Anyone please help me to change a button string dynamically(in tree view)..

I had used fields_view_get but when printing nodes, its empty.. my code is

@api.model
    def fields_view_get(self, view_id=None, view_type='tree', toolbar=False, submenu=False):
        res = super(ClassName, self).fields_view_get(view_id=view_id, view_type=view_type, toolbar=toolbar, submenu=submenu)
        doc = etree.XML(res['arch'])
        nodes = doc.xpath("//buttons"):
        print(nodes)
        return res

At least in V13 (I didn't tried with older releases) you can put a field inside the button, i.e.

<button name="action_todo" icon="fa-edit" type="object"><field readonly="1" name="caption_field" options='{"no_open": True}'></button>

If the caption_field is a many2one field and  you omit the "no_open" option the button will work only clicking on the icon, clicking on the caption will open the related form model.    

The field could also be a computed field so the caption can also change dinamically

I found it the best method, since we don't need to tamper in the '_get_view' method (works in Odoo 17)

Hi, 

I see that you have a ' at the end of buttons. 

In general, you need to specify the path to your button by specifying its name, .. for example : 
doc = etree.XML(res['arch'])

for node in doc.xpath("//button[@name='button_name']"):

        node.set('attrs',  "{'invisible': [.......]}")

        node.set('string',  "........")

        setup_modifiers(node, res['fields'])

 res['arch'] = etree.tostring(doc)


Upvote if this helps.

Regards.

Change .text to .textContent to get/set the text content.

Or since you're dealing with a single text node, use .firstChild.data in the same manner.

Also, let's make sensible use of a variable, and enjoy some code reduction and eliminate redundant DOM selection by caching the result of getElementById.

function toggleText(button_id) 
{
   var el = document.getElementById(button_id);
   if (el.firstChild.data == "Lock") 
   {
       el.firstChild.data = "Unlock";
   }
   else 
   {
     el.firstChild.data = "Lock";
   }
}

Or even more compact like this:

function toggleText(button_id)  {
   var text = document.getElementById(button_id).firstChild;
   text.data = text.data == "Lock" ? "Unlock" : "Lock";
}

The method Odoo uses is to have separate buttons and make them visible and invisible at the appropriate times (either using the "attrs" or "state" tags)

Take a look at how the Invoice buttons work:

<button name="action_invoice_sent" 
        attrs="{'invisible':['|',('sent','=',True), ('state', 'not in', ('open','in_payment','paid'))]}"/>
<button name="148" 
        attrs="{'invisible': [('state', '!=', 'open')]}"/>
<button name="action_invoice_open" states="draft" />
<button name="202" 
        attrs="{'invisible': ['|',('type', '=', 'out_refund'), ('state', 'not in', ('open','in_payment','paid'))]}"/>
<button name="action_invoice_draft" states="cancel"/>

                   

This may or may not be an option for you.
