I am using a PostgreSQL 14.2-1 Windows x64 database using pgAdmin to which I am connecting to like so:
engine = create_async_engine(DATABASE_URL,
future=True, echo=True,
pool_use_lifo=True, pool_pre_ping=True, pool_recycle=7200
)
async_session_maker = sessionmaker(engine, class_=AsyncSession,
expire_on_commit=False)
Base: DeclarativeMeta = declarative_base()
Using the following SQL script I have made the table dbo.Quote
, like so:
CREATE TABLE dbo.Quote
(
"ID" bigint GENERATED ALWAYS AS IDENTITY,
"UUID" uuid NOT NULL DEFAULT gen_random_uuid(),
"DateCreated" timestamp with time zone NOT NULL DEFAULT CURRENT_TIMESTAMP,
"DateModified" timestamp with time zone NOT NULL DEFAULT CURRENT_TIMESTAMP,
"IsActive" boolean NOT NULL DEFAULT TRUE,
"Text" character varying(512) NOT NULL,
"Author" character varying(126) DEFAULT 'Unknown',
"Origin" character varying(126) DEFAULT 'Unknown',
"UserID" bigint,
CONSTRAINT "FK_Quote_Users" FOREIGN KEY ("UserID")
REFERENCES auth.users ("ID") MATCH SIMPLE
ON UPDATE NO ACTION
ON DELETE NO ACTION
NOT VALID,
PRIMARY KEY ("ID")
);
ALTER TABLE IF EXISTS dbo.Quote
OWNER to postgres;
I have also developed an SQLAlchemy model for the dbo.Quote
postgres table:
class Quote(Base):
__tablename__ = 'quote'
__table_args__ = {'schema': 'dbo'}
ID = Column(BigInteger, Identity(always=True, start=1, increment=1,
minvalue=1, maxvalue=9223372036854775807, cycle=False, cache=1), primary_key=True)
UUID = Column(UUID, nullable=False, server_default=text("gen_random_uuid()"))
DateCreated = Column(DateTime(True), nullable=False, server_default=text("CURRENT_TIMESTAMP"))
DateModified = Column(DateTime(True), nullable=False, server_default=text("CURRENT_TIMESTAMP"))
IsActive = Column(Boolean, nullable=False, server_default=text("true"))
Text = Column(String(512), nullable=False)
Author = Column(String(126), server_default=text("'Unknown'::character varying"))
Origin = Column(String(126), server_default=text("'Unknown'::character varying"))
UserID = Column(BigInteger, ForeignKey('auth.users.ID'))
`
I am using an AsyncSession generator, such as you have exemplified in your simple example, namely:
`
async def get_transaction_session() -> AsyncSession:
async with async_session_maker() as session:
async with session.begin():
yield session
and I am adding the crud router builder like so
QuoteCRUDRouter = crud_router_builder(db_model=Quote,
prefix='/quote', tags=['Quote'],
exclude_columns=['UUID','DateCreated','DateModified','IsActive'],
crud_methods=[CrudMethods.CREATE_ONE],
async_mode=True,
autocommit=False,
db_session=get_transaction_session,
)
Finally, when I run
import uvicorn
if __name__ == "__main__":
uvicorn.run("app.app:app",
# host="0.0.0.0", # defaults to localhost
log_level="info", reload=True)
I get the following error

Why am I getting this error?
Also, because SQLite does not have schemas, the __table_args__
in the SQLAlchemy model cause a problem, so what is the issue with that as well?
Python 11 + SQLAlchemy 2.0 will ever be bumped?
Dear Sir,
I have installed the FastAPIQuickCRUD and also generator.
BUT How to run and which path IS NOT clear in the README File.
Please guide
Also Where should the user setup the variable SQLALCHEMY
Please reply
Regards,
After the foreign tree feature, I will focus on the Codegen feature, since #6 . Which make it easier for us to develop the API we want than now, you can modify the code to develop your own api based on this project
The CodeGen feature will not generate with join_foreign_table
field
13 mar 2022
The development is quite smooth and no blocking, I thing it can be released after 3 week
Hi,
I would like to test your module which suits with my needs, but I'm facing out issue with tutorial/sample.py.
