ruby on rails - Formatting populated textarea, carriage returns, newlines, and HAML -


When I use the text with the text \ r \ n (Carriage Returns - Newline), text Is improperly formatted [update: \ r \ nA textorte is generated after filling, I'm simply dragging from the database that was previously loaded. Also to note, I do not have this problem in the production environment. END UPDATE] For example: 

 % textarea = "Hello \ r \ n How are you?"

Comes out like this: 

  Hello how are you?

I am thinking that there can be something with HAML on what can someone help me? Note: If I use \ n \ r then it works fine, but it is technically incorrect and the id has to be done to reverse some compartments for proper performance.

Because attacks automatically trigger HTML source code, such as whitespace-sensitive tags such as Prescasonia and Whatsyas Content may be poor HTML Nullin organizations & amp; # X000A; With these tags, there is a solution to change the new lines, which uses the Himal code Haml :: help # search_or_pressress helpers

Generally, when you are using a tag, you will automatically do this for you (it can be customized using : Protect the option). For example, 

 % p% textarea = "foo \ nbar"

will be compiled 

  Lt; P & gt; & Lt; Text area & gt; Foo & amp; # X000A; Bar & lt; / Text field & gt; & Lt; / P & gt; However, if someone is building a helpful tag, hemat can not recognize it and therefore you have to call  Haml :: helpers # find_and_preserve . You can also use  ~ , which is similar to  = , apart from it automatically runs  find_and_preserve  on your input. To: 
 
 % p = find_and_preserve "texturea> fu \ n bert "  
 
 is identical 
 
 % p ~ "textarea> fu \ n bert   
 
 and renders 
 
  & lt; P & gt; & Lt; Textarea & gt; Fu & # x000a; Bar & lt; / Textarea & gt; & Lt; / P & gt;
