  • Does anybody have any tips for managing polymorphic nested resources in Rails 3?

    - by Ryan
    in config/routes.rb: resources posts do resources comments end resources pictures do resources comments end I would like to allow for more things to be commented on as well. I'm currently using mongoid (mongomapper isn't as compatible with rails3 yet as I would like), and comments are an embedded resource (mongoid can't yet handle polymorphic relational resources), which means that I do need the parent resource in order to find the comment. Are there any elegant ways to handle some of the following problems: in my controller, I need to find the parent before finding the comment. if params[:post_id] parent = Post.find(params[:post_id] else if params[:picture_id] parent = Picture.find(params[:picture_id] end which is going to get messy if I start adding more things to be commentable also url_for([comment.parent,comment]) doesn't work, so I'm going to have to define something in my Comment model, but I think I'm also going to need to define an index route in the Comment model as well as potentially an edit and new route definition. There might be more issues that I have to deal with as I get further. I can't imagine I'm the first person to try and solve this problem, are there any solutions out there to make this more manageable?

  • thinking sphinx ordering by mixing capitals and lower case

    - by miccet
    I have a rails application that is using thinking_sphinx for the searching. My problem is that the result returned is sorted with capitals first and lower case after it at the bottom. I'd like to mix them so that both 'A' and 'a' comes before 'B'. This is the method I'm using: Company.search(query, :star => true, :page => params[:page], :per_page => 20, :order => :name, :sort_mode => :asc)

  • Rails3 Redirect for javascript/ajax

    - by Tiago
    Hi, I'm using a form with the remote => true. I have a validation that is working correctly. My problem is when the user enters all the correct information and writes the data at this time I do a redirect to the page of the show. Instead of redirecting, it displays the html of the show in my div. How can I make a javascript redirect that will understand? I did not want to use the window.location. Thanks...

  • Conditional root_url (index)

    - by vise
    I'd like my application to display different data on the frontpage depending on whether the user has been logged in or not. def index if current_user # render another controllers action else # render another controllers action end end I can achieve this by using render_component. However it has been obsolete for some time. Although I can still use it as a plugin, I'm interested if anyone has a better approach. Just take in mind that rendering another controller's view directly is not an option. Thanks.

  • Showing pagination with only single page using will_paginate

    - by James
    I'm using will_paginate as standard, but it only shows the pagination controls (< 1 2 etc) when there's more than one page to display. Normally, this would be what is wanted, but I want to see the pagination controls (for UI consistency and to get round an annoying CSS quirk in the system I'm working on) even when there's only 1 page to display (showing < 1 ). Is this possible?

  • Searching in Rails 3

    - by cbarton
    Here is the situation: I have the need to search for specifics or generals, much like expedia.com or your local library catalog search. In that there are fields that may or may not be filled out based on the individual need. It acts much like an "advanced search page". I have all of that code done for the models/controller and such and have it setup with a Searches controller along with matching model and views. The question that I have is there a way to cut down the amount of parameters posted to GET so that the url isn't search?search[:a]=""+search[:b]=""+search[:c]="x"... plus the unicode checkmark. I only want the filled out fields to be shown in the response link especially minus the checkmark. cbarton

  • rake tast can't access rails.cache

    - by mark
    Hi I want to call a rake task from a cron job that stores remote weather data in the rails cache. However, I must be doing something pretty wrong here because I cannot find any solution through countless fruitless searches. Say I define and call this task namespace :weather do desc "Store weather from remote source to cache" task :cache do Rails.cache.write('weather_data', Date.today) end end I get the error Anonymous modules have no name to be referenced by Which leads me to believe the rails cache isn't available. Outputting Rails.class from the rake file gives me Module but Rails.cache.class again returns the above error. Do I need to include something here? Am I just hopeless at internet? :) Thanks in advance.

  • Rails routes looking for show action

    - by user1334345
    I am pretty new to rails and basically I want to make a user registration form. I am currently using rails 3.2.3 Basically I want to make basic routes like user/register on top of basic REST route for user. Here are my routes.rb resources :user do collection do get 'register' end end And here are my rake routes: register_user_index GET /user/register(.:format) user#register user_index GET /user(.:format) user#index POST /user(.:format) user#create new_user GET /user/new(.:format) user#new edit_user GET /user/:id/edit(.:format) user#edit user GET /user/:id(.:format) user#show PUT /user/:id(.:format) user#update DELETE /user/:id(.:format) user#destroy From my understanding, since register user is on top of show, it should match with register first before going to show. However, when I try to do localhost:3000/user/register, it gives me this error: No route matches {:action="show", :controller="user"} Can somebody help me with this? Thanks!!

  • Take data from an XML file and put it into a MySQL database

    - by Aidan
    Hi Guys, I'm looking to construct a script that would go through an XML file. Would find specific tags in it, put them in a table and fill the table with specific tags within them. I'm using MySQL 5.1 so loadXML isn't an option and I think that ExtractData() method wont be much use either.. but I don't really know. What would be the best way to go about this?

  • How can I get all the checked items from a submitted form with sinatra's params?

