[Rails] [ANN] ez_where plugin updated features.

Friends-

	I wanted to let people know that there is a new experimental release  
of this plugin. I would love feedback on syntax and features. There  
is now a full test suite with fixtures that covers all the available  
syntax. Look at the test suite for more syntax possibilities. There  
have been many additions since my last release. Fabien Atelier has  
been working on this with me and has added a bunch of great code.

	You can get it from here:

  http://http://brainspl.at/opensvn.csie.org/ezra/rails/plugins/dev/ 
ez_where/

	This is a request for feedback. I want to solidify the api soon so  
suggestions are welcome.

Here''s a snippet from the README:

Welcome to the new improved ez_where plugin for rails. This plugin is  
meant
to be used as a nice ruby like syntax for creating the :conditions  
part of an
ActiveRecord::Base.find. We also add the ActiveRecord::Base.ez_find  
method.
This method takes a block to simplify single and multi table queries.  
There
is now support for nested sub conditions using a few different  
techniques. The
default boolean used is ''AND''. any takes a subcondition block
and
uses ''OR''
to join them together.

@articles = Article.ez_find(:all, :include => :author) do |article,  
author|
   article.title =~ "%Foo Title%"
   author.any do
     name == ''Ezra''
     name == ''Fab''
   end
end

This issue a find with these :conditions => ["article.title LIKE ? AND
(authors.name = ? OR authors.name = ?)", "%Foo Title%",
"Ezra", "Fab"]

Basically here is the breakdown of how we map ruby operators to SQL  
operators:

foo == ''bar''           #=> ["foo = ?",
''bar'']
foo =~ ''%bar''          #=> ["foo LIKE ?",
''%bar'']
foo <=> (1..5)         #=> ["foo BETWEEN ? AND ?", 1, 5]
id === [1, 2, 3, 5, 8] #=> ["id IN(?)", [1, 2, 3, 5, 8]]
<, >, >=, <= et all will just work like you expect.

And here is a link to my blog with the entire README for your perusal:

[Rails] Re: [ANN] ez_where plugin updated features.

This plugin seems to be exactly what I am looking for.  However, I?ve 
been struggling this afternoon to get it to work. I should point out 
that I am a newbie to Rails.  I?ve created a search page using a model 
which does not have a corresponding table, as outlined here 
(http://rails.techno-weenie.net/tip/2005/11/19/validate_your_forms_with_a_ta
ble_less_model).   This bit works perfectly as the simple validation 
rules
work as expected.

The problem I am having is building the where condition.  I cannot seem 
to get the right syntax to get hold of the params value and build the 
condition.  I?m just trying to build a very simple example.  I have a 
textfield called postcode_area and all I want to do is create the 
following select (SELECT * FROM homes WHERE postcode LIKE 
''%postcode_area%''


The code in the controller is as follows:-

 # Search for a home using the information entered in index.
 def search
   @home_search = HomeSearch.new(params[:home_search])

   if @home_search.valid?
      @postcode_var = params[:home_search][:postcode_area]

      condition = Caboose::EZ::Condition.new do
        postcode =~ "%#{@postcode_var}%"
       # postcode =~ "%G77%"
      end

      @record_count = Home.count(condition.to_sql)
      if @record_count == 0
        flash_message ''There are no results for this search.  Please
try
again.''
        redirect_to :action => ''index''
      else
        @list_pages, @list_objects = paginate :homes, :per_page => 25,
        :conditions => condition.to_sql
        render :action => ''list''
      end
    else
      render :action => ''index''
    end
   end

Everything in the table is returned because the SQL used is SELECT * 
FROM homes WHERE (postcode LIKE ''%%'').  Here is the
development log
output:-

I know I am doing something really stupid but I have been going round in 
circles all afternoon.  I would really appreciate any assistance.

Harvey

[Rails] Re: [ANN] ez_where plugin updated features.

Harvey-

	Thanks for testing this out for me. It will be easy to do what you  
want. The problem you are having relates to the use of instance vars  
like @postcode_var. Since the condition is getting evaluated inside  
the Caboose::EZ::Condition block, @postcode_var won''t work and will  
return the sting you wanted as ''%%''. The way around this is to
just
use plain old local vars. SO what you want to do can be done like this:

postcode_var = params[:home_search][:postcode_area]

cond = Caboose::EZ::Condition.new do
     postcode =~ "%#{postcode_var}%"
end

@record_count = Home.count(cond.to_sql)


	Also you could do the same thing like this:

cond = Home.ez_condition { postcode =~ "%#{postcode_var}%" }

@record_count = Home.count(cond.to_sql)

	
	I need to add to the docs the fact that you can''t use @instance vars  
inside the conditions as they are not evaluated in the correct  
context. Try this solution out and see how it works for you and let  
me know.

Cheers-
-Ezra

[Rails] Re: [ANN] ez_where plugin updated features.

Ezra
 Thanks for all your help, its very much appreciated.  I made the changes you
 suggested but I am still having the same problem. The SQL comes out as
 SELECT COUNT(*) FROM homes WHERE (postcode LIKE ''%%'').

