[Rails] GurusQ: Metal calling disparity-How to install metal in code

noreply@blogger.com (Sandip Ransing) — Sat, 03 Apr 2010 02:07:00 +0000

I have a simple class that I want to install as Rails Metal. I don't
want to put it into a file in app/metal for reasons I don't want to go
into. It looks like this, and handler is defined elsewhere.

class UrlFilter
ALLOW = [404]
DENY = [403]
def self.call(env)
handler.call(env["PATH_INFO"]) ? ALLOW : DENY
end
end

I've tried installing it like this :
ActionController::Dispatcher.middleware.use UrlFilter

but on the first request it crashes with :

The rails calling code looks like this :

def klass
if @klass.respond_to?(:call)
@klass.call
elsif @klass.is_a?(Class)
@klass
else
@klass.to_s.constantize
end
rescue NameError
@klass
end

def active?
return false unless klass

if @conditional.respond_to?(:call)
@conditional.call
else
@conditional
end
end

Notice when calling call no arguments are passed (twice!) ? Every metal
example I've seen defines the entry method as

def self.call(env)

yet this calling code doesn't pass any.

Whats going on ? How do I define and install a metal class in code ?

[Rails] Using Builders

noreply@blogger.com (Sandip Ransing) — Sat, 03 Apr 2010 01:30:00 +0000

I am using RoR 2.3, and have installed the builder gem

I have a line in a view as follows:

str_xml = render "fusioncharts/array_example/ss_array_data.builder",
{:arr_data => @arr_data}

Which does not set str_xml to anything.

I can confirm that in my controller I have @arr_data set up and
populated properly. (And in my controller, I have require 'builder'
at the top)

In my views folder, I have a folder set up under it as "fusioncharts/
array_example/" and the file ss_array_data.builder. (However, this may
be why str_xml is not being set -- when I go to the URL which would
invoke this view, I get "Missing template _ss_array_data.builder in
view path..." It will only render the page if I put the underscore
before the filename ss_array_data.builder, making it a partial).

What am I not understanding about builders that I cannot convert my
array @arr_data to str_xml ?

Thanks so much, RVince

Re: [spree-user] Re: User Personalisation of Products

noreply@blogger.com (Sandip Ransing) — Sat, 03 Apr 2010 01:28:00 +0000

A quick browse through your code shows that you can set options for a
product, but where were you planning on storing the information from
the user? I don't see any changes to the line_items table (or a
separate table), etc to store the personalization input from the user.

It also appears that each product can only have a single
personalization option. Is this your goal?

I have the need for something similar, but I need multiple
personalization options per product, and it needs to support more
options than a single text field (some "personalization" needs to be
radio buttons, select boxes, etc).

I would also merge your migrations right now while nobody is really
using the code. The way your migrations are currently written, if
someone was using a version that used the :personalisation_options
column inside products or variants, those changes would be lost when
you ran the 20100320220929_add_personalisable.rb migration since you
don't alter the name of the column, you drop it then re-create it. Of
course during the drop you lose any data that was entered by the admin
in that column. I assume that you are making the assumption that
nobody is using that previous version so it is ok to make the drop,
but if that's the case then you may as well clean up the migrations to
create the proper column to begin with. (Just my $0.02 on the
migrations)

[Rails] Re: Best way of sorting/grouping objects

noreply@blogger.com (Sandip Ransing) — Sat, 03 Apr 2010 00:51:00 +0000

By any chance do you have a model named PageType? If you, you could
set up a relationship between PageType and Page:

page.rb:
belongs_to :page_type

page_type.rb:
has_many :pages

Then display it with:

your_controller.rb:
@page_types = PageType.all

your_view.html.haml (or .erb, etc.)
- @page_types.each do |page_type|
%h1= page_type.name
%ul
= list_of page_type.pages do |page|
= page.name

If you don't already have a PageType model, or don't want to introduce
another model, you could probably use:

@page_types = Page.all(:order => 'page_type', :group => 'page_type')

and then play around with the result of that. (At least I think that's
correct… haha, sorry if it's not)

Good luck,
Angelo

I'm sure you can refactor code to fit almost anything into a single
new/edit partial :) But in my small experience the models are
different enough so that having different views for different models
makes the code more readable. That said, I almost always share new
and edit for a model in a partial:

e.g. new.html.erb
<%= render( :partial => "form", :locals => { :buttonname => 'Add' } )
%>

edit.html.erb
<%= render( :partial => "form", :locals => { :buttonname =>
'Update' } ) %>

