Odd Capitilazions

Use single quotes when inserting strings

INSERT INTO hacks (ID, content, likes, dislikes, user_id, category_id) VALUES (2,'love yourself', 0,0, 1, 1);

SQL Tables Cheat Sheet: categories: ID, Name users: ID, username, displayname hacks: ID, content, likes, dislikes, user_id, category_id

A note on the users table

This table has three columns: ID, username, displayname.

ID is the primary key.
username acts as the name that either comes from Google OAuth or is entered as a login name (used to log in).
displayname actuallys acts as a displayname that is rendered in the hacks.

This was the query to create the hacks table

CREATE TABLE hacks ( _id SERIAL PRIMARY KEY, content varchar(1000), likes int, dislikes int, user_id int, category_id int, CONSTRAINT fk_user FOREIGN KEY(user_id) REFERENCES users(_id), CONSTRAINT fk_category FOREIGN KEY(category_id) REFERENCES categories(_id) );

CREATE TABLE categories ( _id SERIAL PRIMARY KEY, name varchar(1000) NOT NULL );

CREATE TABLE users ( _id SERIAL PRIMARY KEY, username varchar(50) NOT NULL UNIQUE, password varchar(50) NOT NULL, displayname varchar(50) UNIQUE );

The tables use sequences to generate the next primary key. The sequence is called 'hack_sequence' and is passed into the invocation of nextVal() as seen in apiController.js in the 'makeHack' func

hack_sequence Type | Start | Minimum | Maximum | Increment | Cycles? | Cache --------+-------+---------+---------+-----------+---------+------- bigint | 6 | 0 | 999 | 1 | yes | 1

user_sequence Type | Start | Minimum | Maximum | Increment | Cycles? | Cache --------+-------+---------+---------+-----------+---------+------- bigint | 2 | 0 | 999 | 1 | yes | 1

Things that don't do anything:

Password for app sign up or sign in (Google Oauth does work tho!)
- The username provided is stored in the database, you just don't need to pass in a password currently
Like + Dislike buttons are not connected to anything
Adding a new Hack does not automatically trigger a rerender of the page. Must go to category dropdown and reselect the category

Intended stretch feature

automatically render new hack on page (currently you have to navigate into another category and then return to the new hack category to see it rendered)
be able to add new categories
remove Oauth button on upper left when logged in using the app login

Branches

The main branch is pretty much empty. Dev is up to date.

If you want the 'client secret' in order to have administrative access to Google Oauth...

Venmo $420.69 to @sussybacca96 and leave a valid email address in the comment. You will be emailed the client secret once the funds have cleared.
