RequiredIf - Boolean values

Sep 27, 2010 at 4:01 PM

Just started using Foolproof after finding it while searching for more validators for MVC. As luck would have it, the first validation scenario I needed failed with foolproof on the client side. Server side validation executed correctly, but the client side did not. I was using the RequiredIfTrue and RequiredIfFalse validators, and the problem seems to be how my boolean value in the view model was being rendered in the view.

public class EditModel(){

public string Description { getset; }
public bool IsSystem {get;set;}


In my view I was rendering IsSystem as a hidden field, which gets a value of either True or False (capital T/F). Reviewing the javascript code, I noticed that there is a check made for "true" and "false" with a lower case T/F. Adding in some adidtional OR statements to also look for True/False seems to have fixed this for me. I had the problem with both the MVC and Jquery validation, but only looked at the Foolproof JQuery script. I changed lines 11, 12, and 13 to be:

else if (value1 === true || value1 === false || value1 === "true" || value1 === "false" || value1 === "True" || value1 === "False") {
        if (value1 == "false" || value1 == "False") value1 = false;
        if (value2 == "false" || value2 == "False") value2 = false;
        value1 = !!value1;
        value2 = !!value2;

I re-ran the javascript unit tests, and they all passed, so at least I havn't broken anything. I wanted to get some feedback on if this was a good way to fix this, or if I should be looking at trying to adjust how my model (boolean values) are rendered.

Salvoz, check out this thread, let me know if this is the same issue and if the referenced change set works for you:

I saw that thread before I downloaded, so I started with the latest source as of Monday. Steping thru the javascript code in Firebug I skip over the reference javascript because I'm comparing against a hidden field, not a checkbox. As I mentioned in my first thread I was able to get the desired behvior by adding checks for true/false with a capital T and F.

Excellent, works like a charm for me now.

I put a .ToLowerCase() on values where needed and it works great.