    - by 102405176597896213397
    I'm running Sinatra 1.0 with HAML, my form has a number of checkboxes, for example books I like, and you would select all the books you want. The checkbox name is "books". In sinatra params['books'] there should be an array of all the books that were checked, but it only has the last item that was checked, not an array. How can I get all the checked items? HAML: %form{:action => "/test", :method => 'post'} %input{:name=>'check',:type=>'checkbox',:value=>'item1'} item 1 %input{:name=>'check',:type=>'checkbox',:value=>'item2'} item 2 %input{:name=>'check',:type=>'checkbox',:value=>'item3'} item 3 %input{:type => "submit", :value => "send", :class => "button"} Sinatra get method post '/test' do puts params['check'] #should be an array but is last item checked end

  • How to scale thumbnail to fit depending on tall or wide photo - Attachment_fu

    - by adamwstl
    I'm using attachment_fu and Rmagick to create thumbnails after upload. The thumbnail is a fixed 135 x 135 px and I'm currently forcing the width to 135px on all photos. The problem is that if it's a wide and fat photo is has to stretch the height awkwardly. Current Attachment_fu setup class PhotoImage < Image belongs_to :photo has_attachment :content_type => :image, :size => 0..5.megabytes, :storage => :s3, :resize_to => '650x>', :thumbnails => { :thumbnail => '135x>' }#:geometry => 'x50' } validates_as_attachment end Here's what I'm trying to do: Thanks

  • Can an ActiveRecord before_save filter halt the save without halting the transaction?

    - by Michael Boutros
    Is there any way for a before_save filter to halt the entire save without halting the transaction? What I'm trying to do is have a "sample" version of my model that the user can interact with and save but the changes themselves are never actually saved. The following will halt the transaction and (naturally) return false when I call @model.update_attributes: before_filter :ignore_changes_if_sample def ignore_changes_if_sample if self.sample? return false end end Thanks!

  • Where do I put the Current user query so as to not repeat per controller?

    - by Kevin
    I have a standard query that gets the current user object: @user = User.find_by_email(session[:email]) but I'm putting it as the first line in every single controller action which is obviously not the best way to do this. What is the best way to refactor this? Do I put this as a method in the Application controller (and if so, can you just show me a quick example)? Do I put the entire @user object into the session (has about 50 columns and some sensitive ones like is_admin)? Or is there another way to remove this kind of redundancy?

  • Rails object inheritence with belongs_to

    - by Rabbott
    I have a simple has_many/belongs_to relationship between Report and Chart. The issue I'm having is that my Chart model is a parent that has children. So in my Report model I have class Report < ActiveRecord::Base has_many :charts end And my Chart model is a parent, where Pie, Line, Bar all inherit from Chart. I'm not sure where the belongs_to :report belongs within the chart model, or children of chart model. I get errors when I attempt to access chart.report because the object is of type "Class" undefined local variable or method `report' for #< Class:0x104974b90 The Chart model uses STI so its pulling say.. 'Pie' from the chart_type column in the charts table.. what am I missing?

  • Can using Chronic impair you sense of time?

    - by Trip
    Haha.. I'm using Chronic to parse the time users add in the Calendar. Where the code works and implements the right time, the end result is that, IF a user adds a time, then it has no date, and because it has no date, it will not show in results. Any ideas? def set_dates unless self.natural_date.blank? || Chronic.parse(self.natural_date).blank? # check if we are dealing with a date or a date + time if time_provided?(self.natural_date) self.date = nil self.time = Chronic.parse(self.natural_date) else self.date = Chronic.parse(self.natural_date).to_date self.time = nil end end unless self.natural_end_date.blank? || Chronic.parse(self.natural_end_date).blank? # check if we are dealing with a date or a date + time if time_provided?(self.natural_end_date) self.end_date = nil self.end_time = Chronic.parse(self.natural_end_date) else self.end_date = Chronic.parse(self.natural_end_date).to_date self.end_time = nil end end end

  • Rails Testing Question

    - by Steve
    Hi, I am trying to test a functionality, which inserts few details into the DB. In the test.log, it shows the insert command that is generated and also the log messages that I have placed to show the progress and everything seems to be working fine except the actual data is not getting inserted into the DB. I am checking whether data is inserted in db/test.sqlite3. No exception is generated when the test cases are run. Is there a setting, which I have to set inorder to insert data into the test DB? or am i missing anything else Thanks

  • Capistrano deploy:migrate Could not find rake-0.9.2.2 in any of the sources

    - by Kyle
    My Capistrano deploy:migrate task is set to run a simple rake db:migrate command, as follows: env PATH=/home/user/.gems/bin sh -c 'cd /home/user/app/releases/20121003140503 && rake RAILS_ENV=production db:migrate' When I run this task during an ssh session manually it completes successfully. However when I run from my local development box, I receive the following error: ** [out :: app] Could not find rake-0.9.2.2 in any of the sources I am able to locate my rake gem by typing which rake via ssh (/home/user/.gems/bin/rake) and rake --version gives me "rake, version 0.9.2.2," so I don't understand why this command fails via Capistrano?
