  • How to mix mongodb and a traditional db in Rails?

    - by Jonathan
    I am considering using MongoDB (mongo-mapper) for a portion of my rails application. I am not ready to go whole hog MongoDB because there are too many useful gems that depend on a traditional DB. That being said there are parts of my application that would be great to leverage a document database. Has anyone had success mixing the two approaches? How do you link activerecord models with mongomapper models? Thanks, Jonathan

  • Rails / ActiveRecord Modeling Help

    - by JM
    I’m trying to model a relationship in ActiveRecord and I think it’s a little beyond my skill level. Here’s the background. This is a horse racing project and I’m trying to model a horses Connections over time. Connections are defined as the Horse’s Current: Owner, Trainer and Jockey. Over time, a horse’s connections can change for a lot of different reasons: The owner sells the horse in a private sale The horse is claimed (purchase in a public sale) The Trainer switches jockeys The owner switches trainers In my first attempt at modeling this, I created the following tables: Horses, Owners, Trainers, Jockeys and Connections. Essentially, the Connections table was the has-many-through join table and was structured as follows: Connections Table 1 Id Horse_id Owner_id Trainer_id Jockey_id Status_Code Status_Date Change_Code The Horse, Owner, Trainer and Jockey foreign keys are self explanatory. The status code is 1 or 0 (1 active, 0 inactive) and the status date is the date the status changed. Change_code is and integer or string value that represent the reason for the change (private sale, claim, jockey change, etc) The key benefit of this approach is that the Connection is represented as one record in the connections table. The downside is that I have to have a table for Owner (1), Trainer (2) and Jockey (3) when one table could due. In my second attempt at modeling this I created the following tables: Horses, Connections, Entities The Entities tables has the following structure Entities Table id First_name Last_name Role where Role represents if the entity is a Owner, Trainer or Jockey. Under this approach, my Connections table has the following structure Connections Table 2 id Horse_id Entity_id Role Status_Code Status_Date Change_Code 1 1 1 1 1 1/1/2010 2 1 4 2 1 1/1/2010 3 1 10 3 1 1/1/2010 This approach has the benefit of eliminating two tables, but on the other hand the Connection is now comprised of three different records as opposed to one in the first approach. What believe I’m looking for is an approach that allows me to capture the Connection in one record, but also uses an Entities table with roles instead of the Owner, Trainer and Jockey tables. I’m new to ActiveRecord and rails so any and all input would be greatly appreciated. Perhaps there are other ways that would even be better. Thanks!

  • Rails 3 time output

    - by Oluf Nielsen
    Hi, I'm now working on my output of the feeds I'm taking in from some site. What I'm currently doing is Time, and i want it to be displayed in a maybe, little be special way.. like this.. today, 14:12 yesterday, 15:34 27/12, 15:24 i have this in my code = news.entry_published.strftime("%d/%m, %H:%M") That gives me an error saying undefined method `strftime' for "2010-12-30 19:26:00.000000":String And it dosn't do what i want with the days.. Edit: - @date = DateTime.strptime(news.entry_published, "%Y-%m-%d %H:%M:%S") = @date.strftime("%d/%m, %H:%M") Now works, and gives this output 30/12, 19:26 But i still have to check if it is today, yesterday or just another day. Cheers, Oluf.

  • not getting a page reload when submitting a form on a page

    - by Bob Walsh
    When showing a project, the user can add a decision via a form_for and its partial. Is there some way of avoiding reloading the page and just creating the record silently? In the controller method (adddecision) I have: respond_to do |format| if @decision.save format.html { redirect_to(@project) } format.xml { head :ok } else format.html { render :action => "show" } format.xml { render :xml => decision.errors, :status => :unprocessable_entity } end I've tried redirect_to(:back) etc - still getting a page reload.

  • How to use a nested form for multiple models in one form?

