MVC4：SQL登录失败。(MVC4: SQL Login failed. Error code 1. Only happening on one page)

 您还可以创建自定义模型字段类型 - 请参阅http://docs.djangoproject.com/en/dev/howto/custom-model-fields/#howto-custom-model-fields 
 
 在这种情况下，您可以从内置的IntegerField继承，并覆盖其验证逻辑。 
 
 我想到的越多，我就意识到对于许多Django应用程序来说，这有多有用。 也许一个IntegerRangeField类型可以作为Django开发人员考虑添加到trunk的补丁来提交。 
 
 这是为我工作： 
 
from django.db import models

class IntegerRangeField(models.IntegerField):
    def __init__(self, verbose_name=None, name=None, min_value=None, max_value=None, **kwargs):
        self.min_value, self.max_value = min_value, max_value
        models.IntegerField.__init__(self, verbose_name, name, **kwargs)
    def formfield(self, **kwargs):
        defaults = {'min_value': self.min_value, 'max_value':self.max_value}
        defaults.update(kwargs)
        return super(IntegerRangeField, self).formfield(**defaults)
 
 然后在你的模型类中，你可以像这样使用它（字段是放在上面的代码的模块）： 
 
size = fields.IntegerRangeField(min_value=1, max_value=50)
 
 或一个负和正的范围（如振荡器范围）： 
 
size = fields.IntegerRangeField(min_value=-100, max_value=100)
 
 真的很酷的是如果可以用这样的范围操作符来调用它： 
 
size = fields.IntegerRangeField(range(1, 50))
 
 但是，这将需要更多的代码，因为您可以指定“skip”参数 - 范围（1，50，2） - 有趣的想法，但... 

You could also create a custom model field type - see http://docs.djangoproject.com/en/dev/howto/custom-model-fields/#howto-custom-model-fields
 
In this case, you could 'inherit' from the built-in IntegerField and override its validation logic.
 
The more I think about this, I realize how useful this would be for many Django apps. Perhaps a IntegerRangeField type could be submitted as a patch for the Django devs to consider adding to trunk.
 
This is working for me:
 
from django.db import models

class IntegerRangeField(models.IntegerField):
    def __init__(self, verbose_name=None, name=None, min_value=None, max_value=None, **kwargs):
        self.min_value, self.max_value = min_value, max_value
        models.IntegerField.__init__(self, verbose_name, name, **kwargs)
    def formfield(self, **kwargs):
        defaults = {'min_value': self.min_value, 'max_value':self.max_value}
        defaults.update(kwargs)
        return super(IntegerRangeField, self).formfield(**defaults)
 
Then in your model class, you would use it like this (field being the module where you put the above code):
 
size = fields.IntegerRangeField(min_value=1, max_value=50)
 
OR for a range of negative and positive (like an oscillator range):
 
size = fields.IntegerRangeField(min_value=-100, max_value=100)
 
What would be really cool is if it could be called with the range operator like this:
 
size = fields.IntegerRangeField(range(1, 50))
 
But, that would require a lot more code since since you can specify a 'skip' parameter - range(1, 50, 2) - Interesting idea though...
