Disable Form Validation on button click Odoo13

Question

In my form view I have added a simple button of type object-
<button name="select_call_api" string="select" type="object"/> And in my python model file I have added the function call-
def select_call_api(self):
print("select_call_api called")
But on button click it's by default doing *form validation*. Like if there are any mandatory fields and
they are not filled, then it's throwing "*The following fields are invalid*:" Error.
How do I disable or skip the *form validation*?

Hello,

I am not sure this is still needed but I have found a way.

This has been tested with Odoo 10.

I have found that using the `special` attribute allowed you to bypass validation.
Also, no validation is made on the value of the special attribute and only the value `cancel` is used to cancel.
Define your button this way:

name="abort"
string="Abort"
type="object"
class="btn btn-default"
special="[ANYTHING BUT NOT cancel]"

and it will disable form validation, will not trigger `create` or `w

There is no way because odoo framework architecture designed that way. when you click on the button framework try to create a new record and it will check all the required fields.
A workaround is checking form validation on fields onchange it didn't require to create a record first. however, all the fields value get on the server-side.
