Answer 1

Data hash should be like this:

{user: {active: false}, data_attributes: {active: false}, nickname: "nick"}

Problem is that your hash is:

Parameters: {"data"=>{"active"=>false}, "data_attributes"=>{"active"=>false}, "nickname"=>"nick", "id"=>"1", "user"=>{"nickname"=>"nick"}}

It should be:

Parameters: {"user"=>{"nickname"=>"nick", "id"=>"1","data_attributes"=>{"active"=>false}}
