  • Translate RoR Code to Java

    - by mnml
    Hi, for some reasons I am trying to translate the following RoR view code to a Java Groovy view: <% modulo_artists = @artists.length % 3 base = @artists.length / 3 base = base.ceil case modulo_artists when 0 cols = [base, base, base] when 1 cols = [base, base + 1, base] when 2 cols = [base + 1, base, base + 1] end counter = 0 %> <% id_hash = {"0" => "url('/images/actorsbg.png');", "1" => "url('/images/musiciansbg.png');", "2" => "url('/images/artistsbg.png') no-repeat; color: #FFF;", "3" => "url('/images/fashionbg.png')"} %> <div id="artists_<%=params[:artist_cat]%>" style="background: <%= id_hash[params[:artist_cat]] %>;" > <table border="0" width="660" height="164" cellpadding="0" cellspacing="0"> <tr valign="middle"> <% 3.times do |i| %> <td width="220" align="center" style="padding-right: 15px;"> <% cols[i].times do %> <h1><a href="/artists/show/<%= @artists[counter].urlname %>" ><%= @artists[counter].name %></a></h1> <% counter = counter + 1 %> <% end %> </td> <% end %> </tr> </table> </div> This is what I got so far: #{extends 'main.html' /} %{ modulo_artists = artists.size() % 3 base = artists.size() / 3 base = Math.ceil(base) if(modulo_artists == 0) cols = [base, base, base] else if(modulo_artists == 1) cols = [base, base + 1, base] else if(modulo_artists == 2) cols = [base + 1, base, base + 1] endif counter = 0 }% <div id="artists_${artist_cat}" style="background:${id_hash};" > <table border="0" width="660" height="164" cellpadding="0" cellspacing="0"> <tr valign="middle"> #{list items:1..3, as:'i'} <td width="220" align="center" style="padding-right: 15px;"> #{list items:cols[i]} <h1><a href="@{Artists.show(artists.get(counter).name.replaceAll(" ", "-"))}" >${artists.get(counter).name}</a></h1> %{ counter = counter + 1 }% #{/list} </td> #{/list} </tr> </table> </div> The idea is to keep the items organised in 3 columns like 1|0|1 4|5|4 or 5|4|5 for example

  • How Do I Add Value To All Previous Values In Array

    - by James
    Lets say I have the following array: my_array = [1, 5, 8, 11, -6] I need to iterate over this array and add the values prior to the current value together. An example will probably be easier to understand. I need to return an array that should look something like this: final_array = [1, 6, 14, 25, 19] I have tried doing something like this: my_array.collect {|value| value + previous_values } But obviously that doesn't work because I can't figure out how to get the previous values in the array. I am a programming noob so this might be easier than I am making it. I am pretty sure I need to use either collect or inject, but I can't seem to figure out how to do this. Any help would be appreciated.

  • Can rails test speed be increased?

    - by Sam
    Hi all, I'm a recent convert to TDD but as my codebase grows in size and complexity, I find myself waiting longer and longer periods for the framework to load every time I want to run a test. I am aware of rspec's spec_server but I'm using Test::Unit with shoulda. I tried Snailgun (http://github.com/candlerb/snailgun) but noticed very little increased in speed. I have also tried spork-testunit (http://github.com/timcharper/spork-testunit) but it's not fully compatible with my existing tests. The delay in running tests is a definite pain point and is putting me of TDD (at least with rails). Is anyone aware of any other options? thanks Sam

  • Where to put constants in Rails

    I have a few constants which are arrays that I don't want to create db's for but I don't know where to store the constants without getting errors. For example CONTAINER_SIZES = [["20 foot"],["40 foot"]] Where can I store this so all models and controller have access to this?

  • intelligent thin start with port alias for bash

    - by seaofclouds
    i would like a single alias (ts) which starts my local development server. the script should test for an open port starting at 3000 and use the first available port. additionally, some sites require a rackup file, making -R config.ru necessary. this script should check the current directory for the config.ru file and add that to the alias if present. currently, to start my local development environment, i run: alias ts="thin -R config.ru -p 3000 start" often, i need to run several servers to test different sites, so i've created additional aliases: alias ts1="thin -R config.ru -p 3001 start"

  • HAML-like syntax for non-HTML documents?

