使用 Bottle-Peewee-Plugin 连接到我的数据库的问题

Question

我制作了一个脚本 (dbcreation.py)，它使用 bottle-peewee-plugin:

创建一个数据库

import os, sys
from bottle import Bottle
from bottle_peewee import PeeweePlugin
from peewee import Model, ForeignKeyField, CharField, TextField, IntegerField, BooleanField, DateTimeField, DateField, TimeField
import datetime

app = Bottle()
db = PeeweePlugin('sqlite:///x.db')

class BaseModel(Model):
    class Meta:
        database = db.proxy

class Roomtype(BaseModel):
        roomtype_de = CharField(max_length=80)
        hint_de = CharField(max_length=250)

app.install(db)

db.database.create_tables([Roomtype])

roomtypes = [
    {'roomtype_de': 'bla'},
    {'roomtype_de': 'bla'},
]

with db.database.atomic():
    Roomtype.insert_many(roomtypes).execute()

还有另一个脚本 (app.py) 将包含我的 bootle-app：

from bottle import Bottle, route, get, post, request, run, template
from bottle_peewee import PeeweePlugin
from peewee import Model, ForeignKeyField, CharField, TextField, IntegerField, BooleanField, DateTimeField, DateField, TimeField    

app = Bottle()
db = PeeweePlugin('sqlite:///x.db')

@route('/my_function')
def my_function():
        return db.database.Roomtype.get(Roomtype.id == 1).roomtype_de

app.install(db)

我无法在我的数据库中选择任何条目并收到以下回溯：

return db.database.Roomtype.get(Roomtype.id == 1).roomtype_de
AttributeError: 'SqliteDatabase' object has no attribute 'Roomtype'

我错过了什么？

Answer 1

也许改成：

db.Roomtype.get(...)

我很困惑为什么你在某些地方使用db.Roomtype，而在其他地方只是简单的旧Roomtype。
