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
...ANSWER
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 have three .snappy.parquet
files stored in an s3 bucket, I tried to use pandas.read_parquet()
but it only work when I specify one single parquet file, e.g: df = pandas.read_parquet("s3://bucketname/xxx.snappy.parquet")
, but if I don't specify the filename df = pandas.read_parquet("s3://bucketname")
, this won't work and it gave me error: Seek before start of file
.
I did a lot of reading, then I found this page
it suggests that we can use pyarrow
to read multiple parquet files, so here's what I tried:

And the argument to createCopyCommand

Hello i have this code to display an immage saved on my filesystem on broswer:
...ANSWER
Answered 2021-Jun-15 at 09:12Your code first tests that your input exists (as a File
) and is not a directory, then you go ahead and try to read it as a resource from the class path using getClass().getResourceAsStream(path)
. This is usually not what you want.
Try instead InputStream in = new FileInputStream(path);
.

environment variable has not been released yet. It is only supported by the developer/unreleased version of the docker image. It is planned that this feature will be available in Airflow 2.1.1. For more information, see: Adding extra requirements for build and runtime of the PROD image.
For the older version, you should build a new image and set this image in the docker-compose.yaml
. To do this, you need to follow a few steps.

QUESTION
I am trying to wrap my mind around C++ 20 concept and constraint by porting some of my old code.
...ANSWER
Answered 2021-Jun-13 at 19:33A concept is not a type, so it can’t appear as a container element type—neither in the type of an object (this is why you have to use std::vector
to approximate std::vector
) nor in the type for your concept ContainerOf
. Moreover, you can’t use a concept as a template argument, so you can’t have a higher-order ContainerLike
concept.
What you can do is make a Container
concept that checks only for empty
, add the constraint
QUESTION
I'm trying to validate some JSON files on VB.net. However, Whenever I run my code it gets stuck on
Dim Schema As JsonSchema = JsonSchema.Parse(SchemaString)
The Error Says
An unhandled exception of type 'Newtonsoft.Json.JsonException' occurred in Newtonsoft.Json.dll.
There is also a warning that says that JSON validation moved to its own package. So, I'm pretty sure I'm just importing the wrong packages, but I'm not sure.
I would be grateful if anyone could point me in the correct direction,
Thank you.
Here is my VB.net code
...ANSWER
Answered 2021-Jun-12 at 03:42$schema
is only valid at the root, and properties
values MUST be schemas.
You have a "$schema" : "#"
inside properties
. This means that you're trying to say that your JSON object should have a property called schema that can validate against the schema #
. But #
isn't a valid schema object, so the parse fails.
You need to remove the $schema
from your properties
.
I'd also suggest using a later draft of the schema spec (if you have control over the schema). Draft 6 is the oldest version that's compatible with the latest, 2020-12.
But for this you'll likely need to use a different validation package. There are several available. Mine is JsonSchema.Net.

TLDR: Create a CRC from every file(contentbased) in Directory.
Currently i used from Cpp20 the Filesystem Libary and tried to create a checksum for a file with "hash_value(p)". The thing is, the value does not change. Can you provide me some advice ho to accomplish a checksum, that changes when file content is changed. I would like to stay within the range of CPP libarys or what debian 10 can provide.
Now i tried this:
ANSWER
Answered 2021-Jun-12 at 16:59The thing is, the value does not change.
It's not supposed to. The filesystem::hash_value
is a hash of the path to the file, not the contents of the file. If you want to compute a CRC of the contents of a file, you're going to have to read those contents and apply a CRC algorithm to them.
