1、从数据库提取数据展示到前端html页面中
if request.method =="GET":
var_dict={}
all_messages = Message.objects.all()
# 如果不为空
if all_messages:
message = all_messages[0]
var_dict = {"message": message}
return render(request, "message_form.html",var_dict)2、完整版views.py页面
from django.shortcuts import render
# Create your views here.
from apps.message_form.models import Message
def message_form(request):
if request.method =="GET":
var_dict={}
all_messages = Message.objects.all()
# 如果不为空
if all_messages:
message = all_messages[0]
var_dict = {"message": message}
return render(request, "message_form.html",var_dict)
if request.method == "POST":
name=request.POST.get("name","")
address = request.POST.get("address", "")
email = request.POST.get("email", "")
message_txt = request.POST.get("message", "")
message = Message()
message.name = name
message.address =address
message.email =email
message.message= message_txt
message.save()
return render(request, "message_form.html", {"message": message})
2、完整版前端页面
