小编dem*_*mux的帖子

我知道这与这个问题有关,但我最关心的是这是否可能会混淆诸如保留的评论等内容.

import ruamel.yaml as yaml

yaml_str = """\
first_name: Art
occupation: Architect  # This is an occupation comment
about: Art Vandelay is a fictional character that George invents...
"""

data = yaml.load(yaml_str, Loader=yaml.RoundTripLoader)

# I'd like to extend CommentedMap so that I can do something like:
data.insert(1, 'last_name', 'Vandelay')

print(yaml.dump(data, Dumper=yaml.RoundTripDumper))

first_name: Art
last_name: Vandelay
occupation: Architect  # This is an occupation comment
about: Art Vandelay is a fictional character that George invents...

first_name: …

我有一个模型,其中缩略图宽度在父对象(ForeignKey)之间变化.我需要能够将此信息提供给imagekit处理器.这就是我所拥有的:

class Wall(models.Model):
    #...
    width = models.SmallIntegerField(null=True, blank=True)
    #...


class Poster(models.Model):
    wall = models.ForeignKey(Wall, related_name='posters')
    #...
    original_image = models.ImageField(upload_to=upload_image_to)

    def __init__(self, *args, **kwargs):
        self.thumbnail = ImageSpecField([
                Adjust(contrast=1.2, sharpness=1.1),
                SmartResize(height=163, width=self.wall.width)
            ],
            image_field='original_image', format='PNG'
        )

        super(Poster, self).__init__(*args, **kwargs)
    #...

但是,如果我这样做,没有任何反应,甚至没有生成缩略图网址.

以下将导致此异常:
AttributeError:'ForeignKey'对象没有属性'width'

class Poster(models.Model):
    wall = models.ForeignKey(Wall, related_name='posters')
    #...
    original_image = models.ImageField(upload_to=upload_image_to)

    thumbnail = ImageSpecField([
            Adjust(contrast=1.2, sharpness=1.1),
            SmartResize(height=163, width=wall.width)
        ],
        image_field='original_image', format='PNG'
    )
    #...

Kaniko 将图像上传到 ECR，但无法上传图层缓存。

怎么了？
我该如何修复它？

.gitlab-ci.yml

.backend:
  variables:
    AWS_PAGER: ""
    AWS_DEFAULT_REGION: eu-west-1
    RUNNER_IMAGE: ${ECR_REGISTRY}/${ECR_IMAGE}:latest

错误 Kaniko 日志中的相关行：

我想在我的表单中选择这些字段但是......

错误:

{"name":["This field may not be blank."],"email":["This field may not be blank."]}

串行:

class StudentSerializer(ModelSerializer):
    name = CharField(read_only=False, required=False, allow_null=True)
    user = StudentUserSerializer(read_only=True)
    invite = StudentInviteSerializer(read_only=True)

    email = CharField(read_only=False, required=False, allow_null=True)

    class Meta:
        model = Student
        fields = ('id', 'name', 'user', 'invite', 'email')
