One of my API controllers is hitting two databases each on its own context, and I do not want any tables updated until I am satisfied that it is safe.
With that in mind I wrapped the code in a C# transaction scope but when I reached a point where I had to fire scope.dispose, the API call crashed out with a code 500 and any previously executed inserts were not rolled back.
I have successfully applied entity framework core transaction protection to the code block so it is not an issue, but I am curious to know if anyone has tried and succeeded or failed in the same thing.
A quick look online did not show up anything.

Dispose throws away the object. If you want to do a rollback, you call DbTransaction.Rollback Method (System.Data.Common) | Microsoft Docs[^], instead of commit.

That pretty much sums it up. Somehow I got it into my head that if I did not have a scope.complete, then I had to have a scope.dispose to ensure that everything got cleaned up. If I had left it out I would probably have achieved the effect I wanted.
All About Transaction Scope here on CP has both a .Rollback and a .Dispose as capable of rollback in section 20. If I had read this instead of one of the shorter articles I would have seen that I had a choice.
Equally it looks like I would have got an automatic dispose (and rollback) just by throwing an exception as needed.
Good to know.

TransactionScope[^] doesn't have a Rollback method.

True.
TransactionScope makes it possible for plain C# code to be transactional, where DBTransaction is as it says. The factory-method on IDbConnection will return a IDbTransaction, not a TransactionScope.

But Ger's using TransactionScope and Entity Framework.

This is the rollback I was referring to (from the CP article):
using (var scope = new TransactionScope())
{
Transaction.Current.Rollback();
scope.Dispose();
}

I think it's a limitation of EF Core:
As of version 2.1, the System.Transactions implementation in .NET Core does not include support for distributed transactions, therefore you cannot use TransactionScope or CommittableTransaction to coordinate transactions across multiple resource managers.
It's not clear whether that limitation also applies to EF Core on .NET Framework, but I suspect it would.

EF Core's own transaction handling looks like it is doing the job in early testing.

Hi all. I cam having trouble finding any info on the google workbox project and the specific issue I am having with trying to publish updates.
I started on WorkBox 4 and have recently upgraded to the release candidate of version 5 to see if that helps and it did not.
My route is setup as
workbox.routing.registerRoute(
/.*/,
new workbox.strategies.StaleWhileRevalidate({
plugins: [
new workbox.broadcastUpdate.BroadcastUpdatePlugin({
channelName: 'app-update-reload'
})
]
})
);
and, my index.html is supposed to catch the broadcasts using the following code but it never gets called by workbox:
<script>
const updateChannel = new BroadcastChannel('app-update-reload');
updateChannel.addEventListener('message', async (event) => {
console.log(">>>>>>>>>>>>>>>>>> A new update is available!!!!!!!!!!");
});
</script>
So, my problem is that the message event in my index.html never gets called by workbox when there is an update. I can see that the files are being updated when the manifest changes in the browser but the broadcast never happens.
I can manually broadcast from the service worker to test that the index.html is catching the event and it works. however, no matter what I've tried I can't get the StaleWhileRevalidate strategy to broadcast the update and I am pulling my hair out.
I verified that the caching strategy is indeed working and I can't figure out why it won't broadcast.
Any help would be GREATLY appreciated. Thanks!

Hello!
I´m creating a WP site. In the homepage, i´m getting an error:
Quote: Warning: Invalid argument supplied for foreach() in /home2/siilverp/public_html/wp-content/themes/mts_steadyincome/page-home.php on line 108
This is the code of page-home.php:
<?php if(!empty($mts_options['mts_featured_posts']) && !empty($mts_options['mts_featured_post_cat'])) { ?>
<div class="home_article">
<?php
foreach ( $mts_options['mts_featured_post_cat'] as $cat_id ) {
$featured_query = new WP_Query( apply_filters( 'steadyincome_featured_posts_query', array(
'cat' => $cat_id,
'posts_per_page' => 1
) ) );
Now, I found that I have to type var_dump. Then, this appears:

And from there, I dont know what to do. Please, note that I dont know anything about programming, and I don't know who to turn to either, so I came to this forum, I hope that you can help me.
Thanks you so much.

foreach ( $mts_options['mts_featured_post_cat'] as $cat_id ) {
The error message means that the value returned in $mts_options['mts_featured_post_cat'] is not valid for some reason. You need to find out what value(s) is being returned from that reference.

Did you alter the code in the code block you posted?
I checked the array and it contains the records being checked first. Not sure which is line 108 however.
["mts_featured_posts"]=> string(1) "1"
["mts_featured_post_cat"]=> string(1) "1"
I'm not a WordPress guy and haven't written a line of PHP in 4 years, but I suspect you altered the code to make it do something else and need to restore the page code from the original. Or the data in the array is corrupt or your missing something in the original setup of the pages.
WordPress was designed for non programmers to be able to setup a fast website blog. There is no need to edit code, except for the initial setup of passwords and crypt pass phrases. You just run the program and use the system to enter your blogs.

You can avoid plagiarism by submitting only your own original work, and not copying from other people. However this has nothing to do with software development.

So initially when I call my view it pulls the files from the database which users have uploaded and it allows users to delete those files if they don't need them anymore , this is done by when they click on the specific Actionlink, it calls a jquery function which calls my ajax which calls my Remove() Function in my controller , when the files are deleted I append the new list back to the customer.
My Issue: When the new list is appended back, the jquery function is no longer called and it goes directly to the method in my controller. I checked my html anchor-tag in my developer tools of both the appended files and the originally uploaded files and they are identical , I am not sure what is causing this issue, and help will be greatly appreciated.
Here is the anchor tags that work initially when the page is loaded:
<div class="portlet-body form " id="attachments">
@if (ViewBag.file != null)
{
foreach (var x in ViewBag.file)
{
if (string.IsNullOrWhiteSpace(x.FileName))
{
continue;
}
@Html.ActionLink(" ", "Remove", "Chargeback", new { name = (string)x.FileName, filePath = (string)x.FilePath }, new { @class = "fas fa-trash-alt", @id = "uploadsGif" })
@Html.ActionLink((string)x.FileName, "DownloadFile", "Chargeback", new { name = (string)x.FileName, id = "uploads" }, null)
DateTime.Now.ToString("MM/dd/yyyy");
}
}
</div>
Here is my jquery function which is appending my achor-tag/ActionLink:
$("#uploadsGif").click(function () {
debugger;
...
debugger;
$.ajax({
type: 'POST',
url: "/Chargeback/Remove",
dataType: 'json',
data: {
name: name,
filePath: filePath
},
success: function (data) {
debugger;
$("#lblresponce").append("File has been successfully removed");
setTimeout(function () {
$("#lblresponce").empty();
}, 5000)
debugger;
$("#attachments").empty();
$.each(data, function (i, item) {
$("#attachments").append('<a class="fas fa-trash-alt" href=/Chargeback/Remove?name=' + data[0].FileName + ';filePath=' + data[0].FilePath + 'id="uploadsGif"'+'>' + '</a>'); --> ISSUE $("#attachments").append('<a href=/Chargeback/DownloadFile/uploads?name=' + data[0].FileName +'>' + data[0].FileName + '</a>');
});
},
error: function (data) {
}
});
debugger;
return false;
})

Thank you so much, I originally doing it this way ("#uploadsGif").on("click",function(){
})
.

When appending elements dynamically you have to attach the event to a static parent element, and supply a filter which you wish to delegate events to, like this:
This was my solution:
$("#mainDiv").on('click', '.interested', function(){
alert("working");
});

is there a way to grab the name and filepath with jquery?

Yes, look at the actual hmtl generated and you can find how to parse it with jquery.
