37. simple memo plugin with PeeWee
make data modeles, as models.py like below.
import os
from peewee import SqliteDatabase, Model, CharField, TextField
db = SqliteDatabase(os.path.join(os.path.dirname(__file__), 'bot_database.db'))
class Memo(Model):
name = CharField(primary_key=True)
text = TextField()
class Meta:
database = db
db.connect()
db.create_tables([Memo], safe=True)

def memo_save(message, name, text):
memo, created = Memo.get_or_create(name=name, text=text)
memo.save()
message.reply(f'I remembered a memo "{name}"')
@respond_to(r'memos+shows+(S+)')
def memo_show(message, name):
memo = Memo.get_or_none(name=name)
if memo:
message.reply(f'memo "{name}" is belown```n{memo.text}n```n')
else:
message.reply(f'memo "{name}" ... hmm ..., I don't know ¯_(ツ)_/¯')
