# Basic CRUD: Flask & PostgreSQL

1. Activate __PostgreSQL__ server:

    

    ```bash

    $ cd C:\Program Files\PostgreSQL\10\bin

    $ psql -U postgres

      Password for user postgres: 

    ```

#

2. Create a database on PostgreSQL, my database name is __"lin_flask"__:

    

    ```bash

    postgres=#  CREATE DATABASE lin_flask;

    postgres=#  \l 

    postgres=#  \c lin_flask

    ``` 

#

3. Create a __"users"__ table on __"lin_flask"__ database:

    

    ```bash

    lin_flask=#  CREATE TABLE users(

                 id SERIAL PRIMARY KEY,

                 name VARCHAR(255),

                 age VARCAR(255)

                 );

    lin_flask=#  \d

    ``` 

#

4. Clone this repo. Insert your database URI to __database.yaml__ file, then install all the packages needed. In this project I'm using __flask__, __flask_cors__, __flask_mysqldb__, __Flask-SQLAlchemy__ & __psycopg2__:

    ```bash

    $ git clone https://github.com/LintangWisesa/CRUD_Flask_PostgreSQL.git

    $ cd CRUD_Flask_PostgreSQL

    $ pip install flask flask_cors Flask-SQLAlchemy psycopg2

    ```

#

5. Run the server file. Make sure your PostgreSQL server is still running. Your application server will run locally at __*http://localhost:5000/*__ :

    ```bash

    $ python app.py

    ```

#

6. Give a request to the server. You can use __Postman__ app:

    

    __See the opening screen (*home.html*)__

    ```bash

    GET /

    ```

    __Post a data to database:__ 

    ```bash

    POST /data

    body request: {name:"x", age:"y"}

    ```

    __Get all data & specific data by id:__

    ```bash

    GET /data

    GET /data/{:id}

    ```

    __Update a data by id__:

    ```bash

    PUT /data/{:id}

    body request: {name:"x", age:"y"}

    ```

    __Delete a data by id:__

    ```bash

    DELETE /data/{:id}

    ```

#
