Overview

Reusable utilities for FastAPI

Documentation: https://fastapi-utils.davidmontague.xyz

Source Code: https://github.com/dmontagu/fastapi-utils

FastAPI is a modern, fast web framework for building APIs with Python 3.6+.

But if you're here, you probably already knew that!

Features

This package includes a number of utilities to help reduce boilerplate and reuse common functionality across projects:

Class Based Views: Stop repeating the same dependencies over and over in the signature of related endpoints.
Response-Model Inferring Router: Let FastAPI infer the response_model to use based on your return type annotation.
Repeated Tasks: Easily trigger periodic tasks on server startup
Timing Middleware: Log basic timing information for every request
SQLAlchemy Sessions: The FastAPISessionMaker class provides an easily-customized SQLAlchemy Session dependency
OpenAPI Spec Simplification: Simplify your OpenAPI Operation IDs for cleaner output from OpenAPI Generator

It also adds a variety of more basic utilities that are useful across a wide variety of projects:

APIModel: A reusable pydantic.BaseModel-derived base class with useful defaults
APISettings: A subclass of pydantic.BaseSettings that makes it easy to configure FastAPI through environment variables
String-Valued Enums: The StrEnum and CamelStrEnum classes make string-valued enums easier to maintain
CamelCase Conversions: Convenience functions for converting strings from snake_case to camelCase or PascalCase and back
GUID Type: The provided GUID type makes it easy to use UUIDs as the primary keys for your database tables

See the docs for more details and examples.

Requirements

This package is intended for use with any recent version of FastAPI (depending on pydantic>=1.0), and Python 3.6+.

Installation

pip install fastapi-utils

[BUG] Unable to resolve multiple handlers for the same HTTP action but with different routes

Describe the bug

I have a BlogCBV where I have a few handler functions, three of which are GETs:

get_drafts
get_blogs
get_blog

get_drafts has a path of blogs/drafts get_blog has a path of blogs/{blog_id}

However, when I want to reach the endpoint get_drafts by hitting blogs/drafts, get_blog will be reached instead.

Below is the code snippet:

# blog.py

from typing import List

from fastapi import APIRouter, Depends, Path
from fastapi_utils.cbv import cbv
from fastapi_utils.inferring_router import InferringRouter
from sqlalchemy.orm import Session

from app.api.utils.db import get_db
from app.api.utils.security import get_current_active_user
from app.db import crud
from app.db.orm.blog import Blog
from app.db.orm.user import User
from app.dtos.blog import BlogForDetail, BlogForEdit, BlogForList, BlogForNew
from app.dtos.msg import Msg

router = APIRouter()

BLOG_DEFAULT_PAGE_SIZE = 10


router = InferringRouter()


@cbv(router)
class BlogCBV:
    session: Session = Depends(get_db)
    current_user: User = Depends(get_current_active_user)

    @router.get("/drafts")
    def get_drafts(
        self, *, page: int = 1, page_size: int = BLOG_DEFAULT_PAGE_SIZE,
    ) -> List[BlogForList]:
        """
        Retrieve blog drafts for the current user.
        """
        drafts = crud.blog.get_drafts(
            self.session, author=self.current_user, page=page, page_size=page_size
        )
        return [BlogForList.from_orm(draft) for draft in drafts]

    @router.get("/{blog_id}")
    def get_blog(
        self, *, blog_id: int = Path(..., title="The ID of the blog to be returned."),
    ) -> BlogForDetail:
        """
        Retrieve a published blog.
        """
        blog = crud.blog.get(self.session, id=blog_id)
        return BlogForDetail.from_orm(blog)

    @router.get("/",)
    def get_blogs(
        self, *, page: int = 1, page_size: int = BLOG_DEFAULT_PAGE_SIZE,
    ) -> List[BlogForList]:
        """
        Retrieve published blogs by all users.
        """
        blogs = crud.blog.get_multi(self.session, page=page, page_size=page_size)
        return [BlogForList.from_orm(blog) for blog in blogs]

# api.py

from fastapi import APIRouter

from app.api.api_v1.endpoints import blogs, login, users, utils, profile

api_router.include_router(blogs.router, prefix="/blogs", tags=["blogs"])

# main.py

app = FastAPI(title=config.PROJECT_NAME, openapi_url="/api/v1/openapi.json")
app.include_router(api_router, prefix=config.API_V1_STR)

Expected behavior get_drafts should be correctly resolved and reached.

