Laravel - query depending on user - php

Question

In Laravel I have a scenario in which different users can go to a view blade where they can see posts they have created.
At the minute I'm just passing in all the data, but I'm wondering how to pass data to a view depending on the user.
E.g if I'm a root user I get to see everything so like
Post::get()
Then
return view('someview', compact('post')
Which would return the posts
Essentially what Im trying is something like this...
if(user->role = their role) then you get query 1 else you get query 2
Do you think this is acheivable using conditional query scopes?
UPDATE
Is this a horrible solution?
if($user->department == "Loans")
{
echo "you are from loans FAM";
$articles = Article::where('department', '=', 'Loans')->get();
}
else if($user->department == "Digital")
{
echo "you are from digital FAM";
$articles = Article::where('department', '=', 'Digital')->get();
}
else if($user->department == "Consulting")
{
echo "you are from Consulting FAM";
$articles = Article::where('department', '=', 'Consulting')->get();
}

Answer 1

You could achieve that with a query scope if you wanted to. Something like this:
class Post extends Model
{
// ...
public function scopeByUser($query, User $user)
{
// If the user is not an admin, show only posts they've created
if (!$user->hasRole('admin')) {
return $query->where('created_by', $user->id);
}
return $query;
}
}
Then you can use it like this:
$posts = Post::byUser($user)->get();
In response to your update:
class Article extends Model
{
// ...
public function scopeByUser($query, User $user)
{
// If the user is not an admin, show articles by their department.
// Chaining another where(column, condition) results in an AND in
// the WHERE clause
if (!$user->hasRole('admin')) {
// WHERE department = X AND another_column = another_value
return $query->where('department', $user->department)
->where('another_column', 'another_value');
}
// If the user is an admin, don't add any extra where clauses, so everything is returned.
return $query;
}
}
You would use this in the same kind of way as above.
Article::byUser($user)->get();
