    invoice_year = forms.CharField(max_length=255, required=False,
                                      widget=forms.TextInput(attrs={'placeholder': 'Search Year'}))

from django import forms
from statistics.choices import MONTH_CHOICES


class StatisticsForm(forms.Form): 
    invoice_year = forms.CharField(max_length=255, required=False,
                                  widget=forms.TextInput(attrs={'placeholder': 'Search Year'}))
    month_choice = forms.ChoiceField(choices=MONTH_CHOICES)

    def clean_invoice_year(self):
        invoice_year_val = self.cleaned_data.get('invoice_year')
        if condition_not_satisfied:
            raise forms.ValidationError('Invalid invoice year')
        return invoice_year_val
