xml - OpenERP How to make a button invisible when datetime field != date today -

in python, have next field:

'transaction_date': fields.datetime('transaction date')

in xml, have following:

<field name="transaction_date" readonly="true" /> <button name="set_void" string="void" type="object" icon="gtk-cancel" groups="mymodule.mygroup" attrs="{'invisible':[('transaction_date','!=', datetime.now())]}" />

the attrs code above doesn't work want is: able show "void" button when transaction_date field's date value = today. possible?

if using v7, seek attrs:

attrs="{'invisible':[('transaction_date','!=',__import__('time').strftime('%%y-%%m-%%d %%h:%%m:%%s'))]}"

if using v6 or v6.1, seek attrs:

attrs="{'invisible':[('transaction_date','!=',time.strftime('%%y-%%m-%%d %%h:%%m:%%s'))]}"

i suggest you should usefields.date instead of fields.datetime because field not visible in datetime format because whenever select date & time, seconds not match.

if utilize fields.date utilize time.strftime('%%y-%%m-%%d') in attrs.

thank you.
