环境：xadmin-for-python3 python3.5.2 django1.9.12
主要思路：利用django-xadmin的插件原理和原有分页插件的逻辑，单独定义一个分页显示数插件，效果如下“每页”：
以下为相关代码：
1. 新建一个plugins/listperpage.py
from django.utils.safestring import mark_safeimport xadmin
from xadmin.views import BaseAdminPlugin
from django.template import loader
from django.utils.html import escapeclass ListPerPagePlugin(BaseAdminPlugin):
show_list_per_page = True
list_per_page_choices = [20, 50, 100, 500] def init_request(self, *args, **kwargs):
try:
self.admin_view.list_per_page = int(self.request.GET.get('list_per_page', self.admin_view.list_per_page))
except ValueError as e:
print(repr(e)) if self.admin_view.list_per_page>10000:
self.admin_view.list_per_page = 10000 # 最大10000 return bool(self.show_list_per_page) def get_context(self, context):
list_per_page_range = []
for per_page in self.list_per_page_choices:
list_per_page_range.append(mark_safe('<a href="%s" rel="external nofollow" %s><p class="text-left">%d</p></a> ' % (escape(self.get_query_string({'list_per_page': per_page})),
(per_page == self.admin_view.list_per_page and ' class="btn btn-sm disabled"' or ' class="btn btn-sm"'), per_page))) context.update({'list_per_page_range': list_per_page_range, 'list_per_page_required': (not self.admin_view.show_all or not self.admin_view.can_show_all) and self.admin_view.multi_page})
return context # 对应model_list.html中的view_block 'bx_list_per_page'
def block_bx_list_per_page(self, context, nodes):
nodes.append(loader.render_to_string('base/blocks/bx_list_per_page.html', context_instance=context))
新建bx_list_per_page.html文件：
{% if list_per_page_required %}
<div class="dropdown" style="display:inline-block;">
<button class="btn btn-default btn-sm dropdown-toggle" style="line-height:1.42" type="button" data-toggle="dropdown">每页
<span class="caret"></span></button>
<ul class="dropdown-menu">
{% for num in list_per_page_range %}
<li>{{ num }}</li>
{% endfor %}
</ul>
</div>
{% endif %}
2. 在合适的adminx.py中注册这个plugin， 注意这个adminx.py文件所在的app package必须是有配置在INSTALLED_APPS中：
from xadmin.views import ListAdminView
from .plugins.listperpage import ListPerPagePlugin
xadmin.site.register_plugin(ListPerPagePlugin, ListAdminView)
3. 更改djano-xadmin中的model_list.html文件，分页部分增加了
view_block 'bx_list_per_page' ：
<ul class="pagination pagination-sm pagination-left pagination-inline">
{% view_block 'pagination' 'small' %}<li>{% view_block 'bx_list_per_page' %}</li>
</ul>
