Hi all,

I am using RUBY language to implement google drive, I have three folder in google drive(d1, d2, d3), and d1 is parent to d2, now I wants update a parents of d2 like remove d1 parent from d2 and add d3 as parent or keep both as a parents.

I tried like below. but i getting undefined method update_file.

Here is the link I followed: https://developers.google.com/drive/v3/web/folder.

file = drive_service.update_file(file_id,
                                 add_parents: folder_id,
                                 remove_parents: previous_parents,
                                 fields: 'id, parents')
