idgen | 一个使用 golang 编写的大陆身份证生成器

The problem that you are having is that you call ItemLists on page load, which means it will only be processing an empty toDoList.

• My solution is to rename renderList to appendItem.

• Declare it at the top

• Don't pass the list id and list to the constructor instead pass it to appendItem in the clickhandler.

You have to assign your derived table to a local variable and dereference columns from it, e.g.

Since you're using HikariCP in your project, you should not create new connections manually using DriverManager:

To be frank with you, a 406 response could be returned for any reason ... or no reason at all.

According to the HTTP 1.1 specification (Section 6.5.6) it should be returned is the one of these headers is requesting output in a representation that the server cannot provide:

• Accept
• Accept-Charset
• Accept-Encoding
• Accept-Language

If the server implementation is following the spec, the response body should list the representations that it can provide. (Look at the response body to see if it is saying anything.)

What else could it be?

• It could conceivably be that the server is telling you that you need to provide an "accept" header.

• It could conceivably be that the server is giving a deliberately misleading response, because it thinks you are abusing the API.

But I'm really guessing. As I said at the beginning ... it could be anything.

My advice would be to read the API documentation carefully, and ask the people who run the server what you are doing wring.

• instead of find all and then filter in Javascript, why don't you select from the database right away?

• an alternative way I could think of is using a filter like bloom or cuckoo.the false positive rate should be low.

• load ids to redis, probably with redis bloom (https://github.com/RedisBloom/RedisBloom)

• check the new generated id with bloom filter.
• if exists => re-generate id. if not, insert. there could be false positive but the rate is low and you can handle it just the same.

pros: - no need to check again database every time. - checking with bloom filter is probably much faster than db. - scaling redis is easier than db.

cons: - need redis and redis bloom.

Try with nativeElement.click():

I think there should be some whitespaces or similar, convert both columns to list for test it:

Please check my fiddle to know how to achieve real time date updates:

You can change logic accordingly. But setting state must be follow by the method described in my fiddle.

Very basic rule of setting state for particular input is that onChange only affects to your input value when your setting state and assigned value state is same.

Hope this helps.

We can combine a valid instance and an set of invalid fields (so that every field, if copied, would cause validation failure) to get an invalid object using shapeless library.

Shapeless allows you to represent your class as a list of key-value pairs that are still strongly typed and support some high-level operations, and converting back from this representation to your original class.

In example below I'll be providing an invalid instance for each single field provided
