Javascript dynamically inserted later on: how to make it run?

Asked 2022-Apr-17 at 14:12

I have scripts In my React app that are inserted dynamically later on. The scripts don't load.

In my database there is a field called content, which contains data that includes html and javascript. There are many records and each record can include multiple scripts in the content field. So it's not really an option to statically specify each of the script-urls in my React app. The field for a record could for example look like:

Rendering raw HTML without React recommended method is not a good practice. React recommends method dangerouslySetInnerHTML to render raw HTML.

msvc std::lower_bound requires const operator*

...

ANSWER

Answered 2022-Mar-18 at 20:51

std::lower_bound takes a Cpp17ForwardIterator, which must also be a Cpp17InputIterator. The Cpp17InputIterator requirements include:

Expression Return type *a reference, convertible to T

Here, a is a "value of type X or const X", so MSVC is justified in requiring a const-qualified unary indirection operator; the "or" means that the code using the iterator can use either, and the author of the iterator has to support both. (Note that Cpp17InputIterator differs from Cpp17OutputIterator, where the required operation is *r = o, with r a non-const reference, X&.)

So your operator* should have const qualification, and return a reference; specifically, a reference to T or const T (this is a Cpp17ForwardIterator requirement). You can satisfy this straightforwardly with using reference = const T& and by making cur_ and cur_valid_ mutable.

The use of mutable here is entirely legitimate; since operator*() const is idempotent, it is "logically const" and the modifications to the data members are non-observable.

Setting up multi-release JAR unit tests

ANSWER

Answered 2022-Jan-04 at 16:07

To test a MRJAR the classes must be packaged as a jar, so don't use surefire with target/classes, but instead use failsafe during the verify phase. And you must run it at least twice, once per targeted Java version. I would write a unittest, that works for all Java versions, but might skip certain tests.

ANSWER

Answered 2021-Nov-03 at 12:57

According to this records are supported from Lombok version v1.18.20

@Builder on records is supported since the last release v1.18.20. Which version are you using? Note that this may also be just an IDE issue. If you are using IntelliJ, it may not be supported, yet.

Probably an IntelliJ issue ... try writing the code without IntelliJ auto-complete, see if it compiles ... if it does ... its an IntelliJ issue ... if it does not, something is wrong with your code.

This is a bug that is still present in Delphi 11 (thanks to LU RD for confirming that). You should submit a bug report to Quality Portal.

In the meantime, I think that you can work around it by making the assignment in TPage rather than TParagraph. Like this:

Recover deleted records from Snowflake if you don't remember the exact time / date

Asked 2021-Oct-14 at 13:49

I'm trying to recover some records but I don't remember the exact time or date they were deleted:

I remember that these records that were deleted all had 'nan' values in link and name columns, and the asof_date values were between July & October.

I believe they were deleted 1 day ago so I tried this (since 1440 min in a day) but nothing populates:

Unfortunately, since your data retention period is only 1 day, you will not be able to make use of time travel or fail safe.

For future reference, provided that you have Enterprise edition or above, then you can set the retention period to be up to 90 days, and then you have 7 days fail-safe protection after that.

Patterns in MATCH_RECOGNIZE work in a similar fashion to regular expressions; you want something like:
