从Django UserCreateForm中删除help_text [英] Removing help_text from Django UserCreateForm

问题描述

可能是一个糟糕的问题，但是我使用Django的UserCreationForm（稍微修改为包含电子邮件），我想删除Django自动显示在HTML页面上的help_text。

在我的HTML页面的注册部分，它有用户名，电子邮件，密码1和密码2个字段。但是用户名是必填的，只有30个字符或更少的字母，数字和@ ...。并且在密码确认（密码2）下，它说输入与上述相同的密码进行验证。

如何删除这些？

 ＃models.py 
 class UserCreateForm（UserCreationForm）：
 email = forms.EmailField（required = True）
 
 def save（self，commit = True）：
 user = super（UserCreateForm ，self）.save（commit = False）
 user.email = self.cleaned_data ['email'] 
如果提交：
 user.save（）
返回用户
 
 class Meta：
 model = User 
 fields =（username，email，password1，password2）
 exclude =（'username.help_text '）
 
＃views.py 
 def index（request）：
r = Movie.objects.all（）。order_by（' -  pub_date'）
 form = UserCreateForm（）
返回render_to_response（'qanda / index.html'，{'latest_movie_list'：r，'form'：form}，context_instance = RequestContext（request））
 
 #index。 html 
< form action =/ home / register /method =postid =register> {％csrf_token％} 
< h6>创建一个帐户< / h6> 
 {{form.as_p}} 
< input type =submitvalue =Create！> 
< input type =hiddenname =nextvalue ={{next | escape}}/> 
< / form> 
  

解决方案

您可以设置 help_text 字段为无 __ init __

  from django.contrib.auth.forms import django import UserCreationForm 
 
 
 class UserCreateForm（UserCreationForm）：
 email = forms.EmailField（required = True）
 
 def __init __（self，* args，** kwargs）：
 super（UserCreateForm，self）.__ init __（* args，** kwargs）
 
 for [ '，'password1'，'password2']：
 self.fields [fieldname] .help_text = None 
 
打印UserCreateForm（）
  pre> 
 
 
输出：
 < tr>< th> < label for =id_username>用户名：< / label>< / th>< td>< input id =id_usernametype =textname =usernamemaxlength =30/ >< / TD>< / TR> 
< tr>< th>< label for =id_password1>密码：< / label>< / th>< td>< input type =passwordname =password1 id =id_password1/>< / td>< / tr> 
< tr>< th>< label for =id_password2>密码确认：< / label>< / th>< td>< input type =passwordname = password2id =id_password2/>< / td>< / tr> 
< tr>< th>< label for =id_email>电子邮件：< / label>< / th>< td>< input type =textname =email id =id_email/>< / td>< / tr> 
  
如果您做了太多更改，在这种情况下，最好只是覆盖字段，例如
  class UserCreateForm（UserCreationForm）：
 password2 = forms.CharField（label = _（Whatever），widget = MyPasswordInput 
  
但在您的情况下，我的解决方案将会很好地运作。
 
Probably a poor question, but I'm using Django's UserCreationForm (slightly modified to include email), and I would like to remove the help_text that Django automatically displays on the HTML page. 

On the Register portion of my HTML page, it has the Username, Email, Password1 & Password 2 fields. But underneath Username is "Required. 30 characters or fewer. Letters, digits, and @... only." And under Password Confirmation (Password 2), it says "Enter the same password as above for verification." 

How do I remove these?
#models.py
class UserCreateForm(UserCreationForm):
    email = forms.EmailField(required=True)

    def save(self, commit=True):
        user = super(UserCreateForm, self).save(commit=False)
        user.email = self.cleaned_data['email']
        if commit:
            user.save()
        return user

    class Meta:
        model = User
        fields = ("username", "email", "password1", "password2")
        exclude = ('username.help_text')

#views.py
def index(request):
    r = Movie.objects.all().order_by('-pub_date')
    form = UserCreateForm()
    return render_to_response('qanda/index.html', {'latest_movie_list': r, 'form':form},     context_instance = RequestContext(request))

#index.html
<form action = "/home/register/" method = "post" id = "register">{% csrf_token %}
    <h6> Create an account </h6>
    {{ form.as_p }}
    <input type = "submit" value = "Create!">
    <input type = "hidden" name = "next" value = "{{ next|escape }}" />
</form>

解决方案
You can set help_text of fields to None in __init__
from django.contrib.auth.forms import UserCreationForm
from django import forms

class UserCreateForm(UserCreationForm):
    email = forms.EmailField(required=True)

    def __init__(self, *args, **kwargs):
        super(UserCreateForm, self).__init__(*args, **kwargs)

        for fieldname in ['username', 'password1', 'password2']:
            self.fields[fieldname].help_text = None

print UserCreateForm()
output:
<tr><th><label for="id_username">Username:</label></th><td><input id="id_username" type="text" name="username" maxlength="30" /></td></tr>
<tr><th><label for="id_password1">Password:</label></th><td><input type="password" name="password1" id="id_password1" /></td></tr>
<tr><th><label for="id_password2">Password confirmation:</label></th><td><input type="password" name="password2" id="id_password2" /></td></tr>
<tr><th><label for="id_email">Email:</label></th><td><input type="text" name="email" id="id_email" /></td></tr>
If you are doing too many changes, in such cases it is better to just override the fields e.g.
class UserCreateForm(UserCreationForm):
    password2 = forms.CharField(label=_("Whatever"), widget=MyPasswordInput 
but in your case my solution will work very well.
