How do I navigate to a parent route from a child route

Question

My problem is quite classic  I have a private part of an application which is behind a login form  When the login is successful  it goes to a child route for the admin application   My problem is that I can t use the global navigation menu because the router tries to route in my AdminComponent instead of my AppCompoment  So my navigation is broken   Another problem is that if someone want to access the URL directly  I want to redirect to the parent  login  route  But I can t make it work  It seems to me like theses two issues are similar   Any idea how it can be done

To navigate to the parent component regardless of the number of parameters in the current route or the parent route  Angular 6 update 1 21 19     let routerLink   this  aRoute parent snapshot pathFromRoot          map  s    gt  s url           reduce  a  e    gt                  Do NOT add last path              if  a length   e length     this  aRoute parent snapshot pathFromRoot length                    return a concat e                             return a                      map  s    gt  s path       this  router navigate routerLink     This has the added bonus of being an absolute route you can use with the singleton Router    Angular 4  for sure  probably Angular 2 too

My routes have a pattern like this    user edit 1 -  Edit user create 0 -  Create user  -  List   When i am on Edit page  for example  and i need go back to list page  i will return 2 levels up on the route   Thinking about that  i created my method with a  level  parameter   goBack level  number   1        let commands              this router navigate  commands repeat level      relativeTo  this route         So  to go from edit to list i call the method like that   this goBack 2
