File_column question

Rails
1

When using file_column, I found a situation where I wanted to hard code
what file the user uploads. So I wanted to do something like this:

http://pastie.caboo.se/11733

So I wanted it to statically point to that file… however, this
doesn’t work when I hit upload. Any idea what I’m doing wrong?

Thanks,
Ben L.

do you want still want to have a “browse” button? or nothing at all for
the
user to select an image?

if that is the case, just set the value of “picture” to the img path in
your
upload controller as you can’t set the value for a file upload in most
broweser…

go to http://gotapi.com/ to read about HTML and other languages…its
pretty
handy

lookup “input” under HTML and you’ll find that The VALUE attribute
specifies the name of the initial file, but it is typically ignored by
browsers as a security precaution.

I use file_column to upload images from either the file system or via a
URL

check out my site at www.blogsaic.com and upload a tile both ways…to
see
how it works…

I upload the file system img the normal way, but the URL way is all done
in
the controller, by simply over writting the file column attribute for
the
image, one the url is verified a legit url to an image

give me an email if you want some code snippits

Dion - thanks again for the help.

Dion was right - you can’t set the value of a file field. So instead,
I placed a file_column_field down, and when the user put the source in
there, it would then “hide” itself (change the location of it, don’t
hide it, safari doesn’t like you hiding a file field), and a new
file_column_field would be put in it’s place. Then when I hit upload,
it would upload all of the files the user wanted to upload.

The desired effect is exactly like this:

except done in rails.

did you have to create a loop in your controller to save each of the
images
uploaded?

you got me interested in this, so I was mucking round and use the
multifile
script to upload multiple files

I have this in my controller, so it only saves the second file uploaded

@tile.img_name = params[:file_1]

it works, but how do you save each of the files in your controller?
do you just create a new record for each one, giving them the same
attributes except for the img name?

cheers
