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

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

How do I check user input against multiple lists python?
Ex. I want to check if an input is in one of four lists. One list for up down left and right. Each list has the different acceptable ways to make the program continue. Once the input is verified to be in one of the lists i will need to figure out how to make it check against the individual lists so that the input correlates correctly to the desired direction.
Custom characters are used in two spots but they print properly.

QUESTION
State of the application:
- A single virtual machine which runs an apache server.
- Application exposed via the virtual machine's public IP (not behind a loadbalancer)
I have an healthprobe endpoint running that needs probed every few seconds to see if the app is up, and trigger an alert in case it is not.
What are my options? I want to get the healthprobe up and running first, before I move to a virtual machine scale set and a load balancer.
...ANSWER
Answered 2021-Jun-16 at 00:05Under Support+troubleshooting -> Resource health of your virtual machine portal panel, you can set up a health alert. You can then select under which conditions the alert should be triggered. In your case, Current resource status: Unavailable should work just fine. You can also implement a custom notification (E-Mail) under Actions or implement a logic that triggers an Azure Function or Logic App that performs an action when the VM is unavailable.
To detect if your application in Apache server is working correctly you can use a monitoring solution that checks the Apache error logs.

In part of my application I have an option that displays a list of albums by the current artist that aren't in the music library. To get this I call a music API to get the list of all albums by that artist and then I remove the albums that are in the current library.
To cope with the different casing of names and the possibility of missing (or extra punctuation) in the title I have written an IEqualityComparer
to use in the .Except
call:

Answered 2021-Jun-15 at 23:05If you're going to use the CompareOptions
enum, I feel like you might as well use it with the CompareInfo
class that it's documented as being designed for:
Defines the string comparison options to use with CompareInfo.
Then you can just use the GetHashCode(string, CompareOptions)
method from that class (and even the Compare(string, string, CompareOptions)
method if you like).

I am working on a test which runs into a dropdown with invalid selections. The dropdown does not disable these, you can click them, they simply read "unavailable" for the product.
...ANSWER
Answered 2021-Jun-15 at 16:25You can do something like this: You loop through the options fields in your drop down using each()
. Now check for the inner text for each of the options using text()
jquery method. Once you find the element, use cy.select()
to select the element.

QUESTION
Context
Since Windows 10 version 2004 update, the Magnifier windows application was updated. And as with every update, there are some issues with it.
Since those issues might take a long time to fix, I've decided to implement my own small project full screen magnifier.
I've been developing in c#, .Net 4.6 using the Magnification API from windows magnification.dll . All went good and well, and the main functionality is now implemented. One thing is missing though, a smoothing Mode for pixelated content... Windows Magnifier implements an anti aliasing/ smoothing to the Zoomed in content.
I've checked and the Magnification API, doesn't seem to provide that option.
how do i add smoothing mode to magnifier on windows magnification API?
I'm aware of pixel smoothing methods, but not familiar with win32 API to know where to hook the smoothing method to, before the screen refreshes.
EDIT:
Thanks to @IInspectable answer, after a small search i found this call to the Magnification API in a python project.
Based on that, I wrote this snippet in my C# application , and it works as intended!
...ANSWER
Answered 2021-Jun-15 at 17:03There is no public interface in the Magnification API that allows clients to apply filtering (other than color transforms). This used to be possible, but the MagSetImageScalingCallback API was deprecated in Windows 7:
This function works only when Desktop Window Manager (DWM) is off.
Even if it is still available, it will no longer work as designed. From Desktop Window Manager is always on:
In Windows 8, Desktop Window Manager (DWM) is always ON and cannot be disabled by end users and apps.
With that, you're pretty much out of luck trying to replicate the results of the Magnifier application's upscaler using the Magnification API.
The Magnifier application appears to be using undocumented API calls to accomplish the upscaling effects. Running dumpbin /IMPORTS magnify.exe | findstr "Mag"
lists some of the public APIs, as well as the following:
MagSetLensUseBitmapSmoothing
MagSetFullscreenUseBitmapSmoothing
Unless you are willing to reverse-engineer those API calls, you're going to have to spend your time on another project, or look into a different solution.
A note on the upscaling algorithm: If you look closely you'll notice that the upscaled image doesn't exhibit any of the artifacts associated with smoothing algorithms.
The image isn't blurred in any way. Instead, it shows sharp edges everywhere. I don't know what upscaling algorithm is at work here. Wikipedia's entry on Pixel-art scaling algorithms lists some that have very similar properties. It might well be one of those, or a modified version thereof.
