I have this working, but not the most user friendly. The case is there is a combination of fields that must meet a criteria, uniqueness in this case. The problem I am finding is that the rules are all attached to fields, where this case really applies to the form in general.
In this example, an end user is adding a Member record. A member is a combination of a User and a Group. Users can join many groups, groups have many users. A user cannot join the same group twice, so the alternate, natural key to the Member database table is usr_id, group_id. The form has fields with id of user and group. While it does work, when an error is detected, the field you just changed is marked with the error. The other field in the pair is not marked as being invalid. If I go and change the other field to make a valid combination, the other field still shows as being in the error state. Looking for ideas to implement an N field validation nicely. (I used a ClassRule for single field unique checks, but that doesn't help here.) Thanks, Ted ------------------------ var constraint = ['user', 'group']; $.each(constraint, function(index, value) { $("#" + value).rules("add", { remote: { url: "/myapp/unique/composite", type: "get", data: { classname: function() { return $("#classname").val(); }, constraints: function() { var result = ""; $.each(constraint, function(i, v) { if (i > 0) { result = result + ";"; } result = result + v + ':' + $("#" + v).val(); }); return result; }, id: function() { return $("#id").val(); } } }, messages: { remote: "The combination of " + constraint + " must be unique." } }); -----------------------------
