Delete

strawchemy.delete() builds a mutation field that removes records. The field returns the deleted records, so the field selection of a query works here too.

Deleting by filter

Pass a filter input to strawchemy.delete() to remove only the records it matches:

@strawchemy.filter(Post, include="all")
class PostFilter: ...


@strawberry.type
class Mutation:
    delete_posts_filter: list[PostType] = strawchemy.delete(PostFilter)

mutation {
    deletePostsFilter(filter: { views: { lt: 10 } }) {
        id
        title
    }
}

The filter takes the same input as a query filter, related records included.

Deleting everything

Leave out the filter argument and the mutation removes every record of the type instead:

@strawberry.type
class Mutation:
    delete_posts_filter: list[PostType] = strawchemy.delete(PostFilter)
    delete_posts: list[PostType] = strawchemy.delete()  

mutation {
    deletePosts {
        id
        title
    }
}