    - by Peter
    I love using HAML for HTML documents. It has clean syntax that's much more attractive than ERB. It works perfectly for HTML documents. What about for non-HTML? Such as, for example, an email or text document with certain automatically-substituted components? I've been falling back to ERB, but don't like the heavy syntax compared to HAML. Is there any way to use HAML for ordinary documents without having divs and html elements appear when % and . start a line? Or is there some alternative to both HAML and ERB that I should investigate?

  • file_field is not sticky in my Rails form

    - by Tony
    I have a pretty standard Rails form: <div> <h1>Create a New Listing</h1> <%- form_for @listing, :html => {:multipart => true} do |f| -%> <div><%= f.label :title, "Title:"%> <%= f.text_field :title %></div> <div> <%= f.label :image, "Image:" %> <%= f.file_field :image </div> <div> <%= f.label :sound, "Sound Clip:"%> <%= f.file_field :sound %><br /> </div> <div class="submit"><%= f.submit 'Post Listing' %></div> <%- end -%> </div> When a user chooses a file, but the form fails for validation purposes, he must always re-select the file. It is not sticky. Any suggestion on how to fix this? Thanks!

  • Rails has-and-belongs-to-many form question

    - by swilliams
    Sorry for the semi-generic title, but I'm still pretty new at rails and couldn't think of a succinct way to put the question. I have a basic habtm model setup: a Project has many Resources and a Resource can have many Projects. I have the database and models setup properly, and can do everything I need to via the console, but I'm having trouble translating it all into the view. On the show view for the Project, I want to be able to create a Resource and automatically assign it to the current Project. Here's my basic html: <p> <b>Name:</b> <%=h @project.name %> </p> <h2>Equipment</h2> <ul> <% @project.resources.each do |r| %> <li><%=h r.name %></li> <% end %> </ul> <h2>Add A Resource</h2> <% form_for(@project) do |f| %> <%= f.error_messages %> <p> Resource Name:<br /> <%= f.text_field :resources %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> Obviously, that form won't work, but I'm at a loss for what to do next. I've searched around for various examples, but haven't found one for what I'm trying to do here. One thing I've thought of was to change the form to be form_for(Resource.new) and include a hidden input of the @project.id. And then when the resource_controller handles the form, check for that id and go from there. That seems like an ugly kludge though.

    I'm trying to perform a search, order the results randomly, and only return a number of results, not all matches. Something like limit(2) I've tried using the Solr param 'rows' but that doesn't seem to do anything: @featured_articles = Article.search do with(:is_featured, true) order_by :random adjust_solr_params do |params| params[:rows] = 2 end end @featured_articles.total should be 2, but it returns more than 2 How can I get a randomized fixed number of results?

  • Sql query Error: Operand should contain 1 column(s) in rails

    - by dombesz
    Hi everyone, SELECT * FROM jobs WHERE (SELECT DISTINCT jobs.* FROM jobs, job_requests WHERE (jobs.user_id = 1) OR (job_requests.user_id = 1 AND job_requests.job_id = jobs.id)) This sql gives me Mysql::Error: Operand should contain 1 column(s). If i execute the select from the where clause it works SELECT DISTINCT jobs.* FROM jobs, job_requests WHERE (jobs.user_id = 1) OR (job_requests.user_id = 1 AND job_requests.job_id = jobs.id) Could somebody explain me why? This query is generated by rails activerecord so the main select is needed.

  • Keeping dates in order when using date_select and discarding year in Rails?

    - by MikeH
    My app has users who have seasonal products. When a user selects a product, we allow him to also select the product's season. We accomplish this by letting him select a start date and an end date for each product. We're using date_select to generate two sets of drop-downs: one for the start date and one for the end date. Including years doesn't make sense for our model. So we're using the option: discard_year => true To explain our problem, consider that our products are apples. Vendor X carries apples every year from September to January. Years are irrelevant here, and that's why we're using discard_year => true. However, while the specific years are irrelevant, the relative point in time from the start date to the end date is relevant. This is where our problem arises. When you use discard_year => true, Rails does set a year in the database, it just doesn't appear in the views. Rails sets all the years to 0001 in our app. Going back to our apple example, this means that the database now thinks the user has selected September 0001 to January 0001. This is a problem for us for a number of reasons. To solve this, the logic that I need to implement is the following: - If season_start month/date is before season_end month/date, then standard Rails approach is fine. - But, if season_start month/date is AFTER season_end month/date, then I need to dynamically update the database field such that the year for season_end is equal to the year for season_start + 1. My best guess is that I would create a custom method that runs as an after_save or after_update in my products model. But I'm not really sure how to do this. Ideas? Anybody ever had this issue? Thanks!

