How to use embedded ruby in ActionMailer subject

I'm trying to use some embedded ruby in the subject line of an email coming from ActionMailer but keep getting different errors.

I couldn't find any documentation on the proper syntax. Any resources to fix this line of code?

mail(to: @user.email, subject: "Your Reservation Confirmation for" + @restaurant.name)

I've passed in all of the variables fine. I just need to see how I can combine text and these inputs.

Thanks

I don't know whether this is intentional, but apparently @restaurant.name is returning a number (as you clarified, you're getting a TypeError: no implicit conversion of Fixnum into String). Calling @restaurant.name.to_s will solve that.

As G.B mentioned in another answer, string interpolation like "...Confirmation for #{@restaurant.name}" works too, since it calls #to_s for you automatically.

I'm putting the solution into an answer, since we found it while clarifying in the comments.

There are two common ways to it:

First:(regarding rep)

"...Confirmation for" + @restaurant.name.to_s

Second: you can use string interpolation

"...Confirmation for #{@restaurant.name}"
