Python 覆盖Django中不带模型的Textarea。仅在形式上

我想更改Textarea的默认大小。我读到： [ 但我不知道我怎么能推翻它

我的代码： forms.py：

from django import forms 

class KarForm(forms.Form):
    message = forms.CharField(
        widget=forms.Textarea,
        label="",
    )

views.py：

from django.shortcuts import render
from .forms import KarelForm

def home(request):
    form = KarForm()
    context = {
    "form": form
    }
    return render(request, "form.html", context)

选中。您可以添加类或其他属性，例如：

class CommentForm(forms.Form):
    name = forms.CharField(widget=forms.TextInput(attrs={'class': 'special'})) # then you define the class in your css file
    url = forms.URLField()
    comment = forms.CharField(widget=forms.TextInput(attrs={'size': '40'}))

选中。您可以添加类或其他属性，例如：

class CommentForm(forms.Form):
    name = forms.CharField(widget=forms.TextInput(attrs={'class': 'special'})) # then you define the class in your css file
    url = forms.URLField()
    comment = forms.CharField(widget=forms.TextInput(attrs={'size': '40'}))
