[Rails] Embedding link_to''s within text fetched from database.
Hi, I have the following problem that I can''t seem to figure out. I want to able to fetch some text from my database record in my controller, and then add two links within the text and then send that back to the view to get rendered so that the two links appear as links and when clicked on, they''d basically call the corresponding action for the link. Would anybody know how to go about doing this? How do you get a view to render the link out? Thanks and any help appreciated. -------------- next part -------------- An HTML attachment was scrubbed...

[Rails] Re: Embedding link_to''s within text fetched from database.
In your controller, you just take the @text from the database, copy it
to a new member variable @text_with_links, add a new link "by hand" to
that variable (@text_with_links += ''<a href="'' +
url_for(action =>
''...'') + ''">link</a>") and last
render @text_with_links instead of @text
at your view.
If the link was not to an action, you could use auto_link in your view.
<%= auto_link("Visit http://example.com") %> renders as
Visist <a href="http://example.com">http://example.com</a>

[Rails] Re: Embedding link_to''s within text fetched from database.
The problem is, if adding the links is dynamically determined, then in your view, you''d need some way to know that some particular database fetched text needs links while others don''t. If you do it in the controller, then your logic just goes there and you just embed the links when need be. thanks.
