我想使用sequelize.js来查询具有包含约束的记录的模型.我怎么做？

这就是我现在所拥有的:

Assets
  .findAll({ limit: 10, where: ["asset_name like ?", '%' + request.body.query + '%'] })
  .then(function(assets){
    return response.json({
      msg: 'search results',
      assets: assets
    });
  })
  .catch(function(error){
    console.log(error);
  });

但是我收到以下错误:

   { error: operator does not exist: character varying @> unknown

我对中间人和红宝石缺乏经验,但我一直在努力让Slate工作,所以它在构建时生成一个侧面导航/标题列表而不是客户端使用javascript.我遇到的问题是让代码包含来自partials的头文件.

目录结构的一个示例:

Source
+--config.rb
+--includes
  +--file.md
  +--otherfile.md
+--index.html
+--layouts
  +--layout.erb

布局和config.rb的要点

Config.rb代码段:

require 'nokogiri'

helpers do   
def toc_data(page_content)
    html_doc = Nokogiri::HTML::DocumentFragment.parse(page_content)

    # get a flat list of headers
    headers = []
    html_doc.css('h1, h2, h3').each do |header|
      headers.push({
        id: header.attribute('id').to_s,
        content: header.content,
        level: header.name[1].to_i,
        children: []
      })
    end

    [3,2].each do |header_level|
      header_to_nest = nil
      headers = headers.reject do |header|
        if header[:level] == header_level
          header_to_nest[:children].push header if header_to_nest
          true
        else
          header_to_nest = header if header[:level] == (header_level - 1)
          false …
