syntax error, unexpected '}', expecting ':' Rails

Question

我想删除此部分： "company.html?#{token_url}&company=#{URI.encode(current_company.trylive_name)}"但出现错误，语法错误，意外的是“}”，期望为“：”

@iframe_statistics_url = "#{Gaston.amazon.cloudfront.host}/trylive_dashboard/iframe/#{current_user.has_role?(:administrator) ? "companies.html?#{admin_token_url}" : "company.html?#{token_url}&company=#{URI.encode(current_company.trylive_name)}"}" 

Answer 1

You can't use double quotes( " ) inside double quotes. You need to escape those quotes:

"Hello, "are you there?" # doesn't make sense in Ruby
"Hello, \"are you there?" # escaped double quotes inside the string

Answer 2

Try like this

val = current_user.has_role?(:administrator) ? "companies.html?#{admin_token_url}" : "company.html?#{token_url}&company=#{URI.encode(current_company.trylive_name)}"

@iframe_statistics_url = "#{Gaston.amazon.cloudfront.host}/trylive_dashboard/iframe/}#{val}" 

Or

g = "https://www.google.co.in/"

q = %[helo #{"world #{g}"}]

=> "helo world https://www.google.co.in/"

Try it

@iframe_statistics_url = %[#{Gaston.amazon.cloudfront.host}/trylive_dashboard/iframe/companies.html?#{current_user.has_role?(:administrator) ? admin_token_url : "#{token_url}&company=#{URI.encode(current_company.trylive_name)}"}]

@VtrKanna

@iframe_statistics_url = "#{Gaston.amazon.cloudfront.host}/trylive_dashboard/iframe/#{current_user.has_role?(:administrator) ? "companies.html?#{admin_token_url}" : "company.html?#{token_url}&company=#{URI.encode(current_company.trylive_name)}"}"

this is work fine but my problem is just to keep this part

@iframe_statistics_url = "#{Gaston.amazon.cloudfront.host}/trylive_dashboard/iframe/#{current_user.has_role?(:administrator) ? "companies.html?#{admin_token_url}"}" 

this is result an error
