PyQt Selected row in Table Widget

[rarevesselt]

   
How can I dynamically select row and get the product id value for the selected product to be passed into the query?

def deleteProduct(self):
        row = self.products_table.currentRow()
        if row > -1:
           product_id = (self.products_table.item(row, 0).text(), )
           query = session.query(Product).filter(Product.product_id=='product_id').first()
           session.delete(query)
           session.commit()
            #self.dbCursor.execute("""DELETE FROM Main WHERE username=?""", currentUsername)
            #self.dbConn.commit()
           self.products_table.removeRow(row)

Am getting this error :

    reraise(type(exception), exception, tb=exc_tb, cause=cause)
  File "/usr/local/lib/python2.7/site-packages/sqlalchemy/engine/base.py", line 1193, in _execute_context

    cursor.execute(statement, parameters)
sqlalchemy.exc.InterfaceError: <exception str() failed>

How can I resolve this error?

what is

if row > -1:

and the comma in

(self.products_table.item(row, 0).text(), )

i would check if there is a selection and remove the comma

def deleteProduct(self):
        if self.products_table.selectionModel().hasSelection():
           row = self.products_table.currentRow()
           product_id = (self.products_table.item(row, 0).text())
           query = session.query(Product).filter(Product.product_id=='product_id').first()
           session.delete(query)
           session.commit()
            #self.dbCursor.execute("""DELETE FROM Main WHERE username=?""", currentUsername)
            #self.dbConn.commit()
           self.products_table.removeRow(row)

Thanks for your response.This is the working code.Thanks Axel_Erfurt.I removed the comma too.

The row>-1 too does not do anything.

def deleteProduct(self):
        row = self.products_table.currentRow()
        currentproductid = (self.products_table.item(row, 0).text() )
        query = session.query(Product).filter(Product.product_id==str(currentproductid)).first()
        session.delete(query)
        session.commit()
        self.products_table.removeRow(row)
