• Tagging in rails with is_taggable

  - by poseid

  there is an example provided on how to add tags to a model with is_taggable, and it works very nice (working in 5 minutes) Now, I also need the opposite, show all records that are tagged with a certain word. Something like: ModelWithTag.find_by_tags "foo" or find_all_tagged_with "foo" Is this possible with is_taggable ?

• Rails: link_to_remote prototype helper with :with option

  - by Syed Aslam

  I am trying to grab the current value of a drop down list with Prototype and passing it along using :with like this <%= link_to_remote "today", :update => "choices", :url => { :action => "check_availability" } , :with => "'practitioner='+$F('practitioner')&'clinic='+$F('clinic')&'when=today'", :loading => "spinner.show(); $('submit').disable();", :complete => "spinner.hide(); $('submit').enable();" %> However, this is not working as expected. I am unable to access parameters in the controller as the link_to_remote helper is sending parameters like this: Parameters: {"succ"=>"function () {\n return this + 1;\n}", "action"=>"check_availability", "round"=>"function () {\n return __method.apply(null, [this].concat($A(arguments)));\n}", "ceil"=>"function () {\n return __method.apply(null, [this].concat($A(arguments)));\n}", "floor"=>"function () {\n return __method.apply(null, [this].concat($A(arguments)));\n}", "times"=>"function (iterator, context) {\n $R(0, this, true).each(iterator, context);\n return this;\n}", "toPaddedString"=>"function (length, radix) {\n var string = this.toString(radix || 10);\n return \"0\".times(length - string.length) + string;\n}", "toColorPart"=>"function () {\n return this.toPaddedString(2, 16);\n}", "abs"=>"function () {\n return __method.apply(null, [this].concat($A(arguments)));\n}", "controller"=>"main"} Where am I going wrong? Is there a better way to do this?

• Routing trouble for RESTful API - Rails

  - by aressidi

  I'm building out an API for web app that I've been working on for some time. I've started with the User model. The user portion of the API will allow remote clients to a) retrieve user data, b) update user information and c) create new users. I've gotten all of this to work, but it doesn't seem like its setup correctly. Here are my questions: Should the API endpoint be users or user? What's the best practice? I have to add the action to the end, which I would expect to be picked up instead by the request type so I don't have to specify it explicitly. How do I get my routes setup properly as not to have to include the method for protected actions? Let me give some examples: Get request for show - want it to work without the "show" curl -u rmbruno:blah http://app.local/api/users/show Put request for update - want it to work without the "update" curl -X put -F 'user[forum_notifications]=true' -u rmbruno:blah http://app.local/api/users/update Create - works with or without 'create' which is what I want for all these actions curl -X post -F 'user[login]=mamafatta' -F 'user[email][email protected]' -F 'user[password]=12345678' http://twye.local/api/users/ How do I structure routes to not require the action name? Isn't that the common way to to RESTful APIs? Here is my route for the API now: map.namespace :api do |route| route.resources :users route.resources :weight end I'm using restful authentication which is handling the http auth in curl. Any guidance on the routes issues and best practice on singular versus plural would be really helpful. Thanks! -A

• Rails migration for change column

  - by b_ayan

  We have script/generate migration add_fieldname_to_tablename fieldname:datatype syntax for adding new columns to a model. On the same line, do we have a script/generate for changing the datatype of a column? Or should I write sql directly into my vanilla migration? I want to change a column from datetime to date.

• Rails Heroku Migrate Unknown Error

  - by Ryan Max

  Hello. I am trying to get my app up and running on heroku. However once I go to migrate I get the following error: $ heroku rake db:migrate rake aborted! An error has occurred, this and all later migrations canceled: 530 5.7.0 Must issue a STARTTLS command first. bv42sm676794ibb.5 (See full trace by running task with --trace) (in /disk1/home/slugs/155328_f2d3c00_845e/mnt) == BortMigration: migrating ================================================= -- create_table(:sessions) -> 0.1366s -- add_index(:sessions, :session_id) -> 0.0759s -- add_index(:sessions, :updated_at) -> 0.0393s -- create_table(:open_id_authentication_associations, {:force=>true}) -> 0.0611s -- create_table(:open_id_authentication_nonces, {:force=>true}) -> 0.0298s -- create_table(:users) -> 0.0222s -- add_index(:users, :login, {:unique=>true}) -> 0.0068s -- create_table(:passwords) -> 0.0123s -- create_table(:roles) -> 0.0119s -- create_table(:roles_users, {:id=>false}) -> 0.0029s I'm not sure exactly what it means. Or really what it means at all. Could it have to do with my Bort installation? I did remove all the open-id stuff from it. But I never had any problems with my migrations locally. Additionally on Bort the Restful Authentication uses my gmail stmp to send confirmation emails...all the searches on google i do on STARTTLS have to do with stmp. Can someone point me in the right direction?

