我有.load()像load_to.html页面中的jQuery 函数
$('#targetID').load('/load_from.html #bodyPart, script')
但是,这似乎不是从load_from.html页面加载JavaScript.有什么办法,我可以加载JavaScript.
使用django-socialregistration,收到错误消息:
Data truncated for column 'cur_url' at row 1
这里出了什么问题？
我已经使用 Apache+mod_wsgi 托管了 django 项目。我正在尝试通过子进程使用 git 命令来拉取更新，例如：
subprocess.check_output(['git', 'pull', 'origin', 'mybranch'])
但是，我收到如下错误：
Command '['git', 'pull', 'origin', 'mybranch']' returned non-zero exit status 128
当我通过浏览器调用这个函数时会出现这个问题。如果我subprocess.check_output(['git', 'pull', 'origin', 'mybranch'])从 python sell运行，则不会出错。它按预期完美运行。
Django有认证模块,效果很好.一旦用户进入,该信息被保存较长时间几乎没有问题.即使用户关闭浏览器会话也不会结束.实际上,我希望在用户关闭浏览器时该会话结束.
浏览器关闭后,是否有任何方式不再记住用户的登录信息

我叫Magento系列mymodule/class.我有两个表class,student在我的Magento数据库中.
班级表:
id clas_name
学生表:
id class_id student_name
class_id在student表中是id类表中的外键.
我想制作mymodule/class集合,以便sql如下所示:
select a.*, (select count(id) FROM studetn
WHERE class_id = a.id) as student_count
FROM class a
或者,我想mymodule/class从上面的sql.
怎么做任何建议？
我有以下代码行进行图像裁剪
im = Image.open('path/to/image.jpg')
outfile = "path/to/dest_img.jpg"
im.copy()
im.crop((0, 0, 500, 500))
im.thumbnail(size, Image.ANTIALIAS)
im.save(outfile, "JPEG")
但它似乎没有裁剪图像.我有更大的图像尺寸,例如2048 x 1536像素.
[编辑]
这也是解决方案,我自己无法回答这个问题,所以在这里添加答案.
实际上用新的处理程序裁剪返回图像,我意识到我犯了错误.我应该在新的处理程序中分配裁剪,如下所示
crop_img = im.crop((0, 0, 500, 500))
完整代码如下:
im = Image.open('path/to/image.jpg')
outfile = "path/to/dest_img.jpg"
im.copy()
crop_img = im.crop((0, 0, 500, 500))
crop_img.thumbnail(size, Image.ANTIALIAS)
crop_img.save(outfile, "JPEG")
请注意,在裁剪线之后,正在使用crop_img处理程序.
我正在尝试使用 AngularJS 上传图像。
我有这样的模型：
class Profile(models.Model):
user = models.OneToOneField(User)
name = models.CharField(max_length=20)
profile_picture = ImageField(upload_to=settings.MEDIA_ROOT, blank=True)
我有序列化程序：
class ProfileSerializer(serializers.ModelSerializer):
class Meta:
model = Profile
我有这样的视图：
class ProfileViewSet(viewsets.ModelViewSet):
queryset = Profile.objects.all()
serializer_class = ProfileSerializers
我的帖子转储是这样的：
