How to disable a button after clicking it in Odoo?

Most of Odoo module use state for this kind of problem. the general idea of it that you must have a field and the button is displayed based on the value of that field.

Ex:

  # in you model
  bool_field = fields.Boolean('Same text', default=False)

In your view:

 <button name="some_method"......... attrs="{'invisible': [('bool_field', '=', True)]}" />
 ...
 ...
 ...
 <!-- keep the field invisible because i don't need the user to see
      it, the value of this field is for technical purpuse -->
 <field name="bool_field" invisible="1"/>

In your model:

 @api.multi
 def some_method(self):
    # in this method i will make sure to change the value of the 
    # field to True so the button is not visible any more for user
    self.bool_field = True
    ...
    ...
    ...

So if you all ready have a field that the button change it's value you can use it directly or create a special field for this purpose.
