具体的写法是
results = ServerInformation.objects.get(id = 1)#filter是queryset,没有_meta方法
allhost = ServerInformation._meta.get_all_field_names()#这句没错
vername = ServerInformation._meta.get_field('ServerType').verbose_name#这句也没错，S erverType是该模型的一个属性。
vervalue = ServerInformation._meta.get_field('ServerZone').default #即可获取到默认的值，话说你都懂得获取到verbose_name,怎么不会想到直接.default呢。
ps:
getattr(object, name[, default])
Return the value of the named attribute of object. name must be a string. If the string is the name of one of the object’s attributes, the result is the value of that attribute. For example,
getattr(x, 'foobar')
is equivalent to
x.foobar
. If the named attribute does not exist, default is returned if provided, otherwise AttributeError is raised.
看看怎么使用。
