[CAP] Select exists
So far I have not found a better/shorter way to check if a table entry exists than the following:
let exists = await SELECT(1).from(Books,201)
return (exists .length > 0) ? true : false

[JavaScript] Labeled statement
A labeled statement can be used to exit a nested loop.
function loop () {
dance: for (let i = 0; i < 4; i++) {
for (let j = 0; j < 4; j++) {
if (j === 2) break dance
}
}
}

[SAPUI5] Add custom header parameter to all oData queries
Simply go to your Component.js file and add this line to the init function:
this.getModel().setHeaders({"myCustomParameter": "test"})
In a CAP Backend, you get this parameter from the express req object, which can be accessed via the req.http property:
req.http.req.headers['myCustomParameter']
And here is a nice code snippet, on how to read this header parameter in an ABAP system: https://answers.sap.com/answers/425621/view.html
[SAPUI5] Suppress default oData error message / display meaningful error messages
Create a separate ErrorHandler.js file, like it is described here and either do your own error handler implementation, or take the sample from here. To avoid displaying multiple errors at once, follow this chapter.
Thanks to the provided dsag sample, this is takes only a few minutes and improves the user experience a lot!
[Linux Mint] Transmission Remote GUI: download directory path is not absolute
Every few months, I run into this issue when adding a torrent to transgui:
Although there is a 5-year-old closed issue on this bug, which also led to a code adjustment, this bug still seems to exist: https://github.com/transmission-remote-gui/transgui/issues/1270
The user Kethsar has probably already found the right cause and gives some hints on how to solve it. At least it helped me to find a workaround:
- close transgui if it’s running, otherwise your changes will get overwritten again
- nano ~/.config/Transmission\ Remote\ GUI/transgui.ini
- search for the
[AddTorrent.transmission]section - remove some entries which a related, e.g.
Folder1=/my/path/1
FolHit1=1
FolExt1=
LastDt1=18.02.2024
Folder2=/my/path/2
FolHit2=3
FolExt2=
LastDt2=18.02.2024
...
- save & quit nano
- start trangui again and try to add a torrent again
It seems like the issues occurs, when the [AddTorrent.transmission] section reaches Folder50.
[Home Assistant] Mushroom Template card – Badge Icon
Somehow, I’ve only just realized that a badge icon can be used to display another entity status on a template card, even though it’s written in the documentation. I now use it to display the status of presence or motion sensors in the respective rooms.
badge_icon: >-
{{ "mdi:motion-sensor" if states("binary_sensor.0xb4e3f9fffeb689d4_occupancy") == "on" }}
badge_color: >-
{{ "green" if states("binary_sensor.0xb4e3f9fffeb689d4_occupancy") == "on" }}
[ABAP] xsdbool
Somehow I always forget that there is a boolean function in ABAP. That’s why I’m writing this post to hopefully remember it better. 🙂
If you just want to check something for truthiness, you can do it in the following three ways:
IF sy-subrc = 0.
result = abap_true.
ELSE.
result = abap_false.
ENDIF.
result = SWITCH #( sy-subrc WHEN 0 THEN abap_true
ELSE abap_false ).
result = xsdbool( sy-subrc = 0 )