    - by Magicked
    I'm struggling to come up with the proper way to design a form that will allow me to input data for two different models. The form is for an 'Incident', which has the following relationships: belongs_to :customer belongs_to :user has_one :incident_status has_many :incident_notes accepts_nested_attributes_for :incident_notes, :allow_destroy => false So an incident is assigned to a 'Customer' and a 'User', and the user is able to add 'Notes' to the incident. I'm having trouble with the notes part of the form. Here how the form is being submitted: {"commit"=>"Create", "authenticity_token"=>"ECH5Ziv7JAuzs53kt5m/njT9w39UJhfJEs2x0Ms2NA0=", "customer_id"=>"4", "incident"=>{"title"=>"Something bad", "incident_status_id"=>"2", "user_id"=>"2", "other_id"=>"AAA01-042310-001", "incident_note"=>{"note"=>"This is a note"}}} It appears to be attempting to add the incident_note as a field under 'Incident', rather than creating a new entry in the incident_note table with an incident_id foreign key linking back to the incident. Here is the 'IncidentNote' model: belongs_to :incident belongs_to :user Here is the form for 'Incident': <% form_for([@customer,@incident]) do |f| %> <%= f.error_messages %> <p> <%= f.label :other_id, "ID" %><br /> <%= f.text_field :capc_id %> </p> <p> <%= f.label :title %><br /> <%= f.text_field :title %> </p> <p> <%= label_tag 'user', 'Assign to user?' %> <%= f.select :user_id, @users.collect {|u| [u.name, u.id]} %> </p> <p> <%= f.label :incident_status, 'Status?' %> <%= f.select :incident_status_id, @statuses.collect {|s| [s.name, s.id]} %> </p> <p> <% f.fields_for :incident_note do |inote_form| %> <%= inote_form.label :note, 'Add a Note' %> <%= inote_form.text_area :note, :cols => 40, :rows => 20 %> <% end %> </p> <p> <%= f.submit "Create" %> </p> <% end %> And finally, here are the incident_controller entries for New and Create. New: def new @customer = current_user.customer @incident = Incident.new @users = @customer.users @statuses = IncidentStatus.find(:all) @incident_note = IncidentNote.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @incident } end end Create: def create @users = @customer.users @statuses = IncidentStatus.find(:all) @incident = Incident.new(params[:incident]) @incident.customer = @customer @incident_note = @incident.incident_note.build(params[:incident_note]) @incident_note.user = current_user respond_to do |format| if @incident.save flash[:notice] = 'Incident was successfully created.' format.html { redirect_to(@incident) } format.xml { render :xml => @incident, :status => :created, :location => @incident } else format.html { render :action => "new" } format.xml { render :xml => @incident.errors, :status => :unprocessable_entity } end end end I'm not really sure where to look at this point. I'm sure it's just a limitation of my current Rails skill (I don't know much). So if anyone can point me in the right direction I would be very appreciative. Please let me know if more information is needed! Thanks!

  • Reloading Rails Directories on Change for Dev: Not Lib!

    - by yar
    I have checked out several questions on this, including all of those you see next to the question. Unfortunately, I'm not working with a plugin, and I don't want to work in lib. I have a directory called File.join(Rails.root, 'classes') and I'd like the classes in this directory to reload automatically in dev. In my environment.rb I have this line config.load_paths << File.join(Rails.root, 'classes') which works fine and blows up if the path isn't there. The reloading line in my development.rb also works fine require_dependency File.join(Rails.root, 'classes', 'blah.rb') which blows up if the file is not there (a good sign). However, the file doesn't reload. This all works if the file is in the root of lib and I use the require_dependency line, but my whole point is to get stuff out of lib as suggested here.

  • How to validate presence of an uploaded file in rails?

    - by brad
    I'm playing around creating a rails file uploader and have struck a problem that should have an obvious solution. How do I check that a file has been selected in my form and uploaded? Here is my new.html.erb view <h2>Upload File</h2> <% form_for(@upload_file, :url => {:action => 'save'}, :html => {:multipart => true}) do |f| %> <%= f.error_messages %> <p> <%= f.label :file -%> <%= f.file_field :upload -%> </p> <p> <%= f.label :description %> <%= f.text_field :description %> </p> <p> <%= f.label :file_type %> <%= f.select :file_type, ["XML Data"] %> </p> <p><%= f.submit 'Upload File' %></p> <% end %> and here is my upload_file.rb model class UploadFile < ActiveRecord::Base validates_presence_of :description validates_presence_of :file_type validates_presence_of :upload def upload=(upload_file_field) self.name = "#{Time.now.strftime("%Y%m%d%H%M%S")}_#{upload_file_field.original_filename}" File.open("#{RAILS_ROOT}/public/upload/#{self.name}", "wb") { |f| f.write(upload_file_field.read) } end end If I use this as shown here, the validation validates_presence_of :upload always fails and I am returned to my form with an error message. I'd be very grateful if someone could explain how to do this validation correctly, and I'd be even more grateful if they could explain why it works. Thanks.

