Saving app data
-
Hi lovely people,
I've been working on a QML + python app & want to save some data as described in http://docs.ubports.com/en/latest/appdev/guides/writeable-dirs.html. However I get a PermissionError trying to access /home/phablet/.local/share/<myappname>. Is there an AppArmor policy I should add or is there something else I'm missing?
Thanks in advance, Bambi

Hi @bambi, welcome to the forums.
Are you using the provided functions to retrieve the directory names or are you using a hardcoded string?
-
@bambi
Have you check for the common mistake while using AppArmore ?
After any AppArmor modification you have to increase the version number in order to the changes to apply. -
@arubislander Thanks! I used a hardcoded string because im trying to access the folder from python. Maybe that's a bad idea? I'll try it from qml with the function (when i can, laptop broke last night) to see if that works and otherwise post code+error

@AppLee Yes, did that, thanks for the response!

@bambi The path would be
${HOME}/.local/share/${APP_PKG_NAME}so if your name isforest.bambifor example, it would end up as/home/phablet/.local/share/forest.bambias the directory path.You will also need to first create the directory before you can create any files inside it.

@dobey Thanks for the response! Turns out the mistake I made was changing the applicationName in MainView a while back, forgetting about it and copying that into the path instead of the name in manifest.json.in. They are the same now & can create the folder

@bambi I have been bitten by this before and it took me forever to figure out that it is my responsibility to maintain this id in multiple places. I wonder whether there is a way to remove this headache and have only one single place to specify it making it impossible to forget that other place. or if we cant have a single truth, maybe at least get something to warn app developers when they changed one but not the other....

@doniks A warning has already been added (recently I think)
