Unable to reference a property or method in Vue.js and Vuetify due to an issue with the <v-btn-toggle> button causing an error

Just started using vuetify and exploring the <v-btn-toggle> component for the first time.

I'm trying to implement a toggle feature to filter my user list based on employee, manager, or admin types...

Check out a snippet of my code below:

<v-btn-toggle
        v-model="toggle_user"
        multiple
        >
        <v-btn :value="employee">
            Employees
        </v-btn>
        <v-btn :value="manager">
            Managers
        </v-btn>
        <v-btn :value="admin">
            Admins
        </v-btn>
        </v-btn-toggle>
data() {
    return {
        toggle_user: 1,
    }
},

To display the result on the page, I used:

<p>{{toggle_user}}</p>
and it correctly displays an array based on selected values...

However, every time I click one of the buttons, I encounter the following error:

Property or method ["employee" or "manager" or "admin"] is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.

Can you spot what's wrong with my code?

Your help would be greatly appreciated! Have a wonderful day!

Answer №1

The error message clearly indicates that there is some data that has been referenced during render without being defined first.

To resolve this issue, you can try the following code snippet and check if it provides the desired outcome:

<script>
export default {
    data() {
        return {
            toggle_user:1,
            employee: "employee",
            manager: "manager",
            admin: "admin",
        };
    },
};
</script>
