some basic questions about collections and removing attributes. i’m using typesense rails gem and ruby client. if i were to remove an existing attribute from my model, do i have to recreate the collection to update the schema, and reindex the collection again? What would be the recommended way to handle attribute removal?

Dropping fields doesn't require reindexing, you just call out to the update function, mention the field you want dropped like:

fields: [
  {
    name: "price",
    drop: true,
  },
]

And if the update operation is successful, then the fields will be dropped automatically
