I wrote this query to get string type(value), which is up or down, instead it returns me an object.
$o_response = $this->statuses()
->where('status_id', $o_health_status->id)
->orderBy('created_at', 'desc')
->select('values')
->first();
this is the result :
{"values":"up","pivot":{"notification_id":1,"status_id":1,"values":"up","created_at":"2016-11-04 13:18:29","updated_at":"2016-11-04 13:18:29"}}
It returns an object instead of string. Why?
Laravel eloquent returns collection ex.->get() or object ex. ->first() .
So i think you will need just to get column something like
$o_response = $o_response->values;

I am trying to get a result set from a laravel eloquent query whereby I match a column against a list of values in an array.
$authenticated_operation_ids = AccessControl::where('user_id', '=', $user_id)
->where('entity_type_id', '=', $operation_entity_id)
->pluck('entity_access_id')->toArray();
$authenticated_operations = Operation::whereIn('id', $authenticated_operation_ids);
return view('page.index')->withOperations($authenticated_operations);
You can try it as:
$authenticated_operation_ids = AccessControl::where('user_id', '=', $user_id)->where('entity_type_id', '=', $operation_entity_id)->pluck('entity_access_id')->toArray();
$authenticated_operations = Operation::whereIn('id', $authenticated_operation_ids)->get();
return view('page.index')->withOperations($authenticated_operations);
Add get() at the end of the query.
1) pluck returns a single value from a single row. You want lists to get a single column from multiple rows. toArray may not be needed, as it returns an array of values
$authenticated_operation_ids = AccessControl::where('user_id', '=', $user_id)
->where('entity_type_id', '=', $operation_entity_id)
->lists('entity_access_id');
2) You're forgetting to actually retrieve the rows in your second line:
$authenticated_operations = Operation::whereIn('id', $authenticated_operation_ids)
->get();
You have to call get() function on the result set to obtain results. The modified code will be like
$authenticated_operation_ids = AccessControl::where('user_id', '=', $user_id)->where('entity_type_id', '=', $operation_entity_id)->get()->pluck('entity_access_id');
$authenticated_operations = Operation::whereIn('id', $authenticated_operation_ids)->get();
return view('page.index')->withOperations($authenticated_operations);
or you can use a cursor to process it.
I have a table called List which i planned to be displayed into view with this command : $lists= List::with('user', 'product.photodb', 'tagCloud.tagDetail')->get();. But, i want the data displayed is only those that has TagID equal to the one user inputted. Those data can be retrieved from TagCloud table.
What i am currently doing is :
$clouds = TagCloud::select('contentID')
->where('tagDetailID', '=', $tagID)
->get();
$lists = List::with('user', 'product.photodb', 'tagCloud.tagDetail')
->where('id', '=', $clouds->contentID)
->get();
But when i tried to run it, it only return a null value, even though when i am doing return $clouds, it does returned the desired ID.
Where did i do wrong ? Any help is appreciated !
A couple of gotchas with your current solution.
Using get() returns an Illuminate\Database\Eloquent\Collection object. Hence you can't use $clouds->contentID directly since $clouds is a collection (or array if you prefer). See Collection Documentation.
where(...) expects the third parameter to be a string or integer, aka single value. Instead, you are passing a collection, which won't work.
The correct way is to use whereHas() which allows you to filter through an eager loaded relationship.
Final Code:
$lists = List::with('user', 'product.photodb', 'tagCloud.tagDetail')
->whereHas('tagCloud',function($query) use ($tagID) {
return $query->where('contentID','=',$tagID);
})
->get();
See WhereHas Documentation.
What you want is whereHas()
$list = List::with(...)
->whereHas('relation', function($q) use($id) {
return $q->where('id', $id);
})->get();
Apply Where condition in you tagCloud model method tagDetail
public function tagDetail(){
return $q->where('id', $id);
}
This is my Laravel controller code
public function switchInfo($prisw, $secsw){
$cur_sw_pair_id = DB::table('sw_pairs')
->select('sw_pair_id')
->where('pri_sw','=',$prisw)
->where('sec_sw','=',$secsw)
->get();
$infolist = DB::table('cust_sw_pair')
->select('interface','pri_sw_vlan','sec_sw_vlan','pri_sw_admin_status','sec_sw_admin_status','description')
->where('sw_pair_id', '=', $cur_sw_pair_id)
->get();
return view('switchinfo.switchinfoview',compact('infolist'));
}
when this code executing it gives Object of class stdClass could not be converted to string error. How can i solve this? How can i pass my infolist into switchinfoview view without getting this error?
