Hello,
i want that the ‘save to file’ node uses the current date in the filename, so i added function in which i add ‘date’ property to the msg, and then in the save node i wrote: “{{msg.date}}.csv”, but the node is not reading the date property and it stores the file with this name: “{{msg.date}}.csv”.
i hope that you can help.
You cannot use the {{ }} syntax in the file name field. You need to generate the filename you want and pass it into the node as msg.filename - as described in the info sidebar of the File node.

It would be helpful if you provided the code you used in the function…
Thank you.
that’s the code i wrote in the function:
var d = new Date();
var t = d.getTime();
var year = d.getFullYear();
var month = d.getMonth()+1;
if(month.toString().length == 1) {
var month = '0'+month;
}
var day = d.getDate();
var hour = d.getHours();
msg.date = t;
msg.filename = "measurements/"+year+month+day+".csv";
return msg;
and it is working well.

Hi all
Can you please provide the code with the node
Thanks
Did you manage to find the right syntax for the node code ?
it shows error, does not work.
Show us the error.
It just says error in javascript code on this line:
var month = '0' + month;
Please export the function node that is showing the error and paste it here. Use the </> button at the top of the forum entry window when pasting it in, to prevent the forum messing with the format.
Also stop node red and start it again in a command window and paste the startup log here. Use the </> button again when pasting that.
It is not an error - more of a "there is something not right".
The problem is the code you have used is "not good". It is declaring var month twice - that is the warning.
Here is an updated version:
const d = new Date()
const year = d.getFullYear()
const month = (d.getMonth() + 1).toString().padStart(2, '0')
const day = d.getDate().toString().padStart(2, '0')
msg.date = d.getTime()
msg.filename = `measurements/${year}-${month}-${day}.csv`
return msg
Thanks, no error message but it still does not save the file name and use it as an external link. :
What am I missing here?
Plan was originally when someone presses Doorbell, it takes a snapshot and send a rich notification to HA with an external link to the jpg. But internet decided to cache the jpg file so I get the same image over and over. Second plan was to use a timestamp that saves every visitor (better plan), but can't find a solution that works with filename and external link. 
I get doorbell_.jpg nonstop

Since you are using HA - I have no idea. AFAIK, most folk here prefer to do everything in node-red.
This is what I (and most other on this forum) see when i import your flow:
As you can see, I have no idea what those nodes are and nor do i known settings they have
NOTE: The original intention of this thread (that is, BTW, over 5 years old), was to generate a dynamic filename in msg.filename - probably for sending to the file node. As you can see from my screenshot does just that.
Just because the msg now has a filename property does NOT mean poking that into a HA node will somehow change a filename somewhere in the bowels of HA.
My only suggestion at this point would be start a new thread and be explicit with what you are doing and that you are using HA etc - OR (probably better) - head over to the HA forum where you can get HA advise on the HA parts of your flow.
