checkbox can't convert Symbol into String in ruby on rails -


I want to use the checkbox below on my Ruby on Rail App: 

  & Lt; % = Check_box (: Monday, {: id = & gt; "Monday",: value => "Monday"})%>

But this is not the text of the checkbox that only shows "Monday" then I am using the code below to display text with the checkbox 

  & lt;% = Check_box: Monday, {: id = & gt; "Monday" ,: Price = & gt; "Monday"}, "Monday"%>

But he gave me an error below: 

  Icon can not be changed in the string

then what I want to display the text with the checkbox, please wait for me to answer, thank you
