Redirecting on rejected resolve

[cadilhac]

Hi,

Using ui-router 1.0rc1, I can't find a way, in my state declaration (component-routed), to redirect to another state when a resolve is rejected (my server sends back a 400 status code when a resource can't be found). Is a hook necessary? I hope there is a solution that can be local to each state declaration instead of in a global hook...
I don't think calling $state.go() in a rejection handler inside my resolve function is the thing to do. It seems to work but I noticed that other resolves are called (and one of them depends on the rejected one).

Thanks

You could set this up in your app's run block:

$state.defaultErrorHandler(function(error) {
    // ... 
   $state.go('someErrorState', { errorMessage: error }); // careful not to create an infinite loop here
});

The reject result of the resolve should be passed to the error handler.

I want to avoid having a global place with if statements. I would like to stay in my state definition.

You raise a really good point.

Resolves are not considered to be "transition hooks" so they cannot explicitly redirect the transition. The reason your other resolves are still processing is likely because you need to return the rejection from the failed resolve. Something like this:

.state('foo', {
  resolve: {
    fails: ($q, $http, $state) => 
      $http.get('/404').catch(err => $state.go('recover') && $q.reject(err))
  }
});

That should cause the resolve to be rejected (erroring the first transition). Then the second transition (state.go) can proceed

Thanks, I can try that. But do you feel it as a woraround or something that integrates well with the framework?

[christopherthielen]

I feel it's a workaround.

I think you've raised a good point about a possible enhancement to the framework.

[cadilhac]

The workaround worked well. But note that I had to "return" $q.reject(err) to ensure that the rejection is taken into account so that the other resolves are not attempted.

Revisiting my code and I had a link to this thread in my comments.
Is there anything new related to this issue?
Thanks.
