I am trying our the teams & team members function.  When I delete a team member from a team, I got error message like this 

#######

Couldn't find Team with 'id'=8 [WHERE "team_members"."user_id" = $1]

    def set_team
      @team = current_user.teams.find(params[:team_id])
    end

    # Use callbacks to share common setup or constraints between actions.

Any One help ? 

Actually, it would be nice if some one demo the functionalities and use cases of team and team membership, since the that would be the foundation of SaaS application.
