１、基于类的方式重写登录：views.py:
from django.views.generic.base import View
class LoginView(View):
def get(self,request):
return render(request, "test/login.html", {})
def post(self,request):
user_name = request.POST.get("username", "")
pass_word = request.POST.get("password", "")
user = authenticate(username=user_name, password=pass_word)
if user is not None:
dj_login(request, user)
return render(request, "test/index.html", {})
else:
return render(request, "test/login.html", {"msg": "用户名或密码错误"})
users.py:
url(r'^login/$', LoginView.as_view(), name="login"),
2、用python变量描述文件路径，方便统一修改
<a style="color:white" class="fr registerbtn" href="{% url 'register' %}">注册</a>
<a style="color:white" class="fr loginbtn" href="/login/">登录</a>
{% load staticfiles %}
......
<link rel="stylesheet" type="text/css" href="/static/css/test/reset.css">
<link rel="stylesheet" type="text/css" href="/static/css/test/animate.css">
<link rel="stylesheet" type="text/css" href="{% static 'css/test/style.css'%}">
3、验证码
django-simple-captcha文档：http://django-simple-captcha.readthedocs.io/en/latest/usage.html#installation
urls.py:
urlpatterns = [
url(r'^captcha/', include('captcha.urls')),
]
settings.py:
INSTALLED_APPS = [
'captcha',
]
forms.py:
class RegisterForms(forms.Form):
email = forms.CharField(required=True)
password = forms.CharField(required=True, min_length=6)
captcha = CaptchaField()
views.py:
class RegisterView(View):
def get(self, request):
register_forms = RegisterForms()
return render(request, "test/register.html", {"register_forms": register_forms})
def post(self, request):
register_forms = RegisterForms(request.POST)
if register_forms.is_valid():
email = request.POST.get("email", "")
pass_word = request.POST.get("password", "")
if UserProfile.objects.filter(email=email):
return render(request, "test/register.html", {"msg": "邮箱已被注册"})
else:
user_profile = UserProfile()
user_profile.username = email
user_profile.email = email
user_profile.password = make_password(pass_word)
user_profile.save()
return render(request, "test/login.html", {})
else:
return render(request, "test/register.html", {"register_forms": register_forms})
register.html:
<form >
<div class="form-group marb20 ">
<label>邮 箱</label>
<input type="text" />
</div>
<div class="form-group marb8 ">
<label>密 码</label>
<input type="password" />
</div>
<div class="form-group marb8 captcha1 ">
<label>验 证 码</label>
{{ register_forms.captcha }}
</div>
<div class="error btns" ></div>
<div class="auto-box marb8">
</div>
<input class="btn btn-green" />
{% for key ,error in register_forms.errors.items %}{{ error }}{% endfor %}{{ msg }}
{% csrf_token %}
</form>
4、文件上传：
settings.py
MEDIA_URL = '/static/images/' MEDIA_ROOT = os.path.join(BASE_DIR, 'static/images/')
models.py:
image = models.ImageField(upload_to="course/%y/%m", verbose_name=u"封面图", max_length=100)
html显示：
{% for video in video_list%}
<div class="item">
<a href="">
<img src="{{ MEDIA_URL }}{{ video.image }}">
<p class="title">{{ video.name }}</p>
</a>
</div>
{% endfor %}
需要在settings.py:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')]
,
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
.......
'django.template.context_processors.media', # 配置html页面获取MEDIA_URL路径
],
},
},
]
