Software Engineer working since 2008 with Ruby / Ruby on Rails, love a bit of Elixir / Phoenix.
I also poke through other people's code and make PRs for OpenSource Ruby projects that sometimes make it. Currently working at Juniper Education making code for UK schools.
I’m really not a fan of using GETs to call actions that create things like so.
<%= link_to image_tag('mini_icons/copy.png', :alt => 'Make a copy of this lesson'), copy_lesson_path(lesson), :method => :post %> <br/>
<%= link_to "Copy", copy_lesson_path(lesson), :method => :post %>
Despite using a form to pretend to be a link I much prefer this solution, because it actually enforces a POST to call the ‘copy’ action rather then pretending to be a post with a param { “_method” => “post” }
Ok so I decided to remove the bad version that was complaining.
sudo gem uninstall rspec -v 1.1.12
Gah, another error.
RubyGem version error: rspec(1.1.4 not = 1.1.12) (Gem::LoadError)
Ok so it must be something to do with version mismatches and there are always 2 gems required for RSpec with Rails. I guess rspec-rails looks for the nearest matched version of rspec
I’ve been musing over the past day or so on how best to assess whether our mailers are sending out messages that are likely to get caught by over zealous spam filters and render our e-mail campaigns useless.
One possible is to run all outbound e-mails through spam assassin, so for standard mailers we can just add a spec to check the content and for form mailers we can use it during validation before the final send off.
class TMail::Mail
def spam?
spam_filtered_body = %x[ echo '#{self.encoded}' | /usr/bin/spamassassin ]
return !! spam_filtered_body.match(/X-Spam-Status:\sYes/)
end
end
I’ve decided to go back to writing my own blog software. Simply Mephisto is too much for my needs and playing around with building my own Mephisto plugin just to create a plain old boring static page is just too time consuming. In fact I was able to knock up a new blog in less time.
My main issue with writing my own blog the last time was getting RedCloth to play nicely with CodeRay. Fortunately I stumbled upon the solution on GitHub.
It wasn’t quite what I wanted but gave me a good start and a few modifications later we have.
“./config/initializers/redcloth_with_coderay.rb”
module RedclothWithCoderay
SOURCE_TAG_REGEXP = /(<pre><code>(.+?)<\/source>)/m
# The RedCloth extension that performs the syntax highlighting.
def refs_syntax_highlighter(text)
text.gsub!(SOURCE_TAG_REGEXP) do |m|
all_of_it = $~[0]
lang = ($~[2] || :ruby).to_sym
code = $~[3].strip
highlighted = CodeRay.scan(code, lang).html(:wrap => :div, :css => :class, :line_numbers => :inline)
"<notextile>#{highlighted}</notextile>"
end
end
end
RedCloth.class_eval { include RedclothWithCoderay }
“./app/helpers/application_helper.rb”
module ApplicationHelper
def textilize(text)
RedCloth.new(text).to_html(:textile, :refs_syntax_highlighter)
end
end
Typically after getting this to work adding text after any code block was susequently hampered by a bug in RedCloth-4.1.9 which had me stumped for a whole day. I have reverted to RedCloth-4.1.1 in the meantime and its all lovely again.
It seems there are a few ways of grabbing the to address back, to just returns an array of e-mail addresses. to_addrs or [‘to’] actually return the full “to” address.
We’ve been having this irritating problem appearing intermitantly on ferret based searches.
A ActiveRecord::ConnectionTimeoutError occurred in users#search:
could not obtain a database connection within 5 seconds. The max pool size is currently 5; consider increasing it.
(druby:/localhost:9010) /usr/local/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/active_record/connection_adapters/abstract/connection_pool.rb:198:in `checkout'
We have 8 mongrels running, so ideally we’ll need at least one connection to the database per mongrel. Since we could conceivably have 8 concurrent connections to the site. You can up the connection pool size by adding the pool connection option to database.yml. A quick check in the console will demonstrate that it is now set
However, the problem persisted. I wasn’t aware that ferret itself maintains its own connection to the database so I’ll likely need to change this to 9. In fact we also have backgroundrb running which will also use its own connection. I think the lesson is to account for all the different processes that may be connecting the database at once when setting this option.
