如何保存在数据库上

Question

Django的

代码views.py：

from django.shortcuts import render
from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt
from home.models import Post

@csrf_exempt
def home(request):
    context = {'request_method': request.method}
    if request.method == 'POST':
        context['request_payload'] = request.POST.dict()
        post_data = dict(request.POST)
        print(post_data) 
        for key, value in post_data.items():
            for subvalue in value:
                print(key, subvalue)
                if key == 'name':
                    m = Post.name(subvalue)
                    m.save()

                if key == 'description':
                    print(subvalue)
                    p = Post.description(subvalue)
                    p.save()

    if request.method == 'GET':
        context['request_payload'] = request.GET.dict()
    return HttpResponse()

代码模型

from django.db import models

class Post(models.Model):
    name = models.CharField(max_length=150)
    description = models.CharField(max_length=150)

print(post_data)中的结果为{'name': ['luca', 'jeams'], 'description': ['all', 'all2']}. print(key, value)中的结果提取值是：

name Luca
name jeams
description all
description all2

我想将此数据保存在数据库中，但不起作用。 我能怎么做？

Answer 1

首先看一下文档 。 使用getlist获取具有相同名称的值的列表。 然后遍历它们并将数据保存在表中。

from django.shortcuts import render
from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt
from home.models import Post

@csrf_exempt
def home(request):
    context = {'request_method': request.method}
    if request.method == 'POST':
        context['request_payload'] = request.POST.dict()

        names = request.POST.getlist('name')
        descriptions = request.POST.getlist('description')

        for i in range(len(names)):
            post = Post.objects.create(name=names[i], description=descriptions[i])

    if request.method == 'GET':
        context['request_payload'] = request.GET.dict()
    return render(request, 'your_template_name_here', context)

将您的代码替换为post方法，如下所示：

if request.method == 'POST':
for ind, obj in enumerate(request.POST.getlist('name')):
    desc = request.POST.getlist('description')[ind]
    Post.object.create(name=obj, description=desc)

它会为你工作
