PERTAIN_TOProblem

Zustand persist middleware does not write during the test setup

PERTAIN_TOProblem

Tension: I am not satisfied with is to prefix the Home.tsx file so it looks like this: `-Home.tsx` (adding a minus) This way this file is ignored. Outcome: Is there a better way to configure this using the tsr.config.json?

PERTAIN_TOSolution

explicitly configuring Prisma to generate the client binaries to a custom output directory `node_modules/prisma-client` — // prisma/schema.prisma generator client { provider = "prisma-client-js". Tension: Then doing a search-and-replace of the import statements, replacing `from '@prisma/client'` with `from 'prisma-client'`. Outcome: output = "../node_modules/prisma-client".

PERTAIN_TOProblem

Prisma Client could not locate the Query Engine for runtime "rhel-openssl-3.0.x". — when I deploy. Tension: This is likely caused by a bundler that has not copied "libquery_engine-rhel-openssl-3.0.x.so.node" next to the resulting bundle. Outcome: Ensure that "libquery_engine-rhel-openssl-3.0.x.so.node" has been copied next to the bundle or in "generated/prisma".

PERTAIN_TOSolution

override Build command to `npx prisma generate && next build` — under Build & Development Settings. Tension: API route failed. Outcome: Redeploy the app.

PERTAIN_TOSolution

Set Up Environment Variables: — You need to set the POSTGRES_URL environment variable with your database connection string. Outcome: Ensure that you have the correct environment variables set up in your project.

PERTAIN_TOProblem

Drizzle schema location appears duplicated between drizzle(sql, { schema }) and drizzle.config.ts

PERTAIN_TOSolution

Use drizzle.config.ts for Drizzle Kit configuration and pass schema to drizzle() only when using the relational query builder

PERTAIN_TOProblem

PrismaClientInitializationError on Vercel when connecting to Supabase

PERTAIN_TOSolution

Add directUrl to the Prisma schema, set a pooled Supabase connection string with ?pgbouncer=true for DATABASE_URL, and use the primary postgres URL for DIRECT_URL

PERTAIN_TORootCause

re-runs every migration via a raw `for f in migrations/*.sql; psql -f` loop. Tension: it relies on tolerated `relation X already exists` errors. Outcome: non-idempotent legac.

PERTAIN_TOProblem

sqlite3.OperationalError: database is locked. — I trigger `/session_a` and `/session_b` almost simultaneously. Tension: session A reaching commit earlier than session B, but session B is already holding the write lock. Outcome: A will inevitably fail with a database is locked error.

PERTAIN_TOSolution

If you convert all operations to perform asynchronously (using `aiosqlite`) , the issue will be mitigated. — When a route in FastAPI is listed as asynchronous (`async def`). Tension: that doesn't fully solve the inherent single writer problem of Sqlite. Outcome: Here's a fully operational update of the FastAPI server logic:.

PERTAIN_TOProblem

ValueError: has no matching SQLAlchemy type — class Category(SQLModel, table=True). Tension: referring to the `category.py` field `todos: list["Todo"]`, while the relation `hero/team` does work. Outcome: I encountered this issue when I tried to define field with `list[str]` type.

PERTAIN_TOSolution

solved it by making the field store data in JSON — using `Column` and `JSON` from `sqlalchemy`. Tension: labels: list[str] | None = None. Outcome: labels: list[str] | None = Field(default=None, sa_column=Column(JSON)).

PERTAIN_TOPackage

alembic

PERTAIN_TORootCause

Conditional by default, will not attempt to recreate tables already present in the target database. Tension: SQLModel uses the SQLAlchemy library and builds on it. Outcome: This means that once created, SQLModel will not attempt to change the schema of your database tables.

PERTAIN_TOProblem

if i change some property on Vehicle model and run this code again, I don't see any change on table — Vehicle.metadata.create_all(engine). Tension: I want that change to be detected and automatically migrated to database. Outcome: once created, SQLModel will not attempt to change the schema of your database tables.

