Introducing Flaskr |
|
================== |
|
|
|
This tutorial will demonstrate a blogging application named Flaskr, but feel |
|
free to choose your own less Web-2.0-ish name ;) Essentially, it will do the |
|
following things: |
|
|
|
1. Let the user sign in and out with credentials specified in the |
|
configuration. Only one user is supported. |
|
2. When the user is logged in, they can add new entries to the page |
|
consisting of a text-only title and some HTML for the text. This HTML |
|
is not sanitized because we trust the user here. |
|
3. The index page shows all entries so far in reverse chronological order |
|
(newest on top) and the user can add new ones from there if logged in. |
|
|
|
SQLite3 will be used directly for this application because it's good enough |
|
for an application of this size. For larger applications, however, |
|
it makes a lot of sense to use `SQLAlchemy`_, as it handles database |
|
connections in a more intelligent way, allowing you to target different |
|
relational databases at once and more. You might also want to consider |
|
one of the popular NoSQL databases if your data is more suited for those. |
|

If you're following the tutorial from a specific version of the docs, be |

sure to check out the same tag in the repository, otherwise the tutorial |
|
may be different than the example. |
