Validation / Notification for missing values

[skjerns]

Implement a way to validate the database input that is displayed on the current page, e.g. if an email is incorrectly formatted.

mainly to sanitize input that has been made before

@skjerns The first part is is unclear to me; on what "current page"? Also if the data is displayed, how is it used as "database input"?

I probably meant the pagination / list view of current rentals/items/customers. such that missing fields are highlighted in this view (e.g. by highlighting the cell that has incorrect/missing data).

However, currently I'd say that validation of input when creating new entries is more important and easier to implement (in the popup).
