  • It’s no reddit in terms of quantity but honesty I’ve had higher quality topics and discussions here than there. Lemmy/kbin might not have taken off in the mainstream to offer a variety of subjects but when it comes to tech and software I think it’s covered well enough and people are generally nicer about it. The main problem is lack of (remotely) good seach function, I dont think the threads are getting indexed by google and the on-site search is atrocious.

    I don’t know of any discord programming communities, I wish forums were still a thing but the only live one I know of is the jellyfin one after they moved from reddit. Other than that it’s here or the various subreddits





  • Additional question - I said at first that the “Service” should be doing the mandatory checks like uniqueness validation or whether the fields are filled in properly with good values, but is even that a good approach?

    Instead of implementing this in every service that might create a new Movie (and it could be from different sources - import from file, different APIs, background worker, etc), wouldn’t it make more sense to add these checks to the repository itself so they always gets called?

    Alternatively, do we have to handle a constraint violation in every service or could we just have the repository return a result with failure if it happens?

    In short, once I start thinking in this way I start to wonder why even have a separation between repository and service.



  • I’m not that familiar with newer c# code and only recently started with result pattern but tbh, I can’t tell what is this code supposed to do. Does opt resolve to true or false in this case? Why do you want TestStringFail to always execute, and what should it return? Why is opt.None true when it was initialized with a valid string value, what does None even mean in this context?






  • A bit late to this thread but what helped me a lot was when I started doing TDD. By testing my code against tests before its fully done or even implemented in the main app codebase (so to speak), I could break down individual tasks in it more easily and see how its interior parts work. It seemed easier to separate it into SRP areas since they’d have to stick to the unit test for that responsibility. Do keep in mind you can take it too far and overengineer it in this way but it was a good kick in the butt to get me to think in a different way.



  • In the context of this small app im writing category is unique by name already so I can just use that if I wanted to go the string route, but agreed - yours is probably the standard way, youtube/reddit do it like that after all.

    I’m still wondering about the technical implementation of it - where would you generate the string? Manually in backend before each save, probably using a locking mechanism to prevent accidentally creating 2 identical IDs at the same time? I’d have to do a db hit to make sure it doesn’t exist already every time, right? Maybe I just try to insert and see if it crashes due to the uniqueness index? Maybe I use a store procedure in the database to get a unique ID? Do I just hash the timestamp or sth like that?

    Whether I generate a number or a string, feels like I always open it up to many issues.






  • You can kinda see this in things like modding communities or anything piracy related too. Users just want easy solutions even if it’s at the expense of creators, and creators are doing it more and more for money rather than any personal drive or satisfaction. I can’t believe we’ve reached a point where even mods are being locked behind paywalls, need to be commissioned or sometimes have entire teams funded by patreon to work on them, it’s just another business nowadays.



  • The switch case was based on an enum but it is what I want to get rid of. In the end I ended up doing what you wrote there, expect instead of casting I’m just writing

    case Type.Int: return MyTypedMethod<int>(args)
    case Type.IntNull: return MyTypedMethod<int?>(args)
    // etc for another 10+ different types
    

    It just feels like I’m doing something wrong if i have to manually handle every case in a switch (or if else) statement and I was wondering how could I write, for example, a method that would do the conversion from Type.Long to System.Int64 for me, and then I just pass that type into the generic method instead of having to manually translate it into a type every time it is used.

    However, if I have to use reflection maybe hardcoding it manually every time is actually faster and easier to debug so maybe i’m just overthinking it.

    That c# 7 structure looks interesting but not sure it solves my issue, I need to get to the part where i have the generic type T in the first place. I dont know how to get a “T” out of a custom field indicating type, so to speak.

    edit: as for the invalid code, i just wrote it quickly as example but you are right. Pretend it says switch (field.SomeType) instead of it being a method
