Error : 'User' object has no attribute 'get' when trying to access current user in ModelForms for a ModelChoiceField dropdown

Question

下面是 views.py，我正在尝试使用模型加载视图。在模型中，我需要根据当前登录的用户加载 modelchoicefield 并尝试以下解决方案（检查 forms.py。）当我运行它时，我得到

Attribute Error :object has no attribute 'get'

非常感谢帮助，Whosebug 中没有任何内容。

views.py:

class HomeView(View):
    def get(self, request, *args, **kwargs):

        form=PreDataForm(request.user)

        return render(request, 'mainlist.html',
                      { "form":form,

        })

models.py:

class PreData(models.Model):

    journalname = models.CharField(max_length=400, blank=False, null=True, default='')

forms.py:

class PreDataForm(forms.ModelForm):
    journalname = forms.ModelChoiceField(required=True)
    class Meta:
        model=PreData
        fields=['journalname']

    def __init__(self,user, *args, **kwargs):
        super(PreDataForm, self).__init__(user, *args, **kwargs)
        self.fields["journalname"].queryset = Journals.objects.filter(journalusername=user)

html 文件:

{% extends 'home-base.html' %}
{% load crispy_forms_tags %}
{% block title %}

Welcome to Metrics - JSM

{% block content %}

<div  class="col-md-9 col-centered"  >
    <div class="backeffect" >

            {% if data %}

            {% else %}

                <b>Seems you are first time around here, Why not <b>{% include 'modal_first_stage.html' %}</b>  to get started? :)</b>
            {% endif %}


{% endblock %}

ModelForm不带user。您应该将其从 super() 通话中删除。

def __init__(self, user, *args, **kwargs):
    super(PreDataForm, self).__init__(*args, **kwargs)
    self.fields["journalname"].queryset = Journals.objects.filter(journalusername=user)

稍微多一点的 re-usable 版本，将适用于通用 create/update 视图，是：

def __init__(self, *args, **kwargs):
    user = kwargs.pop('user')
    super(PreDataForm, self).__init__(*args, **kwargs)
    self.fields["journalname"].queryset = Journals.objects.filter(journalusername=user)