_form.html.erb
<%= error_message_on :lab, :base %>
<% form_for ..., do |f| %>
<%= f.submit buttonname %>
...
<% end %>

Ryan Bates has great screencasts on this sort of thing, and I found
his Mastering Rails Forms http://www.pragprog.com/screencasts/v-rbforms/mastering-rails-forms

[Rails] Re: ScrAPI HTTPNoAccessError

noreply@blogger.com (Sandip Ransing) — Fri, 02 Apr 2010 23:38:00 +0000

I should also add -

Before I got the findurl method to just strip out any URLs with non
standard characters, I tried this line:

fullurl.gsub!(",","%2C")

Which replaced the commas with the URL friendlier code. This didn't work
either, nor did putting the whole lot inside a CGI.escape("")

The scrAPI documentation isn't particularly helpful in regards to what
format the URL needs to be in.

Sorry for my sloppiness--I understand. I guess my main question is why
would it show the correct time in the view on one machine, but not
another?

datetime.strftime("%A %B %d %Y %I:%M:%S %p")

Is different for each machine. I'm busily writing code to detect
where the user is, and adjusting the time shown in the view
accordingly, but I'm still mildly confused by why the two views show
differently.

[Rails] ScrAPI HTTPNoAccessError

noreply@blogger.com (Sandip Ransing) — Fri, 02 Apr 2010 23:31:00 +0000

Hi,

I'm having some problems using scrAPI. I'm getting some
HTTPNoAccessErrors on certain urls.

The program searches a page (http://en.wikiquote.org/wiki/List_of_films)
for all of the links on it that go to pages with movie quotes on them.

It then loops through the list, pulling out the details from each page
using this method:

def self.scrapemovies
Scraper::Base.parser :html_parser

urlarray = Movie.findurls

moviescraper = Scraper.define do
process "h1", :name => :text
process "p:nth-child(4)", :description => :text
result :description, :name
end

urlarray.each do |url|
fullurl = "http://en.wikiquote.org#{url}"
movieurl = URI.parse(fullurl)
data = moviescraper.scrape(movieurl)
movie = Movie.new
movie.url = fullurl
movie.name = data.name
movie.description = data.description
movie.save
end
end

This worked ok until it got to
http://en.wikiquote.org/wiki/20,000_Leagues_Under_the_Sea which gave me
the http error because it had a comma in the URL.

I wrote a little bit of code in the Movie.findurl method that just
stripped out any URLs with commas or parentheses in as a bodge just to
get things working, but I'm even getting the error on this URL:
http://en.wikiquote.org/wiki/27_Dresses which is very odd, because it
worked fine on the previous one which was :
http://en.wikiquote.org/wiki/25th_Hour.

I can't see the difference between them - I've tried manually visiting
the page, and it's fine.

I'm assuming that I need to do some sort of cleverer parsing on the URLs
(so that I can include the ones with commas and parentheses too).

Is the Scraper::Base.parser :html_parser line got anything to do with
it? I couldn't get the Tidy plugin to work properly, but I'm not sure
that it's got anything to do with the URL parsing anyway.

I'm totally stuck - thanks in advance for any help.

Jules.

Thanks again--the difference was that I had this in the development
config/enviroment.rb
config.time_zone = 'UTC'
But not in the production file. I uncommented it in the production
environment.rb just now, and lo and behold, that part is now working.

Except--I now remember I had in commented out of the production server
as another part of the code which displays the "created at" field for
a record was giving the wrong time. E.g. if I run date in a terminal

I get Fri Apr 2 17:13:05 CDT 2010

(Which is my time)
But for the created at for this record in the database I'm getting

2010-04-02 22:13:33

I don't seem to have that problem on my development machine (MacOS
laptop). The production server is a Redhat Linux machine.

Any idea how to "sync" created at and the system time on the
production server?

Again, many TIA,
Craig

[Rails] HELP!! Rake aborted! Can't modify frozen hash

noreply@blogger.com (Sandip Ransing) — Fri, 02 Apr 2010 22:26:00 +0000

Too bad even the trace doesn't say which hash is involved.

