Why Are Tenant Domain URLs Not Displaying Correctly in My Django Login Portal?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

Hello, I’m new to Django multitenancy and have successfully implemented a multi-tenant setup using django-tenants with a shared database and separated schemas.

I’m aiming to create a login portal similar to the one shown here: https://letmein.blackboard.com/router. The portal should allow users to log in by selecting an active tenant from a dropdown menu. However, the tenant domain URLs are not displaying correctly on my login page. Instead of showing the proper URL (e.g., tenant.localhost.com), clicking on a tenant results in a None response.

I suspected the issue might lie with my authentication system, so I created a test page where the list of tenants displays correctly. Yet, clicking on the listed tenant still returns None for the domain URL.

Below is a sample snippet from my login page (login.html template):

HTML
<input
            type="password"
            name="password"
            id="password_id"
            required
            placeholder="Password"
          />
          <select class="form-control" name="center" id="centerSelect" onchange="redirectToCenter()">
            <option value="http://{{ tenant.domain_url}}">--Select Your Center--</option>
            {% for tenant in tenants %}
                <option value="http://{{ tenant.domain_url}}">{{ tenant.center_name }}</option>
                {% empty %}
                <option value="http://{{ tenant.domain_url}}">No centers available</option>
            {% endfor %}
        </select>r paste code here

The front-end displays the following image:

I would appreciate any help in resolving the issue with the tenant domain URLs not displaying and redirecting correctly on my login page. Thanks!

Django Multitenancy Domain URL Issue

Looking at your login page template and the issue you're experiencing, I can see that you're having trouble with the tenant domain URLs not displaying correctly in your dropdown menu. When a tenant is selected, you're getting a None response instead of the proper domain URL.

The Issue

The problem appears to be in how you're accessing the domain URL in your template. In the django-tenants framework, tenant domains are typically stored in a separate model related to the tenant model.

Solution

Here are some steps to fix your issue:

First, make sure your view is correctly passing the tenant data to the template:

PYTHON
def login_view(request):
    # Get all tenants with their domains
    tenants = Client.objects.select_related('domain').all()
    # Or if you have a custom model structure:
    # tenants = Client.objects.all().prefetch_related('domains')
    
    return render(request, 'login.html', {'tenants': tenants})

Update your template to correctly access the domain URL:

HTML
<select class="form-control" name="center" id="centerSelect" onchange="redirectToCenter()">
    <option value="">--Select Your Center--</option>
    {% for tenant in tenants %}
        {% with domain=tenant.domains.first %}
            <option value="http://{{ domain.domain }}">{{ tenant.center_name }}</option>
        {% endwith %}
    {% empty %}
        <option value="">No centers available</option>
    {% endfor %}
</select>

Make sure your JavaScript function redirectToCenter() is properly defined:

JAVASCRIPT
function redirectToCenter() {
    var select = document.getElementById('centerSelect');
    var url = select.options[select.selectedIndex].value;
    if (url) {
        window.location.href = url;
    }
}

Alternative Approach

If your tenant model structure is different, you might need to adjust how you access the domain. For example, if you're using the default django-tenants structure:

HTML
{% for tenant in tenants %}
    {% with domain=tenant.domains.all.0 %}
        <option value="http://{{ domain.domain }}">{{ tenant.center_name }}</option>
    {% endwith %}
{% endfor %}

Make sure to check your tenant model structure and adjust the template accordingly to correctly access the domain URL.
