how to get file_id, file_size metadata using filename gotten from file chooser (python)

When calling files_get_metadata like this, you need to supply the full path and name for the file. If you don't supply the path to a file that exists, you'll get this not_found error.

The Chooser only returns the name of the file, and not the path. So, if the file happens to exist in root, your files_get_metadata call will happen to find it. If it doesn't though, you won't have the right path, and the call will fail.

Alternatively, if you're using the web Chooser, you can get the "id" returned by the Chooser and pass that to files_get_metadata instead. The "id" was recently added to the Chooser though, and isn't officially documented, so I can't promise it will be reliable.

Yes, using the JavaScript Chooser, get the 'id' from the result, just like you get the filename. Then, pass that directly into files_get_metadata.

Hello Greg,

Just tried but fileid came up empty.

Here is the code I am using to get the values from returned response:

filename=obj.name;
filepath=obj.link;
fileicon=obj.id;
filesize=obj.size;
fileicons=obj.icon;
filethumbnail=obj.thumbnailLink;

I am not sure how to save the thumbnail image.  Should I save it as a file or is it in a string (as in a link) format?

Q

Can you share the rest of your Chooser code? Accessing .id on the returned file object should give you the file ID.

Also, thumbnailLink is a URL that points to the data for the thumbnail. What you with that is up to you. E.g., you can make an HTTPS request to it to download the thumbnail data, and display it in your app.

Here is what I have:

<script type="text/javascript" src="https://www.dropbox.com/static/api/2/dropins.js" id="dropboxjs" data-app-key="kuxx5m7ap1npv24"></script>
<script>
var options= {
multiselect: true,
//extensions: ['.png', '.jpg', '.mvp3', '.mvp4', '.doc', '.xls'],
linkType: 'preview',
success: function(files) {

var filenames;
var filepaths;
var fileids;
var filesizes;
var fileicons;
var filethumbnails;
 
//Parse file names and file paths from files. Store data into arrays.
var obj = files;

filenames=obj.name;
filepaths=obj.link;
fileicons=obj.id;
filesizes=obj.size;
fileicons=obj.icon;
filethumbnails=obj.thumbnailLink;
 
document.getElementById('linkfile').value = filepaths; 
document.getElementById('namefile').value = filenames;
document.getElementById('idfile').value = fileids;
document.getElementById('sizefile').value = filesizes;
document.getElementById('iconfile').value = fileicons;
document.getElementById('thumbnailfile').value = filethumbnails;
 
alert(filepaths);
alert(filenames);
alert(fileids); 
alert(filesizes);
alert(fileicons);
alert(filethumbnails);
};
},
};
$(document).ready(function() {
var button = Dropbox.createChooseButton(options);
document.getElementById('uploadDB').appendChild(button);
});
</script>
<div id="uploadDB"></div>

I can get name, link, icon/thumbnail not size and nor id.

Q.

Thanks! I see two things that will likely make this not work:

1) The `files` variable given to your `success` callback is an array of files, so you can't directly access the information about specific files on it. You'll need to either iterate over it, or access individual items, e.g., `files[0].id`.

2) You're never actually setting `fileids`. You're instead setting `fileicons` twice.

Good catch.  I tried using var obj = files[0]; to get the first file and I was able to get the fileid.  But the filesize is still empty.  Is it possible to get filesize here?  Maybe I can get it later using fileid.

I am trying to find instructions on getting metadata using fileid in python. program.  You are so knowledgable, do you have any hints for me?  I cannot pin point any good reads on it.   Thanks again.

Q

Thank you so much.  You have been really helpful.  I am able to get all the metadata I was looking for.  

Regards,
