python - 为通用表单的字段指定 css 类

Question

我有 CRUD View ，其中之一如下所示:

#model
class Model(models.Model):
    field1 = models.CharField()
    field2 = models.CharField()



#view
class Model1CreateView(CreateView):
    model = Model1
    fields = ['field1', 'field2']

#template
and model1_form.html

    <form action="{% url 'model1_new' %}" method="post">
      {% csrf_token %}
      {{ form.as_p }}
      <input type="submit" value="Submit" />
    </form>

我需要为field1指定一个css类，我该怎么做？

您需要创建一个Form并修改该字段小部件的attrs。有两种常见的方法可以做到这一点。无论哪种情况，您都需要创建一个自定义 Form 并告诉您的 View 使用该表单:

forms.py

from django import forms
from myapp.models import FooModel

class FooForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(FooForm, self).__init__(*args, **kwargs)
        self.fields['field1'].widget.attrs = { 'class': 'fooclass' }

    class Meta:
        model = FooModel
        fields = ['field1', 'field2']

或

from django import forms
from myapp.models import FooModel

class FooForm(forms.ModelForm):
    field1 = forms.CharField(widget=forms.Textarea(attrs={'class':'fooclass';}))

    class Meta:
        model = FooModel
        fields = ['field1', 'field2']

然后在您的views.py中:

from myapp.forms import FooForm

class Model1CreateView(CreateView):
    model = Model1
    fields = ['field1', 'field2']
    form_class = FooForm
