Question

我有CRUD视图，其中一个看起来像这样：

#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？

Answer 1

您需要创建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。在任何一种情况下，您都需要创建自定义Form并告诉您的View使用该表单：

<强> 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 views.py ：

中

from myapp.forms import FooForm

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

Answer 2

如果要执行此操作，则必须明确定义表单。

class Model1Form(forms.ModelForm):
    field1 = forms.CharField(widget=forms.TextInput(attrs={'class': 'myclass'}))
    class Meta:
        model = Model1
        fields = ['field1', 'field2']

class Model1CreateView(CreateView):
    form_class = Model1Form
    model = Model1

为通用表单的字段指定css类
