Passing an initial value into a form field from previous detail view












0















I a bit confused how to do this, I have a "contact user" button on a user detail page. I am trying to set the initial form value for the email field as the users email from the previous detail page view, so that it pre-populates.



Would I pass the user.email as a kwarg into the button url?



views.py



def Contact(request):
form_class = ContactForm

# 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', '')

# Email the profile with the
# contact information
template = get_template('contact_template.txt')
context = {
'contact_name': contact_name,
'contact_email': contact_email,
'form_content': form_content,
}
content = template.render(context)

email = EmailMessage(
"New contact form submission",
content,
"Your website" +'',
['youremail@gmail.com'],
headers = {'Reply-To': contact_email }
)
email.send()
return redirect('contact_form')


return render(request, 'portal/contact_form.html', {
'form': form_class,
})


forms.py



from django import forms
class ContactForm(forms.Form):
contact_name = forms.CharField(required=True)
contact_email = forms.EmailField(required=True, initial='{ kwarg }')
content = forms.CharField(
required=True,
widget=forms.Textarea
)


user_detail.html



<div class="col-lg-4 text-center p-5" style="padding-right:20px; border-right: 1px solid #e5e5e5;">
<a href="{% url 'portal:contact_form' kwarg.user.email %}">
<h1><i class="fa fa-2x fa-envelope-o text-success" aria-hidden="true"></i></h1>
<p class="text-muted mt-3 ">Contact Customer</p>
</a>

There are multiple ways to do that. Like for example:



Method 1: Send it in URL Querystring



from you previous details view, send the email in url querystring. For example:



 def DetailForm(request, *args, **kwargs):
...
if form.is_valid():
# do some things
user_email = form.cleaned_data.get('user_email') # assuming its the form field you are using for catching user email

redirect_url = "{}?user_email={}".format(self.get_success_url(), user_email)
return HttpResponseRedirect(redirect_url)


And catch it in Next form view:



  def Contact(request):
form_class = ContactForm(initial={'contact_email': request.GET.get('user_email')})
...


Method 2: Store in session.



Its almost similar to last approach, but it stores the data in session.



def DetailForm(request, *args, **kwargs):
...
if form.is_valid():
# do some things
request.session['user_email'] = form.cleaned_data.get('user_email') # Storing data in session

# every other code


And get it in Next form view:



  def Contact(request):
form_class = ContactForm(initial={'contact_email': request.session.get('user_email')})
...


Update



If you are coming from a detail page, means you have the access to the object. So in the detail page, update the contact button like this:



<a href="{% url 'portal:contact_form' object.email %}">contact</a>  // or user.email if you are passing user object as user in context


in Contact View:



def Contact(request, email):
if request.method == "GET":
form = ContactForm(initial={'contact_email': email)})
