Input field constraint mechanism

摘要

A method of automating enforcement of a data validation rule associated with an input field by a Model View Controller software application includes applying an input constraint embodying the data validation rule to a Model to generate an applied constraint, discovering the applied constraint via examination of the Model by a View-Controller Generator to generate a discovered constraint, generating an input field constraint mechanism using the discovered constraint, and constraining the input field using the input field constraint mechanism to generate a constrained input field.
