How to define link text different in Odoo widget=url

Question

I have made read only computed URL-field based on invoice number. It works nicely but I would like to produce text part only itself like 400:

<a href="https://external_site_invoice?num=400">400</a>

Now it's producing whole link as text which is quite ugly

<a href="https://external_site_invoice?num=400">https://external_site_invoice?num=400</a>

My Odoo fields are defined this way...

ext_invoice_number= fields.Integer(string="Ext number")

def _showlink(self):
    for rec in self:
        if rec.ext_invoice_number:
            if  rec.ext_invoice_number>0:
                rec.ext_link="https://external site/invoice?num=%d" % (rec.ext_invoice_number,)


ext_link = fields.Char(string="Link",compute=_showlink,)

How can I define text part of URL in Odoo to be different than link? This is poorly documented or it's not possible?

Answer 1

you can define the text attribute in widget definition like that:

<field name="field_with_url" widget="url" readonly="1" text="My own text"/>
