使用内联格式呈现django-crispy-forms中的字段错误 [英] Rendering field errors in django-crispy-forms with inline forms

问题描述

我使用bootstrap3作为django_crispy_forms中的默认模板包，并尝试使用脆性标签来呈现一个表单：

I'm using bootstrap3 as the default template pack in django_crispy_forms, and trying to render a form with the crispy tag:

{% crispy form %}

我的表单类具有以下帮助器属性：

My form class has the following helper attributes:

class TheForm(forms.Form):
    adv_var = forms.CharField(label="variable", max_length=70)
    value = forms.FloatField()

    def __init__(self, *args, **kwargs):
        super(TheForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper()

        self.helper.form_method = 'post'
        self.helper.form_class = 'form-inline'
        self.helper.field_template = 'bootstrap3/layout/inline_field.html'

        self.helper.layout = Layout(
            'adv_var', 'value',
            ButtonHolder(
                Submit('submit', 'Start', css_class='button white')
            )
        )

当发布表单错误时，重新呈现模板不会显示错误，即使我可以在视图中打印form._errors并查看错误列表。

When posting the form with errors, re-rendering the template does not show the errors even though I can print form._errors in the view and see the list of errors.

如果我将helper.field_template更改为另一个值（或将其删除以设置默认值）错误显示在每个字段之上 - 但是我不再获得内联显示。

If I change the helper.field_template to another value (or remove it to set the default) the errors are displayed above each field - but I don't get the inline display anymore.

如何使用django-crispy-forms来显示此表单的所有错误一个单独的div例如？

How can I use django-crispy-forms to display all errors of this form in a separate div for example?

推荐答案

也许更容易的方法是下一个，因为它使用较少的导入...

Maybe the easier way is the next because it uses less imports...

..在视图中：

if request.method == 'POST':
    form = TheForm(request.POST)
    if form.is_valid():
        form.save()
        return redirect('url_name')
    else:
        form = TheForm()
    return render(request, 'form.html', {'form': form})

...并且您只需要的形式：

... and in the form you need only:

{% load crispy_forms_tags %}
{% crispy form %}

...其中' url_name '是urlpatterns（urls.py）中定义的模式名称...这就是你真正需要的...

... where 'url_name' is defined name of pattern in urlpatterns (urls.py )... that's all you need really...

Crispy是一个非常聪明的系统。系统知道如何直观地显示表单错误。

Crispy is a really smart system. The system knows how can intuitively to show the form errors.
