我如何提交默认登录用户的表单？

Question

注册后，系统会提示您进入登录页面，登录后，您将被重定向到另一个页面，该页面包含用于收集有关新用户的其他信息的表单。 问题是如果我没有在 html 文件中指定 {{form.user}} 实例，则表单不会提交。 可能是因为默认情况下无法识别 user_id。 当我指定它时，该表单让我从现有用户中进行选择，我希望它默认为登录用户 go。

楷模

class AdditionalInfoModel(models.Model):
    objects = None
    skill_choices = (('Beginner', 'BEGINNER'),
                 ('Intermediate', 'INTERMEDIATE'),
                 ('Expert', 'EXPERT'))

    user = models.OneToOneField(User, on_delete=models.CASCADE)
    location = models.CharField(max_length=30, blank=True)
    assumed_technical_ski_level = models.CharField(max_length=30, choices=skill_choices)
    years_of_experience = models.PositiveIntegerField(blank=True)
    money_to_spend = models.PositiveIntegerField(blank=True)
    def __str__(self):
        return self.user.username

观点

class CreateInfoView(LoginRequiredMixin, CreateView):
    model = AdditionalInfoModel

    form_class = AdditionallnfoModelForm
    template_name = "user_ski_experience/additional_info.html"
    
    def get_form_kwargs(self):
        variable_to_send = super(CreateInfoView, 
        self).get_form_kwargs()
        variable_to_send.update({'pk': None})
        return variable_to_send

    def get_success_url(self):
        return reverse('aplicatie2:home')

forms

class AdditionallnfoModelForm(forms.ModelForm):
    class Meta:
        model = AdditionalInfoModel
        fields = '__all__'

    def __init__(self, pk,  *args, **kwargs):
        super(AdditionallnfoModelForm, self).__init__(*args, 
        **kwargs)
        self.pk = pk

    def clean(self):
        return self.cleaned_data

html

{% load crispy_forms_tags %}
{% block content %}

    <meta charset="UTF-8">
    <title>Title</title>
</head>

<body>

    <form method="post">

        <h2> This will help us get to know your ski experience 
        </h2>

登录和注册是使用标准 django 模型完成的

我建议使用禁用字段并通过表单的初始化方法设置用户的初始值。 禁用字段在 POST 请求中被完全忽略，因此用户将无法更改您通过该字段设置的默认用户。

Django 关于禁用属性的文档： https://docs.djangoproject.com/en/4.0/ref/forms/fields/#disabled

视图.py

class CreateInfoView(LoginRequiredMixin, CreateView):
    model = AdditionalInfoModel

    form_class = AdditionallnfoModelForm
    template_name = "user_ski_experience/additional_info.html"
    
    def get_form_kwargs(self):
        variable_to_send = super(CreateInfoView, 
        self).get_form_kwargs()
        variable_to_send.update({'pk': None})
        variable_to_send.update({'pk_user': self.request.user.pk})
        return variable_to_send

    def get_success_url(self):
        return reverse('aplicatie2:home')

forms.py

class AdditionallnfoModelForm(forms.ModelForm):
    class Meta:
        model = AdditionalInfoModel
        fields = '__all__'

    def __init__(self, pk, *args, **kwargs):
        pk_user = kwargs.pop('pk_user')
        super(AdditionallnfoModelForm, self).__init__(*args, 
        **kwargs)
        self.pk = pk

        # Make the user field readonly
        self.fields['user'].disabled = True
        self.fields['user'].initial = pk_user

    def clean(self):
        return self.cleaned_data

编辑：还在您的 HTML 中发现了问题。表单不会提交，因为您的 HTML 不适合提交表单。 像下面这样的东西应该有效：

{% load crispy_forms_tags %}
{% block content %}
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>

<body>

    <!-- Place the POST endpoint URL in the action attribute of the 'form' tag -->
    <form method="post" action="{% url 'aplicatie2:home' %}">
        {% csrf_token %}
        <h1> Let's get started with some questions ! </h1>
        <h2> This will help us get to know your ski experience 
        </h2>
        <li> Your user name is: {{form.user|as_crispy_field}}</li>
        <li> Where do you live ?    
            {{form.location|as_crispy_field}}  </li>
        <li> How would you rank yourself as a skier ?    
            {{form.assumed_technical_ski_level|as_crispy_field}}  
       </li>
        <li> How many years of ski experience do you have ?    
            {{form.years_of_experience|as_crispy_field}}  </li>
        <li>  How much ar you willing to spend ?    
            {{form.money_to_spend|as_crispy_field}}  </li>

        <!-- You can't use <button> element for submitting a form without special JS -->
        <input type="submit">Submit</button>
    </form>

</body>
