我有自定义存储空间

import os
from django.core.files.storage import Storage


class AlwaysOverwriteFileSystemStorage(Storage):
    def get_available_name(self, name):
        """
        Directly Returns a filename that's 
        from what user input.
        """
        if self.exists(name):
    # Remove the existing file
        os.remove(name)
    # Return the input name as output
        return name

我想知道我应该在哪里放置他的AlwaysOverwriteFileSystemStorage.py文件以及settings.py如何定义DEFAULT_FILE_STORAGE

我的Django根文件夹是/ home/username/webapp

当我放DEFAULT_FILE_STORAGE = 'site.storage.AlwaysOverwriteFileSystemStorage',它返回一个

错误

导入存储模块site.storage时出错:"没有名为storage的模块"

我不熟悉Python/Django,任何帮助将不胜感激.谢谢.

我已经覆盖了list_display来显示这样的内联字段:

class opportunityAdmin(admin.ModelAdmin):
    list_display = ('name', 'Contact', 'Phone', 'Address', 'discovery_date', 'status' , 'outcome')
    search_fields = ['name', 'tags' , 'description']
    #readonly_fields = ('discovery_date','close_date')
    inlines = [account_contactInline, account_updateInline]

    def Contact(self, obj):
        return '<br/>'.join(c.account_poc for c in account_contact.objects.filter(opportunity=obj.id).order_by('id')[:1])

    def Phone(self, obj):
        return '<br/>'.join(c.account_phone for c in account_contact.objects.filter(opportunity=obj.id).order_by('id')[:1])

    def Address(self, obj):
        return '<br/>'.join(c.account_address for c in account_contact.objects.filter(opportunity=obj.id).order_by('id')[:1])

我的问题是,在Django admin中,内联字段标题的显示名称分别使用了函数名称:Contact,Phone和Address.实际上我想用自定义文本显示那些字段标题.我甚至想用中文来展示它们.我错过了什么？

我有一个标准的Django Admin页面,用于上传多个文件.我希望做到以下几点:

1. 直接上传一些文件
2. 一个文件需要在保存之前用AES加密(加密可以通过python或通过http到加密服务器完成.)
3. 一个zip文件需要解压缩,处理和重新打包.

我现在只有一个非常基本的管理页面.任何人都可以指出我从哪里开始的正确方向？请指出我需要修改哪个文件,因为我仍然不熟悉django.

只是一个简短的方向将不胜感激.谢谢.

从grappelli定制文档中,它建议:

    The sortable-field will not automatically be hidden
 (use a Hidden Input Widget if needed).

但是,我已经搜索了这么久,并且不知道什么是"隐藏输入小部件"以及如何将其实现为Django模型.这是我的代码:

     # models.py
class video(models.Model):
    category = models.ForeignKey(subCategory)
    index = PositionField('index')
    video_title = models.CharField(max_length=255, blank=True, null=True)
    video_desc = models.TextField(blank=True, null=True)
    main_img = S3EnabledImageField(upload_to='video_img', blank=True, null=True)
    small_img = S3EnabledImageField(upload_to='video_img', blank=True, null=True)
    mid_img = S3EnabledImageField(upload_to='video_img', blank=True, null=True)
    large_img = S3EnabledImageField(upload_to='video_img', blank=True, null=True)
    last_updated = models.DateField(auto_now=True)
    date_added = models.DateField()
    date_modified = models.DateField()
    date_published = models.DateField(blank=True, null=True)
    date_closed = models.DateField(blank=True, null=True)
    status = models.CharField(max_length=7,choices=STATUS_CHOICE)

    class Meta:
        ordering = ('index',) …

我是Django的新手.

我希望我的模型名称以中文显示,所以我在我的模型的元类中使用了verbose_name,代码如下:

#this models.py file is encoded in unicode

class TS_zone(models.Model):
    index = models.IntegerField()
    zone_name = models.CharField(max_length=50);
    zone_icon = models.ImageField(upload_to='zone_icon', null=True)
    is_active = models.NullBooleanField(blank=True, null=True)
    status = models.CharField(max_length=7,choices=SETTING_STATUS_CHOICES)
    class Meta:
        ordering = ('index',)
        verbose_name = u'????'
        verbose_name_plural = u'??????'

    def __unicode__(self):
        return self.zone_name

但是当我运行manage.py syncdb时,会抛出以下错误:

File "E:\pythonroot\myproject\..\myproject\myapp\models.py", line 19
SyntaxError: Non-ASCII character '\xe4' in file
E:\pythonroot\myproject\..\myproject\myapp\models.py on line 19, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

似乎manage.py无法处理我的verbose_name中的非ascii字符.我做错了什么？

谢谢.

我有一个int currentFontSize,我想与存储在C数组中的NSString进行比较,这里是代码.

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    static NSString* fontSizeName[] = 
    {
        @"14",
        @"18",
        @"22",
        @"26",
        @"30",
        @"34",
    };

    int fontSizeSegmentID;
    int currentFontSize = 22;

    NSString *val = [NSString stringWithFormat: @"%i", currentFontSize];
    NSString *val2 = @"22";
    NSLog(@"the current font size is %i", currentFontSize);
    NSLog(@"the current font Value1 is %i", val);
    NSLog(@"the current font Value2 is %i",val2);
    int i;
    for (i = 0; i < 6; i++) {

        NSLog(@"fontSizeNAme:%d",fontSizeName[i]);
        NSLog(@"val:%d",val); …
