How to Config Javascript ' script in Django?

Asked 2021-Jun-16 at 02:47

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

Run ‘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

QUESTION

How strict is the mvc pattern with model and view interactions?

Asked 2021-Jun-16 at 01:01

I am confused about how model and view can interact

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.

Since, 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.

How to make an axios get request on page load, then render a am4chart with that data?

Asked 2021-Jun-15 at 22:40

I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.

I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.

Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

How to make background images load faster

Asked 2021-Jun-15 at 22:23

Most of my WordPress websites have a background image in the top fold. These images are the Largest Contentful Paint Element on the page and usually they get loaded last. Somewhere I read that 'Background images are last in line to be grabbed when a page is loaded'. Is it true?
Is it a good idea to use a place holder or image in the place of the background image and then change it later so that the LCP gets loaded quickly like below.

ANSWER

Answered 2021-May-14 at 01:42

You don't want to use a placeholder image to prioritize your background images in situations like this, you want to use . That will tell the browser to start downloading the image as soon as possible.

Try adding the following code to the of your page, and then use your background image as normal. It should load much faster:

Surprisingly, this is not undefined behavior.

Static initialization [basic.start.static]

Constant initialization is performed if a variable or temporary object with static or thread storage duration is constant-initialized. If constant initialization is not performed, a variable with static storage duration or thread storage duration is zero-initialized. Together, zero-initialization and constant initialization are called static initialization; all other initialization is dynamic initialization. All static initialization strongly happens before any dynamic initialization.

Important parts bold-faced. "Static initialization" includes global variable initialization, "static storage duration" includes global variables, and the above clause is applicable here:

Yes, React refs need to be forwarded when using functional components.
You can't use the useRef hook within the loop.

Managing nested Firebase realtime DB queries with await/async

Asked 2021-Jun-15 at 19:34

I'm writing a Firebase function (Gist) which

Queries a realtime database ref (events) in the following fashion:

await admin.database().ref('/events_geo').once('value').then(snapshots => {
Iterates through all the events

snapshots.forEach(snapshot => {
Events are filtered by a criteria for further processing
Several queries are fired off towards realtime DB to get details related to the event

await database().ref("/ratings").orderByChild('fk_event').equalTo(snapshot.key).once('value').then(snapshots => {
Data is prepared for SendGrid and the processing is finished

All of the data processing works perfectly fine but I can't get the outer await (point 1 in my list) to wait for the inner awaits (queries towards realtime DB) and thus when SendGrid should be called the data is empty. The data arrives a little while later. Example output from Firebase function logs can be seen below:

10:54:12.642 AM Function execution started

10:54:13.945 AM There are no emails to be sent in afterEventHostMailGoodRating

10:54:14.048 AM There are no emails to be sent in afterEventHostMailBadRating

10:54:14.052 AM Function execution took 1412 ms, finished with status: 'ok'

10:54:14.148 AM

Super hyggelig aften :)

super oplevelse, ... long string generated

Gist showing the function in question

I'm probably mixing up my async/awaits because of the awaits inside the await. But I don't see how else the code could be written without splitting it out into many atomic pieces but that would still require stitching a bunch of awaits together and make it harder to read.

So, two questions in total. Can this code work and what would be the ideal way to handle this pattern of making further processing on top of data fetched from Realtime DB?

Validate list of last names of Hotel Guests according to the corresponding first name in a text file in Python

Asked 2021-Jun-15 at 19:30

I have a text file called listofhotelguests.txt where hotelguests are stored line by line with their first names separated by && as a delimiter. Can someone explain how I can have my Python program read it so it associates john with doe, ronald with macdonald, and george with washington?

My expected outcome I'm hoping for is if I prompt the user for their lastname to make sure their a valid guest on the list, the program will check it against what it has in the file for whatever the firstname they entered earlier was.

So if someone enters george as their first name, the program retrieves the line where it has george&&washington, prompts the user to enter their lastname and if it doesn't match what it has, either say it matches or doesn't. I can figure the rest out later myself.

Assuming there is nobody with the same names.

I know I have to split the lines with &&, and somehow store what's before && as something like name1 and whats after && as name2? Or could I do something where if the firstname and lastname are on the same line it returns name1 and password1?

Not sure on what to do. Python is one of my newer languages, and I'm the only CS student in my family and friend groups, so I couldn't ask anybody else for help. Got nowhere by myself.

Even just pointing me in the direction of what I need to study would help immensely.

QUESTION

Is There a Way to Cause Powershell to Use a Particular Format for a Function's Output?

Asked 2021-Jun-15 at 18:42

I wish to suggest (perhaps enforce, but I am not firm on the semantics yet) a particular format for the output of a PowerShell function.

about_Format.ps1xml (versioned for PowerShell 7.1) says this: 'Beginning in PowerShell 6, the default views are defined in PowerShell source code. The Format.ps1xml files from PowerShell 5.1 and earlier versions don't exist in PowerShell 6 and later versions.'. The article then goes on to explain how Format.ps1xml files can be used to change the display of objects, etc etc. This is not very explicit: 'don't exist' -ne 'cannot exist'...

This begs several questions:

Although they 'don't exist', can Format.ps1xml files be created/used in versions of PowerShell greater than 5.1?
Whether they can or not, is there some better practice for suggesting to PowerShell how a certain function should format returned data? Note that inherent in 'suggest' is that the pipeline nature of PowerShell's output must be preserved: the user must still be able to pipe the output of the function to Format-List or ForEach-Object etc..

For example, the Get-ADUser cmdlet returns objects formatted by Format-List. If I write a function called Search-ADUser that calls Get-ADUser internally and returns some of those objects, the output will also be formatted as a list. Piping the output to Format-Table before returning it does not satisfy my requirements, because the output will then not be treated as separate objects in a pipeline.

Example code:

Although they 'don't exist', can Format.ps1xml files be created/used in versions of PowerShell greater than 5.1?

Yes; in fact any third-party code must use them to define custom formatting.
- That *.ps1xml files are invariably needed for such definitions is unfortunate; GitHub issue #7845 asks for an in-memory, API-based alternative (which for type data already exists, via the Update-TypeData cmdlet).
It is only the formatting data that ships with PowerShell that is now hardcoded into the PowerShell (Core) executable, presumably for performance reasons.

is there some better practice for suggesting to PowerShell how a certain function should format returned data?

The lack of an API-based way to define formatting data requires the following approach:

Determine the full name of the .NET type(s) to which the formatting should apply.
- If it is [pscustomobject] instances that the formatting should apply to, you need to (a) choose a unique (virtual) type name and (b) assign it to the [pscustomobject] instances via PowerShell's ETS (Extended Type System); e.g.:
  - For [pscustomobject] instances created by the Select-Object cmdlet:
