Laravel Eloquent selecting field from relationship after joining with other tables - php

Question

I have a query where I have joined several tables together and as they have fields with identical names I have used the select query to only pick out the fields that I require. However, i also need to include the results obtained from the with query but I do not know how to specify it in the select query.
$display_tickets = ManualTicket::select('u.name as name', 'i.name as initiator', 'manual_tickets.status as status', 'manual_tickets.description as description', 'manual_tickets.location as location', 'manual_tickets.created_at as created_at', 'manual_tickets.initiator_id as initiator_id', 'manual_tickets.id as manual_ticket_id','manual_tickets.manual_ticket_log as manual_ticket_log_id')
->leftJoin('users as u', 'u.id', '=', 'manual_tickets.user_id')
->leftJoin('users as i', 'i.id', '=', 'manual_tickets.initiator_id')
->where(function ($checkClients) use($target_client_id){
$checkClients->where('u.client_id', '=', $target_client_id)
->orWhere('i.client_id', '=', $target_client_id);
})
->whereBetween('manual_tickets.created_at', [$start_date->toDateString(), $end_date->addDays(1)->toDateString()])
->with('manual_ticket_log')
->orderBy("created_at", "DESC")->get();
I tried to include the manual ticket logs through the use of the code below but it says that there is no such field in the manual ticket table.
'manual_tickets.manual_ticket_log as manual_ticket_log_id')
In short, how can i include the results of the with relationship from ->with('manual_ticket_log') into the select statement
--EDIT-- (Tried to replace join with with queries)
However there appears to be any error with my SQL query which i believe stems from the whereHas portion of the code which results in this error being shown.
strtolower() expects parameter 1 to be string, object given
$display_tickets = ManualTicket::select('*')
->with('user')
->with('initiator')
->with('manual_ticket_log')
->where(function ($checkClients) use($target_client_id){
$checkClients->whereHas('user', function ($checkClient) use($target_client_id){
$checkClient->where('client_id', '=', $target_client_id);
})
->orWhere($checkClients->whereHas('initiator', function ($checkClient2) use($target_client_id){
$checkClient2->where('client_id', '=', $target_client_id);
}));
})
->whereBetween('manual_tickets.created_at', [$start_date->toDateString(), $end_date->addDays(1)->toDateString()])
->orderBy("created_at", "DESC")->get();

Answer 1

you should join that table to get fields form:
$display_tickets = ManualTicket::select('u.name as name', 'i.name as initiator', 'manual_tickets.status as status', 'manual_tickets.description as description', 'manual_tickets.location as location', 'manual_tickets.created_at as created_at', 'manual_tickets.initiator_id as initiator_id', 'manual_tickets.id as manual_ticket_id','manual_tickets.manual_ticket_log as manual_ticket_log_id',
'manual_tickets.manual_ticket_log as manual_ticket_log_id')
->leftJoin('users as u', 'u.id', '=', 'manual_tickets.user_id')
->leftJoin('users as i', 'i.id', '=', 'manual_tickets.initiator_id')
->leftJoin('manual_ticket_logs',function ($join){
$join->on('manual_ticket_logs.manual_ticket_id', '=', 'manual_tickets.id')
->on('manual_ticket_logs.id', '=', \DB::raw("(select max(id) from manual_ticket_logs WHERE manual_ticket_logs.manual_ticket_id = manual_tickets.id)"));
})
->where(function ($checkClients) use($target_client_id){
$checkClients->where('u.client_id', '=', $target_client_id)
->orWhere('i.client_id', '=', $target_client_id);
})
->whereBetween('manual_tickets.created_at', [$start_date->toDateString(), $end_date->addDays(1)->toDateString()])
->with('manual_ticket_log')
->orderBy("created_at", "DESC")->get();
please make sure of the fields names in the newest join clause.

You can take advantage of Laravel relationships to make the code more readable and avoid an expensive leftJoin:
$display_tickets = ManualTicket::select('*')
->with([ 'user', 'initiator', 'manual_ticket_log' ])
->where(function ($checkClients) use($target_client_id){
$checkClients->whereHas('user', function ($checkClient) use($target_client_id){
$checkClient->where('client_id', '=', $target_client_id);
})->orWhereHas('initiator', function ($checkClient2) use($target_client_id){
$checkClient2->where('client_id', '=', $target_client_id);
}));
})->whereBetween('created_at', [$start_date->toDateString(), $end_date->addDays(1)->toDateString()])
->orderBy("created_at", "DESC")
->get();

You can try this
$display_tickets = ManualTicket::select('u.name as name', 'i.name as initiator', 'manual_tickets.status as status', 'manual_tickets.description as description', 'manual_tickets.location as location', 'manual_tickets.created_at as created_at', 'manual_tickets.initiator_id as initiator_id', 'manual_tickets.id as manual_ticket_id','manual_tickets.manual_ticket_log as manual_ticket_log_id')
->leftJoin('users as u', 'u.id', '=', 'manual_tickets.user_id')
->leftJoin('users as i', 'i.id', '=', 'manual_tickets.initiator_id')
->where(function ($checkClients) use($target_client_id){
$checkClients->where('u.client_id', '=', $target_client_id)
->orWhere('i.client_id', '=', $target_client_id);
})
->whereBetween('manual_tickets.created_at', [$start_date->toDateString(), $end_date->addDays(1)->toDateString()])
->with(['manual_ticket_log' => function($query) {
$query->select('field1', 'field2');
}])
->orderBy("created_at", "DESC")->get();
Or do this like
->with('manual_ticket_log:field1, field2')
