Hope this helps To restrict access to workorders that match the current user's group, I would make the following modifications:
code :
# Ensure the group of the work order always matches the current_user's group
def workorder_params
  params.require(:workorder).permit(
    :contractor_id, :description, :estimatedtime, 
    :startdate,:completiondate, :budgetoverhead
  ).merge(group: current_user.group)
end
def set_workorder
  @workorder = Workorder.where(id: params[:id], group: current_user.group).first
end
can :update, Workorder, group: user.group

Hope this helps I need to insert the group_id of a user(user in auth_user table) to auth_user_groups table. How can we achieve this?
code :
user = User.objects.get(id=1)
group = Group.objects.get(id=5)

user.groups.add(group)
Can you explain SQLwise why this INSERT statement only gets run if the SELECT statement fails? (rails first_or_create)

this one helps. That's the point of the method. first_or_create will get the first record, or create one if there are no records that match the query. You can see that from the source code:
code :
# File activerecord/lib/active_record/relation.rb, line 117
def first_or_create(attributes = nil, options = {}, &block)
  first || create(attributes, options, &block)
end
BEGIN
INSERT INTO clients (created_at, first_name, locked, orders_count, updated_at) VALUES ('2011-08-30 05:22:57', 'Andy', 0, NULL, '2011-08-30 05:22:57')
COMMIT

This might help you Since there are many UserGroup records for each user and an ArchivedUserGroup has the same attributes as a regular UserGroup (user_id, group_id), I think you should be created an ArchivedUserGroup for each of the users UserGroup records and not just one. You're trying to pass a set (like an array) to the group_id column. Although you haven't shown your schema, probably group_id is an integer since it's a foreign key, so there's a data type mismatch. Instead you could do this:
code :
UserGroup.where(user_id: self.id).each do |user_group|
  ArchivedUserGroup.create(
    user_id: self.id,
    group_id: user_group.group_id
  )
end

will help you I'm trying to create a column with group_id during the SELECT statement. , You can do this with a cumulative sum. For just an assignment:
code :
select t.*,
       coalesce(sum(case when event = 'purchase' then 1 else 0 end) over
                    (order by contact_id, product_code, timestamp desc
                     rows between unbounded preceding and 1 preceding
                    ), 1) as grp
from t;
select t.*,
       sum(case when prev_event = 'purchase' or seqnum = 1 then 1 else 0 end) over
                (order by contact_id, product_code, timestamp) as grp
from (select t.*,
             row_number() over (partition by contact_id, product_code order by timestamp) as seqnum,
             lag(event) over (order by contact_id, product_code, timestamp) as prev_event
      from t
     ) t
order by 1, 2, 3;
select t.*, dense_rank() over (order by _grp) as grp
from (select t.*,
             sum(case when prev_event = 'purchase' or seqnum = 1 then 1 else 0 end) over
                      (order by contact_id, product_code, timestamp) as _grp
      from (select t.*,
                   row_number() over (partition by contact_id, product_code order by timestamp) as seqnum,
                   lag(event) over (order by contact_id, product_code, timestamp) as prev_event
            from t
           ) t
     ) t
order by 1, 2, 3;

like below fixes the issue The type of group_id is GroupMaster and the data type of user.group_id column is INT.
The error says that MyBatis does not know how to convert GroupMaster into INT.
code :
@Insert("INSERT INTO users(group_id, login_name, password, full_name,"
        + "full_name_kana, birthday, email, tel, rule, salt) VALUES"
        + "(#{group_id.group_id}, #{login_name},#{password}, #{full_name}, #{full_name_kana},"
        + "#{birthday}, #{email}, #{tel}, #{rule}, #{salt})")