  • Treetop: parsing single node returns nil

    - by Matchu
    I'm trying to get the basic of Treetop parsing. Here's a very simple bit of grammar so that I can say ArithmeticParser.parse('2+2').value == 4. grammar Arithmetic rule additive first:number '+' second:number { def value first.value + second.value end } end rule number [1-9] [0-9]* { def value text_value.to_i end } end end Parsing 2+2 works correctly. However, parsing 2 or 22 returns nil. What did I miss?

  • Active Record two belongs_to calls to the same model

    - by ethyreal
    In linking a sports event to two teams, at first this seemed to make since: events - id:integer - integer:home_team_id - integer:away_team_id teams - integer:id - string:name However I am troubled by how I would link that up in the active record model: class Event belongs_to :home_team, :class_name => 'Team', :foreign_key => "home_team_id" belongs_to :away_team, :class_name => 'Team', :foreign_key => "away_team_id" end Is that the best solution? In an answer to a similar question I was pointed to single table inheritance, and then later found polymorphic associations. Neither of which seemed to fit this association. Perhaps I am looking at this wrong, but I see no need to subclass a team into home and away teams since the distinction is only in where the game is played. I thought also about a has_many through association but that seems two much as I will only ever need two teams, but those two teams don't belong to any one event. event_teams - integer:event_id - integer:team_id - boolean:is_home Is there a cleaner more semantic way for making these associations in active record? Thanks

  • Background job with status in rails

    - by pepernik
    Hey. I would like to upload a file and then parse it. Because parsing can take up to 10min I installed delayed_job plugin and called parsing function through send_later function. I have to mention that this is an AJAX app. Imagine that you press an AJAX button that starts upload and after that the source is imported into the database. During the process I want to show the progress bar or message (importing...) and when it completes the task status changes to done. My question is: What is the best way to check for status of the process. What would you do? My idea is to have another controller actions "status" which look into the database and provide the right status.

  • How do I debug this javascript -- I don't get an error in Firebug but it's not working as expected.

