  • Rails - how to serialize a tree not in a form

    - by tiny_clanger
    I started with the standard scriptaculous drag and drop tree, and that all works fine. Then started implementing this: http://www.artweb-design.de/2008/5/30/scriptaculous-sortabletree which gives a good drag and drop tree Where I am stuck is how to get serialize the tree (unordered list)? It's not in a form, and I can't find a way to serialize it to move onto setting up the AJAX update.

  • How can I make three partials into just one in rails where the :collection is the same?

    - by Angela
    I have three partials that I'd like to consolidate into one. They share the same collection, but each gets passed its own :local variable. Those variables are used for specific Models, so as a result, I have three different calls to the partial and three different partials. Here's the repetitive code: <% for email in campaign.emails %> <h4><%= link_to email.title, email %> <%= email.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%> <!--contacts collection--> <!-- render the information for each contact --> <%= render :partial => "contact_email", :collection => @contacts, :locals => {:email => email} %> <% end %> Calls in this Campaign: <% for call in campaign.calls %> <h4><%= link_to call.title, call %> <%= call.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%> <!--contacts collection--> <!-- render the information for each contact --> <%= render :partial => "contact_call", :collection => @contacts, :locals => {:call => call} %> <% end %> Letters in this Campaign: <% for letter in campaign.letters %> <h4><%= link_to letter.title, letter %> <%= letter.days %> days</h4> <% @contacts= campaign.contacts.find(:all, :order => "date_entered ASC" )%> <!--contacts collection--> <!-- render the information for each contact --> <%= render :partial => "contact_letter", :collection => @contacts, :locals => {:letter => letter} %> <% end %> An example of one of the partials is as follows: < div id="contact_email_partial"> <% if from_today(contact_email, email.days) < 0 %> <% if show_status(contact_email, email) == 'no status'%> <p> <%= full_name(contact_email) %> <% unless contact_email.statuses.empty?%> (<%= contact_email.statuses.find(:last).status%>) <% end %> is <%= from_today(contact_email,email.days).abs%> days overdue: <%= do_event(contact_email, email) %> <%= link_to_remote "Skip Email Remote", :url => skip_contact_email_url(contact_email,email), :update => "update-area-#{contact_email.id}-#{email.id}" %> <span id='update-area-<%="#{contact_email.id}-#{email.id}"%>'> </span> <% end %> <% end %> </div>

  • Multi-model form problem

    - by raphael_turtle
    (I'm just learning rails so....) I have a photo model and a gallery model, habtm associations and a join table. I'm making a photo gallery. The gallery page has a title field and description field. User creates gallery title, then goes to the photo page and checkboxes each image they want in that gallery. I get the error "undefined method `to_i' for ["1", {"title"="1"}]:Array" when trying to save/update a photo with a gallery title(with the checkbox) <% form_for @photo, :html => {:multipart => true } do |f| %> <%= f.error_messages %> <p> <%= f.label :title %> <%= f.text_field :title %> </p> <p> <%= f.label :description %> <%= f.text_area :description %> </p> <p> <%= f.label :image %> <%= f.file_field :image %> </p> <% for gallery in @photo.galleries %> <% fields_for "painting[gallery_attributes][]", gallery do |g| %> <div> <%= g.check_box :title %> <%= gallery.title %> </div> <% end %> <% end %> <p><%= submit_tag 'Update' %></p> <% end %> How much of this is horribly wrong? Can someone point me in the right direction?, I can't find any tutorials relating to this for 2.3 and above.

  • Rails - set POST request limit (file upload)

    - by Fabiano PS
    I am building a file uploader for Rails, using CarrierWave. I am pretty happy about it's API, except that I don't seem to be able to cut file uploads that exceed a limit on the fly. I found this plugin for validation, but the problem is that it happens after the upload is completed. It is completely unacceptable in my case, as any user could take the site down by uploading a huge file. So, I figure that the way would be to use some Rack configuration or middleware that will limit POST body size as it receives. I am hosting on Heroku, as context. *I am aware of https://github.com/dwilkie/carrierwave_direct but it doesn't solve my issue as I have to resize first and discard the original large image.

