Update custom object field with Visualforce page form

Hi,
I have stripped my code back to the bare minumum as I am having lots of trouble trying to make a form with one field.  The field needs to submit the string "submitted" when the user hits the submit button.

My Error in the VFP
<blockquote>Unknown property 'leadershipReadyCon.Leadership_Ready__c'</blockquote>

My APEX Class code 
public with sharing class leadershipReadyCon {

	 public final Leadership_Ready__c myLeadershipReady;
    
	//Constructor function
    public leadershipReadyCon() {
        myLeadershipReady = [SELECT Id, Automated_TP_Status__c FROM Leadership_Ready__c 
                   WHERE Id = :ApexPages.currentPage().getParameters().get('prodId')];
    }
    
    Leadership_Ready__c lr = new Leadership_Ready__c();
    
    

    public Leadership_Ready__c getLeadershipReady() {
        return myLeadershipReady;
    }

    public PageReference save() {
        //Add your custom logic to update specific fields here 
        //e.g. myLeadershipReady.email = 'xx@xx.com'; 
        update myLeadershipReady;
        return null;
    }        
}

Here is my Visual Force Page code  
<apex:page controller="leadershipReadyCon" tabStyle="Leadership_Ready__c">
    
    <apex:form >
        
        <apex:pageBlock title="Automated Training Plan Status">
            You belong to Account Name: <apex:inputField value="{!Leadership_Ready__c.Automated_TP_Status__c}"/>
            <apex:commandButton action="{!save}" value="save"/>
        </apex:pageBlock>
    </apex:form>
</apex:page>

Any help would be great, I don't know if this is the best way to submit data to a field in SFDC with APEX so if I am totaly on the wrong track, please let me know.

Thanks.

Hi Joe,

There are some modifications needed in your code. Please find the code below.
  
public with sharing class leadershipReadyCon {

  // After declaring final you can not modify any record.	 
  //public final Leadership_Ready__c myLeadershipReady;
    
// getter and setter required to access and update record field from page.
    public Leadership_Ready__c myLeadershipReady {get;set;}
   
    
	//Constructor function
    public leadershipReadyCon() {
       //Initialize  first to avoid null error.
        Leadership_Ready__c myLeadershipReady  = new Leadership_Ready__c();
        
        // if there is any record found then it will assign to myLeadershipReady otherwise we have already Initialize it.
         for(Leadership_Ready__c  lr : [SELECT Id, Automated_TP_Status__c FROM Leadership_Ready__c  WHERE Id = :ApexPages.currentPage().getParameters().get('prodId')]){
             myLeadershipReady =  lr;
    }
    

    public PageReference save() {
        //Add your custom logic to update specific fields here 
        //e.g. myLeadershipReady.email = 'xx@xx.com'; 
        update myLeadershipReady;
        return null;
    }        
}

<apex:page controller="leadershipReadyCon" tabStyle="Leadership_Ready__c">
    
    <apex:form >
        
        <apex:pageBlock title="Automated Training Plan Status">
           <!-- You belong to Account Name: <apex:inputField value="{!Leadership_Ready__c.Automated_TP_Status__c}"/>
                 Always you your variable not the object as you can see in code below.
               -->
             You belong to Account Name: <apex:inputField value="{!myLeadershipReady.Automated_TP_Status__c}"
             
            <apex:commandButton action="{!save}" value="save"/>
        </apex:pageBlock>
    </apex:form>
</apex:page>

Thanks for your help Kapil, I appricate the comments in the code.  Very helpful.

I am getting 4 different errors with the new code.  I have added them in the code as comments starting with //error at the related line.
  
public with sharing class leadershipReadyCon {

  // After declaring final you can not modify any record.	 
  //public final Leadership_Ready__c myLeadershipReady;
    
// getter and setter required to access and update record field from page.
    public Leadership_Ready__c myLeadershipReady {get;set;}
   
    
	//Constructor function
    public leadershipReadyCon() {
       //Initialize  first to avoid null error.
        Leadership_Ready__c myLeadershipReady  = new Leadership_Ready__c();
        
        // if there is any record found then it will assign to myLeadershipReady otherwise we have already Initialize it.
         for(Leadership_Ready__c  lr : [SELECT Id, Automated_TP_Status__c FROM Leadership_Ready__c  WHERE Id = :ApexPages.currentPage().getParameters().get('prodId')]){
             myLeadershipReady =  lr;
    }
    
	//error unexpected token: 'public'
	//error unexpected syntax: 'missing SEMICOLON at 'save''
	//error unexpected syntax: 'missing SEMICOLON at '{''
        public PageReference save(){
        //Add your custom logic to update specific fields here 
        //e.g. myLeadershipReady.email = 'xx@xx.com'; 
        update myLeadershipReady;
        return null;
    }        
}
//Error unexpected syntax: 'mismatched input '<EOF>' expecting RCURLY'

Thanks Kapil

Ok so the issue was it was missing a curly braket down the bottom.  I fixed that so the code compiled and now when I hit the save button I get this error:

System.NullPointerException: Attempt to de-reference a null object
Error is in expression '{!save}' in component <apex:commandButton> in page inputfieldhelloworld: Class.leadershipReadyCon.save: line 28, column 1
Class.leadershipReadyCon.save: line 28, column 1

Do I need to return something?

HI Joe,

Sorry for the late reply. I think you are not sending recordid while opening your page. Make sure your page url look like "https://c.ap4.visual.force.com/apex/yourpageName?id=0036F00002D4xt8"

https://c.ap4.visual.force.com ==> your org baseurl
id= YourRecordId

Regards,
Kapil

public PageReference save(){
        update myLeadershipReady;
        return new PageReference ('/'+myLeadershipReady.id);
    }

If you want to redirect on record's detail view.
