Django表单字段未显示在模板中-为什么? [英] django form fields are not showing up in template - why?

问题描述

文档说，要在模板中显示表单字段，我需要这样做:

The Docs says, to display the form fields in template, i need to do this:

<form action="/search_for_book/">{% csrf_token %}
   {{form.as_p}}
   <input type="submit" value="Suchen" />
</form>

我做到了.这是我的看法.

i did this. and this is my views.

def addbook(request):
   form = AddBook()
   return render(request,'searchbook.html',{'form':form})

这是我的表格.在forms.py中定义并导入到views.py

this is my form. defined in forms.py and imported into views.py

class AddBook(forms.Form):
   titel = forms.TextInput()
   author = forms.TextInput()

为什么表单字段没有显示在模板中?我几乎从文档中复制了1:1.模板仅显示按钮追求n ，没有其他内容.Docs没有谈论Urlconf，我也必须这样做吗?

why dont Form fields show up in template? I did almost the 1:1 copy from docs. Template shows only the button Suchen and nothing else. Docs doesnot say anything about Urlconf, do i have to do also?

推荐答案

之所以这样，是因为您要定义一个小部件，而该小部件只是HTML输入元素的一种表示形式，而不是在forms.py中定义一个字段.

请执行以下操作:

The reason why is that you're defining a widget, which is merely a representation of a HTML input element, instead of defining a field in your forms.py

Do the following:

class AddBook(forms.Form):
    titel = forms.CharField(widget=forms.TextInput())
    author = forms.CharField(widget=forms.TextInput())

PS:不要怪Django的文档-它们真的很棒！

有关小部件的参考，请在此处阅读: https://docs.djangoproject.com/en/dev/ref/forms/widgets/
有关字段的参考，请在此处阅读: https://docs.djangoproject.com/en/dev/ref/forms/fields/

PS: don't blame django's docs - they are really excellent!

For the reference on fields, read here: https://docs.djangoproject.com/en/dev/ref/forms/fields/
