QUESTION

save_kable() in R does not compile LaTeX table

Asked 2022-Mar-20 at 00:14

I'm working on a convenience function in R that prints a publication quality LaTeX table from some common model objects. It all works just great for me on my Mac, but I've built it largely for a colleague who's on a PC, for whom the file writing fails when calling save_kable() from the kableExtra package.

We get no output whatsoever from this. No pdf and no error messages.

A simple reproducible example, which fails in the same way, is as follows:

...

ANSWER

Answered 2022-Mar-20 at 00:14

The problem turned out to be missing LaTeX dependencies. The kableExtra package creates a .tex file with a long list of required packages (see below), but MikTex, the Tex distribution we were using, was unable to automatically install them, and the errors didn't propagate through to R. Here is a post with some useful details.

There are a number of solutions, each for a different distribution.

Use TexLive, rather than MikTex. I use TexLive on my Mac, and it appears to have no trouble locating and installing the dependencies. The downside is that it's gigantic (>7GB to MikTex's <1GB).
For MikTex, you can get the packages downloaded with a combination of two approaches. First, set keep_tex = TRUE in kableExtra::save_kable(), which should produce the .tex file for compilation. Next, compile it at the command line with xelatex yourtable.tex. You can't use latex yourtable.tex, since this compiler can't work with the required fontspec package. This may download all that you need. If it doesn't, check the log file for a missing .sty file: we needed to manually download the tabu package. You can manually install the missing files from MikTex Console: Packages > Search for "tabu" > "+" to install. Rinse, repeat until you have all the packages you need. You could do this for all the dependencies, but there are a lot, so might as well let the compiler do as much work as possible first, then backfill as needed.
Compile with TinyTex in R. Create the .tex file as above (`keep_tex = TRUE'). Then:

How to get the most liked users on a particular date in django

Asked 2021-Mar-28 at 22:09

So I have a social media app, where users can like the posts of other users. Now I fetch the top 20 users who have received the most number of likes. Everything is perfect. But the problem is I cant figure out , how I can fetch the top users who have received the most likes on a particular date, for example get the top users who received most likes only today

My LIKES MODEL

ANSWER

Answered 2021-Mar-28 at 22:09

Q(author__likes__liked_on = datetime.today()) won't work, because liked_on is a datetime, while datetime.today() is a date. And the filtered field is on the 'through' table.

So you need to cast liked_on to a date, and look up the field on postlike (lower-cased by default):

Q(author__postlike__liked_on__date = datetime.today()))

First I changed the user attribute in your Post model, I added related_name because otherwise the related names were clashing. This is the definition I used, otherwise your models are unchanged.

QUESTION

How to work around maximum execution time when uploading to S3 Bucket?

Asked 2020-Aug-16 at 00:22

I am using the S3-for-Google-Apps-Script library to export full attachments from Gmail to an S3 bucket. I changed the S3 code to upload the actual content of the attachment rather than an encoded string, as detailed in this post.

However, when attempting to upload an attachment approximately > 5 MB, apps script throws the following error: "Maximum Execution Time Exceeded". I used timestamps to measure the difference in time to ensure that the time issue occurred in the s3.putObject(bucket,objectKey,file) function.

It might be also helpful to note that for a file barely over the limit, it still gets uploaded to my s3 bucket, but apps script returns that the execution time has been exceeded (30 seconds) to the user, disrupting user flow.

Reproducible Example

This is basically a simple button that scrapes a current email for all attachments, if they are pdf's then it calls the export function. and it exports those attachments to our s3 instance. the problem is that when the file > 5mb, it throws the error:

"exportHandler exceeded execution time"

If you're trying to reproduce this be aware that you need to copy an instance of s3 for gas and initialize that as a separate library in apps script with the changes made here.

In order to link the libraries, go to file>libraries, and add the respective library id, version, and development mode in the google apps script console. You'll also need to save your AWS access key and secret key in your property service cache, as detailed in the library documentation.

Regarding the first question

From https://developers.google.com/gsuite/add-ons/concepts/actions#callback_functions

Warning: The Apps Script Card service limits callback functions to a maximum of 30 seconds of execution time. If the execution takes longer than that, your add-on UI may not update its card display properly in response to the Action.

Regarding the second question

On the answer to Google Apps Script Async function execution on Server side it's suggested a "hack": Use an "open link" action to call something that can run asynchronously the task that will requiere a long time to run.

Answer to rev 1.

Regarding the first question

In Google Apps Script, a custom function is a function to be used in a Google Sheets formula. There is no way not extend this limit. Reference https://developers.google.com/app-script/guides/sheets/functions

onOpen and onEdit simple triggers has also a 30 seconds execution time limit. Reference https://developers.google.com/apps-script/guides/triggers

Functions being executed from the Google Apps Script editor, a custom menu, an image that has assigned the function, installable triggers, client side code, Google Apps Script API has an execution time limit of 6 minutes for regular Google accounts (like those that have a @gmail.com email address) by the other hand G Suite accounts have a 30 minutes limit.
