Question

我正在使用react-native-db-models节点模块。我的数据库模型上有3行。 =＆GT; （title | privateid | action）

这次锻炼我失去了2天。我想列出数据库中的所有记录。怎么了？

var Download = React.createClass({
    getInitialState: function () {
      return {
        dataSource: new ListView.DataSource({
          rowHasChanged: (row1, row2) => row1 !== row2,
        })
      };
    },

    componentDidMount: function() {
      this.fetchData();
    },

    fetchData: function () {
      DB.downloads.get_all(function(result) {
         var data = [];
         for(var i = 1; i <= result.totalrows; i++) {
           console.log(result.rows[i]);
           data[i-1] = result.rows[i];
           this.setState({
             dataSource: dataSource.cloneWithRows(result.rows[i]),
             loaded:false,
           })
         }

       });

    },
    render: function () {
      return (
        <ListView
         dataSource={this.state.dataSource}
         renderRow={this.renderTrack}
         style={styles.listView}/>
      );
    },
    renderTrack: function (track) {
      return (
        <View>
          <Text>{track.title}</Text>
        </View>
      );
    }
  });

这样做......

  fetchData: function () {
  DB.downloads.get_all(function(result) {
     var data = [];
     for(var i = 1; i <= result.totalrows; i++) {
       data.push(result.rows[i]);
     }
     // Outside of the loop, apply the data
       this.setState({
         dataSource: dataSource.cloneWithRows(data),
         loaded:false,
       })
   });

},

从db-models中获取Native Native Listview？
