python - django 导入_导出 |数据未从数据库导出

Question

我正在使用 Django-import_export 导出数据。我使用了下面给出的代码，但无法正常工作。它仅导出脱水数据而不是给定字段。

class MemberResource(resources.ModelResource):
    Brand=Field()
    class meta:
        model = model
        fields=('title','Brand')
    def dehydrate_Brand(self, obj):
        return str(obj.Brand.title)

class modelAdmin(ImportExportModelAdmin):
    resource_class = MemberResource
    list_display=['title','Model_code','Chipset','chipset_description','Brand','categories']
    search_fields = ['title','Model_code','Chipset',]
    fields=('title','Model_code','Chipset','chipset_description','image','Brand','Cat')
admin.site.register(model,modelAdmin)

Answer 1

Meta 的名称子类是<b>M</b>eta ，不是<s>m</s>eta ，所以ModelResource应该看起来像:

class MemberResource(resources.ModelResource):
    Brand=Field()
    
    class <strong>Meta</strong>:
        model = Member
        fields = ('title','Brand')
    
    def dehydrate_Brand(self, obj):
        return str(obj.Brand.title)
