search for: find_by_name

Hello, I upgraded my application from Rails 2 to Rails 3 and ran into a problem. In rails 2 I could use the english name of the record to find it like: Page.find_by_name("Welcome") even though the user chose German as the language (which of course showed the German welcome page. Eversince I switched to Rails 3 (default_locale still :en) I can''t find anything by giving the English name which sucks cause apparently when the user uses German it'...

...i, Let''s say I have an ActiveRecord::Base class and I want to be able to call a method on an Array of these items. For instance, perhaps there''s a class called Country and another called business, and I''d like to be able to do something like great_white_north = Country.find_by_name(''Canada'') canuck_enterprises = great_white_north.businesses countries = Country.find_by_name([''Canada'',''UK'',''Australia'') we_love_the_queen_enterprises = countries.businesses So I need to somehow extend the Array class I thin...

Hi, I have a def in my controller see below where i want to find the page object based on a parameter value and then use the page_id to then find all the contents that belong to that page in the same method. Controller def aboutus @page = Page.find_by_name(params[''About Us'']) @contents = Content.find(:all, :conditions => "page_id = #{@page.id}") end Page Model def self.find_by_name(pagename) find(:first, :conditions => "name = ''#{pagename}''") end I keep getting an error...

...rch_column_name => attributes[search_column_name]).first I found following solution on internet: https://github.com/rails/rails/issues/1974 Hence updated to: test = where(search_column_name => attributes[search_column_name]).all.to_a.first ...and this statement started working fine. But, find_by_name() is still failing with the same error. for eg. the below statement is not always working. test_lookup = find_by_identifier(lookup_str) || find_by_name(lookup_str) || find_by_abbreviation(lookup_str) statement is called under a function, defined in a model: def self.lookup(lookup_str) return ni...

I''d like to always add a condition to any version of "find" (e.g. Thing.find(), Thing.find_by_name(), Thing.find_by_whatever) so that in addition to whatever conditions are set, an additional condition is set :conditions=>"user_id=#{current_user.id}" I''d like to make sure that a user only sees/edits/creates entries in the database that have the user_id field set to their i...

I''m sure this has been asked before but a quick search on the web didn''t give me any hints.. I''d like to do this: @person = Person.find_by_name throw_page_not_found unless @person Anybody know how to do this, do I have to manually tinker with the response object? -- Posted via http://www.ruby-forum.com/.

Hi, While viewing part of a long list of records, the user may want to do a Find of a specific record (for example, find_by_name). The found record is then displayed using the list view. I''ve searched the wiki and couldn''t find a sample or information that will help directly in implementing this function. Any pointers? Thanks! gk -- Posted via http://www.ruby-forum.com/.

...he intermediate model is not completely dumb, and my scope trickery doesn''t make it any better. Now, let''s assume for a moment that participants was a plain has_many association. Then it would be possible to write things like m.participants.clear m.participants << Person.find_by_name(''Steve McKing'') m.participant_ids = params[:movie][:participants] With the given has_many :through, none of these work, as Role object won''t validate without a role type. Anyway, what I would like to write is m.participants.as(''actor'').clear m.partic...

Perhaps this is intentional, but it seems unlikely: class Person < ActiveRecord::Base belongs_to :school end p = Person.find(:first) p.school # nil p.school_id = School.find_by_name(''High School'').id p.school.name # High School p.school_id = School.find_by_name(''Primary School'').id p.school.name # High School <= Shouldn''t this be Primary School? p.school.id == p.school_id # false !!! Of course, p.school(:reload) works fine, but...

This is more of a design issue I''m wrestling with, and was wondering what other people are doing. I have a products table with status values of In Stock, Out of Stork or Discontinued. This is unlikely to change any time soon. Approach A, is to have thses actual values in the status column, at least the meaning is very apparent, yet querying for products with a specific status could

...has no PK/FK relation end A Segment is "linked" to Media by Media.name, which is the result of concatenating Segment.name and Segment.part.
