  • Rails 2.3.5 table populated by fixtures at end of test run rather than at start

    - by rlandster
    I start with a test database containing the schema but with no data in the tables. I run a test like so cd test/ ruby unit/directive_test.rb I get failures indicating that the code found no data in the data tables. However, I look at the tables after running that test and the data is now in the the table. In fact, if I immediately run the test again I get no failures. So it appears that the fixture is being loaded into the table too late for one of my modules to find it. When are the fixtures loaded? After or before the app/model/*.rb files are executed? If it is after the models are executed is there a way to delay the loading? This issue is also relevant when running rake test:units since that task clears the test data after it finished.

  • (Rails) Creating multi-dimensional hashes/arrays from a data set...?

    - by humble_coder
    Hi All, I'm having a bit of an issue wrapping my head around something. I'm currently using a hacked version of Gruff in order to accommodate "Scatter Plots". That said, the data is entered in the form of: g.data("Person1",[12,32,34,55,23],[323,43,23,43,22]) ...where the first item is the ENTITY, the second item is X-COORDs, and the third item is Y-COORDs. I currently have a recordset of items from a table with the columns: POINT, VALUE, TIMESTAMP. Due to the "complex" calculations involved I must grab everything using a single query or risk way too much DB activity. That said, I have a list of items for which I need to dynamically collect all data from the recordset into a hash (or array of arrays) for the creation of the data items. I was thinking something like the following: @h={} e = Events.find_by_sql(my_query) e.each do |event| @h["#{event.Point}"][x] = event.timestamp @h["#{event.Point}"][y] = event.value end Obviously that's not the correct syntax, but that's where my brain is going. Could someone clean this up for me or suggest a more appropriate mechanism by which to accomplish this? Basically the main goal is to keep data for each pointname grouped (but remember the recordset has them all). Much appreciated. EDIT 1 g = Gruff::Scatter.new("600x350") g.title = self.name e = Event.find_by_sql(@sql) h ={} e.each do |event| h[event.Point.to_s] ||= {} h[event.Point.to_s].merge!({event.Timestamp.to_i,event.Value}) end h.each do |p| logger.info p[1].values.inspect g.data(p[0],p[1].keys,p[1].values) end g.write(@chart_file)

  • How can I call `update_attribute` for a list item in rails then actually update the html using jquery?

    - by Patrick Connor
    I want my users to be able to mark one or more items from an index view as "Active" or "Inactive" using a link. The text for the link should be state aware - so it might default to "Mark as Active" if the corresponding attribute was false or null, and "Mark as Inactive" if true. Once the user clicks the link and the attribute is updated in the controller, the link-text should update based on the new state. I am WAY off here, but this is a small sample of the code I have been trying... CONTROLLER ... respond_to :html, :js ... def update @item = Item.find(params[:id]) if @item.update_attributes(params[:item]) #Not sure of how to respond to .js here end end ... update.js.erb #how do I identify which element to update? $('#item[13456]').html("State aware text for link_to") VIEW - for item in @items = item.name = link_to "Mark as Active", item_path(item), :method => :put, :remote => true. :id => "item[#{item.id}]" I am happy to read any APIs, blogs, tutorials, etc. I just can't seem to get my hands/mind around this task. Any help or guidance is greatly appreciated!

  • How do I create the Controller for a Single Table Inheritance in Rails?

    - by Angela
    I am setting up the Single Table Inheritance, using ContactEvent as the Model that ContactEmail, ContactLetter, and ContactCall will all inherit. But I'm stumped on how to create the routing and the controller. For example, let's say I want to create a new ContactEvent with type Email. I would like a way to do the following: new_contact_event_path(contact, email) This would take the instance from Contact model and from Email model. Inside, I would imagine the contact_event_controller would need to know... @contact_event.type = (params[:email]) # get the type based on what was passed in? @contact_event.event_id = (params[:email]) #get the id for the correct class, in this case Email.id Just not sure how this works....

  • Ruby on Rails: How to create associated models on the fly ?

    - by Misha Moroshko
    I have the following models: class Product < ActiveRecord::Base belongs_to :brand belongs_to :model accepts_nested_attributes_for :brand, :model ... end class Brand < ActiveRecord::Base has_many :products has_many :models ... end class Model < ActiveRecord::Base has_many :products belongs_to :brand accepts_nested_attributes_for :brand ... end I have a problem to create a new product. Here is the relevant code in the controller: class ProductsController < ApplicationController ... def create @product = Product.new(params[:product]) if @product.save ... # Here is the error end ... end When user adds a new brand and a new model, params[:product] contains the following: "brand_attributes"=>{"name"=>"my_new_brand"} "model_attributes"=>{"model_no"=>"my_new_model"} and I got the following error: Mysql2::Error: Column 'brand_id' cannot be null: INSERT INTO `models` ... because model has a foreign key brand_id which is not set. I can't set it because the brand (like the model) is created on the fly when the product is created. I don't want to create the brand before the product, because then I the product has errors, I will need to delete the created brand. Then I tried to change params[:product] like this: "brand_attributes"=>{"name"=>"my_new_brand", "model_attributes"=>{"model_no"=>"my_new_model"}} but I end up with this: unknown attribute: model_attributes What would be the proper way to handle this ?

