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.

I have events which is pulled from redux, and if the events array contains data, then updateData will be used to filter events into the state var data.
I have data and events both added to the dependency array as talked about here. but I'm still getting this error:

For a project for my study I am working on a React Native project, but I am stuck. I want to give the prop 'Score' to Card.js and based on that score a color has to be defined; 'transparancyColor'. Currently, the props are passed from Home.js to Card.js and the transparencyColor is defined there. Is this a smart way, or do I have to do this at Home.js? And how?
The code of Card.js looks as follows:

Answered 2021-Jun-15 at 09:10Regarding the code structure question, it's fine, especially initially, to pass props down one or two levels.
In terms of code, something like that (note the convention is to start variable names with lowercase):

QUESTION
Hello all!
I recently learned that in newer versions of SQL Server, the query optimizer can "expand" a SQL view and utilize inline performance benefits. This could have some drastic effects going forward on what kinds of database objects I create and why and when I create them, depending upon when this enhanced performance is achieved and when it is not.
For instance, I would not bother creating a parameterized inline table-valued function with a start date parameter and an end date parameter for an extremely large transaction table (where performance matters greatly) when I can just make a view and slap a WHERE statement at the bottom of the calling query, something like
ANSWER
Answered 2021-Jun-14 at 22:08You will not find this information in the documentation, because it is not a single feature per se, it is simply the compiler/optimizer working its way through the query in various phases, using a number of different techniques to get the best execution plan. Sometimes it can safely push through predicates, sometimes it can't.
Note that "expanding the view" is the wrong term here. The view is always expanded into its definition (NOEXPAND excepted). What you are referring to is called predicate pushdown.
I've assumed here that indexed views and
NOEXPANDare not being used.
When you execute a query, the compiler starts by parsing and lexing the query into a basic execution plan. This is a very rough, unoptimized version which pretty much mirrors the query as written.
When there is a view in the query, the compiler will retrieve the view's pre-parsed execution tree and shoves it into the execution plan, again it is a very rough draft.
With derived tables, CTEs, correlated and non-correlated subqueries, as well as inline TVFs, the same thing happens, except that parsing is needed also.
After this point, you can assume that a view may as well have been written as a CTE, it makes no difference.
Can the optimizer push through the view?The compiler has a number of tricks up its sleeve, and predicate pushdown is one of them, as is simplifying views.
The ability of the compiler here is mainly dependent on whether it can deduce that a simplification is permitted, not that it is possible.
For example, this query

QUESTION
My data set comes from an excel file set up by non-data orientated co-workers. My data is sensitive, so I cannot share the data set, but I will try to make an example so it's easier to see what I'm talking about. I have a unique identifier column. My problem is with the date columns. I have multiple date columns. When imported into R, some of the columns imported as dates, and some of them imported as excel dates. then some of the cells in the columns have a string of dates (in character type). not all the strings are the same size. Some have a list of 2, some a list 7.
I'm trying to Tidy my data. My thoughts were to put all the collection dates in one column. Here is where I'm stuck. I can use pivot_longer() bc not all the columns are the same type. I can't convert the excel dates into R dates w/out getting rid of the list of strings. And I can' get rid of the list of strings, bc I'm running into the Error: Incompatible lengths. I think my logic flow is wrong and any advice to point me in the right direction would be helpful. I can look up coding after i get my flow right.