• Grouping search results with thinking_sphinx plugin for rails

  - by Shagymoe

  I can use the following to group results, but it only returns one result per group. @results = Model.search params[:search_query], :group_by => 'created_at', :group_function => :day, :page => params[:page], :per_page => 50 So, if I display the results by day, I only get one result per day. <% @results.each_with_groupby do |result, group| %> <div class="group"><%= group %></div> <ul class="result"> <li><%= result.name %></li> </ul> <% end %> Do I have to parse the @results array and group them by date manually or am I missing something? Here is the line from the sphinx docs: http://sphinxsearch.com/docs/current.html#clustering "The final search result set then contains one best match per group."

• Synchronize locale yml files tool in Rails

  - by Konstantinos

  I was wondering, is it possible to synchronize with any tool or gem or w/e 2 or more yml files? eg. i have the Greek yml file called el.yml el: layout: home: "??????" and the english one called en.yml en: layout: home: "Home" category: "Category" Is there any tool that based on a single yml file ie en.yml ( root ) that goes to the rest of the ymls and creates the missing translations with the default (en.yml) values? After running such a tool i would expect to have the el.yml become likes this: el: layout: home: "??????" category: "Category" I am using a similar tool in .NET RESX Synchronizer and it does exactly that, but for resx files.

• Rails activerecord attributes=

  - by vinhboy

  Hi, I am doing this: @person.attributes = params[:person] Can anyone give me a clue as to why doing an attributes= would cause a bunch of SQL to show in my logs? I see a couple of SELECT and even an UPDATE. I swear I am not doing a "save" -- so I have no idea why setting attributes would trigger queries. Is there a before_ of after_ filter I am missing? Thanks.

• rails ajax redirect

  - by badnaam

  Here is my use case I have a search model with two actions search_set and search_show. 1 - A user loads the home page which contains a search_form, rendered via a partial (search_form). 2 - User does a search, and the request goes to search_set, the search is saved and a redirect happens to search_show page which again renders the search_form with the saved search preferences. This search form is different than the one if step1, because it's a remote form being submitted to the same action (search set) 3 - Now the user does another search, and the search form is submitted via ajax to the search_set action. The search is saved and executed and now I need to present the result via rjs templates (corresponding to search_show). I am told that if the request is xhr then I can't redirect to the search_show action? Is that right? If yes, how do I handle this? Here is my controller class http://pastie.org/993460 Thanks

• Should I put my flex project within my rails project?

  - by ChrisInCambo

  I have a project with a RESTful Rails back-end and a Flex front-end, first time for me with this combo and I debating whether to put the flex source somewhere inside the Rails folder hierarchy or making it a separate project. If I do so which folder would be most suitable /lib? Also be doing one click deployment with Vlad which can also compile the flex app and dump it in the public folder. Or does anyone have any good reasons why the flex project shouldn't reside within the Rails folder hierarchy? Cheers

• Find items with belongs_to associations in Rails?

  - by dannymcc

  Hi Everyone, I have a model called Kase each "Case" is assigned to a contact person via the following code: class Kase < ActiveRecord::Base validates_presence_of :jobno has_many :notes, :order => "created_at DESC" belongs_to :company # foreign key: company_id belongs_to :person # foreign key in join table belongs_to :surveyor, :class_name => "Company", :foreign_key => "appointedsurveyor_id" belongs_to :surveyorperson, :class_name => "Person", :foreign_key => "surveyorperson_id" I was wondering if it is possible to list on the contacts page all of the kases that that person is associated with. I assume I need to use the find command within the Person model? Maybe something like the following? def index @kases = Person.Kase.find(:person_id) or am I completely misunderstanding everything again? Thanks, Danny EDIT: If I use: @kases= @person.kases I can successfully do the following: <% if @person.kases.empty? %> No Cases Found <% end %> <% if @person.kases %> This person has a case assigned to them <% end %> but how do I output the "jobref" field from the kase table for each record found?

