Django之ModelForm

class CustomerForm(forms.ModelForm):

    def __init__(self,*args,**kwargs):
        super().__init__(*args,**kwargs)
        for field in self.fields.values():
            print(field)
            field.widget.attrs[‘class‘]=‘form-control‘  #给所有字段增加样式
            field.widget.attrs[‘style‘]=‘border-radius: 3px ‘
            # 第二种方法 field.widget.attrs.update({‘class‘:‘form-control‘,‘style‘:‘border-radius: 3px ‘})

    class Meta:
        model = models.Customer
        fields =‘__all__‘

第一种方式 名字判断
        for name,field in self.fields.items():
            if name == ‘course‘:
                continue

第二种方式 类型判断
from multiselectfield import MultiSelectField
通过类型看到是MultiSelectField
    if isinstance(field,(MultiSelectFormField,)):
        continue   

                {% for field in form_obj %}
                  <div class="form-group">
                    <label for="{{ field.id_for_label }}" class="col-sm-3 control-label">{{ field.label }}</label>
                    <div class="col-sm-7">
                        {{ field }}
                        {{ field.errors.0 }}
                    </div>
                  </div>
                {% endfor %}
