I need to check some database values with a periodically_call_remote function.
I want to redirect if some values have already a certain state.
How to do this? redirect_to in the function does not seem to work.
Do you need to do a refresh on the entire page? You could use javascript to update your content.
The following javascript may work as well.
window.location = "http://www.address.com/"
redirect_to in the return function does not work because it redirects the ajax request to the new page, it doesn't tell the browser to redirect the entire page. You will need to either render back some javascript in the controller that causes the page to redirect, or better: add a callback to the periodically_call_remote call that checks the return value and runs the javascript that Ben suggested.
Check this thread:
Rails 3 equivalent for periodically_call_remote
The first answer to use javascript setInterval worked perfectly.

I'm learning Nuxt.js and I'm puzzled by how difficult it seems to be to simply redirect a user to another page from a method that is triggered via a click.
Here is the set up: I'm using Nuxt Auth to authenticate users, once authenticated I want them to be forwarded away from the signup page to another route. I already have middleware set up that redirect logged-in users, but it is only triggered when I refresh the page, not when I first log them in.
I have a method like this:
async login(event) {
event.preventDefault()
try {
await this.$auth.loginWith('local', this.loginData)
// this is where my redirect logic should go
} catch(error) { ... }
}
So far I've tried using this.$nuxt.refresh() which doesn't do anything at all and I've also tried this.$router.push('/route') which seems to hang the page completely. Ideally, I would prefer the refresh approach so that I don't have to specify the landing page for logged in users in multiple places, but I also need to know how to use redirections inside methods, I would have thought it should be the most simple operation imaginable and yet it seems to be difficult to find.
Any tips would be highly appreciated!
UPDATE:
I've found a solution, although it's not an ideal one. I've added an if-statement into beforeCreate that checks this.$auth.loggedIn and if it's true, then it calls this.$auth.redirect('home') when "home" is defined in nuxt.config.js under auth redirect. The reason this solution is not ideal is that it relies on the auth module (as opposed to being a general redirect mechanism).
There's a way in Nuxt to reload the page like so:
this.$router.go(0)
also you can find more information here
if this.$router is not working, try this
this.$nuxt.$options.router.push(url);
So I'm working in express and using hbs as my view engine. I want to make a fetch call from the front end passing form data to my express server. I then want to send a partial with the data sent from the front end to the front end so only that section of the page is updated. Also I want the page to not refresh so I want it to be asynchronous. Is this possible and, if so, how can I do this?
I tried the same long time ago with ajax/jquery, and It could be exausting, extense etc, I recomend to you use vue, react or angular, to handle your front end.
If you want to continue with this you can see this answer:

I am using a call of page.open, and inside that callback I want to go to another URL. Is calling page.open inside page.open okay, or should I use window.location = url in page.evaluate? I tried calling page.open inside a page.open and the script didn't work, and I'm not sure why.
It is always better to use page.open() to navigate to another page instead of using window.location = url from a page.evaluate() call.
It is clearer what happens, because it is easier to read.
There is no way to register a callback when the next page is loaded when window.location is used. One would still need to register to page.onLoadFinished. This is not necessary, because it is already integrated into page.open().
On my error page that I redirect to for any 404s, I'd like to record the url that the user tried to get to.
I've tried this but it doesn't work:
ErrorDocument 404 /error/?url=%{HTTP_REFERRER}
Can anyone tell me how to do it?
Try it with %{REQUEST_URI}. I'm not certain this will work in ErrorDocument since I've never tested it, but it's worth trying.
ErrorDocument 404 /error/?url=%{REQUEST_URI}
There isn't a direct way. Nor a perfect one. But there are few workarounds with PHP.
For example, I currently use a function to create the links of each page. So I would just need to add　file_exists() to the main function (few lines in a single function).
This is the function I would use to create urls:
function url ($Value)
{
// Do some stuff with the url
// [Not showed]
if (!file_exists("/internal/path/".$Value))
{
// Call a function to store the error in a database
error ("404", $Value);
// One way of handling it. Replace '/' for ' ' and search that string.
// Example: "path/to/page" would become "path to page".
$Value=str_replace("/","%20",$Value);
return "http://www.example.com/search=".$Value;
}
else
{
// If the page exists, create the normal link.
return $FullUrl;
}
}
This is my regular way of creating an urls:
<?php url('path/to/page'); ?>
I just thought about this method. It's great as it allows you to find missing pages even IF the user doesn't click on the links. Thank you for making me think about it and now I'll use it in my page (:
Another 'simpler' method (in case you do not wrap links) is that you store last couple of pages visited in $_SESSION['lastpage']; and $_SESSION['lastlastpage'];, if 404 is found then store the corresponding page from which the user tried to access the broken page. It's not a perfect solution since you have to manually find the broken link in the previous page, but at least it gives you some idea of where it is.
Disadvantage: As you can see, both solutions ONLY work with internal broken links.
It would seem there isn't a way.
I'm looking at the controller for the default Delete button in the CButtonColumn class. It manages to return to the previous web-page after deleting a CGridView line and remain on the same page of the CGridView, as opposed to going to the first page. The lines responsible for this in the associated controller seem to be:
if (!isset($_GET['ajax']))
$this->redirect(isset($_POST['returnUrl']) ? $_POST['returnUrl'] : array('admin'));
I would like to create a new custom button that has this behavior (i.e. returning to the previous view without resetting the pagination to page 1), but simply including the above lines of code in the button's associated action does not do the trick. I think I need to send that 'returnUrl' parameter somehow, but I cannot figure out how :)
The 'returnUrl' code you are looking at uses a POST variable for the returnUrl. To use this, you will need to POST that somehow. On the View this code is called from I am assuming there is a <input name="returnUrl"> field in the form. You should make sure this field (populated with the correct URL value) is on all of the Views you are POSTing from in order to access that POST variable in your Controller action.
If you are POSTing to the deleteAction via AJAX, I think you can set the $_POST['returnUrl'] variable with the jQuery AJAX function.
Another way to go might be to use CWebUser's returnUrl SESSION variable instead of this POST variable. I have never done this, but it's built in to Yii so I assume it works OK.
I never really liked the hacky $_POST['returnUrl'] that Gii generates anyway.
ANOTHER thing you could do, possibly, is look at the $_SERVER['HTTP_REFERER'] variable, and use that for the return redirect in your deleteAction. I don't know if that will be set correctly though, with complications from the 302 redirect/rewrites that Yii does.
Good luck!
You can set the return url via the CHtml::link call. Here is an example using delete
CHtml::link(
'Delete',
'#',
array('submit'=>array('delete','id'=>$model->id),
'params'=>('returnUrl'=>'controller/action...'),
'confirm' => 'Are you sure?'
)
);
