Helloooooooooooooooooooooooo there!

Admit that we are march 7th.

I want a filter who accepts only date of the current month and the last month.

So I want a filter who accepts date from february 1st to march 31th (but I won't have document dated after the march 7th).

Is my filter ok?

XML filter :

<filter string="Current and last months" name="currentandlastmonths" 
domain="[
('date','&gt;=',(context_today()-relativedelta(months=1)).strftime('%Y-%m-01')),
('date','&lt;',(context_today()+relativedelta(months=1)).strftime('%Y-%m-01'))
]" />

Edit #1

Interesting link to learn about this kind of filter. Many examples there :
