Setup Instructions

1. Update the value of application in app.yaml to the app ID you have registered in the App Engine admin console and would like to use to host your instance of this sample.
2. Update the values at the top of settings.py to reflect the respective client IDs you have registered in the Developer Console.
3. Update the value of CLIENT_ID in static/js/app.js to the Web client ID
4. (Optional) Mark the configuration files as unchanged as follows: $ git update-index --assume-unchanged app.yaml settings.py static/js/app.js
5. Run the app with the devserver using dev_appserver.py DIR, and ensure it's running by visiting your local server's address (by default localhost:8080.)
6. (Optional) Generate your client library(ies) with the endpoints tool.
7. Deploy your application.

##Task 1 ###Explain in a couple of paragraphs your design choices for session and speaker implementation.

###Sessions Session model object is created to represent session entry in the datastore. SessionForm message object is created to handle outbound form message (user input).

Session entities are created as a child of Conference entities. Each Conference entity has a ancestor relationship with session entities.

###Speaker Speakers are created as entities.

##Task 3 ###Describe the purpose of 2 new queries and write the code that would perform them The two new queries I have created are "getConferenceSessionsByLocation" and "getSessionsInWishlistByType". "getConferenceSessionsByLocation" is used to get all sessions by area. For eg if a conference is happening in a city we could have multiple sessions and they might be happening at different locations. If you are attending a session at one of the session centers you could query for all the sessions happening near-by and attend if they are of interest to you. "getSessionsInWishlistByType" is used to get all the sessions in whishlist by type. User can query for type of sessions that they are interested in.

###How would you handle a query for all non-workshop sessions before 7 pm?

1. Filter query by typeOfSession for all non-workshop sessions
2. Filter query by startTime of the session to less than and equal to 7 pm

###What is the problem for implementing this query? The Datastore enforces some restrictions on queries. Using inequalities for multiple properties are currently disallowed. Therefore you cannot filter by typeOfSession and startTime.

###What ways to solve it did you think of? I have created "getConferenceSessionsByQuery" endpoints method for this query.

1. Firstly, I filter typeOfSession for all non-workshop sessions and fetch the results.
2. Then I use a for loop to iterate over the result and create a list of sessions for all the sessions before 7pm
