实现组织架构和用户绑定,通过绑定按钮设置组织架构和用户之间一对多的关联关系。
打开sandboxMP/apps/system/views_structure.py,添加如下内容:
from django.contrib.auth import get_user_model
User = get_user_model()
class Structure2UserView(LoginRequiredMixin, View):
def get(self, request):
if ‘id‘ in request.GET and request.GET[‘id‘]:
# 通过id获取需要绑定用户的组织架构实例
structure = get_object_or_404(Structure, pk=int(request.GET[‘id‘]))
# 通过外键的反向查找(_set),找到已经绑定到该组织架构的所有用户信息
added_users = structure.userprofile_set.all()
# 查找系统中所有用户信息,User = get_user_object()使用自定义用户模型都是通过这种模式
all_users = User.objects.all()
# 通集合获取差集set().difference(),得出还未绑定的用户
un_add_users = set(all_users).difference(added_users)
# 将这些数据返回给前端,用来渲染数据,形成一个复选框,左边是未绑定用户,右边是已经绑定的用户
ret = dict(structure=structure, added_users=added_users, un_add_users=list(un_add_users))
return render(request, ‘system/structure/structure_user.html‘, ret)
def post(self, request):
res = dict(result=False)
id_list = None
# 通过id获取structure实列
structure = get_object_or_404(Structure, pk=int(request.POST[‘id‘]))
# 获取需要绑定到structure实例的用户id
if ‘to‘ in request.POST and request.POST.getlist(‘to‘, []):
id_list = map(int, request.POST.getlist(‘to‘, []))
# 清空组织架构原有用户绑定信息
structure.userprofile_set.clear()
if id_list:
# 绑定新的用户数据
for user in User.objects.filter(id__in=id_list):
structure.userprofile_set.add(user)
res[‘result‘] = True
return HttpResponse(json.dumps(res), content_type=‘application/json‘)
视图实现思路:参照代码中的注释。
打开sandboxMP/apps/system/urls.py, 新增URL配置:
urlpatterns = [
‘‘‘原有内容省略‘‘‘
path(‘basic/structure/add_user/‘, views_structure.Structure2UserView.as_view(), name=‘basic-structure-add_user‘),
]
新建sandboxMP/templates/system/structure/structure_user.html,内容如下:
{% extends ‘base-layer.html‘ %}
{% load staticfiles %}
{% block css %}
<link rel="stylesheet" href="{% static ‘plugins/select2/select2.min.css‘ %}">
{% endblock %}
{% block main %}
<div class="box box-danger">
<form class="form-horizontal" id="selectUsersForm" action="" method="post">
{% csrf_token %}
<input type="hidden" name=‘id‘ value="{{ structure.id }}"/>
<div class="box-body">
<div class="row">
<div class="col-xs-5">
<label class="control-label">可选用户:</label>
<select name="from" id="multiselect" class="form-control" size="18" multiple="multiple">
{% for item in un_add_users %}
<option value="{{ item.id }}">{{ item.name }}({{ item.username }})</option>
{% endfor %}
</select>
</div>
<div class="col-xs-2">
<br><br><br><br><br><br>
<button type="button" id="multiselect_rightAll" class="btn btn-block"><i
class="glyphicon glyphicon-forward"></i></button>
<button type="button" id="multiselect_rightSelected" class="btn btn-block"><i
class="glyphicon glyphicon-chevron-right"></i></button>
<button type="button" id="multiselect_leftSelected" class="btn btn-block"><i
class="glyphicon glyphicon-chevron-left"></i></button>
<button type="button" id="multiselect_leftAll" class="btn btn-block"><i
class="glyphicon glyphicon-backward"></i></button>
</div>
<div class="col-xs-5">
<label class="control-label">编辑:{{structure.name}}-已绑定用户:</label>
<select name="to" id="multiselect_to" class="form-control" size="18" multiple="multiple">
{% for item in added_users %}
<option value="{{ item.id }}">{{ item.name }}({{ item.username }})</option>
