Product Tag URL Upgrade

I upgraded from 3.5 to 4.10 and it looks like at some point product tag URLS switched. They went from mystore.com/producttag/### to mystore.com/[slug] and are now in the URLRecord table.

It doesn't seem that there's a built-in redirect for this unless I'm missing it. Has anyone come up with an automated way to fix all of these /producttag/ urls which are now coming up as 404?

You're aboslutely right. We missed it. But you can easily add its support in BackwardCompatibility2XController file the same way it's done for other entities

Thanks for that! I edited the file but routing is not working. I'm not sure what to look at next.

private readonly IProductTagService _productTagService;
....
public BackwardCompatibility2XController(IBlogService blogService,
            ICategoryService categoryService,
            IManufacturerService manufacturerService,
            INewsService newsService,
            IProductService productService,
            ITopicService topicService,
            IUrlRecordService urlRecordService,
            IVendorService vendorService,
            IProductTagService productTagService)
        {
            this._blogService = blogService;
            this._categoryService = categoryService;
            this._manufacturerService = manufacturerService;
            this._newsService = newsService;
            this._productService = productService;
            this._topicService = topicService;
            this._urlRecordService = urlRecordService;
            this._vendorService = vendorService;
            this._productTagService = productTagService;
        }

public virtual IActionResult RedirectProductTagById(int productTagId)
        {
            var productTag = _productTagService.GetProductTagById(productTagId);
            if (productTag == null)
                return RedirectToRoutePermanent("HomePage");

            return RedirectToRoutePermanent("ProductTag", new { SeName = _urlRecordService.GetSeName(productTag) });
        }

What am I missing? Do I need to reference this somewhere else in the application?

Hi.
Try to use the "ProductsByTag" route name. You can see the definition of such generic routes here.

I changed the code to

public virtual IActionResult RedirectProductTagById(int productTagId)
        {
            var productTag = _productTagService.GetProductTagById(productTagId);
            if (productTag == null)
                return RedirectToRoutePermanent("HomePage");

            return RedirectToRoutePermanent("ProductsByTag", new { SeName = _urlRecordService.GetSeName(productTag) });
        }

but it still isn't working. I apologize...I'm not very good with routing...

You can see how we fixed it.

Thanks! The route provider piece was what I was missing.

For anyone coming at this in the future, you also need to add this to BackwardCompatibility2XRouteProvider.cs

 //product tags
            routeBuilder.MapLocalizedRoute("", "producttag/{productTagId:min(0)}/{SeName?}",
                new { controller = "BackwardCompatibility2X", action = "RedirectProductTagById" });

Or, see the full fix in Romanov's link above.
