django form表单验证，使用Ajax提交并返回提示信息（JSON传递数据）

直接上代码:

HTML，由Form插件自动生成input标签

    
    




    

        {% csrf_token %}
        
username:{{ user.username }}
        
gender:{{ user.gender }}
        

    
    
    

VIEWS代码

from django.shortcuts import render,redirect,HttpResponse
from django import forms
from django.forms import widgets
from app1 import models
import json

class AjaxForm(forms.Form):
    username = forms.CharField(
        required=True,
        min_length=3,
        error_messages={
            "min_length":"用户名输入不正确",
        }
    )
    gender = forms.BooleanField(
        widget=widgets.RadioSelect(choices=[(0,"男"),(1,"女"),]),
        required=False
    )

# Create your views here.
def ajaxForm(request):
    if request.method=="GET":
        user = AjaxForm()
        print("heheh ")
        return render(request,"AjaxForm.html",{"user":user})
    else:
        ret = {"status": "NG", "msg": None}
        af = AjaxForm(request.POST)
        if af.is_valid():
            print(af.cleaned_data)
            models.User.objects.create(**af.cleaned_data)
            ret["status"]="OK"
            return HttpResponse(json.dumps(ret))
        else:
            print("NG")
            ret["msg"] = af.errors
            return HttpResponse(json.dumps(ret))

MODELS数据库表：

from django.db import models

# Create your models here.
class User(models.Model):
    username = models.CharField(max_length=50)
    gender = models.BooleanField()

 

URL路由：

from django.contrib import admin
from django.urls import path
from app1 import views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('ajaxForm/', views.ajaxForm),
]
