"scripts": {
"start": "SET NODE_ENV=staging && nodemon app",
"production": "set NODE_ENV=production && nodemon app",
"test": "echo \"Error: no test specified\" && exit 1"
},
...ANSWER
Answered 2021-Jun-16 at 03:49The likely problem is that the space character before &&
becomes part of the environment-variable values, so that the values are staging
and production
- note the trailing space - rather than staging
and production
.
The simplest way to avoid this is to remove the space before &&
(it looks awkward, but it works):

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

TL;DR: Why do I name go projects with a website in the path, and where do I initialize git within that path? ELI5, please.
I'm having a hard time understanding the fundamental purpose and use of the file/folder/repo structure and convention of projects/apps in the go language. I've seen a few posts, but they don't answer my overarching question of use/function and I just don't get it. Need ELI5 I guess.
Why are so many project's paths written as:
...ANSWER
Answered 2021-Jun-16 at 02:46Why do I name projects with a website in the path?
If your package has the exact same import path as someone else's package, then someone will have a hard time trying to use both packages in the same project because the import paths are not unique. So long as everyone uses a string equal to a URL that they effectively "own", such as your GitHub account (or actually own, such as your own domain), then these name collisions will not occur (excepting the fact that ownership of URLs may change over time).
It also makes it easier to go get
your project, since the host location is part of the import string. Every source file that uses the package also tells you where to get it from. That is a nice property to have.
Where do I initialize git?
Your project should have some root folder that contains everything in the project, and nothing outside of the project. Initialize git in this directory. It's also common to initialize your Go module here, if it's a Go project.
You may be restricted on where to put the git root by where you're trying to host the code. For example, if hosting on GitHub, all of the code you push has to go inside a repository. This means that you can put your git root in a higher directory that contains all your repositories, but there's no way (that I know of) to actually push this to the remote. Remember that your local file system is not the same as the remote host's. You may have a local folder called github.com/myname/
, but that doesn't mean that the remote end supports writing files to such a location.

I am trying to use next-firebase-auth package to manage authentication in my next js app. Before messing around, I wanted to run the example. However, I could not find proper explanation for the fields required in the .env file.
Could you please explain what should be the values of following fields in local.env

ANSWER
Answered 2021-Jun-16 at 01:31If you are using vuetify from vue-cli-plugin-vuetify
(vue add vuetify
), treeshaking and auto component import is enabled by default, by using vuetify-loader
.
If you look into the source code of vue-cli-plugin-vuetify
, it only uses vuetify-loader
if it is present in your package.json
. So removing vuetify-loader
from package.json
should disable this behavior.
QUESTION
I've got a Rails 5.2 application using ActiveStorage and S3 but I've been having intermittent timeout issues. I'm also just a bit more comfortable with shrine from another app.
I've been trying to create a rake task to just loop through all the records with ActiveStorage attachments and reupload them as Shrine attachments, but I've been having a few issues.
I've tried to do it through URL and through tempfiles, but I'm not exactly sure of the right steps to fetch the activestorage version and to get it uploaded to S3 and saved on the record as a shrine attachment.
I've tried the rake task here, but I think the method is only available on rails 6.
Any tips or suggestions?

QUESTION
I was making a simple to do app with mvc pattern and I saw an article which said you shouldn't pass the model values directly to the view, which made the project more complex than I thought (I am relatively new to programming and this is the first time I am trying out a design pattern).
But then later on I talked to someone who said that that is not true and you can send the model data directly to view, he didn't even use classes or some kind of grouping to separate the function he just put them in separate files.
I was wondering if there is a guideline that I couldn't find or we can do whatever we want as long as they are kind of separated. I would love an article or a guide to read up on as well.
...ANSWER
Answered 2021-Jun-16 at 01:01Since, I am not 100% sure the context in which you are trying to apply the MVC pattern, a good generic explanation of MVC can be found in GoF's 1995 book, Design Patterns: Elements of Reusable Object Oriented Software.
In the book, they state the following.
The Model is the application object, the View is its screen presentation, and the Controller defines the way the user interface reacts to user input.
A more robust explanation can be found from Martin Fowler where he also makes the case for a variation of Model View Controller that uses a Presentation Model.
If you are referring to Spring MVC then there is some magic that blurs the lines a bit. But in general, you have a controller that represents some screen or an encapsulated piece of functionality that the user (web requests) interact with. The controller serves up responses that are derived from the domain, usually via a Spring Service (i.e. @Service). The domain (Model) doesn't know anything about the View and the View may or may not know anything about the domain.
Given that, the View should be derived from the Model. But that's not always the case since sometimes how we present things to a screen is not the best logical way to model things in our domain - not to mention, the domain should be presentation agnostic. This leads into Fowler's argument for a Presentation Model, which is a model that belongs to the Presentation.
I call this a Presentation Model because it's a model that is really designed for and thus part of the presentation layer.
Microsoft took that idea and ran with it in a variant of MVC called MVVM (Model View ViewModel).
You can read more about that in Microsoft's documentation on ASP.Net Core.
So, back to your original question of "Should you pass the model directly to the view?" If you are using MVC then the controller is what provides the interaction. But if you're really asking, "Can you bind your view directly to the model?" If your model has all the stuff you need organized how your view needs it, then sure. And if it's simple enough, maybe that's the way to go. Otherwise, you could go with something like a Presentation Model or MVVM.

Can someone help me investigate why my Chainlink requests aren't getting fulfilled. They get fulfilled in my tests (see hardhat test etherscan events(https://kovan.etherscan.io/address/0x8Ae71A5a6c73dc87e0B9Da426c1b3B145a6F0d12#events).

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.