Environment:

OS: Linux (Fedora 31)
FastAPI Utils, FastAPI, and Pydantic versions:

0.1.1
0.49.0
             pydantic version: 1.4
            pydantic compiled: True
                 install path: /usr/local/lib/python3.7/site-packages/pydantic
               python version: 3.7.4 (default, Sep 12 2019, 15:40:15)  [GCC 8.3.0]
                     platform: Linux-5.5.5-200.fc31.x86_64-x86_64-with-debian-10.1
     optional deps. installed: ['email-validator', 'devtools']

Python version: 3.7.4

Additional context In my test:

    def test_get_all_my_drafts(self, session, test_user_token_headers):
        batch_create_random_blogs(session, is_published=False, num=3)
        batch_create_random_blogs(session, is_published=True, num=2)
        url = app.url_path_for("get_drafts")

        r = client.get(url, headers=test_user_token_headers)
        drafts = r.json()

        debug(drafts)

        assert r.status_code == 200
        assert len(drafts) == 3

The url can be correctly resolved: url: '/api/v1/blogs/drafts'

[BUG]/[FEATURE] multiple path's on the same method results in errors

Not quite clear to me if this is a bug or a feature request as I may be doing something out of the ordinary.

Using class based views, my tests return errors using methods (inside cbv) that have multiple path decorators attached to them. When using vanilla FastAPI without cbv the tests pass.

To Reproduce

Credit to @smparekh for the demo below, which I modified slightly to show the issue.

Simple main.py app:

from fastapi import FastAPI, APIRouter

from fastapi_utils.cbv import cbv

router = APIRouter()


fake_items_db = [{"item_name": "Foo"}, {"item_name": "Bar"}, {"item_name": "Baz"}]


@cbv(router)
class RootHandler:
    @router.get("/items/?")
    @router.get("/items/{item_path:path}")
    @router.get("/database/{item_path:path}")
    def root(self, item_path: str = None, item_query: str = None):
        if item_path:
            return {"item_path": item_path}
        elif item_query:
            return {"item_query": item_query}
        else:
            return fake_items_db


app = FastAPI()
app.include_router(router)

simple test_main.py

from .main import router


from starlette.testclient import TestClient
from .main import fake_items_db

client = TestClient(router)


def test_item_path():
    resp = client.get("items/Bar")
    assert resp.status_code == 200
    assert resp.json() == {"item_path": "Bar"}


def test_item_query():
    resp = client.get("items/?item_query=Bar")
    assert resp.status_code == 200
    assert resp.json() == {"item_query": "Bar"}


def test_list():
    resp = client.get("items/")
    assert resp.status_code == 200
    assert resp.json() == fake_items_db


def test_database():
    resp = client.get("database/")
    assert resp.status_code == 200
    assert resp.json() == fake_items_db

How get application state in periodic task?

I need to get app.state to retrieve the Postgres pool driver in my periodic task. Because task repeating every 5 sec.

How can I do this with the fastapi routing case (when app.state is available only in request object)?

In this example, I'm forced to create gspread and asyncpg connections every 5 seconds this is a terrible decision.

orm

[orm] [bug] Removed very old warning that states that passive_deletes is not intended for many-to-one relationships. While it is likely that in many cases placing this parameter on a many-to-one relationship is not what was intended, there are use cases where delete cascade may want to be disallowed following from such a relationship.

This change is also backported to: 1.3.24

References: #5983

[orm] [bug] Fixed issue where the process of joining two tables could fail if one of the tables had an unrelated, unresolvable foreign key constraint which would raise _exc.NoReferenceError within the join process, which nonetheless could be bypassed to allow the join to complete. The logic which tested the exception for significance within the process would make assumptions about the construct which would fail.

This change is also backported to: 1.3.24

References: #5952

[orm] [bug] Fixed issue where the _mutable.MutableComposite construct could be placed into an invalid state when the parent object was already loaded, and then covered by a subsequent query, due to the composite properties' refresh handler replacing the object with a new one not handled by the mutable extension.

This change is also backported to: 1.3.24

References: #6001

[orm] [bug] Fixed regression where the _orm.relationship.query_class parameter stopped being functional for "dynamic" relationships. The AppenderQuery remains dependent on the legacy _orm.Query class; users are encouraged to migrate from the use of "dynamic" relationships to using _orm.with_parent() instead.

