[英]Graphene-django returns null node instead of just node field
I am facing a strange problem with graphene and Django. 我面临着石墨烯和Django的奇怪问题。 The documentation seems to lack a solution and I couldn't figure out what I'm doing wrong.
该文档似乎缺乏解决方案,我无法弄清楚自己在做什么错。
I have the following models: 我有以下型号:
Class Sentence(models.Model):
ref = models.CharField(max_length=30, primary_key=True)
body = models.TextField(default=None)
Class Summary(models.Model):
sentence = models.ForeignKey(Sentence, on_delete=models.CASCADE)
text = models.TextField(default=None)
(Each sentence can have multiple summaries) (每个句子可以有多个摘要)
And the following schema: 以及以下架构:
Class SentenceType(DjangoObjectType):
class Meta:
model = models.Sentence
filter_fields = {"ref": ["exact"]}
interfaces = (graphene.Node, )
Class SummaryType(DjangoObjectType):
class Meta:
model = models.Summary
filter_field = {"text": ["icontains"]}
interfaces = (graphene.Node, )
Class Query(graphene.ObjectType):
all_sentences = DjangoFilterConnectionField(SentenceType)
sentence = graphene.Field(SentenceType, ref=graphene.string(), body=graphene.string())
all_summary = all_provvedimenti = DjangoFilterConnectionField(SummaryType)
summary = graphene.field(SummaryType, id=graphene.Int(), text=graphene.string())
def resolve_all_summaries(self, context, **kwargs):
return models.Summary.objects.all()
It can occur that there is one or more summaries in my database with no corresponding sentence. 我的数据库中可能有一个或多个摘要,但没有相应的句子。
Now, when I query 现在,当我查询
{
allSummaries{
edges{
node{
text
sentence{
ref
}
}
}
}
}
If the the sentence exists for the summary, no problem at all. 如果该句子用于总结,则完全没有问题。 But if there is no corresponding sentence I get:
但是如果没有相应的句子,我会得到:
"errors": [
{
"message": "Sentence matching query does not exist.",
"locations": [
{
"line": 6,
"column": 9
}
]
}
],
...,
...,
"data":[
...,
{
"node": null
},
{
"node":{
"text": "blah blah blah sentence summary"
"sentence": {
"ref": "sentence_reference"
}
}
}
{
"node": null
},
...,
]
Naturally, the output I would expect is that whenever a corresponding sentence does not exist for a summary node it would still give me back the text of the summary and "sentence": null or []. 自然,我期望的输出是,只要摘要节点不存在相应的句子,它仍会给我返回摘要和“句子”的文本:null或[]。
I had no luck in the documentation or google. 我在文档或Google方面没有运气。 Seems I am the only one having this issue.
似乎我是唯一遇到此问题的人。 I can't understand whether I am making some mistake in Django, graphene or it is just a bug.
我不明白我是在Django,graphene中犯了错误还是只是一个错误。
Any suggestions? 有什么建议么?
change the all_summary
variable in this line 更改此行中的
all_summary
变量
all_summary = all_provvedimenti = DjangoFilterConnectionField(SummaryType)
to allSummaries
对所有
allSummaries
and then change your function name in 然后在中更改函数名称
def resolve_all_summaries(self, context, **kwargs):
to resolve_allSummaries
as well 以及
resolve_allSummaries
then you can query with: 然后您可以查询:
{
allSummaries{
edges{
node{
text
sentence{
ref
}
}
}
}
}
all three of those identifiers refer to the same thing and therefor need to match 这些标识符中的所有三个都指同一事物,因此需要匹配
