I have the same version as you, but in Qt5.1 (with which I compiled it) some of the now deprecated API QDjango uses are removed by default. I don't know in which version of Qt this started. I had to insert something like
@
DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x040800
@
somewhere in qdjango.pri to compile it properly. -

Me too, but that didn't stops me to use it because it suppose to work for Qt4 and Qt5.

I have just looked into the test suite bundled with QDjango and there are cases for one-to-many and many-to-many relationships. So, apparently, there is support of such relationships. I will give it a spin to see how convenient it is compared to pure Qt.

It appears that there is no relationship support in QDjango, after all. You can only emulate relationships with query sets on foreign keys. Further on, to create a many-to-many relationship between two entities, one must create a third one (equivalent to a separate foreign key table) and then filter query sets based upon that third entity. That's all very much doable, but basically amounts to hand-coding all of relationship management.
QxOrm does provide relationship support, so it may be more convenient to use if you need to maintain many relationships and/or fiddle with them a lot. I think I am still going to try QDjango first and fall back on QxOrm if it does not work out.
Please, let me know of your experience with QDjango. I will post my impressions after I play with it.

Hi,
I'm the developer of QxOrm library.
FYI, we have released QxEntityEditor to make easier to work with QxOrm library : now, you can design your data model in few minutes and generate quickly a Qt/C++ project (and the SQL database associated).

After years of this post, Qt still without a practical open source ORM :(
The only reliable option is QxOrm which is useless without QxEntityEditor because it's complicated without it but QxEntityEditor is commercial product so I'm still using the old way with Qt.
Cheers

I have found Nut https://marketplace.qt.io/collections/all-products/products/nut resp. https://github.com/HamedMasafi/Nut which results actively maintained.
Not sure if the one mentioned in the previous post (CuteEntityManager, https://github.com/Professi/cuteentitymanager) is still alive...

Hi there,
2022 here... still no integrated ORM in Qt?
