How can I read data from database and show it in a PyQt table












-2















I am trying to load data from database that I added to the database through this code PyQt integration with Sqlalchemy .I want the data from the database to be displayed into a table.I have tried this code.But,I am not getting it to load the data appropriately.I think the SqlAlchemy query may be wrong.
Any help will be appreciated.



I am getting this error:



File "/Users/tunji/Desktop/plain.py", line 75, in load

    result = session(Employee).query.all()



NameError: global name 'Employee


but when I updated this line of code:



from employee import Employee


I am now having this error:




Traceback (most recent call last): File "plain.py", line 82, in load
for column_number,data in enumerate(row_data): TypeError: 'Employee' object is not iterable

  • This line in the MainWindow.load() method: result = session(Employee).query.all(). The variable Employee is not defined anywhere in your module. Either you need to define the Employee model in you module, or import it from somewhere.
