我正在将一个以前的Django REST API项目重建为GraphQL项目。我现在有疑问和突变工作正常。
我的大部分学习来自现有的Graphene-Django& amp; Graphene-Python代码示例。他们之间似乎存在许多不一致之处。
有人建议将GraphQL查询放在schema.py
中,而突变应放在mutation.py
中。
我认为更有意义的是让这两个文件保存各自的代码: - queries.py - mutation.py
我对Django& amp;虽然Python想要确保我没有违反任何约定。
对你的想法感兴趣!

还没有任何约定,因为GraphQL是REST的fairly new替代方法。因此,"惯例"在我们说话的那一刻创建。
但是,由于schema
是通用定义的术语,因此您可以将其重命名为queries
。
这是我的项目结构:
django_proj/
manage.py
requirements.txt
my_app/
__init__.py
migrations/
admin.py
schema/
__init__.py
schema.py # holds the class Query. The GraphQL endpoints, if you like
types.py # holds the DjangoObjectType classes
inputs.py # holds the graphene.InputObjectType classes (for defining input to a query or mutation)
mutations.py # holds the mutations (what else?!)
如果您愿意,可以将schema.py
(__init__
)重命名为queries.py
。这两个词之间没有太大的区别。

我非常喜欢nik_m的答案,我写了一些代码来从Django shell中生成模板结构。我想一遍又一遍地创建这些文件时强制执行一些一致性。我将代码放在这里以防其他人认为它有用。
import os
from django.conf import settings
def schema_setup(app_name):
"""
Sets up a default schema file structure.
"""
SCHEMA_DIRECTORY_NAME = 'schema'
app_directory = os.path.join(settings.PROJECT_DIR, app_name)
if not os.path.exists(app_directory):
raise Exception("Can't find app directory {}".format(app_directory))
schema_directory = os.path.join(app_directory, SCHEMA_DIRECTORY_NAME)
if os.path.exists(schema_directory):
raise Exception("Schema directory {} already exists.".format(schema_directory))
os.makedirs(schema_directory)
mutation_class = "{}Mutation".format(app_name.title())
query_class = "{}Query".format(app_name.title())
init_txt = "from .mutations import {}\nfrom .queries import {}\n".format(mutation_class, query_class)
fields_txt = "# Insert common fields here.\nimport graphene\n"
inputs_txt = "# Insert graphene.InputObjectType classes.\nimport graphene\n"
mutations_txt = "# Insert graphql mutations here.\nimport graphene\n\nclass {}(graphene.AbstractType):\n pass\n".format(mutation_class)
queries_txt = "# Insert graphql queries here.\nimport graphene\n\nclass {}(graphene.AbstractType):\n pass\n".format(query_class)
types_txt = "# Insert DjangoObjectType classes here.\nimport graphene\nfrom graphene_django.types import DjangoObjectType\n"
for fname, file_text in [("__init__.py", init_txt),
("fields.py", fields_txt),
("inputs.py", inputs_txt),
("mutations.py", mutations_txt),
("queries.py", queries_txt),
("types.py", types_txt),
]:
with open(os.path.join(schema_directory, fname), "w") as output_file:
output_file.write(file_text)
print("Created {}".format(fname))
从Django shell中,运行schema_setup("my_app")
注意:
PROJECT_DIR
PROJECT_DIR = os.path.dirname(os.path.abspath(__file__))
from my_app.schema import MyAppQuery, MyAppMutation
