我现在正在学习DRF，对此many = True代码有些困惑。它有什么作用？还是什么意思？

例子1

class AlbumSerializer(serializers.ModelSerializer):
    tracks = serializers.RelatedField(many=True)

    class Meta:
        model = Album
        fields = ('album_name', 'artist', 'tracks')

例子2

class UserList(generics.ListCreateAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer
    permission_classes = (IsAdminUser,)

    def list(self, request):
        # Note the use of `get_queryset()` instead of `self.queryset`
        queryset = self.get_queryset()
        serializer = UserSerializer(queryset, many=True)
        return Response(serializer.data)

我是 Django 测试的新手，所以尝试了基本的测试代码。但它在第二个测试类中显示一个错误

测试文件

from django.test import TestCase,Client
from .views import PostList
from django.urls import resolve


class SmokeTest2(TestCase):
    def test_math(self):
        self.assertEqual(1+1,2)

class HomePageTest(TestCase):
    def test_root_url_resolves_to_home_page_view(self):
        found = resolve('/')
        print({'found':found})
        self.assertEqual(found.func(), PostList)

视图.py

class PostList(ListView):
    model = Post
    template_name = 'home.html'

网址.py

urlpatterns = [
    path('',views.PostList.as_view(),name ='list'),
]

当我打印found它显示 o/p

{'found': ResolverMatch(func=blog.views.PostList, args=(), kwargs={}, url_name=list, app_names=[], namespaces=[])}

但我仍然收到此错误

(blog_env) PS D:\django\blog_env\mysite> python manage.py test

我想制作一个像这样的注册表，用户可以在其中输入用户名，电子邮件，密码，确认密码并检查条款和条件框以进行注册。但我不知道如何为复选框创建模型行，以便根据其输入我将允许或禁止用户注册。

模型.py

class registeration(models.Model):
    username = models.CharField(max_length=100)
    email = models.EmailField()
    password = models.CharField(max_length=100)
    confirm_pasword = models.CharField(max_length=100)


    def __str__(self):
        return self.username

我正在使用一个 Excel 工作表，它总共有 999 行，其中 20 行是数据填充行，其他行是空的。

所以当我打印 max_rows 时，它给了我 999 个数字，而不是 20 个数字！我正在关注本教程 - openpyxl 教程

wb = openpyxl.load_workbook(path)
s = wb.active
print(s.max_row)

def resume_edit(request, r_id):

    r = Resume.get.object(pk=r_id)
    resume = ResumeModelForm(instance=r)

    resume.fields['email'].widget.attrs['readonly'] = True 

    return render(request, 'resumes/resume.html', context)

我试图这样做但它不起作用，我知道如何在 Forms.py 中做到这一点，但我想知道它可能与否？

我使用 Django 2.0

class ApiLoginView(TemplateView):
    template_name = 'index.html'

    def post(self,request):
        email = request.POST.get('Email')
        password = request.POST.get('Password')
        print(email)
        print(password)

        API_KEY = GetAPIkey().api_key_token()
        API_URL = GetAPIurl().api_url_token()
        parameter = {
            'authToken':API_KEY,
            'email':email,
            'password':password,
        }
        url = '{}{}'.format(API_URL,'/rest/storeLogin')
        r = requests.post(url = url, params=parameter)
        print(r.url)
        print(request.user)
        return HttpResponse(r)

我正在尝试从request.POST方法获取数据,但每次打印电子邮件和密码时它都会向我发送NONE值.我哪里错了？我在做ajax通话错了吗？当我使用表单submi进行ajax调用它工作正常但现在我使用按钮单击进行ajax调用.

<form class="my-login-form"  id="sanjh_login_form" method="post" url="/login">
                                  {% csrf_token %}
                                <div id="login-data"></div>

                                <div class="field-wrap">
                                <input id='id_login-email' type="email" name="Email" required autocomplete="off" placeholder="Email Id">
                              </div>
                                <div class="field-wrap">
                                <input id='id_login-password' type="password" name="Password" required autocomplete="off" placeholder="Password">
                              </div>
                                  <button id="login-btn" type="button" class="button button-block" >Login</button>
                                <div …
