Python Forum

Greetings,
I am developing a Flask application, but keep getting an error from:
import theapp
and
from theapp import app??

This is the folder structure:
I have a folder called theapp, with _init_, db and routes.py

Appreciate any pointers where I am going wrong??
Thanks,
Clive

In run.py the code is:

from flask import Flask
from theapp import app
#import theapp.routes
app = Flask(__name__)

if __name__ == "__main__":
    app.run(debug=True)

In routes.py

import flask
from flask import Flask
from flask import render_template, request, redirect, send_file,url_for, flash
from theapp import app
#import app
#from theapp.db import conn, text, exc#from theapp.helper import getcriteria, getyear, create_financial_year, getquarter, updatefield, getresults, deleterecord, log, get_isodate,
#from theapp.helper import *
#from theapp.forms import *
#from theapp.models import User
#from theapp.loginsystem import *
#from theapp.view_programme import *
import csv
import os
import datetime as dt
import urllib.request
import logging
import datetime
import hashlib
import random
import json

@app.route('/')
@app.route('/index')
def index():
    return "Hello, World!"

It sounds like theapp is in a location that is not being searched.
This is a useful guide to checking the path:

Thanks for you msg,

Ok, from your post I presume that I need to load theapp module in the site-packages??

If the code is not compiled, how do I save it to the site-packages??

Regards,

Clive

If you are installing modules using pip, then they will be automatically put in the site-packages folder.
If theapp is your own module, then it needs to be located in one of the searched locations so that python can find it.
Does your __init__.py include a line like "from .theapp import *"? You'll need that.

Hi topfox,
Thanks for the message.

I added the import to __init__.py

Get an error message for .theapp
Does that mean that I have to copy the theapp folder to site packages???
Thought I would copy a compiled theapp.py to site packages.

Thanks
Clive

from flask import Flask
app = Flask(__name__)
app.config.from_object('config')
app.jinja_env.add_extension('jinja2.ext.do')
from .theapp import *

The error msg:

Error:
Traceback (most recent call last):
  File "C:/Users/tmpgcesn/PycharmProjects/Flask/FlaskTest/theapp/__init__.py", line 5, in <module>
    from .theapp import *
ImportError: attempted relative import with no known parent package

Process finished with exit code 1

Really weird

I had to use import Flasktest.theapp, that works.

In the past I just used theapp, not FlaskTest.theapp??

Now I am getting an new error..
All the modules are installed??

Error:
- missing __init__.py in a package;
- package or module path not included in sys.path;
- duplicated package or module name taking precedence in sys.path;
- missing module, class, function or variable;

Debugged import:

- 'config' not found.

Original exception:

ModuleNotFoundError: No module named 'config'

Process finished with exit code 1

It seems that the error points to the werkzeug module??
Weird??

PYTHONPATH = C:\Users\tmpgcesn\AppData\Local\Programs\Python\Python38

Error:
Traceback (most recent call last):
  File "C:\Users\tmpgcesn\AppData\Local\Programs\Python\Python38\lib\site-packages\werkzeug\utils.py", line 865, in import_string
    __import__(import_name)
ModuleNotFoundError: No module named 'config'

In a previous Flask app, I imported theapp and it worked..

In this app I had to use:

from flask import Flask
app = Flask(__name__)
app.config.from_object('config')
app.jinja_env.add_extension('jinja2.ext.do')
import FlaskTest

PYTHONPATH=C:\Users\tmpgcesn\AppData\Local\Programs\Python\Python38
When I run sys.path I get:

C:\Users\tmpgcesn\PycharmProjects\Flask\FlaskTest\theapp
C:\Users\tmpgcesn\PycharmProjects\Flask
C:\Users\tmpgcesn\AppData\Local\Programs\Python\Python38\python38.zip

C:\Users\tmpgcesn\AppData\Local\Programs\Python\Python38\lib\site-packages\Pythonwin

I am getting an error msg from __init__.py??

Error:
- missing __init__.py in a package;
- package or module path not included in sys.path;
- duplicated package or module name taking precedence in sys.path;
- missing module, class, function or variable;

Debugged import:

- 'config' not found.

Original exception:

ModuleNotFoundError: No module named 'config'

I opened the project in Visual Code, it ran without any errors.
Appears that PyCharm Community version is the problem, not the code??
Weird!!