  • Can't mass-assign protected attributes -- unsolved issue

    - by nfriend21
    I have read about 10 different posts here about this problem, and I have tried every single one and the error will not go away. So here goes: I am trying to have a nested form on my users/new page, where it accepts user-attributes and also company-attributes. When you submit the form: Here's what my error message reads: ActiveModel::MassAssignmentSecurity::Error in UsersController#create Can't mass-assign protected attributes: companies app/controllers/users_controller.rb:12:in `create' Here's the code for my form: <%= form_for @user do |f| %> <%= render 'shared/error_messages', object: f.object %> <%= f.fields_for :companies do |c| %> <%= c.label :name, "Company Name"%> <%= c.text_field :name %> <% end %> <%= f.label :name %> <%= f.text_field :name %> <%= f.label :email %> <%= f.text_field :email %> <%= f.label :password %> <%= f.password_field :password %> <%= f.label :password_confirmation %> <%= f.password_field :password_confirmation %> <br> <% if current_page?(signup_path) %> <%= f.submit "Sign Up", class: "btn btn-large btn-primary" %> Or, <%= link_to "Login", login_path %> <% else %> <%= f.submit "Update User", class: "btn btn-large btn-primary" %> <% end %> <% end %> Users Controller: class UsersController < ApplicationController def index @user = User.all end def new @user = User.new end def create @user = User.create(params[:user]) if @user.save session[:user_id] = @user.id #once user account has been created, a session is not automatically created.

  • Rails redirections with new users and logins

    - by Kenji Crosland
    So I'm trying to get the user to return to the page they were looking at before they click "log in" This is what I got in my user application controller: def redirect_back_or_default(default) redirect_to(session[:return_to] || default) session[:return_to] = nil end And this is what I have in my sessions controller: def new @user_session = UserSession.new session[:return_to] = request.referer end end def create @user_session = UserSession.new(params[:user_session]) if @user_session.save flash[:notice] = "Login successful!" redirect_back_or_default(home_path) else render :action => :new end end This works fine most of the time but if a user logs in right after they register to the site, they will get redirected to a blank page. I imagine this is the "create" action because it was the last action before going to user sessions new. So I tried this: def new @user_session = UserSession.new unless request.referer == join_path session[:return_to] = request.referer end end And this tries to take me back to the login page after I log in. What I'd really like to do is have the user see their profile when they log in for the very first time. This wouldn't give me a user id and raised a routing error def create @user_session = UserSession.new(params[:user_session]) if @user_session.save flash[:notice] = "Login successful!" redirect_back_or_default(user_path(current_user)) else render :action => :new end end Anybody gone through these redirecting acrobatics before? I can't seem to get it to work. I'm using authlogic if that helps.

  • Rails Habtm with a field

    - by moshimoshi
    Hello, Is that possible to have a field in a has and belongs to many table? Just like favorite: create_table :messages_users, :id => false, :force => true do |t| t.integer :message_id, :null => false t.integer :user_id, :null => false t.boolean :favorite, :null => false t.timestamps end I saw timestamps works well, thanks to ActiveRecord. But when I try to add favorite into the table and then I try: Message.first.users << User.first Then I get this error message: ActiveRecord::StatementInvalid: SQLite3::SQLException: messages_users.favorite may not be NULL: INSERT INTO "messages_users" ("created_at", "message_id", "updated_at", "user_id") VALUES ('''2010-05-27 06:07 :50.721512''', 1, '''2010-05-27 06:07:50.721512''', 1) I would like to use a habtm, I don't like has_many foo though bar association :) Is that possible? Thanks a lot.

  • Can I retrieve objects from a complex query that limits results to fields from a single table?

