  • How to get the "#" symbol in the :id into the redirect_to method in Rails

    - by Matthias Günther
    Hello, this is a silly questions but I don't understand, why rails isn't evaluating my string as expected. Here is my problem: I want to redirect to an url in the form ~/:controller/index/#_76 redirect_to :action => "index", :id => '#_76' But I'm getting the url in the form: ~/:controller/index/%25_76 and so my anchor for linking to a certain place in the website isn't working. Can someone please explain me, why rails makes this rendering? I think this hase something to do with url encoding. Again thanks for your help, I'm learning every day a little bit more about rails :).

  • Not delete params in URL, when sorting [ RAILS 3 ]

    - by kamil
    I have sortable table columns, made like that http://asciicasts.com/episodes/228-sortable-table-columns And I have simply filter options for two columns in table, made at select_tag (GET method). This two function don't work together. When I change filter, the sort parameter disappear and inversely. <th><%= sortable "Id" %></th> <th> Status<br/> <form method="get"> <%= select_tag(:status, options_for_select([['All', 'all']]+@statuses, params[:status]),{:onchange => 'this.form.submit()'}) %> </th> <th><%= sortable "Operation" %></th> <th> Processor<br/> <%= select_tag(:processor, options_for_select([['All', 'all']]+@processor_names, params[:processor]),{:onchange => 'this.form.submit()'}) %> </form> </th>

  • How to use gems not in a Gemfile when working with bundler?

    - by arikfr
    When using bundler with a project in general and Rails specifically, you have access only to gems defined in your Gemfile. While this makes sense, it can be limiting. Mostly I find it limiting when I want to use a certain RSpec formatter that the rest of the team doesn't use. Unless it's in the Gemfile, it isn't accessible. Any way around it or I have to add it to Gemfile? Update: my problem wasn't Bundler but Spork. When running RSpec without Spork I had no problem of using whatever formatter I wanted.

  • How to use string interpolation when rendering templates?

    - by Senthil
    I found this code in a Rails cookbook. class BlogController < ApplicationController def display_by_date year = params[:year] month = params[:month] day = params[:day] day ='0'+day if day && day.size == 1 @day = day if ( year && month && day ) render(:template => "blog/#{year}/#{month}/#{day}") elsif ( year ) render(:template => "blog/#{year}/list") end end end I'm not sure what to name the templates so the router can find them. Thanks for your help.

  • Rails precision error

    - by dontangg
    When I run this in my Rails application: my_envelope.transactions.sum(:amount) This SQL is shown in the log files: SQL (0.3ms) SELECT SUM("transactions"."amount") AS sum_id FROM "transactions" WHERE (envelope_id = 834498537) And this value is returned: <BigDecimal:1011be570,'0.2515999999 9999997E2',27(27)> As you can see, the value is 25.159999. It should be 25.16. When I run the same SQL on the database myself, the correct value is returned. I'm a little confused because I know that there are precision problems with Floats, but it is returning a BigDecimal. The SQL column type is decimal. Any ideas?

  • has_one update problem

    - by Kalyan M
    I have two models, User and Account. Each user may have one account. Creating an account for a user works fine. My problem is that when I try to update the account, the previous accounts user_id is nullified and a new account row is created with the user_id. I do not want this happening. I want to update the existing row with the changes to account. How do I do this? Thanks.

  • Form is creating already loaded attributes in addition to new attributes, how do I ignore the first?

    - by looloobs
    In my application you: Have an admin user that signs on and that user has a role (separate model), then I use the declarative_authorization plugin to give access to certain areas. That admin user can also register new users in the system, when they do this (using Authlogic) they fill out a nested form that includes that new users' role. So what is happening is the role of the admin user is being loaded by the declarative_authorization and then the nested form using the has_many_nested_attributes is loading that existing role as well as the new role for the new user (users can have many roles). Is there some way I can tell the new User being created to ignore the role assigned to the current_user and only create the role in the form for the new user? I have looked through a lot of different things, but it seems to get more complicated that these are nested attributes. Thanks in advance.

  • Does it make sense to use BOTH mongodb and mysql in the same rails application?

    - by Brian Armstrong
    I have a good reason to use mongodb for part of my app. But people generally describe it as not a good fit for "transactional" applications like a bank where transactions have to be exact/consistent, etc. Does it make sense to split the models up in Rails and have some of them use MySql and others mongo? Or will this generally cause more problems than it's worth? I'm not building a banking app or anything, but was thinking it might make sense for my users table or or transactions table (recording revenue) to do that part in MySql.

  • Rails 3 Join Question for Votes Table

    - by Dex
    I have a table posts and a polymorphic table votes. The votes table looks like this: create_table :votes do |t| t.references :user # user_id t.vote # the vote value t.references :votable # votable_type and votable_id end I want to list all posts that the user has not yet voted on. Right now I'm basically taking all the posts they've already voted on and subtracting that from the entire set of posts. It works but it's not very convenient as I currently have it. def self.where_not_voted_on_by(user) sql = "SELECT P.* FROM posts P LEFT OUTER JOIN (" sql << where_voted_on_by(user).to_sql sql << ") ALREADY_VOTED_FOR ON P.id = ALREADY_VOTED_FOR.id WHERE (user_id is null)" puts sql resultset = connection.select_all(sql) results = [] resultset.each do |r| results << Post.new(r) end results end def self.where_voted_on_by(user) joins(:votes.outer).where("user_id = #{user.id}").select("posts.*, votes.user_id") end

I have a search tag that looks for Model.find(:all, :conditions => "name LIKE params[search]") but I'd like for the search to find all records where "name LIKE params[search] or description LIKE params[search] . Is there any way to add an OR into a condition in rails? or should I make an if statement?

  • how to model a many to many relationship

    - by Maulin
    Here is the scenario, Articles have many Comments Users can write many Comments for many Articles The comments table contains both user_id article_id as foreign keys My models are set up like so class User < ActiveRecord::Base has_many :comments has_many :articles, :through => :comments class Article < ActiveRecord::Base has_many :comments has_many :users, :through => :comments class Comment < ActiveRecord::Base belongs_to :users belongs_to :articles My routes.rb has the following code map.resources :articles, :has_many => :comments map.resources :users, :has_many => :comments which produces the following routes new_article_comment edit_article_comment new_user_comment edit_user_comment etc... This is not what I want (atleast not what I think I want), since comments must always be related to users and article, how can I get a route like so new_user_article_comment edit_user_article_comment Then I could just do new_user_article_comment_path([@user, @article]) to create a new comment

  • Rails caches_page :index in Wrong Location

    - by Andy
    I have a controller Projects in my Rails app with: caches_page :index However, instead of the cached file being generated at /public/projects/index.html it is located at /public/projects.html. The web server (currently Mongrel) looks for */ directories before *.html files. So the http://…/projects request is routed through Rails and my index cache file is never served. How can I tell caches_page :index to generate the file at /public/projects/index.html instead?

  • Is it possible to send an automated email with dynamic content in Rails

    - by Danny McClelland
    Hi Everyone, I am looking into the best way of doing the following: I have a model called Kase, and when a user creates a new case then are taken to the show view as you would expect. I am trying to work out what the best way of sending an automated email between those two events is. I would need to include in the email the content of a couple of the fields, ideally I am looking for a way of just typing out the email and adding the same snippets that are in the show view for each of the fields I need. I am using the Base App from Github so the email sending is already setup for the user authentication and registration, but I'm not sure where to begin. The reason I want to send the email is to create a new Case in our Highrise account, and I don't have a clue how to use the API. So I think the email sending is the easier way. Thanks, Danny
