无法在 Django 中执行视图操作

Question

我想了解为什么当我单击登录按钮时无法运行user_login 函数。我是django 的新手。谢谢

urls.py:

from django.urls import path
from iol_dash import views

urlpatterns = [
    path('', views.index, name='index'),
]

views.py：

from django.shortcuts import render
from iol import Service

def index(request):
    return render(request, 'index.html', {})

def user_login(request):
    username = request.POST.get('username')
    password = request.POST.get('password')
    service = Service()
    token = service.get_token(
        username=username,
        password=password
    )
    print(token)

index.html:

<form class="modal-content animate" method="post" action={{ views.user_login }}>
    {% csrf_token %}
    {{ form.as_p }}
    <div class="imgcontainer">
      <span onclick="document.getElementById('id01').style.display='none'" class="close" title="Close Modal">&times;</span>
    </div>
    <div class="container">
      <label for="username"><b>Username</b></label>
      <input type="text" placeholder="Enter Username" name="username" required>
      <label for="password"><b>Password</b></label>
      <input type="password" placeholder="Enter Password" name="password" required>
      <button type="submit">Login</button>

    </div>
</form>

您需要为每个视图定义一个 url。你的urls.py 应该是：

from django.urls import path
from iol_dash import views

urlpatterns = [
    path('', views.index, name='index'),
    path('login',views.user_login,name='user_login')
]

而你的index.html应该是这样的：

<form class="modal-content animate" method="post" action="{% url 'user_login' %}">
    {% csrf_token %}
    {{ form.as_p }}
    <div class="imgcontainer">
      <span onclick="document.getElementById('id01').style.display='none'" class="close" title="Close Modal">&times;</span>
    </div>
    <div class="container">
      <label for="username"><b>Username</b></label>
      <input type="text" placeholder="Enter Username" name="username" required>
      <label for="password"><b>Password</b></label>
      <input type="password" placeholder="Enter Password" name="password" required>
      <button type="submit">Login</button>

    </div>
</form>
