I'm trying to get a PyQt lineEdit widget to place its' contents within a variable in the module 'followup' but for some reason the module does not recognize the PyQt MainWindow as being properly instantiated.
#workbot_main.py
import gspread
import os
import sys
sys.path.append(os.path.abspath(r"C:\Users\leamy\Desktop\work bot\workbot.py"))
sys.path.append(os.path.abspath(r"C:\Users\leamy\Desktop\work bot\initial.py"))
sys.path.append(os.path.abspath(r"C:\Users\leamy\Desktop\work bot\followup.py"))

#workbot.py is the QTdesigner file containing the widgets,

super().__init__(*args, **kwargs)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
followup_start_button = self.ui.followup_start_button
followup_start_button.clicked.connect(threads.begin_initialize)
def followup_starting_number(self):
num = self.ui.lineEdit.text()
return num

widget.show()
app.exec_()
#followup.py
import workbot_main
def initialize():
row_number.number = workbot_main.MainWindow.followup_starting_number()
print(row_number.number)
I get this error

I can't understand why it doesn't work.
Edit:
If I try to use
row_number.number = workbot_main.widget.followup_starting_number()
instead of
row_number.number = workbot_main.MainWindow.followup_starting_number()
I get this error

I don't know if that is related.
I'm current encountering an issue where I'm using threads to perform tasks in the background upon a POST request, but I'm having an issue with using an integer as a parameter; or any data type as a parameter for that matter.
What is supposed to happen is that it's supposed to perform everything inside of the POST request check, then perform something else after that has been completed.
Imports:
from flask import Flask, url_for, render_template, redirect, request
from flask.cli import with_appcontext, click
import sqlalchemy
from flask_sqlalchemy import SQLAlchemy

class Compute(Thread):
def __init__(self, secs):
Thread.__init__(self)
self.secs = secs
def run(self):
print('Thread Opened')
sleep(self.secs)
db.session.query(Users).filter(Users.username == current_user.username).first().requests += 1
db.session.commit()
print('Thread Closed')
Flask Route:
#app.route('/index', methods=['GET', 'POST'])

def index():
if request.method == 'POST':
time = '5'
thread = Compute(int(time))
thread.start()
return redirect(url_for('index'))
else:
return render_template('index.html')
The error I am receiving when the thread tries to start is this:

I am not very experienced with threading, I've only dabbled with it in other projects so I'm not sure why I'm getting this error; any help is greatly appreciated.
You need to remove the #click.command and #click.pass_context decorators.
#click.command(name='run')
#click.pass_context
class Compute(Thread):
Those decorators are wrapping the class in a function that takes its own parameters. It is intended for running a function from the command line and parsing arguments. This is why the traceback shows args = list(args) as the line causing the error.
https://github.com/pallets/click/blob/master/src/click/core.py#L916-L917
:param args: the arguments that should be used for parsing. If not
provided, ``sys.argv[1:]`` is used.
I'm converting a Google App Engine Python 2 project to Python 3
My understanding from reading the documentation I understand the preferred path is to run the main python program directly, skipping dev_appserver.py as was done in the past.

Is there additional logic that should be included after migration to start/initialize the datastore?
Thanks,

The API for NDB library in Python3 has changed significantly. For developing on localhost you have to:
run DataStore Emulator, since you're not running dev_appserver anymore:
$ gcloud beta emulators datastore start
if you use the new NDB Library, then each NDB operation needs to be wrapped in a context manager:
with ndb_client.context(): # <- you need this line
cls.get_or_insert('master')
edit: instead of wrapping each NDB call with a context manager, you can use a middleware which will wrap the whole request cycle into the NDB context:
class NDBMiddleware:
def __init__(self, app):
self.app = app
self.client = ndb_client
def __call__(self, environ, start_response):
with self.client.context():
return self.app(environ, start_response)
app = Flask(__name__)
app.wsgi_app = NDBMiddleware(app.wsgi_app)
I am using flask to create a webform on http://localhost:5000/ and my goal is for the form to prompt the user for two inputs, then write those inputs into two new python3 files named test2.py and test3.py. The variable 'text' and 'text1' keep coming up as undefined. Here is the code and its error:
code:
from flask import Flask, request, render_template
app = Flask(__name__)
#app.route('/')
def my_form():
return render_template('my-form.html')
#app.route('/', methods=['POST'])
def my_form_post():
text = request.form['text']
text1 = request.form['text1']
with open('test2.py', 'w+') as file:
file.write(text)
with open('test3.py', 'w+') as file:
file.write(text1)
error:
Traceback (most recent call last):
File "test1.py", line 15, in <module>
file.write(text)
NameError: name 'text' is not defined
Thanks!
That is because text and text1 are defined in the function, while file handling is outside. The file handling should be inside the post method.
