The relationship between gwrcategory and gwrproces is one to many. Between gwrproces and gwrlist is many to one.
I use this code to search in the data. I use % for now to find everything until this works.
$searchresult = GwrCategory::
whereHas('gwrproces', function($query) use ($request){
$query->where('gwr_code', 'LIKE', '%'.$request->input('gwrcode').'%')->
whereHas('gwrlist', function($query) use ($request)
{
$query->where('versie', 'LIKE', '%');
}
)->with('gwrlist')->get();
}
)->with('gwrproces')->get();
The resulting sql of the code above is:
select * from `gwr_proces`
where `gwr_proces`.`gwr_category_id` = `gwr_categories`.`id` and `gwr_code` LIKE %20%
and exists
(select * from `gwr_lists`
where `gwr_proces`.`gwrlist_id` = `gwr_lists`.`id` and `versie` LIKE %)
This gives an error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'gwr_categories.id' in 'where clause'.
I've played around with the query in phpmyadmin and this seems to get it working. I only added gwr_categories
to the first select * from.
select * from `gwr_proces`,`gwr_categories`
where `gwr_proces`.`gwr_category_id` = `gwr_categories`.`id` and `gwr_code` LIKE '%'
and exists
(select * from `gwr_lists`
where `gwr_proces`.`gwrlist_id` = `gwr_lists`.`id` and `versie` LIKE '%')
My question is: how can I convince eloquent to add the correct column or rewrite the code to get it to search in gwrproces and gwrlist tables for a specific text in a column while keeping the relationship with categories in-tact?
Edit: I use eager loading, hence the with()->get()
The problem is that you execute the nested query.
You also can't use eager loading like that.
Remove ->with('gwrlist')->get()
.
