Frequently asked questions

Q: Is the arrow between the view and the user incorrect? The user sees the view, not the other way around. (Jan. 2021)

A: This problem has been pointed out repeatedly. The arrows in the diagram show the flow of action through the pattern, so it is not the arrow that is wrong, but the label; "informs" might be more appropriate. If you have graphic design skills, please consider creating and uploading a corrected diagram under a different filename. You do not need permission.

Picture issue

I share sentiment with comment above , that picture is disturbing . users (clients) should only interact with view objects while controllers 'goes' between views and model(data). 41.77.91.206 (talk) 07:17, 17 December 2021 (UTC)[reply]

I also concur. The diagram is incorrect. There's no direct interaction between the Model or View. WanderingFido (talk) 10:05, 17 January 2022 (UTC) ^[1][reply]

According to Krasner and Pope 1988: "The model carries out the prescribed operations, possibly changing its state, and broadcasts to its dependents (views and controllers) that it has changed, possibly telling them the nature of the change. Views can then inquire of the model about its new state, and update their display if necessary." so Model-View interaction is part of MVC as described in the original literature. But I do think there is room for improvement. The original literature includes the input and display devices as part of the diagram and also differentiates between state "change messages" and "access/editing messages". It may be useful to portray that distinction here. Elplatt (talk) 19:32, 26 January 2022 (UTC)[reply]
