Example Code

statement = select(Event).where(Event.user_public_id == user.public_id)
if suggested_by:
     statement.filter(Event.suggested_by.contains(suggested_by))

Description

using SQLAlchemy I would do this

if suggested_by:
     query.filter(Event.suggested_by.contains(suggested_by))

assuming I have a statement like this:

statement = select(Event).where(Event.user_public_id == user.public_id)
if suggested_by:
     statement.filter(Event.suggested_by.contains(suggested_by))

As seen above I still use the SQLAlchemy logic in the above because I couldn't figure out any way to do this with SQLModel. Is there any way to perform a where/like query with this library?

I am looking for a way to achieve this, too. In sqlalchemy, it is possible to do this with something like User.name.ilike(search), but I am using vscode with this option "python.analysis.typeCheckingMode": "basic" and it has squiggly lines on it. The work-around I have seems a bit messy. Hope something gets implemented to solve this soon. Other than that I really like sqlmodel

Kindly try this, it work for me.

select(User).where(User.name.like(’%’+ keyword + ‘%’))

Yup, as i stated in the OP, i can reach for the underlying sqlalchemy api and do this. But this doesn't give me the same kind of type safety and editor completion as I would get otherwise.

Given this is a few months later, there may have been improvements in SQLModel. The following seems to work by importing col and explicitly wrapping the column before using contains.

select(Event).where(col(Event.suggested_by).contains(suggested_by)

Thanks, @johnziebro your solution made it really simple also with custom queries.

query = select(User).where(and_(User.role_id == role.id, or_(col(User.first_name).contains(name), col(User.last_name).contains(name)))).order_by(User.first_name)

@johnziebro while your solution works beautifully, would it be possible to also make it case-insensitive?

[dmtea]

It did not worked for me (I mean vscode has squiggly lines on it too). But this worked for me:

...
from sqlmodel import column
...
_contents = session.query(Content).filter(column("link").contains("something")).order_by(ordering).offset(offset).limit(limit).all()

But it would be better with "Class.column" implementation :/

@mrsakkaro A bit late, but using regexp_match(value, "i") instead of contains(value) does the trick.
