#user.save()
# return render(request, 'login.html', {'success': "you have successfully registered!"})
return redirect('login')
else:
return render(request, 'register.html', {'form': form})
方式一：
前端request.user.is_authenticated()判断当前用户是否登录
<form class="form-signin" role="form" method='post'>
<h3 class="form-signin-heading">Welcome!>
{% if request.user.is_authenticated %}
hihi: {{ request.user }} </br>
<a href="{% url 'log_out' %}">登出</a>
{% endif %}
</form>
方式二 将request.user.is_authenticated判断写入views视图再传入html中
@login_required
def index(request):
if request.user.is_authenticated(): # 判断用户是否已登录
user = request.user;
return render_to_response('index.html', locals())
<form class="form-signin" role="form" method='post'>
<h3 class="form-signin-heading">Welcome!>
欢迎登录！{{ user }}
<a href="{% url 'log_out' %}">登出</a>
</form>
