Template issue

• Regarding URL and template tags

  • create templates for individual apps

  • folder structure

    <app-dir>
        |-> templates
            |-> <dir-with-same-name-of-app>
                |-> file1.html
                |-> file2.html
    

  • this may cause some issues if html paths aren't defines properly

  • assuming file1.html is base.html and file2.html is home.html, and home extends base, the extend tag should look like this

    {%extends '<appname>/base.html>'%}
    

    NOT

    {%extends 'base.html>'%}
    

  • if urls.py is setup properly, django will definitely find the templates directory but wont be able to load home.html or base.html as they are inside templates/<appname> directory.

• Regarding Views

  • assuming using ClassViews, the template_name should look like this

    template_name = '<appname>/home.html'
    

Sending Context Data while using TemplateView

• reference Ref 1 Ref 2

• lets assume a template view

  from django.views.generic.base import TemplateView
  from .service import get_json_data
  
  class HomePageView(TemplateView):
      template_name = 'someapp/home.html'
  
      def get_context_data(self, *args, **kwargs):
          context =  super().get_context_data(*args, **kwargs)
          context['data'] = get_json_data()
          return context
  

• get_json_data is a very simple function that uses requests module to consume an API and return the json output

• this view receives the json data from get_json_data() and stores as an item of the context, when called, it sends the context with it, and allows html pages to show the data
• in home.html using this code bellow will excerpt the json data received from api

  <p>{{ data }}</p>
