在sailjs中的组合搜索

Question

我有游戏收藏:

{
  "name": "Play RoadRash",
  "version": "1.0.0",
  "icon": "image-md-two-thirds.png",
  "id": "6dc41c3fa0e7"
}

和平台集合:

{
  "name": "PlayStation",
  "version": "7",
  "icon": "playstation.jpg",
  "id": "55eaf322f1a16"
}

我试图创建一个搜索查询谁搜索在两个集合基于名称参数。有人知道如何在帆水线上搜索多重收集吗?

我们已经在所有模型中编写了一个具有全文搜索功能的控制器。它所做的就是根据请求中的q参数在所有模型及其属性中搜索。以下是该控制器的完整代码:

var _ = require('lodash');
var Promise = require('bluebird');
module.exports = {
  index: function (req, res) {
    var models = [];
    if (!req.param('q')) {
      return res.badRequest(null, null, 'You should specify a "q" parameter!');
    }
    var q = req.param('q');
    if (req.param('model')) {
      var modelStr = req.param('model').toString().toLowerCase();
      if (!(modelStr in sails.models)) {
        return res.badRequest(null, null, 'Cannot find model: ' + modelStr);
      }
      models.push({name: modelStr, model: sails.models[modelStr]});
    } else {
      _.forEach(sails.models, function (model, modelStr) {
        models.push({name: modelStr, model: model});
      });
    }
    Promise.map(models, function (modelObj) {
      var model = modelObj.model;
      var modelStr = modelObj.name;
      var where = _.transform(model.definition, function (result, val, key) {
        result.or.push(_.set({}, key, {contains: q}));
      }, {or: []});
      return model
        .find(where)
        .then(function (queryRes) {
          var resObj = {};
          resObj[modelStr] = queryRes;
          return Promise.resolve(resObj)
        });
    })
      .then(function (searchRes) {
        return _.transform(searchRes, function (result, val) {
          result = _.merge(result, val);
        }, {});
      })
      .then(res.ok)
      .catch(res.serverError)
  }
};

你可以把它复制粘贴到你的api/controllers/SearchController.js中，就是这样。它仍然需要重构这段代码，但它可以工作。
