In my rails application, people are supposed to submit “posts.” However, in the default scaffolding, there are some problems in the text input: not allowed HTML code, changing the line doesn’t work, etc. From what I’ve learned, I need to use a markdown-markup language to solve this issue. Is there a guide for me to follow to apply such language to solve my problem?
UPDATE: Here are my problems.
1) Every sentence is combined into one line even if I put a line space.
first line
second line
becomes
first line second line
2) I can’t make text bold, italicized, or hyperlink. Like in stackoverflow, user should easily put <b> and make bold text, ** to make italicized, etc. And URL address should automatically be translated to href link.
To do these, I thought I had to use markdown library. I could be mistaken, so I needed someone to guide me through. Railscasts on Markdown
Well, yes, new lines in HTML have no meaning. You need to replace line breaks with
<br>to preserve them in HTML. To automatically highlight links, you need to look for links in the text and wrap them in appropriate<a>tags. Finally, if you’re not filtering HTML tags, they should still be in there. It all depends on what you’re doing. Markdown is something entirely different, a special markup language that enables you to do the above while being easier to write than HTML. It depends on what you want to use.
