Question

我想为我的网站动态创建一个css文件，当我上传新的导航项时，该文件会更新。我知道我需要覆盖导航模型的保存，文件上传到我的s3之后我可以调用一个函数来做一些动作，但我不知道如何动态创建文件然后上传它到同一个s3服务器，但位置不同。

from django.db import models
from django.forms import CheckboxSelectMultiple

import tempfile

from django.conf import settings

from django.core.files.base import ContentFile
from django.core.files.storage import default_storage as s3_storage
from django.core.cache import cache

from datetime import datetime

import Image, os
import PIL.Image as PIL
import re, os, sys, urlparse

def createDynamicCSS():
    #create then save a css file here
    #probably best to 'navigation/nav.css'

    #loop through all entries and create class for all of them
    navs = PrimaryNav.all()

    cssfile = ""
    for n in navs:
        string = "." + n.slug + " { ... }"
        cssfile += string

    #save cssfile to s3



class PrimaryNav(models.Model):
    title = models.CharField(max_length=200)
    slug = models.SlugField(max_length=200)

    active = models.BooleanField()

   #saves to s3 (s3 address + /icon/ )
   icon = models.ImageField(upload_to='icons')

    def save(self):
        super(PrimaryNav, self).save() # Call the "real" save() method
        createDynamicCSS()

...

我不知道从哪里开始。我打算尝试解析我在网络上看到的csv函数，但事实证明这太难了。请帮忙

Django将动态创建的文件保存到s3