    - by Angela
    I installed the plugin better-edit-in-place (http://github.com/nakajima/better-edit-in-place) but I dont' seem to be able to make it work. The plugin creates javascript, and also automatically creates a rel and class. The expected behavior is to make an edit-in-place, but it currently is not. Nothing happens when I mouse over. When I use firebug, it is rendering the value to be edited correctly: <span rel="/emails/1" id="email_1_days" class="editable">7</span> And it is showing the full javascript which should work on class editable. I didn't copy everything, just the chunks that seemed should be operationable if I have a class name in the DOM. // Editable: Better in-place-editing // http://github.com/nakajima/nakatype/wikis/better-edit-in-place-editable-js var Editable = Class.create({ initialize: function(element, options) { this.element = $(element); Object.extend(this, options); // Set default values for options this.editField = this.editField || {}; this.editField.type = this.editField.type || 'input'; this.onLoading = this.onLoading || Prototype.emptyFunction; this.onComplete = this.onComplete || Prototype.emptyFunction; this.field = this.parseField(); this.value = this.element.innerHTML; this.setupForm(); this.setupBehaviors(); }, // In order to parse the field correctly, it's necessary that the element // you want to edit in place for have an id of (model_name)_(id)_(field_name). // For example, if you want to edit the "caption" field in a "Photo" model, // your id should be something like "photo_#{@photo.id}_caption". // If you want to edit the "comment_body" field in a "MemberBlogPost" model, // it would be: "member_blog_post_#{@member_blog_post.id}_comment_body" parseField: function() { var matches = this.element.id.match(/(.*)_\d*_(.*)/); this.modelName = matches[1]; this.fieldName = matches[2]; if (this.editField.foreignKey) this.fieldName += '_id'; return this.modelName + '[' + this.fieldName + ']'; }, // Create the editing form for the editable and inserts it after the element. // If window._token is defined, then we add a hidden element that contains the // authenticity_token for the AJAX request. setupForm: function() { this.editForm = new Element('form', { 'action': this.element.readAttribute('rel'), 'style':'display:none', 'class':'in-place-editor' }); this.setupInputElement(); if (this.editField.tag != 'select') { this.saveInput = new Element('input', { type:'submit', value: Editable.options.saveText }); if (this.submitButtonClass) this.saveInput.addClassName(this.submitButtonClass); this.cancelLink = new Element('a', { href:'#' }).update(Editable.options.cancelText); if (this.cancelButtonClass) this.cancelLink.addClassName(this.cancelButtonClass); } var methodInput = new Element('input', { type:'hidden', value:'put', name:'_method' }); if (typeof(window._token) != 'undefined') { this.editForm.insert(new Element('input', { type: 'hidden', value: window._token, name: 'authenticity_token' })); } this.editForm.insert(this.editField.element); if (this.editField.type != 'select') { this.editForm.insert(this.saveInput); this.editForm.insert(this.cancelLink); } this.editForm.insert(methodInput); this.element.insert({ after: this.editForm }); }, // Create input element - text input, text area or select box. setupInputElement: function() { this.editField.element = new Element(this.editField.type, { 'name':this.field, 'id':('edit_' + this.element.id) }); if(this.editField['class']) this.editField.element.addClassName(this.editField['class']); if(this.editField.type == 'select') { // Create options var options = this.editField.options.map(function(option) { return new Option(option[0], option[1]); }); // And assign them to select element options.each(function(option, index) { this.editField.element.options[index] = options[index]; }.bind(this)); // Set selected option try { this.editField.element.selectedIndex = $A(this.editField.element.options).find(function(option) { return option.text == this.element.innerHTML; }.bind(this)).index; } catch(e) { this.editField.element.selectedIndex = 0; } // Set event handlers to automaticall submit form when option is changed this.editField.element.observe('blur', this.cancel.bind(this)); this.editField.element.observe('change', this.save.bind(this)); } else { // Copy value of the element to the input this.editField.element.value = this.element.innerHTML; } }, // Sets up event handles for editable. setupBehaviors: function() { this.element.observe('click', this.edit.bindAsEventListener(this)); if (this.saveInput) this.editForm.observe('submit', this.save.bindAsEventListener(this)); if (this.cancelLink) this.cancelLink.observe('click', this.cancel.bindAsEventListener(this)); }, // Event Handler that activates form and hides element. edit: function(event) { this.element.hide(); this.editForm.show(); this.editField.element.activate ?

  • Passing an instance variable through RJS?

    - by Elliot
    Hey guys here is my code (roughly): books.html.erb <% @books.each do |book| %> <% @bookid = book.id %> <div id="enter_stuff"> <%= render "input", :bookid => @bookid %> </div> <%end%> _input.html.erb <% @book = Book.find_by_id(@bookid) %> <strong>your book is: <%=h @book.name %></strong> create.rjs page.replace_html :enter_stuff, :partial => 'input', :object => @bookid The problem here is that only create.js doesn't seem to work (though, if instead of passing the partial I passed "..." it does work, so I know its that there are instance variables in the partial that aren't being reset. Any ideas?) So the final question, is how do I pass an instance variable to a partial through the create.rjs file? p.s. I know I will have duplicate div IDs, I'm not worrying about that for now though. Best, Elliot

  • Saving multiple objects in a single call in rails

    - by CaptnCraig
    I have a method in rails that is doing something like this: a = Foo.new("bar") a.save b = Foo.new("baz") b.save ... x = Foo.new("123", :parent_id => a.id) x.save ... z = Foo.new("zxy", :parent_id => b.id) z.save The problem is this takes longer and longer the more entities I add. I suspect this is because it has to hit the database for every record. Since they are nested, I know I can't save the children before the parents are saved, but I would like to save all of the parents at once, and then all of the children. It would be nice to do something like: a = Foo.new("bar") b = Foo.new("baz") ... saveall(a,b,...) x = Foo.new("123", :parent_id => a.id) ... z = Foo.new("zxy", :parent_id => b.id) saveall(x,...,z) That would do it all in only two database hits. Is there an easy way to do this in rails, or am I stuck doing it one at a time?

In the Trophy model, which is an STI model, there's a trophy_type column. I want to return a list of users who have been awarded a specific trophy -- (trophy_type = 'GoldTrophy'). Users can be awarded the same trophy more than once. (I don't want distinct results.) Can I use a named_scope? How about chaining them? Or do I need to use find_by_sql? Either way, how would I code it?
