使用django-import-export库，导入导出数据，支持csv、xls、json、html等格式

官网：

1、安装django-import-export

pip install django-import-export

2、配置settings.py

 

INSTALLED_APPS = (    'django.contrib.admin',    'django.contrib.auth',    'django.contrib.contenttypes',    'django.contrib.sessions',    'django.contrib.messages',    'django.contrib.staticfiles',    'customer',    'publisher',    'import_export',)

 

 

执行命令: python manage.py collectstatic

3、models.py 建立model

class Author(models.Model):    name = models.CharField(max_length=100)    def __unicode__(self):        return self.nameclass Category(models.Model):    name = models.CharField(max_length=100)    def __unicode__(self):        return self.nameclass Book(models.Model):    name = models.CharField('Book name', max_length=100)    author = models.ForeignKey(Author, blank=True, null=True)    author_email = models.EmailField('Author email', max_length=75, blank=True)    imported = models.BooleanField(default=False)    published = models.DateField('Published', blank=True, null=True)    price = models.DecimalField(max_digits=10, decimal_places=2, null=True, blank=True)    categories = models.ManyToManyField(Category, blank=True)    def __unicode__(self):        return self.name

 

4、在admin.py 创建Resource、对应的Admin

from import_export import resourcesfrom core.models import Bookfrom import_export.admin import ImportExportModelAdminclass BookResource(resources.ModelResource):    class Meta:        model = Book        export_order = ('id', 'name', 'author', 'author_email', 'imported', 'click', 'published', 'price', 'categories')@admin.register(Book)class BookAdmin(ImportExportModelAdmin):    list_display = ('name', 'author', 'author_email', 'imported', 'published', 'price', 'categories')    search_fields = ('name', 'author','published')    date_hierarchy = 'date'       resource_class = BookResource

 

export_order：设置导出字段的顺序

5、Django界面实现导入导出

 

 

 

自定义导出 方式 action 这种方式也推荐

import xlwt#导出Excelfrom django.http import StreamingHttpResponseclass AdminReport(admin.ModelAdmin):    actions = ["saveexecl"]                 # 自定义的action（导出到excel表格）    list_display = ("id",'offer','day_time', 'idfa', 'submit_result_text', 'callback_result_text')    # 显示的列    search_fields = ('day_time','callback_result_text')      # 可以搜索的字段    date_hierarchy = 'day_time'      # 按照日期显示    list_filter = ('offer',)         # 过滤条件    list_per_page = 500              # 每页显示500条，太多了可能会出现服务器崩掉的情况        def saveexecl(self,request,queryset):        Begin = xlwt.Workbook()        sheet = Begin.add_sheet("response")        cols = 0        for query in queryset:            # you need write colms                     # 好像有个方法可以一次性写入所有列，记不清了，只能用这种简单的方法去实现            sheet.write(cols,1,str(query.idfa))        # 写入第一列            sheet.write(cols,2,str(query.day_time))    # 写入第二列            sheet.write(cols,3,str(query.keyword))     # 写入第三列            cols += 1        Begin.save("%s" %(filename))        def file_iterator(filename,chuck_size=512):            with open(filename,"rb") as f:                while True:                    c = f.read(chuck_size)                    if c:                        yield c                    else:                        break        response = StreamingHttpResponse(file_iterator(filename))        response['Content-Type'] = 'application/octet-stream'        response['Content-Disposition'] = 'attachment;filename="{}"'.format("result.xls")        return response    saveexecl.short_description = "导出Excel"            # 按钮显示名字admin.site.register(Report, AdminReport)     # 注册到admin
