How do I create a table in PyQt and populate it from a postgresql database?
I'm new to python and looking for some help:
I want to create a window and display a table in the window, populated from a postgresql table.
#!/usr/bin/python
import psycopg2
from psycopg2 import Error
import sys
from prettytable import PrettyTable
from PyQt6.QtWidgets import QApplication, QWidget
class Example(QWidget):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
try:
# Connect to an existing database
connection = psycopg2.connect(user="postgres",
password="mydb",
host="localhost",
port="5432",
database="mydb")
# Create a cursor to perform database operations
cursor = connection.cursor()
# Executing a SQL query
cursor.execute("SELECT * FROM table;")
# Fetch result
record = cursor.fetchall()
except (Exception, Error) as error:
print("Error while connecting to PostgreSQL", error)
finally:
if (connection):
cursor.close()
connection.close()
print("PostgreSQL connection is closed")
x=PrettyTable()
x.field_names = ["workorder_id", "part_id", "workorder_total"]
x.add_rows(record)
print(x)
self.setGeometry(300, 300, 300, 200)
self.setWindowTitle('Workorders')
self.show()
def main():
app = QApplication(sys.argv)
ex = Example()
sys.exit(app.exec())
if __name__ == "__main__":
main()
To clarify, I can use the psycog2 module to fetch information and print it to the console. However how do I go about actually creating a visual table, and populate the table from my record
array
python
postgresql
pyqt
pyqt6
