Laravel eloquent query order by customized field - laravel

Question

I have this raw mysql query
SELECT campaign_influencers.*,
CASE influencer_status
WHEN 'PENDING' THEN 0
WHEN 'ACTIVE' THEN 1
WHEN 'LIVE' THEN 2
WHEN 'ACCEPTED' THEN 3
ELSE 5
end AS order_field
FROM campaign_influencers
WHERE campaign_id = 612
ORDER BY order_field
How can this be converted to eloquent query builder?
This is what I have done so far.
$sql = "SELECT campaign_influencers.*,
CASE influencer_status
WHEN 'PENDING' THEN 3
WHEN 'ACTIVE' THEN 1
WHEN 'LIVE' THEN 2
WHEN 'ACCEPTED' THEN 0
ELSE 5
end AS order_field
FROM campaign_influencers
WHERE campaign_id = :campaignId
ORDER BY order_field";
$campaignInfluencers = DB::select( DB::raw($sql), array(
'campaignId' => $id
));
Only issues is that the relationship object is gone.
foreach ($campaignInfluencers as $campaignInfluencer) {
$user = $campaignInfluencer->user; //will not work
}

Answer 1

Use this:
CampaignInfluencer::select('*', DB::raw('CAST influencer_status ... AS order_field'))
->where('campaign_id', $campaign_id)
->orderBy('order_field')
->get();

Answer 2

You could shorten your query by using FIND_IN_SET
SELECT campaign_influencers.*,
FIND_IN_SET(influencer_status,'ACCEPTED,LIVE,ACTIVE,PENDING') AS order_field
FROM campaign_influencers
WHERE campaign_id = 612
ORDER BY order_field DESC
Using eloquent as #Jonas Staudenmeir already suggested you need to use raw method for raw sql expressions
YourModel::select('*', DB::raw("FIND_IN_SET(influencer_status,'ACCEPTED,LIVE,ACTIVE,PENDING') AS order_field"))
->where('campaign_id', 612)
->orderBy('order_field', 'desc')
->get();
