Graphene-Django Filenaming Conventions

标签: python django graphql graphene-python

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:

  • 这假设您在PROJECT_DIR
  • 等设置中设置了PROJECT_DIR = os.path.dirname(os.path.abspath(__file__))
  • 在您的顶级架构中,导入为from my_app.schema import MyAppQuery, MyAppMutation
  • 我来回"查询"与"查询"和"突变" vs"突变" - 截至目前,石墨烯文件并不一致
