Working with difficult AM/PM formats and REGEX with lubridate in R

Asked 2022-Feb-13 at 18:12

Hello guys I hope everyone is having a good one, I am trying to work with some AM/PM formats in lubridate on R but I cant seem to come up with a proper solution I hope you guys can correct meand help me out please!

I have a HUGE dataset that has date_time formats in a very rare way the format goes as follow:

First a number that represents the day, second an abbreviation of the month OR even the month fully spelled out a 12H time format and the strings " a. m." OR "p. m." or even a combination of more spaces between or missing "dots" then such as "a. m" to set an example please take a look at this vector:

React: Setting useState() hook clears out input fields?

Asked 2022-Feb-11 at 06:25

Whenever I set a state in my React app, it clears out my inputs (check box, numbers). Here's a very barebones version that illustrates the issue.

ANSWER

Answered 2022-Feb-11 at 06:25

Each time you set a state (setDummy), the component is rerendered and will reset you're inputs because they are uncontrolled. You need to make them controlled by using state hooks for those inputs.

QUESTION

Elastic Beanstalk environment is failing suddenly. Why?

Asked 2022-Jan-27 at 17:18

I am at a complete loss and really freaking out, because this project of mine was close to being done. I will give out a bounty for the answer that helps me (when I can). I am desperate, please help.

I have an Elastic Beanstalk project that has been working fine for literally months. Today, I decide to enable and disable a port listener as seen in the photo below:

I enabled port 80 and then the website stopped working. So I was like "oh crap, I will change it back". But guess what? It is still broken. The code has not changed whatsoever, but the application is now broken and I am freaking out.

I have restarted the app servers, rebuilt the environment and nothing. I can't even access the environment site by clicking Go to environment. I just see a Bad Gateway message on screen. The health status of the environment when first deployed is OK and then quickly goes to Severe.

If my code has not changed, what is the deal here? How can I find out what is going on here? All I changed was that port, by enabling and then disabling again.

I have already come across this question: Question and I am already doing this. This environment variable is on my application.properties file like this: server.port=5000 and its been like this for months and HAS ALREADY been working. So this can't be the reason that it broke today. I even tried adding it directly to the environment variables in Elastic Beanstalk console and same result, still getting 502 Bad Gateway.

I also have a path for the health-check configured and this has not changed in months.

Here are the last 100 lines from my log file after health status goes to Severe:

Okay, so I decided to just launch a new environment using the same exact configuration and code and it worked. Looks like Elastic Beanstalk environments can break and once that happens, there is no fixing it apparently.

The reason is that calling offsetWidth and scrollWidth leads to reflow. See also What forces layout/reflow.

In your case you should try to minimize or replace these before mentioned calls. A few resources which might be helpful in addition:

How can I mitigate the Log4Shell vulnerability in version 1.2 of Log4j?

Asked 2022-Jan-02 at 21:01

I've got a very old version of Solr and I've been trying to see if it is affected by the Log4Shell vulnerability that everybody is freaking out about (CVE-2021-44228).

The CVE only seems to apply to later versions, but a colleague doesn't buy it, so I'm trying to figure out the truth.

Unable to use value of variable inside nth-child selector in Javascript

Asked 2021-Dec-10 at 19:32

I'm trying to use the value of a variable inside the element selector that is p:nth-child(0), instead of a number that is 0, I want to put the value of a variable, in this case, It is i of for loop.

But It is giving an error

...

ANSWER

Answered 2021-Dec-10 at 16:18

IDK if it's the whole problem, but you are re-declaring the variables "gameSizePStatus" and "gameSizeP" in your loop. That's likely causing the "text" variable line to look for an element that doesn't exist at too high of a "i" value. This would also probably cause an error on your "gameSize" line for trying to find an empty string value. You should also do a null check before calling ".text()" so you don't throw an error when you reach an element that doesn't exist.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining

Rereading further, you have a comma in your for loop declaration instead of a semi-colon with an extra semi-colon after the "i++", and you aren't doing the loop anyway, since you assign "gameSizePStatus" to false and the loop wants it to be true. This means "gameSizeP" is empty when trying to run "$('p:nth-child('+gameSizeP+')')". Even if this doesn't error out, it would likely return undefined and throw an error on the ".text()".

Since I'm rewriting my comments as an answer, I'll also say that "gameSizePStatus" is an unnecessary variable. You can use other/better/simpler/cleaner logic to do the same thing. And you don't need to assign a value to "gameSizeP" when declaring it. This makes checking it's value easier later.

Here's my re-write of your code. I'm only including the relevant if statement for clarity.

QUESTION

Django 3.2.6: Path order in app urls.py related to 404

Asked 2021-Nov-24 at 21:24

I have multiple paths in my urls.py file for app communities. Here are the two that are causing issues.

path('posts//',communities_views.viewPostDetail,name="post_detail")

path('posts/delete_comment/',communities_views.viewDeleteComment,name="delete_comment")

For some reason, Django seems to get confused about the order of these two paths. When in the order as shown, Django recognizes that delete_comment is a path (meaning that in templates using something like communities:delete_comment does not throw an error when generating the template), but when attempting to navigate to the url, Django keeps catching the post_detail view and freaks out.

However, when I reverse the order of these two urls, everything works fine. Does order matter? If so, that is rather inconvenient for larger projects.

If any other information is needed, please let me know.

...

ANSWER

Answered 2021-Nov-24 at 21:24

A slug:…> can also match a sequence of numbers. If you thus visit posts/delete_comment/123, then Django will try to match it with the URL patterns and starts by the first one. This URL will match the posts/// pattern, since it sets username = 'delete_comment' and slug = '123'.

Since Django always fires the first URL pattern that matches, if you try to delete a comment, it will thus fire the viewPostDetail.

What you can do is specify the items in a different order:

Well, the regex you gave at the end of the answer incorrectly excludes _ and -. The same thing that allows _ and - is /[^a-z\u0000-\u007F]|[_-]/

Edit: But what you really want is: /[^\u0000-\u007F]|[a-zA-Z-_]/

Or manually exclude all the special characters you want to: /[^(0-9!?@#$%^&*()+\\=[\]{};':"|,.<>/]/