When I launch this, I get this error:
.\global_venv\lib\site-packages\fastapi_quickcrud\misc\schema_builder.py:263: UserWarning: The column of id has not default value and it is not nullable and in exclude_listit may throw error when you insert data
warnings.warn(
Traceback (most recent call last):
File "./api/run3.py", line 23, in <module>
crud_route_parent = generic_sql_crud_router_builder(
File ".\global_venv\lib\site-packages\fastapi_quickcrud\crud_router.py", line 400, in crud_router_builder
api = APIRouter(**router_kwargs)
TypeError: __init__() got an unexpected keyword argument 'sql_type'
It seems, the parameter sql_type is not expected by the FastApi class APIRouter. I checked quickly this class on FastAPI github, but I found no change for a while, missed I something ?
Best regards,
This is such a cool package, but I ended up not using it because I wanted my API to look like this. I thought I would just leave it as a suggestion.
Suppose I have this in sqlalchemy:
import sqlalchemy as sa
class Account(Base):
__tablename__ = "account"
id = sa.Column(sa.Integer, primary_key=True, autoincrement=True)
class BlogPost(Base):
__tablename__ = "blog_post"
id = sa.Column(sa.Integer, primary_key=True, autoincrement=True)
account_id = sa.Column(sa.Integer, sa.ForeignKey("account.id"), nullable=False)
class BlogComment(Base)
__tablename__ = "blog_comment"
id = sa.Column(sa.Integer, primary_key=True, autoincrement=True)
blog_id = sa.Column(sa.Integer, sa.ForeignKey("blog_post.id"), nullable=False)
I might want routes like this:
GET /account/<account_id>/post/
{ list of blog posts by the author }
POST /account/<account_id>/post/
# creates a new blog post for the author
GET /post/<post_id>/comment
{ list of comments on the blog post }
GET /account<account_id>/post/<post_id>/comment
{ list of comments on the blog post - not sure how this is compared to the one above }
Anyways, just a thought!
I created a few SQLAlchemy models containing some PostgreSQL data types such as
from sqlalchemy.dialects.postgresql import BYTEA, INTERVAL, JSONB, UUID
and I encountered the following exception
fastapi_quickcrud.misc.exceptions.ColumnTypeNotSupportedException: The type of column Blob (BYTEA) not supported yet
I haven't tested the other types except for Postgres BYTEA, however, there might be an issue for from sqlalchemy import ARRAY
as well.
I want to build a ReactJS app in which I can upload a photo via a FastAPI endpoint and store it in the BYTEA field. Afterwards, I would also like to have a FastAPI endpoint that lists all of the BYTEA entries, which I can use to make a gallery in ReactJS.
class Photo(Base):
__tablename__ = 'photo'
__table_args__ = {'schema': 'dbo'}
ID = Column(BigInteger,
Identity(always=True, start=1, increment=1, minvalue=1, maxvalue=9223372036854775807, cycle=False,
cache=1), primary_key=True)
UUID_ = Column('UUID', UUID, nullable=False, server_default=text('gen_random_uuid()'))
DateCreated = Column(DateTime(True), nullable=False, server_default=text('CURRENT_TIMESTAMP'))
DateModified = Column(DateTime(True), nullable=False, server_default=text('CURRENT_TIMESTAMP'))
IsActive = Column(Boolean, nullable=False, server_default=text('true'))
Blob = Column(BYTEA, nullable=False)
...
PhotoCRUDRouter = crud_router_builder(db_model=Photo,
db_session=get_transaction_session,
prefix='/quote', tags=['Photo'],
exclude_columns=['UUID','DateCreated','DateModified','IsActive'],
async_mode=True,
autocommit=False,
sql_type=SqlType.postgresql,
)
app.include_router(PhotoCRUDRouter)
Root cause:
Compatibility issue between latest version of pydantic and dataclasses
poetry add fastapi-quickcrud
Using version ^0.2.4 for fastapi-quickcrud
Updating dependencies
Resolving dependencies... (1.6s)
Because no versions of fastapi-quickcrud match >0.2.4,<0.3.0
and fastapi-quickcrud (0.2.4) depends on uvicorn (0.17.0), fastapi-quickcrud (>=0.2.4,<0.3.0) requires uvicorn (0.17.0).
And because uvicorn (0.22.0) depends on uvicorn (0.22.0)
and no versions of uvicorn match >0.22.0,<0.23.0, fastapi-quickcrud (>=0.2.4,<0.3.0) is incompatible with uvicorn (>=0.22.0,<0.23.0).
So, because backend depends on both uvicorn (^0.22.0) and fastapi-quickcrud (^0.2.4), version solving failed.
Is it possible to write out all the routers into a python file?
Which would be great while we add more end points for the tags
