单引号内插值

Question

How can I perform interpolation within single quotes?

I tried something like this but there are two problems.

string = 'text contains "#{search.query}"'

1. It doesn't work

2. I need the final string to have the dynamic content wrapped in double quotes like so:

    'text contains "candy"' 

Probably seems strange but the gem that I'm working with requires this.

Answer 1

如果您不想转义双引号"text contains \\"#{search.query}\\""可以使用%{text contains "#{search.query}"} 。

Answer 2

'Hi, %{professor}, You have been invited for %{booking_type}. You may accept, reject or keep discussing more about this offer' % {professor: 'Mr. Ashaan', booking_type: 'Dinner'}

Answer 3

Use

%q(text contains "#{search.query}") 

which means start the string with single quote. Or if you want to start with double quote use:

%Q(text contains '#{text}')
