Hi, I'm trying to become invisible a button when the current date is not the same as the date of a field, I mean I need to show the button only when the current date will be the same as the date of a field.

I'm trying to use to do this in the xml the context_today () but I could not do it, my syntax for hidden button is:

attrs = "{'invisible': [('f_inicio', '!=', ((context_today ()). strftime ('%% Y-%% m-%% d')))]}"

The error message I get is "NameError: name 'context_today' is not defined".

I tried also with the following code:

attrs = "{'invisible': [('f_inicio', '!=', __import__ ('time'). strftime ('%% Y-%% m-%% d'))]}"

With the latter does not give me errors but does not do what is required, hide the button when the f_inicio not equal to the current date.

If I can lend a hand is the greatly appreciate,

Note: The "f_inicio" is of type "datetime" and the button I want to hide this placing in the section "header" of the view.
