Django框架测试功能不工作

我一直停留在这个功能得到这个错误，我似乎不能解决，我仍然是新的编码。它给我错误的事情，我觉得我已经做了。
我有很多文件，但我会分享我最近刚刚更改的文件，我认为这一定是问题所在。
这是我的账户/views.py:

from django.shortcuts import render, redirect
from django.contrib.auth import authenticate, login
from django.urls import reverse
from .forms import LoginForm

def login_view(request):
    if request.method == "GET":
        form = LoginForm()
        return render(request, "accounts/login.html", {"form": form})
    elif request.method == "POST":
        form = LoginForm(request.POST)
        if form.is_valid():
            username = form.cleaned_data["username"]
            password = form.cleaned_data["password"]
            user = authenticate(request, username=username, password=password)
            if user is not None:
                login(request, user)
                return redirect(reverse("projects:list_projects"))
    return redirect(reverse("accounts:login"))

这是我的帐户/urls.py:

from django.urls import path
from . import views

app_name = "accounts"

urlpatterns = [
    path("login/", views.login_view, name="login"),
]

这是我的accounts/templates/accounts/login.html：

<!DOCTYPE html>
<html>
  <head>
    <title>Login</title>
  </head>
  <body>
    <main>
      <div>
        <h1>Login</h1>
      </div>
      <form method="post">
        {% csrf_token %} {{ form }}
        <button type="submit">Login</button>
      </form>
    </main>
  </body>
</html>

我读过我需要完成的事情的规则，感觉我已经达到了标准，但它给了我一个错误，好像我没有做到所有这些。
这是我得到的错误：

            200,
            msg="Login does not seem to work",
        )

以防万一这是我的主要跟踪器/urls.py:

from django.contrib import admin
from django.urls import path, include
from . import views

urlpatterns = [
    path("admin/", admin.site.urls),
    path(
        "projects/",
        include(("projects.urls", "projects"), namespace="projects"),
    ),
    path(
        "accounts/",
        include(("accounts.urls", "accounts"), namespace="accounts"),
    ),
    path("", views.redirect_to_projects, name="home"),
]

我在www.example.com中正确安装了所有应用程序settings.py
