This week was quite an adventure in code deciphering. It was very helpful to walk through the simple.py file to understand how everything works together to render the website. Even more helpful was using branches to experiment with hacks. This is good for me since I like to break stuff.
To add an About page to my Simple blog, I made modifications to simple.py and layout.html, and created an about.html template. Borrowing from other lines of code and doing a bit of trial-and-error, the About page finally worked! When it came to pushing up these changes to heroku master, I ran into some problems. Apparently, I somehow generated several database URIs, which wasn't good and caused some conflicts. After I determined which of the several databases was the active one, I deleted the others. Finally, the pull worked and so did the push. Mission accomplished!
Here are the hacks that made it all happen:
simple.py
Added an @app.route for the About page, which includes authentication requirement.
@app.route("/about")
@requires_authentication
def view_about():
return render_template("about.html", now=datetime.datetime.now(), is_admin=is_admin(), preview=False)
layout.html
Added html code for an About menu link.
<li><p><a href="">About</a></p></li>
about.html
Created a new template for the About page.
{ % extends "layout.html" % }
{ % block title % }<title></title>{ % endblock % }
{ % block content % }
<h1>About</h1>
<p>Eventually, I will tell you all about this blog.</p>
<br/>
<a class="btn btn-inverse" href="">Back to Blog</a>
<br/>
{ % endblock % }
