list_folder does not contain property_group

Hi,

I just want to ask why Property_Group is null even though I'm expecting some values. I'm using .Net sdk - list_folder method. Please see the the image below:

Thanks!

Can you share the code that's not working for you? That is, the call where you're adding properties to this file, and the output from that, as well as the list_folder call? Thanks in advance!

Hi Greg,

Sure thing, here it is:

add property (https://api.dropboxapi.com/2/file_properties/templates/add_for_user)==================================================================

{
"name": "Vendor Custom Properties",
"description": "These are custom property for each accounts.",
"fields": [
{
"name": "DateUploaded",
"description": "This is the original Date of the file uploaded",
"type": {
".tag": "string"
}
},
{
"name": "Author",
"description": "This is the original Author of the file uploaded",
"type": {
".tag": "string"
}
}
]
}

Call to list_folder=========================================================

curl -X POST https://api.dropboxapi.com/2/files/list_folder \ --header 'Authorization: Bearer <token here>' \ --header 'Content-Type: application/json' \ --data '{"path":"/Apps/Workorder_QA/Documents"}'

Thank you!

Thanks! I see you're adding the template for the user, and then are listing the files for the user, but it seems you're missing the step of setting the values for that template for the desired file(s). That is, you're missing step 2 below:

The basic flow would be like this:

Call /2/file_properties/templates/add_for_user to add a template.
Call/2/file_properties/properties/add to add property groups for that template to a file (or repeatedly for multiple files).
Call /2/files/list_folder (or /2/files/get_metadata, etc.) later to read them back when listing files.

Thanks! Sorry I forgot to show you that code in my last post but we were able to add the property to the file, the problem is retrieving.

The steps we did were:
upload file via /upload
update file property via /property/add
/list_folder to get the folder content with metadata.

This doesn't contain the "property_groups". However, if you use the /alpha_getmeta it will show you the file metadata together with the "property_groups".

Greg-DB

Apologies, I was misinformed in my last reply.

The property groups aren't supposed to be returned in list_folder (they documentation only shows it because the FileMetadata type sample itself is re-used).

The intent is that they would only be returned by get_metadata when specifying `include_property_templates`. The feature is new though, and we haven't finished rolling it out to the non-alpha endpoint. That will be coming in the future, though I don't have a specific timeline right now.

Sorry again for the earlier inaccurate information!

Hi,

I see, no worries. Thank you very much for responding and clarification

Regards

Greg-DB

Good news, we've finished rolling this functionality out to the non-alpha endpoints, and also actually added it to list_folder as well. The updated ListFolder and GetMetadata arguments are now available in the latest version of the .NET SDK:

Great! Thanks for the update Greg.
