Kii says value exists even though it doesnt?

[akisrn]

Hello, all!

So I'm making an app that will check if the user's promo code exists in my database of promo codes. It was working a while ago but now, I dont know why it suddenly returns everything as valid? Here is my code:

        string coupon_code = input_code.text;
    	// Prepare the target bucket to be queried.
    	KiiBucket bucket = Kii.Bucket("PromoCodes");
    
    	// Create a query with clauses.
    	KiiQuery query = new KiiQuery(KiiClause.And(KiiClause.Equals("Promo Code", coupon_code)));
    	query.Limit = 1;
    
    	// Query KiiObjects.
    	bucket.Query(query, (KiiQueryResult<KiiObject> result, Exception e) => {
    			if (e != null)
    			{
    				Debug.Log(e.ToString());
    				return;
    			}
    			else
    			{
    				if (result != null)
    				{
    //					foreach (KiiObject obj in result)
    //					{
    //						Uri id = obj.Uri;
    //						KiiObject appObj = KiiObject.CreateByUri(id);
    //
    //						appObj.Refresh((KiiObject refreshedObj, Exception d) => {
    //							if (d != null)
    //							{
    //								Debug.Log(d.ToString());
    //								return;
    //							}
    //							string discount_amount = (string)refreshedObj ["Discount Amount"];
    //
    //							Debug.Log("Code valid! Discount amount is : " + discount_amount);
    //						});
    //
    //					}
    					Debug.Log("Coupon Code Valid");
    				}
    				else
    				{
    					Debug.Log("Invalid Coupon Code");
    
    				}
    			}
    
    		});

Hi.

Have you checked "PromoCodes" bucket contents?

You can check it from developer console.

Probably, it is because you're using App Scope bucket to storing the promo code.
If you create a promo code object to a user, It will be visible to other users as well.
Please consider using User Scope bucket.
Details about the scope.

Hi! Yes, I have checked the contents of my bucket. I only added 4 values for testing. In my app, I tried entering invalid codes on purpose for checking but Kii returns it's valid even though the value doesnt exist in my bucket. Also, I put it in App scope so anyone with the promo code can check if it's valid or not. Am I doing something wrong?

I think the problem is that the code is judging valid or not by whether the bucket is empty or not.
And probably bucket is not empty.

That makes sense. What if I only want to check if the user input exists in my bucket?

I solved this by changing my code to this. Thanks for the help

if (result.Count != 0)
				{
//					string discount_amount = (string)result["Discount Amount"];
//					Debug.Log("Code valid! Discount amount is : " + discount_amount);
					Debug.Log("Code valid!");
				}
				else
				{
					Debug.Log("Code invalid!");
				}

Good catch

I still recommend you to use User Scope Bucket from security point of view.

The contents in the App Scope bucket is visible to all users and users can see the contents if they use API even your app hide it. (Not all users. but some might do the hack if the code is valuable)
