download/save OMERO.table file from remote/to local server

[bhcho]

the result is the query result by

Code: Select all

result = conn.getQueryService().findByQuery(query_string,params.page(0,1))

In this case, is the 'result' an OriginalFile (or not)?
I thought this is not the OriginalFile itself. and that's why I did the following

Code: Select all

fid = result.getId().getValue()
file_remote = conn_remote.getObject("OriginalFile", fid)

Am I correct?

further question.
I got the following error.

Code: Select all

In [146]: fid = result.getId().getValue()     

In [147]: file_remote = conn_remote.getObject("OriginalFile", fid)

In [148]: conn_remote.c.download(file_remote , filename=FNAME_path)

    658
    659             if block_size > ofile.size.val:

Any suggestion?

Best,

What's your query string? Assuming it's returning an original file, then yes.

I thought this is not the OriginalFile itself. and that's why I did the following

Code: Select all

fid = result.getId().getValue()
file_remote = conn_remote.getObject("OriginalFile", fid)

If your query is returning an original file, then these two lines are just reloading the object, and therefore, unnecessary.

Ah, yes. I filed this under [url=https://trac.openmicroscopy.org.uk/ome/ticket/8143]ticket 8143. This is caused by getting the object from conn and then passing it to conn.c. Sorry about that. To workaround, pass file_remote._obj to the download method, i.e.

Code: Select all

conn_remote.c.download(file_remote._obj , filename=FNAME_path)