  • counter_cache not updating on the model after save

    - by sehnsucht
    I am using a counter_cache to let MySQL do some of the bookkeeping for me: class Container has_many :items end class Item belongs_to :container, :counter_cache => true end Now, if I do this: container = Container.find(57) item = Item.new item.container = container item.save in the SQL log there will be an INSERT followed by something like: UPDATE `containers` SET `items_count` = COALESCE(`items_count`, 0) + 1 WHERE `containers`.`id` = 57 which is what I expected it to do. However, the container[:items_count] will be stale! ...unless I container.reload to pick up the updated value. Which in my mind sort of defeats part of the purpose of using the :counter_cache in favor of a custom built one, especially since I may not actually want a reload before I try to access the items_count attribute. (My models are pretty code-heavy because of the nature of the domain logic, so I sometimes have to save and create multiple things in one controller call.) I understand I can tinker with callbacks myself but this seems to me a fairly basic expectation of the simple feature. Again, if I have to write additional code to make it fully work, it might as well be easier to implement a custom counter. What am I doing/assuming wrong?

  • Why does false invalidate validates_presence_of?

    - by DJTripleThreat
    Ok steps to reproduce this: prompt> rails test_app prompt> cd test_app prompt> script/generate model event_service published:boolean then go into the migration and add not null and default published to false: class CreateEventServices < ActiveRecord::Migration def self.up create_table :event_services do |t| t.boolean :published, :null => false, :default => false t.timestamps end end def self.down drop_table :event_services end end now migrate your changes and run your tests: prompt>rake db:migrate prompt>rake You should get no errors at this time. Now edit the model so that you validate_presence_of published: class EventService < ActiveRecord::Base validates_presence_of :published end Now edit the unit test event_service_test.rb: require 'test_helper' class EventServiceTest < ActiveSupport::TestCase test "the truth" do e = EventServer.new e.published = false assert e.valid? end end and run rake: prompt>rake You will get an error in the test. Now set e.published to true and rerun the test. IT WORKS! I think this probably has something to do with the field being boolean but I can't figure it out. Is this a bug in rails? or am I doing something wrong?

  • Is there a way to have three way habtm associations in rails / activerecord?

    - by txwikinger
    Often three (or more) way associations are needed for habtm associations. For instance a permission model with roles. A particular area of functionality has many users which can access many areas. The permissions on the area are setup via roles (habtm) The user/roles association is also habtm The permissions (read, write, delete, etc) are habtm towards roles. How would that be best done with rails/activerecord?

  • How to disable Rails submit buttons alongside Prototype helpers & RJS?

    - by Jesse
    I'm trying to follow this post http://stackoverflow.com/questions/576240/how-can-i-unobtrusively-disable-submit-buttons-with-javascript-and-prototype but I can't get it to work. The form triggers an RJS function, so I need to keep the helpers' onclick events intact. The RJS returns/reloads the same forms along with two new texts. I'm really confused. Here is my rails code for the forms: .span-20#comparison / new comparison . . . / voting forms (also reloaded) .span-4.prepend-3.append-6 - form_remote_tag :action => url_for(:controller => :comparisons), :method => :post do = hidden_field_tag :poem1_id, poems[:a].id = hidden_field_tag :poem2_id, poems[:b].id = hidden_field_tag :response, 1 = submit_tag "Vote for me", :disabled => false, :disable_with => 'Vote for me', :class => "compare" .span-4.append-3.last - form_remote_tag :action => url_for(:controller => :comparisons), :method => :post do = hidden_field_tag :poem1_id, poems[:a].id = hidden_field_tag :poem2_id, poems[:b].id = hidden_field_tag :response, 2 = submit_tag "Vote for me", :disable_with => 'Vote for me', :class => "compare" .span-4.prepend-8.append-8.prepend-top.last - form_remote_tag :action => url_for(:controller => :comparisons), :method => :post do = hidden_field_tag :poem1_id, poems[:a].id = hidden_field_tag :poem2_id, poems[:b].id = hidden_field_tag :response, 'draw' = submit_tag "Declare Draw", :disable_with => 'Declare Draw', :class => "compare" RJS page.replace_html :comparison, :partial => 'poems', :object => @poems page.insert_html :top, :previous, :partial => 'comparison', :object => @comparison page << "Effect.ScrollTo($('top'));"

  • Is there a way to automatically grab all the elements on the page using Selenium?

    - by VGambit
    When creating tests for .Net applications, I can use the White library to find all elements of a given type. I can then write these elements to an Xml file, so they can be referenced and used for GUI tests. This is much faster than manually recording each individual element's info, so I would like to do the same for web applications using Selenium. I haven't been able to find any info on this yet. I would like to be able to search for every element of a given type and save its information (location/XPath, value, and label) so I can write it to a text file later.

