Have a rails 4.2 app running on AWS Elastic Beanstalk, using delayed_job OmniAuth and Koala to interact with Facebook. The app also offers multiple identities per user account (Facebook, Twitter, Email)
When user posts on the app, there's a "post to facebook" checkbox. If checked, it posts to user's wall. The app requests "publish_actions" up-front to allow this posting. This works today.
The desired behavior is to only request this additional "publish_actions" permission when the user tries to post to facebook. Looking for engineer to provide source code change to make this happen without breaking other parts of the app (e.g., non-Facebook login).
I will provide source code, but not direct server access. If any configuration changes are required, you will provide instruction and we will implement. Project needs to completed within one week of acceptance, and requires NDA.