Sorry this post is long: am trying to provide enough context to be
meaningful.

Occurs _intermittently_ when rake jobs:work is pulling a command out of
delayed_jobs while my status observer is in the process of parsing a log
file for detailed results of the previous delayed_job denizen. I have
an observer class (in RAILS_ROOT/lib ) which listens for the events,
makes a copy of them and calls the owner class ( in apps/models ) which
then calls on the log parser (also in /lib) to do the actual work.
(Should both of those classes, the observer and the parser be in
app/models?)

Am due to deliver this application in a few days and this is killing it
(and me).

Am using DirectoryWatcher to look for flag files that indicate the start
and finish of the delayed_jobs.
That is started at the end of environment.rb like this:

require 'directory_watcher'
$scriptStatusObserver = ScriptStatusObserver.new
dirToWatch ="#{RAILS_ROOT}/tmp/flags"
$directoryWatcher = DirectoryWatcher.new( dirToWatch )
$directoryWatcher.glob= "*.flg"
$directoryWatcher.interval=(15)
$directoryWatcher.add_observer( $scriptStatusObserver )
$directoryWatcher.persist=("#{RAILS_ROOT}/tmp/flags/dw_state.yml")
$directoryWatcher.start

at_exit { $directoryWatcher.stop }

This code is outside of the run method (btw is that the best place or is
inside the run better?)

Here is the observer:
require 'script_run'

class ScriptStatusObserver

def initialize
@rcvdEvents = []
end

def update( *events )
begin
puts "#{__LINE__.to_s}: ScriptStatusObserver events:
\n"+events.to_yaml
cnt = 0

events.each do |e|
if e.to_s.match(/^\s*added/)
cnt = cnt + 1
@rcvdEvents << e
end
end

ScriptRun.new.catch_up( @rcvdEvents ) if cnt > 0

@rcvdEvents.clear

rescue
puts $!
end

end
end

Here is ScriptRun (it attaches to an associative table built with
has_many:through)

#require 'observer'

class ScriptRun < ActiveRecord::Base

set_table_name "scripts_runs"
belongs_to :script
belongs_to :run

def parse( result )
parser = LogParser.new
parser.parse(result)
end

def catch_up( events )
events.each do |e|
typ = e.type
path = e.path

thisMatch = path.match(/flags\/(\d+)_(\d+)_([\d\.]+)_(\w+)\.flg/)
run_id = thisMatch[1]
script_id = thisMatch[2]
ts = thisMatch[3]
status = thisMatch[4]

if e.to_s.match(/^\s*added/)
status_update( script_id, run_id, status, ts, path )
end
end
end

def status_update( script_id, run_id, status, ts, path )

scriptrun = ScriptRun.find(:first, :conditions => [ "run_id = ? and
script_id = ?", run_id.to_i, script_id.to_i ])

if scriptrun.kind_of?(ScriptRun)
currStatus = scriptrun.status
if not currStatus == 'completed'

scriptrun.update_attribute(:status, status)

if status == 'parse'
flag = File.new(path)
logSpec = flag.gets
flag.close

logName = File.basename(logSpec)
logPath = logSpec.sub(logName, '')

logName =~ /^(([\w_]+)_([\w]+)_(\d+))\.log$/
name = $1
basename = $2
runenv = $3
tsOrPid = $4

result = Result.new
result.log_path = logPath
result.basename = basename
result.name = name
result.script_id = script_id.to_i
result.run_id = run_id.to_i
if runenv == 'sit'
runenv = 'SIT3348'
end
result.application_environment_id =
ApplicationEnvironment.find(:first, :conditions => [
"nodename = ?", runenv]).id

parse(result)

if run_completed?( run_id )
myRun = Run.find(run_id.to_i)
if myRun.kind_of?( Run )
myRun.update_attribute( :completed, Time.now.to_f )
end
end

end
end

else
puts "#{__LINE__.to_s}: ScriptRun.status_update: ScriptRun not
found for run #{run_id} script #{script_id} ts #{ts.to_s}"
end

File.delete(path)

end

def run_completed?( id )
scriptruns = ScriptRun.find(:all, :conditions => [ "run_id = ?",
id.to_i] )
scriptruns.each do |sr|
if not sr.status == 'completed'
return false
end
end
return true
end
end

LogParser is too long even for this post but it reads the script log and
pulls detailed information (counts and timings) out of the log and
writes to a details table. It also tallies and calculates averages and
rolls those up into summary tables for quicker access from the web
pages.

