Building a Simplified Replica of Instagram - Computer Science Assignment Help

Assignment Task:

Introduction 

In this assignment, you will be building a simplified replica of Instagram. You will be required to build a system where users can create posts. All posts must have an image attached to it (PNG or JPG only) and some text associated with it. There will be a system here where users can follow each other to see their posts. Eventually, this will lead to a timeline where the posts of a user and the posts of users they follow will be merged together. Users will also be permitted to comment on their own or other posts. 
Here the main task you will add-in is that you will have to deal with and manage multiple data storage mechanisms. The Blobstore will solely be used for managing your images, whereas the Datastore will be used to manage all other information. 

Coding Brackets
1. Bracket 1 
• Write the shell of an application that has a working login/logout service. 
• Create models of a user and posts using appropriate datatypes.

– This should show a reverse chronological timeline of all the user’s posts. 
– Should show numbers of how many they follow and how many are following them.
– If this is the profile of a different user this should show a follow/unfollow button. 
• Add in the ability to search for a user by username 
– Users should get a list of names back. 
– Clicking on a name will bring them to the profile for that user. 

4. Bracket 4
• Add the ability for a user A to follow another user B 
– This should put the B in A’s following list. 
– and A in B’s followers list. 
• Create a timeline on the main page that does the following 
– Pulls the last 50 posts in reverse chronological order from the current user and their following list. – Displays the last 50 posts in a vertical timeline. 

5. Bracket 5
• If the number of followers on the profile is clicked it should go to a new page showing the full list of followers. 
• If the number of following on the profile is clicked it should go to a new page showing the full list of following. 

6. Bracket 6 
• Add in the ability for users to add comments on any post. 
– Limit this to 200 characters maximum per post. – These should be shown in reverse chronological order. 
– Post should be shown as the username then the text they wrote. 

7. Bracket 7 
• In the main timeline only show the last 5 comments in each post 
– Add an expand button to posts that have more than 5 comments. 
– If the button is clicked it should go to a separate page or expand the columns in the current timeline.
