Question

用户提交的表单中的数据验证失败后， form.errors 实际上会收集这些错误，因为我一直在调试问题。但是，当我在POST请求后呈现页面时，错误不会在出现错误的字段旁边解析为HTML。

换句话说，import java.util.Scanner; public class Game { public static void main(String[] args) throws InterruptedException { String com = "Computer: "; System.out.print(com +"H"); Thread.sleep(75); System.out.print("i"); Thread.sleep(75); System.out.println("."); Thread.sleep(2000);不会在html中呈现。

当用户数据未通过验证时，为了使验证错误在模板中呈现，需要进行哪些更改？

<ul class="errorlist">

# view that renders the template

@login_required(login_url="/accounts/sign_in/")
def new_profile(request, username):
    form = ProfileForm()
    import pdb; pdb.set_trace()
    if request.method == 'POST':
        user_profile = ProfileForm(request.POST)
        if user_profile.is_valid():
            user_profile.cleaned_data.update(user=request.user)
            Profile.objects.create(**user_profile.cleaned_data)
            return HttpResponseRedirect(
                reverse("accounts:profile", kwargs={'username': username})
            )
    return render(request, 'accounts/create_profile.html', {'form': form})

# create_profile.html

{% extends 'layout.html' %}
{% block body %}
    <form action="{% url 'accounts:new_profile' username=user %}" method="post">
        {% csrf_token %}
        {{ form }}
        <button type="submit">Submit</button>
    </form>  
{% endblock %}

如果该表单无效，则将其提供给用户。

else:
    form = ProfileForm()


@login_required(login_url="/accounts/sign_in/")
def new_profile(request, username):
    import pdb; pdb.set_trace()
    if request.method == 'POST':
        form = ProfileForm(request.POST)
        if form.is_valid():
            form.cleaned_data.update(user=request.user)
            Profile.objects.create(**form.cleaned_data)
            return HttpResponseRedirect(
                reverse("accounts:profile", kwargs={'username': username})
            )
    else:
        form = ProfileForm()
    return render(request, 'accounts/create_profile.html', {'form': form})

Django模板不会呈现表单错误
