search for: arelatively

Hello all, I''ve recently been on a project where somewhere needs using case insensitive search(using UPPER(name) LIKE '''') and LIKE condition, I want to use arel and don''t use the old style string concatenation, can arel handle this? But I check on arel documentation, doesn''t seems have any upper/like operator, and check on arel source, under

Hello rubyonrails-core, I’ve been looking into possible changes to ActiveRecord / Arel to make it easier to write Rails applications that are free of SQL injection vulnerabilities, and in particular do so in a way that makes it easy for a code reviewer to verify that the app is safe from such bugs. The concern: ----------------- With the ActiveRecord API as is, it’s relatively easy to write

Hello, Arel::SelectManager (arel 2.0.9) uses following statement to insert a new record: @engine.connection.insert im.to_sql, ''AREL'', primary_key_name, primary_key_value But in DatabaseStatements insert ist defined as: insert(sql, name = nil, pk = nil, id_value = nil, sequence_name = nil) Actually, Arel::SelectManager does not use the sequence name. This leads to issues

Hi all, I''ve been playing around with Arel this week (actually outside of Rails) and found an issue with the clone implementation. I''ve added a patch and a testcase here: https://github.com/codders/arel/commit/660f706491ac012cb133554cffeaa6b9ae6046e9 and made a pull request against the rails/arel repo. I''ve also been playing around with support for ordering on

Hey, We hit a bug today because Arel::Visitors::ToSql is not threadsafe. Here is what is happening: Arel::Visitors::ENGINE_VISITORS is a cache of visitors instances. These instances are not inherently threadsafe because it contains state ''@last_column'', ''@connection'' that is shared between threads. The other variables ''@pool'',

I just posted this ticket in Lighthouse, but thought perhaps some discussion here would help point me in the right direction toward a solution. Here is a description of the problem (from the ticket - https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/6693-arel-union-does-not-support-order-or-limit) : > If we take two `ActiveRecord::Relations` and join them via `union`:

im a begginer in RoR and am using rails 3.2.3 and ruby 1.8.7 This forum has helped me to progress but I''m confused by one thing. My app is supposed to allow seaching for results depending on the check boxes that are checked. In my case, when the user checks a determined facility and clicks "search" the corresponding hotels with only those facilities should be returned. I can

I''m trying to figure out how to use ActiveRecord in conjunction with ARel. In particular, I''d like to replace my residual literal SQL with ARel, if only I could see how. Let''s take Article with multiple Versions as an example. With ARel alone, I can find articles with their latest versions like this articles = Article.arel_table versions = Article.arel_table

I have the following code: advertisements_arel = Advertisement.order("advertisements.id DESC").arel @advertisements = (params[:website_id].present? ? advertisements_arel.where(:website_id => params[:website_id]) : advertisements_arel).to_a It returns a struct Arel::SelectManager::Row data But I''d like it to return an array of Advertisement objects (like it would

Hi, I''ve search for documentations on queries with Arel 2 but there is pretty nothing and all I''ve found is for Arel 1 so I''ve run into NoMethodError: undefined method `[]'' for #<Arel::SelectManager:0x00000003f1b820> errors with join syntax. My query is barely simple but involve nesting queries. I have 4 tables. Assets, Deposits, Orders and OrderLines

I trying to create a select using Arel but I''m passing three parameters, I want to include the parameters only if they are different to nil or blank. Here is my method: def self.advsearch(summary_description, specialties, place) User.joins(:experience,:summary,:information) .where(Information.arel_table[:business].eq(false))

Firstly I''m sorry if this is off-topic but I think it''s a question that won''t be answered without good core knowledge. I have written a multiple self join query something like this: Person.find :all, :select => ''children_people_3.*'', :joins => { :children => { :children => :children } }, :conditions => { :people => { :name

Specifically, it''s not playing nice with any type that it doesn''t recognize, eg. SET, ENUM, etc.. Just trying to start my Rails 3.0.2 app I get a NotImplementedError exception "Column type `` is not currently handled" on the first SET field it encounters. Am I missing something here? Should I be disabling Arel for legacy tables or something? Thanks, Jason -- You

I want to write an arel engine to run an arel-based client against a RESTful back-end. I''ve seen people talk about it, but haven''t seen it actually done. Is it possible? What is the best place to find info/examples on how to do it? tx, Andy -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group. To post to this

Hello everybody, I have some troubles with uploading files in my Rails project. I use Rails 3, Ruby 1.9.2, rack 1.2.1, and both webrick / passenger on apache I was investigating and have isolated the strange behaviour on a simple empty project: view: <% form_tag({:action => ''upload''}, :multipart => true) do %> <%=text_field_tag :desc %>

I''ve got a table of events, and each event has a boolean attribute is_ten_event. On each row of the table is a chekbox to edit the value of is_ten_event, so that multiple rows can be edited with one submit. In order to allow boxes to be un-checked as well, the logic in the controller works like this get array of events from checkboxes that are ticked. make all events.is_ten_event =

I have a form that allows me to search a hotel by city or name and by rating through radio buttons. It all works. However, my hotel model has_one :facility, this facility model is composed by several boolean fields (for example, roomservice:boolean restaurant:boolean and so on) The question is, I want to add checkbox fields for each facility I have and in the search form, when the user selects

From having no errors with 3.0.2 I now see lots of these errors when running my tests. undefined method `visit_CoercibleString'' for #<Arel::Visitors::MySQL: 0x000001074f4298> Anyone know what this is? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi, I was very surprised by difference of delete_all on association vs model(delegated to relation). Given TaskFilter.has_many(:qualifiers, :class_name=>''TaskFilterQualifier'') TaskFilter.delete_all => one DELETE statement Without :dependent option on "qualifiers" association TaskFilter.first.qualifiers.delete_all => SELECT `task_filter_qualifiers`.* FROM
