kandi X-RAY | krush Summary
Krush is a lightweight persistence layer for Kotlin based on Exposed SQL DSL. It’s similar to Requery and Micronaut-data jdbc, but designed to work idiomatically with Kotlin and immutable data classes. It’s based on a compile-time JPA annotation processor that generates Exposed DSL table and objects mappings for you. This lets you instantly start writing type-safe SQL queries without need to write boilerplate infrastructure code.

QUESTION
I am using MongoDB, mongoose, ejs and NodeJS for my site. I have a update password function which is not working properly. I have checked again and again by login different things in console and there is no problem in getting data in req. So I guess my problem is in the controller. This is my controller:
...ANSWER
Answered 2021-Mar-07 at 06:32It seems that the problem is that the return res.redirect('/profile');
command is executed before your callback functions. Which is normal since this is how the event loop works.
Try to remove the return res.redirect('/profile');
line to see if the error goes away. Callbacks at node.js execute at a later stage of the event loop.
Generally I would recommend to refactor your code to use promises instead of callbacks since that causes the "callback hell" anti-pattern.
If you refactor your code to use promises, then you will be able to use .then or async await, which will help you write cleaner code and help you spot any error easily.
QUESTION
I wrote a custom context provider in the below which holds application settings as a Context
as well as save it in localStorage
(thanks to a post by Alex Krush).
I added initialized
flag to avoid saving the value fetched from localStorage
right after the component is mounted (useEffect
will be run at the timing of componentDidMount
and try to write the fetched value to the storage).
ANSWER
Answered 2020-May-31 at 10:35I would probably add some sort of test to see what happens in every possible scenario.
However, this is my theory: In step 5, window 1 will not try to run localStorage.setItem (as you said), since initialized was just set to false. It will instead set initialized to true. Step 6 should therefore work as expected, and this shouldn't be an issue.