    - by Sean Redmond
    I have a model whose rows I always want to sort based on the values in another associated model and I was thinking that the way to implement this would be to use set_dataset in the model. This is causing query results to be returned as hashes rather than objects, though, so none of the methods from the class can be used when iterating over the dataset. I basically have two classes class SortFields < Sequel::Model(:sort_fields) set_primary_key :objectid end class Items < Sequel::Model(:items) set_primary_key :objectid one_to_one :sort_fields, :class => SortFields, :key => :objectid end Some backstory: the data is imported from a legacy system into mysql. The values in sort_fields are calculated from multiple other associated tables (some one-to-many, some many-to-many) according to some complicated rules. The likely solution will be to just add the values in sort_fields to items (I want to keep the imported data separate from the calculated data, but I don't have to). First, though, I just want to understand how far you can go with a dataset and still get objects rather than hashes. If I set the dataset to sort on a field in items like so class Items < Sequel::Model(:items) set_primary_key :objectid one_to_one :sort_fields, :class => SortFields, :key => :objectid set_dataset(order(:sortnumber)) end then the expected clause is added to the generated SQL, e.g.: >> Items.limit(1).sql => "SELECT * FROM `items` ORDER BY `sortnumber` LIMIT 1" and queries still return objects: >> Items.limit(1).first.class => Items If I order it by the associated fields though... class Items < Sequel::Model(:items) set_primary_key :objectid one_to_one :sort_fields, :class => SortFields, :key => :objectid set_dataset( eager_graph(:sort_fields). order(:sort1, :sort2, :sort3) ) end ...I get hashes ?> Items.limit(1).first.class => Hash My first thought was that this happens because all fields from sort_fields are included in the results and maybe if selected only the fields from items I would get Items objects again: class Items < Sequel::Model(:items) set_primary_key :objectid one_to_one :sort_fields, :class => SortFields, :key => :objectid set_dataset( eager_graph(:sort_fields). select(:items.*). order(:sort1, :sort2, :sort3) ) end The generated SQL is what I would expect: >> Items.limit(1).sql => "SELECT `items`.* FROM `items` LEFT OUTER JOIN `sort_fields` ON (`sort_fields`.`objectid` = `items`.`objectid`) ORDER BY `sort1`, `sort2`, `sort3` LIMIT 1" It returns the same rows as the set_dataset(order(:sortnumber)) version but it still doesn't work: >> Items.limit(1).first.class => Hash Before I add the sort fields to the items table so that they can all live happily in the same model, is there a way to tell Sequel to return on object when it wants to return a hash?

  • Rails 3 : Can't get form_for to work as a 'delete' following the RESTful achitecture => always giving a ROUTING ERROR

  • One way Has-Many-Through

    - by Hock
    Hello, I have a Category, a Subcategory and a Product model. I have: Category has_many Subcategories Subcategory has_many Products Subcategory belongs_to Category Product belongs_to Subcategory Is there a way to have something like Category has_many Projects through Subcategories ? The 'normal' rails way wouldn't work because "subcategory" doesn't belongs to product so product does not have a subcategory_id field. Instead, I need the query to be something like SELECT * FROM products WHERE id IN category.subcategory_ids Is there a way to do that? Thanks, Nicolás Hock Isaza

  • Rails: Getting rid of generic "X is invalid" validation errors

    - by DJTripleThreat
    I have a sign-up form that has nested associations/attributes whatever you want to call them. My Hierarchy is this: class User < ActiveRecord::Base acts_as_authentic belongs_to :user_role, :polymorphic => true end class Customer < ActiveRecord::Base has_one :user, :as => :user_role, :dependent => :destroy accepts_nested_attributes_for :user, :allow_destroy => true validates_associated :user end class Employee < ActiveRecord::Base has_one :user, :as => :user_role, :dependent => :destroy accepts_nested_attributes_for :user, :allow_destroy => true validates_associated :user end I have some validation stuff in these classes as well. My problem is that if I try to create and Customer (or Employee etc) with a blank form I get all of the validation errors I should get plus some Generic ones like "User is invalid" and "Customer is invalid" If I iterate through the errors I get something like: user.login can't be blank User is invalid customer.whatever is blah blah blah...etc customer.some_other_error etc etc Since there is at least one invalid field in the nested User model, an extra "X is invalid" message is added to the list of errors. This gets confusing to my client and so I'm wondering if there is a quick way to do this instead of having to filer through the errors myself.
