How to set default value for form fields - Magento?

I have an admin form field (textbox),

$fieldset->addField('ajax_time_interval', 'text', array(
          'label'     => Mage::helper('dealroom')->__('Page Refresh Time Interval'),
          'class'     => 'required-entry',
          'required'  => true,
          'name'      => 'ajax_time_interval',
      ));

I need to set a default value for this textbox. I tried setting it to "value" => '120'. But it doesn't work.

$fieldset->addField('ajax_time_interval', 'text', array(
          'label'     => Mage::helper('dealroom')->__('Page Refresh Time Interval'),
          'class'     => 'required-entry',
          'required'  => true,
          'name'      => 'ajax_time_interval',
          'value'     => '120', 
      ));

How do I set the defalt value in this field?

In my case, the function was setValues()

overriding the value ' I set for this field.

Cause:

In my function, _prepareForm()

I am setting the value as shown below:

$fieldset->addField('ajax_time_interval', 'text', array(
          'label'     => Mage::helper('dealroom')->__('Page Refresh Time Interval'),
          'class'     => 'required-entry',
          'required'  => true,
          'name'      => 'ajax_time_interval',
          'value'     => '120', 
      ));

At the end of the function _prepareForm()

, the following line of code appeared to reset the form values:



$form->setValues($model->getData());

Decision:

Set the model data before setValues()

as shown below:

if (!$model->getId()) {
    $model->setData('ajax_time_interval', '120');
}
$form->setValues($model->getData());

you can do this by adding a "default" attribute in the field config.



$fieldset->addField('ajax_time_interval', 'text', array(
          'label'     => Mage::helper('dealroom')->__('Page Refresh Time Interval'),
          'class'     => 'required-entry',
          'required'  => true,
          'name'      => 'ajax_time_interval',
          'default'     => '120', 
      ));
