  • Next, Previous Records Using Named Scope

    - by keruilin
    I have a model for which I want to retrieve the next record(s) and previous record(s). I want to do this via a named_scope on the model, and also pass in as an argument the X number of next/previous records to return. For example, let's say I have 5 records: Record1 Record2 Record3 Record4 Record5 I want to be able to call Model.previous or Model.previous(1) to return Record2. Similarly, I want to be able to call Model.next or Model.next(1) to return Record4. As another example I want to be able to call Model.previous(2) to return Record3. I think you get the idea. How can I accomplish this?

  • How to I get rid of these double quotes?

    - by Danger Angell
    I'm using ym4r to render a Google Map. Relevant portion of Controller code: @event.checkpoints.each do |checkpoint| unless checkpoint.lat.blank? current_checkpoint = GMarker.new([checkpoint.lat, checkpoint.long], :title => checkpoint.name, :info_window => checkpoint.name, :icon => checkpoint.discipline.icon, :draggable => false ) @map.overlay_init(current_checkpoint) end It's this line that is hanging me up: :icon => checkpoint.discipline.icon, Using this to render the map in the view: <%= @map.to_html %> <%= @map.div(:width => 735, :height => 450, :position => 'relative') %> The javascript that is puking looks like this: icon : "mtn_biking" and I need it looking like this: icon : mtn_biking This is the HTML generated: <script type="text/javascript"> var mtn_bike = addOptionsToIcon(new GIcon(),{image : "/images/map/mtn_bike.png",iconSize : new GSize(32,32),iconAnchor : new GPoint(16,32),infoWindowAnchor : new GPoint(16,0)});var map; window.onload = addCodeToFunction(window.onload,function() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("map")); map.setCenter(new GLatLng(37.7,-97.3),4);map.addOverlay(addInfoWindowToMarker(new GMarker(new GLatLng(34.9,-82.22),{icon : "mtn_bike",draggable : false,title : "CP1"}),"CP1",{})); map.addOverlay(addInfoWindowToMarker(new GMarker(new GLatLng(35.9,-83.22),{icon : "flat_water",draggable : false,title : "CP2"}),"CP2",{})); map.addOverlay(addInfoWindowToMarker(new GMarker(new GLatLng(36.9,-84.22),{icon : "white_water",draggable : false,title : "CP3"}),"CP3",{}));map.addControl(new GLargeMapControl()); map.addControl(new GMapTypeControl()); } }); </script> the issue is the double quotes in: icon : "mtn_bike" icon : "flat_water" icon : "white_water" I need a way to get rid of those double quotes in the generated HTML

  • form_tag for search model

    - by kip
    I have a search controller which is to be used to search over a separate model called house. The house model has a restful setup. I want the results listed on the index action of the search controller. The form_tag url is giving me some problems. What is the correct path for this? Below is the search form (search/form): <% form_tag index_search do -%> <p> <%= collection_select(:house, :category_id, Category.all, :id, :name) %> </p> <p> <strong>price</strong><br /> <%= text_field_tag :min_price, params[:min_price], :size => 3 %> <%= text_field_tag :max_price, params[:max_price], :size => 4 %>

  • Why can't I set boolean columns with update?

    - by Benjamin Oakes
    I'm making a user administration page. For the system I'm creating, users need to be approved. Sometimes, there will be many users to approve, so I'd like to make that easy. I'm storing this as a boolean column called approved. I remembered the Edit Multiple Individually Railscast and thought it would be a great fit. However, I'm running into problems which I traced back to ActiveRecord::Base#update. update works fine in this example: >> User.all.map(&:username) => ["ben", "fred"] >> h = {"1"=>{'username'=>'benjamin'}, "2"=>{"username"=>'frederick'}} => {"1"=>{"username"=>"benjamin"}, "2"=>{"username"=>"frederick"}} >> User.update(h.keys, h.values) => ... >> User.all.map(&:username) => ["benjamin", "frederick"] But not this one: >> User.all.map(&:approved) => [true, nil] >> h = {"1"=>{'approved'=>'1'}, "2"=>{'approved'=>'1'}} >> User.update(h.keys, h.values) => ... >> User.all.map(&:approved) => [true, nil] Chaging from '1' to true didn't make a difference when I tested. What am I doing wrong?

