Question

我有一个带有ImageField的模型和一个更改上传路径的函数

class Images(models.Model):
    def upload_path(self, filename):
        return os.path.join(settings.TOOLS_IMAGE_UPLOADS, self.get_artworkID(),
                            filename)

    image = models.ImageField(upload_to=upload_path)
    artworkID = models.IntegerField(null=True, blank=True)

    def __str__(self):
        if self.title == "" or not self.title:
            return str(self.image)
        return self.title

    def get_artworkID(self):
        if self.artworkID:
            return str(self.artworkID)
        return 'temp'

TOOLS_IMAGE_UPLOADS的值是

PROJECT_DIR = os.path.dirname(os.path.abspath(__file__))
BASE_DIR = os.path.dirname(PROJECT_DIR)
MEDIA_NAME_FOLDER = 'media'
MEDIA_ROOT = os.path.join(BASE_DIR, MEDIA_NAME_FOLDER)
TOOLS_IMAGE_UPLOADS = os.path.join(MEDIA_ROOT, 'uploads', 'images')

问题是通过Django admin或rest api可视化Image对象时返回的URL是错误的

路径返回： http://localhost:8000/media/webapp/artrights/media/uploads/images/temp/file.png

文件的真实路径： http://localhost:8000/media/uploads/images/temp/file.png

我做错了什么或者我只需要制作一个自定义函数来返回正确的路径？

Answer 1

upload_to可调用{/ 3}}应该return a path相对于MEDIA_ROOT，因为它会附加到TOOLS_IMAGE_UPLOADS。

我认为问题是MEDIA_ROOT已包含MEDIA_ROOT。

所以函数应该在def upload_path(self, filename): return os.path.join('uploads', 'images', self.get_artworkID(), filename)：

之后返回路径的一部分

df = read.table(text = "
x y z
1 2 3
1 2 3
1 2 3
2 3 NA
1 2 3
1 3 NA
", header= T)

library(tidyverse)

# get the column names of your dataset
names = names(df)

# get unique values after omitting rows with NAs
value = unlist(unique(na.omit(df)))

# create a dataset with names and values
# (this is the pattern you want to follow)
df3 = data.frame(names, value)


df %>%
  mutate(id = row_number()) %>%   # flag the row number
  gather(v,value,-id) %>%         # reshape
  na.omit() %>%                   # remove rows with NAs
  left_join(df3, by="value") %>%  # join info about your pattern
  select(-v) %>%                  # remove that column
  spread(names, value) %>%        # reshape
  select(-id)                     # remove row number

#    x  y z
# 1  1  2 3
# 2  1  2 3
# 3  1  2 3
# 4 NA  2 3
# 5  1  2 3
# 6  1 NA 3
