Magento 1.9 Block is not showing the data on front page in custom module

Question

Created a module for front-end to show data from custom table but it is showing a blank page.

Here is the config.xml file:

<?xml version="1.0"?>
<config>
<modules>
    <MageSf_OrderCustom>
        <version>1.0.1</version>
    </MageSf_OrderCustom>

    </blocks>

            <entities>
                <ordercustom>
                    <table>magesf_ordercustom</table>
                </ordercustom>
            </entities>
        </magesf_ordercustom_resource>
    </models>

    <resource>

            </modules> 
        </args>
   </adminhtml>        
</routers>

</config>

Here is the layout xml file for my module:

<?xml version="1.0"?>
 <layout version="0.1.0">
   <customer_account>        
      <reference name="customer_account_navigation">           
        <action method="addLink" translate="label" module="ordercustom">
           <name>ordercustom</name>
           <path>ordercustom/customer/view</path>
           <label>Order Attachments</label>
        </action>
      </reference>
   </customer_account>   

 <ordercustom_customer_view> 
    <update handle="customer_account"/> 
        <reference name="content">    
            <block type="ordercustom/customer" name="view.ordercustom" template="ordercustom/customer/view.phtml"/> 
        </reference> 
 </ordercustom_customer_view>
</layout>

And My controller file is as follows:

<?php


 class MageSf_OrderCustom_CustomerController extends   Mage_Core_Controller_Front_Action
  {    

  public function preDispatch()
{
       parent::preDispatch();

       if (!Mage::getSingleton('customer/session')->authenticate($this))    {
        $this->setFlag('', 'no-dispatch', true);

    // adding message in customer login page
    Mage::getSingleton('core/session')
            ->addSuccess(Mage::helper('ordercustom')->__('Please sign in or create a new account'));
    }
  }            
/**
 * View Your Module
 */

public function viewAction() {

  $this->loadLayout();   
  $this->getLayout()->getBlock("head")->setTitle($this->__("Order Attachments"));
        $breadcrumbs = $this->getLayout()->getBlock("breadcrumbs");
  $breadcrumbs->addCrumb("home", array(
            "label" => $this->__("Home Page"),
            "title" => $this->__("Home Page"),
            "link"  => Mage::getBaseUrl()
       ));

  $breadcrumbs->addCrumb("titlename", array(
            "label" => $this->__("Attachments"),
            "title" => $this->__("Attachments")
       ));

  $this->renderLayout(); 


     }
   } 
?>

My Block code is as :

<?php


 class MageSf_OrderCustom_Block_Customer extends Mage_Core_Block_Template
 {
 public function view()
 {
    echo "Hello World";
    $data = Mage::getModel('magesf_ordercustom/ordercustom')->load();

    $collection = $data->getCollection();
    return $collection;

   }

}

?>

And at last my model looks like follows:

<?php

  class MageSf_OrderCustom_Model_Ordercustom extends Mage_Core_Model_Abstract
  {
     public function _construct()
       {
         parent::_construct();
         $this->_init('magesf_ordercustom/ordercustom');
       }
  }
 ?>

View.phtml file just printing the whole collection:

<?php 

    $collection = $this->view();
        print_r($collection);

 ?>

Can anyone just check where i have done wrong and how i can fix it to show the data from my custom table.

Answer 1

in your block class change code as below , because in your code you load the model and then call collection, I think that is not right

<?php


 class MageSf_OrderCustom_Block_Customer extends Mage_Core_Block_Template
 {
 public function view()
 {
    echo "Hello World";
    $data = Mage::getModel('magesf_ordercustom/ordercustom');

    $collection = $data->getCollection();
    return $collection;

   }

}

?>

and also remove below code from your config.xml

    <magesf_ordercustom>
        <class>MageSf_OrderCustom_Block</class>
    </magesf_ordercustom>
