调研方向

从 Model::paginate() 入口点开始,使用 24 行和第 10 页,通过提供的 load_more() 示例复现该行为。检查生成的查询是否保留了请求的偏移量;完成标准是:即使第 10 页没有记录,也会生成 LIMIT 80, 8。

What happened?

When i paginate the model like this $UsersMode->orderBy('id_user', 'ASC')->paginate(8, 'group', $page_number);

returns "SELECT * FROM users ORDER BY id_user ASC LIMIT 8, 8" based on offset and per page number

But my total count rows in the table are 24, so when i reach the end 16, 8 it returns me the same query as the last existing page in my database even with $page_number = 100

Steps to Reproduce
	public function load_more($page_number = 2)
	{
		$UsersModel 	= new UsersModel();
		
		$this->ViewData['Page'] = $page_number;
		
		$this->ViewData['Users'] = $UsersMode->orderBy('id_user', 'ASC')->paginate(8, 'group', $page_number);

		echo $UsersModel->db->getLastQuery();
	}

returns "SELECT * FROM users ORDER BY id_user ASC LIMIT 8, 8"

But my total count rows in the table are 24, so when i reach the end 16, 8 $page_number = 10 and go to a page number more than 3 it returns the same query "SELECT * FROM users ORDER BY id_user ASC LIMIT 16, 8"

Expected Output

Going to a page number more than the total count rows of my table it should return the propper offset even if i have the total rows less than the per page number or less than the total count

$page_number = 10 it should returns the query "SELECT * FROM users ORDER BY id_user ASC LIMIT 80, 8" even if i don't have enough records in my database table

Anything else?
