fastadmin 关联表没有name字段，有title字段

使用 data-field 属性

    <div class="form-group">
        <label class="control-label col-xs-12 col-sm-2">{:__('Goods_id')}:</label>
        <div class="col-xs-12 col-sm-8">
            <input id="c-goods_id" data-field="title" data-rule="required" min="0" data-source="bijia/goods/index" class="form-control selectpage" name="row[goods_id]" type="text" value="">
        </div>
    </div>
