OperationalError: no such table: books on python anywhere
OperationalError: no such table: books on python anywhere
我在 python 上的任何地方都有一个文件结构：
flaskhost（文件夹），其中包含：
- app.py
- books.db
app.py 包含 -:
import flask
from flask import request, jsonify
import sqlite3
app = flask.Flask(__name__)
app.config["DEBUG"] = True
def dict_factory(cursor, row):
d = {}
for idx, col in enumerate(cursor.description):
d[col[0]] = row[idx]
return d
@app.route('/', methods=['GET'])
def home():
return '''<h1>Distant Reading Archive</h1>
<p>A prototype API for distant reading of science fiction novels.</p>'''
@app.route('/api/v1/resources/books/all', methods=['GET'])
def api_all():
conn = sqlite3.connect('books.db')
conn.row_factory = dict_factory
cur = conn.cursor()
all_books = cur.execute('SELECT * FROM books;').fetchall()
return jsonify(all_books)
@app.errorhandler(404)
def page_not_found(e):
return "<h1>404</h1><p>The resource could not be found.</p>", 404
@app.route('/api/v1/resources/books', methods=['GET'])

我正在尝试按照本教程进行操作

我的网站托管于：
但是当我通过
调用 api 时
http://127.0.0.1:5000/api/v1/resources/books?author=Connie+Willis
它告诉我错误：
sqlite3.OperationalError: no such table: books
如何解决此问题并在 pythonanywhere.com 上托管应用程序？
P.S 在我的本地机器上它工作得很好
在 Pythonanywhere 上，当指向模板或静态文件以外的内容时（存储在它们自己的适当目录中，可通过 flask 访问），您必须提供完整路径：
conn = sqlite3.connect('/home/your_username/flaskhost/books.db')
