DataviewJS Snippet Showcase

Hi, does somebody have some example on how to get all Values from a Specific Key from all notes with a specific tag?
Plus the values should be stored in an array with value, value (as I need it for templater suggester).

scholarInTraining · August 26, 2022, 5:01pm

Possibly useful: you can use Dataview DQL queries inside dataviewjs if it is easier to express a query that way. e.g. dv.tryQuery('LIST WITHOUT ID SpecificKey FROM #tag').values should give you a list of the values you want, but there will be duplicates so you probably want to convert the result to a Javascript Set before mapping to the [value, value] array format that you want.

mbreiden · August 26, 2022, 5:33pm

I’m not getting there (lack of JS knowledge)

let pages = dv.pages("#content/code")
let allPrograms = pages.map(a => a.program);
let uniqPrograms = allPrograms.filter((item, index) => allPrograms.indexOf(item) === index)

creates a Proxy { values: Array(5)… in console, what I need is {key: value, key: value… in console. If I replace a.program with [a.program, a.program] I get arrays in arrays…

btw: 5 is correct… it is normally 6 but one duplicate.

So I have the following problems:
a) how to get the correct datastructure
b) how to remove duplicates from that
c) how to remove undefined from that

Can anyone advise if its possible to populate a TaskList nested within a Table row? I’m trying to incorporate this, but when I attempt this, I’m left with fields within the actual table rows, and the TaskList rendered above the table.

Sample Markdown (codeblock tildes replaced with apostrophes):

'''dataviewjs
let md = dv.current().file.tasks
dv.table([" "], 
	md.map(m => [dv.taskList([m])])
	)
'''

- [ ] this task
- [ ] that task

i want to construct a dataviewjs table to show only the events coming in say september. i also have tags. Can someone help in the dataview query. i tried but was not able to construct based on september month

I also tried to do this via reactjs components but failed to get the data inside a md file. Hence now trying this via dataviewjs

below are my contents in md file:

Autumn starting | 2022-09-03 #event
Winter starting | 2022-11-03 #event
Birthday | 2022-12-03 #birthday
one more | 2022-10-23 #anniversary

You can have a look at my upcoming event calendar here, it should give you some pointers.

It creates a visual calendar view of all upcoming events:

I’m trying to build the DataviewJS query. That is extracting the vault path and building the full path for image by combining YAML Header where I have only name of the image with extension as string

YAML Header

name: Original
number: 1
image: "image12.jpg"
sphere: Earth

DataviewJS query

dataviewjs

//@ts-ignore

let adapter = app.vault.adapter;

 // VAULT PATH
const vault = adapter.getBasePath();

 // PATH WHERE I HAVE IMAGES
const vault_images = vault + "/Resources/Images/"

const pages = 
		dv.pages()
		.where(b => b.file.frontmatter.sphere === 'Earth')
		.sort(b => b.file.frontmatter.number)
		.array()
	.map(({file}) => {

 // PROBLEMATIC LINE
	return ["![](" + vault_images + file.frontmatter.image + ")",file.name, file.frontmatter.number]
})

dv.table(["Image", "Name", "Number"], pages)

Result

It gives me the table of all items, but there is just one image propery for all records. It looks like it is giving me all images as object.

I will really appreciate somebody who can help me to adjust the code

I am using $=dv.pages().length in a vault info bar to show the total number of files in the vault but I want to also have a inline snipped that shows the number of files modified today, what code would I use?

justdoitcc · September 28, 2022, 2:24am

You could use the following Inline DataviewJS Query.


### inDVJS10
QTY_modified_today=`$=dv
    .pages()
    .where((page) => page.file.mday.toFormat("yyyy-MM-dd") === dv.func.date("today").toFormat("yyyy-MM-dd")).length;`

Topic

Summary

How to filter the data by the filename of a link from the Markdown files with the case_YAML_Y-YYY structure?

Structures: case_YAML_Y-YYY

Summary

TIP:
1.AoH in the topic means an Array of Hashes.
2.Hashes in the topic means JavaScript Objects.

Definitions:

Structure Code: case_YAML_Y-YYY
Definitions: Use nested YAML fields, where a single root YAML field which is an Array of Hashes consists of
at least one Hash, which is represented by sub YAML fields “-YYY”.

YAML: Use YAML.
Y: a single root YAML field which is an Array of Hashes
-YYY: at least one Hash, which is represented by sub YAML fields “-YYY”

The first sub YYY, an element of the root Y, consists of multiple key/value pairs, as known as a Hash.
The second sub YYY, an element of the root Y, consists of multiple key/value pairs, as known as a Hash.

