Params field is empty in $router.push - vue.js

Question

Consider this:
this.$root.$router.push({
path: '/dashboard',
params: { errors: 'error' },
query: { test: 'test' }
})
I use this in my component to redirect to another URL, and some error has occured. The problem is that when I want to access params field in dashboard component, it's empty. The query field works well. I'm trying to access it by this.$route.params.errors.

Answer 1

You can use params only with named paths (i think).
Example:
//route (in your router file should have "name")
{ path: '/errors', name: 'EXAMPLE', component: ... }
//navigating
this.$router.push({
name: 'EXAMPLE',
params: { errors: '123' }
});
Now it will have correct value in this.$route.params.

Answer 2

If you don't want to use named routes you can try this:
ES6
this.$root.$router.push({
path: `/dashboard/${error}`,
query: { test }
})
ES5
this.$root.$router.push({
path: '/dashboard/' + error,
query: { test: 'test' }
})

I faced the similar issue where in one of my views (component). I was trying to navigate (programmatically) from /foo/bar to /foo/bar/123, but the route param was not available later in the component. My relevant navigation code looked like below:
methods: {
save_obj() {
let vm = this;
// Make AJAX call to save vm.my_obj, and on success do:
let v = `${vm.$route.path}/${vm.my_obj.id}`;
console.log("Loading view at path: "+v);
vm.$router.push({ path: v });
},
...
}
It would print the expected log (e.g., Loading view at path: /foo/bar/112), however, the loading of data in the created() hook would not receive the value of route param. My failing created() code looked like below:
created: function() {
console.log("Loading object details.");
let vm = this;
let cid = vm.$route.params.id; // <---- This was the problem
vm.$http.get('api/'+cid)
.then(function (res) {
if (res.data.status == "OK") {
vm.my_obj = res.data.body;
} else {
vm.setStatusMessage(res.data.body);
}
})
.catch(function (error) {
console.log(error);
vm.setStatusMessage("Error: "+error);
});
}
The solution was indicated in the third note here quoted below :
Note: If the destination is the same as the current route and only
params are changing (e.g. going from one profile to another /users/1
-> /users/2), you will have to use beforeRouteUpdate to react to changes (e.g. fetching the user information).
I had to do the following in my component:
Change the line let cid = vm.$route.params.id; in created() to let cid = vm.course.id
and, add the following to the component:
beforeRouteUpdate(to, from, next) {
if (to.params.id) {
this.my_obj.id = to.params.id;
}
// Some other code specific to my app
next();
}
I hope this helps someone stuck with the similar issue.

If you want to send a parameter with a query parameter you can use that syntax like that
this.$router.push({
path: this.localePath(`/bookings/${requestReservation?.attributes?.booking_id}`),
query: { requestReservation: requestReservation }
})
You can access it on the next page like that
this.$route.query.requestReservation
If you want send it fro nuxt-link than its syntax like that
<nuxt-link
:to="{ path: '/bookings/'+ requestReservation.attributes.booking_id,
query: { requestReservation } }">
Booking
</nuxt-link>
You can access it on the next page same like previous
this.$route.query.requestReservation
