Daily Note: code for going back a day doen't work

What I’m trying to do

I often need to go back to the previous day and review or update a previous Daily Note. I found a function in a “how to” video, but it doesn’t work. Below is the code. Can anyone tell me what is broken?

Things I have tried

%<fileDate = moment(tp.file.title, ‘YYYY-MM-DD’)subtract(1,d).format(‘YYYY-MM-DD’) %>Yesterday

@ChildsB

%<fileDate = moment(tp.file.title, ‘YYYY-MM-DD’)subtract(1,d).format(‘YYYY-MM-DD’) %>Yesterday

This could work (using the community plugin Templater)… and applied to a note where the title follows the format YYYY-MM-DD:

[[<% moment(tp.file.title, "YYYY-MM-DD").subtract(1, 'd').format("YYYY-MM-DD") %>|Yesterday]]

Or this:

[[<% tp.date.now("YYYY-MM-DD", -1, tp.file.title, "YYYY-MM-DD") %>|Yesterday]]

See here for more info about tp.date.now()

First of all you got a syntax error in your code.

@ChildsB

%<fileDate = moment(tp.file.title, ‘YYYY-MM-DD’)subtract(1,d).format(‘YYYY-MM-DD’) %>Yesterday

Instead of %< the opening tag for Templater script is <%.

Anyway, better solution maybe the following using dataview plugin, for it also covers the possibility of missing days in your logs, just in case.

<< `$= dv.pages('"<your daily log folder>"')
.where(p => p.file.day && p.file.day < dv.current().file.day)
.sort(p => p.file.day, "desc").file.link.limit(1)` | `$= dv.pages('"<your daily log folder"')
.where(p => p.file.day && p.file.day > dv.current().file.day)
.sort(p => p.file.day, "asc").file.link.limit(1)` >>

Resulting in something like << 2024-10-01 | 2024-10-05 >>.

Thank you. I have templater, although I haven’t gotten productive with it yet. The code is in a template that I created. The first line, which is simply the date and time works fine. The next line of code is what I have shared. I will give your suggestion to try the .now function. I will update post later today.

THANK YOU

Hi, I like the idea of using Dataview, especially the idea/function of scrolling dates back and forth. I have been struggling with Dataview, but this may be a good catalyst in helping learn it more effectively. Thank you.

I will update post shortly.

Note that any code executed by Templater will produce the correct previous/next link at the time of inserting the template. So unless you want it to always refer to yesterday and tomorrow for any given date, a dynamic solution like the one using Dataview would be a better option.

Templater is never “re-executed” at a later time, so if you originally had the previous note to be a month earlier, and later on added a note in between those two notes it wouldn’t be linked by the previous link.

Great heads on the Templater notation executable (no pun intended).

Dataview is another plugin that I have and do not have a full appreciation for yet, but need to develop.

[ChildsB]

I tried the code but it didn’t work. All of the examples that I have seen for Dataview code begin and end with \. The example that you provided begin and end with << >>.

What am I not understanding?

Thank you in advance.

[Mephi]

You can leave the << >>. In my example it was just to have some visual indicator that you are going forward or backward, but it’s not part of the coding.

EDIT: The code snippet I provided will work in any case, as long as you

• have installed and activated Dataview plugin
• your daily notes have a date in their title
• you copy and paste the snippet as it is directly in your template (or any other note with a date in its title)
• you replace the string <your daily log folder> with the path to the folder you store your daily notes in, so it will look something like this dv.pages('"CALENDAR/DAILY"')
• you even can leave it blank (regardless of using a folder for your daily notes or storing them under root), when it will look like dv.pages()

If you run Dataview, would this work for you? Can be customized, of course.

`="[[" + dateformat(date(yesterday), "yyyy-MM-dd") + "|◀️🅨]]"` | `="[[" + dateformat(date(today), "yyyy-MM-dd") + "|🅣▶️]]"`

Ahh, thanks for explaining the << >>. I read it that way when I first saw your post, but my brain checked out and I got lost in my own entanglement. I’ll experiment and post a reply over the weekend.

Thank you…