Data Structure: an AoH
Original Structure Code expressed in regular expressions: case_YAML_Y(-YYY){1,}

Basic Example: The AoH `drinks` consists of two elements with the data type of a Hash.

NOTE:
Take the following file db_20220110 as an example.
Y: drinks, which is an AoH
-YYY: The first sub YYY, an element of the root Y, contains multiple key/value pairs, as known as a Hash.
-YYY: The second sub YYY, an element of the root Y, contains multiple key/value pairs, as known as a Hash.

```yaml
---
Date: 2022-01-10

drinks:
  # The first sub YYY
  - item_name: "Black Coffee"
    unit_price: 120
    caffeine_content: 300
    item_no: "IT001"
  # The second sub YYY
  - item_name: "Green Tea"
    unit_price: 100
    caffeine_content: 200
    item_no: "IT002"
---

```

Basic Example: The AoH `drinks` consists of one element with the data type of a Hash.

NOTE:
Take the following file db_20220111 as an example.
Y: drinks, which is an AoH
-YYY: The first sub YYY, an element of the root Y, contains multiple key/value pairs, as known as a Hash.

```yaml
---
Date: 2022-01-11

drinks:
  # The first sub YYY
  - item_name: "Apple Juice"
    unit_price: 110
    caffeine_content: 0
    item_no: "IT003"

Oh! I didn’t know this is possible!
That’s why I developed my plugin “Table to CSV Exporter”.

Twiglet · October 2, 2022, 11:49am

I just started using Obsidian a few days ago as a daily journal and finally got my first dataviewjs query working this morning!

It’s nothing too fancy, especially compared to the query in the OP of this thread, but I just wanted to share my little success. My query creates a table of people mentioned in my daily notes, sorted by most recent mention, a count of mentions, and shows me their relationship to me (friend, family, work).

The thing that made this a bit complicated to setup (for me as a newbie) was that I wanted it be completely automatic and not require any manual editing of YAML. I initially had a field in each person’s note that I would have had to update with the date of our last meetup, but instead I found a way to get the latest daily note and use that as the date.

I also originally had a field for relationship, but since I already had everything set up in folders I figured that there might be a way to inherit that directly from the folder structure, and there was.

So here is what the end result looks like…

In my fault I have a folder called “People” and sub-folders in it that have an individual note for every person like this:

And my query gives me this table:

// Get the latest daily note mentioning this person. Daily notes must be named so that most recent is latest alphabetically.
function latestDailyNote(k) {
	let notes = k.file.inlinks;
	notes = notes.map(n => dv.page(n));
	notes = notes.where(n => n.file.folder == "Daily Journal");
	notes = notes.map(n => n.file.name);
	notes = notes.sort(n => n,'desc');
	return notes[0];
}

dv.table(["Name", "Relationship", "Mentions", "Last Mention"], dv.pages('"People"')
	.where(p => !p.file.link.equals(dv.current().file.link)) // Must use equals(), == fails because not both strings?
	.sort(p => latestDailyNote(p), 'desc')
    .map(p => [
	    p.file.link, 
	    p.file.folder.split("/")[p.file.folder.split("/").length-1],
	    p.file.inlinks.length, 
	    latestDailyNote(p)]))

I’ve probably written this in an unnecessarily convoluted way as I have zero experience in javascript. I’m just happy that the thing actually works, but would welcome any improvements, especially ones that might make it more efficient.

One thing that caused me a lot of problems in particular was working with links. It seems that links don’t necessary sort by the text of the link. Does anyone know how an array of links is sorted? In the end I settled for using dv.page to get the page of the link and then file.name to get the text of the link and sorting on that.

I’m trying to do a dv.table without the counts in the headers.

Anyone has an idea how to do so? I’m seeing

https://github.com/blacksmithgu/obsidian-dataview/search?q=values.length

I’m sure this is stupidly easy question but I’m a javascript novice and I’ve been working an (unrelated) update all night. Googling skills haven’t helped, so can someone assist?

I have an inline dataviewjs script and all I want to do is a case-insensitive string compare. In straight dataview I’ve been doing this: WHERE contains(lower(muddle),“blarg”)

where ‘muddle’ is defined in YAML.

In my inline dataviewjs script I have .where( k => k.muddle == “blarg”) which works as long as the case fully matches but I haven’t been able to force ‘k.muddle’ to lowercase. toLowerCase, lower, etc. have been tried as a result of google searches.

Trying to get some magic with Dashboard++…

Help? Thanks!
