Found out you can't set the type to number

I am sure others have tried to do this but I thought I would add a not that tells ever one. You can’t use the type field in in rails 2.3. It is always set back to type => “text”

So if you are trying to set it to type => “number” it will not work. It always goes back to text. Sorry only way around this is to use a text_field_tag and set the type in that.

<%= text_field_tag :thing, type: "number" %>

Code above is the only way to set the type. in rails 3 you can just call number_field and it will work

Clarification with use of update_all

I would like to point out that if you are on rails 2.3.11 or lower you will not be able to run ledermann code.

Ledermann Code

user.messages.update_all(:read => true)

If you are running 2.3 or later it you will have to use James code

James Code

Message.update_all({:read => true}, {:id => user.messages})

thanks guys for all the code help

Usage

I use this in views when I need to join a array of objects from a sql request here is a basic version of what I mean.

Code example

<%= @blogs.map{ |blog| blog.comment }.join(“ | ”) %>

Recommendations

I would just use the path_to_image. I find that this is what works best. As it says above it can create problems.

Here is my code

Code example

def background_path(background)
  if background
    path_to_image background.file_name.normal
  else
    path_to_image "background_preview.jpg"
  end
end

def flavor_path(flavor)
  if flavor
    path_to_image flavor.file_name.normal
  else
    path_to_image("flavor_preview.jpg")
  end
end

basic but gets the job done and it does not have problem with my pre built paths which are called image_path
