The Many2many records is listed in a tree view. How do you propose I add a button there? And with what attributes? Do you have an example?

suppose your field is x_ids.

in Xml add context like this :

<field name="x_ids"

context="{'tree_view_ref':'your_model.your_tree_view_to_display_in_x_ids'}"/>

Then declare the tree view :

<record model="ir.ui.view" id="your_tree_view_to_display_in_x_ids">

<field name="name">your.tree.view.to.display.in.x.ids</field>

<field name="model">your.model</field>

<field name="priority">500</field>

<field name="arch" type="xml">

<tree readonly="1">

<field name="Field1"/>

<field name="Field2"/>

<field name="Field3"/>

<field name="Field4"/>

<field name="Field5"/>

<button name="button_redirect_to_record" type="object" icon="fa-archive"

string="Open Record"/>

</tree>

</field>

</record>

Now Your button function should be like this :

@api.multi

def button_redirect_to_record(self):

self.ensure_one()

return {

'name': _('Model'),

'view_type': 'form',

'view_mode': 'form',

'view_id': self.env.ref('Your_model.Your_Form_View').id,

'res_model': 'your.model',

'context': self._context,

'type': 'ir.actions.act_window',

'nodestroy': True,

'target': 'current',

'res_id': your_record_id,

}

Let me know the output in your case.

Hope this will help you.

Thanks guys for you help. Actually I was more hoping there was an option for the m2m widget that could do this. Even adding a button feels like a hack in the user interface for the user since clicking the whole row still opens the dialog. I'm gonna research how to extend the widget and change the behaviour there

Im also hoping someone can answer the second part of the question 2)
