File download via endpoint

[scho]

Hi everyone,

I'm trying to accomplish a file download via a netzke endpoint/ajax. E.g. I want to export the data of a grid panel into excel.

In my opinion, the 'classic/none-ajax' way would be to create a controller and do all the rendering/exporting there. So a simple button that changes window.location would do the trick.

On the other hand, that would duplicate a lot of code, since I already have a lot of things in my component, that I could use (e.g. get_data/get_records).

I think, doing it via an endpoint would be much nicer & cleaner. So, has anyone done such a thing or could share some ideas?

cheers,

Georg

Georg,

What about doing the following in an endpoint: 1) generate the file, 2) store it in a place accessible by HTTP server, 3) return the file's URL from the endpoint, 4) setting window.location to that URL?

Hei Denis,

I thought about something similar as well, but the file must not be public accessible. 

I could 'hide' it somehow by random filename/dirname, but I think I'll create a user attachment model and I'll store it there.

Then a user could also access all his exported files. This could be a nice feature for the future :)

I also found some strange hacks with iframes, etc. but I don't think this would end up in a nice & clear solution.

Thanks for your thoughts!