PERTAIN_TOSolution

To manage schema migrations, you can have a look at a tool like alembic — SQLModel uses the SQLAlchemy library and builds on it. Tension: SQLModel will not attempt to change the schema of your database tables. Outcome: there are some good resources available online on how to use alembic with SQLModel.

PERTAIN_TOProblem

that will give me 3 levels deep of nodes in my json output — I have a many to many self referential relationship. Tension: is there a way to do that so it goes as many levels deep as needed until nodes = [] ? Outcome: Do I need to use something like marshmallow-sqlalchemy ?

PERTAIN_TOSolution

select_options=[ selectinload(Parent.child) .selectinload(Node.nodes) ] — possible workaround if there's a way to do this dynamically. Outcome: for option in select_options: query = query.options(option).

PERTAIN_TOSolution

Tension: this eliminates the need for a loop. Outcome: this eliminates the need for a loop.

PERTAIN_TOProblem

the first relationship is always automatically loaded although it shouldn't — using SQLAlchemy and Pydantic with a Postgres-Database. Tension: The second relationship works as expected. Outcome: I am going to have two different endpoints.

PERTAIN_TOSolution

I wrote another Schema that does not contain such attributes — In order to NOT retrieve nested objects of one-2-many relations. Tension: one that contains only basic attributes for a flat response. Outcome: one that contains the relationships.

PERTAIN_TOProblem

print(session.sync_session.scalars(stmt)) # fails with — @app.post('/users') async def get_users(session: AsyncSession = Depends(get_session)). Tension: I'd like to use `AsyncSession.sync_session` but the code below fails with error. Outcome: the code is a simplified version of real case.

PERTAIN_TOSolution

I'd like to use `AsyncSession.sync_session` — async def get_session() -> AsyncSession: session = SessionLocal(). Tension: the code below fails with error. Outcome: use `AsyncSession.sync_session` but the code below fails with error.

PERTAIN_TOProblem

cannot adapt type 'dict' using placeholder '%s' (format: AUTO) — running query below query i'm getting error. Tension: I want check whether the particular email template is used in any other model instance and model Rule we have action(JSONB). Outcome: Rather than trying to construct a JSON literal in SQLAlchemy you could let Postgres do it using the `jsonb_build_object` function.

PERTAIN_TOProblem

PermissionSchema.model_validate(permission) cannot build a schema from an SQLModel instance

PERTAIN_TOSolution

I'm getting `AttributeError: model_dump`. — I want to convert the list of `model.Permission` fetched from the database to `schema.Permission`. Tension: Since both are Pydantic models, it should be sufficient to `model_dump` -> `model_validate`, but I'm getting `AttributeError: model_dump`. Outcome: You should use `from_attributes=True` in model config to be able to build your schema from a db model.

PERTAIN_TOSolution

Use the db client itself and call self.db_client.session() inside the service

PERTAIN_TOSolution

Session() — sessionmaker(bind=self.engine).

PERTAIN_TOProblem

GET /elements/?skip=0&limit=10&services=Test. Tension: the filter does not work as expected. Outcome: FROM elements WHERE (elements.services LIKE '%%' || %(services_1)s || '%%')) AS anon_1].

PERTAIN_TOSolution

Define services as JSONB — using SQLAlchemy and PostgreSQL. Tension: I need to filter results based on a value in a JSON array column. Outcome: query = query.filter(professional_model.Professional.services.op('@>')(cast(func.to_jsonb([filters['services']]), JSONB))).

PERTAIN_TOProblem

does not populate by query — retrieve via query results from two related tables via a third mid table. Tension: It's a relationship between Product - Category via ProductCategory join.

PERTAIN_TOSolution

call one off the other and not list them separately with a comma.

PERTAIN_TOProblem

SQLModel/Pydantic serializes the `categories: list[Category]` field as nested objects, but the API response needs `categories` as `list[str]` containing `Category.name` values.

PERTAIN_TOSolution

Separate the database model from the response DTO and map `categories` explicitly (e.g., create a `PostDTO` with `categories: list[str]` and convert with a `from_db_model` that uses `[c.name for c in model.categories]`).