 The good news is that I have managed to add a select drop down.  The select
 is called care_type and contains two options, namely "nursing care"
and
 "residential care".  This works great giving me the correct SQL

 Here is the code:-

 Model===============================
 class HomeSearch < ActiveRecord::Base

   def self.columns() @columns ||= [];
     end

   def self.column(name, sql_type = nil, default = nil, null = true)
     columns << ActiveRecord::ConnectionAdapters::Column.new(name.to_s,
 default, sql_type.to_s, null)
   end

   column :care_type, :string
   column :postcode, :string
   column :room_type, :string
   column :min_price, :string
   column :max_price, :string

   validates_presence_of :care_type, :postcode
   #todo validation for min, max etc.
 end


 View - index rhtml search form============================
 <div id="right_side">
     <div id="right_side_border">
         <%= error_messages_for ''home_search'',
         { :header => ''Errors prohibited this home search from being
 processed''} %>

         <%= start_form_tag :action => ''search'' %>
         <b><label for="home_search_care_type">I am
looking for a home that
 provides </label></b>
         <%= select ''home_search'',
''care_type'', care_types, {:prompt=>"please
 select"} %>
         <p><b><label for="home_search_postcode">The
home should be in the
 </label>
         <%= text_field ''home_search'',
''postcode'',  :maxlength => 5 %>
 postcode area </b></p>


         <div id="extra_options_for_home_search"
style="display:none;">
         <p>The room should be <%= select
''home_search'', ''room_type'',
 room_types,
         {:prompt => "please select" } %></p>
         <p>The room should cost between ? <%= text_field
''home_search'',
 ''min_price'' %>
         and <%= text_field ''home_search'',
''max_price'' %> per week </p>
         </div>

         <div id="search_options">
         <%= link_to_function "Advanced Search Options",

Hi Harvey,

I''m one of the co-devs for the ez_where plugin. I don''t see
why your code
wouldn''t work, unless offcoarse, postcode_var is actually empty. 

Did you try a hardcoded value for postcode_var?

Thanks
I feel so stupid!  I''ve been looking at this all day and I
didn''t
release that I had

postcode_var = params[:home_search][:postcode_area]
instead of
postcode_var = params[:home_search][:postcode]

I''ll go and crawl under a rock.  Thank you

[Rails] Re: [ANN] ez_where plugin updated features.

Guys really loving your work.  All appears to be working as advertised but I
will be doing more testing tomorrow. One more question I hope you can help
me with.  My condition is becoming a rather long if/else statement.  I was
just wondering if there is a more ruby like way of handling this situation:-

cond = Caboose::EZ::Condition.new do
          postcode =~ "%#{postcode_var}%"

          if care_type_var == "nursing care"
              nursing == true
              if room_type_var == "single"
                single_nursing_charge <=> (min_price_var..max_price_var)
                single >  0
              elsif room_type_var == "single with ensuite"
                single_ensuite_nursing_charge <=>
(min_price_var..max_price_var)
                single_ensuite >  0
              elsif room_type_var == "twin"
                twin_nursing_charge <=> (min_price_var..max_price_var)
                twin >  0
              elsif room_type_var == "twin with ensuite"
                twin_ensuite_nursing_charge <=>
(min_price_var..max_price_var)
                twin_ensuite >  0
              elsif room_type_var == "multi"
                multi_nursing_charge <=> (min_price_var..max_price_var)
                multi >  0

                multi_ensuite_nursing_charge <=>
(min_price_var..max_price_var)
                multi_ensuite >  0
              end

          elsif care_type_var == "residential care"
             residential == true
             if room_type_var == "single"

                single_ensuite > 0
              elsif room_type_var == "twin"
                twin_residential_charge <=> (min_price_var..max_price_var)
                twin >  0
              elsif room_type_var == "twin with ensuite"
                twin_ensuite_residential_charge <=>
(min_price_var..max_price_var)
                twin_ensuite >  0
              elsif room_type_var == "multi"

                multi_ensuite_residential_charge <=>

                multi_ensuite >  0
              end
          end
     end

[Rails] Re: [ANN] ez_where plugin updated features.

Glad you like it. Instead of using if...elsif...elsif... you could use a
''case''
structure. Also, if you feel your condition becomes rather longwinded, 
you can always break the condition into multiple parts you then append 
them together; something like:

cond = Caboose::EZ::Condition.new
cond.postcode =~ "%#postcode_var}"

if care_type_var == ''nursing care''
  case room_type_var
     when ''single'':
        ...
     when ''single with ensuite''
        ...
  end
else
  ...
end

	Woah dude that is a big looking query ;-) Yeah like Fabien said I  
would split it up a bit and use case statements. I''m glad you like  
the plugin. Keep pushing it hard and try to break it ;-) Then we can  
pick up the pieces and make i better.

[Rails] Re: [ANN] ez_where plugin updated features.

Hey Harvey, I''m new to Ruby myself and still looking for good
idiomatic programming tips. I don''t have half the Rails knowledge of
Ezra and Fabien, but I can make a recommendation. This comes from a
great book by Martin Fowler called "Refactoring." I forgot the exact
title but it''s something like "Transform Nested Conditionals to
Polymorphism."

The idea basically is that any time you''ve got an action which is
executed differently depending on some condition, you''ve got
polymorphism. So you can make the whole thing much less effort, and
much much nicer to read, by taking out that room type var and instead
creating a Room object which knows its own type. Likewise, instead of
having two variables to track whether or not there''s nursing going on
(nursing = true / care_type_var == "nursing care"), you just have a
Guest var which knows whether or not the guest requires any kind of
nursing.

(If I didn''t suspect you were doing something connected to the care of
senior citizens I would say all this talk of nursing sounds a bit
kinky.)

Anyway, you end up with pretty much the same amount of code, but
instead of a long cascade of if/else statements, you encapsulate all
that stuff in objects, and it''s much easier to read it that way. The
stuff about residential/nursing goes in the Guest object, the stuff
about single/double goes in the Room object, and then you just have a
Charge object which gets sent to the Guest and the Room to be properly
added up or whatever.

Hope this helps...
Giles