Here is the error trace:

I forgot that f.check_box adds a hidden field so even unchecked, the
condition will trigger. One way to get around that is to use lambda in
the named scope and adjust what condition gets included based on the
check box value:

named_scope :my_condition, lambda { |check| "1"==check ? {:conditions=>
"your sql condition here"} : {}}

[Rails] "new" form as partial?

noreply@blogger.com (Sandip Ransing) — Fri, 02 Apr 2010 21:27:00 +0000

Hi!

I think I'm trying to accomplish something very common, but I can't
find a way to do it.

Creating a certain type of database record is a very frequent task in
my application (or at least it should be ;-)). So I want to be able to
place the form for creating that database record in practically any
view, not just the /mymodel/new view.

I figured that this might be done using a partial, but since I'm
pretty new to rails, I don't get it one.

Can anybody point me to a tutorial for this problem?

I'm using rails 2.3.5.

Thank you!
Marian

[spree-user] Re: User Personalisation of Products

noreply@blogger.com (Sandip Ransing) — Fri, 02 Apr 2010 21:24:00 +0000

The admin side of my extension is now working: an admin can set a
product to be personalisable, and can then set personalisation options
against a product.

Now I would like to display these results of these options to
customers:

The product has a personalisable? attribute. The product may also have
many personalisation_options associated with it. Each
personalisation_option has name, title and max_length

Step 1 now has me a little flummoxed: I need to build fields on the
product page for each personalisation_option associated with a
product, rendered as a label with title as its contents, and a text
field that limits to the number of character specified in max_length.

How do I go about this in spree / rails?

For anyone interested in helping, the current extension can be found
in its current gestation at git://github.com/peachygifts/spree-personalisation.git

Thanks for your help!

Michael

[Rails] Re: Two controllers with create using the same model

noreply@blogger.com (Sandip Ransing) — Fri, 02 Apr 2010 21:10:00 +0000

Thanks a lot Colin,

First of all, I'm using Rails 2.3.5. and Ruby 1.8.7.
The generated HTML looks like this: <form method="post"
id="beiratkozok" action="/beiratkozas">
The option suggested by you: <% form_for :student, @student, :url =>
{:controller => 'beiratkozas', :action => "create" }, :html =>
{ :method => :post, :id => "beiratkozok" } do |f| %> gives the very
same result, so somehow the form_for assumes that controller is
'beiratkozas'. Maybe because the path is: Views/beiratkozas/
new.html.erb to the view that contains the form_for.

And works, since I have:

map.connect 'beiratkozok', :controller => 'beiratkozas', :action =>
'new'
map.connect 'hallgato/:id', :controller => 'beiratkozas', :action =>
'show'
map.connect 'beiratkozas', :controller => 'beiratkozas', :action =>
'create'

I know that map.resources :beiratkozas would be a more Rails like
approach, but it's more human readable for Hungarians if I use
meaningful Hungarian words.

The html is added since I need the ID for CSS, and I wanted a
meaningful word as ID, since it makes CSS easier to read. On the other
hand :method => :post was added since I saw something like that
somewhere, and it made sense, since I want to use the POST verb in
this case. Right?

Peter

P.S.: What do you mean putting my comments inline with the previous
post? I'm simply hitting reply.

OK. I'll put something basic together and someone who knows pixels can

The previous form values you want for re-initializing the form are
passed into your controller method in the params object. If you have
built your form around an object called @search like this:

form_for @search do |f|

you just need to initialize @search with the search values in params, in
the controller method (perhaps Controller#index), like this:

@search = Model.search(params[:search])

If you have fields that are not part of Model that you want to include
in the search and have those initialized to, define a named_scope in
Model, and use that named_scope in the form for @search. Then it will
also be part of the params search values and get initialized along with
the other, automatically generated named scopes that correspond to the
model fields.

For example, to add a check box that limits the search to rows with a
certain condition, you could define a named scope in Model.rb like this:

named_scope :my_condition, :conditions => "your sql condition here"

Then in the view form, you would include:
<%= f.label :my_condition, "Check to apply my condition" %>
<%= f.check_box :my_condition %>

This happens sometimes in my place. Looks like it may be some
