Django from 没有进入 html 模板

Question

正如问题标题"{{form}}" from is not being loaded into html template 我在以前的项目中检查过的一样，我有几乎相同的代码，不同之处在于必填字段、命名等。机制是相同的。 在这些项目中，注册功能在这里完美运行，它甚至没有抛出错误，只是不显示任何内容。 难怪这里可能有什么问题。

forms.py

    from django import forms
    from django.contrib.auth.forms import UserCreationForm    
    from .models import Profile 
    
    class RegistrationForm(UserCreationForm):
        email = forms.EmailField(max_length=60, help_text="Required field")    
    
        class Meta:
            model = Profile
            fields = ["email", "username", "password", "password2", "calories_plan", "diet_type"]

views.py

    def registration_view(request):
        context = {}
        if request.POST:
            form = RegistrationForm(request.POST)
            if form.is_valid():
                email = form.cleaned_data.get("email")
                password = form.cleaned_data.get("password")
                new_account = authenticate(email=email, password=password)
                login(request, new_account)
            else:
                context["registration_form"] = form
        else:
            form = RegistrationForm()
            context["registration_form"] = form
        return render(request, "Account/registration.html", context)

html模板

    {% extends 'main.html' %}
    {% load crispy_forms_tags %}
    
    {% block content %}
    
        <div class="content-section">
            <form method="post">
                {% csrf_token %}
                <fieldset class="form-group">
                    <legend class=border-bottom mb-4>Join today                     
                        {{ form }}
                    </legend>
                </fieldset>
                <div class="form-group">
                    <button class="btn btn-outline-info" type="submit">Sign Up</button>
                </div>          
            </form>
    
            <div class="border-top pt-3">
                <small class="text-muted">
                    Already have an account?
                    <a href="#" class="ml-2">
                        Log In
                    </a>
                </small>
            </div>
        </div>
    
    {% endblock %}

以及它在浏览器中的外观。

您将'registration_form' 传递给上下文，但在模板中您调用的是{{ form }}。

替换： {{ form }} 和： {{ registration_form }}
