Building Web Apps Using Flask and Neo4j

Learn cypher basics: use the match clause to pattern nodes and relationships, apply node labels and relationship types, assign identifiers, return results, and collect movies per person.

Learn how to pass Python variables to Flask templates with render_template, set up a templates directory, and render strings, lists, and lists of dictionaries in HTML.

Apply uniqueness constraints on user name, post id, and tag name by creating constraints on node label property pairs at application startup, producing indexes for efficient lookups.

Finish implementing user registration by defining a user class with find and register methods using graph to locate and create user nodes, encrypting passwords, flashing messages, and redirecting to login.

Finish implementing the like post feature by validating user login and creating a unique like relationship between user and post in Neo4j, then redirect to the referer page.

Deploy your Flask app to Heroku by creating a proc file and a requirements.txt, using the Heroku port from the port environment variable, and disabling debug mode.

Deploy to Heroku by pushing code, configuring graphene db add-on, and using an environment variable for the database URL. Confirm cloud deployment and test with a live app URL.
