我需要通过Flask网络应用程序将大型数据集提供到网络上的表格中。我正在尝试使用bootstrap-table extension实现服务器端分页,但我无法使其正常工作。关于它的一些事情,我不理解。当表呈现时,它正确地知道我的表中的行数,并构建适当的页面列表。但是,表中的所有行都会在每个页面上呈现。
此外,此表的排序和搜索功能仅返回完整表。 bootstrap-table.js代码似乎具有用于对服务器端数据进行排序和搜索的功能,但我不确定。
我的引导程序表代码如下所示
<table class='sastable' id='servertable' data-toggle="table" data-classes='table table-condensed table-bordered'
data-url="/manga/gettable"
data-show-columns='true' data-toolbar='#toolbar' data-id-field='id'
data-pagination="true" data-side-pagination="server"
data-page-list="[10, 20, 50, 100]" data-search="true">
<thead>
<tr id='head'>
<th data-field="state" data-checkbox="true">ID</th>
<th data-field="id" id='id' data-visible='false' data-switchable='false'>ID</th>
{% for column in keys %}
<th id='{{column}}' data-field='{{column}}' data-sortable='true' data-sorter="sort"
data-cell-style="{{'cellStyle' if (column=='plate' or 'status' in column or 'comp' in column) else ''}}"
data-visible="{{'false' if column not in cols else 'true'}}">{{column|upper}}</th>
{% endfor %}
</tr>
</thead>
其中我的data-url属性'/ manga / gettable'是以这种格式返回JSON数据的链接,jsfiddle
在/ manga / gettable中传递数据的代码是
@tables_page.route('/manga/gettable', methods=['GET','POST'])
@tables_page.route('/gettable', methods=['GET','POST'])
def getTable():
''' Retrieve tables for server-side delivery '''
pl = plateList()
pl.load()
table = pl.plate2d
size = len(table)
data = OrderedDict()
data['total'] = size
data['rows'] = []
cols = table.columns.keys()
for row in table:
data['rows'].append({col:row.data[i] for i,col in enumerate(cols)})
return jsonify(data)
基本上只是从文件中加载一个表,并将其转换为JSON字典类型格式。这个表有大约50行,并正确地制作5页,假设每页默认10条记录,但实际上每页显示50行。
一个可信的工作示例,正确的分页,排序和搜索是here,但我不明白它是如何工作的。
我觉得我在这里缺少一些基本的东西。我在这里错过了什么?谢谢。

我在django上解决了这个问题:
我的js:
$(document).ready(function(){
...
ajaxGet();
});
function ajaxGet(){
var table_params = $('#docs_table').bootstrapTable({
url: 'ajax/test_1/data?',
queryParams: function (p) {
return {
limit: p.limit,
offset: p.offset,
sort: p.sort,
order: p.order,
'data[]': [selected_data],//for multi-select filter
};
}
});
$('#docs_table').bootstrapTable('refresh');
}
吡啶:
def test_1(request):
q = m.Doc.objects.all()
data = request.GET.get('data[]')
if data:
data = data.split(',')
q = q.filter(id__in=pis)
paginator = Paginator(q, 10)
sort = request.GET.get('sort', 'id')
order = request.GET.get('order', 'asc')
limit = int(request.GET.get('limit'))
offset = int(request.GET.get('offset'))
if order == 'asc':
q = q.order_by(sort)
else:
q = q.order_by('-' + sort)
paginator = Paginator(q, limit)
page = int(offset / limit) + 1
try:
docs = paginator.page(page)
except PageNotAnInteger:
docs = paginator.page(1)
except EmptyPage:
docs = paginator.page(paginator.num_pages)
docs_dict = {
'total': paginator.count,
'rows': [{'id': doc.id,
'name': doc.name,
} for doc in docs]
}
return JsonResponse(docs_dict)

表示您需要在服务器端实现分页。
您的服务器代码缺少处理页码,每页行数,订单等的内容。服务器应该只返回该页面的行。
查看官方示例,并在更改页面时观察ajax返回值。 http://wenzhixin.net.cn/p/bootstrap-table/docs/examples.html#server-side-pagination-table
这是请求&amp;返回第4页,10行。
请求网址:
server-side pagination
返回值:
http://wenzhixin.net.cn/examples/bootstrap_table/data?limit=10&offset=30&order=asc
