Using update_attributes with column type of array

Question

I have a languages column which is an array of strings with

add_column :table, :languages, :string, array: true, default: []

When I use update_attributes on that model, all columns are being updated except the languages column which remains []

Is there anything special needed to do here?

When you post an array onto an action in the controller, you should permit like this:

params.require(:table).permit( {:languages => []}, :other_field, :other_field2... )

languages is permitted in the table_params

Is it permitted as an array?

this kind of permission will only allow empty arrays

I copied/pasted this from an app of mine and it is working perfectly... It tells the controller to permit languages as an array, not an empty array

Glad to having helped.
