Question

我尝试使用AJAX添加新对象，但我得到的只是＃34;无法加载资源：服务器响应状态为500（内部服务器错误）＆＃34;。

我花了大约4个小时试图找到解决方案，接着是2个教程，但这个错误从未离开过我。

我的characters_controller.rb

class CharactersController < ApplicationController

def index
    @characters = Character.all.order("id DESC")
end

def create
    @character = Character.new(params[:character])

    if @character.save  
        flash[:notice] = "Successfully created post."
    end

    respond_to do |format|
        format.js
    end
end
end

index.html.erb

<div class="header">
    <p>All Hobbit characters</p>
</div>

<div class="characters">
    <%= render @characters %>
</div>

<%= form_for(Character.new, :remote => true) do |f| %>
    <div class="field">
        <%= f.label :name %><br />
        <%= f.text_field :name %>
    </div>
    <div class="actions">
        <%= f.submit %>
    </div>
<% end %>

create.js.erb

<% if @character.new_record? %>
    $('input#character_name').effect('highlight', {color: 'red'});
<% else %>
    $('div#characters').append("<%= escape_javascript(render @character) %>");
    $('div#<%= dom_id(@character) %>').effect('highlight');
<% end %>

从Rails 4开始，您无法将params[:character]直接传递给Character.new方法。尝试这样的事情：

def create
    @character = Character.new(character_params)
    if @character.save  
        flash[:notice] = "Successfully created post."
    end
    respond_to do |format|
        format.js
    end
end

private

def character_params
  params.require(:character).permit(:name)
end

Rails不引人注目的javascript - 无法加载资源
