当前,我正在尝试在PythonAnywhere上部署我的第一个FLASK应用程序。
我不确定这是否是正确的术语,但是我有一个文件夹作为模块,因此我似乎找不到正确的方法来部署应用程序。我什至不知道从哪里开始解决这个问题。有什么建议吗?
File and Folder Layout Snipped
我的 init .py代码是:
import os
from flask import Flask
def create_app(test_config=None):
# create and configure the app
app = Flask(__name__, instance_relative_config=True)
app.config.from_mapping(
SECRET_KEY='secret',
DATABASE=os.path.join(app.instance_path, 'LAMA.sqlite'),
)
if test_config is None:
# load the instance config, if it exists, when not testing
app.config.from_pyfile('config.py', silent=True)
else:
# load the test config if passed in
app.config.from_mapping(test_config)
# ensure the instance folder exists
try:
os.makedirs(app.instance_path)
except OSError:
pass
# database
from . import db
db.init_app(app)
# authentication blueprint
from . import auth
app.register_blueprint(auth.bp)
# blog blueprint - the main index
# from . import blog
# app.register_blueprint(blog.bp)
# app.add_url_rule('/', endpoint='index')
# book blueprint
from . import book
app.register_blueprint(book.bp)
app.add_url_rule('/', endpoint='index')
return app
我还遵循了python调试页面,在其中执行以下操作:
>>> import LAMA
>>> print(LAMA)
<module 'LAMA' from '/home/ivanv257/LAMA_MAIN/LAMA/__init__.py'>
因此在此阶段,我的WSGI配置文件中包含:
import sys
path = '/home/ivanv257/LAMA_MAIN/LAMA/__init__.py'
if path not in sys.path:
sys.path.append(path)
from LAMA import app as application
我还尝试了许多其他组合,例如
path = '/home/ivanv257/LAMA_MAIN/LAMA/'
from init import app as application
path = '/home/ivanv257/LAMA_MAIN/'
from init import app as application
path = '/home/ivanv257/LAMA_MAIN/'
from LAMA import app as application
我的源代码路径是:/ home / ivanv257 / LAMA_MAIN / LAMA,尽管我也尝试过其他组合,例如/ home / ivanv257 / LAMA_MAIN /
错误详情:
2018-12-08 10:05:32,028: Error running WSGI application
2018-12-08 10:05:32,030: ModuleNotFoundError: No module named 'LAMA'
2018-12-08 10:05:32,030: File "/var/www/ivanv257_pythonanywhere_com_wsgi.py", line 83, in <module>
2018-12-08 10:05:32,030: from LAMA import app as application # noqa

为解决我的问题,我在喇嘛导入create_app中更改了以下内容(有一些帮助):
import sys
path = '/home/ivanv257/LAMA_MAIN/LAMA'
if path not in sys.path:
sys.path.append(path)
from lama import create_app
application = create_app()
我还必须从中删除。只是进口
import db
db.init_app(app)
# authentication blueprint
import auth
app.register_blueprint(auth.bp)

您很近。要部署您的应用程序,请导航到用户仪表板上的webapps页面。如果尚未这样做,请单击“添加新的Web应用程序”按钮,然后输入所需的应用程序名称。然后,在仪表板上的同一webapp页面上,向下滚动到页面的“代码”部分。单击“源代码” a href
,然后将绝对路径(完整路径)添加到存储lama_main
文件的init.py
目录中。
接下来,单击“ WSGI配置文件”链接。在您应用程序的WSGI配置文件中,将正确的路径设置为父目录,然后从app
文件中导入init.py
:
import sys
# add your project directory to the sys.path
project_home = u'/home/your_user_name/lama_main'
if project_home not in sys.path:
sys.path = [project_home] + sys.path
# import flask app but need to call it "application" for WSGI to work
from init import app as application #note that the module being imported from must be the file with "app" defined.
然后,保存WSGI文件并返回到仪表板上的webapp面板。点击“重新加载{您的网站名称}”按钮。现在,您应该可以通过单击页面顶部的主链接来访问该站点。
