I am facing a strange problem while implementing ChoiceField and UpdateView in django. I have made a small clip showing the problem that I am facing. Please watch it with subtitles/cc enabled. It will give an idea about the problem I am facing. https://youtu.be/M36TnlJvrZs. The problem goes like this.....
During CreateView, I set the 'gender' ChoiceField as 'Female'. But in UpdateView it pre-populates the 'gender' ChoiceField as Male.
However, The ListView renders the 'gender' field properly as 'Female'.
And strangely, the django admin panel, displays no value at all for the 'gender' field.
Here are all the codes:
models.py:
from django.db import models
from django.core.urlresolvers import reverse
gender_choices = (('Male', 'Male'), ('Female', 'Female'))
class Birth(models.Model):
full_name = models.CharField(max_length = 100)
gender = models.CharField(max_length=6, choices=gender_choices)
date_of_birth = models.DateField()
place_of_birth = models.CharField(max_length = 50)
mother_name = models.CharField(max_length = 50)
father_name = models.CharField(max_length = 50)
address_at_time_of_birth = models.TextField(max_length = 500)
permanent_address = models.TextField(max_length = 500)
registration_no = models.CharField(max_length = 50)
remarks = models.CharField(max_length = 200)
registration_date = models.DateField()
issue_date = models.DateField()
def get_absolute_url(self):
return reverse('birth:birth_update', kwargs={'pk':self.pk})
#return reverse('birth:birth_home')
def __str__(self):
return self.full_name
forms.py:
from django import forms
from .models import *
class BirthForm(forms.ModelForm):
full_name = forms.CharField()
gender = forms.ChoiceField(choices = gender_choices, widget=forms.Select())
date_of_birth = forms.DateField(widget = forms.DateInput(attrs = {'placeholder':'DD/MM/YYYY'}))
place_of_birth = forms.CharField()
mother_name = forms.CharField()
father_name = forms.CharField()
address_at_time_of_birth = forms.CharField(widget = forms.Textarea())
permanent_address = forms.CharField(widget = forms.Textarea())
registration_no = forms.CharField(required = False)
registration_date = forms.DateField(required = False, widget = forms.DateInput(attrs = {'placeholder':'DD/MM/YYYY'}))
remarks = forms.CharField(required = False)
issue_date = forms.DateField(required = False, widget = forms.DateInput(attrs = {'placeholder':'DD/MM/YYYY'}))
class Meta:
model = Birth
fields = '__all__'
views.py:
from django.views.generic import ListView, CreateView, UpdateView

class NewBirth(CreateView):

form_class = BirthForm
#fields = '__all__'
template_name = 'birth/birth_add.html'
def form_valid(self, form):
obj = form.save(commit = False)
if not obj.registration_date:
obj.registration_date = date.today()
if not obj.issue_date:
obj.issue_date = date.today()
if not (date(1900, 1, 1) <= obj.date_of_birth <= date.today()):
form.add_error('date_of_birth', 'Please enter a valid date')
return super(NewBirth, self).form_invalid(form)
obj.full_name = obj.full_name.upper()
obj.gender = obj.gender.upper()
obj.place_of_birth = obj.place_of_birth.upper()
obj.mother_name = obj.mother_name.upper()
obj.father_name = obj.father_name.upper()
obj.address_at_time_of_birth = obj.address_at_time_of_birth.upper()
obj.permanent_address = obj.permanent_address.upper()
if obj.remarks:
obj.remarks = obj.remarks.upper()
self.object = form.save()
return super(NewBirth, self).form_valid(form)
class BirthUpdate(UpdateView):

obj.issue_date = date.today()
if not (date(1900, 1, 1) <= obj.date_of_birth <= date.today()):
form.add_error('date_of_birth', 'Please enter a valid date')
return super(BirthUpdate, self).form_invalid(form)
obj.full_name = obj.full_name.upper()
obj.gender = obj.gender.upper()
obj.place_of_birth = obj.place_of_birth.upper()
obj.mother_name = obj.mother_name.upper()
obj.father_name = obj.father_name.upper()
obj.address_at_time_of_birth = obj.address_at_time_of_birth.upper()
obj.permanent_address = obj.permanent_address.upper()
if obj.remarks:
obj.remarks = obj.remarks.upper()
self.object = form.save()
return super(BirthUpdate, self).form_valid(form)
I searched a lot and experimented a lot as well, but to no avail. Seriously need help. Also if this approach is not correct, what should be the correct working approach??
