Hi,
I've been trying a lot of options to manage an exception and show an error at admin panel but nothing seems to work.
I'm at the postProcess method of a custom module. After the user sends a csv file through a form and the data is checked (everything works fine here), if an exception occurs I need to show a message, stop and redirect to the same page.
I've tried this:
this->get('session')->getFlashBag()->add('error',$msg);
Tools::redirectAdmin('index.php?controller='.$controller.'&token='.$token);
this:
header("HTTP/1.0 400 Bad Request");
die(json_encode(array( 'error' => array($this->l(' Error') ))));
(that one works but shows a blank page with the message, not the message inside the admin panel)
also this:
$this->context->smarty->assign(array(
'token' => Tools::getAdminTokenLite('AdminModules'),
'errors' => $this->errors
));
$this->setTemplate('ExcelProcess.tpl');
and {$errors|var_dump} at the tpl displays null...
... and many other options.
I can't find anything either about backoffice custom notifications at the PS docs, only about front custom notifications.
Any clue?
Thanks a lot!
Miguel

Adding an error in postProcess() can be achieved by setting
$this->errors[] = $this->l('My error');
or
$this->context->controller->errors[] = $this->l('My error');
during your form submission checks.
Form will be rendered with your error messages into a red box.
If you want to show an alert without reloading the page instead, you'll have to perform an AJAX call to your AdminController, get back a JSON response and render your error message as a result of the execution of the call.

We have a system where customer information is editable in-line.
When someone puts in an email that already exists, I want to return the error message:
Email already exists. <a href='/find-duplicates/id'>Click here to find possible duplicates of this customer</a>
I would like the user to be able to click on the link when s/he sees the error message. The error message is very easy to send; it's rendering the html that's the problem.
Trying to display same kind of link in x-editable field error as #iateadonut.
For anyone wanting to display html in x-editable errors, assuming you have the error with html sent back from server with response status code different from 500 (400 maybe) try :
$(function() {
$('#your_field_id').editable({
error: function(response, newValue) {
if(response.status === 500) {
return 'Service unavailable. Please try later.';
} else {
var error = $.parseHTML( response.responseText )
$(".editable-error-block").html(error)
}
},
});
})
Mostly html parsing response error and injecting it inside x-editable error block.
Found in x-editable doc, options.
I'm trying to secure my meteor app with iron-router, here's my onBeforeAction function:
this.route('manageUsers', {
path: '/panel/user_management',
layoutTemplate: 'panel',
onBeforeAction: function(){
if((Meteor.user() === null)||(Meteor.user().role !== 'superAdmin')){
Router.go('signIn');
throwAlert('You dont have access to see this page', 'notification');
}
}
});
When I'm trying to go to /panel/user_management subpage by pressing a link button everything goes fine (user is redirected etc.), but when I type the path directly in my browser (localhost:3000/panel/user_management) and hit enter user is not getting redirected and I receive in console Exception in defer callback error. Anyone know what I'm doing wrong?
For additional information, this view lists me all users registered. When I go to this path normally (without error) I see complete user list. When I receive error template doesn't appear in > yield.
Finally, I've solved this - the problem was wrong if statement, here's the correct one:
if((!Meteor.user())||(Meteor.user().role !== 'superAdmin')){}
I am able to render my specified error pages in my modules, but I can't get error layouts outside of my modules.
It's quite strange, in my main config I have:
'errorHandler'=>array(
'errorAction'=> '//site/error',
),
I tried to see if it is pointed to the right file by changing it to //site/contact, and see if it renders the contact page if error. And it does show.
So the path is correct, then how come it's not showing the error page? It shows the default white page with exception error. The exception page is what im expecting, but how it's formatted is not.
public function actionError()
{
$this->layout = '/layouts/main';
if($error=Yii::app()->errorHandler->error)
{
if(Yii::app()->request->isAjaxRequest)
echo $error['message'];
else
$this->render('error', array('error'=>$error));
}
}
Your user role doesn't have rights to access actionError() in controller.
In your site controller, You can see a function called public function accessRules().
Check error is added for some user role, or it's for admin only.
If error not found, then add it for user roles.
Example:
public function accessRules()
{
return array(
array('allow',
'actions' => array('index', 'view', 'error'),
'users' => array('#')
),
..
..
..
}
You need to create a errorXXX in views/system. The XXX stand for the error code, in this case most likely a 403. For more information see this page on the Yii site.
