Django 페이지네이션 구현 코드

Params

        limit = int(request.query_params.get('limit', '15'))
        page = int(request.query_params.get('page', 1))
        offset = max(page -1, 0 ) * limit
        next_offset = max(page, 1) * limit

 

Use offset

Use offset for list slicing if there are objects or lists

        # You Can use this pattern to objects or another list
        review_list = [review for owner_place in owner_places for review in owner_place._places.review_list] 
        current_review_list = review_list[offset: offset + limit]
        next_review_list = review_list[next_offset: next_offset + limit]

 

NextUrl

        next_url = None
        if next_review_list:
            next_url = request.build_absolute_uri().split('?')[0] + '?'
            next_url += f'page={page + 1}'
            next_url += f'&limit={limit}'

 

Return

        return Response(
            dict(
                next=next_url,
                review_list=current_review_list
            )
        )
