Does limit_choices_to work outside of the admin interface? Even within the
admin interface, I could not figure out a way to refer, within limit_choices_to,
to fields on the record it was to limit for. In other words, I can hard code
values in there, but not refer to the value of self.whatever_field. Can
limit_choices_to take the name of a function that returns an iterator or
something? It would be neat.
Also, the validator stuff is in a state of flux, and I have been hesitant to
commit much time coding to the current implementation, but that's just me.
I ended up adding some Dojo javascript to get the legal values, in this case
sub-accounts for a buyer, and populate the html select options when the buyer
has been selected.
function fill_accounts(evt) {
el = document.getElementById("id_buyer");
function results_for_post(type, value, evt) {
eval('res='+value);
if (res['is_ok']==true) {
var account_sel = document.getElementById("id_account");
account_sel.innerHTML = res['html'];
} else {
alert ("Problem getting info for " + target.value + ".");
el.focus();
}
}
if (el.value != "") {
dojo.io.bind({
url:
"/admin/manager/participants/"+el.value+"/accounts/?output=json",
method: "GET",
type: "text/javascript",
load: results_for_post,
error: function(type, error) { alert("Error getting accounts: " +
error); },
});
}
return false;
}
It also makes it so they can not enter an illegal value in this view.
Anyway, perhaps the SQLAlchemy branch might someday address this more
comprehensively.
Peace,
