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.

QUESTION

How to type-constrain the entries of a Raku function's array argument?

Asked 2021-Jun-15 at 23:08

I am trying to define a subroutine in Raku whose argument is, say, an Array of Ints (imposing that as a constraint, i.e. rejecting arguments that are not Arrays of Ints).

Question: What is the "best" (most idiomatic, or straightforward, or whatever you think 'best' should mean here) way to achieve that?

Examples run in the Raku REPL follow.

ANSWER

Answered 2021-Jun-15 at 06:40

I think the main misunderstanding is that my Int @a = 1,2,3 and [1,2,3] are somehow equivalent. They are not. The first case defines an array that will only take Int values. The second case defines an array that will take anything, and just happens to have Int values in it.

I'll try to cover all versions you tried, why they didn't work, and possibly how it would work. I'll be using a bare dd as proof that the body of the function was reached.

Can I free mallocs that are being generated in every step of a recursion in C?

Asked 2021-Jun-15 at 20:53

I am making a simulation with C (for perfomance) that (currently) uses recursion and mallocs (generated in every step of the recursion). The problem is that I am not being able to free the mallocs anywhere in the code, without having the wrong final output. The code consist of two functions and the main function:

evolution(double initial_energy)

ANSWER

Answered 2021-Jun-13 at 04:47

You're supposed to free memory right after the last time it will be used. In your program, after the while loop in recursion, Energy isn't used again, so you should free it right after that (i.e., right before return event_counter;).

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.

When you're stuck on a problem, it never hurts to go back and consult the documentation.

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...

Apparently all you have to do is to close out the file. It seems to only show when the file is opened.

Perhaps a later version of Visual Studio can make this warning behave more consistently with a standard warning in VS. Really it behaves very much like a refactoring / code cleanup suggestion (which commonly has a grey, squiggly line), rather than an actual warning. It's like it's just been mislabeled in development or whatever. However the good thing is that as long as the file is closed, it doesn't pollute the build or the errors window with warning messages.

UML class diagram for domain with movies

Asked 2021-Jun-15 at 11:58

I am currently creating class diagrams in UML for a movie test domain. I would like to know if I am doing it right. Well, I have two alternatives (the first version in the first picture, the second in the second - I think the first one is better). I'm wondering if I've established the so-called "relationship owner" correctly, that is, from which class to which direction the relationships go. I also don't know if I didn't get multiplicity wrong (one to one, one to many etc.).

So on my domain I would like to have movies of course, the actors starring in those movies and directors. I wonder if the class name "Character" is good in this case, because I mean all the characters that take part in a movie - it can be director, actor but also for example "Batman". Maybe I should make a distinction here between "Movie Character" and then "Human", "Monster", whatever. But I don't know how to do it elegantly, will I then inherit from the Character class? I'm also wondering if I shouldn't put classes like City or Country together in one class called Address - but I wanted the classes to take attributes like in this case, that one is Master and the other is detail - and the relationship set in the right direction. I use only relations such as Inheritance and Dependency, I do not know if I should change something in this case.

Version 1

Version 2

Thanks in advance for any suggestions or advice!

In short

Use inheritance very carefully. Prefer association over inheritance whenever your inheritance is not a permanent truth from the birth to the death of an object. ANd keep in mind that dependencies between classes do not make any promises about objects of those classes.

Some more explanations

Some clarifications on the UML syntax:

I understand that your plain thick lines ended with a small hollow triangle represent a specialization/generalization relationship (aka inheritance). If this is correct, the triangle should be larger to avoid visual confusion. Moreover multiplicity makes no sense with inheritance and should be removed.
I understand that with the dotted line you intend to represent an association with multiplicity. If this is correct:
- the association should be plain lines, because dotted lines are for dependencies, and multiplicity would make no sense.
- the meaning you give to the arrow head would be unclear. Do you use them to document navigability? In case of doubt, remove them. If you want to document ownership of the association end, use the dot notation instead. (we cannot say if it’s right or wrong, since it’s a decision on how your model sees the associations)

In view of your comments and the third model linked therein, there are some key UML semantics you need to keep in mind:

Inheritance is an ultra-strong relationship which means "is (always) a". In your example, you may say that an Actor is always a Person, and hence, everything you say about a Person is also true for an Actor. By the way, you should avoid repeating inherited properties or methods, since it could create some ambiguity.
Inheritance is not a substitute for aggregation, composition or association. You can for example not say that a CrewMember (one person) is always a Crew (a group of persons). A CrewMember belongs to a Crew but there are things that the crew can do together that the individual member can't.
Inheritance is not suitable if it's not always true. A Character for example may often be a Person. But not always;: you can have ghost characters, comic characters, robot characters, or animals.
Association means that there is some structural relation between some instances of the associated classes. For example, that one ore several persons live in one city, seems a very relevant assocaition.
Dependency means that a class is dependent on another, i.e. without the other class it would not work or something would be missing. It's a statement about the classes and not the objects. I.e. If you meant to say that Person is dependent on City you just say that the class Person would not work without knowing about City (for example, because the operation sendPostCardFrom(city: City) needs an argument of that type) but you do not say anything about persons X, Y and Z. If you want that X, Y and Z are related to city a, b, and c, you need an association.

About the model content, I'll not decide for you and there is no single truth. I therefore prefer to draw your attention at potential issues. I raise them in form of a question, up-to you to adjust the model based on your own answer:

Common issues between the both variants:
- Are Actor and Director really Persons ? In this case, what with the Persons that are Actors and Directors at the same time (g.g. Clint Eastwood) ? Or are Actor and Director just roles that a Persons takes for a given Movie ?
- Is a Character really related only to 1 Movie? What to do with Indiana Jones, where the same character appears in several movies?
- In a similar way, I wonder if there's really a single Person who lives in a City or if this should not be a many-to-many association?
Issues regarding the differences: `
- Is a Person in version 1 a Character (inheritance) ? Or is a Character a representation of a Person (association: represents) ?
- Is a Character in version 2 really an Actor and by transitivity also a Person (inheritance)? Or is the Character only associated with an Actor (association: plays) ?

It's up to you to decide, but wherever I asked a question about association or inheritance, you should better think twice before using inheritance (i.e. prefer association/composition over inheritance)
