edited, thanks ;)
Note: If your fields aren't being set silently, "invalid" fields are still valid on the model. This means your error messages will be cleared by the "valid" callback as soon as you touch another field. This is easily fixed if you drop the following into the valid callback prior to any work being done:
# If the input field is still in an invalid state, don't remove error
if view.model.preValidate(attr, control.val())
return
(Thanks for the very helpful gist.)
Thanks for the very useful gist.
This can be extended to work with backbone-deep-model, which uses '.' characters as path separators, by quoting the attributes in the control selector in both the valid and invalid sections as follows:
control = view.$('[' + selector + '=' + attr + ']')
becomes
control = view.$('[' + selector + '="' + attr + '"]')
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
_.extend(Backbone.Validation.callbacks, {
valid: function(view, attr, selector) {
var control, group;
control = view.$('[' + selector + '=' + attr + ']');
group = control.parents(".control-group");
group.removeClass("error");
if (control.data("error-style") === "tooltip") {
if (control.data("tooltip")) {
return control.tooltip("hide");
}
} else if (control.data("error-style") === "inline") {
return group.find(".help-inline.error-message").remove();
} else {
return group.find(".help-block.error-message").remove();
}
},
invalid: function(view, attr, error, selector) {
var control, group, position, target;
control = view.$('[' + selector + '=' + attr + ']');
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);
}
}
});
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'
position = control.data('tooltip-position') || 'right'
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 = group.find('.help-inline')
target.text(error)
else
if group.find('.help-block').length == 0
group.find('.form-control').after('<p class=\'help-block error-message\'></p>')
target = group.find('.help-block')
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 ;)
In place of
$(view.el).find()
you can use justview.$()
.
