Flask-Bootstrap

Flask-Bootstrap packages Twitter's Bootstrap into an extension that mostly consists of a blueprint named 'bootstrap'. It can also create links to serve Bootstrap from a CDN.

Usage

Here is an example:

from flask.ext.bootstrap import Bootstrap

[...]

Bootstrap(app)

This makes some new templates available, mainly bootstrap_base.html and bootstrap_responsive.html. These are blank pages that include all bootstrap resources, and have predefined blocks where you can put your content. The core block to alter is body_content, otherwise see the source of the template for more possiblities.

The url-endpoint bootstrap.static is available for refering to Bootstrap resources, but usually, this isn't needed. A bit better is using the bootstrap_find_resource template filter, which will CDN settings into account.

If you are using custom code and still want to use files hosted from a CDN in production make sure you override the default CDN paths.

Macros

A few macros are available to make your life easier. These need to be imported (I recommend create your own "base.html" template that extends one of the bootstrap base templates first and including the the macros there).

An example "base.html":

{% extends "bootstrap_responsive.html" %}
{% import "bootstrap_wtf.html" as wtf %}

Forms

The bootstrap_wtf template contains macros to help you output forms quickly. The most basic way is using them as an aid to create a form by hand:

<form class="form form-horizontal" method="post">
  {{ form.hidden_tag() }}
  {{ wtf.form_errors(form, "only") }}

  {{ wtf.horizontal_field(form.field1) }}
  {{ wtf.horizontal_field(form.field2) }}

  <div class="form-actions">
     <button name="action_save" type="submit" class="btn btn-primary">Save changes</button>
  </div>
</form>

However, often you just want to get a form done quickly and have no need for intense fine-tuning:

{{ wtf.quick_form(form) }}

Configuration options

There are a few configuration options used by the templates:

Option	Default
BOOTSTRAP_USE_MINIFIED	True	Whether or not to use the minified versions of the css/js files.
BOOTSTRAP_JQUERY_VERSION	'1'	This version of jQuery is included in the template via Google CDN. Also honors BOOTSTRAP_USE_MINIFIED. Set this to None to not include jQuery at all. Note that non-minified Bootstrap resources are sometimes missing on bootstrapcdn, so it is best not to use it without turning on BOOTSTRAP_USE_MINIFIED.
BOOTSTRAP_HTML5_SHIM	True	Include the default IE-fixes that are usually included when using bootstrap.
BOOTSTRAP_GOOGLE_ANALYTICS_ACCOUNT	None	If set, include Google Analytics boilerplate using this account.
BOOTSTRAP_CDN_BASEURL	A dictionary set up with URLs to cdnjs.com.	The URLs to which Bootstrap and other filenames are appended when using a CDN.
BOOTSTRAP_CDN_PREFER_SSL	True	If the BOOTSTRAP_CDN_BASEURL starts with //, prepend 'https:' to it.
