## I can't upload my data

Please check the following list.

- Filename: alphabetic file name is suitable.
- File format selection: File format radio button should be selected properly.
- When you are using JSON/JSONL: Confirm JSON data is valid.
  - You can use [JSONLint](https://jsonlint.com/) or some other tool (when JSONL, pick one data and check it).
- When you are using CSV: Confirm CSV data is valid.
  - You can use Excel or some tools that have import CSV feature.

3. **Logout from Django Admin site.** [You'll face login error without logout of Django Admin site](https://github.com/doccano/doccano/issues/723).

## I want to change user's or admin's password

For ordinary user:

1. Login to [Django Admin](https://djangobook.com/django-admin-site/) (URL: `/admin/`).
2. Open `Users` table.
3. Open user you want to change password.
4. In `Password` property, you'll see: `Raw passwords are not stored, so there is no way to see this user's password, but you can change the password using *this form*.` Click `this form` link.
5. Fill the form. Click `CHANGE PASSWORD` button.
6. **Logout from Django Admin site.** [You'll face login error without logout of Django Admin site](https://github.com/doccano/doccano/issues/723).

For the superuser account credentials, you have to set new password in the `docker-compose.dev.yml` and `docker-compose.prod.yml` files:

```yml
ADMIN_PASSWORD: "new_password"
```

## I want to change port number

On production, edit `docker-compose.prod.yml` file: change `80:80` substring in `nginx`/`ports` section to `<your_port>:80`.

On development, edit `docker-compose.dev.yml` file: change `8000:8000` substring in `backend`/`ports` section to `<your_port>:8000`.

## I want to update to the latest doccano image

1. Execute `git pull` to reflect the latest doccano.
2. Delete the volume that `doccano_node_modules`, `doccano_static_volume`, `doccano_venv` and `doccano_www`.
  **Do not delete `doccano_postgres_data` because it stores your projects data.**
3. Rebuild the doccano image.

The following commands are the procedure for 2~3.

```
❯ docker volume ls
DRIVER              VOLUME NAME
local               doccano_node_modules
local               doccano_postgres_data
local               doccano_static_volume
local               doccano_venv
local               doccano_www
❯ docker volume rm doccano_node_modules doccano_static_volume doccano_venv doccano_www
❯ docker-compose -f docker-compose.prod.yml build --no-cache
```
