Usage of field_array.php file?

[sugarcrmvn]

Hello all,
This is the content of field_array.php of Account module:

 $fields_array['Account'] = array ('column_fields' => Array(
        "annual_revenue"
        ,"billing_address_street"
        ,"billing_address_city"
        ,"billing_address_state"
        ,"billing_address_postalcode"
        ,"billing_address_country"
        ,"date_entered"
        ,"date_modified"
        ,"modified_user_id"
        ,"assigned_user_id"
        ,"description"
        ,"email1"
        ,"email2"
        ,"employees"
        ,"id"
        ,"industry"
        ,"name"
        ,"ownership"
        ,"parent_id"
        ,"phone_alternate"
        ,"phone_fax"
        ,"phone_office"
        ,"rating"
        ,"shipping_address_street"
        ,"shipping_address_city"
        ,"shipping_address_state"
        ,"shipping_address_postalcode"
        ,"shipping_address_country"
        ,"sic_code"
        ,"ticker_symbol"
        ,"account_type"
        ,"website"
        , "created_by"
 
 
 
        ),
        'list_fields' => Array('id', 'name', 'website', 'phone_office', 'assigned_user_name', 'assigned_user_id'
    , 'billing_address_street'
    , 'billing_address_city'
    , 'billing_address_state'
    , 'billing_address_postalcode'
    , 'billing_address_country'
    , 'shipping_address_street'
    , 'shipping_address_city'
    , 'shipping_address_state'
    , 'shipping_address_postalcode'
    , 'shipping_address_country'
 
 
 
 
        ),
        'required_fields' => array("name"=>1),
); 
  

Somebody can explain the meaning of "comlum_fields, list_fields, required_fields"?

Many thanks,

yeah it's one year later.. what the heck. I was researching the same thing you asked.

From another thread:
"You need to include the field defs in two places in the class (regular vars, and the array column_fields) and also in the vardefs.php file for the module."

So it looks like every new field must be declared in 3 places: vardefs.php, column_fields, and as a regular var in bean.php. I've noticed that some modules have fields listed in list_fields instead of column_fields.

I've noticed that some people declare column_fields within bean.php . Some people use a seperate field_array.php.

This is all based on my observations while trying to comprehend the new module development process. Please correct me if Im wrong.
