How do I arrange data in alphabetic order?

Rails

Okay, here’s my question. I have data in a MySQL table and I want to
display the data in the alphabetical order of each row’s title. Right
now it displays it in the order it’s added. Is there a simple method I
can add to make it switch to alphabetical order, similar to how the
.reverse method? I’m really new, so this might not make sense…

Here’s the code as I have it now in my list.rhtml:

<% for recipe in @recipes %> <% end %>

<%= link_to h(recipe.title), :action => 'show', :id => recipe %>

<%= h(recipe.description) %>

 <%= link_to 'Edit', :action => 'edit', :id => recipe %>
<%= link_to 'Delete', :action => 'destroy', :id => recipe %>

This should do it.

<% for recipe in @recipes.sort{|a,b| a.title <=> b.title } %>

In your controller, change the line that looks like this:

@recipes = Recipe.find(:all, .....)

to include as an argument:

:order => 'title'

That should do it.

Jon G. … you are awesome… I struggled the entire day yesterday
figuring out how to sort a dynamic list based on categories
alphabetically while working on creating a styleguide based on ruby. I
have no experience working on ruby. When i found this link via google i
finally got my Eureka Moment. Thanks once again for providing the code.

The magic code that helped me was .sort{|a,b| a<==>b}

just to provide the entire code in context i used is a below

<% for c in @categories.sort{|a,b| a <=> b} %>

  • <%= c[0] %>

    • <% end %>

    i am wondering if i can use the same sorting filter in Jekyll…will
    give a try.

    thanks once again though
