Re: [galaxy-dev] Save data from visualization plugin

23 Apr 2018

      Dear Keith,

I don't know the best way but this work for us. It is used in cooperation with
ACE editor (written in JS):

  	<script type="text/javascript" charset="utf-8">
        var hist_id = null;

        $(function() {
            var address = '${prefix}/history/current_history_json';
            $.get(address, function(resp) {
                if (resp && resp.id)
                    hist_id = resp.id;
            });
            $('#save_btn').on('click', function() {
                var cont = ace.edit('editor').getValue();    # or any other
data, you need to save in new file, here, the data are textual
                var dInputs = {
                    dbkey: '?',
                    file_type: 'auto',
                    'files_0|type': 'upload_dataset',
                    'files_0|space_to_tab': null,
                    'files_0|to_posix_lines': 'Yes'
                };

                var formData = new FormData();
                formData.append('tool_id', 'upload1');
                formData.append('history_id', hist_id);
                formData.append('inputs', JSON.stringify(dInputs));
                formData.append('files_0|file_data', new Blob([cont], {type:
'text/plain'}), $('#editor').attr('file-name'));

                $.ajax({
                    url: '${prefix}/api/tools',
                    data: formData,
                    processData: false,
                    contentType: false,
                    type: 'POST',
                    success: function (resp) {
                        # this part is there to refresh the history panel
otherwise it seems not to turn green
                        window.setTimeout(function() {
                            window.parent.$('#history-refresh-button').trigger('click');
                        }, 3000);
                    }
                });
            });
        });
  	</script>

I hope it helps you.

Best regards,
Martin Demko

My Google-Fu is failing me...
We have a visualization plugin that can also serve as an editor to modify
the data it is visualizing.  What is the best way to save the data from the
visualizer back to Galaxy?
I seem to recall reading (somewhere, sometime) that the REST API could not
do this and the "best" solution is to invoke the upload tool to upload data
into the current history.  I have used the upload tool from the Python and
Blend4J APIs, but I can not find a JavaScript example for invoking the
upload tool.
So two questions:
1. Is the upload tool (still) the recommended way to put data into the
current history via API calls?
2. How do I invoke the upload tool from JavaScript?
Thanks,
Keith
