（Django）从charField修剪空格

Question

如何在Django中charField的末尾去除空格（trim）？

这是我的模型，如您所见，我已经尝试过使用干净的方法，但是这些方法永远不会运行。

我也尝试过这样做name.strip()，models.charField().strip()但是这些也不起作用。

有没有办法强制为我自动修剪charField？

谢谢。

from django.db import models
from django.forms import ModelForm
from django.core.exceptions import ValidationError
import datetime

class Employee(models.Model):
    """(Workers, Staff, etc)"""
    name                = models.CharField(blank=True, null=True, max_length=100)

    def save(self, *args, **kwargs):
        try:
            # This line doesn't do anything??
            #self.full_clean()
            Employee.clean(self)
        except ValidationError, e:
            print e.message_dict

        super(Employee, self).save(*args, **kwargs) # Real save

    # If I uncomment this, I get an TypeError: unsubscriptable object
    #def clean(self):
    #   return self.clean['name'].strip()

    def __unicode__(self):
        return self.name

    class Meta:
        verbose_name_plural = 'Employees'

    class Admin:pass


class EmployeeForm(ModelForm):
    class Meta:
        model = Employee

    # I have no idea if this method is being called or not  
    def full_clean(self):       
        return super(Employee), self.clean().strip()
        #return self.clean['name'].strip()

编辑：将代码更新为我的最新版本。我不确定我在做什么错，因为它仍然没有剥离空白（修剪）名称字段。

必须调用模型清洗（这不是自动的），因此请self.full_clean()在保存方法中放置一些模型清洗。
http://docs.djangoproject.com/en/dev/ref/models/instances/#django.db.models.Model.full_clean

对于您的表单，您需要返回剥离后的清理数据。

return self.cleaned_data['name'].strip()

我以某种方式认为您只是尝试做一堆行不通的事情。请记住，表单和模型是两件截然不同的东西。

super(Employee), self.clean().strip() makes no sense at all!

这是您的固定代码：

class Employee(models.Model):
    """(Workers, Staff, etc)"""
    name = models.CharField(blank=True, null=True, max_length=100)

    def save(self, *args, **kwargs):
        self.full_clean() # performs regular validation then clean()
        super(Employee, self).save(*args, **kwargs)


    def clean(self):
        """
        Custom validation (read docs)
        PS: why do you have null=True on charfield? 
        we could avoid the check for name
        """
        if self.name: 
            self.name = self.name.strip()


class EmployeeForm(ModelForm):
    class Meta:
        model = Employee


    def clean_name(self):
        """
        If somebody enters into this form ' hello ', 
        the extra whitespace will be stripped.
        """
        return self.cleaned_data.get('name', '').strip()
