[SOLVED] Event trigger

[torn crown]

hi everybody, I want to use Event for my file uploads. I want to save file data in the specific collection by adding files into the specific bucket. would you make an example of what I should do?
I would appreciate any help to understand.

IIUC, you’re asking what the correct Event would be to trigger on file upload to a specific bucket.

I think it should be buckets.[BUCKET_ID].files.*

no i want file parameters i dont know what to write in function file. I use nodejs

[rotund agate]

Not sure what you mean by “file parameters”?

[torn crown]

like size, name, type

[rotund agate]

Ah. I’m not 100% sure, but I’d check in req

[torn crown]

I didn't find:(

May I ask one more question... is there any way to get file from form part in appwrite function? I want to get the file and add to storage in my function. but it says: Cannot read property 'pipe' of undefined

[rotund agate]

So you want to POST the files directly to a Function, then push to Storage from there?

[rotund agate]

Will try to have a look a bit later

sorry to answer late. thanks a lot for your response.

No I want to create a function and set the event to that. whenever I upload the file into the bucket, function triggers.

in that function, I get the file parameters (like size, name, ...) and create a document in my file_detail collection.

but the problem is that I cant find the data about the file that make the function run. there were hints like req. payload, ... but none of them work.

createFile returns a File object with the file metadata: https://appwrite.io/docs/references/1.4.x/server-nodejs/storage#createFile

getFile does the same, you won't need an event to do that.

The workflow would be

1. Upload file and wait the response to get metadata
2. store the data in the collection you want

[rotund agate]

Those functions return the data to the code where you upload the Function. OP wants a Function to be triggered and needs to know the file details there.

[rotund agate]

I just checked, and I do indeed have a File object in req.body

[charred slate]

You're right

The event should be: buckets.[BUCKET_ID].files.*.create to be triggered just when the file is created, you should get a File object as well

Thank you very much @rotund agate @charred slate
