The ActivatedRoute in Angular2 is displaying an error message stating "Cannot resolve all parameters for Detail_retail

Currently, I am working with Angular JS version 2.0.0 where I am passing values through my code:

import {Component} from "angular2/core"
import {bootstrap} from 'angular2/platform/browser';
import {Users} from "../users/component"
import {Users_detail} from "../users_detail/component"

import {
    RouteConfig,RouterModule,
    ROUTER_DIRECTIVES,
} from 'angular2/router';

@RouteConfig([
    {path:'/users', name: 'Users', component: Users},
    {path:'/users_detail/:id', name: 'Users_detail', component: User_retailer},
])

I am encountering an issue on how to retrieve the 'id' value in the 'Users_detail' file, users_detail.ts.

import { Router,ActivatedRoute } from 'angular2/router';

constructor( private route: ActivatedRoute) {

}

An error message is being shown as follows:

"Cannot resolve all parameters for User_retailer(?). Make sure they all have a valid type or annotations."

Answer №1

The component you are referring to is called Users_detail after importing it:

import {Users_detail} from "../users_detail/component"

However, in your RouteConfig, you have specified component: User_retailer.

To correct this, update your RouteConfig as follows:

@RouteConfig([
    {path:'/users', name: 'Users', component: Users},
    {path:'/users_detail/:id', name: 'Users_detail', component: Users_detail},
    ])

You can retrieve the id parameter like this:

let id = this.route.snapshot.params['id']

I hope this information proves helpful.