  • How to connect to SQLServer 2k5 using Ruby 1.8.7 over W2k3 with active record 2.3.5

    - by Luke
    Hi all, sorry for the blast. I'm trying to connect to an SQLServer 2k5 using Ruby 1.8.7 over W2k3 with active record 2.3.5. But, when I ran 'rake migrate' it throws the following: rake migrate --trace Hoe.new {...} deprecated. Switch to Hoe.spec. Invoke migrate (first_time) Invoke environment (first_time) Execute environment Execute migrate rake aborted! no such file to load -- odbc (...) C:/Program Files/test/Rakefile:146 (...) So, my Rakefile in the line 146 says: ActiveRecord::Migrator.migrate('db/migrate', ENV["VERSION"] ? ENV["VERSION"].to_i : nil ) The database.yml has been configured in so many ways without success. I've tried setup to mode in odbc, to configure a system dsn, to completely use the activerecord support for sqlserver but no success at all. The same Rakefile works fine over Postgres and Oracle with the proper gems installed off course. But I cann't get this work. Any help will be appreciated. Thanks in advance!

  • Add querystring parameters to link_to

    - by Craig
    I'm having difficultly adding querystring parameters to link_to UrlHelper. I have an Index view, for example, that has UI elements for sorting, filtering, and pagination (via will_paginate). The will_paginate plugin manages the intra-page persistence of querystring parameters correctly. Is there an automatic mechanism to add the querystring parameters to a give named route, or do I need to do so manually? A great deal of research on this seemingly simple construct has left me clueless.

  • How do I create Twitter style URL's for my app - Using existing application or app redesign - Ruby o

    - by bgadoci
    I have developed a blog application of sorts that I am trying to allow other users to take advantage of (for free and mostly for family). I wondering if the authentication I have set up will allow for such a thing. Here is the scenario. Currently the application allows for users to sign up for an account and when they do so they can create blog posts and organize those posts via tags. The application displays no data publicly (another words, you have to login to see anything). To gain access you have to create an account and even after you do, you cannot see anyone else's information as the applications filters using the current_user method and displays in the /posts/index.html.erb page. This would be great if a user only wanted to blog and share it with themselves, not really what I am looking for. My question has two parts (hopefully I won't make anyone mad by not putting these into two questions) Is it possible for a particular users data to live at www.myapplication.com/user without moving everything to the /user/show.html.erb file? Is it possible to make some of that information (living at the URL) public but still require login for create and destroy actions. Essentially, exactly like twitter. I am just curious if I can get from where I am (using the current_user methods across controllers to display in /posts/index.html.erb) to where I want to be. My fear is that I have to redesign the app such that the user data lives in the /user/show.html.erb page. Thoughts?

  • getting rid of ruby gems that won't die

    - by holden
    I've got a few ruby gems that won't go away. I think it has to do with when I installed them. Occasionally I have forgotten to use "sudo" before doing a gem install, which results in a write error and from what I can gather puts a copy of the gem in my user directory instead of somewhere it can run. But gem uninstall doesn't work. It continually shows up in 'gem list' but can't uninstall it from either gem uninstall, or sudo gem uninstall. I tried directly deleting one gem after finding the path in my 'gem environment', but that still left the gem on the list. Also is it possible just to remove all gems and start from scratch? These are driving me nuts. I'm running OS X. Thanks,

  • Searchlogic cannot sort search result

    - by jaycode
    Imagine a code: search = Project.search( :title_or_description_or_child_name_or_child_age_or_inspiration_or_decorating_style_or_favorite_item_or_others_like_any => keys, :galleries_id_like_any => @g, :styles_id_like_any => @st, :tags_like_any => @t ) search.all returns the rows correctly. But search.descend_by_views returns nil. Is this gem buggy? What else should I use then?

