I want to use an ButtonNavigation + MDList, but the list is just to see on half of the screen (see screenshot). Have can I display the list on the whole screen?

I want to add some boxes in body, but some bar of navigation specifically parallel to the boxes is not working.

I get this error when trying to show <%= @schedule.title %>, but when I do the same with <%= @lesson.title %> it is working fine for @lesson.

![undefined method `title' for nil:NilClass ]1

The flow is like this.

- A user signs up and creates a clinic, the clinic belongs to the user.
- A clinic has many practitioners and they belongs to the clinic.
- A practitioner has many lessons and schedules, and they belongs to the practitioner.

When I'm on the lesson show page, there is a link to a booking page. It's on this booking page that the error occours.

I know it's saying nil, but both lessons and schedules have been created for that specific practitioner.

Anybody knows why this is happening? I don't understand why I can access @lesson but not @schedule. Any help would be much appreciated.

I'm trying to use the Tempus Dominus Datetime picker in my app. Everything seems to work fine, but when I try to convert the submitted string into a datetime object in my controller, I get a TypeError (no implicit conversion of nil into String). I've also tried to puts the parameters into the logs, but get a blank line. The odd thing is, during the submission of the form, the parameters do seem to be present.

Here's all relevant code.