  • Is there a variable in Rails that equates to the template that is being rendered?

    - by Sean Ahrens
    I can do request.path_parameters['controller'] and request.path_parameters['action'], but is there anything like request.path_parameters['template'] so I can discern which template file (such as index.html.erb) is being rendered? I'm writing a method that automatically sets the body id to the template being rendered, for easy css manipulation: class ApplicationController < ActionController::Base ... after_filter :define_body_selector ... def define_body_selector # sets @body_id to the name of the template that will be rendered # ie. if users/index.html.erb was just rendered, @body_id gets set to "index" @body_id = ??? end ...

  • How do I create a point system in a Rails app that assigns points to users and non-authenticated-use

    - by codyvbrown
    I'm building a question and answer application on top of twitter and I'm hitting some snags because I'm inevitably dealing with two classes of users: authenticated and non-authenticated. The site enable users to give points to other users, who may or may not be authenticated, and I want to create a site-wide point system where the application stores and displays this information on their profile. I want to save this point data to the user because that would be faster and more efficient but non-authenticated users aren't in our system, we only have the twitter handle. So instead we display the points in our system like this: @points = point.all( :select => "tag, count(*) AS count", # Return tag and count :group => 'tag', # Group by the tag :order => "2 desc", :conditions => {:twitter_handle => params[:username]}) Is there a better way to do this? Is there a better way to associate data with non-authenticated users?

  • Rails: How do I run a before_save only if certain conditions are met?

    - by Shpigford
    I have a before_save method that I call that renames an uploaded image. before_save :randomize_file_name def randomize_file_name extension = File.extname(screen_file_name).downcase key = ActiveSupport::SecureRandom.hex(8) self.screen.instance_write(:file_name, "#{key}#{extension}") end That method is part of my Item model. That works great when I create a new item or need to update the image associated with an item...but the problem is that if I need to update an item but NOT the image, the randomize_file_name method still gets run and renames the file in the database (though not the file itself, obviously). So, I'm thinking I need to figure out a way to only run randomize_file_name if a file is included in the form submission...but I'm not sure how to pull that off.

  • Ruby on Rails: How can I authenticate different user types from one place?

    - by sscirrus
    Hi everyone! This is my first post on Stack Overflow. I am trying to build a system that authenticates three types of user with completely different site experiences: Customers, Employers, and Vendors. I'm thinking of using a polymorphic 'User' table (using AuthLogic) with username, password, and user_type (+ AuthLogic's other required fields). If this is a good way to go, how do I set this up so after authenticating an user_id with a user_type the standard way, I can direct the user to the page that's right for them? Thanks.

  • In Rails, how do you functional test a Javascript response format?

    - by Teflon Ted
    If your controller action looks like this: respond_to do |format| format.html { raise 'Unsupported' } format.js # index.js.erb end and your functional test looks like this: test "javascript response..." do get :index end it will execute the HTML branch of the respond_to block. If you try this: test "javascript response..." do get 'index.js' end it executes the view (index.js.erb) withOUT running the controller action!

  • Ruby on Rails: how to sort data in an array of active record objects right before iterating?

    - by DerNalia
    What is the best way to sort an array of active record objects by by a field? This array is a field of an object, link_pages, and I want it sorted by the field "sequence" <% @menu_bar.link_pages.each do |lp| %> <li id="page_<%= lp.id%>" class="ui-state-default"> <span class="ui-icon ui-icon-arrowthick-2-n-s"></span> <font size=5><%= lp.name %></font> | <%= link_to "remove", :controller => "admin/menu_bars", :action => :remove_page_from_menu, :page => lp.id, :id => @menu_bar.id %> </li> <% end %> maybe there is a way to do @menu_bar.link_pages.sort_by_sequence.each do .... that would be slick... but I just don't know.

  • How to find the right object in a Rails controller based on two variables?

    - by sscirrus
    Hi everyone, I have a three-table system: Companies, Customers, and Matches. The matches include, for example, private notes that each party makes about the other and some options they can set regarding the other. I have two sets of views centered around Companies and Customers for each party to look at the other and modify their notes and settings. # Customers Controller def show @customer = Customer.find(params[:customer]) @matchings = @candidate.matchings.find... @company = Company.find(params[:company]) end Obviously the @matchings is incomplete. Given that @matchings has fields customer_id and company_id, how do I find the right matching record? Thank you!

  • How to find the most recent associations created between two objects with Rails?

    - by Kevin
    Hi, I have a user model, a movie model and this association in user.rb (I use has_many :through because there are other associations between these two models): has_many :has_seens has_many :movies_seen, :through = :has_seens, :source = :movie I'm trying to get an array of the ten most recent has_seens associations created. For now, the only solution I found is to crawl through all the users, creating an array with every user.has_seens found, then sort the array by has_seen.created_at and only keep the last 10 items… Seems like a heavy operation. Is there a better way? Kevin