I'm having a bunch of problems getting jQuery's .on to work with my Rails ajax link.
Specifically, I've got this link:
<div id="item_7_tools" class="item_tools">
<a rel="nofollow" id="book_item_7" data-remote="true" data-method="post" class="book_link" href="bookings">Book this item</a>
</div>
I've trimmed some of the text in the HTML, but suffice to say that that, and my controller response work.
I click "Book this item", it goes off to the controller, the controller does its magic, and sends back my partial that replaces the contents of that div.
So I'm now trying to replace the contents with an ajax spinner while the loading is working, and that's where its going pear-shape.
I'm trying this initial bunch of jQuery code just to make sure I've got my javascript working:
$('div.item_tools')
.on('click', 'a', function() {
console.log("clicky click")
})
.on('ajax:beforeSend', "a", function() {
console.log('the a in div.item_tools is sending its ajax command');
})
.on('ajax:complete', "a", function() {
console.log('ajax request completed');
})
My understanding of that, is that when I then click any link (a) that lives within an element with the item_tools class, it will bubble up to this function, and then log the message into the console. Similarly, a link that has triggered an ajax request will get the same treatment...
(And assuming I can get that to work, then I'll go to work doing the ajax loader spinner).
The behaviour I'm seeing instead, is that when I click the link, there are no messages appearing in my console (trying this on both firefox and chrome), and my ajax link goes off and does its stuff correctly. Just completely ignoring the javascript...
Is this because my clicking the ajax link somehow has blocked the click event from bubbling up? I know that there's a way to do that, but I don't think I've done it anywhere knowingly. Unless OOTB rails/ujs does that?
So my questions:
Is there a way to tell what has had a binding attached to it?
What am I doing wrong with my javascript?
Thanks!
I use this all the time... and it seems to work fine.
Have you tried adding one that's .on('ajax:success')?
Besides that try putting the . for each line on the previous line...? It's possible that it gets to $('div.item_tools') and then auto-inserts a semi-colon as per javascript's standard... Although if that were the case I'd expect it to give you a JS error about the . on the next line. In any case try changing it to:
$('div.item_tools').
on('click', 'a', function() {
console.log("clicky click")
}).
on('ajax:beforeSend', "a", function() {
console.log('the a in div.item_tools is sending its ajax command');
}).
on('ajax:complete', "a", function() {
console.log('ajax request completed');
})
If worse comes to worse try just doing:
$("a").on("ajax:success", function(){
console.log('ajax:success done');
})
And see if it works without the event delegation...
Then change it to this:
$(document).on("ajax:success", "a", function(){
console.log("ajax:success with delegation to document");
})
And see if delegation works all the way up to document instead of just your item_tools
Are you sure that you've named everything right? it's div.item_tools a in your markup?
Turns out that the javascript was being triggered before the DOM had loaded, which meant that stuff weren't being bound...
$(function () {
$('div.item_tools')
.on('click', 'a', function itemToolsAjaxy() {
console.log("clicky click");
})
.on('ajax:beforeSend', "a", function() {
console.log('the a in div.item_tools is sending its ajax command');
$(this).closest('div').html('<img src=/assets/ajax-loader.gif>');
})
});
Added the $(function()) right at the beginning and it delayed the binding until after the DOM had loaded, and then it started working.
Figured this out by using the Chrome developer tools to stick a break on the div.item_tools selector and watched as the browser hit that even before the DOM had been loaded. /facepalm
(I removed the .on('ajax:complete') callback, because it turns out that there's a known limitation where the original trigger element no longer exists because it had been replaced, so there's nothing to perform the callback on. Not relevant to my original problem, but I thought I'd mention it.)
As far as i'm aware, you can either do ajax stuff 2 ways:
By using :remote => true
By using jQuery's $.ajax (or $.post).
With number 2, make sure to change your href='#'
My suggeston is to remove the :remote => true and manually make a jQuery ajax call. That way you can use beforeSend, complete, etc.
If i'm way off track here, someone please help clarify things for me as well.
Whats the smartest way to add a ajax loader gif image in the center of screen every time my Sencha 2 app does a ajax request? Should be some kind of code snippet which should check if a internal Javascript counter which keeps track of all open Ajax requests is > than 0 and thereby show the loader gif
Normally I just put the code below before a ajax request.
Ext.Viewport.add({
masked: {
xtype: 'loadmask',
message: 'A message..',
indicator: false
}
});
You might want to extend the ajax class and add it there to get this to work for every ajax request.
