Controller action does not display errors and I cannot see whats wrong


Controller action does not display errors and I cannot see whats wrong

I wish this help you You're using AJAX to make the call to your create action, and in your $.post function you're configuring it to receive 'json' therefore, you can only receive json from the create action. So, you can't do a redirect_to in that action. Instead, you must return the error as json and process that response in your $.post function.
The reason you're not seeing anything except in the server log is because the $.post function will ignore the response because it's not json. It doesn't know what to do with it so it silently fails.

it fixes the issue First one: The methodname doesn't exist. You meant ot write objectAtIndex instead of objectAt. When it says that the object might now respond to the '-something' it's because the methods isn't declared in the header file. This results in the compiler not being sure whether or not the method exists in the implementation file or not. When you're using built-in classes (NSArray, NSView etc.) these kinds of warnings usually means that you misspelled a method-name. The only thing to do is to lookup in the documentation and doublecheck. These kind of type-mistakes will cause a crash in the app when trying to send a message to an object which doesn't repond to the selector.
Second one: That's just a warning telling you that a variable isn't being used. Remove the line. As you can see soundToPlay isn't being used in the playSound method, it's only being declared. If you use it fx. with a NSLog function call or in a method this warning should disappear.
code :
soundArray = sounds
Whats the difference between a front controller plugin and an action helper?

Whats the difference between a front controller plugin and an action helper?

Any of those help A front controller plugin executes for every request, at specific stages in the MVC cycle. You can use it to perform work like checking whether a user is authenticated or logging requests to a database for analytics.
A controller action helper can also perform at different stages of the MVC cycle, though this isn't mandatory. The key difference between plugins and action helpers is that your controllers can interact with action helpers to change their behaviour, or use some on-demand functionality.
code :
public function init() {
   $this->_helper->myHelper->setAuthenticationRequired(false);
}

I hope this helps you . This code won't compile. Need to change the following for it to compile successfully at least:
We are using a float (month) variable as an array index, which is not a valid syntax. Need to change type of month to int. After changing month to int, input.nextFloat(); needs to be changed to input.nextInt(); System.out.printIn needs to be changed to System.out.println
3 errors. Im new to coding any ideas whats wrong?

around this issue if your if statement is more than one line, you have to put brackets around the body:
code :
if(delta > 0)
{
    Console.WriteLine("x1={0}", (-b-Pdelta)/(2*a));
    Console.WriteLine("x2={0}", (-b+Pdelta)/(2*a));
}
