Hello,

I've added an additional status (draft, sale, etc) to the state field of the sales order model and I would like to add it to the sales order form.

I am using the following xpath sequence to do so:

<xpath expr="//field[@name='state']" position="attributes">    
          <attribute name="statusbar_visible" >{new_status}</attribute>
</xpath>

The problem is that xpath replaces all the existing values (draft,sent,sale )of the attribut statusbar_visible !

I've searched over the net but I didn't found a way to add one attribute value to the existing ones.

Does anyone knows how I can do this (without hard coding the existing values in the xpath sequence) ?


Thanks !

HI Avinash and thank you for your answer!

I already extended the sale order model adding the new value to the state selection field.

I fully agree with you I can simply write all the standard attribute values plus my new one in the attribute field inside the xpath locator.

But if I do this, I am actually overriding the existing sale.order attribute values.

What I would like to do is just add my new value attribute to the others, so if one day Odoo decides to create a new state to this model I won't be overriding it without knowing

Do you think is there a way to insert a attribute value into the existing ones without overriding the whole statusbar_visible attributes?

Thank you!!

Use the add and separator properties of the <attribute> tag.

Take for example the following template from addons/website_blog/views/website_blog_templates.xml 

    203 <!-- Option: Blog Post List: grid layout -->
    204 <template id="opt_blog_post_grid_layout" name="Grid view"
    205         customize_show="True" active="False" inherit_id="website_blog.blog_post_short">
    206     <xpath expr="//div[@name='blog_post']" position="attributes">
    207         <attribute name="class" add="col-sm-5 o_grid" separator=" "/>
    208     </xpath>
    209 </template>

This is an old post, I appreciate you still leave the correct answer for reference.

I just tested on Odoo 12 CE, works great! Thank you.

Hi,

Please add previous values and new values both in the attributes.

eg:

How to add new values to state

state = fields.Selection(selection_add=[('new_state', 'New State')])

for visible the value in the form view

<xpath expr="//field[@name='state']" position="attributes">
    <attribute name="statusbar_visible">draft,sent,sale,new_state</attribute>
</xpath>

Thank you
