如何同时使用分页和查找位置？ （laravel 5.3）

Question

I using third party. I get from here : https://github.com/andersao/l5-repository

My function in file repository is like this :

public function displayList($year, $id = NULL)
{
    $clauses = ['year' => $year];
    if(isset($id)) {
        $clauses = array_merge($clauses, ['id' => $id]);
    }
    $query = Self::orderBy('programcode')
                 ->orderBy('accountcode')
                 ->findWhere($clauses)
                 ->paginate(1);
    return $query;
}

When executed, there exist error like this : Method paginate does not exist. .

I try remove ->findWhere($clauses) . It works. No error.

Findwhere and paginate apparently can not run simultaneously

Is there a solution to this problem?

Answer 1

It is because ->findWhere(...) ends the query with ->get() and returns the results (eloquent collection).

What you're trying to do is calling a ->paginate(...) method on an eloquent collection . It is actually a method on query builder .

Solution

applyConditions

$query = Self::orderBy('programcode')
             ->orderBy('accountcode')
             ->applyConditions($clauses)
             ->paginate(1);

Edit

Okay, so ->applyCondtions() does not return the object so you can't chain methods off of it. Try this:

$query = Self::orderBy('programcode')
    ->orderBy('accountcode');
$query->applyConditions($clauses);
$query = $query->paginate(1);

Answer 2

Like this:

$list = $this->repository->scopeQuery(function($query) use ($filterColumns) {

    return $query->where($filterColumns)->orderBy('created_at', 'DESC');

});

$list->paginate(10);
