GridFS file exists with with name?

[kevin]

can you guys add a method to check if a file already exists with a given file name? or make get_last_version return None if filename does not exist?

i want to check if a file with a filename exists otherwise i want to fetch and insert into GridFS. but there is no method to check if a file with filename exists?
thanks

Which driver/package are you referring to?

get_last_version raises NoFile if no such file exists, so you can just
catch that. Or you can manually query the files collection looking for
the filename

[kevin]

it will be nice/convenient if the filesystem supported a method to check if there is a file with filename instead of trying to catch exceptions, or try to read fs.files collection

Feel free to file a jira should be easy to add.

great - thanks

wouldn't it be better if it returns the file instance or None instead of True or False?
