Setup

DB

(source code的tables)

1. download PostgreSQL 14 and pgAdmin (GUI介面)

2. Open pgAdmin4，在PostgreSQL/Database按右鍵 -> Create Database -> 命名為DB_travel

   

   • 首次下載pgAdmin 如果系統要求設定user password，則設為postgres

     

3. 在DB_travel 按右鍵，選Query Tool

   

   按下左上角資料夾按鈕(Open file)，在跳出的視窗中選取 db.sql 的路徑，按右下角Select

   

   在 Query Editor 中會自動出現新增資料與表格的queries，按下右上角的 Run 按鈕來執行。完成後Refresh Schema，即可看到所有表格

   

4. 為了在新增資料時，postgresql能夠依據已匯入的資料id來生成新id，需在Query Editor輸入以下指令並執行。

   SELECT setval('accounts_member_id_seq', (SELECT MAX(id) from public.accounts_member));
   SELECT setval('accounts_guide_id_seq', (SELECT MAX(id) from public.accounts_guide));
   SELECT setval('travelloapp_tour_id_seq', (SELECT MAX(id) from public.travelloapp_tour));
   SELECT setval('calc_order_id_seq', (SELECT MAX(id) from public.calc_order));
   SELECT setval('calc_tourist_id_seq', (SELECT MAX(id) from public.calc_tourist));
   

5. Open travello/settings.py, use the correct 'PASSWORD' in DATABASES.

Backend

All are done in the root directory

1. set virtual environment

   # for windows
   pip install virtualenv
   py -3 -m venv .venv
   .venv\scripts\activate

   # for mac(不確定是不是這樣)
   pip install virtualenv
   virtualenv venv
   source venv/bin/activate

2. install packages

   pip install -r requirements.txt
   # OR
   python -m pip install -r requirements.txt

3. start server

   python manage.py makemigrations
   python manage.py migrate
   python manage.py runserver
   # https://127.0.0.1:8000 in your browser

Create SUPER USER

python manage.py createsuperuser

• Set username & password as you like
• Go to http://127.0.0.1:8000/admin/ Add some testing data and check in pgAdmin to see if the tables have updated some new rows.
