I'm grabbing some data in Laravel using the find method and only grabbing the id's I want:
$my_ids = array(1,4,5,10);
$results = Model::find($my_ids);
However, if I try to paginate via Model::find($my_ids)->paginate(10), it throws the error: Call to undefined method Illuminate\Database\Eloquent\Collection::paginate().
How can I query to only get specific model Id's back from the database while also using pagination?
Turns out I can use this syntax:
$results = Model::whereIn('id', $my_ids)->paginate(10);
I suggest use the eloquent query builder:
$results = Model::whereIn('id', $my_ids)->paginate(10);

normally i use this:
$users = \App\Users::where('age', '>=', '20')->paginate(20);
But if I use raw querys or use the get(); method from querybuilder, I got an array not a collection or a paginator instance as result.
How can I get my ->links(); from that array result?
Hope all is explained well. :-)
KR,

Write{{ $users->links() }} in your view page. According to your query, pagination will show while your data return more than 20 rows.
For better understand Read this doc
I am new to laravel. I am trying to keep a where clause for the get method like this.
$employees = newdb::where('status', 'Active');
$response = $employees;
return response()->json($response,200);
But i am getting No Properties as output
In PHP I used this
"SELECT * FROM newdb WHERE status = 'Draft'";
What am i doing wrong? I tried different suggestions But none worked correctly. How do i do this? What is wrong with my code?
where method returns Builder object. So, you have to call get method on it to fetch data.
Try this
$employees = newdb::where('status', 'Active')->get();
return response()->json($employees, 200);
I'm using Laravel Lumen to build an API.
I've come to a point where I need to find out what SQL query is being generated by Eloquent. I know how to do this in Laravel 4 and Laravel 5 but i've tried the same code in Lumen and the query is blank?
$queries = DB::getQueryLog();
$last_query = end($queries);
echo 'Query<pre>';
print_r($last_query);
exit;
The above code, when run in Laravel works fine - in Lumen the query is blank?
To get the query log in Laravel Lumen working you need to enable it:
DB::connection()->enableQueryLog();
You can add that code in to your controller, middleware, etc then use:
$queries = DB::getQueryLog();
$lastQuery = end($queries);
dd($lastQuery)
To print your query.
You can also use the following with eloquent:
$myModel = Users::where('active', true);
dd($myModel->getSql(), $myModel->getBindings());
You must run the getSql() and getBindings() before you call ->first() or ->get(), etc
Just call this after the query to keep it quick and simple:
echo $query->toSql();
I want to update all my records where the name is like the one im referencing it.
However im getting an error saying Call to undefined method save()
Here's my code
$section = Section1::where('name', 'like', 'ss123')->get();
$section->name = Input::get('name');
Please help :(
$section = Section1::where('name', 'like', 'ss123')->get() returns a collection (think of an array).
Therefore you should loop through the collection using foreach and apply the save to each object in the collection, as such:
foreach($section as $s)
{
$s->name = Input::get('name');
$s->update();
}
Then again this ain't very DB-friendly.
Therefore, the most appropriate action in your case will be a mass update:
Section1::where('name','like','ss1213')->update(['name'=>Input::get('name')]);
try dd($section) and find the available method to prevent call the undefined method.
I assume you are using $section->save();
if you want to update,
use $section->touch();
or $section->update(array('name' => Input::get'name'));
I am new to Laravel and am using version 4.1.
I am attempting to query database using pagination and then run the results through the appends() function to add additional parameters to my URL.
Here is the code I am using
$query = DB::table('tableName');
$query->paginate(50);
$results = $query->get();
And that runs as desired. Now when I attempt to create the pagination list (Bootstrap default) and run the following code I get an error.
$pagination = $results->appends(array('key' => 'value'))->links();
This is the error I receive.
Call to a member function appends() on a non-object
I know I'm doing something wrong, I just can't figure out what...
Thanks in advance,
SC
I'm not familiar with the appends function, but you do have an error I can see. Try changing
$query = DB::table('tableName');
$query->paginate(50);
$results = $query->get();
To...
$query = DB::table('tableName');
if(Input::has('someinput')) {
$query->where('someinput', Input::get('someinput'));
}
if(Input::has('otherinput')) {
$query->where('otherinput', Input::get('otherinput'));
}
$results = $query->paginate(50);
Once you run paginate(), an instance of Paginator is returned. I don't see a get() method for Paginator though so I'm not sure how you weren't getting an error there.
