Hi, I have a couple of questions for the list, I hope someone can help me.
I have a model like:
class ClientElement(models.Model):
client_code = models.CharField(max_length = 10,
default = get_client_code,
editable = True,
blank = False)
name = models.CharField(
max_length = 255,
blank = False)
class Admin:
pass
when editing this model in the administrative interface, the
get_client_code() function automatically fills the default value for
field 'client_code' depending on a dynamic condition (when
get_client_code() is not null).
I would like to hide this field (set editable = False) when that
condition is true, something like:
client_code = models.CharField(max_length = 10,
default = get_client_code,
editable = client_code_is_null,
blank = False)
where client_code_is_null would return True or False. However, this is
evaluated just once, when parsing the models.
¿Is it possible to delay this evaluation until rendering the
administrative interface?
Second, I'd like to change list_display dynamically too, For example:
class ClientElement(models.Model):
client_code = models.CharField(max_length = 10,
default = get_client_code,
editable = True,
blank = False)
name = models.CharField(
max_length = 255,
blank = False)
class Admin:
list_display = ['client_code', 'name']
but I want list_display to be just:
class Admin:
list_display = ['name']
Again, when certain condition is met (depending on the client_code
from the current user profile) I want the administrative interface to
hide column 'client_code'.
I found a workaround for this in here:

I just wonder if there exists a better and cleaner way of doing this.
Thanks very much!
