How to "output" / "reproduce" "blank lines" (stored in the database) in a rendered view file?
===

I am using Ruby on Rails 3.2.2 and I would like to know how to "output" / "reproduce" "blank lines" (stored in a database column Type TEXT) in a rendered view file. That is, in my database column Type TEXT I have stored the following (*note*: blank lines are really the ones shown in the code):

    Line 1
    Line 2
    
    Line 3
    
    
    Line 4
    ...

In order to make the outputted text to "follows" / "reflects" (in the above case) *spaces* accordingly to data stored in the database, for example, I would like to output some HTML code as like the following:


    Line 1<br/>
    Line 2<br/><br/>
    
    Line 3<br/><br/><br/>
    
    
    Line 4
    ...

... or something else.

How it is possible in a *correct* and *not dangerous* (for example, related to Cross-Site Request Forgery - CSRF) way?
