Django Inline Admin Formset的额外条目具有前缀而不是数字 [英] Django Inline Admin Formset extra entry has prefix instead of number

问题描述

我有一个管理表单，允许和最终用户添加一个测验，测验有答案。编辑测验时，测验答案部分有4行测验答案。前3个编号为0,1,2，第四个为 __前缀__ 。

示例：

 < input name =quizanswer_set-0 -textvalue =oneclass =vTextFieldmaxlength =255type =textid =id_quizanswer_set-0-text/> 
 
< input id =id_quizanswer_set -__ prefix __- texttype =textclass =vTextFieldname =quizanswer_set -__ prefix __- textmaxlength =255/> 
  

当表单处理时，它跳过第四个输入，因为我假设前缀是不是它正在寻找。

模板代码：

  inline_admin_form inline_admin_formset％的$％
 {{inline_admin_form.pk_field.field}} {{inline_admin_form.fk_field.field}} 
  

形式：

  class QuizAnswerInlineFormSet（forms.models.BaseInlineFormSet）：
 def is_valid （self）：
＃确保错误填充
 _ = self.errors 
 
返回超级（QuizAnswerInlineFormSet，self）.is_valid（）
 
 def clean（self）：
 super（QuizAnswerInlineFormSet，self）.clean（）
 
 answer_count = 0 
 correct_count = 0 
 
 .forms：
如果不是hasattr（form，'clean_data'）：
 continue 
如果不是form.cleaned_data ：
继续
如果不是form.is_valid（）：
继续
如果form.cleaned_data [forms.formsets.DELETION_FIELD_NAME]：
继续
 
 answer_count + = 1 
 
如果form.cleaned_data.get（is_correct，False）：
 correct_count + = 1 
 
如果answer_count< 2：
 raise ValidationError（问题必须至少有2个答案）
 
如果correct_count！= 1：
 raise ValidationError（必须有一个正确答案）有没有人知道为什么会打印 __ PREFIX __ 而不是数字？有没有什么我需要为此设定？我最初没有写这个表单，我只是想解决这个问题，而且我不太熟悉这种形式。
解决方案
我有同样的问题。原来不应该显示该行。当添加新行时，它被用作模板，并且前缀被替换。
 
 
 
我发现我没有拿起表单.css 正确地找不到空格式类的定义，该类具有 display：none 。
 
I have an admin form that allows and end user to add a quiz, and the quiz has answers. When you edit the quiz, the quiz answer section has 4 lines for quiz answers. The first 3 are numbered 0, 1, 2 and the fourth is __prefix__. 

Example:
<input name="quizanswer_set-0-text" value="one" class="vTextField" maxlength="255" type="text" id="id_quizanswer_set-0-text" />

<input id="id_quizanswer_set-__prefix__-text" type="text" class="vTextField" name="quizanswer_set-__prefix__-text" maxlength="255" />
When the form is processed, it skips the fourth input because, I'm assuming, the prefix is not what it is looking for.

Template Code:
{% for inline_admin_form in inline_admin_formset %}
{{ inline_admin_form.pk_field.field }} {{ inline_admin_form.fk_field.field }}
Form:
class QuizAnswerInlineFormSet(forms.models.BaseInlineFormSet):
    def is_valid(self):
        # make sure errors are populated
        _ = self.errors

        return super(QuizAnswerInlineFormSet, self).is_valid()            

    def clean(self):
        super(QuizAnswerInlineFormSet, self).clean()

        answer_count = 0
        correct_count = 0

        for form in self.forms:
            if not hasattr(form, 'cleaned_data'):
                continue
            if not form.cleaned_data:
                continue
            if not form.is_valid():
                continue
            if form.cleaned_data[forms.formsets.DELETION_FIELD_NAME]:
                continue

            answer_count += 1

            if form.cleaned_data.get("is_correct", False):
                correct_count += 1

        if answer_count < 2:
            raise ValidationError("Questions must have at least 2 answers")

        if correct_count != 1:
            raise ValidationError("There must be exactly one correct answer")
Does anyone have an idea of why this would be printing __PREFIX__ rather than a number? Is there something I need to set for this? I didn't originally make the form, I'm just trying to fix it and I'm not overly familiar with this type of form.
解决方案
I had the same issue. It turns out that row shouldn't be displayed. It is used as a template by the javascript when adding new rows and the prefix is replaced.

I found that I wasn't picking up forms.css properly so it couldn't find the definition for the empty-form class which has display: none.
