Django 5.1.1
Python 3.12.4
HTMX 1.9.12
Goal:
The table loads and the 1st record or selected record appears in the index_2.html form and
can be edited/saved and also the user can add a new record if desired.
Problem: Also see Traceback file at the end.
App loads a table with pagination while tracking page# and 1st record displayed ‘id’ then includes
{% include ‘turnover_app/index_2.html’ %}
when index_2.html page tries to load get the hated NoReverseMatch Error (see below)
NOTE: If both HTMX buttons have a hard number in the hx-get=“{% url ‘turnover_app:edit_turn’ 12 %}”
the page loads fine without issue other than I obviously cannot use the htmx buttons
If either hx-get=“{% url ‘turnover_app:edit_turn’ tologs.pk %}” has a pk var or any var in it
then NoReverseMatch Error alerts.
