            How to use MVVM with EF (with a pretty complex database in SQLite)?
            Asked 2021-Jun-08 at 13:57

            I'm trying to have an MVVM architecture while Models are EF Models too.

            In Code :

            Model:

            ...

            ANSWER

            Answered 2021-Jun-07 at 14:12

            This is a very large topic and I doubt that it will fit the format adopted here.
            Therefore, I will briefly outline only the main points.

            It is customary to implement WPF using the MVVM pattern.
            It is a strict 3-tier architecture: View (WPF) -> ViewModel -> Model. The Model is responsible for working with "real" data - this is the so-called Business Logic. View is responsible for creating the GUI.
            The peculiarity of WPF is that the UI elements themselves request the data they need through the bindings.
            Bindings are created (mostly) to the DataContext.
            Therefore, it is necessary to put some special custom type there, which is responsible for the links between the View and the Model.
            This type is called ViewModel.
            In a typical implementation, the Model basically receives / returns data via methods.
            And bindings need properties.
            Therefore, one of the main functions of the ViewModel is to provide all the data necessary for the View in its properties.

            When an application works with a database, it is customary in Sharpe to implement this in the Repository (Data) pattern.
            From the MVVM point of view, such a Repository is part of the Model. But, for a simpler understanding, to facilitate software maintenance, the Repository is usually implemented in a separate layer.
            As a result, we get a four-tier architecture: View -> ViewModel -> Model -> Repository.

            According to the rules and principles of OOP, SOLID in a layered architecture, each layer "knows" (has information) only about the underlying layer.
            And all non-public information must be encapsulated inside the layer.

            EF entities reflect database data, they are mutable, and can have corresponding attributes.
            When changing the source, these types can change.
            Let's say you, at some point, want to use a set of XML files instead of a database.
            And they need entities of a different type.
            Therefore, such entities are the internal implementation of the Repository. And to exchange data with the Model, the Repository must be either Model types or generic DTO types.

            At the next level, the ViewModel must also receive data from the Model.
            But Model types cannot be used here, since they can be implicitly associated with Business Logic and there is a possibility of creating parasitic connections leading to unpredictable bugs.
            At this level (ViewMode-> Model), exclusively DTO types are used for data exchange.
            They are preferably immutable.

            The next level of exchange of View with ViewModel.
            First, the GUI often needs mutable properties. And to auto-update the property view, the type MUST implement INotifyPropertyChanged.
            Secondly, to call actions from the GUI, the ViewModel must provide COMMANDS in its properties - this is the ICommand implementation.
            For my answers here, I am using the BaseInpc and RelayCommand classes.
            Thirdly, in types for View, additional properties are often needed to ensure the logic of the GUI operation: a selected element, an expanded element, instead of the Id of the record, an element reflecting it, etc.
            For these reasons, at the ViewModel level, you already need your own types with an implementation other than DTO.

            As a result of the above, we can get four different implementations for the type reflecting some record in the database.
            The area of ​​use of each type will be in one or two layers.
            In order not to get confused in all this, it is better to do each layer in a separate project.
            Types used only within the layer are implemented in this project.
            The types used by several layers (for example, DTO) are implemented in separate libraries (maybe for simple tasks and one common library).
            To maintain abstraction, it is desirable to do all implementations through the preliminary declaration of interfaces.
            And transfer information between layers through these interfaces.

            You should take a look at trackBy. It will tell your ngFor to only rerender what changed based on what you are tracking. It's hard to tell if it can work in your case but there is no other solution since as soon as the array changes, angular loose track of what's going on and needs to render the *ngFor again.

            It would look like that:

            I found a quite interesting example of multi-touch trackpad gestures in JavaScript.

            The code snippet below utilizes this for overriding LCJS chart interactions for trackpad. To me it seems to perform in a surprisingly intuitive manner for zooming in/out on pinch interaction (2 fingers, move to opposite directions) and panning with dragging 2 fingers in same direction.

            I did not find any way to differentiate pinch interaction along X and Y separately, it seems that the JS events just get a single value for both, which is assigned to deltaY.

            Part of the issue here is that your code is checking against an offset of 300, not 100 as described in the question text -- which means it's impossible to trigger a false condition (because the element is 300px square.)

            Changing your code to check an offset of 100px instead shows it mostly working... but the test for showing the menu also compares against the menu's offsetWidth and offsetHeight, both of which change to zero when the element is display:none, which throws off your calculation.

            Finally, you're adding the offsetHeight instead of subtracting it as intended (the only reason this appeared to work was when what you were adding was actually zero.)

            Here's the result of correcting the math, and using visibility instead of display to control whether the child is shown (visibility keeps the element's original size intact):

            Every signal connection triggers the target slot (function). If you connect the same signal to two functions, both functions get called, even if you connect twice to the same function. In fact, when you say "menu is not close[d] quickly after select[ing] the item", the truth is that the menu is opened multiple times. You can easily check that if you just add a print statement to each function.

            There are different solutions depending on the situation (unfortunately, your code and function namings aren't very verbose, so we cannot really know what every function does).

            Disconnect from all other slots

            This can be done by calling a simple disconnect() on the signal, which disconnects from all other (already) connected slots. Note that this would raise an exception if no connection exists, so it should be done inside a try/except block:

            It looks like the problem is at code level. If the file shows in photoscene, but has a zero filesize, it means that the file was allocated, but the "upload protocol" is wrong. From my humble experience, it is usually due to wrong content-type or file upload.

            I am not very "tech savvy" in Unity, nor in C#, but my suggestion would be to try uploading it not as "multipart/form-data", but rather as "application/x-www-form-urlencoded".
