在管理员注册django textarea小部件

Question

我想将标准django textarea widget注册为管理员。现在我对此有点困惑，因为在文档中我有ModelAdmin.formfield_overrides的例子，我不想重写它，我只想注册它。 有没有一些简单的方法来做这个注册，或者我应该重写它，并使其自定义的部件吗？

models.py：

from django.db import models 
from django_countries.fields import CountryField 
import datetime 

# Create your models here. 


class ContactForm(models.Model): 
    first_name = models.CharField(max_length=150) 
    last_name = models.CharField(max_length=150) 
    email = models.EmailField(max_length=250) 
    mobile = models.CharField(max_length=32, blank=True) 
    timestamp = models.DateTimeField(default=datetime.datetime.now) 
    birthday = models.DateField(null=True) 
    move_in_date = models.DateField(null=True) 
    move_out_date = models.DateField(null=True) 
    country = CountryField() 

    def __unicode__(self): 
     """TODO: Docstring for __unicode__. 
     :returns: TODO 

     """ 
     return self.email 

    class Meta: 
     ordering = ['-timestamp'] 

forms.py：

from django.forms import ModelForm, extras 
from .models import ContactForm 
from django import forms 
from crispy_forms.helper import FormHelper 
from crispy_forms.layout import Layout 
from crispy_forms.bootstrap import TabHolder, Tab 
from django_countries.widgets import CountrySelectWidget 
import datetime 


def get_move_date_field(): 
    """TODO: Docstring for get_move_date_field. 
    :returns: return a DateField suitable for move_in_date and move_out_date 

    """ 
    return forms.DateField(widget=extras.SelectDateWidget(), initial=datetime.date.today()) 


class ContactView(ModelForm): 

    """TODO: Docstring for ContactView. 
    :returns: ContactView is a class in which we are returning about user information. 
    """ 
    birthday = forms.DateField(widget=extras.SelectDateWidget(years=range(2025, 1939, -1))) 
    move_in_date = get_move_date_field() 
    move_out_date = get_move_date_field() 
    message = forms.CharField(widget=forms.Textarea) 
    helper = FormHelper() 
    helper.form_tag = False 
    helper.layout = Layout(
     TabHolder(
      Tab(
       'Basic Information', 
       'first_name', 
       'last_name', 
       'email', 
       'birthday', 
       'country', 
       'mobile' 
      ), 
      Tab(
       'Moving and additional Information', 
       'move_in_date', 
       'move_out_date', 
       'message', 
      ) 
     ) 
    ) 

    class Meta: 
     fields = ['first_name', 'last_name', 'email', 'mobile', 
        'birthday', 'move_in_date', 'move_out_date', 
        'country', 'message'] 
     model = ContactForm 
     widgets = { 
      'country': CountrySelectWidget() 

}

admin.py：

from django.contrib import admin 
from .models import ContactForm 

# Register your models here. 


class ContactFormAdmin(admin.ModelAdmin): 

    """Docstring for ContactFormAdmin. """ 
    class Meta: 
     model = ContactForm 


admin.site.register(ContactForm, ContactFormAdmin) 

Answer 1

我只是忘了寄存器内消息` models.py”。

消息= models.CharField（MAX_LENGTH = 1000）

后makemigration和migrate我不得不textarea内部django admin。
