Use .find instead, and let TypeScript infer the type automatically, which will be PlayerType | undefined.

In this case, the record shown is not a duplicate because the city differs from ID 5 and ID 6.

But you could probably do row_number function and partition by email and date created.

QUESTION

Some types could not be loaded from a dll that was compiled from a local project

Asked 2021-May-01 at 11:11

Setup

I am working on a C# project without external dependencies, named "Hopper". I have split it up into a couple of different modules, each contained within a corresponding sub-folder. The relevant ones for the problem are the following:

Utils/Hopper.Utils.csproj
Shared/Hopper.Shared.csproj
Core/Hopper.Core.csproj, which references Utils and Shared, more details later
Mine/Hopper.Mine.csproj, which references Core

All of these target .NET 4.8, including Hopper.Core.

I have set the AssemblyName property for each of the projects to the corresponding string. For example, the Hopper.Utils.csproj:

Found out the reason. There is a bug in the CLR type system that has been around for 6 years. Basically, fields (either static or non-static) of type of a generic struct declared in other structs cause this behavior. See this github thread for more details.

In my case, I have been able to make a shorter version that illustrates the bug.

The compiler should have generated a warning, "Expression with possibly no effect" (or similar), for every line in your constructor. Read the warnings - they're useful.

Using props.children and styled-component "as" prop with typescript

I've looked through several existing solutions and posts and couldn't really find any solution.

So, I'm using React with Typescript and styled-component.

Here is the simplified Codesandbox Code of it

Typescript template literal types are not as smart as you might think. You might expect h${props.level} to evaluate to a union type "h1" | "h2" | ... based on the type of your props.level variable. Instead it is just string. So you will need an as assertion somewhere in your code in order to declare that this string is a valid key of JSX.IntrinsicElements.

Getting the union "h1" | "h2" | ... as a type is tough because Props['level'] is a union of number literals rather than string literals. But we don't really need the union because t doesn't really matter which heading type it is. You can use as "h1" and you'll be fine.

Add class to HTML rows with jQuery plugin?

Asked 2021-Mar-24 at 11:54

I have this table in HTML that I need to modify by using jQuery specifically. I need to apply 'header' class to main row and 'even' and 'odd' classes to the other rows in consecutive order.

As a result, the table will have a blue main header and light grey background row in each consecutive row. How can I achieve this? I have CSS already, just need to figure out how to grab these row and add the classes. You can see my attempts in attached .js file. What am I doing wrong?

Issue with z-index and transform

Asked 2021-Mar-15 at 22:40

I am trying to create a dropdown menu with secondary and tertiary sub menus. The sub menus are supposed to slide out from underneath the parent menus. The actual code has several divs nested in multiple levels.

I have added a transform of translateY(700px) to the secondary-menu element to make it slide from underneath the primary-menu. However that causes the tertiary-menu to slide over the secondary-menu and not underneath it.

If the transform is removed the tertiary-menu works fine. A z-index of -1 was provided on tertiary-menu but that does not help. I have tried other combination of z-index on secondary and tertiary menus but it does not work.

There are quite a few related questions on this site but they don't help in my case. Here is the stripped down version of code to recreate the issue:

...

ANSWER

Answered 2021-Mar-15 at 07:48

The 'z-index' you put in the '.tertiary-menu' is working.

The reason it doesn't seem to work is because '.tertiary-menu' is a children of '.category'.

The background of '.category' is transparent, so the '.tertiary-menu' below is visible.

Simply add the background color and height to '.category' and it will look like this.

ANSWER

Answered 2021-Mar-04 at 17:22

There are 2 ways I can think of

1: Summon an invisible armorstand with the item as a passenger. This might cause hoppers to not pick it up (havent tested), just remember to kill the armorstand and item when removing them.

2: Summon an invisible armorstand with the item on its head. Hoppers/minecarts cannot pick it up, but it will not rotate and bob. This is the easier method, but it wont look like an actual item. If you wanted, you could have the armorstands tp @s ~ ~ ~ ~1 ~ to make them rotate.
