Unresolved attribute reference 'setModel' for class 'Dialog'

Question

Trying to create a dialog class which will contain a QTableView widget, all is good, information gets inserted, but i cannot understand why pycharm show the error: "Unresolved attribute reference 'setModel' for class 'Dialog'"

all class code here:

from PyQt5.QtGui import QStandardItemModel, QStandardItem
from PyQt5.QtWidgets import QDialog, QTableView
from PyQt5.uic import loadUi


class Dialog(QDialog):
    def __init__(self):
        super(Dialog, self).__init__()
        loadUi("dialog.ui", self)
        self.table = self.findChild(QTableView, "tableView")

    def fill_table(self, data):
        column_names = ["full_name", "mail", "age", "phone_number"]
        model = QStandardItemModel(1, 4)
        model.setHorizontalHeaderLabels(column_names)

        for col_idx in range(4):
            item = QStandardItem(data[col_idx])
            model.setItem(0, col_idx, item)

        self.table.setModel(model)

explain me what's going on and suggest solutions to the problem.

You can use type hints to make sure that pycharm knows the type of dynamically created objects:

class Dialog(QDialog):
    def __init__(self):
        super(Dialog, self).__init__()
        loadUi("dialog.ui", self)
        self.table: QTableView = self.findChild(QTableView, "tableView")

or without the unecessary findChild

class Dialog(QDialog):
    def __init__(self):
        super(Dialog, self).__init__()
        loadUi("dialog.ui", self)
        self.tableView: QTableView
