I can't get even the simpliest application to work with Sailfish and PyOtherSide. What i'm doing wrong? Is it with addImportPath? Here is the code:

pressbutton.qml

import QtQuick 2.0
import Sailfish.Silica 1.0
import io.thp.pyotherside 1.0

ApplicationWindow
{
    initialPage: Page {
        id: page

        Button {
            id: mybtn
            text: "press"
            anchors.centerIn: page
            onClicked: {
                py.call('pressbutton.pressme', function() {});
            }
        }

        Python {
            id: py
            Component.onCompleted: {
                addImportPath(Qt.resolvedUrl('/usr/share/pressbutton/qml'));
                importModule('pressbutton', function() {});
            }
        }
    }

    cover: Qt.resolvedUrl("cover/CoverPage.qml")
}

and pressbutton.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import pyotherside

def pressme():
    f = open("/home/nemo/Documents/file.txt","a")
    f.write("this is example text")
    f.close()

What does the QtCreator / SDK say when you try to build / deploy that?

I deploy that with "mb2 -t SailfishOS-armv7hl rpm" and it doesn't give any error. The App works (there's button in the middle of screen) but when pressed it doesn't create new file to the Documents-folder.

You should improve your example code with onError callback and return a value from your pythons module method that can be printed out with console() QML function. Do also remember that you call your python code async. For a synchronous test use call_sync(). HTH.

Looking at your code:

py.call('pressbutton.pressme', function() {});

Here, you are missing the args parameter of the call, it should be:

py.call('pressbutton.pressme', [], function(result) {});

(note the addition of [] - an empty argument list - there)

Additionally, if you don't have PyOtherSide 1.1 (e.g. from Nemo Mobile "devel" repositories), you have to strip the leading 'file://' from the Qt.resolvedUrl() result for now (PyOtherSide 1.1 and later will strip it for you automatically, but 1.1 is not yet in the Sailfish OS release repositories, it should be with one of the next updates), if the import path should be relative to the QML file:

addImportPath(Qt.resolvedUrl('.').substr('file://'.length));

If you are just adding an absolute, hardcoded path, you can just use that, without Qt.resolvedUrl():

addImportPath('/usr/share/pressbutton/qml');

That should make your example work.

By the way, the Python function can be rewritten as:

def pressme():
    with open("/home/nemo/Documents/file.txt","a") as f:
        f.write("this is example text")

See this article for how "with" is used there. If you want to write line-wise to that file, use f.write('this is example text\n') or even print with the file= keyword argument, like:

def pressme():
    with open("/home/nemo/Documents/file.txt","a") as f:
        print("this is example text", file=f)

Let me know if that works for you and if you have any other questions :)

Now it works! thanks! That is a great job you do with PyOtherSide.
