group by task.start or if task.start does not exist by task.file.filenameWithoutExtension

[Adriz1er]

@matr095 helped me make the next group by, but that doesn't do anything

var newdate = []; \
if (task.start == '') { \
newdate.push(new Date(task.file.filenameWithoutExtension)); \
} \
else if (task.file.filenameWithoutExtension == '') { \
	newdate.push(new Date(task.start)); \
} \
return newdate.toString();

That's very unlikely - it must do something, even if it writes out an error message.

Here are some things that you can try:

• Start by making a small part of the group that you want. Then try building the pieces up from there.
• Look in the Task Properties docs to see the type that each value has.
• For example, task.start == '' with never be true, as task.start has type TasksDate, not string.
• However, task.start.formatAsDate() == '' would match tasks with no start date

I don't know what new Date(task.file.filenameWithoutExtension) is trying to do... What does your file naming pattern look like? What is an example file name?

group by task.start or if task.start does not exist by task.file.filenameWithoutExtension

Looking at the parts of the description of this question, I would write it as:

group by function    \
    if (task.start.formatAsDate() !== '') return task.start.formatAsDate(); \
    return task.file.filenameWithoutExtension;

thank you I had never done javascript before trying to do certain requests with this plugin, I am making a vault model (that is free) to practice the GTD method if you are interested (even if it is in French I think that translating the name of the titles would be sufficient for use by someone who speaks English). I put an input: understand javascript query solution reported elements

I'm glad it worked.

I am hoping one day to have enough free time to make some of the javascript-based Tasks facilities available in built-in commands - it will be a lot of work, but worthwhile.

Good luck with your model.
