Python 如何从Django管理员上传多个文件？

我想在Django管理员中上传多个文件，而不必放置多个文件字段。用户能够以简单的方式管理文件；删除或更改每个上载的文件，但同时上载多个

我认为可行的解决方案是使用几个文件字段，但问题是，我不知道用户将上载多少文件

def case_upload_location(instance, filename):
    case_name = instance.name.lower().replace(" ", "-")
    file_name = filename.lower().replace(" ", "-")
    return "casos/{}/{}".format(case_name, file_name)


class Case(models.Model):
    name            = models.CharField(max_length=250)
    observations    = models.TextField(null = True, blank = True)
    number_folder    = models.CharField('Folder', max_length=250)


    file1 = models.FileField('file 1', upload_to=case_upload_location, null = True, blank = True)
    file2 = models.FileField('file 2', upload_to=case_upload_location, null = True, blank = True)
    file3 = models.FileField('file 3', upload_to=case_upload_location, null = True, blank = True)
    file4 = models.FileField('file 4', upload_to=case_upload_location, null = True, blank = True)

最终目标

要上载多个文件（用户需要逐个删除或更改，但一次上载所有文件）。

看起来您需要一个多外键关系，从“案例文件”模型到您定义的“案例”模型

型号.py

from django.db import models

def case_upload_location(instance, filename):
    case_name = instance.name.lower().replace(" ", "-")
    file_name = filename.lower().replace(" ", "-")
    return "casos/{}/{}".format(case_name, file_name)

class Case(models.Model):
    # datos del caso
    name = models.CharField('Nombre', max_length=250)
    observations = models.TextField('Observaciones', null = True, blank = True)
    number_folder = models.CharField('Numero de Carpeta', max_length=250)

class CaseFile(models.Model):
    case = models.ForeignKey(Case, on_delete=models.CASCADE) # When a Case is deleted, upload models are also deleted
    file = models.FileField(upload_to=case_upload_location, null = True, blank = True)

from django.contrib import admin
from .models import Case, CaseFile

class CaseFileAdmin(admin.StackedInline):
    model = CaseFile

@admin.register(Case)
class CaseAdmin(admin.ModelAdmin):
    inlines = [CaseFileAdmin]

@admin.register(CaseFile)
class CaseFileAdmin(admin.ModelAdmin):
    pass

然后，您可以添加StackedLine管理表单，将案例文件直接添加到给定案例中

admin.py

from django.db import models

def case_upload_location(instance, filename):
    case_name = instance.name.lower().replace(" ", "-")
    file_name = filename.lower().replace(" ", "-")
    return "casos/{}/{}".format(case_name, file_name)

class Case(models.Model):
    # datos del caso
    name = models.CharField('Nombre', max_length=250)
    observations = models.TextField('Observaciones', null = True, blank = True)
    number_folder = models.CharField('Numero de Carpeta', max_length=250)

class CaseFile(models.Model):
    case = models.ForeignKey(Case, on_delete=models.CASCADE) # When a Case is deleted, upload models are also deleted
    file = models.FileField(upload_to=case_upload_location, null = True, blank = True)

from django.contrib import admin
from .models import Case, CaseFile

class CaseFileAdmin(admin.StackedInline):
    model = CaseFile

@admin.register(Case)
class CaseAdmin(admin.ModelAdmin):
    inlines = [CaseFileAdmin]

@admin.register(CaseFile)
class CaseFileAdmin(admin.ModelAdmin):
    pass

为什么不建立一个单独的模型，它只包含一个文件字段，可以用FK链接到

案例

&您可以通过admin添加内联线来添加文件
