django 审核流程

基于django的多用户问题管理和流程管理系统
Django 没有内置的审核流程,但可以使用 Django 的信号系统和状态机来实现。以下是一个简单的审核流程实现步骤:
1. 定义状态机
定义一个状态机,包含审核过程中的所有状态和转换。例如,可以使用 `django-fsm` 库来定义状态机:
```python
from django_fsm import FSMIntegerField, transition
from django.db import models
class MyModel(models.Model):
STATUS_CHOICES = (
(0, '未审核'),
(1, '审核通过'),
(2, '审核未通过'),
)
status = FSMIntegerField(default=0, choices=STATUS_CHOICES)
@transition(field=status, source=0, target=1)
def approve(self):
pass
@transition(field=status, source=0, target=2)
def reject(self):
pass
```
2. 创建审核视图
创建一个审核视图,用于展示待审核的数据和审核表单。在审核表单中,可以添加一个 `status` 字段来更新审核状态:
```python
from django.views.generic import ListView, DetailView
from django.views.generic.edit import FormMixin
from django.urls import reverse_lazy
from django.contrib.auth.mixins import LoginRequiredMixin
from .models import MyModel
class MyModelListView(LoginRequiredMixin, ListView):
model = MyModel
template_name = 'mymodel_list.html'
class MyModelDetailView(LoginRequiredMixin, FormMixin, DetailView):
model = MyModel
template_name = 'mymodel_detail.html'
form_class = MyModelForm
success_url = reverse_lazy('mymodel_list')
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['form'] = self.get_form()
return context
def post(self, request, *args, **kwargs):
self.object = self.get_object()
form = self.get_form()
if form.is_valid():
self.object.status = form.cleaned_data['status']
self.object.save()
return self.form_valid(form)
else:
return self.form_invalid(form)
```
3. 监听状态机事件
在模型中添加一个方法来监听状态机事件,例如,当状态变为“审核通过”时,可以发送一个通知:
```python
from django_fsm import FSMIntegerField, transition
from django.db import models
from django.core.mail import send_mail
class MyModel(models.Model):
STATUS_CHOICES = (
(0, '未审核'),
(1, '审核通过'),
(2, '审核未通过'),
)
status = FSMIntegerField(default=0, choices=STATUS_CHOICES)
@transition(field=status, source=0, target=1)
def approve(self):
self.send_notification('通过')
@transition(field=status, source=0, target=2)
def reject(self):
self.send_notification('未通过')
def send_notification(self, result):
subject = f'您提交的 {self.__class__.__name__} 已审核{result}'
message = f'您提交的 {self.__class__.__name__} 已审核{result}'
send_mail(subject, message, 'from@example.com', [self.email])
```
4. 发送审核请求
最后,用户可以在前端页面上提交审核请求,例如,可以在列表视图中添加一个审核链接或按钮:
```html
{% for object in object_list %}
<a href="{% url 'mymodel_detail' pk=object.pk %}">审核</a>
{% endfor %}
```
在审核视图中,可以显示待审核数据的详细信息和审核表单,例如:
```html
<h1>{{ object }}</h1>
<p>Status: {{ object.status }}</p>
<form method="post">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">审核</button>
</form>
```
