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

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 simply want to surface an Exception message as a bad response in DRF.
The Exception can come from anywhere in the request. So for example, some nested function can have:
raise Exception('Something went wrong at this particular point')
And then in my view handler, i'd simply catch the Exception and raise it:

I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as

Answered 2021-Jun-15 at 18:32Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.
Try to look into a TransactionalOperator and its usage from the Java DSL's fluxTransform():
QUESTION
I have a third party .war file that I run on a Jetty server. I need to run code for logging purposes before the filters defined in the .war file's deployment descriptor run. The code needs to have access to the incoming request and the response object and to the context of the logger that runs for the app in the war.
Is there a way to do this in Jetty's xml configuration file? I don't want to touch the war file due to concerns about license.
I could override the deployment descriptor which would allow me to add custom filters but I believe these would then run after the filters in the war. I could also use a request customizer but that doesn't give me access to the response which I also need to edit.
I tried adding a handler to a HandlerCollection before the handler with the org.eclipse.jetty.webapp.WebAppContext that runs the war but it doesn't seem that I have access to the web app's logger's context...
Is there any way to do this? So before the web app's servlet executes run a piece of code that can access the incoming request and the response and the web app's context?
...ANSWER
Answered 2021-Jun-15 at 17:41Option 1:
To access the raw Request and Response at the various stages of their lifecycles, use the HttpChannel.Listener (make sure you read the javadoc/apidoc to understand what each event means).
Option 2:
To add a handler in the WebAppContext, before the Session/Security handling, but after other handlers, use WebAppContext.insertHandler(HandlerWrapper).
Option 3:
Create a web-fragment servlet jar that represents your servlet Filter, and add it to the WebAppContext.setExtraClassPath(String), which will be picked up and added to the actual webapp's startup.
Option 4:
Create a custom RequestLog implementation (that you add to Server.setRequestLog(RequestLog) that is notified once the request AND response are complete, so you can log the state of the request/log to whatever source you want.
Option 5:
Use one of the existing RequestLog implementations to log the details you desire to the console in the format you desire. (Look at the combination of CustomRequestLog and Slf4jRequestLogWriter)

So i have a 404 handler and a router file:
404 handler:
...ANSWER
Answered 2021-Jun-15 at 17:10Express regular request handlers are expected to have no more than 3 arguments as you can verify here.
And looking up Function.length:
length is a property of a function object, and indicates how many arguments the function expects, i.e. the number of formal parameters. This number excludes the rest parameter and only includes parameters before the first one with a default value.
It becomes clear why the second function works and the first one doesn't:

I'm struggling to use the Micronaut HTTPClient for multiple calls to a third-party REST service without receiving a io.micronaut.http.client.exceptions.ReadTimeoutException

...ANSWER
Answered 2021-Jun-15 at 09:51If this isn't going to throw an exception then I don't know what is going to.
This is caused by using blocking code within Netty's event loop.
The code over here is making a blocking request 20 times in a row which cause the machine to break. I don't know what data is coming from the client but I would never recommend to do it in this manner.

You'll find information like this:
A border layout lays out a container, arranging and resizing its components to fit in five regions: north, south, east, west, and center. Each region may contain no more than one component, and is identified by a corresponding constant: NORTH, SOUTH, EAST, WEST, and CENTER. When adding a component to a container with a border layout, use one of these five constants...
