## Installation
|
|
|
|
Most of the setup are the same as DMOJ installations. You can view the installation guide of DMOJ here: https://docs.dmoj.ca/#/site/installation.
|
|
There is one minor change: Instead of `git clone https://github.com/DMOJ/site.git`, you clone this repo `git clone https://github.com/LQDJudge/online-judge.git`.
|
|
|
|
Some frequent difficulties when installation:
|
|
|
|
1. Missing the `local_settings.py`. You need to copy the `local_settings.py` in order to pass the check.
|
|
2. Missing the problem folder in `local_settings.py`. You need to create a folder to contain all problem packages and configure in `local_settings.py`.
|
|
3. Missing static folder in `local_settings.py`. Similar to problem folder, make sure to configure `STATIC_FILES` inside `local_settings.py`.
|
|
4. Missing configure file for judges. Each judge must have a seperate configure file. To create this file, you can run `python dmojauto-conf`. Checkout all sample files here https://github.com/DMOJ/docs/blob/master/sample_files.
|
|
|
|
## Usage
|
|
|
|
Suppose you finished all the installation. Everytime you want to run a local server, follow these steps:
|
|
|
|
1. Activate virtualenv:
|
|
```bash
|
|
source dmojsite/bin/activate
|
|
```
|
|
|
|
2. Run server:
|
|
```bash
|
|
python manage.py runserver 0.0.0.0:8000
|
|
```
|
|
|
|
3. Create a bridge (this is opened in a different terminal with the second step if you are using the same machine)
|
|
```bash
|
|
python manage.py runbridged
|
|
```
|
|
|
|
4. Create a judge (another terminal)
|
|
```bash
|
|
dmoj 0.0.0.0 -p 9999 -c <path to yml configure file>
|
|
```
|
|
Here we suppose you use the default port 9999 for bridge in `settings.py`. You can create multiple judges, each should be in a seperate terminal.
|
|
|
|
**Optional**
|
|
|
|
5. Run celery worker (This is server's queue. It may be necessary in some functions)
|
|
```bash
|
|
celery -A dmoj_celery worker
|
|
```
|
|
|
|
6. Run a live event server (So everything is updated lively like in the production)
|
|
```bash
|
|
node websocket/daemon.js
|
|
```
|
|
|
|
## Deploy
|
|
Most of the steps are similar to Django tutorials. Here are two usual steps:
|
|
|
|
1. Update vietnamese translation:
|
|
- If you add any new phrases in the code, ```python manage.py makemessages```
|
|
- go to `locale/vi`
|
|
- modify `.po` file
|
|
- ```python manage.py compilemessages```
|
|
- ```python manage.py compilejsi18n```
|
|
|
|
2. Update styles (using SASS)
|
|
- Change .css/.scss files in `resources` folder
|
|
- ```./make_style && python manage.py collectstatic```
|
|
- Sometimes you need to `Ctrl + F5` to see the new user interface in browser.
