Thank you Tom. Somehow it seemed strange to test this view using client.get('/page/', { 'filter': 'one and two'}) but I get why it is like this. Cheers, Eneko On Monday, April 20, 2015 at 3:30:55 PM UTC+2, Tom Evans wrote: > > On Sat, Apr 18, 2015 at 12:13 PM, Eneko Illarramendi >

Choices in DecimalField - django 1.8.

In the model below, using the Django admin, no matter what value I choose, it always displays the default value. But writes the correct value in the database. Am I doing something wrong or is this a bug? TENSAO_220 = Decimal(220) TENSAO_110 = Decimal(110) TENSOES = ((TENSAO_220, '220 volts'),

I did a little research on this and found cpulimit, you can also use nice and renice, and (on fedora core 21 at least) you can do 'cat /proc/###/status’ where ### is the process ID which will give you memory stats on a process. Not ideal but you can wrap all of these in some python to make it

Choices as a callable.. but no parameters?

I am trying to build a form with dynamic choices. e.g., the choices should depend on the user. https://docs.djangoproject.com/en/1.8/ref/forms/fields/#choicefield Says choices may now be a callable, and sure enough it is called in ` django/forms/fields.py(818)` – but without any parameters.

Re: Choices as a callable.. but no parameters?

Overwrite the constructor of the form (__init__), pass the user or whatever parameters you may need and overwrite the choices of the field in the body of the method. On Mon, Apr 20, 2015 at 10:56 PM, Steve Hiemstra wrote: > I am trying to build a form with dynamic choices.
