Accessing model data in Django template

Question

I am using the below lines to pass data to my template index.html, model1 being the class in my models.py.

     data = model1.objects.all()
     return TemplateResponse(request, 'index.html', {'data': data})

I am able to access data on the front end by using a for loop as shown below

 {% for x in data %}
   <h3>{{x.name}}</h3>
   <h4>{{x.department}}</h4>
 {% endfor %}

Since there are mutliple objects in this data, my question is if I want to access only the department of particular object with certain name, how can I do that?

For example here I am using a for loop, consider there are two objects in the data. Then the output would be

name1
department1
name2
department2

So now if I need to access only name2 without any loop, how can i do that?

Updating the question: I am updating this question with html, so that the question looks clear.

table id="example" class="table table-striped" cellspacing="1" width="100%">
    <thead>
  <tr>
    <th>ID</th>
    <th>Name</th>
    <th>Department</th>
    <th>View/Edit</th>
  </tr>
</thead>
<tbody>
  {% for x in data %}
  <tr>
    <td>{{x.id}}</td>
    <td>{{x.name}}</td>
    <td>{{x.department}}</td>
    <td>View</td>
  <button type="button" class="btn-sm btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  view</button></td>
  </tr>
  {% endfor %}

</tbody>

This is how my html looks, I am using data-table here. So all the data is captured in a table automatically. As you can see every row has a view button that I would implement. Once the user clicks the view button, I should pop up a modal dialog to show all the other details like {{x.dateJoined}} etc which I don't show in the table. But if I use a separate view to pop this dialog, I should send a request to the view from my template saying which row(with some ID) the user has clicked. How can i achieve that? How can I bind the view button with respective rows here?

You need to write custom template tag which will take the queryset and filtering parameters and returns you appropriate object, you can use simple_tag:

myapp/templatetags/myapp_tags.py

from django import template

register = template.Library()


@register.simple_tag
def get_model1_object(queryset, **filters):
    if not filters:
        raise template.TemplateSyntaxError('`get_model1_object` tag requires filters.')
    retrun queryset.filter(**filters).first()

Then in template:

{% load get_model1_object from myapp_tags %}

{% get_model1_object data name='blah' as obj %}

Note: Your filtering criteria might yield multiple results but in get_model1_object i am only returning the first object assuming your criteria will be strict, change it according to your needs.
