How to add two more fields when I edit a record, and update another table also


In order to normalize the database and avoid duplicate fields need to make this change in the structure of the database:


trabajadores_before.jpg
after:
trabajadores_after.jpg

As seen, i remove  id_provincia and id_municipio fields of trabajador table, and then it will not leave these fields when adding or editing the main table (trabajador) with GC.


How do I keep these two fields to add or edit records.


And in edit record of trabajdor table, as knowing the id_municipio and id_provincia through id_consejo_popular ? :wacko:

What do you mean remove? Not including them when you call the fields function?

If this is what you mean then your way of thinking isn't probably correct.

 

What I see from the first part (before as you declare it) of your DRD is that trabajador table has 3 foreign keys,

id_consejo_popular,

id_municipio and 

id_provincia

 

For Grocery CRUD to work correctly you need to setup three (3) different set_relation functions.

By the time you do this you don't need to worry about anything else since internal integrity of the tables is fully syncronized

(because of the 1-n relation between trabajador->consejo_popular, trabajador->provincia, trabajador->municipio).

 

I hope this helps you.

Yes, I understand that, but as I need this for a school, is very strict normalize the database correctly, because so saving two columns (id_provincia and id_municipio) in table (employee)

i have 3 set_relation
 

$crud->set_relation('id_municipio','municipio','desc_municipio');
$crud->set_relation('id_provincia','provincia','desc_provincia');
$crud->set_relation('id_consejo_popular','consejo_popular','desc_consejo_popular');


but I want to know if I can do something like:
 

$crud->set_relation('consejo_popular.id_municipio','municipio','desc_municipio');


I understand how it works Grocery CRUD, but I want to see if I can change something, create another extended model grocery_CRUD_Model or something to make operating the GC with my normalized database.

if recently found a temporary "solution"

I removed:

$crud->set_relation('id_provincia','provincia','desc_provincia');
$crud->set_relation('id_municipio','municipio','desc_municipio');

And then added: (id_provincia, id_municipio) to display the selectbox to Add / Edit

$crud->fields('field1','field2','field3','id_provincia','id_municipio');

By adding (id_provincia, id_municipio) to form, fails to save because these fields do not exist in the database, then:
 

// CALL DELETE THE FORM FIELDS UNAVAILABLE
    $crud->callback_before_insert(array($this,'_callback_before'));
    $crud->callback_before_update(array($this,'_callback_before'));


And the relevant function
 

// REMOVE EXISTING FORM NO FIELDS
    function _callback_before($post_array)
    {
    unset( $post_array['id_provincia'] );
    unset( $post_array['id_municipio'] );
    return $post_array;
    }

Just need to use a:
 

$crud->callback_field ( 'id_provincia', array ( $this, '_callback_field_provincia' ) );
$crud->callback_field ( 'id_municipio', array ( $this, '_callback_field_municipio' ) );

to fill the added selectbox
