There was an issue with rendering: "TypeError: Unable to access the 'name' property of an undefined object" [Vue alert]

I encountered the following error message:

TypeError: Cannot read property 'name' of undefined

Here's the snippet from the Vue file where the error occurred:

<tr v-for="user in fields.data" :key="user.id">
    <td>{{ user.id }}</td>
    <td>{{ user.name }}</td>
    <td>{{ user.email }}</td>
    <td>{{ user.password }}</td>
    <td>
        <a href="#" data-toggle="modal" data-target="#modal" @click="edit(user.id)">
            <span class="btn btn-primary">
                <i class="mdi mdi-edit"></i>
            </span>
        </a>
    </td>
</tr>

The corresponding script section is as follows:

edit(id) {
    this.users = this.fields[id];
    console.log(this.users);
},

Answer №1

If you encounter this error, it is likely due to attempting to access a property of an object that has not been created yet (often because it is generated asynchronously, such as with an API request). In this situation, you can instruct the template to wait for the object to be available using a v-if statement.

<template v-if="fields && fields.data">
  <tr v-for="user in fields.data" :key="user.id">
    <td>{{ user.id }}</td>
    <td>{{ user.name }}</td>
    <td>{{ user.email }}</td>
    <td>{{ user.password }}</td>
    <td>
      <a href="#" data-toggle="modal" data-target="#modal" @click="edit(user.id)">
            <span class="btn btn-primary">
                <i class="mdi mdi-edit"></i>
            </span>
      </a>
    </td>
  </tr>
</template>

It's important to note that the v-if cannot be placed on the same tag as the v-for directive.
