Wiki

Project 1 for CS50’s Web Programming with Python and JavaScript.

Overview

A design of Wikipedia-like online encyclopedia.

Specifications

This project fulfills the following requirements:

Entry Page: Visiting /wiki/TITLE, where TITLE is the title of an encyclopedia entry, renders a page that displays the contents of that encyclopedia entry.
- The view gets the content of the encyclopedia entry by calling the appropriate util function.
- If an entry is requested that does not exist, the user is presented with an error page indicating that their requested page was not found.
- If the entry does exist, the user is presented with a page that displays the content of the entry. The title of the page includes the name of the entry.
Index Page: Updates index.html such that, instead of merely listing the names of all pages in the encyclopedia, user can click on any entry name to be taken directly to that entry page.
Search: Allowing the user to type a query into the search box in the sidebar to search for an encyclopedia entry.
- If the query matches the name of an encyclopedia entry, the user is redirected to that entry’s page.
- If the query does not match the name of an encyclopedia entry, the user instead is taken to a search results page that displays a list of all encyclopedia entries that have the query as a substring. For example, if the search query were ytho, then Python appears in the search results.
- Clicking on any of the entry names on the search results page takes the user to that entry’s page.
New Page: Clicking “Create New Page” in the sidebar takes the user to a page where they can create a new encyclopedia entry.
- Users are able to enter a title for the page and, in a textarea, are able to enter the Markdown content for the page.
- Users are able to click a button to save their new page.
- When the page is saved, if an encyclopedia entry already exists with the provided title, the user is presented with an error message.
- Otherwise, the encyclopedia entry is saved to disk, and the user is taken to the new entry’s page.
Edit Page: On each entry page, the user is able to click a link to be taken to a page where the user can edit that entry’s Markdown content in a textarea.
- The textarea is pre-populated with the existing Markdown content of the page. (i.e., the existing content is the initial value of the textarea).
- The user is able to click a button to save the changes made to the entry.
- Once the entry is saved, the user is redirected back to that entry’s page.
Random Page: Clicking “Random Page” in the sidebar takes user to a random encyclopedia entry.
Markdown to HTML Conversion: On each entry’s page, any Markdown content in the entry file is converted to HTML before being displayed to the user. Referring to python-markdown2 package to perform this conversion, installable via pip3 install markdown2.

Setup
