python - Django Forms、request.user に初期値を設定

Question

以下を可能にする方法はありますか、それとも他の場所で行う必要がありますか?

class JobRecordForm(forms.ModelForm):
    supervisor = forms.ModelChoiceField(
        queryset    = User.objects.filter(groups__name='Supervisors'), 
        widget      = forms.RadioSelect,
        initial     = request.user # is there some way to make this possible?
    )    
    class Meta:
        model = JobRecord

代わりに view.py でこれを行う場合:

form = JobRecordForm( initial={'supervisor':request.user} )

その後、検証をトリガーしません。

http://docs.djangoproject.com/en/dev/ref/forms/api/#dynamic-initial-valuesを参照してください。

ミドルウェアとセーブ書き換えによるもうひとつの解決法 : ミドルウェアによる解決法どこでも「リクエスト」を呼び出すことができます。

""" ミドルウェア """

    # coding: utf-8 
from django.utils.thread_support import currentThread 
_requests = {}

def get_request():
    return _requests[currentThread()]

class GlobalRequestMiddleware(object):
    def process_request(self, request):  
        _requests[currentThread()] = request

""" 再書き込みを保存 """

class Production(models.Model):
    creator = models.ForeignKey(User, related_name = "%(class)s_creator")
    creation_date = models.DateTimeField(auto_now_add = True)
    modification_date = models.DateTimeField(auto_now = True)

    def save(self, force_insert = False, force_update = False):

        self.creator = get_request().user
        super(Production, self).save(force_insert = force_insert, force_update = force_update)
        return

You might want to handle this in your view function. Since your view function must create the initial form, and your view function knows the user.

form = JobRecordForm( {'supervisor':request.user} )

This will trigger validation of this input, BTW, so you can't provide hint values this way.

完全な答えについては、CBV ソリューションを次に示します。

class MyFormView(TemplateView, FormMixin):
    def get_initial(self):
        self.initial.update({'your_field': self.request.user})
        return super(MyFormView, self).get_initial()
