Beginning_of_month

Rails
1

I trying to sort my posts by month at the way railscasts tells
http://media.railscasts.com/videos/029_group_by.mov

I only got the undefinded method error that beginning_at_month doesn’t
exists
undefined method `beginning_of_month’ for Time:Class

why is beginning_at_month an undefined method it’s also in the api

http://api.rubyonrails.org/classes/ActiveSupport/CoreExtensions/Time/Calculations.html#M000597

It’s an instance method (ie Time.now.beginning_of_month) but from the
error message it looks like you did Time.beginning_of_month

Okay i got an idea what was wrong
now it is

def archieven
@blogs = Blog.find(:all, :order => ‘created_at, id’)
@weblog_months = @blogs.group_by {|t| t.created_at.beginning_of_month
}
end

thanks for your help Frederick

For that it works but now i have not the same result as in the railscast

in my controller

def archieven
@blogs = Blog.find(:all)
@weblog_months = @blogs.group_by {Time.now.beginning_of_month }
end

the view

<% @weblog_months.each do |month, blogs| %>

<%= month.strftime('%b') %>

<% for @blog in blogs %> <%= link_to @blog.title, :controller =>'weblog', :action => 'show', :id => @blog %>
<% end %> <% end %>

The problem is that when i post a new post in another month it also
comes into the old month
there are no archives like into the railscast

What you want to do is group_by {|blog|
blog.created_at.beginning_of_month} (assuming created_at is the
relevant date)
