第十章、kingadmin+admin+actions功能开发
10.1. django admin的action
可以自己写个函数执行批量操作
crm/admin.py
后台admin action就会多一个change status,可以修改status状态
执行后
10.2.kingadmin actions功能开发
(1)crm/kingadmin.py
(2)kingamdin/admin_base.py
class BaseKingAdmin(object): list_display = []
list_filter = []
search_fields = []
#只读
readonly_fields = []
filter_horizontal = []
list_per_page = 5
actions = []
(3)table_obj_list.html
加个action框+"单选/全选/全部取消"+执行按钮
<form>
<div class="row">
<div class="col-lg-3">
<select class="form-control" name="action">
<option value="">-------</option>
{% for action in admin_class.actions %}
<option value="{{ action }}">{{ action }}</option>
{% endfor %}
</select>
</div>
<div class="col-lg-2">
<input type="submit" value="执行" class="btn btn-primary" style="padding: 6px">
</div>
</div>
</form>
给所有客户信息添加一个可选框
th用来全选
每个td都要加
js代码(可以全选/取消全选)
<script> function SelectALLObjs(ele) { if ($(ele).prop('checked')){
$('input[row-select]').prop('checked',true) }else{
$('input[row-select]').prop('checked',false)
}
} </script>
效果:
执行action
table_obj_list.html
js代码
function ActionCheck(ele){
var selected_action = $("select[name='action']").val();
var selected_objs = $("input[row-select]").filter(":checked");
console.log($("select[name='action']").val())
if (!selected_action){
alert("no action selected!")
return false
}
if (selected_objs.length == 0 ){
alert("no object selected!")
return false
}else {
//生成一个标签,放到form里 var selected_ids = [];
$.each(selected_objs,function () {
console.log($(this) );
selected_ids.push($(this).val())
})
console.log(selected_ids)
var input_ele = "<input type='hidden' name='selected_ids' value=" + JSON.stringify(selected_ids) + ">" $(ele).append(input_ele);
}
}
后台kingadmin/views.py
现在就可以批量执行action操作了。
10.3.添加默认的delete action
(1)kingadmin/admin_base.html
- 添加一个default_actions = ['delete_selected_objs'],不能直接加载actions里面,因为子类会覆盖父类的actions
- 利用__init__方法,把defautl_actions里面的值添加到actions里面。
# kingadmin/admin_base.py import json
from django.shortcuts import render class BaseKingAdmin(object): def __init__(self):
self.actions.extend(self.default_actions) list_display = []
list_filter = []
search_fields = []
#只读
readonly_fields = []
filter_horizontal = []
list_per_page = 5
default_actions = ['delete_selected_objs']
actions = [] def delete_selected_objs(self,request,querysets): querysets_ids = json.dumps([i.id for i in querysets]) return render(request,'kingadmin/table_obj_delete.html',{'admin_class':self, #self就是admin_class
'objs':querysets,
'querysets_ids':querysets_ids
})
(2)table_obj_delete.html
(3)kingadmin/views.py
在views中要对post进行判断(因为“执行”和“确认删除” 都是post动作,同时存在在def table_obj_list里面)
效果:
