How to call a function when I press a button ??

Hello.
I'm making a new module, and the view I have a button that calls a function passed as parameter a char field. My intention is that when I press the fill another field with the description of the field that I pass as a parameter. The problem I have is that I have not made any button so far and I do not work well. I think the view I have no right to call the method declared "generar_nombre_producto" or that the .py, in the function declaration, I haven't the code correctly.

My code is as follows:

Code:

.......
         <field name="inherit_id" ref="product.product_normal_form_view"/>
         <field name="type">form</field>
         <field name="arch" type="xml">
            <field name="categ_id" position="replace">
                   <field name="categ_id" on_change = "onchange_categ_id(categ_id)"/>    
               </field>
            <xpath expr="/form/notebook[@colspan='4']/page[@string='Information']" position="after">
                 <page string="Información 2">
                     <group colspan="6" col="6">
                      ............
                      <field name="descripcionarticulo" colspan="3"/>
                      <button name="generar_nombre_producto(descripcionarticulo)" string="Generar nombre producto" type="object" icon="icon" colspan="3"/>
                      <field name="campoprueba" colspan="6"/>
                    </group>

and the .py ...

Code:

class product_product(osv.osv):
    _inherit = 'product.product'
    _name = 'product.product'
    
    .....

    _columns = {
        ......
        'descripcionarticulo' : fields.char('Descripción adicional', size=128),
        'campoprueba' : fields.char('campo prueba', size=256), 
    }
    
    def generar_nombre_producto(self, cr, uid, ids, descripcionarticulo_param):
        descripcionarticulo_obj = self.pool.get('product.descripcionarticulo')
        descripcionarticulo = descripcionarticulo_obj.browse(cursor,user,[descripcionarticulo_param])[0]
        #####descripcionarticulo_obj = self.browse(cr, uid, ids)
        #####descripcionarticulo = self.read(cr, uid, ids, ['product_id'],context)
        
        values = {}
        
        values = {'campoprueba' : descripcionarticulo}
        return {'value': values}
    
product_product()

I hope I have specified either my problem. Sorry for my English.

Anyone can help me??

Hi..

You can call a function from Button, but i beileve it should be parameterless function...

If i am right, you want to fill the field "campoprueba" with the same data as "descripcionarticulo".

If that is the case, then you can go for "On Change Event" method, which is more simpler and easier way..

Here the code will be as follows [In Python]

Code:

    def onchange_producto(self, cr, uid, ids, descripcionarticulo): 
        values = {}        
        if not descripcionarticulo:
            return {}        
        values = {'campoprueba' : descripcionarticulo}
        return {'value': values}

then [In XML]

Code:

<group colspan="6" col="6">                     
  <field name="descripcionarticulo" colspan="3" on_change="onchange_producto(descripcionarticulo)"/>       
  <field name="campoprueba" colspan="6"/>
<group>

Hope this helps..

Note: You can browse through the standard modules for examples on this
[hint: Use Ctrl + H for searching]

Thanks for your input deep.
The method "onchange" I've used it before and it works perfectly, but I really need to know how to call a function by passing parameters when I press a button.
Anyway thanks again.

Someone has the same problem?? Any help??

I don't know if this is possible or not, i have the same or similar problem, i want to fill the fields of a form reading the data from the first entry on res_partner, and on_change event it does not fit my requirements.

As far as i know, the only way is creating a workflow, i still need to dig about this.

Seem we cannot pass arguments on a button function, but, by default, the ids of actual object is passed.

We can use the ids to browse the object and obtain the record and the fields
---------------------------------------
Posiblemente tarde, pero para completar el hilo.

Parece que no puedes pasar argumentos en la función que llamas desde un botón, pero sin embargo si estás pasando el id correspondiente al registro del objeto, con lo que puedes cargarlo y leer los campos guardados.

Vista:

Code:

<field name="empresa_id" />
<button  icon="gtk-ok" name="boton_genera_instalaciones_detalles" string="Genera detalles" type="object"/>

Código:

Code:

def boton_genera_instalaciones_detalles(self,cr,uid,ids,context):
    detalles_obj =    self.pool.get('mantenimientos.instalaciones').browse(cr,uid,ids)
    print '--------self.empresa_id', detalles_obj[0].empresa_id.name
...

Un saludo

Have you tried sticking a context in and then pulling your args out of that?
context="{'somefieldinview':somefieldinview}"
