i am working on the existing code,i am new to ruby on rails ,i am not understanding this code and how is it working.why is 0..-6 given in month and 3...8 in year.

<% date_value = (Date::MONTHNAMES[monthname[0..-6].to_i]) + " " + (monthname[3..8]) %>         <% archive_string = "<li><a class='filter' href='/blog?month=" + monthname[0..-6] + "&year=" + monthname[3..8] + "'>" + date_value + "</a></li>" + archive_string %>       <% end %>       <%= raw archive_string %>

In that case I suggest you take a few days out to work right through a tutorial on rails, such as railstutorial.org, which is free to use online. That will give you a basic understanding of rails, and you will recover the time spent very rapidly.

To answer the question you first need to know what is in monthname, I suggest first you need to know what is in monthname. If you include something like <%= "monthname = #{monthname}" %> that will display whatever is in monthname. Next look at the docs for the String (I assume that monthname contains a string) to see what String[0..-6] and [3..8] do and to check if you <%= "[monthname[0..-6]" "(monthname[3..8]" %> for the cases that work and those that don't it will hopefully give you some idea. The docs for Range will tell you what [0..-6] do. Your code does look a little odd but I don't know what is in monthname, and the fact that it sometimes works means there must be some useful code there.
