Thanks for the code @webdevbyjoss
This should work fine with bootstrap 3
_.extend Backbone.Validation.callbacks,
valid: (view, attr, selector) ->
control = view.$('[' + selector + '=' + attr + ']')
group = control.parents('.form-group')
group.removeClass('has-error')
if control.data('error-style') == 'tooltip'
# CAUTION: calling tooltip('hide') on an uninitialized tooltip
# causes bootstraps tooltips to crash somehow...
control.tooltip 'hide' if control.data('tooltip')
else if control.data('error-style') == 'inline'
group.find('.help-inline.error-message').remove()
else
group.find('.help-block.error-message').remove()
invalid: (view, attr, error, selector) ->
control = view.$('[' + selector + '=' + attr + ']')
group = control.parents('.form-group')
group.addClass('has-error')
if control.data('error-style') == 'tooltip'

control.tooltip
placement: position
trigger: 'manual'
title: error
control.tooltip 'show'
else if control.data('error-style') == 'inline'
if group.find('.help-inline').length == 0
group.find('.form-control').after('<span class=\'help-inline error-message\'></span>')

target.text(error)

group.find('.form-control').after('<p class=\'help-block error-message\'></p>')

target.text(error)
LN #3 and LN#17
control = view.$('[' + selector + '=' + attr + ']')to
control = view.$('[' + selector + '="' + attr + '"]')it would allow for complex selectors
If you are going to have input fields names like this,
...
<input name="clients[address][street]" type="text" >
...The following code should work well.
_.extend(Validation.callbacks, {
valid: function(view, attr, selector) {
// compose the attr - for complex situations
var arr = attr.split('.'),
el = '';
for (var i = 0; i < arr.length; i++) {
if (i === 0) el += arr[i];
else el += '[' + arr[i] + ']';
}
var control, group;
control = view.$('[' + selector + '="' + el + '"]');
group = control.parents(".control-group");
group.removeClass("error");
if (control.data("error-style") === "tooltip") {
if (control.data("tooltip")) {
return control.tooltip("hide");
}
} else if (control.data("error-style") === "inline") {
return group.find(".help-inline.error-message").remove();
} else {
return group.find(".help-block.error-message").remove();
}
},
invalid: function(view, attr, error, selector) {
// compose the attr - for complex situations
var arr = attr.split('.'),
el = '';
for (var i = 0; i < arr.length; i++) {
if (i === 0) el += arr[i];
else el += '[' + arr[i] + ']';
}
var control, group, position, target;
control = view.$('[' + selector + '="' + el + '"]');
group = control.parents(".control-group");
group.addClass("error");
if (control.data("error-style") === "tooltip") {
position = control.data("tooltip-position") || "right";
control.tooltip({
placement: position,
trigger: "manual",
title: error
});
return control.tooltip("show");
} else if (control.data("error-style") === "inline") {
if (group.find(".help-inline").length === 0) {
group.find(".controls").append("<span class=\"help-inline error-message\"></span>");
}
target = group.find(".help-inline");
return target.text(error);
} else {
if (group.find(".help-block").length === 0) {
group.find(".controls").append("<p class=\"help-block error-message\"></p>");
}
target = group.find(".help-block");
return target.text(error);
}
}
});
So I hate to be that guy but, @driehle, could you add a license to this gist?
We are actually using this gist in production for exactly what it's written for - binding Backbone.Validation to twitter bootstrap. It works like a charm. However, the lawyers recently reviewed our code and turned up this gist not having a license. Sigh.
Also not sure if you're aware of this but the Backbone.Validation FAQ actually links directly to this gist: http://thedersen.com/projects/backbone-validation/#faq/how-can-i-use-it-with-twitter-bootstrap. Perhaps there's an opportunity here to promote this gist to its own full-fledged project and get that FAQ updated?
Ping @driehle.
(Sorry to be a pest; I blame The Laywers.)
This is getting enough attention that it feels like it should become a proper github project with issues and pull requests, and maybe an organization with multiple committers to maintain it...
Agreed with @brycefisher 👍
@scottbale it's most probably way too late for you (sorry, somehow I never got a notification for your comment), but I have added the MIT license!
@brycefisher I'd rather use Angular nowadays than backbone ;)

Same as above in plain JavaScript, possibly will be useful for someone like me who writes in plain JavaScript but still searches for rendering Backbone.Validation messages for Twitter Bootstrap forms
