How to show nested array data in vuejs component

Question

I'm running the following query: $users=User::with('roles.permissions')->get()->unique();

this query returns result set:

Array = [
{
    created_at: "2019-01-11 09:27:02",
    deleted_at: null,
    email: "[email protected]",
    email_verified_at: null,
    id: 1,
    name: "ADMIN",
    roles: [
        {id: 1, name: "Admin", slug: "Admin", description: "This is Super-Admin Role", created_at: "2019-01-11 09:27:02",
      permissions: [
       {id:1, name:"Create,slug:"Create"},
       {id:1, name:"Read",slug:"Read"},
       {id:1, name:"Delete",slug:"Delete"},
],
},

    ],
},

]

returns user details with roles I want to show this result set in my Vue Component table.

this my vue component read method

  read:function(){
        axios.get('/userlist')
        .then(response=>{
            console.log(response.data);

        })

    }

This is my table

<table class="table table-bordered">
  <thead>
    <th>no.</th>
    <th>Name</th>
    <th>E-mail</th>
    <th>Roles</th>
    <th>Permissions</th>
    <th>Action</th>
  </thead>
  <tbody>
    <tr v-for="(user,key) in users">
      <td>{{++key}}</td>
     </tr>
   </tbody>
</table>

How to show user,roles and permissions separately in html table.

<table class="table table-bordered"> <thead> <th>no.</th> <th>Name</th> <th>E-mail</th> <th>Roles</th> <th>Permissions</th> <th>Action</th> </thead> <tbody> <tr v-for="(user,key) in users"> <td>{{++key}}</td> </tr> </tbody> </table> — Gabrielle-M

You should store your API result in your component data. But you need to prepare your component data to receive your users.

data() {
  return {
     users: []
  }
}

Now, you should make your function update this brand new data.

read:function(){
    axios.get('/userlist')
    .then(response=>{
        this.users = response.data;
    })

}

Now, I assume that you want to display user's roles as a concatenated string. Then, you need a function to do this.

methods: {
    getRoles: function(roles) {
        let rolesString = ''

        roles.forEach((role, index) => {
            if (index != 0)
                rolesString += ', '
            rolesString = rolesString + role.name
        })
        return rolesString
    },
    getPermissionsFromRoles: function(roles) {
        let permissionsList = []

        roles.permissions.forEach((permission) => {
            if (permissionsList.indexOf(permission.name) != -1) {
                permissionsList.push(permission.name)
            }
        })
        let permissionsString = ''
        if (permissionsList.length > 0) {
            permissionsList.forEach((permission, index) => {
                if (index != 0)
                    permissionsString += ', '
                permissionsString += permission
            })
        }
        return permissionsString
    }
}

Then, you can use this function in your template to handle your user roles.

<table class="table table-bordered">
  <thead>
    <th>no.</th>
    <th>Name</th>
    <th>E-mail</th>
    <th>Roles</th>
    <th>Permissions</th>
  </thead>
  <tbody>
    <tr v-for="(user,key) in users">
      <td>{{key}}</td>
      <td>{{user.name}}</td>
      <td>{{user.email}}</td>
      <td>{{getRoles(user.roles)}}</td>
      <td>{{getPermissionsFromRoles(user.roles)}}</td>
     </tr>
   </tbody>
</table>

sorry, I forgot to get the role name. Try again, please. rolesString = rolesString + role.name
<td>{{getPermissions(user.roles.permissions)}}</td> I've tried this. and write the getPermissions() as like getRoles() but it's shows TypeError.
You didn't send your permission data, could you edit your post, please?

rendering in the template will look like:

<td v-for="role in roles">{{role}}</td>

you will also need to have roles in your data:

data() {
  return {
     roles: []
  }
}

and finally make your function update the data

function(){
   .then(response=>{
      this.roles = response.data
        })

}
