篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Teamcenter_SOA开发：使用查询构建器查询数据相关的知识，希望对你有一定的参考价值。
Teamcenter中的查询构建器可以查询对象信息，今天使用Item Name这个查询来查询Teamcenter中的对象，并打印出对象的信息。搭建环境参见Teamcenter_SOA开发：使用SOA登录Teamcenter - huangym1 - 博客园 (cnblogs.com)

黄河远上白云间，一片孤城万仞山。
羌笛何须怨杨柳，春风不度玉门关。
诗人初到凉州，面对黄河、边城的辽阔景象，又耳听着《折杨柳》曲，有感而发，写成了这首表现戍守边疆的士兵思念家乡情怀的诗作。
诗的前两句描绘了西北边地广漠壮阔的风光。首句抓住自下（游）向上（游）、由近及远眺望黄河的特殊感受，描绘出“黄河远上白云间”的动人画面：汹涌澎湃波浪滔滔的黄河竟像一条丝带迤逦飞上云端。写得真是神思飞跃，气象开阔。诗人的另一名句“黄河入海流”，其观察角度与此正好相反，是自上而下的目送；而李白的“黄河之水天上来”，虽也写观望上游，但视线运动却又由远及近，与此句不同。“黄河入海流”和“黄河之水天上来”，同是着意渲染黄河一泻千里的气派，表现的是动态美。而“黄河远上白云间”，方向与河的流向相反，意在突出其源远流长的闲远仪态，表现的是一种静态美。同时展示了边地广漠壮阔的风光，不愧为千古奇句。
python测试开发django-117.bootstrapTable结合Paginator分页器查显示表格
前言
bootstrap 提供了table表格插件，可以快速帮我们实现分页功能。这样就不用在前端页面上写分页逻辑，只需关注后端给对应数据就行。
bootstrap-table提供两种分页方式，client和server，即客户端和服务端分页；
- client分页：后台一次性返回所有数据，前台翻页时不再请求后台（数据量很大的时候会导致查询很慢）。
- server分页：后台根据前台每次翻页时传递的参数，可以结合Paginator分页器查询每个页码对应的数据，每次只返回对应页面的数据

bootstrapTable实现数据加载
script 中bootstrapTable 几个摘要参数
url: 访问数据的接口，需返回json对象，如：{“total”: 2,“rows”: [{“id”: 0,“name”: “Item 0”,“price”: “$0”},]
columns: table表格中显示的字段和名称
queryParams：查询的时候，提交查询参数
<body>
<div class="container">
<h1>bootstrapTable实例</h1>
<hr/>
<div id="toolbar" class="btn-group">
<button id="btn_add" type="button" class="btn btn-default">
<span class="glyphicon glyphicon-plus" aria-hidden="true"></span>新增
</button>
<button id="btn_edit" type="button" class="btn btn-default">
<span class="glyphicon glyphicon-pencil" aria-hidden="true"></span>修改
</button>
<button id="btn_delete" type="button" class="btn btn-default">
<span class="glyphicon glyphicon-remove" aria-hidden="true"></span>删除
</button>
</div>
<table id="table" class="table table-striped"></table>
</div>
</body>
<script>
var url = '/teacher/info';
var columns = [
{
checkbox: true,
visible: true //是否显示复选框
},
{
field: 'id',
title: 'ID'
}, {
field: 'name',
title: '姓名'
}, {
field: 'age',
title: '年龄'
},
{
field: 'tel',
title: '电话'
}
];
$("#table").bootstrapTable({
toolbar: '#toolbar', //自定义工具按钮
url: url, //请求后台的URL（*）
method: 'get', //请求方式（*）
cache: false, //是否使用缓存，默认为true，所以一般情况下需要设置一下这个属性（*）
pagination: true, //是否显示分页（*）
pageSize: 10, //每页的记录行数（*）
pageList: [10, 20, 50, 100, 'All'], //可供选择的每页的行数（*）
sidePagination: "server", //分页方式：client客户端分页，server服务端分页（*）
pageNumber: 1, //初始化加载第一页，默认第一页
//search: true, //是否显示表格搜索
showColumns: true, //是否显示所有的列
showRefresh: true, //是否显示刷新按钮
minimumCountColumns: 2, //最少允许的列数
//height: 500, //行高，如果没有设置height属性，表格自动根据记录条数决定表格高度
showToggle: true, //是否显示详细视图和列表视图的切换按钮
columns: columns, //列参数
//detailView: true, //是否显示父子表
//得到查询的参数，会在url后面拼接，如：?rows=5&page=2&sortOrder=asc&search_kw=&_=1564105760651
queryParams: function (params) {
//这里的键的名字和控制器的变量名必须一直，这边改动，控制器也需要改成一样的
var query_params = {
page: (params.offset / params.limit) + 1, //页码
size: params.limit, //页面大小
//查询框中的参数传递给后台
//search_kw: $('#search-keyword').val(), // 请求时向服务端传递的参数
};
return query_params;
},
});
//得到查询的参数
</script>
</html>
视图
查询结果必须是json格式:{“total”: 2,“rows”: [{},{}]},其中total和rows名称必须保持一致，前端才能加载到数据
from django.core.paginator import Paginator, PageNotAnInteger, EmptyPage
from django.db.models import Q
from django.forms.models import model_to_dict
# 作者-上海悠悠 QQ交流群:717225969
# blog地址 https://www.cnblogs.com/yoyoketang/
def teacherpage(request):
return render(request, 'boot_table.html')
def teacherInfo(request):
"""
查询结果必须是json格式:{"total": 2,"rows": [{},{}]}
"""
if request.method == "GET":
# search_kw = request.GET.get('search_kw', None)
# 获取分页参数用于查询对应页面数据，page为第几页，size为每页数据条数
page_num = request.GET.get('page', 1)
size = request.GET.get('size', 10)
# 查询全部
teachers = Teacher.objects.all()
# 使用分页器返回查询的页数和size
paginator = Paginator(teachers, per_page=size)
page_object = paginator.page(page_num)
# 总数
total = teachers.count()
# 查询list of dict
rows = [model_to_dict(i) for i in page_object]
# print(rows)
return JsonResponse({'total': total, 'rows': rows})
页面展示效果
默认每页查询10条数据
可以修改每页显示的条数
queryParams 查询
queryParams查询对应的参数
- params.limit 是每页的条数，一般对应size参数
- params.offset 是起始位置的数目，对应的page需要计算得到(params.offset / params.limit) + 1
- search_kw 对应搜索框内容，需设置.bootstrapTable属性 search: true
toolbar 工具
toolbar 对应table表格上的新增/修改/删除
<div id="toolbar" class="btn-group">
<button id="btn_add" type="button" class="btn btn-default">
<span class="glyphicon glyphicon-plus" aria-hidden="true"></span>新增
</button>
<button id="btn_edit" type="button" class="btn btn-default">
<span class="glyphicon glyphicon-pencil" aria-hidden="true"></span>修改
</button>
<button id="btn_delete" type="button" class="btn btn-default">
<span class="glyphicon glyphicon-remove" aria-hidden="true"></span>删除
</button>
</div>
此部分后端接口还没实现
