Learn
Congratulations, this concludes the lesson on Flask templates. In this lesson we:
- Created a file structure that works with the Jinja2 template engine
- Rendered pages in our browser using files called templates
- Shared our application data for use within templates
- Applied filters to our data within our templates
- Utilized if statements to bring decision making to our templates
- Implemented for loops to perform repetitive tasks in our templates
- Moved common content to separate files to be shared by many templates
To show the power of what we have learned let’s add a simple navigation bar to the app.
Instructions
1.
Things added to our app are:
- an “about” route in app.py
- an about.html template inheriting from base.html
- the ‘Back To Recipe List’ link has been removed from recipe.html
Let’s create a navigation bar that will link to the about page and the index page. In base.html add the following content just inside the <body>
tag.
<div> <a href="/">Recipes</a> | <a href="/about">About</a> </div>
Once complete run the code and you’ll see that each page in the site now has a simple navigation bar including the new ‘About’ page.
Great work!
