Dynamic Buttons in Navigation Bar using Vuetify

Question

I have a problem... My VueJS Application using Vuetify. I have a <v-toolbar>, and on the right, I want to place some buttons that change depending on the component shown in <router-view>, but i can't access to component properties from $route or $route for get objects and methods bind to model of my component.

I would like to know if there is any way to assign a model to from my main component.

I have tried with "named-routes" but I do not know what is the way that properties can be shared between components that are managed by an <router-view> and updated live.

In resume:

I have my application skeleton with a navigation bar, additionally in the dynamic content I have a <router-view>. Depending on the component that is displayed in <router-view>, I would like to see buttons in the navigation bar corresponding to that component, which interact and change the data or execute methods of the component.

App.vue

<template>
  <v-app>
		<router-view></router-view>
  </v-app>
</template>

<script>
	export default {
		name: 'App',
		data() {
			return {
				
			};
		}
	};
</script>

index.js (router)

import Vue from 'vue'
import Router from 'vue-router'
import AppLogin from '@/components/AppLogin'
import Skeleton from '@/components/Skeleton'
import ShoppingCart from '@/components/ShoppingCart'
import ShoppingCartButtons from '@/components/ShoppingCartButtons'
import ProductSelection from '@/components/ProductSelection'
import ProductSelectionButtons from '@/components/ProductSelectionButtons'
import ProductDetail from '@/components/ProductDetail'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path : '/login',
      name : 'AppLogin',
      component : AppLogin
    },
    {
      path : '/app',
      name : 'Skeleton',
      component : Skeleton,
      children : [{
          path : 'shopping-cart',
          components : {
            navigation : ShoppingCart,
            navButtons : ShoppingCartButtons
          }
        }, {
          path: 'product-selection',
          name : 'ProductSelection',
          components : {
            navigation : ProductSelection,
            navButtons : ProductSelectionButtons
          }
        },
        {
          path: 'product-detail',
          name : 'ProductDetail',
          components : {
            navigation : ProductDetail
          },
          props : true
        }
      ]
    }
  ]
})

	};
  },
  name: "Skeleton"
};
</script>

EDITED

My solution is create a new component Toolbar and add slots for buttons to right and left.

<template>
    <div>
        <v-navigation-drawer persistent :mini-variant="false" :clipped="true" v-model="drawer" enable-resize-watcher fixed app>
            <v-list>
                <v-list-tile value="true" v-for="(item, i) in items" :key="i" :replace="true" :to="item.path">
    
                    <v-list-tile-action>
                        <v-icon v-html="item.icon"></v-icon>
                    </v-list-tile-action>
    
                    <v-list-tile-content>
                        <v-list-tile-title v-text="item.title"></v-list-tile-title>
                    </v-list-tile-content>
                </v-list-tile>
            </v-list>
        </v-navigation-drawer>
    
        <v-toolbar app :clipped-left="true" color="primary" :dark="true" flat>
    
            <v-toolbar-side-icon v-if="showDrawer" @click.stop="drawer = !drawer">
            </v-toolbar-side-icon>

            <v-toolbar-side-icon v-if="!!back" @click="back">
                <v-icon>keyboard_backspace</v-icon>
            </v-toolbar-side-icon>
            
            <v-toolbar-title v-text="title" style="font-size: 1.4em"></v-toolbar-title>
            <v-spacer></v-spacer>
            <v-card-actions>
                <slot name="right"></slot>
            </v-card-actions>
    
        </v-toolbar>
        <v-snackbar
            :timeout="5000"
            :top="true"
            :multi-line="true"
            :vertical="true"
            v-model="snackbar.show"
            >
            {{ snackbar.content }}
            <v-btn flat color="white" @click.native="snackbar.show = false">Cerrar</v-btn>
        </v-snackbar>
    </div>
</template>

<script>
    export default {
        name: 'app-toolbar',
        props: ['title','showDrawer', 'back'],
        data() {
            return {
                drawer : false,
                items: [{
                    icon: "shopping_cart",
                    title: "Carrito de Compras",
                    path: "/carrito-compras"
                }, {
                    icon: "attach_money",
                    title: "Facturas",
                    path: "/documentos-tributarios"
                }, {
                    icon: "account_balance_wallet",
                    title: "Presupuestos"
                }, {
                    icon: "insert_chart",
                    title: "Informes"
                }, {
                    icon: "local_offer",
                    title: "Productos"
                }, {
                    icon: "person",
                    title: "Clientes"
                }, {
                    icon: "layers",
                    title: "Cuenta"
                }, {
                    icon: "comment",
                    title: "Comentarios"
                }, {
                    icon: "settings",
                    title: "Ajustes"
                }]
            };
        },
        computed : {
            snackbar() {
                return this.$store.getters.snackbar;
            }
        }
    }
</script>

and use is:

 <app-toolbar title="Carrito de Compras" :showDrawer="true">
    <template slot="right">
        <v-toolbar-side-icon @click="confirm">
            <v-icon>monetization_on</v-icon>
        </v-toolbar-side-icon>

    </template>
</app-toolbar>

Answer 1

I guess it's a time for a more up-to-date answer.

For my requirement to dynamically modify the item list in the app-bar based on the selected view, the solution was to use the Named Views

Answer 2

I had the same problem, My solution was manage the left button action from de meta of vue router like this:

    {
      path: '/feedstocks/:categoryId/:id',
      name: 'Feedstock',
      component: () =>
        import(
          /* webpackChunkName: "client-chunk-feedstock-details" */ '@/views/FeedstockDetails.vue'
        ),
      props: true,
      meta: {
        authNotRequired: true,
        backRoute: 'Material'
      }
    }

Then I'm able to check that metadata in app bar button action:

<v-app-bar app color="primary" dark>
  <v-btn text icon color="white" @click="leftButtonAction">
    <v-icon>{{ leftButtonIcon }}</v-icon>
  </v-btn>
  <v-toolbar-title>
    {{ currentAppTitle }}
  </v-toolbar-title>
  <v-spacer></v-spacer>
</v-app-bar>

leftButtonIcon() {
  if (this.$route.meta.backRoute) {
    return 'mdi-chevron-left'
  }
  return 'mdi-menu'
}

leftButtonAction() {
  if (this.$route.meta.backRoute) {
    this.$router.push({ name: this.$route.meta.backRoute })
  } else {
    this.toggleDrawer()
  }
}

Answer 3

If you are using Vuex, you can use vuex-router-sync, then you can access the route from any component with this.$state.route.path.

If not, Scott's answer is probably the best way to do it.

Answer 4

I did the same thing as you in a recent project and found altering the structure was the easier way to fix issues like this.

My structure was as follows:

app.vue: Only contains <router-view> no other components

router.js: Parent route is a layout component, all sub routes which contains my toolbars and other layout components and it's own <router-view> which receives child routes

ex:

{
  path: '/login',
  name: 'Login',
  component: load('login')
},
{
  path: '/',
  component: load('main-layout'),
  children: [
    {
      path: '',
      name: 'Home Page',
      component: load('homePage')
    },
    {
      path: '/settings',
      name: 'Settings',
      component: load('settings'),
    }
  ]
}

Now in your main-layout:

computed: {
  showHomeButton () {
    if (this.$route.path === '/') {
      return true
    }
    return false
    // Repeat for other routes, etc...
  },
}
