菜单包括菜单列表&＃xff0c;菜单列表不仅将菜单列出来&＃xff0c;而且将每个菜单下的权限也列出来、菜单的添加、删除、修改。
urls.py
...re_path(r&＃39;^menus/list/$&＃39;, MenuView.as_view(), name&＃61;&＃39;menus_list&＃39;),re_path(r&＃39;^menus/add/$&＃39;, MenuAddView.as_view(), name&＃61;&＃39;menus_add&＃39;),re_path(r&＃39;^menus/edit/(?P
1、后台处理菜单列表页
class MenuView(View):def get(self,request):menu_queryset&＃61;Menu.objects.all()pid&＃61;request.GET.get(&＃39;pid&＃39;)if pid:root_permission_queryset &＃61; Permission.objects.filter(menu_id&＃61;pid).values(&＃39;id&＃39;, &＃39;title&＃39;, &＃39;url&＃39;, &＃39;name&＃39;, &＃39;parent_id&＃39;,&＃39;menu__title&＃39;)else:root_permission_queryset &＃61; Permission.objects.filter(menu_id__isnull&＃61;False).values(&＃39;id&＃39;, &＃39;title&＃39;, &＃39;url&＃39;, &＃39;name&＃39;, &＃39;parent_id&＃39;,&＃39;menu__title&＃39;)# print(&＃39;permission_queryset&＃39;,root_permission_queryset)
all_root_permission_queryset&＃61;Permission.objects.all().values(&＃39;id&＃39;, &＃39;title&＃39;, &＃39;url&＃39;, &＃39;name&＃39;, &＃39;parent_id&＃39;)root_permission_dict&＃61;{}for row in root_permission_queryset:if not row[&＃39;parent_id&＃39;]:root_permission_dict[row[&＃39;id&＃39;]]&＃61;{&＃39;id&＃39;:row[&＃39;id&＃39;],&＃39;title&＃39;:row[&＃39;title&＃39;],&＃39;name&＃39;:row[&＃39;name&＃39;],&＃39;url&＃39;:row[&＃39;url&＃39;],&＃39;menu_title&＃39;:row[&＃39;menu__title&＃39;],&＃39;children&＃39;:[]}for row in all_root_permission_queryset:parent_id&＃61;row[&＃39;parent_id&＃39;]if parent_id in root_permission_dict:root_permission_dict[parent_id][&＃39;children&＃39;].append({&＃39;id&＃39;:row[&＃39;id&＃39;],&＃39;title&＃39;:row[&＃39;title&＃39;],&＃39;name&＃39;:row[&＃39;name&＃39;],&＃39;url&＃39;:row[&＃39;url&＃39;]})print(root_permission_dict)return render(request,&＃39;rbac/menu_list.html&＃39;,{&＃39;menu_queryset&＃39;:menu_queryset,&＃39;root_permission_dict&＃39;:root_permission_dict,&＃39;pid&＃39;:pid})
将每一个菜单及其权限取出来&＃xff0c;组成相应的数据结构
{64: {&＃39;id&＃39;: 64,&＃39;name&＃39;: &＃39;rbac:multi_permissions&＃39;,&＃39;menu_title&＃39;: &＃39;权限管理&＃39;,&＃39;title&＃39;: &＃39;批量添加权限&＃39;,&＃39;children&＃39;: [],&＃39;url&＃39;: &＃39;/rbac/multi/permissions/&＃39;},1: {&＃39;id&＃39;: 1,&＃39;name&＃39;: &＃39;stark:crm_userinfo_changelist&＃39;,&＃39;menu_title&＃39;: &＃39;权限管理&＃39;,&＃39;title&＃39;: &＃39;用户列表&＃39;,&＃39;children&＃39;: [{&＃39;id&＃39;: 2,&＃39;name&＃39;: &＃39;stark:crm_userinfo_add&＃39;,&＃39;title&＃39;: &＃39;添加用户&＃39;,&＃39;url&＃39;: &＃39;/stark/crm/userinfo/add/&＃39;}, {&＃39;id&＃39;: 3,&＃39;name&＃39;: &＃39;stark:crm_userinfo_change&＃39;,&＃39;title&＃39;: &＃39;修改用户&＃39;,&＃39;url&＃39;: &＃39;/stark/crm/userinfo/(?P
}
2、处理添加菜单
添加以及修改使用的都是modelform
from django import forms
from rbac import models
from django.utils.safestring import mark_safeICON_LIST &＃61; [[&＃39;fa fa-address-book&＃39;, &＃39;&＃39;],[&＃39;fa fa-address-book-o&＃39;, &＃39;&＃39;],[&＃39;fa fa-address-card&＃39;, &＃39;&＃39;],[&＃39;fa fa-address-card-o&＃39;, &＃39;&＃39;],[&＃39;fa fa-adjust&＃39;, &＃39;&＃39;],[&＃39;fa fa-american-sign-language-interpreting&＃39;,&＃39;&＃39;],[&＃39;fa fa-stack-overflow&＃39;, &＃39;&＃39;],[&＃39;fa fa-clipboard&＃39;, &＃39;&＃39;],]for item in ICON_LIST:item[1]&＃61;mark_safe(item[1])class MenuModelForm(forms.ModelForm):class Meta:model&＃61;models.Menufields&＃61;[&＃39;title&＃39;,&＃39;icon&＃39;]widgets &＃61; {&＃39;title&＃39;: forms.TextInput(attrs&＃61;{&＃39;placeholder&＃39;: &＃39;请输入菜单名称&＃39;, &＃39;class&＃39;: &＃39;form-control&＃39;}),&＃39;icon&＃39;:forms.RadioSelect(choices&＃61;ICON_LIST)}
class MenuAddView(View):def get(self,request):form &＃61; MenuModelForm()return render(request,&＃39;rbac/menu_add.html&＃39;,{&＃39;form&＃39;:form})def post(self,request):form&＃61;MenuModelForm(data&＃61;request.POST)if form.is_valid():form.save()return redirect(reverse(&＃39;rbac:menus_list&＃39;))return render(request,&＃39;rbac/menu_add.html&＃39;,{&＃39;form&＃39;:form})
3、处理修改菜单
class MenuEditView(View):def get(self,request,mid):menu_obj&＃61;Menu.objects.filter(id&＃61;mid).first()if not menu_obj:return HttpResponse(&＃39;该菜单不存在&＃39;)form&＃61;MenuModelForm(instance&＃61;menu_obj)return render(request,&＃39;rbac/menu_edit.html&＃39;,{&＃39;form&＃39;:form})def post(self,request,mid):menu_obj&＃61;Menu.objects.filter(id&＃61;mid).first()form&＃61;MenuModelForm(data&＃61;request.POST,instance&＃61;menu_obj)if form.is_valid():form.save()return redirect(reverse(&＃39;rbac:menus_list&＃39;))return render(request, &＃39;rbac/menu_edit.html&＃39;, {&＃39;form&＃39;: form})
4、处理删除菜单
class MenuDelView(View):def get(self,request,mid):Menu.objects.filter(id&＃61;mid).first().delete()return redirect(reverse(&＃39;rbac:menus_list&＃39;))
