Retrieve data when clicking a button - class

Question

Trying to receive input from WCT_Control into WCT_DataPull
Cant figure out how to get the data into WCT_DataPull to perform an action with it. I think I am going about this backwards, but I also think I have been staring at it too long.
Essentially, the user enters the information necessary into a GUI to connect to a specific SQL table (predetermined) and then saves the data in the table and outputs it as a csv file backup.
I want the user to click the submit button and that creates the backup. However, at this point when I click the button, it will store all the data in the variables (If I put a print statement in I see the correct values), but I cant seem to figure out how to get the variables to WCT_DataPull, where the backup creation action is performed.
WCT_Control
from PyQt5.QtWidgets import *
from WCT_View import Ui_MainWindow
class Controller(QMainWindow, Ui_MainWindow):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.setupUi(self)
self.run.clicked.connect(lambda : self.submit())
def submit(self):
self.run.clicked.connect()
server = self.server_entry.text()
database = self.data_entry.text()
station = self.station_entry.text()
app = self.app_entry.text()
backup_name = self.filename_entry.text()
self.server_entry.setText('')
self.data_entry.setText('')
self.station_entry.setText('')
self.app_entry.setText('')
self.filename_entry.setText('')
return server, database, station, app, backup_name
WCT_DataPull
from WCT_Control import *
import pyodbc
import csv
pull_data = Controller()
def write_bak():
driver = 'ODBC Driver 17 for SQL Server'
serv, data, stat, app, bak_name = pull_data.submit()
conn = pyodbc.connect('DRIVER={0};SERVER={1};DATABASE={2};Trusted_Connection=yes'.format(driver, serv, data))
cursor = conn.cursor()
rows = cursor.execute("""
select DnsName, PackageName, Code, Value from WorkstationApplicationSettings
where DnsName=? and PackageName=?
""", stat, app).fetchall()
for row in rows:
print(row.PackageName,':', row.Code, ':', row.Value)
with open(bak_name, 'w', newline='') as f:
writer = csv.writer(f)
writer.writerows(rows)

Answer 1

So you just have to do the things in opposite way, instead of using PYQT5 in WCT script, use the WCT function in PYQT5 script
WCT_Control
from PyQt5.QtWidgets import *
from WCT_DataPull import write_bak
class Controller(QMainWindow, Ui_MainWindow):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.setupUi(self)
self.run.clicked.connect(lambda : self.submit())
def submit(self):
self.run.clicked.connect()
server = self.server_entry.text()
database = self.data_entry.text()
station = self.station_entry.text()
app = self.app_entry.text()
backup_name = self.filename_entry.text()
self.server_entry.setText('')
self.data_entry.setText('')
self.station_entry.setText('')
self.app_entry.setText('')
self.filename_entry.setText('')
write_bak(serv, data, stat, app, bak_name)
WCT_DataPull
import pyodbc
import csv
def write_bak(serv, data, stat, app, bak_name):
driver = 'ODBC Driver 17 for SQL Server'
conn = pyodbc.connect('DRIVER={0};SERVER={1};DATABASE={2};Trusted_Connection=yes'.format(driver, serv, data))
cursor = conn.cursor()
rows = cursor.execute("""
select DnsName, PackageName, Code, Value from WorkstationApplicationSettings
where DnsName=? and PackageName=?
""", stat, app).fetchall()
for row in rows:
print(row.PackageName,':', row.Code, ':', row.Value)
with open(bak_name, 'w', newline='') as f:
writer = csv.writer(f)
writer.writerows(rows)
Also Make sure to write the code to run the WCT_control by using Qapplication
