You can't do this from command level. But I guess you could write container_commands script to rename your docker-compose file from docker-compose.dev.yml to docker-compose.yml:

You can use the container_commands key to execute commands that affect your application source code. Container commands run after the application and web server have been set up and the application version archive has been extracted, but before the application version is deployed.

I tried to replicate the issue using simplified setup with just docker-compose.prod.yml and Docker running on 64bit Amazon Linux 2 3.4.1 EB platform.

QUESTION

Confused about the Visitor Design Pattern

Asked 2021-Jun-11 at 00:43

So, I was just reading about the Visitor pattern and I found the back and forth between the Visitor and the Elements very strange!

Basically we call the element, we pass it a visitor and then the element passes itself to the visitor. AND THEN the visitor operates the element. What? Why? It feels so unnecessary. I call it the "back and forth madness".

So, the intention of the Visitor is to decouple the Elements from their actions when the same actions need to be implemented across all the elements. This is done in case we need to extend our Elements with new actions, we don't want to go into all those classes and modify code that is already stable. So we're following the Open/Closed principle here.

Why is there all this back-and-forth and what do we lose if we don't have this?

For example, I made this code that keeps that purpose in mind but skips the interaction madness of the visitor pattern. Basically I have Animals that jump and eat. I wanted to decouple those actions from the objects, so I move the actions to Visitors. Eating and jumping increases the animal health (I know, this is a very silly example...)

ANSWER

Answered 2021-Jun-03 at 17:21

The code in the OP resembles a well-known variation of the Visitor design pattern known as an Internal Visitor (see e.g. Extensibility for the Masses. Practical Extensibility with Object Algebras by Bruno C. d. S. Oliveira and William R. Cook). That variation, however, uses generics and return values (instead of void) to solve some of the problems that the Visitor pattern addresses.

Which problem is that, and why is the OP variation probably insufficient?

The main problem addressed by the Visitor pattern is when you have heterogenous objects that you need to treat the same. As the Gang of Four, (the authors of Design Patterns) states, you use the pattern when

"an object structure contains many classes of objects with differing interfaces, and you want to perform operations on these objects that depend on their concrete classes."

What's missing from this sentence is that while you'd like to "perform operations on these objects that depend on their concrete classes", you want to treat those concrete classes as though they have a single polymorphic type.

A period example

Using the animal domain is rarely illustrative (I'll get back to that later), so here's another more realistic example. Examples are in C# - I hope they're still useful to you.

Imagine that you're developing an online restaurant reservation system. As part of that system, you need to be able to show a calendar to users. This calendar could display how many remaining seats are available on a given day, or list all reservations on the day.

Sometimes, you want to display a single day, but at other times, you want to display an entire month as a single calendar object. Throw in an entire year for good measure. This means that you have three periods: year, month, and day. Each has differing interfaces:

It's not flattening it per se. But the scale of the second line/plot is much bigger than the first that it shows like it's flattened.

You will need to use multiple scales (multiple y axis).

Check out this example from the matplotlib documentation.

Basically, you will need to do something like this:

QUESTION

Countif True/False values for alternating rows

Asked 2021-Apr-25 at 16:56

How can I automate my scoring formula to count odd rows as 1 for TRUE and even rows as 1 for FALSE?

Backstory

I'm trying to import a quiz that I found in the back of an ancient, eldritch tome into G Sheets. The order of the questions is fixed - the notes in the margins are very specific that a "dire fate" awaits anyone who "dares disturb these ancient mysteries." So I'm putting the questions in G Sheets in order, but in order to count the scores, I need to have every odd row give +1 if the answer is TRUE and every even row give +1 if the answer is FALSE.

Row Number Question Answer Score 1 Dread Cthulhu is my personal Lord and Slayer TRUE 1 2 Men are destined to master their own fates FALSE 1 3 This way is madness TRUE 0 4 These secrets should have stayed buried FALSE 0

I know I could brute force this with addition, such as

=COUNTIF(C2,TRUE)+COUNTIF(C4,TRUE)+COUNTIF(C6,TRUE)...

but every minute I spend typing, I feel the tendrils of existential dread gnawing at the foundations of my soul. Plus, that sounds super-boring.

So, is there a way to automate having COUNTIF() (or COUNTIFS()) do this for me?

Things That I Have Tried or Thought About

ROW(), but it doesn't seem to play nice with COUNTIFS(), just gives me a 0.

=COUNTIFS(C2:C666,TRUE,A2:A666,ISEVEN(ROW)

Adding a cheater-column that does this for me with ROW(), but I'm worried that tinkering with the table will unleash untold horrors on our world.
Maybe something with DCOUNT or ARRAYFORMULA? But those seem to me MORE forbidden than the Necronomicon, not less.

Did try this, but it's just giving me the total number of true values:

=ARRAYFORMULA(COUNTIFS(A3:A24,ISEVEN(ROW()),A3:A24,TRUE))

What else y'all got?

QUESTION

React Table v7 not populating with data when using useState within the component

Asked 2021-Apr-18 at 14:57

Edit: final solution at the bottom.

I am trying to build a simple web-app to display some data stored in firestore database, using React Table v7. I'm pretty new to React and javascript in general so forgive me if I use the wrong terminology.

At first I had put the function to fetch data inside App.jsx, passing it to state with setState within a useEffect hook, and it was working without an issue.

Then a colleague suggested that it is a good practice passing data to a component state instead of the app state, and that's where problems started to arise.

As of now, I cannot manage to populate the table. The header gets rendered but there's nothing else, and the only way I can make it show data is to make a small change in Table.jsx while npm start is running (such as adding or changing the output of any console.log) and saving the file. Only then, data is displayed.

I've been trying everything I could think of for about 2 days now (last thing I tried was wrapping Table.jsx into another component, but nothing changed).

I tried console.loging all the steps where data is involved to try and debug this, but I'm failing to understand where the problem is. Here's the output when the app loads first:

My code currently:

In your TableContainer, you initialize data with an empty array. That's being sent along to Table until you finish getting data from your server. If you don't want that to happen, you should change your default (in useState) to something like false and explicitly handle that case (e.g. display "Please wait. Loading" if data === false).

The default 'List' constructor isn't available when null safety is enabled. Try using a list literal, 'List.filled' or 'List.generate'.dartdefault_list_constructor 'List' is deprecated and shouldn't be used. Use a list literal, [], or the List.filled constructor instead.

Raku makes it very easy to support existing functions on my new types by implementing [multi?|sub?] methods on my type. However, I'm wondering if it also provides a way to have existing (or new) methods apply to Lists or other positional collections of my type (without augmenting List, which is the first step on the path to madness…).
