[DOCKER] Django Tutorial (Blog App Creation) ⑦ --Front End Complete

Last time, in Django Tutorial (Blog App Creation) ⑥ --Article Details / Edit / Delete Function, we created the details, edit, and delete screens for each article. ..

This time, we will make major adjustments to the template, but if we divide it roughly, we will do the following.

  1. Creating a screen common to all pages

  2. Creating a navigation bar

  3. Modify each template

  4. Delete unnecessary templates and processes

Creating a screen common to all pages

Not limited to Django, there are places on the homepage that are displayed in common even if the screen changes. In Qiita, the green navigation bar displayed at the top is a good example.

That's why we use ** common templates ** as a useful feature of Django. Simply put, the common parts are put together in one file, The different part for each screen is that you call and use a different template.

To do this, first create a file directly under the template folder. This time, let's create a file called /template/base.html.

└── templates
    ├── base.html #add to
    └── blog
        ├── index.html
        ├── post_confirm_delete.html
        ├── post_detail.html
        ├── post_form.html
        └── post_list.html

Write common processing in this file, and the parts that differ for each screen I will call a file such as post_detail.html.

Modify base.html

The contents will be like this.

base.html
