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

Question

So below is the views.py and I'm trying to load a view with modelform. And within the modelform I need to load modelchoicefield depending on the current user logged in and tried the below solution(check forms.py.) When I run it, i get

Attribute Error :object has no attribute 'get'

Help is highly appreciated, there's nothing in stackoverflow.

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 file:

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

            {% else %}

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

Answer 1

ModelForm does not take user. You should remove it from your super() call.

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

A slightly more re-usable version, which will work with the generic create/update views, is:

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