ruby on rails - how to add the current user_id automatically to another table? -

i've been playing models bit.

i using devise

my schema:

  create_table "complaints", force: :cascade |t|     t.string   "title"     t.text     "complaint_info"     t.datetime "created_at",     null: false     t.datetime "updated_at",     null: false     t.integer  "user_id"   end    add_index "complaints", ["user_id"], name: "index_complaints_on_user_id", using: :btree    create_table "users", force: :cascade |t|     ...   end 

complaint model:

class complaint < activerecord::base   belongs_to :user    validates :title, presence: true end 

users model:

class user < activerecord::base   # include default devise modules. others available are:   # :confirmable, :lockable, :timeoutable , :omniauthable   devise :database_authenticatable, :registerable,          :recoverable, :rememberable, :trackable, :validatable    has_many :complaints end 

i assuming setup rails assume current_user id goes inside user_id it's not storing it, have manually in controller this:

def create     @complaint = complaint.new(complaint_params) |c|       c.user_id = current_user.id     end      if @complaint.save       redirect_to dashboard_complaint_path(@complaint)     else       render 'new'     end   end  private    def complaint_params     params.require(:complaint).permit(:title, :complaint_info)   end 

is right way it? thanks.

for rails automatically set foreign key need create new record through parent records association.

@complaint = current_user.complaints.new(complaint_params)
