How to add bootstrap wysiwyg into flask? – Twitter bootstrap

I want to using bootstrap wysiwyg in my Flask website.
I found this project flask-wysiwyg and followed the author’s advise, but it doesn’t work.

I would like to know:

• What is wrong?
• How should I solve this by myself?

Here is the code:

form.py

from .wysiwyg import WysiwygField

class PostForm(Form):
    article_title = StringField(u'title', validators=[Required(), Length(1, 64)])
    body = WysiwygField(u"txteditor", validators=[Required()])
    submit = SubmitField(u'submit')

view.py

# views.py
from .forms import PostForm
@main.route('/post', methods=['GET', 'POST'])
@login_required
def post():
    title = u'edit'
    form = PostForm()
    if  form.validate_on_submit():
        posts = Post(article_title=form.article_title.data,
                     body=form.body.data,
                     author=current_user._get_current_object())
        db.session.add(posts)
        flash(u'commit')
        return redirect(url_for('.doc'))
    return render_template('post-rich-text-edit.html', title=title, form=form)

post-rich-text-edit.html

{% extends "base.html" %}
{% import "bootstrap/wtf.html" as wtf %}
