语法错误，意外 '}'，期待 '：' Rails的

Question

我想删除这部分： "company.html?#{token_url}&company=#{URI.encode(current_company.trylive_name)}"但错误出现语法错误，意外 '}'，希望 '：'

@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

您不能在双引号内使用双引号（"）。你需要逃避这些报价：

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

Answer 2

尝试这样

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}" 

或者

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

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

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

试试吧

@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)}"}" 

这是做工精细 但我的问题是，只是为了保持这部分

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

这是导致错误
