If you need to pass something back to the view (like the csrftoken) you can use `conn_params` for this.

[https://osc.github.io/ood-documentation/latest/reference/files/submit-yml/basic-bc-options.html](https://osc.github.io/ood-documentation/latest/reference/files/submit-yml/basic-bc-options.html)

```auto
# submit.yml
conn_params:
  - csrf_token

```

```ruby
# before.sh.erb
# this may actualy be case sensitive, so maybe csrf_token would work
export CSRF_TOKEN="<$= SecureRandom.uuid >"

```

Then you can use it directly in your view.html.erb like you use host/port and so on.

```auto
  document.cookie = "csrf-token=<%= csrf_token %>;

```

Once you export the variable in the before script, it should get written automatically to `connection.yml`. It may be problematic to write or rewrite that file, so it’s probably safer to use this mechanism `conn_params`.
