django - Django - 帐户设置 BooleanField

问题描述

我在这里查看了与 Django 和 BooleanField 更新相关的大部分帖子，但我找不到任何与我的问题解决方案相关的帖子。我有一个自定义用户models.py：

# Own custom user model
class Account(AbstractBaseUser):

    username = models.CharField(max_length=30, unique=True)

    guardianSource = models.BooleanField(default=True)
    bbcSource = models.BooleanField(default=False)
    independentSource = models.BooleanField(default=False)

    categoryCoronaVirus = models.BooleanField(default=False)
    categoryPolitics = models.BooleanField(default=False)
    categorySport = models.BooleanField(default=False)

当我注册用户时，它似乎在数据库中注册了复选框的所有正确值。问题是当我想编辑用户信息时，我看不到是否在注册时选中了复选框，它会显示复选框本身，但它们都是空的（False）。但是，它正确地请求用户名并显示它，以便我可以编辑它，但所有复选框都未选中。视图.py：

def account_view(request):
    if not request.user.is_authenticated:
        return redirect('login')
    context = {}
    if request.POST:
        form = AccountUpdateForm(request.POST, instance=request.user)
        if form.is_valid():
            form.save()
            context['success_message'] = "Updated"
    else: # Display the saved user details from database
        form = AccountUpdateForm(
                                initial = {
                                'username':request.user.username,
                                "guardianSource": request.user.guardianSource,
                                "bbcSource": request.user.bbcSource,
                                "independentSource": request.user.independentSource,

                                "categoryCoronaVirus": request.user.categoryCoronaVirus,
                                "categoryPolitics": request.user.categoryPolitics,
                                "categorySport": request.user.categorySport,
                                            })
    context['account_form'] = form
    return render(request, 'accounts/account.html', context)

帐户html：

{% extends 'base.html' %}

{% block content %}

  <h1 class="h3 mb-3 font-weight-normal">Account Settings</h1>

            {% endfor %}

    {% if account_form.non_field_errors %}
        <div style="color:red;">
                <p>{{account_form.non_field_errors}}</p>

    {% endif %}

{% endblock content %}

在此先感谢，如果我的帖子被重复，我很抱歉。

编辑：发现问题。在 account.html 文件中，每个输入类型复选框的值都是错误的。我改变了什么：

<input type="checkbox" name="guardianSource" id="guardianSource" value="{{account_form.initial.guardianSource}}" >

至：

<input type="checkbox" name="guardianSource" id="guardianSource" value="{{account_form.guardianSource}}" >

对于用户名输入后的所有输入值，initial必须删除