  • How to factorize common tags with nokogiri builder ?

    - by plafoucriere
    Hi, I'd like to create several builders, with common tags, in order to have xml docs like : <xml version="1.0"?> <a_kind_of_root> <!-- This part is common --> <event_date>20100514</event_date> <event_id>123</event_id> <event_type>Conference</event_type> <!-- This part is specific to the builder --> <my_tag>some text</my_tag> </a_kind_of_root> </xml> <xml version="1.0"?> <another_kind_of_root> <!-- This part is common --> <event_date>20100514</event_date> <event_id>123</event_id> <event_type>Conference</event_type> <!-- This part is specific to the builder --> <my_other_tag>some integer</my_other_tag> </another_kind_of_root> </xml> I don't know how to put the common part inside a Nokogiri::XML::Builder Thanks

  • Expanding a row in a div-based table

    - by magneticMonster
    I have a stack of <div> elements that show a name. I'd like to include a + link off to the side that, when clicked, expands the <div> and adds more detailed information (from a RoR controller). After poking around on the net, I found link_to_remote and related RoR stuff, but I can't seem to get the right combination to work together. Can someone point me to a tutorial or show what the controller and view interaction should look like? Thanks!

  • Set a session hash outside of RoR program?

    - by Sindri Guðmundsson
    Hi, I have had my new rails program up for a few days now. I'm running it on Ubuntu 10.4 with apache2 in another location than the website it's made for (it's a standalone database application for physiotherapists). The people I made it for now want me to deploy it to the public part of their website, only with one change. Those who open it via the link in the public-part should not be able to click one button! I was thinking of doing something like this in my view: <% if session[:inside]%> <%=button_to 'Sækja mælitæki', @link_to_mt%> <%end%> How could I set session[:inside] only to true if the program was started from within the private part of the webpage? I thought of creating two new actions, the other would set session[:inside] to true and the other to false, but that seems to me like a security risk, is it not? BR, Sindri

  • Is it possible to set path of database for delayed job in rails?

    - by WitchOfCloud
    Now, I am developing with mailing system with delayed_jobs gem. When I ran on developing environment, it operated well. But, after deploying application on server, it is not acted. This is my database.yml development: adapter: sqlite3 database: db/development.sqlite3 pool: 5 timeout: 5000 test: adapter: sqlite3 database: db/test.sqlite3 pool: 5 timeout: 5000 production: adapter: sqlite3 database: /var/www/service/shared/db/production.sqlite3 pool: 5 timeout: 5000 I checked queue(in /var/www/...) and it act well. Also, I started delayed_jobs(rake jobs:work). So, I think that problem is delayed_job crawl db/development.sqlite3 How can solve this problem?

  • What to use to write tests? [Rails]

    - by yuval
    I asked a question about different testing frameworks yesterday. This question can be found here. Now that I have a better understanding of the different frameworks, I have a very simple question: With a basic understanding, but very limited experience with writing tests with rails' built in testing framework (basic assertions), would it be okay for me to jump directly to testing with RSpec, Webrat, and Cucamber? Thank you! As a side note: yes, this is an opinion based question, but I feel that the input received to this question is valuable enough to the community to keep this question open. Thanks.

  • Rails Form Submission, User can't be blank

  • Updating cached counts in MySQL

    - by phleet
    In order to fix a bug, I have to iterate over all the rows in a table, updating a cached count of children to what its real value should be. The structure of the things in the table form a tree. In rails, the following does what I want: Thing.all.each do |th| Thing.connection.update( " UPDATE #{Thing.quoted_table_name} SET children_count = #{th.children.count} WHERE id = #{th.id} " ) end Is there any way of doing this in a single MySQL query? Alternatively, is there any way of doing this in multiple queries, but in pure MySQL? I want something like UPDATE table_name SET children_count = ( SELECT COUNT(*) FROM table_name AS tbl WHERE tbl.parent_id = table_name.id ) except the above doesn't work (I understand why it doesn't).

  • MIgrations and Rspec

    - by pablorc
    Hi, I'm developing a Rails application with Rspec for unit testing. Weeks ago, Rspec used to migrate the database to the last version automatically when executing 'rake spec', but now it doesn't do it automatically, I have to implement everything for myself. This happens in test environment, because my development data doesn't desappear. Is my fault? I didn't change anything, I think :) Thanks in advance.
