cep-moviereviewsite

Movie review site that also displays movie information. Made with flask, postgresql database hosted on heroku.

Task: Summative 3: Movie Review Website

Objectives

• Become more comfortable with Python.
• Gain experience with Flask.
• Learn to use SQL to interact with databases.

Overview

In this project, you’ll build a movie review website. Users will be able to register for your website and then log in using their username and password. Once they log in, they will be able to search for movie, leave reviews for individual movie, and see the reviews made by other people. You’ll also use the a third-party API by OMDb, another movie review website, to pull in ratings from a broader audience. Finally, users will be able to query for movie details and movie reviews programmatically via your website’s API.

Getting Started

PostgreSQL

For this project, you’ll need to set up a PostgreSQL database to use with our application. It’s possible to set up PostgreSQL locally on your own computer, but for this project, we’ll use a database hosted by Heroku, an online web hosting service.

1. Navigate to https://www.heroku.com/, and create an account if you don’t already have one.
2. On Heroku’s Dashboard, click “New” and choose “Create new app.”
3. Give your app a name, and click “Create app.”
4. On your app’s “Overview” page, click the “Configure Add-ons” button.
5. In the “Add-ons” section of the page, type in and select “Heroku Postgres.”
6. Choose the “Hobby Dev - Free” plan, which will give you access to a free PostgreSQL database that will support up to 10,000 rows of data. Click “Provision.”
7. Now, click the “Heroku Postgres :: Database” link.
8. You should now be on your database’s overview page. Click on “Settings”, and then “View Credentials.” This is the information you’ll need to log into your database. You can access the database via Adminer, filling in the server (the “Host” in the credentials list), your username (the “User”), your password, and the name of the database, all of which you can find on the Heroku credentials page.

Alternatively, if you install PostgreSQL on your own computer, you should be able to run psql URI on the command line, where the URI is the link provided in the Heroku credentials list.

Python and Flask

1. First, make sure you install a copy of Python. For this course, you should be using Python version 3.6 or higher.
2. You’ll also need to install pip. If you downloaded Python from Python’s website, you likely already have pip installed (you can check by running pip in a terminal window). If you don’t have it installed, be sure to install it before moving on!

To try running your first Flask application:

1. Download the summative3.zip from https://github.com/lorrainewang78/webprogramming/blob/master/summative3.zip and unzip it.
2. In a terminal window, navigate into your summative3 directory.
3. Run pip3 install -r requirements.txt in your terminal window to make sure that all of the necessary Python packages (Flask and SQLAlchemy, for instance) are installed.
4. Set the environment variable FLASK_APP to be application.py. On a Mac or on Linux, the command to do this is export FLASK_APP=application.py. On Windows, the command is instead set FLASK_APP=application.py. You may optionally want to set the environment variable FLASK_DEBUG to 1, which will activate Flask’s debugger and will automatically reload your web application whenever you save a change to a file.
5. Set the environment variable DATABASE_URL to be the URI of your database, which you should be able to see from the credentials page on Heroku.
6. Run flask run to start up your Flask application.
7. If you navigate to the URL provided by flask, you should see the text "Summative 3 TODO"!

OMDb API

OMDb (The Open Movie Database) is a RESTful webservice to obtain movie information, and we’ll be using their API in this project to get access to their review data for individual movies.

1. Go to http://www.omdbapi.com/.
2. Navigate to http://www.omdbapi.com/apikey.aspx and apply for an API key. Select "FREE! (1,000 daily limit). Fill up your email, first name, last name and a short description of your project. Note
3. You will be sent a verification link to activate your key via email. Click on the URL provided to activate your key.
4. You can now use that API key to make requests to the OMDb API documented http://www.omdbapi.com/#parameters. In particular, Python code like the below

import requests
res = requests.get("http://www.omdbapi.com/", params={"apikey": "<replace-with-your-own-key>", "t": "The+Godfather"})
print(res.json())

where apikey is your API key, will give you the review and rating data for the movie with the provided movie title. In particular, you might see something like this dictionary:

Requirements

Alright, it’s time to actually build your web application! Here are the requirements:

• Registration: Users should be able to register for your website, providing (at minimum) a username and password.
• Login: Users, once registered, should be able to log in to your website with their username and password.
• Logout: Logged in users should be able to log out of the site.
• Import: Provided for you in this project is a file called movies.csv, which is a spreadsheet in CSV format of 250 different movies. Each one has an movie title, release year, runtime, IMDB ID, and IMDB rating. In a Python file called import.py separate from your web application, write a program that will take the movies and import them into your PostgreSQL database. You will first need to decide what table(s) to create, what columns those tables should have, and how they should relate to one another. Run this program by running python3 import.py to import the movies into your database, and submit this program with the rest of your project code.
• Search: Once a user has logged in, they should be taken to a page where they can search for a movie. Users should be able to type in the title of a movie, IMDB ID, or Year of Release. After performing the search, your website should display a list of possible matching results, or some sort of message if there were no matches. If the user typed in only part of a title, your search page should find matches for those as well!
• Movie Page: When users click on a movie from the results of the search page, they should be taken to a movie page, with details about the movie: its title, IMDB id, year of release, runtime, IMDB rating, and any reviews that users have left for the movie on your website.
• Review Submission: On the movie page, users should be able to submit a review: consisting of a rating on a scale of 1 to 10, as well as a text component to the review where the user can write their opinion about a movie. Users should not be able to submit multiple reviews for the same movie.
• OMDB Data: On your movie page, you could also display (if available) the movie plot, genre, director, actors and poster, or any other relevant.
• API Access: If users make a GET request to your website’s /api/<imdb_id> route, where <imdb_id> is the IMDB id, your website should return a JSON response containing the movie’s title, year of release, imdb id, director, actors, imdb_rating, review count, and average score. The resulting JSON should follow the format:

{
    "title": "The Godfather",
    "year": 1972,
    "imdb_id": "tt0068646",
    "director": "Francis Ford Coppola",
    "actors": "Marlon Brando, Al Pacino, James Caan, Richard S. Castellano",
    "imdb_rating": 9.2
    "review_count": 28,
    "average_score": 9.8,
}

If the requested IMDB id isn’t in your database, your website should return a 404 error.

• You should be using raw SQL commands (as via SQLAlchemy’s execute method) in order to make database queries. You should not use the SQLAlchemy ORM (if familiar with it) for this project.
• In README.md, include a short writeup describing your project, what’s contained in each file, and (optionally) any other additional information the staff should know about your project.
• If you’ve added any Python packages that need to be installed in order to run your web application, be sure to add them to requirements.txt!

Beyond these requirements, the design, look, and feel of the website are up to you! You’re also welcome to add additional features to your website, so long as you meet the requirements laid out in the above specification!

Hints

• At minimum, you’ll probably want at least one table to keep track of users, one table to keep track of movies, and one table to keep track of reviews. But you’re not limited to just these tables, if you think others would be helpful!
• In terms of how to “log a user in,” recall that you can store information inside of the session, which can store different values for different users. In particular, if each user has an id, then you could store that id in the session (e.g., in session["user_id"]) to keep track of which user is currently logged in.

FAQs

For the API, do the JSON keys need to be in order?

Any order is fine!

AttributeError: 'NoneType' object has no attribute '_instantiate_plugins'

Make sure that you’ve set your DATABASE_URL environment variable before running flask run!

How to Submit

1. Submit using Summative Submission Link.
2. Record a 1- to 5-minute screencast in which you demonstrate your app’s functionality and/or walk viewers through your code. Upload that video to YouTube (as unlisted or public, but not private) or somewhere else.
