Even though a field is marked as 'editable=False'
in the model, I would like the admin page to display it. Currently it hides the field altogether.. How can this be achieved ?
即使一个字段在模型中被标记为“editable=False”,我还是希望管理页面显示它。目前它完全隐藏了这个领域。如何实现这一点?

Use Readonly Fields. Like so (for django >= 1.2):
使用只读的字段。(对于django >= 1.2):
class MyModelAdmin(admin.ModelAdmin):
readonly_fields=('first',)

This solution is useful if you want to keep the field editable in Admin but non-editable everywhere else. If you want to keep the field non-editable throughout then @Till Backhaus' answer is the better option.
如果您希望在Admin中保持字段可编辑,但在其他任何地方都不可编辑,那么这个解决方案是非常有用的。如果你想让整个字段不可编辑,那么@Till Backhaus的答案是更好的选择。

One way to do this would be to use a custom ModelForm
in admin. This form can override the required field to make it editable. Thereby you retain editable=False
everywhere else but Admin. For e.g. (tested with Django 1.2.3)
一种方法是在admin中使用自定义的ModelForm。此表单可以覆盖所需字段,使其可编辑。因此,除了Admin之外,其他地方都保留editable=False。例如(用Django 1.2.3测试)
# models.py
class FooModel(models.Model):
first = models.CharField(max_length = 255, editable = False)
second = models.CharField(max_length = 255)
def __unicode__(self):
return "{0} {1}".format(self.first, self.second)
# admin.py
class CustomFooForm(forms.ModelForm):
first = forms.CharField()
class Meta:
model = FooModel
fields = ('second',)
class FooAdmin(admin.ModelAdmin):
form = CustomFooForm
admin.site.register(FooModel, FooAdmin)
