我有一個管理員表單允許和最終用戶添加測驗,並且測驗有答案。當您編輯測驗時,測驗答案部分有4行測驗答案。前3個編號爲0,1,2,第四個編號爲__prefix__Django Inline Admin Formset額外條目有前綴而不是數字

例子:

<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" /> 

當表單處理,它會跳過第四輸入,因爲,我假設,前綴是不是它正在尋找。

模板代碼:

{% for inline_admin_form in inline_admin_formset %} 
{{ inline_admin_form.pk_field.field }} {{ inline_admin_form.fk_field.field }} 

形式:

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") 

沒有人有爲什麼會被打印__PREFIX__,而不是數量的想法?有什麼我需要爲此設置?我本來沒有製作表格,我只是想解決這個問題,而且我不太熟悉這種形式。

我有同樣的問題。事實證明,行不應該顯示。當添加新行並替換前綴時,它被javascript用作模板。

我發現我沒有正確撿起forms.css,所以找不到empty-form類的定義,它有display: none
