QUESTION
I am building an app following the Rest Countries API challenge from frontendmentor (https://www.frontendmentor.io/challenges/rest-countries-api-with-color-theme-switcher-5cacc469fec04111f7b848ca). I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.
CountryDetails.js
...ANSWER
Answered 2021-Jun-15 at 17:07The issue seems to be that you are already on the "/country/:name"
path and are clicking to visit another country. The router correctly updates the URL in the address bar, but because CountryDetail
is already mounted it neglects to recompute the item
and allCountries
state. This is because the useEffect
hook only runs once when the component mounts.
The name
param (match.params.name
) is actually a dependency for the GET requests, it should be added to the useEffect
hook's dependency array.

I am trying to find the highest scoring fulltext query from two nodes:
...ANSWER
Answered 2021-Jun-07 at 20:28We can use the results of the first search to boost the score of the second, based on which movie node the actor node acted in.
You haven't told us what you want to do with the scores mathematically, so for this example I'll just add them.

This is one of the text(phone in this case) example which I need to get out of there:
608910536
Here is the example of email in html:
...ANSWER
Answered 2021-May-26 at 21:03I looked at your HTML and it seems that there is only one specific url that comes with your number (http://monitoring.octopuspro.cz/List.aspx?phone=). A fast prototyping approach is to grep for this and its following numbers. I made a fast check on regex101 so you can check out there too and maybe play a little bit with until you understand it: https://regex101.com/r/hTpTdy/1 After you understand it, you have to use regex in your code and fetch the numbers (in this case its the \w from the regex) with your preferred regex library and you're done.
TLDR; for a fast solution and specific to this case use this regex http://monitoring.octopuspro.cz/List.aspx?phone=\w*

QUESTION
Is there any known danger with exposing the use of a FullText index to internal and possibly public users?
Assuming the queries are properly parameterized, is there any way that a user could abuse the inputs to trigger a SQL injection or denial of service attack?
...ANSWER
Answered 2021-May-24 at 19:38When talking about SQL injection the risk is that someone can introduce SQL keywords into the query itself by adding SQL to a data parameter.
This is why separation of data and query is absolutely critical. This normally plays out by using placeholder values, as in:
QUESTION
I am trying to do reranking Queries today.
My features.json looks like this:
...ANSWER
Answered 2021-May-23 at 12:04I think the error comes from rord()
expecting only a fieldname as argument.
You don't need to scale the values before using rord() or ord(), scaling won't affect their lexicographic order so each value index will remain the same as without scaling.
In other words "{!func}recip(rord(textLength), 1,1000,1000)"
should be fine.
QUESTION
I built a website with laravel 8. The server is a 6 cores CPU / 6 GB Ram VPS. Server is Linux CentOS with nginx and mysql 8.
At peak period, there is about 500 visits online simultaneously. The CPU become 100% during the peak period and >80% in rest of the time.
I checked the usage and found most resource is used by mysql. Then I located some slow queries and I think this many-to-many relationship query is one of the main cause.
There is a Video model and Genre model with many-to-many relationship setup. In the video table, there is about 800,000 rows. There is 700+ genres in genre table and there is 237,4344 relationships in genre_video
table. videos.id
and genres.id
are primary index of videos
and genres
table respectively. foreign keys are set up in genre_video
Video model
...ANSWER
Answered 2021-May-21 at 05:17Many:to:many tables tend to be poorly indexed, leading to lots of extra CPU. This shows the optimal schema (no auto_inc) and indexing (2 composite indexes):
