if request.user.is_anonymous():
....
is_anonymous()方法上有@Property
所以不能这样调用
也不是什么大问题,不过如果书卖的好,以后再版时改一下,严谨一点好。
$('#btnCrop').on('click', function(){
//alert("图片上传喽");
$.ajax({
url: '{% url "account:my_image" %}',
type: 'POST',
data: {"img": img},
success: function(e){
location.href= "{% url 'account:my_information' %}" },
});
});
photo=models.ImageField(max_length=15000,blank=True)
个人信息页面显示的图片只是剪裁图片页面所剪裁图片的的一小部分
源码2.0中的Except语句缺少错误类型, 这容易给后期代码出错找错误带来麻烦, 建议补充相应的错误类型, 方便读者编程查错
<script type="text/javascript" src= "{% static 'js/csrf.js'%}"></script>
$('#btnCrop').on('click', function(){
//alert("图片上传喽");
$.ajax({
url: '{% url "account:my_image" %}',
type: 'POST',
data: {"img": img},
success: function(e){
location.href= "{% url 'account:my_information' %}" },
});
});
按照教程, 但是点击OK后仍然不能提交
齐老师,您好,在django2.0中,展示个人信息这个章节中,按书中的例子输入代码,用get()会一直提示书中的那个错误,在网上百度了也没有找到解决方法以,求老师指点
path('login/', auth_views.login, name='user_login'),
path('new-login/', auth_views.login, {'template_name': 'account/login.html'}, name='user_login'),
path('logout/', auth_views.logout, {'template_name': 'account/logout.html'}, name='user_logout'),
path('register/', views.register, name='user_register'),
path('password-change/', auth_views.password_change, {"post_change_redirect":"/account/password-change-done", 'template_name': 'account/password_change_form.html'}, name='password_change'),
path('password-change-done/', auth_views.password_change_done, {'template_name': 'account/password_change_done.html'}, name='password_change_done'),
path('password-reset/', auth_views.password_reset, {"template_name":"account/password_reset_form.html", "email_template_name":"account/password_reset_email.html", "subject_template_name":"account/password_reset_subject.txt", "post_reset_redirect":"/account/password-reset-done"}, name="password_reset"),
path('password-reset-done/', auth_views.password_reset_done, {"template_name":"account/password_reset_done.html"}, name="password_reset_done"),
path('password-reset-confirm///', auth_views.password_reset_confirm, {"template_name":"account/password_reset_confirm.html", "post_reset_redirect":"/account/password-reset-complete"}, name="password_reset_confirm"),
path('password-reset-complete/', auth_views.password_reset_complete, {"template_name":"account/password_reset_complete.html"}, name="password_reset_complete"),
上述代码中的内置方法,已经在django2.0不适用了,代码需修改,从以下模块中导入内置方法
from django.contrib.auth.views import LoginView
url中需修改为以下代码
path('login/', LoginView.as_view(), name='user_login'), # django内置登录
path('new-login/', LoginView.as_view(), {'template_name': 'account/login.html'}, name='user_login'),
齐老师,能在github上更新一下django2.0 当中的代码,有一些有错误,没有更正过来

您在书中关于缩略图的使用中使用了 sudo 管理员权限进行迁移, 然而在实际开发中似乎大家倾向于使用虚拟环境(Virtualenv等)进行开发
如此, 若使用sudo命令操作, 则使用的是系统的Python, 二者的库并不相同. 不知道您使用sudo的用意是什么?
我在实际操作中还是没有使用sudo, 目前得到的结果与书中是一致的.
文件 ./blog/views.py里,blog_title()函数中 blogs = BlogArticles.objects.all(),提示Class 'BlogArticles' has no 'objects' member",请教下这个怎么解决下?
齐老师,您好!
我用内置的方法重置密码的时候,向qq邮箱发送邮件时,网页显示已经发送了,但是qq邮箱并没有收到,肯能是什么原因啊
