    Listing permissions per user/group

    This week I came cross this question on Episerver World forum https://world.episerver.com/forum/developer-forum/Episerver-Commerce/Thread-Container/2019/5/get-rolepermission-data/ , and while it is not Commerce-related. it is quite interesting to solve. Perhaps this short post will help the original poster, as well future visitors. As in the thread, I replied the first piece to solve the puzzle: You can use PermissionTypeRepository to get the registered PermissionTypes, then PermissionRepository to figure out which groups/users have a specific permission  If you want to list permissions granted to a specific role or user, it is just a simple reversion using a dictionary: As suggested above, we use PermissionTypeRepository to list the registered PermissionType(s) , and then for each PermissionType we get…

    IContentLoader.Get(contentLink) is considered harmful for catalog content.

    A while ago I wrote about how you should be aware of IContentLoader.GetChildren<T>(contentLink) here. However, that is only half of story. IContentLoader.Get<T>(contentLink) is also considered harmful. Not in terms of it causes damage to your site (we would never, ever let that happen), nor it is slow (not unless you abuse it), but because it can behave very unexpectedly. As you might already know, catalog content fully supports language versions, which means a catalog might have multiple languages enabled, and each and every catalog item in that catalog (node/category, and entry) will be available in those languages. However, those languages are not equal, (only) one is master language. What’s the difference…

    Control the thousand separator for Money in Episerver Commerce

    If you are selling goods in multiple markets which same currency but with different languages, such as EuroZone, you might notice that while everything looks quite good, except that the thousand separator might be off from time to time: it is always the same and does not change to match with the language, so sometimes it’s correct, sometimes it’s not. Let’s take a step back to see how to properly show the thousand delimiter  In the United States, this character is a comma (,). In Germany, it is a period (.). Thus one thousand and twenty-five is displayed as 1,025 in the United States and 1.025 in Germany. In Sweden,…

    Speed up catalog routing if you have multiple children under catalog

    A normal catalog structure is like this: you have a few high level categories under the catalog, then each high level category has a few lower level categories under it, then each lower level category has their children, so on and so forth until you reach the leaves – catalog entries. However it is not uncommon that you have multiple children (categories and entries) directly under catalog. Even though that is not something you should do, it happens.  But that is not without drawbacks. You might notice it is slow to route to a product. It might not be visible to naked eyes, but if you use some decent profilers…

    Refactoring Commerce catalog code, a story

    It is not a secret that I am a fan of refactoring. Clean. shorter, simpler code is always better. It’s always a pleasure to delete some code while keeping all functionalities: less code means less possible bugs, and less places to change when you have to change. However, while refactoring can bring a lot of enjoying to the one who actually does it, it’s very hard to share the experience: most of the cases it’s very specific and the problem itself is not that interesting to the outside world. This story is an exception because it might be helpful/useful for other Commerce developer.

    Commerce batching performance – part 2: Loading prices and inventories

    UPDATE: When looked into it, I realize that I have a lazy loading collection of entry codes, so each test had to spent time to resolve the entry code(s) from the content links. That actually costs quite a lot of time, and therefore causing the performance tests to return incorrect results. That was corrected and the results are now updated. In previous post we talked about how loading orders in batch can actually improve your website performance, and we came to a conclusion that 1000-3000 orders per batch probably yields the best performance result. But orders are not the only thing you would need to load on your website. A…

    Speed up your catalog indexing performance – part 2

    Almost two years ago I wrote part 1 here: https://vimvq1987.com/speed-catalog-entries-indexing/ on how to speed up your catalog indexing performance. If you have a fairly big catalog with frequent changes, it might take longer time than necessary to build the index incrementally. (Rebuild index, in other hands, just delete everything and rebuild from scratch, so it is not affected by the long queue in ApplicationLog). I have seen some cases where rebuilding the entire index, is actually faster than waiting for it to build incrementally. The tip in previous blog post should work very well if you are using anything lower than Commerce 11.6, but that is no longer the case!

    Getting all non published variations

    I got a question from a colleague today: A customer has multiple languages (8 of them). They need to make sure all variants are published in all languages. That is of course a reasonable request, but there is no feature builtin for such requirement. But good news is that can be done with ease. If you want to try this as practice, go ahead – I think it’s a good exercise for your Episerver Commerce-fu skills. To do this task, we need the snippet to traverse the catalog from here https://leanpub.com/epicommercerecipes/read_sample

    Watch out for Singletons

    If you are a seasoned Episerver developer, you should (and probably, already) know about the foundation of the framework: dependency injection. With the Inversion of control framework (most common, Structuremap, but recent versions of Framework allow much more flexible options), you can easily register your implementations, without having to manually create each and every instance by new operator. Sounds great, right? Yes it is. And Episerver Framework allows you to make it even easier by this nice ServiceConfiguration attribute: [crayon-5da937798766a768843019/] so your class will be automatically registered, and whenever you need an instance of MyClass, IoC framework will get the best instance for you, automatically, without breaking a sweat. Isn’t it nice?…
