view | A base view that handles state and properties

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.

The issue you are having has nothing to do with templates. You cannot invoke std::async() on a member function without binding it to an instance. Wrapping the call in a lambda does the trick.

Here's an example:

Remove your agreement vars in MinimalClone.sol, and either have the user input them as args in your init() method or hardcode them into the request like this:

If you're going to use the CompareOptions enum, I feel like you might as well use it with the CompareInfo class that it's documented as being designed for:

Defines the string comparison options to use with CompareInfo.

Then you can just use the GetHashCode(string, CompareOptions) method from that class (and even the Compare(string, string, CompareOptions) method if you like).

when the program finishes my excel data frame is not changed at all.

That's because you never wrote anything to the Excel file. With exc = pd.read_excel('...') you create a Python object exc (more specifically, a pandas DataFrame), and all the subsequent modifications happen to this object. To change the source file accordingly, you can use pandas' DataFrame.to_excel() method, by adding this line in the end:

At the top off your controller add

The problem is that you are not aligning the text within the individual Views. Your example mistakenly aligns the inner View elements within the larger View element rather than aligning the text.

To center-align the text vertically within their Views you just need to add justifyContent: "center" to those individual three green Views.

To further explain why you were experiencing the issue you did, see this screenshot with boxes outlining the space the elements were taking up on-screen:

You can see the inner Views are only taking up the needed width of the text elements inside, but are using the max height available to them.

The problem is that you are using an empty notesListAll list for filtering results; you need to populate it with the list of notes in the constructor