  • Remaking this loop by user?

    - by Elliot
    I'm wondering if theres a best practice for what I'm trying to accomplish... First we have the model categories, categories, has_many posts. Now lets say, users add posts. Now, I have a page, that I want to display only the current user's posts by category. Lets say we have the following categories: A, B, and C User 1, has posted in Categories A and B. In my view I have something like: <% @categories.select {|cat| cat.posts.count > 0}.each do |category| %> <%= category.name %><br/> <% category.posts.select {|post| post.user == current_user}.each do |post| %> <%= post.content %><br/> <% end %> <% end %> For the most part its almost there. The issue is, it will still show an empty category if any posts have been entered in it at all (even if the current user has not input posts into that category. So the question boils down to: How do I make the following loop only count posts in the category from the current user? <% @categories.select {|cat| cat.posts.count 0}.each do |category| % Best, Elliot

  • Web site aggregation with twitter widget SSL issue

    - by AB
    Hello! I'm seeking for solution how to isolate widget included by partial to main site. Issue appear when user access site with https. Ie 6,7 shows security confirmation dialog (part of website resources are not in secure zone). First of all I download twitter widget on our side, also I download all CSS and pictures. Then I patched widget JS to point onto downloaded resources. But still has not luck with security warning :( I guess the reason of this issue is AJAX request to twitter, but there is no idea how to sole it. (Just to create some kind of proxy on our side). Thank you for attention.

  • authlogic auto_register feature using my options

    - by holden
    I have auto registration working with authlogic using gaizka's version of authlogic_openid which I found on Github since pelle's original addition of the feature seemed to cause issues. http://github.com/gaizka/authlogic%5Fopenid http://stackoverflow.com/questions/1476953/using-authlogic-to-auto-create-users-bypassing-explicit-user-registeration This one works fine however when using the auto_register feature it ignores my options for authlogic such as retrieving the email from the openid provider... any ideas what I'm doing wrong? Hhere's the example: http://big-glow-mama.heroku.com/ http://github.com/holden/authlogic_openid_selector_example/tree/with-facebook/ You can see the difference if you register vs. login... #user.rb class User < ActiveRecord::Base acts_as_authentic do |c| c.validate_login_field = false # optional, but if a user registers by openid, he should at least share his email-address with the app c.validate_email_field = false # fetch email by ax c.openid_required_fields = [:email,"http://axschema.org/contact/email"] #c.required_fields = ["http://axschema.org/contact/email"] # fetch email by sreg #c.optional_fields = ["email"] end #private method to deal with emails goes here end #UserSession.rb class UserSession < Authlogic::Session::Base auto_register logout_on_timeout true end

How do I combine both of these lines of code and store the data in JSON format in the var adds variable? If you are interested in source, its here. The location is layout/adds.html.erb

The issue is, if neither have been created yet, they don't have ID's yet - so how can I assign linking values? Thanks! -Elliot

  • How do you pass variables to class_eval in ruby?

    - by klochner
    I'm working on a metaprogramming task, where I'm trying to use a single method to define a polymorphic association in the calling class, while also defining the association in the target class. I need to pass in the name of the calling class to get the association right. Here's a snippet that should get the idea across: class SomeClass < ActiveRecord::Base has_many :join_models, :dependent=:destroy end class JoinModel < ActiveRecord::Base belongs_to :some_class belongs_to :entity, :polymorphic=true end module Foo module ClassMethods def acts_as_entity has_many :join_models, :as=:entity, :dependent=:destroy has_many :some_classes, :through=:join_models klass = self.name.tableize SomeClass.class_eval "has_many :#{klass}, :through=:join_models" end end end I'd like to eliminate the klass= line, but don't know how else to pass a reference to self from the calling class into class_eval. any suggestions?
