问题 I'm using devise in rails and I'm unable to logout of my user right now.

问题 I have a problem when trying to see a .pdf file (generated with PDFKit) unauthenticated, just going directly from a given url host/.../profile.pdf .

问题 I've set up a basic rails application to use twitter oauth gem and devise and have been able to log in a user. However, my problem is I've now got my app white-listed and I would like to get a user's email back in the response. I've followed all necessary steps on the twitter side (setting necessary permissions, URLS, and reset keys) and have tried passing both include_email=true and include_email=email as a params when I initiate the oauth sequence.

Therefore you would have to create a custom sessions_controller to handle your response. Take a look at the implementation on github to get an idea

Here's the code var timeZoneField = $("input[name='user_tz_offset']"); if (timeZoneField.length) { var browserDate = new Date(); var timeZoneOffsetSeconds = (browserDate.getTimezoneOffset() * 60) * -1;
