QUESTION
I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.
Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS is the same as TEMPLATE to config django.core.context_processors.static but when I paste that code, turns in error saying django.core.context_processors.static doesn't exist.
I don't have idea why my javascript' script isn't working.
The configurations are the followings
Settings.py

Answered 2021-Jun-15 at 18:56Run ‘python manage.py collectstatic’ and try again.
The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.
Add the following as django documentation to your urls.py

I am trying to use beginMoveColumns to move a single column over in a QTableView, but it doesn't work properly in my example below. The cell selections get shuffled and column widths don't move. Moving rows using the same logic seems to work correctly. What am I doing wrong?
ANSWER
Answered 2021-Jun-15 at 20:13Turns out it was a bug, I made a bug report here: https://bugreports.qt.io/browse/QTBUG-94503
As a workaround I just clear cell selection on column move, and use this snippet to move column widths
QUESTION
I've started to create UI tests for my PyQt5 widgets using QtTest but have run into the following difficulties:
In order to speed up things, some of my widgets only perform operations when visible. As it seems that QtTest runs with invisible widgets, the corresponding tests fail.
For the same reason, I cannot test program logic that makes a subwidget visible under certain conditions.
Is there a way to make widgets visible during test? Is this good practice (e.g. w.r.t. CI test on GitHub) and is QtTest the way to go?
I have tried to use pytest with pytest-qt without success as I couldn't find a proper introduction or tutorial and I do know "Test PyQt GUIs with QTest and unittest".
Below you find a MWE consisting of a widget mwe_qt_widget.MyWidget with a combobox, a pushbutton and a label that gets updated by the other two subwidgets:

Answered 2021-Jun-15 at 17:01The problem is simple: QWidgets are hidden by default so isVisible() will return false, the solution is to invoke the show() method in init() to make it visible:

How to get the return value? Attach my code. My intention: Want to check the QListWidget and if it's empty, a message Box popup will raise and ask the option from the user. Problem: At the stage of beginning itself, a Message box popup will display, (I don't want it at the beginning stage), If the QListwidget is empty then the MessageBox popup will display as desired, and if we select "Yes" or " No" Button, Nothing will return/print in the first file. How to resolve?

Answered 2021-Jun-15 at 16:49In first it is not necessary to make the verification be done in a new class, it is also logical that you invoke func_create_newitem since as you point out that method must be invoked when the item was not found.

QUESTION
I have a generator object, that loads quite big amount of data and hogs the I/O of the system. The data is too big to fit into memory all at once, hence the use of generator. And I have a consumer that all of the CPU to process the data yielded by generator. It does not consume much of other resources. Is it possible to interleave these tasks using threads?
For example I'd guess it is possible to run the simplified code below in 11 seconds.

Answered 2021-Jun-15 at 16:02Send your data to separate processes. I used concurrent.futures because I like the simple interface.
This runs in about 11 seconds on my computer.

QUESTION
I am trying to run a simple parallel program on a SLURM cluster (4x raspberry Pi 3) but I have no success. I have been reading about it, but I just cannot get it to work. The problem is as follows:
I have a Python program named remove_duplicates_in_scraped_data.py. This program is executed on a single node (node=1xraspberry pi) and inside the program there is a multiprocessing loop section that looks something like:
...ANSWER
Answered 2021-Jun-15 at 06:17Pythons multiprocessing package is limited to shared memory parallelization. It spawns new processes that all have access to the main memory of a single machine.
You cannot simply scale out such a software onto multiple nodes. As the different machines do not have a shared memory that they can access.
To run your program on multiple nodes at once, you should have a look into MPI (Message Passing Interface). There is also a python package for that.
Depending on your task, it may also be suitable to run the program 4 times (so one job per node) and have it work on a subset of the data. It is often the simpler approach, but not always possible.

I am trying to make a popup for messages such as "Action completed" and I want a button on it to close the popup (A simple OK which quits only the popup). It also sometimes moves behind the window which is annoying. I have some code for the button but it has an issue with the geometry of the shape since the shape isn't exactly defined as it is variable through the size of font and text length.

I'm doing some scraping, but as I'm parsing approximately 4000 URL's, the website eventually detects my IP and blocks me every 20 iterations.
I've written a bunch of Sys.sleep(5) and a tryCatch so I'm not blocked too soon.
I use a VPN but I have to manually disconnect and reconnect it every now and then to change my IP. That's not a suitable solution with such a scraper supposed to run all night long.
I think rotating a proxy should do the job.

Answered 2021-Apr-07 at 15:25Interesting question. I think the first thing to note is that, as mentioned on this Github issue, rvest and xml2 use httr for the connections. As such, I'm going to introduce httr into this answer.
The following code chunk shows how to use httr to query a url using a proxy and extract the html content.
