from django.shortcuts import render, HttpResponse
from app01.My_Forms import EmpForm
from app01 import models
from django.core.exceptions import ValidationError

Create your views here.

def add_emp(request):
if request.method == "GET":
form = EmpForm()
return render(request, "add_emp.html", {"form": form})
else:
form = EmpForm(request.POST)
if form.is_valid(): # 进行数据校验

        # 校验成功
        data = form.cleaned_data  # 校验成功的值，会放在cleaned_data里。
        data.pop('r_salary')
        print(data)

        models.Emp.objects.create(**data)
        return HttpResponse(
            'ok'
        )
        # return render(request, "add_emp.html", {"form": form})
    else:
        print(form.errors)    # 打印错误信息
        clean_errors = form.errors.get("__all__")
        print(222, clean_errors)
    return render(request, "add_emp.html", {"form": form, "clean_errors": clean_errors})

app01/urls.py 文件添加以下规则：

path('add_emp/', views.add_emp)
HTML 模版：

app01/add_emp.html
<!DOCTYPE html>
