• [Django] How do I filter the choices in a ModelForm that has a CharField with the choices attribute

  - by nubela

  I understand I am able to filter queryset of Foreignkey or Many2ManyFields, however, how do I do that for a simple CharField that is a Select Widget (Select Tag). For example: PRODUCT_STATUS = ( ("unapproved", "Unapproved"), ("approved", "Listed"), #("Backorder","Backorder"), #("oos","Out of Stock"), #("preorder","Preorder"), ("userdisabled", "User Disabled"), ("disapproved", "Disapproved by admin"), ) and the Field: o_status = models.CharField(max_length=100, choices=PRODUCT_STATUS, verbose_name="Product Status", default="approved") Suppose I wish to limit it to just "approved" and "userdisabled" instead showing the full array (which is what I want to show in the admin), how do I do it? Thanks!

• how can i introspect properties and model fields in django?

  - by shreddd

  I am trying to get a list of all existing model fields and properties for a given object. Is there a clean way to instrospect an object so that I can get a dict of fields and properties. class MyModel(Model) url = models.TextField() def _get_location(self): return "%s/jobs/%d"%(url, self.id) location = property(_get_location) What I want is something that returns a dict that looks like this: { 'id' : 1, 'url':'http://foo', 'location' : 'http://foo/jobs/1' } I can use model._meta.fields to get the model fields, but this doesn't give me things that are properties but not real DB fields.

• Is there going to be a friendly Unity settings window?

  - by Valorin

  Currently, as far as I am aware, you need to use the CompizConfig Settings Manager application to play with the Unity configuration settings. While this makes sense, from a technical point of view, it requires the user to know about the settings manager, install it, and then find the Unity options within it. Not very user friendly. Is there a user friendly configuration application planned that will offer all the configuration options in an easy-to-use for new people fashion?
