Django-Admin：CharField as TextArea [英] Django-Admin: CharField as TextArea

问题描述

我有

class Cab(models.Model):
    name  = models.CharField( max_length=20 )
    descr = models.CharField( max_length=2000 )

class Cab_Admin(admin.ModelAdmin):
    ordering     = ('name',)
    list_display = ('name','descr', )
    # what to write here to make descr using TextArea?

admin.site.register( Cab, Cab_Admin )

如何分配TextArea小部件到管理界面中的'descr'字段？

how to assign TextArea widget to 'descr' field in admin interface?

upd：

在管理

使用ModelForm的好主意。

Good idea to use ModelForm.

推荐答案

您将必须创建一个 forms.ModelForm ，将描述您希望显示 descr 字段的方式，然后告诉 admin.ModelAdmin 以使用该表单。例如：

You will have to create a forms.ModelForm that will describe how you want the descr field to be displayed, and then tell admin.ModelAdmin to use that form. For example:

from django import forms
class CabModelForm( forms.ModelForm ):
    descr = forms.CharField( widget=forms.Textarea )
    class Meta:
        model = Cab

class Cab_Admin( admin.ModelAdmin ):
    form = CabModelForm

管理员的表单属性。 ModelAdmin 记录在官方Django文档中。以下是一个地方在。

The form attribute of admin.ModelAdmin is documented in the official Django documentation. Here is one place to look at.
