How to get current signed user in forms.py?

Question

I'm using ModelChoiceField to select Invoice provider in my forms. In the current case, I'm returning all the Providers to the queryset.

But I should return only Providers that created by the signed user. Provider has a ForeignKey field named user.

Here is my Form:

class InvoiceCreationForm(forms.Form):
    # ...
    provider = forms.ModelChoiceField(
        label='Provider',
        required=False,
        queryset=Provider.objects.all(),
        widget=forms.Select(attrs={
            'name': 'provider',
            'class': 'form-control',
            'id': 'input-invoice-provider',
        })
    )

I need to filter objects like this:

Provider.objects.filter(user=current_user)

How can I get the signed user? Or how can I get the request object outside of a view? I tried get the current user from __init__ method of the form then set it to self.user. But I can't use it in the query like self.user.

Getting the user in __init__() is only the first part of the solution. You also need to use that user to filter the queryset:

class InvoiceCreationForm(forms.Form):
    def __init__(self, *args, **kwargs):
         self.user = kwargs.pop('user', None)
         super(InvoiceCreationForm, self).__init__(*args, **kwargs)
         if self.user:
             self.fields['provider'].queryset = Provider.objects.filter(user=self.user)
