You will get a great idea of what I am trying to accomplish by the picture. click here to see my demo client page Below is my best attempt on how I can see this working, but I obviously don't know how to actually do it. #client_detail.html {% extends "base_generic.html" %} {% block content %} <h1>Client: {{ compuweatherclient.client }}</h1> <p><strong>City:</strong> {{ compuweatherclient.city }}</p> <p><strong>State:</strong> {{ compuweatherclient.state }}</p> <p><strong>Zipcode:</strong> {{ compuweatherclient.zipcode }}</p> <a href="{% url 'catalog:renderpdf' %}">PDF</a> <!--<a href="{% url 'catalog:renderpdf' var1=compuweatherclient.client %}" ><button class="btn btn-primary">pdf</button></a>--> {% … -
