django - CreateView 模型对象到模板

问题描述

所以我试图将对象列表传递到我的模板中。我希望我的 profile.html 反映模型中的信息。我在 ListView 上找到了一些文档，但在 CreateView 上没有找到。唯一传递给模板的是 {{ user.username }}。任何建议将不胜感激。

profile.html

{% extends 'base.html' %}
{% block title %}User Profile{% endblock %}
{% block content %}
{% if user.is_authenticated %}
<p>User: {{ user.username }} logged in.</p>
<p><a href="{% url 'homepage' %}">homepage</a></p>
<p><a href="{% url 'logout' %}">logout</a></p>
{% else %}
<a href="{% url 'login' %}">login</a> |
<a href="{% url 'signup' %}">signup</a>
{% endif %}
{% endblock %}

模型.py

class Volunteer(CustomUser):
    user = models.OneToOneField(CustomUser, on_delete=models.CASCADE, primary_key=True)
    about_me = models.TextField(default='')    

    class Meta:
         db_table = "volunteer"

表格.py

class VolunteerSignUpForm(UserCreationForm):

class Meta(UserCreationForm.Meta):
    model = Volunteer
    fields = ("username", "email", "first_name", "last_name",)
@transaction.atomic
def save(self):
    user = super(VolunteerSignUpForm, self).save(commit=False)
    user.is_volunteer = True
    user.save()
    return user

视图.py

class VolunteerSignUp(CreateView):
form_class = VolunteerSignUpForm
success_url = reverse_lazy('login')
template_name = 'volunteer_signup.html'
#added code from answer
def get_context_data(self, **kwargs):
    context = super(VolunteerSignUp, self).get_context_data(**kwargs)
    context['profile_list'] = Volunteer.objects.all()
    return context

profile.html 以下是一些 iv 试图获取信息但不起作用的东西。

<ul>
    {% for volunteer in object_list %}
    <li>{{ volunteer.about_me }}</li>
    {% endfor %}
</ul>

<ul>
    {% for volunteer in profile_list %}
    <li>{{ volunteer.about_me }}</li>
    {% endfor %}
</ul>

{% if profile_list %}

{% else %}
  <p>There is no info.</p>
{% endif %}

解决方案

您可以在课堂上使用 get_context_data() 方法。

class VolunteerSignUp(CreateView):
    form_class = VolunteerSignUpForm
    success_url = reverse_lazy('login')
    template_name = 'volunteer_signup.html'

    def get_context_data(self, **kwargs):
        data = super(VolunteerSignUp, self).get_context_data(**kwargs)
        data['profile_list'] = 'your queryset goes here'
        return data
