Django学生管理系统添加学生时，报错Not Found: /POST

最近在学习Django，跟着视频写了一个学生系统，主要是增删改查操作，界面丑的一匹

1.url.py

from django.contrib import admin
from django.urls import path,re_path
from app01.views import classes
from app01.views import teachers
from app01.views import students

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path('get_classes.html$', classes.get_classes),
    re_path('add_classes.html$', classes.add_classes),
    re_path('update_classes.html$', classes.update_classes),
    # re_path('edit_classes.html$', classes.edit_classes),
    re_path('del_classes.html$', classes.del_classes),
    re_path('get_students.html$', students.get_students),
    re_path('add_students.html$', students.add_students),
]

2.models.py

from django.db import models

# Create your models here.
class Classes(models.Model):
    title = models.CharField(max_length=32)
    m =models.ManyToManyField("Teachers")


class Teachers(models.Model):
    name = models.CharField(max_length=32)


class Students(models.Model):
    username = models.CharField(max_length=32)
    age = models.IntegerField()
    gender = models.BooleanField()
    cs = models.ForeignKey(Classes,on_delete=models.CASCADE,)

导致报错的原因：用户名和年龄的input标签少了一斜杠
