如何覆盖 django 中的password_change错误消息?
我花了很长时间在网上如何覆盖 django 中的change_password 表单。我创建了表单,并且可以成功更改密码。现在我想在页面上显示我的错误。 (顺便说一句,我正在使用 django-registration。)
问题是我必须更改错误消息。在我的模板中,我使用此函数来显示 new_password1 错误:
{% if form.new_password1.errors %}
<div class="error_message"> blah </div>
{% endif %}
但是它包含所有 new_password1 错误。我查看了文档,发现 CharField 仅需要 max 和 min。我需要检查 new_password1 的每个特定错误(确认错误、必需错误和最小值、最大值)并生成我自己的错误消息。由于 CharField 没有匹配的关键字,我在 forms.py 中尝试了一个干净的方法,如下所示:
def clean_password2(self):
if 'new_password1' in self.cleaned_data and 'new_password2' in self.cleaned_data:
if self.cleaned_data['new_password1'] != self.cleaned_data['new_password2']:
raise forms.ValidationError(_(u"no match"))
return cleaned_data
最后,我不知道如何在模板中检查 clean_password2 验证。当我编写注册页面时,我可以通过循环错误来显示我的所有错误。它显示所有被覆盖的错误。这次不行了。所以我的问题是:
1-如何检查模板中的所有特定错误?就像 if form.new_password1.required.errors
2-我如何显示此 clean_password2 消息?
I have spent ages on the net how to override the change_password form in django. I created my forms and I can change my passwords successfully. Now I want to display my errors on the page.
(By the way , I'm using django-registration.)
The problem is I have to change error messages. In my template I'm using this function to display new_password1 errors :
{% if form.new_password1.errors %}
<div class="error_message"> blah </div>
{% endif %}
However it consists of all new_password1 errrors. I looked the docs and found that CharField has only reqiured, max and min. I need to check each specific errors of the new_password1 (confirmation error, required error and min,max) and produce my own error messages. Since the CharField doesn't have a matching keyword, I tried a clean method in my forms.py which looks like :
def clean_password2(self):
if 'new_password1' in self.cleaned_data and 'new_password2' in self.cleaned_data:
if self.cleaned_data['new_password1'] != self.cleaned_data['new_password2']:
raise forms.ValidationError(_(u"no match"))
return cleaned_data
Finally, I don't know how to check this clean_password2 validation in my template. When I wrote registration page, I can display all my errors by looping the errors. And it displays all overrided errors. This time it doesn't work. So my quesstions are:
1- How can i check all specific errors in my templates ? like if form.new_password1.required.errors
2- How can i display this clean_password2 messages ?

在 django 语言中,您所指的视图就是模板。真是比较混乱啊!
更新:我看到您定义了一个
clean_password2
函数,但您正在检查名为new_password1
、new_password2
的字段。除非您有一个名为
password2
的字段,否则 that 就是您的 clean 方法正在验证的字段。clean_password2
的消息是在{{ form.password2.errors }}
中生成的,但对我来说,听起来您没有名为password2 的字段
。将方法名称更改为
clean_new_password2
。表单字段清理按字段进行。您可以访问字段对象的错误。
In django-speak, what you're referring to as the view is the template. It's rather confusing!
Update: I see that you define a
clean_password2
function but you are checking for fields callednew_password1
,new_password2
.Unless you have a field called
password2
, that is the field that your clean method is validating.The messages for
clean_password2
are generated in{{ form.password2.errors }}
, but to me, it sounds like you don't have a field calledpassword2
.Change the name of your method to
clean_new_password2
.Form field cleaning works per field.. you access the errors off the field object.
就像@Yuji所说,在模板中使用
{% if form.non_field_errors %}
。现在简单介绍一下可用性。关于用户注册和密码更改表单,您可以预期的唯一非字段错误将是密码不匹配,因此与您要在一开始打印非字段错误的其他表单不同,对于这些表单,打印是有意义的两个密码输入字段之前的一个非字段错误,可能将它们包装在具有红色背景的父字段中,以便更明显地表明这两个字段的值是相关的,并且错误涉及这两个字段,而不是形式一般。
Like @Yuji said, use
{% if form.non_field_errors %}
in your template.Now just a bit on usability. Concerning the user registration and password change form, the only non-field errors your can expect will be mismatching passwords, so unlike other forms where your going to print the non-field errors at the very beginning, for these forms it makes sense to print the one non-field error before the two password input fields, possibly wrapping them in a parent that has a red background, to make it more obvious that the values of the two fields are related and that the error concerns the two fields, not the form in general.
