How to modify the default value of a property field in Odoo 8?

Question

I am trying to modify the default value of the Sale Pricelist of a partner (field property_product_pricelist, tab Sales & Purchases, model res.partner). It seems that this default value was introduced via XML (since that field is of type property), adding a record to the ir.property model:

<record id="list0" model="product.pricelist">
    <field name="name">Public Pricelist</field>
    <field name="type">sale</field>
</record>
<record id="ver0" model="product.pricelist.version">
    <field name="pricelist_id" ref="list0"/>
    <field name="name">Default Public Pricelist Version</field>
</record>
<record id="item0" model="product.pricelist.item">
    <field name="price_version_id" ref="ver0"/>
    <field name="base" ref="list_price"/>
    <field name="sequence">1000</field>
    <field name="name">Default Public Pricelist Line</field>
</record>

<!--
Property
-->
<record forcecreate="True" id="property_product_pricelist" model="ir.property">
    <field name="name">property_product_pricelist</field>
    <field name="fields_id" search="[('model','=','res.partner'),('name','=','property_product_pricelist')]"/>
    <field eval="'product.pricelist,'+str(ref('list0'))" name="value"/>
</record>

So I guess (I did not try it) that if you modify this XML record, you will change the default value, for example:

<record forcecreate="True" id="product.property_product_pricelist" model="ir.property">
    <field name="name">property_product_pricelist</field>
    <field name="fields_id" search="[('model','=','res.partner'),('name','=','property_product_pricelist')]"/>
    <field eval="'product.pricelist,'+str(ref('my_default_pricelist'))" name="value"/>
</record>

The problem is that I want to introduce different default values depending on other field (user_id). I mean, if user_id is the res.users with ID 1, I want the Public Pricelist as the default pricelist, otherwise, I want the pricelist created by me (my_default_pricelist) as the default one.

Can anyone help me, please?

If you want conditional default values you have to move to Python.

Try extending the model and redefining the field but this time use the fnct=compute_method argument. compute_method is the method that will run each time to set the default value of the field.

The property class that the property_product_pricelist field is using, is an extension of the function class. Go to openerp/osv/fields.py and find the definition of the function class and take a look at the parameters.