References: #5981

[orm] [bug] [regression] Fixed regression where _orm.Query.join() would produce no effect if the query itself as well as the join target were against a _schema.Table object, rather than a mapped class. This was part of a more systemic issue where the legacy ORM query compiler would not be

orm

[orm] [bug] Fixed bug where using with_polymorphic() as the target of a join via RelationshipComparator.of_type() on a mapper that already has a subquery-based with_polymorphic setting that's equivalent to the one requested would not correctly alias the ON clause in the join.

References: #5288

[orm] [bug] Fixed issue in the area of where loader options such as selectinload() interact with the baked query system, such that the caching of a query is not supposed to occur if the loader options themselves have elements such as with_polymorphic() objects in them that currently are not cache-compatible. The baked loader could sometimes not fully invalidate itself in these some of these scenarios leading to missed eager loads.

References: #5303

[orm] [bug] Modified the internal "identity set" implementation, which is a set that hashes objects on their id() rather than their hash values, to not actually call the __hash__() method of the objects, which are typically user-mapped objects. Some methods were calling this method as a side effect of the implementation.

References: #5304

[orm] [bug] An informative error message is raised when an ORM many-to-one comparison is attempted against an object that is not an actual mapped instance. Comparisons such as those to scalar subqueries aren't supported; generalized comparison with subqueries is better achieved using ~.RelationshipProperty.Comparator.has().

References: #5269

[orm] [usecase] Added an accessor ColumnProperty.Comparator.expressions which provides access to the group of columns mapped under a multi-column ColumnProperty attribute.

References: #5262

[orm] [usecase] Introduce _orm.relationship.sync_backref flag in a relationship to control if the synchronization events that mutate the in-Python attributes are added. This supersedes the previous change #5149, which warned that viewonly=True relationship target of a back_populates or backref configuration would be disallowed.

5.4.2

pytest 5.4.2 (2020-05-08)

Bug Fixes

#6871: Fix crash with captured output when using the capsysbinary fixture <capsysbinary>.

#6924: Ensure a unittest.IsolatedAsyncioTestCase is actually awaited.

#6925: Fix TerminalRepr instances to be hashable again.

#6947: Fix regression where functions registered with TestCase.addCleanup were not being called on test failures.

#6951: Allow users to still set the deprecated TerminalReporter.writer attribute.

#6992: Revert "tmpdir: clean up indirection via config for factories" #6767 as it breaks pytest-xdist.

#7110: Fixed regression: asyncbase.TestCase tests are executed correctly again.

#7143: Fix File.from_constructor so it forwards extra keyword arguments to the constructor.

#7145: Classes with broken __getattribute__ methods are displayed correctly during failures.

#7180: Fix _is_setup_py for files encoded differently than locale.

5.4.1

pytest 5.4.1 (2020-03-13)

Bug Fixes

#6909: Revert the change introduced by #6330, which required all arguments to @pytest.mark.parametrize to be explicitly defined in the function signature.

The intention of the original change was to remove what was expected to be an unintended/surprising behavior, but it turns out many people relied on it, so the restriction has been reverted.

#6910: Fix crash when plugins return an unknown stats while using the --reportlog option.

pytest 5.4.0 (2020-03-12)

Breaking Changes

#6316: Matching of -k EXPRESSION to test names is now case-insensitive.

#6443: Plugins specified with -p are now loaded after internal plugins, which results in their hooks being called before the internal ones.

This makes the -p behavior consistent with PYTEST_PLUGINS.

#6637: Removed the long-deprecated pytest_itemstart hook.

This hook has been marked as deprecated and not been even called by pytest for over 10 years now.

#6673: Reversed / fix meaning of "+/-" in error diffs. "-" means that sth. expected is missing in the result and "+" means that there are unexpected extras in the result.

#6737: The cached_result attribute of FixtureDef is now set to None when the result is unavailable, instead of being deleted.

[BUG] cbv and path params create strange behaviour

While using the @cbv i encountered the problem that i couldn't use the endpoint without path params on a similar path. It somehow messes with the validator, i think?

from fastapi import APIRouter, FastAPI
from fastapi_utils.cbv import cbv
from pydantic.types import UUID4
from starlette.testclient import TestClient

router = APIRouter()


@cbv(router)
class CBV:

    @router.post("/test")
    def test_post(self):
        return ''


    @router.get("/test/{uuid}")
    def test_post(self, uuid: UUID4):
        return uuid


app = FastAPI()
app.include_router(router)
client = TestClient(app)

print(client.post("/test").json())

output:

{
  "detail":[
    {
      "loc":[
        "query",
        "self"
      ],
      "msg":"field required",
      "type":"value_error.missing"
    }
  ]
}

