应用制造商:在网格中显示大查询数据 [英] App maker: Show Big Query data in grid

问题描述

我在Google应用制造商中拥有一个脚本:

I having an script in googles app maker:

    function runQuery() {
  var projectId = 'blalab155512';
  var request = {
    query: 'SELECT title FROM [bigquery-public-data:samples.wikipedia]  where title contains "olimpic" LIMIT 100'
  };
  var queryResults = BigQuery.Jobs.query(request, projectId);
  var jobId = queryResults.jobReference.jobId;
  var names = queryResults.schema.fields.map(function(field){ return field.name; });


  //var records = [];  
  return queryResults.rows.map(function(row) {
  var record = app.models.Test.newRecord();
  for (var i = 0, len = names.length; i < len; ++i) {
    // Calculated model should contain correspondent fields
    // all non-defined fields will be ignored
    record[names[i]] =  (row.f[i].v);
  }

  return record;
});
}

这从Big Query给了我所需的数据.记录仪输出的数据格式:

Which gives me the desired data from Big Query. Data format output from Logger:

我现在正努力将这些数据作为计算的数据源，然后将其显示为应用程序内的网格.

I'm now struggling with put that data as an Calculated Data Source and then show it as a grid within the app.

我有一个经过计算的数据源，该数据源调用上面的脚本来获取数据.然后，我配置了一个字段(字符串)，在其中我想从查询中删除标题.

I have a calculated data source, which calls the script above to get the data. And I configured a field (String) in which I want to out the titles from the query.

在预览中未显示任何错误，但网格保持空白:

In preview no error was shown but the grid stay empty:

推荐答案

与表格"小部件不同，网格小部件不会为您生成所有嵌套的数据绑定小部件.您需要手动添加，布局和绑定所有显示窗口小部件:

Unlike Table widget, Grid widget will not generate all nested data-bound widgets for you. You need to manually add, layout and bind all display widgets:
