Display a list of files attached to a page

    Table of contents
    1. 1. Sample Output

    This is a working DekiScript block to list the files attached to the Extensions page.

    {{
var page = wiki.getpage( '/MindTouch_Deki/Extensions' );

if( #map.values( page.files ) == 0 ) {
    web.html( "<p>No files are attached to page " .. page.name .. "</p>" );
}
else {
    web.html( "<p>" .. #map.values( page.files ) .. " files are attached to page " .. page.name .. "</p>" );
    foreach( var file in map.values( page.files ) ) {
        web.html(
            "<p>" ..
            __count + 1 .. ") <b>" .. file.name .. "</b><br />" ..
            "<i>Description:</i> " .. file.description .. "<br />" ..
            "<i>Date:</i> " .. file.date .. "<br />" ..
            "<i>Size:</i> " .. file.size .. " bytes<br />" ..
            "<i>URI:</i> <a href='" .. file.uri .. "'>" .. file.uri .. "</a><br />" ..
            "<i>API:</i> <a href='" .. file.api .. "'>" .. file.api .. "</a><br />" ..
            "<i>Mime:</i> " .. file.mime .. "<br />" ..
            "<i>Author:</i> " .. file.author .. "<br />" ..
            "<i>Page:</i> " .. file.page .. "<br />" ..
            "</p>"
        );
    }
}
}}

    Thanks a lot!
    It works Perfect!

    I wanna sort it by file Description, I did this way: list.sort(map.values( page.files ), 'desc') but it doesn't sort it,
    change the order but not on alphabetic way. what can I do?
    Thanks! edited 07:43, 13 Jul 2009

    Gabriel, as I can see from the map values you can sort only by date or name...am I right, steve?

    SteveB says:
    You can sort on any string, date, or numeric field using the second parameter. If you need something more complex, you can also use the 4th parameter which allows you to provide a comparison expression. For example, to sort the on the length of the names, you would do: list.sort(map.values( page.files ), _, _, '#$left.name - #$right.name'). The comparison expression should return a result < 0, if the left value is less than the right value; 0 if they are equal; and > 0 if the right value is greater.

    @giulio, try this instead: list.sort(map.values( page.files ), _, _, 'string.compare($left.description, $right.description, true)'). The problem is probably that .description is a property and not a plain text field. I didn't test this code, so please report back if it works for you. Thx.

    @gabriel84: I had a similar problem on my wiki but it was due to some missing descriptions.
    Please, tell us also what version of mindtouch you're running. edited 05:54, 27 Jul 2009

    Some quick advice please. I am pasting in the script exactly as shown on this page, but I end up with an error message: /content/body/pre, line 1, column 2: "}" expected (click for details)
    I have checked the script multiple times, but can't see where the problem is. I'm sure it must be something simple - any advice? Thanks.

    Is there any way to show in the information listed about a file where in the wiki there are links to that file? Thanks.

    SteveB says:
    @rumjs short answer is no. the database doesn't track incoming links for files. you would have to loop over all pages and check which ones have a reference to the file

    I have a number of files attached to a page with the following naming scheme:
    file1
    file2
    file3
    .
    .
    file10
    file11
    etc etc
    How can I sort on the "mathematical" value of the numbers at the end of the filename, so that they display in order file1,file2,file3,file10,file11 - instead of file1,file10,file11,file2,file3 ?

    I guess it's quite simple, but I've not enough Dekiscript knowledge to figure it out yet!

    Where exactly within the sample script above does one put the list.sort call? I would like to sort the list by date but have no clue where it goes. Thanks!

    I just update to the newest version MindTouch Core v.9.08.3 and this function stopped working.
    I get this error:
    content/body/p/span, line 1, column 507: invalid XmlNode

    Any ideas to fix it? thanks!
