Tip

For best results, initiate chat on the files or code changes.

@igennova Based on the repository information I've gathered, I'll implement a solution for sending email notifications when someone starts an encrypted chat. Here's my implementation:

First, let's modify the start_thread function in website/views/user.py to send an email notification:

@login_required
def start_thread(request, user_id):
    if request.method == "POST":
        other_user = get_object_or_404(User, id=user_id)

        # Check if a thread already exists between the two users
        thread = Thread.objects.filter(participants=request.user).filter(participants=other_user).first()

        # Create a new thread if one doesn't exist
        is_new_thread = False
        if not thread:
            # Create a new thread
            thread = Thread.objects.create()
            thread.participants.set([request.user, other_user])  # Use set() for ManyToManyField
            is_new_thread = True

        # If this is a new thread, send an email notification to the recipient
        if is_new_thread and other_user.email:
            # Generate the link to the encrypted chat
            current_site = get_current_site(request)
            chat_url = f"https://{current_site.domain}/messaging/?thread={thread.id}"
            
            # Prepare email content
            subject = f"New encrypted chat from {request.user.username}"
            
            # Render email templates
            context = {
                'sender': request.user.username,
                'recipient': other_user.username,
                'chat_url': chat_url,
                'site_name': current_site.name,
            }
            
            msg_plain = render_to_string('email/new_encrypted_chat.html', context)
            msg_html = render_to_string('email/new_encrypted_chat.html', context)
            
            # Send the email notification
            send_mail(
                subject,
                msg_plain,
                settings.EMAIL_TO_STRING,
                [other_user.email],
                html_message=msg_html
            )

        return JsonResponse({"success": True, "thread_id": thread.id})

    return JsonResponse({"success": False, "error": "Invalid request"}, status=400)

Now, let's create an email template at website/templates/email/new_encrypted_chat.html:

{% extends "email/base_email.html" %}

{% block content %}
<p>Hello {{ recipient }},</p>

<p>{{ sender }} has started a new encrypted chat with you.</p>

<p>To view and respond to this chat, please click the button below:</p>

<a href="{{ chat_url }}" style="background-color:#4CAF50;border:none;color:white;padding:15px 32px;text-align:center;text-decoration:none;display:inline-block;font-size:16px;margin:4px 2px;cursor:pointer;border-radius:5px;">
    Open Encrypted Chat
</a>

<p>Or copy and paste this link into your browser:</p>
<p>{{ chat_url }}</p>

<p>This is a secure, end-to-end encrypted conversation. Your messages are protected and can only be read by you and {{ sender }}.</p>

<p>If you did not expect this chat request, you can safely ignore this email.</p>

<p>Best regards,<br>
{{ site_name }} Team</p>
{% endblock %}

This implementation:

Checks if a new thread is being created (to avoid sending emails for existing conversations)
Generates a direct link to the conversation
Creates an HTML email with a clear call-to-action button
Provides context about the encrypted nature of the conversation

The recipient will receive an email notification with a link that takes them directly to the encrypted chat thread.

Uh oh!

When someone starts an encrypted chat send the recipient an email with a link to open it #3860
