display readonly or not

[Tony Peña]

hi

i have this on my model.admin

class MyDomainAdmin(admin.ModelAdmin):

    list_display = ('domain', 'enabled', 'avscan', 'spamassassin', 'max_accounts')

    list_filter = ('enabled',)

    exclude = ('uid', 'gid', 'maildir')

# this part is my pseudo-code logic I want but i can't solved.

    if not user.is_superuser

        readonly_fields = ('max_accounts',)

how can i set readonly for users staff? but normally modify for only superusers?

There is a get_read_only() method in the admin.ModelAdmin class. It
normally returns self.readonly_fields but you can give it a callable.

https://docs.djangoproject.com/en/1.8/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_readonly_fields

As well as defining any readonly fields (for everyone) you want
something like ...

def ro_fields(self, request, obj=None):
if obj is None or request.user.is_superuser:
return self.readonly_fields
else:
return self.model._meta.get_all_field_names()

... then get_readonly_fields = ro_fields should make it happen like your
pseudocode.

hmmm.. not work

the field max_account must be modify for superuser not for the staff.

class VeximDomainAdmin(admin.ModelAdmin):

    list_display = ('domain', 'enabled', 'avscan', 'spamassassin', 'max_accounts')

    list_filter = ('enabled',)

    exclude = ('uid', 'gid', 'pipe', 'maildir', 'blocklists', 'complexpass')

    readonly_fields = ('max_accounts',)

    def ro_fields(self, request, obj=None):

        if obj is None or request.user.is_superuser:

            return self.readonly_fields

        else:

            return self.model._meta.get_all_field_names()

    get_readonly_fields = ro_fields

Why do you define a separate method, then alias to get_readonly_fields? Why not override the method directly?

Because in some places/models in the admin I don't want to override the
method; and in all (my) cases there needs to be readonly "modified" and
"modified_by" fields for superusers as well.

Further, I put my ro_fields method in a common module and import it
where required in a number of apps in that project.

Cheers

Mike
