如何解决依赖于另一个领域的石墨烯Django字段

Question

是否可以使用一个字段的输出来生成另一个字段的输出来解析两个字段？例如，我需要使用访问令牌生成刷新令牌，但我不确定如何在刷新令牌解析程序中获取访问令牌。

class Tokens(graphene.ObjectType):
accessToken = graphene.String()
refreshToken = graphene.String()
def resolve_accessToken(self, info, **kwargs):
return "..."
def resolve_refreshToken(self, info, **kwargs):
return "..."

Answer 1

尝试添加一个方法来生成从刷新方法调用的访问令牌

class Tokens(graphene.ObjectType):
access_token = graphene.String()
refresh_token = graphene.String()
def get_access_token(self, info, **kwargs):
if not hasattr(self, '_access_token'):
# Do stuff to create access token, then stash to only create once
self._access_token = ...
return self._access_token
def resolve_access_token(self, info, **kwargs):
return self.get_access_token(info, **kwargs)
def resolve_refresh_token(self, info, **kwargs):
access_token = self.get_access_token(info, **kwargs)
# Do stuff to create and return refresh token ...

此外，您应该使用蛇大小写调用您的方法和字段，即access_token与accessToken
