Hello, 

I encounter a problem I explain: I have a model 'Patient' inherits from res_partner I had a link to have visibility of the total charged to the patient the problem is that when I make up the field ' partner_id '  my link works but to create a record , the field must be filled partner_id.

I do not know how to fix the problem

<div class="oe_button_box" name="button_box">  
<field name="partner_id" attrs="{'invisible':1}" />  
<button class="oe_stat_button" type="object" name="consultation_meeting" icon="fa-calendar">    
<field string="Visite(s)" name="consultation_count" widget="statinfo" modifiers="{'readonly': true}"/>
</button>  
<button type="action" class="oe_stat_button" id="invoice_button" icon="fa-pencil-square-o" name="205" context="{'search_default_partner_id':partner_id,'default_partner_id':partner_id}">    
<div class="o_form_field o_stat_info">      
<span class="o_stat_value">        
<field name="total_invoiced" widget="monetary" options="{'currency_field': 'currency_id'}" modifiers="{'readonly': true}"/>      
</span>      
<span class="o_stat_text"> Facturé </span>    
</div>  
</button>
</div>
