# Since I keep on forgetting how to create Python @dataclass with static field and how to reference the class within the class....

# Example:
from dataclasses import dataclass
from typing import Dict, ClassVar

@dataclass
class NotionPage:
    page_id: str
    last_edited_time: str
    url: str
    title: str

    pages_by_key: ClassVar[Dict[str, 'NotionPage']] = {}

    def __str__(self):
        return f"title:{self.title} | last_edited:{self.last_edited_time} | url:{self.url}"

    def record_page_by_key(self) -> bool:
        page_key = self.title + ' ' + self.last_edited_time
        if page_key in NotionPage.pages_by_key:
            return False
        else:
            NotionPage.pages_by_key[page_key] = self

        return True

    @staticmethod
    def instantiate_page_from_page_info(page_info):
        page_id = page_info['id']
        last_edited_time = page_info['last_edited_time']
        url = page_info['url']
        titles = page_info['properties']['Name']['title']
        if len(titles) > 1:
            print(f'ERROR: {url} has more than one title')
        title = page_info['properties']['Name']['title'][0]['plain_text']

        return NotionPage(page_id, last_edited_time, url, title)
