Rails - passing a variable to string interpolation -

this what's in controller. i'm using devise , i'm trying show take user email , pass find specific family can display unique family controlled user.

i'm having issue string interpolation. if hard code email query works fine. want dynamic. help!

home_controller.rb    user_email = current_user.email   @unique_family = unit.where(:accountowner => '#{user_email}')

for string interpolation need use double quotes "", like:

name = 'some name' puts "hello #{name}" # => "hello name"

you see there name defined within single quotes, using puts , interpolating "hello" string name variable, necessary use double quotes.

to make where query can try with:

user_email = current_user.email @unique_family = unit.where(:accountowner => user_email)

in such case isn't necessary interpolate user_email "nothing" or trying convert string, unless want make sure what's being passed string, do:

@unique_family = unit.where(:accountowner => "#{user_email}")

or better:

@unique_family = unit.where('accountowner = ?', user_email)

that bind passed value user_email query.
