Requirements

Installation

Install Medojed:

$ git clone [email protected]:bogdanbodnar/medojed.git
$ cd medojed

Create virtual environment:

python3 -m venv env

Activate env:

$ source env/bin/activate

Check your version of pip and python :

(env) $ pip --version

Install dependencies from requirements.txt :

(env) $ pip install -r ./requirements.txt

Create and declare the database:

1. Create PostgreSQL database medojed: This step depends on your system. Project was tested with PostgreSQL version 9.6.2.
   • Ubuntu:

$ sudo -u postgres createdb medojed
$ sudo -u postgres psql medojed
>>>psql (9.6.2)
>>>Type "help" for help.
medojed=# ALTER USER postgres with encrypted password 'some_password';
>>> ALTER ROLE
medojed=# \quit

Done, go to step 2.

• Mac:

psql postgres

• Check if user postgres exists

postgres=# \du

• If yes, set his password (same as in config.py)

postgres=# \password postgres

• If not, create the user and give him necessary permissions

postgres=# CREATE ROLE postgres WITH LOGIN PASSWORD 'some_password'
postgres=# ALTER ROLE postgres CREATEDB;

• Confirm with \du and exit \q

• Now it's time to create the database

psql postgres -U postgres
postgres=> CREATE DATABASE medojed;

2. You may also need to change variables in config.py accordingly.
3. Run model.py (don't forget about the environment source env/bin/activate)

(env) $ python model.py

Run

Run Medojed from run.py:

(env) $ python medojed.py
