QSortFilterProxyModel by column value
1
Example of table model data
I have a gui with a tabWidget and inside each I have a tableview. Each tab describes a folder (see column type) with subdirs from which I pull the data. I want to have one main model that drives all views by attaching a QSortFilterProxy Model inbetween each tableview that filters the main model for the "type" of each individual TableView (passed into the subclass RenderTypeProxyModel). Bonus: Ideally, they should be sorted as well, so that the most recent view (see date column) comes out on top.
Here is my current version but the table remains blank for a reason I can't figure out:
import sys
import os
from datetime import datetime
from pprint import pprint
from PySide2 import QtCore, QtGui, QtWidgets
#To be replaced by env variable
pathToProject = "/run/media/centos7/Data/Projects/Programming/Pipeline/SampleProject"
allowedExportTypes = ["img-prv", "img-final", "img-cg", "img-src", "camera"]
class ExportTableModel(QtCore.QAbstractTableModel):
def __init__(self, exportData, horizontalHeaders, parent=None):
QtCore.QAbstractTableModel.__init__(self, parent)
self.__exportData = exportData
self.__horizontalHeaders = horizontalHeaders
def rowCount(self, parent):
return len(self.__exportData)
def columnCount(self, parent):
return len(self.__horizontalHeaders)
def data(self, index, role): #Returns the data stored under the given role for the item referred to by the index.
if role == QtCore.Qt.DisplayRole:
row = index.row()
column = index.column()
value = self.__exportData[row][column]
return value
def headerData(self, section, orientation, role):
if role == QtCore.Qt.DisplayRole:
if orientation == QtCore.Qt.Horizontal:
if section < len(self.__horizontalHeaders):
return self.__horizontalHeaders[section]
else:
return "not implemented"
def tableSetup(tableView):
tableView.setAlternatingRowColors(True)
tableView.setSelectionBehavior(QtWidgets.QTableView.SelectRows)
tableView.setSortingEnabled(True)
class RenderTypeProxyModel (QtCore.QSortFilterProxyModel): #Custom Proxy Model
def __init__(self, type, parent=None):
super(RenderTypeProxyModel,self).__init__(parent)
self.__type = type
def filterAcceptsRow(self, row, parent): #returns true if the given row should be included in the model
model = self.sourceModel()
index = model.index(row, 3, parent)
if model.data(index,QtCore.Qt.DisplayRole) == type:
return True
else:
return False
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
horizontalHeaders = ["status", "comment", "task", "type", "version", "user", "date", "filepath"] #horizontal header data
#exportData = #insert sample data list of lists here for testing

The error is caused because type is a reserved word in python:
if model.data(index,QtCore.Qt.DisplayRole) == type:
you must use self.__type.
On the other hand if you want to sort the data by date it is not necessary to enable setSortingEnabled(), just use sort().
from PySide2 import QtCore, QtGui, QtWidgets
#To be replaced by env variable
allowedExportTypes = ["img-prv", "img-final", "img-cg", "img-src", "camera"]
class ExportTableModel(QtCore.QAbstractTableModel):
def __init__(self, exportData, horizontalHeaders, parent=None):
super(ExportTableModel, self).__init__(parent)
self.__exportData = exportData
self.__horizontalHeaders = horizontalHeaders
def rowCount(self, parent=QtCore.QModelIndex()):
return len(self.__exportData)
def columnCount(self, parent=QtCore.QModelIndex()):
return len(self.__horizontalHeaders)
def data(self, index, role=QtCore.Qt.DisplayRole):
if role == QtCore.Qt.DisplayRole:
row = index.row()
column = index.column()
value = self.__exportData[row][column]
return value
def headerData(self, section, orientation, role=QtCore.Qt.DisplayRole):
if role == QtCore.Qt.DisplayRole and orientation == QtCore.Qt.Horizontal:
if section < self.columnCount():
return self.__horizontalHeaders[section]
return "not implemented"

self.__type = _type
def filterAcceptsRow(self, row, parent):
_type = self.sourceModel().index(row, 3, parent).data()
return _type == self.__type
def lessThan(self, left, right):

left_data = self.sourceModel().data(left)
right_data = self.sourceModel().data(right)

for _type in allowedExportTypes:

Yes, you're correct. I read the code at least 10 times and it never spotted the type error. Sometimes it just needs another pair of eyes. Could you go a bit more into detail about sorting? Is this done inside the proxy model or in the tableview widget and how would you implement it? Thanks you so far :)

Nov 15 '18 at 18:27
@jnt Have you tried my solution ?, already implemented the filter and the order, now I'm working on simplifying more things in your code.

I have been searching through the qt documentation but haven't been able to find the sort() method. I'm highly interested in the improvements to my code as well, as I am probably able to learn something from that. Thank you! Edit: Ah, just discovered sort () inside the QSortFilterProxy model doc.

Ok, I marked it as correct answer. Still I am eager to learn about the improvements mentioned in your earlier answer. Have a great day :)

The error is caused because type is a reserved word in python:
if model.data(index,QtCore.Qt.DisplayRole) == type:
you must use self.__type.
On the other hand if you want to sort the data by date it is not necessary to enable setSortingEnabled(), just use sort().
