The last bit that we need is the view handler to add a new post. As we haven't created the application/posts/views.py module, let's do that. We'll need a Flask-WTForm class to handle/validate the new posts and a route handler to send and process the required fields, all hooked up to a new blueprint:

from flask import Blueprint, render_template, url_for, redirect, flash, current_app from flask.ext.login import login_required, current_user from flask.ext.wtf import Form from wtforms import StringField from wtforms.widgets import TextArea from wtforms.validators import DataRequired from sqlalchemy import exc from models import Post from application import db posts = Blueprint('posts', __name__, template_folder='templates') class CreatePostForm(Form): """Form for creating new posts.""" content = StringField('content', widget=TextArea(), validators=[DataRequired()]) @posts.route('/add', methods=['GET', 'POST']) @login_required def add(): """Add a new post.""" form = CreatePostForm() if form.validate_on_submit(): user_id = current_user.id post = Post(user_id=user_id, content=form.content.data) db.session.add(post) try: db.session.commit() except exc.SQLAlchemyError: current_app.exception("Could not save new post!") flash("Something went wrong while creating your post!") else: return render_template('posts/add.html', form=form) return redirect(url_for('users.feed'))
