我正在尝试使用带有管理员图片上传的图片工具包。在我的编辑表单中,有宽度和高度的字段。我需要一种方法将这些值传递给image-kit的处理器。
但是我找不到方法......?

答案是:
Imagekit版本是开发版本(2,0,0,'alpha',1)
假设我们在图像模型admin.py
def getThumb(文件,实例): return [resize.ResizeToFill(width = instance.width,height = instance.height)]
类图像(媒体):
width = models.IntegerField(blank = True,null = True)
height = models.IntegerField(blank = True,null = True)
file = models.ImageField(upload_to='static/uploads/images/bigs')
### IMAGE-KIT we are passing a callable function as processors to ImageSpecField
thumbnail = ImageSpecField( processors = getThumb, image_field='file', format='JPEG', options={'quality': 90})
### override admin save function
def save(self, *args, **kwargs):
# Call the "real" save() method in the base class 'models.Model'
super(Image, self).save(*args, **kwargs)
test = Image.objects.all()[0]
test.thumbnail.width ### getting a property means completing upload of imagekit file
