I am facing difficulties in making the path show up on the screen

const routes: Routes = [
    { path: '', redirectTo: '/students', pathMatch: 'full' },
    {
       path: 'students',
       component: StudentsComponent,
       children: [
           { path: '', component: StudentSignupComponent },
           { path: 'all-students', component: AllStudentsComponent },
           { path: ':id', component: StudentComponent}
       ]
    },

      <ul *ngFor="let student of students; let i = index" class="list-group">
    <a [routerLink]="[i]">e

I encountered an error when using this code:

Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: 'students/all-students/0'

What steps should I take to resolve this issue?

Answer №1

To improve the organization of your routes, you can make changes similar to the previous comment:

const routes: Routes = [
  { path: '', redirectTo: '/students', pathMatch: 'full' },
  {
    path: 'students',
    component: StudentsComponent,
    children: [
      {
        path: 'all-students', component: AllStudentsComponent,
        children: [ { path: ':id', component: StudentComponent} ]
      }
      { path: '', component: StudentSignupComponent, patchMatch:'full' },
    ]
  }
];

Next step is to display the list of students using *ngFor in your all-students component:

<ul class="list-group">
  <li *ngFor="let student of students; let i = index">
    <a routerLink="/{{ student.id }}">{{ student.name }}</a>
  </li>
</ul>

This assumes that your students list is an array of objects like this:

students = [
  { name: "Girgis", age: 26, id: "e772df14-e19e-45cf-8961-c2f0b701a61b" },
  { name: "Bernhardt du Toit", age: 26, id: "0401306b-5919-4c2d-b25f-6e8ff389b8aa" }
];

Answer №2

For the student with an ID of 0, it is recommended to utilize the path 'students/0'

Answer №3

When setting up your routes, make sure to use the :id as a child of all-students like this:

const routes: Routes = [
{ path: '', redirectTo: '/students', pathMatch: 'full' },
{
path: 'students',
component: StudentsComponent,
children: [
  {
    path: 'all-students', component: AllStudentsComponent,
    children: [
    { path: ':id', component: StudentComponent}
  ]},
  { path: '', component: StudentSignupComponent, patchMatch:'full' },
]
},

It's recommended to include an empty route with patchMatch:full for rendering only when there is a complete match.

Answer №4

Perhaps consider giving this a shot? It's worth experimenting with 

const routes: Routes = [
    { path: '', redirectTo: '/students', pathMatch: 'full' },
    {
       path: 'students',
       component: StudentsComponent,
       children: [
           { path: '0', component: StudentSignupComponent },
           { path: 'all-students', component: AllStudentsComponent },
           { path: ':id = 0', component: StudentComponent}
       ]
    },

      <ul *ngFor="let student of students; let i = index" class="list-group">
    <a [routerLink]="[i]">
