Support FilterableField on array fields

[rostaingc]

Is your feature request related to a problem? Please describe.

I have a column defined as

@Column({ type: 'text', array: true, default: [] })
userIDs: string[]

I would like to filter my entity based on values inside this array.

But FilterableField does not support text array columns.

Have you read the Contributing Guidelines?

yes

Describe the solution you'd like
Be able to add the FilterableField(() => [String]) decorator on that field.

Describe alternatives you've considered
Currently I have changed my column to a simple text and the userIDs set to a string type.
I ve added FilterableField(() => String) and making queries with like '%x%'
