How would I pass a user object or a request to my form for using it as an initial value for input textbox?
For example, I have my form:
class ContactForm(forms.Form):
contact_name = forms.CharField(required=True, initial="???")
contact_email = forms.EmailField(required=True)
subjects = forms.ChoiceField(choices=emailsubjects)
content = forms.CharField(
required=True,
widget=forms.Textarea
)
def __init__(self, *args, **kwargs):
self.request = kwargs.pop("request")
super(ContactForm, self).__init__(*args, **kwargs)
self.fields['contact_name'].label = "Your name:"
self.fields['contact_email'].label = "Your email:"
self.fields['content'].label = "What do you want to say?"
self.fields['subjects'].label = "Please, select the subject of your message"
Where i want my user.first_name to be as a default value for contact_name field.
Here is my views.py, where i call for form:
def ContactsView(request):
form_class = ContactForm(request=request)
# new logic!
if request.method == 'POST':
form = form_class(data=request.POST)
if form.is_valid():
contact_name = request.POST.get(
'contact_name'
, '')
contact_email = request.POST.get(
'contact_email'
, '')
form_content = request.POST.get('content', '')
subjects = form.cleaned_data['subjects']
subjects = dict(form.fields['subjects'].choices)[subjects]
# Email the profile with the
# contact information
template = get_template('threeD/email/contact_template.txt')
context = Context({
'contact_name': contact_name,
'subjects': subjects,
'contact_email': contact_email,
'form_content': form_content,
})
content = template.render(context)
email = EmailMessage(
"New message from " + contact_name,
content,
"Message - " + subjects + ' ',
['smart.3d.printing.facility@gmail.com'],
headers={'Reply-To': contact_email}
)
email.send()
messages.success(request, "Thank you for your message.")
return redirect('/index/contacts/')
return render(request, 'threeD/contacts.html', {
'form': form_class,
})
Any help would be very much appreciated
You have changed your form to take the request object. Therefore you can access self.request.user inside your form's methods:
class ContactForm(forms.Form):
...
def __init__(self, *args, **kwargs):
self.request = kwargs.pop("request")
super(ContactForm, self).__init__(*args, **kwargs)
self.fields['contact_name'].label = "Your name:"
self.fields['contact_name'].initial = self.request.user.first_name
You also have to update your view to pass the request object. Remember to update the code for GET and POST requests.
if request.method == 'POST':
form = ContactForm(data=request.POST, request=request)
...
else:
# GET request
form = ContactForm(request=request)
Finally, by passing the request to the form, you have tightly coupled it to the view. It might be better to pass the user to the form instead. This would make it easier to test the form separately from the view. If you change the form, remember to update the view as well.
You need to pass the initial values in the view:
views:
def ContactsView(request):
form_class = ContactForm(request=request,
initial={'contact_name': request.user.first_name})
...