You can use pluck() to get value of a column.
Your first query should like this:
$cur_sw_pair_id = DB::table('sw_pairs')
->where('pri_sw','=',$prisw)
->where('sec_sw','=',$secsw)
->pluck('sw_pairs');
Keep the second query as it is.
Hope it will help.
The issue is that ->get() returns a collection, which is a 0-indexed collection of results (rows) from the database. In your case, you want to be using the following query:
$cur_sw_pair_id = DB::table('sw_pairs')
->select('sw_pair_id')
->where('pri_sw','=',$prisw)
->where('sec_sw','=',$secsw)
->first();
And then accessing the property sw_pair_id of $cur_sw_pair_id, like so:
$infolist = DB::table('cust_sw_pair')
->select('interface','pri_sw_vlan','sec_sw_vlan','pri_sw_admin_status','sec_sw_admin_status','description')
->where('sw_pair_id', '=', $cur_sw_pair_id->sw_pair_id)
->first();
Then, in your view, you can access all the properties (anything in the ->select() statement) of $infolist using $infolist->PROPERTY_HERE
Note that using ->first() is essentially using the same as ->get();, but you have to access the results of ->get() using an index, so
$cur_sw_pair_id[0]->sw_pair_id
Hope that provides some insight for you.
I have next query in Laravel Eloquent:
$buildings = Building::select('buildings.*')->join(
DB::raw('('.
(
IngameBuilding::select('buildings.building_id', 'buildings.level')
->join('buildings', 'buildings.id', '=', 'ingame_buildings.building_id')
->toSql()
).
') as `added_buildings`'), 'added_buildings.building_id', '=', 'buildings.building_id')
->where('buildings.level', '>', 'added_buildings.level')
->get();
This query returns all allowed rows from base, but one row more. When I added DB::raw() in where() return values is valid.
Good-working code:
$buildings = Building::select('buildings.*')->join(
DB::raw('('.
(
IngameBuilding::select('buildings.building_id', 'buildings.level')
->join('buildings', 'buildings.id', '=', 'ingame_buildings.building_id')
->toSql()
).
') as `added_buildings`'), 'added_buildings.building_id', '=', 'buildings.building_id')
->where('buildings.level', '>', DB::raw('`added_buildings`.`level`'))
->get();
Why first code workig, hmm.. Wrong?
I'm not a big fan of Laravel at all.
I've got only small experience with this framework but i'm almost sure that where function accepts only a 'constant' values to be checked against.
If you'll get an output of this query using toSQL method on the query object you will see that eloquent will convert it as something like:
(...) where buildings.level > 'added_buildings.level'
so the condition checks if the buildings.level (whatever the type is)
is greater than the given string and not the column value.
Using the DB::raw you're getting the proper sql as the eloquent won't parse/convert it.
You would need to use whereRaw method I suppose.

I get some values from laravel query builder. I would like to get and set these values into somewhere of my code. So i get undefined index exception message with the following codes :
laravel query :
$generatedRowValue = DB::table('myTableName')
->where('id', '=', 'someValue')
->where('anyOtherValue', '=', 'anotherValue')
->get();
I want to reach the values set in $generatedRowValue variable.
P.S. : Yeah i can get the values from the query, checked it out with var_dump(); dd(); etc. and i know my values are not undefined.
I'm new on this platform so i don't know how to reach these values.
Any help would be appreciated.
---UPDATE---
This is a simple HTML file which includes php partially.
<?php
$html = new simple_html_dom();
$html->load('<input type="text" value="'.$generatedRowValue['thevalueName'].'">')
?>
So i need $generatedRowValue['thevalueName'] 's value.
get() returns an array of objects. I think you want to use first() instead since you only expect one result.
$generatedRowValue = DB::table('myTableName')
->where('id', '=', 'someValue')
->where('anyOtherValue', '=', 'anotherValue')
->first();
By the way, you can also use the object syntax in your view (if you want)
$generatedRowValue->thevalueName
