I''ve been playing around with some easier ways of specifying conditions in active record, and have come up with a little plugin that some may find useful. Currently active record finder and calculations methods can take a :conditions option with a string or array listing some sql conditions, eg: Animals.find :first, :conditions => "name = ''Tiger''" My

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

I am trying to allow for AND type ''find'' but to allow for simply a single set of find criteria. controller code... @vw_string = @vw_string1 = @vw_string2 = @vw_string3 = [] if params[:beg_intake_date] != "" then @vw_string1 = ["intake_date between ? and ?", params[:beg_intake_date], params[:end_intake_date] ] end if

Hello friends- There is a new release of the ez-where plugin. This plugin makes it easy to do complex ActiveRecord queries without writing any SQL. Ruby operators are mapped to SQL operators like so: foo == ''bar'' #=> ["foo = ?", ''bar''] foo =~ ''%bar'' #=> ["foo LIKE ?", ''%bar'']

I was brainstorming today about a smooth way to define conditions in an sql query, when the numbers of attributes increase, so does the uglyness. So instead of passing a hash, I thought you could specify the conditions directly in code. I hacked together some example code which actually turned out to work. The result is concise and pretty beutiful. def search(params) Ad.find(:all) do

Hi all, I have a question about this method in my User model: # Returns true for the (saved) user called "admin" def is_the_administrator true if save and name == "admin" end The method returns true if the user''s name is admin.

I have a form, with 3 fields, then in my controller I get the paramters to run a query but I don''t want to filter with paramters if they are nil or blank... I''m doing this @condition = '''' if(params.....) @condition = @condition + " myparamter = " + params[..... if(params.....) @condition = @condition + " myparamter = " +

Is there an easy (and secure) way to search your database when you don''t know the number of parameters ahead of time? I can see doing it by concatenating together an sql query, but hopefully rails provides a more elegant way to do this with ActiveRecord without making a ginormous switch statement? For example, lets say my search form has 4 different input boxes. I only want the query

Hi! It''s rather ruby question than rails... I have a single ''list'' action where i call paginate method. I can receive none, 1 or 2 variables that specify conditions for paginate method.

Hi there, I''m puzzled by this apparently simple query I can''t manage to reassemble using ez_where plugin. cond = Caboose::EZ::Condition.new :my_table do start_on < Time.now any {end_on > Time.now; end_on.nil?} end I keep getting the following result : >> cond.to_sql => ["my_table.start_on < ?

I''m having fun composing queries with ez_where, but am stuck on how to formulate the following using the ez syntax: (begin_date >= ? OR end_date >= ?) AND (description LIKE ? OR name LIKE ?) There are two clauses, each containing OR operators (the ez ''any'' syntax) but both clauses must evaulate to true for a match. Can anyone suggest the proper way to construct

I''ve been googling around trying to find some tips on creating tests for plugins. Am I correct in assuming that I''d have to have the tests as part of a rails app in order to test the plugin? I''d like to find a way to do standalone tests for the plugin. -- Posted via http://www.ruby-forum.com/.

Hi! Is there rails version of "where column in (value1, value2, ...)"? I know i could do OR many times, but this way is shorter. I''m ruby/rails newbie, so i have a problem with converting the hash, which i''m receving from the search form into the string for :conditions in find method. Could i instead of creating one, complicated (for me) query do something like
