Answer 1

In your Blade file first, you need to convert string to array
#php
$staff = $assignment->staff_id;
$staff_ids = explode(",",$staff_name); //converted to array
print_r($staff_ids); //here you can check
#endphp
<td>
#foreach ($staff_ids as $value)
{{ $loop->first ? '' : ', ' }}
<span class="nice">{{ $value->name }}</span>
#endforeach
</td>

Personally id write a mutation on the assignment model, e.g.
getStaffNameAttribute()
{
return $this->staff()->first()->name;
}
which can be used like so
$assignment->staffName
but you could just do
$assignment->staff->first()->name;
I may be missing parenthesis in this.
Also this is only if you actually made them related... and not just manually entered in ID's in a column.... which i have a feeling you did...
EDIT
Showing how the many relation works.
On the assignment model you would have this
public function staff()
{
return $this->belongsToMany(Staff::class);
}
and on the staff model you would have
public function assignments()
{
return $this->belongsToMany(Assignment::class);
}
This relation would require a pivot table called assignment_staff with assignment_id and staff_id How you name the pivot tables are alphabetical order with singular names e.g. A comes before S so its assignment_staff not staff_assignment.
The reason its many to many as one assignment can have many staff and each staff can belong to many assignments.
