

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（相關位）：

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); 

最後，我的日誌：

您應該添加：在您的控制器JS格式。嘗試改變

respond_to :html, :json 

到

respond_to :html, :json, :js
