Instead of tail -f, I generally use ‘less log/development’ then it’s a quick press of ‘F’ and less acts just like tail. The key difference is that if I see something important, I can press Ctrl+C and just page back and forth, search (’/’ + the term, ‘n’ to find the next occurance, etc.). It’s at great tool.

Yes, I agree RJS idea is really nice, but when you want to write unobtrusive JS code, it’s not the good solution.
What I don’t like with the current (Rails 2.X) RJS state, is the code they add on the view .

Some good tips, except I believe RJS are really cool! 99% people who complain about RJS templates just don’t understand how to write them properly. Also, HTML rendering in Helpers have their use. Most of the time you can do it really slick if you use content_tag and returning. Too much logic in the views makes them messy.

I certainly not avoid rails built in helpers! This is one part why Rails is so great!.
By do not rendering html in helpers I mean, instead of doing

def user_greetings(_user)
html = “

”
html += …
html += …
html += “

end

Or doing it content_tag …, I prefer using

def user_greetings(_user)
render :partial => “shared/greetings”, locals => {…}
end

The code is nicer, and If I need to reuse this piece of view, I can without repeating it.

Is it what you were looking for?

Would you care to elaborate on never rendering html in a helper? I use this trick and find it handy. All the other points make sense to me so I want to see if there is something I’m missing.

Do you also avoid rails built in helpers?

Hum, ruby-debug sounds nice, I’ll give it a try.

Nice post. I will try the query_reviewer and HAML. I would also suggest trying out the debugger gem ruby-debug. I couldn’t live without it
