Hi,
I didn't define an AppRoot for my blog application (I'm on 0.7.2) , so
I get a double / -> // for magic components for these statements in
erlyweb_view.et
It concerns these statements (grepped):
erlyweb_view.et:14:<% a([AppRoot, Model, <<"new">>], <<"create new">>)
%><br><br>
erlyweb_view.et:23:<% a([AppRoot, Model, <<"delete">>, Id],
<<"delete">>) %>
My yaws.conf looks like this:
< server localhost >
port = 8000
listen = 127.0.0.1
docroot = /home/luser/projects/blog/www
appmods = <"/", erlyweb> ## !!
<opaque>
appname =
blog
</opaque>
< /server >
I tried hacking the join/1+2 function to not accept an element in the
Args list parameter if a "" =:= [] is present, like this:
%% A helper function
join(Args) ->
join(Args, []).
join([], _) -> [];
join([Last], Acc) ->
lists:reverse([Last | Acc]);
join([First | Rest], Acc) when First =:= [] -> %% !!
join(Rest, Acc);
join([First | Rest], Acc) when First =/= [] -> %% orig.
join(Rest, [[First, $/] | Acc]).
But it's not working as I expect. It should filter out null values.
I think a nice filter for [] =:= "" might work for a/2 in module
erlyweb_html.
What do you guys think? The cost is only O(1) since the double slashed
part of "//component/function/par" makes firefox think the target is
htttp://component/function/par
I haven't tested on other browsers except opera and firefox (covers
all of mozilla methinks). Both fail.
I'll try to fix this using a filter on the a/2 definiton in
erlyweb_html.