Expected behavior both endpoints should be just available

Environment:

fastapi_utils_version: 0.2.1
fastapi_version: 0.85.2
pydantic version: 1.10.2
pydantic compiled: True

[QUESTION] What `Wall` means?
Description

When you add a timing middlware I see this on the LOGs:

INFO:app.engine:TIMING: Wall: 320.7ms | CPU: 12.7ms | app.app.users.router.create_user

It is not clear what Wall means... A lot of routes the Wall and CPU values are the same, but sometimes not. I would appreciate any input why this is the case, and what wall means

Trying to create generic CRUD class for all endpoints

I am fairly new to FastAPI(migrating from Django) and I am trying to create a generic CRUD operations class that I can inherit and use across my CBV endpoints. Something like this :

class AbstractCrud
      model: Base = NotImplemented
      session: Session = NotImplemented
  
      def get_items(self, limit,  **filters):
          """ Read operation """
  
      def get_item(self, pk: int):
  
  
      def create_item(self, obj: BaseModel):
          """ Create operation """
  
      def update_item(self, pk: int, **params):
          """ Update operation"""


      def delete_item(self, pk: int):
        """ Delete operation """


router = InferringRouter()

@cbv(router)
class UserAPI(AbstractCrud):
    router.tags = ["User"]
    router.prefix = "/users"
   
    model = User
    session: Session = Depends(get_db)

   # my endpoints
   #e.g. @router.get(...)


@cbv(router)
class PostAPI(AbstractCrud):
    router.tags = ["Post"]
    router.prefix = "/posts"

    model = Post
    session: Session = Depends(get_db)

    # my endpoints
    #e.g. @router.get(...)

I get the following error if I try to do the above: fastapi.exceptions.FastAPIError: Invalid args for response field! Hint: check that <class 'sqlalchemy.orm.decl_api.Base'> is a valid pydantic field type For now, I am able to achieve this as follows:

class AbstractCrud
      model: Base = NotImplemented
      session: Session = NotImplemented
  
      def get_items(self, limit,  **filters):
          """ Read operation """
  
      def get_item(self, pk: int):
  
  
      def create_item(self, obj: BaseModel):
          """ Create operation """
  
      def update_item(self, pk: int, **params):
          """ Update operation"""


      def delete_item(self, pk: int):
        """ Delete operation """
        

class UserCrud(AbstractCrud):

    def __init__(self, session: Session):
        self.session = session
        self.model = User


class PostCrud(AbstractCrud):

    def __init__(self, session: Session):
        self.session = session
        self.model = Post


router = InferringRouter()

@cbv(router)
class UserAPI:
    router.tags = ["User"]
    router.prefix = "/users"
   
    def __init__(self, session=Depends(get_db)):
        self.session = session
        self.crud = UserCrud(self.session)

   # my endpoints
   #e.g. @router.get(...)


@cbv(router)
class PostAPI:
    router.tags = ["Post"]
    router.prefix = "/posts"

    def __init__(self, session=Depends(get_db)):
        self.session = session
        self.crud = PostCrud(self.session)

    # my endpoints
    #e.g. @router.get(...)

Although this is working fine for me now, I can't help but think if there is a better(or correct) way to do this.

Also, Is my use of a single router variable across multiple classes correct?

[QUESTION] There's a way to add a custom decorator to a class-based view?

I'm trying to do something like the following:

@cbv(users_router)
@ResponseHandler.class_decorator
class Users:

    controller = UserController()

    @users_router.post("/users", status_code=201)
    async def create_user(self, user_data: Dict, response: Response) -> Dict:
        return self.controller.create_user(**user_data)

    @users_router.get("/users/{user_id}", status_code=302)
    async def get_user(self, user_id: int, response: Response) -> Dict:
        return self.controller.obtain_user(user_id)

    @users_router.get("/users", status_code=302)
    async def get_all_users(self, response: Response) -> Dict:
        return self.controller.obtain_all_users()

The class_decorator decorator adds custom response for each one of the requests, but when I try to execute one of the services, then this error appears:

{"detail":[{"loc":["query","self"],"msg":"field required","type":"value_error.missing"}]}

Don't infer `response_model` for invalid types

It is possible for inferring_router to raise an exception if a function uses a return type that is not a valid response_model. An example is an endpoint that returns Response instead of letting FastAPI construct one.

This PR fixes that by only inferring the response_model if the return annotation is a valid response_model.

Fixes #229 Fixes #172
