小编ign*_*aga的帖子

我有一组我需要替换的字符串,但我需要保留字母的大小写.输入字和输出字的长度相同.

例如,如果我需要用"qwer"替换"abcd",那么应该发生以下情况:

"AbcD" translates to "QweR"
"abCd" translates to "qwEr"

等等.

现在我正在使用JavaScript replace,但大写字母在翻译时丢失了.

r = new RegExp( "(" + 'asdf' + ")" , 'gi' );
"oooAsdFoooo".replace(r, "qwer");

任何帮助,将不胜感激.

    )

class Person(models.db):
    """ A model to represet a person """
    name = models.CharField(max_length=200,
        help_text="The name of this person",
    )

资源:

class PictureResource(ModelResource):
    """ API Resource for the Picture model """
    people = fields.ToManyField(PersonResource, 'people', null=True,
        related_name="pictures", help_text="The people in this picture",
    )
class PersonResource(ModelResource):
    """ API Resource for the Person model """
    pictures = fields.ToManyField(PictureResource, 'pictures', null=True, …
