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>

            </div>

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)})
