Условно отображать с помощью Crispy Forms - объект ошибки 'tuple' не имеет атрибута 'get'

/ 26 июня 2019

Я пытаюсь найти решение для этого вопроса: Условно отобразить набор полей с хрустящими формами .

Однако я не могу завершить его из-за ошибки: Метод запроса: GET URL запроса: http://127.0.0.1:8000/project/customer/ Джанго версия: 2.2.2 Тип исключения: AttributeError Значение исключения:

Объект 'tuple' не имеет атрибута 'get'

model.py: 

class Project(models.Model):
    project_name = models.CharField(max_length=50, primary_key=True)
    # who owns the project?
    owner = models.ForeignKey(User, on_delete=models.PROTECT)
    created_date = models.DateTimeField(auto_now=False, auto_now_add=True)
    is_active = models.BooleanField(default=True)
    ## when on call starts 5 pm?
    on_call_begings = models.TimeField(auto_now=False, auto_now_add=False, default=datetime.time(17, 00))
    ## when on call ends 9 am?
    on_call_ends = models.TimeField(auto_now=False, auto_now_add=False, default=datetime.time(9, 00))
    country = CountryField()
    follow_holidays = models.BooleanField(default=True)
    slug = models.SlugField()


    class Meta:
        verbose_name = "Project"
        verbose_name_plural = "Projects"

    def __str__(self):
        return self.project_name

    def get_absolute_url(self):
        return reverse("Project_detail", kwargs={"slug": self.slug})

Forms.py 

from django import forms
from core.models import Project
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Fieldset, Field, Layout

class ProjectForm(forms.ModelForm):
    class Meta:
        model = Project
        fields = ("project_name", "is_active", "on_call_ends", "on_call_begings", 'country', 'follow_holidays')

    def __init__(self, *args, **kwargs):
        super(ProjectForm, self).__init__(args, kwargs)
        self.username = kwargs.pop('user', None)
        self.helper = FormHelper(self)
        self.helper.attrs = {'novalidate': ''}
        self.helper.layout = Layout(
            Fieldset("project_name", "is_active", "on_call_ends", "on_call_begings", 'country', 'follow_holidays')
        )
        if self.username and self.username.is_staff:
            self.helper.layout.append(Fieldset(
                'owner',
        )
    )

Проблема есть. Когда я удаляю метод init, он работает нормально.

view.py 

def addProject(request):
    '''
    The view manages Customer's project and its settings
    '''
    print('test')
    if request.method == 'POST':
        project_form = ProjectForm(request.POST, 
                        instance=Project(), 
                        prefix="project"
                        )
        if project_form.is_valid():
            project = project_form.save(commit=False)
            # project.owner = request.user
            project.save()
            return redirect("home")

    else:
        project_form = ProjectForm(request.POST, user=getattr(request, 'user', None))
        # settings_form = ProjectSettingsForm(instance=ProjectSettings(), prefix="settings")

    return render(request, 'project.html', {
        'form': project_form
    })
