Set attribute in has_many relation table

I have a Group and a User which are related through a has_many :through relation. My :through table is called Groupuser. This table has a group_id, user_id and a status. On creation of my Group i'd let to set the status of the current_user being added to 1(where default is 0).

Setting the current_user in my group is no problem at all and works perfectly fine; Its status I can't figure out though. This is what I have now:

  def create
    @group = Group.new(group_params)
    respond_to do |format|
      if @group.save
        @group.users << current_user
        @group.groupusers.status << 1
        format.html { redirect_to @group, notice: 'done' }
        format.json { render action: 'show', status: :created, location: @group }
      else
        format.html { render action: 'new' }
        format.json { render json: @group.errors, status: :unprocessable_entity }
      end
    end
  end

Above code throws the error: undefined methodstatus' for #`

My schema for Groupuser looks like this: (I've tried without ID aswell, to no avail)

  create_table "groupusers", force: true do |t|
    t.integer "group_id"
    t.integer "user_id"
    t.integer "status",   default: 0
  end

The @group.groupusers is an array, activerecord relation. You can't set an attribute like that, you need to set it one by one or before you append it to the group. 

@group.groupusers.each do |gu|
  gu.status = 1
  gu.save
end

or

groupuser = GroupUser.new user_id: current_user.id, status: 1
@group.groupusers << groupuser

Try @group.groupusers.status = 1

@group.save!
