Trying to get property of non object

Why are you trying to do a DB query in the view?

It could work, but its bad practice.

Assuming you have a relationship between Roleuser model and User model then you should eager load in the controller;

  public function edit($id){
        $find=Roleuser::with('user')->find($id);
        return view('admin.role.roleupdate',compact('find'));
    }

and then in the view, you can use {{ $find->user->name }}

@Snapey How to write this relationship in the model?

I don't know? please describe the relationship

@Snapey I wrote the following model user

public function roleuser()
    {
        return $this->hasOne(Roleuser::class);
    }

model roleuser

    public function user()
    {
        return $this->belongsTo(User::class);
    }

it's true؟

They look ok, provided roleusers table has a user_id column and the primary key of the users table is id

@Snapey This is my table

user

id----name---username

role

id-----types

roleuser

id---user_id---role_id----active

The error below

Trying to get property of non object

I assume in your models then you have needed to specify the table name since by convention they should be plural (users, roles, roleusers)

What line gives the error?

@Snapey As follows

protected $table = 'user';

ok.

what line gives the error

@Snapey error:

Trying to get property of non-object 

line:

$find->user->name

@Snapey where is the problem from

@Snapey problem : in view

$find->user->name

So the error is saying that this Roleuser does not have a user

Is your data setup ok with the correct relationships?

Try this;

  public function edit($id){
        $find=Roleuser::with('user')->find($id);

    dd($find);

        return view('admin.role.roleupdate',compact('find'));
    }

When the dump appears, expand the relations section and check that it contains the user

u can use optional() helper

{{optional($find->user)->name}}

@rin4ik error:

@Snapey I wrote the following model user

public function roleuser()
    {
        return $this->hasOne(Roleuser::class);
    }

model roleuser

    public function user()
    {
        return $this->belongsTo(User::class);
    }

You said already... What has that got to do with it?

It does not tell me that you actually have related models in the database tables.

ie, user with id=1 and roleuser with user_id=1

@Snapey This is my table

user

id----name---username

role

id-----types

roleuser

id---user_id---role_id----active

I give up

@Snapey where is the problem from?

Look, I'll put this as simply as I can

DO YOU HAVE ANY DATA IN THE DATABASE !!!

yes, I'm shouting

@Snapey Yes - I have information in any database

Lets loop back so that you get chance to read it again...

So the error is saying that this Roleuser does not have a user

Is your data setup ok with the correct relationships?

Try this;

  public function edit($id){
        $find=Roleuser::with('user')->find($id);

    dd($find);

        return view('admin.role.roleupdate',compact('find'));
    }

When the dump appears, expand the relations section and check that it contains the user

@Snapey null return

So you cannot find the Roleuser with the $id ?What id was passed into edit? Do you have a row in the roleuser table with the id that was passed?

Are you trying to edit the user, or the role?

public function edit($id){
        $find=Roleuser::find($id);

That's getting the role by the $id passed in... not the user.

@Cronix Just edit the role

Then why do you care about the user?

Wow ... this is like a skit on SNL.
