How can I generate a comma-separated list of insurance names for each therapist?

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

I'm trying to dynamically populate paragraph tags with data from my database. Specifically, I want each paragraph to appear as follows: <p>Insurances: BCBS, Aetna, Molina</p>, where BCBS, Aetna, Molina are the names of insurances associated with a given therapist.

In my models, I have a many-to-many relationship between Therapist and Insurance defined as follows:

PYTHON
class Therapist(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    license_type = models.CharField(max_length=50)
    active = models.BooleanField(default=True)
    certifications = models.ManyToManyField(Certification)
    insurances = models.ManyToManyField(Insurance)
    populations = models.ManyToManyField(Population)
    bio = models.TextField()
    picture = models.ImageField(upload_to="static/bio_pics", default=None)

    def __str__(self) -> str:
        return f"{self.first_name} {self.last_name}, {self.license_type}"

class Insurance(models.Model):
    name = models.CharField(max_length=50)

    def __str__(self) -> str:
        return self.name

My template (with the relevant part shown) looks like this:

DJANGO
{% for therapist in therapists %}
    <div class="therapist">
        <img class="bio-pic"
             alt="{{ therapist.first_name }} {{ therapist.last_name }} smiling at the camera."
             src="{{ therapist.picture }}" />
        <h3 class="therapist-name">{{ therapist.first_name }} {{ therapist.last_name }}, {{ therapist.license_type }}</h3>
        <p class="insurances">
            Insurance:
            {% for insurance in therapist.insurances.all %}<strong>{{ insurance.name }}</strong> |{% endfor %}
        </p>
        <a class="therapist-link" href="/{{ therapist.id }}">Learn more about {{ therapist.first_name }}</a>
    </div>
{% endfor %}

My goal is to simplify this by obtaining a list of insurance name strings so I can use something like {{ therapist.insurances.all|join: ", " }} in my template. However, that approach fails.

Is there a method to directly retrieve a list of insurance names for each therapist, or should I consider a different approach to accessing and displaying that information?

Displaying Insurance Names in Django Templates

You have a few options to simplify how you display the list of insurance names for each therapist.

Option 1: Use a Custom Template Filter

The issue with {{ therapist.insurances.all|join:", " }} is that it's trying to join the Insurance objects, not their names. You can create a custom template filter:

PYTHON
# In your app's templatetags/custom_filters.py
from django import template

register = template.Library()

@register.filter
def insurance_names(insurances):
    return ", ".join([insurance.name for insurance in insurances.all()])

Then in your template:

DJANGO
{% load custom_filters %}
<p class="insurances">
    Insurance: {{ therapist.insurances|insurance_names }}
</p>

Option 2: Add a Method to Your Therapist Model

Add a method to your Therapist model that returns the formatted insurance names:

PYTHON
class Therapist(models.Model):
    # existing fields...
    
    def get_insurance_names(self):
        return ", ".join([insurance.name for insurance in self.insurances.all()])

Then in your template:

DJANGO
<p class="insurances">
    Insurance: {{ therapist.get_insurance_names }}
</p>

Option 3: Modify Your Current Template Approach

Your current approach can be simplified by removing the pipe character at the end and using CSS for formatting:

DJANGO
<p class="insurances">
    Insurance:
    {% for insurance in therapist.insurances.all %}
        <strong>{{ insurance.name }}</strong>{% if not forloop.last %}, {% endif %}
    {% endfor %}
</p>

This adds a comma between insurance names but not after the last one.

Option 4: Annotate in the View

You can also prepare the data in your view before sending it to the template:

PYTHON
from django.db.models import F, Value
from django.db.models.functions import Concat

def your_view(request):
    therapists = Therapist.objects.prefetch_related('insurances')
    
    # Add insurance_list to each therapist
    for therapist in therapists:
        therapist.insurance_list = ", ".join([i.name for i in therapist.insurances.all()])
    
    return render(request, 'your_template.html', {'therapists': therapists})

Then in your template:

DJANGO
<p class="insurances">
    Insurance: {{ therapist.insurance_list }}
</p>

Option 2 or 4 would be the most efficient approaches, especially if you're displaying multiple therapists on a page.