• rails wiki site - article edit highlighting/strikethrough with htmldiff maxes cpu

  - by mark

  Hi I'm implementing a wiki style site and want to highlight changes made to articles between successive versions. Using htmldiff to highlight changes works great, except it is rather cpu intensive. I'm using the awesome vestal_versions plugin for versioning. So how best to handle this? I considered having an on_create callback on version creation create a delayed job that processes and then stores the htmldiff processed article (in the version table row). If this is a good approach, how can I extend vestal_versions without touching the gem? Or maybe there would be a better approach. Any advice is much appreciated. :)

• migrating from Prototype to jQuery in Rails, having trouble with duplicate get request

  - by aressidi

  I'm in the process of migrating from Prototype to jQuery and moving all JS outside of the view files. All is going fairly well with one exception. Here's what I'm trying to do, and the problem I'm having. I have a diary where users can update records in-line in the page like so: user clicks 'edit' link to edit an entry in the diary a get request is performed via jQuery and an edit form is displayed allowing the user to modify the record user updates the record, the form disappears and the updated record is shown in place of the form All of that works so far. The problem arises when: user updates a record user clicks 'edit' to update another record in this case, the edit form is shown twice! In firebug I get a status code 200 when the form shows, and then moments later, another edit form shows again with a status code of 304 I only want the form to show once, not twice. The form shows twice only after I update a record, otherwise everything works fine. Here's the code, any ideas? I think this might have to do with the fact that in food_item_update.js I call the editDiaryEntry() after a record is updated, but if I don't call that function and try and update the record after it's been modified, then it just spits up the .js.erb response on the screen. That's also why I have the editDiaryEntry() in the add_food.js.erb file. Any help would be greatly appreciated. diary.js jQuery(document).ready(function() { postFoodEntry(); editDiaryEntry(); initDatePicker(); }); function postFoodEntry() { jQuery('form#add_entry').submit(function(e) { e.preventDefault(); jQuery.post(this.action, jQuery(this).serialize(), null, "script"); // return this }); } function editDiaryEntry() { jQuery('.edit_link').click(function(e) { e.preventDefault(); // This should look to see if one version of this is open... if (jQuery('#edit_container_' + this.id).length == 0 ) { jQuery.get('/diary/entry/edit', {id: this.id}, null, "script"); } }); } function closeEdit () { jQuery('.close_edit').click(function(e) { e.preventDefault(); jQuery('.entry_edit_container').remove(); jQuery("#entry_" + this.id).show(); }); } function updateDiaryEntry() { jQuery('.edit_entry_form').submit(function(e) { e.preventDefault(); jQuery.post(this.action, $(this).serialize(), null, "script"); }); } function initDatePicker() { jQuery("#date, #edit_date").datepicker(); }; add_food.js.erb jQuery("#entry_alert").show(); jQuery('#add_entry')[ 0 ].reset(); jQuery('#diary_entries').html("<%= escape_javascript(render :partial => 'members/diary/diary_entries', :object => @diary, :locals => {:record_counter => 0, :date_header => 0, :edit_mode => @diary_edit}, :layout => false ) %>"); jQuery('#entry_alert').html("<%= escape_javascript(render :partial => 'members/diary/entry_alert', :locals => {:type => @type, :message => @alert_message}) %>"); jQuery('#entry_alert').show(); setTimeout(function() { jQuery('#entry_alert').fadeOut('slow'); }, 5000); editDiaryEntry(); food_item_edit.js.erb jQuery("#entry_<%= @entry.id %>").hide(); jQuery("#entry_<%= @entry.id %>").after("<%= escape_javascript(render :partial => 'members/diary/food_item_edit', :locals => {:user_food_profile => @entry}) %>"); closeEdit(); updateDiaryEntry(); initDatePicker(); food_item_update.js jQuery("#entry_<%= @entry.id %>").replaceWith("<%= escape_javascript(render :partial => 'members/diary/food_item', :locals => {:entry => @entry, :total_calories => 0}) %>"); jQuery('.entry_edit_container').remove(); editDiaryEntry();

• Rails 3 time output

  - by Oluf Nielsen

  Hi, I'm now working on my output of the feeds I'm taking in from some site. What I'm currently doing is Time, and i want it to be displayed in a maybe, little be special way.. like this.. today, 14:12 yesterday, 15:34 27/12, 15:24 i have this in my code = news.entry_published.strftime("%d/%m, %H:%M") That gives me an error saying undefined method `strftime' for "2010-12-30 19:26:00.000000":String And it dosn't do what i want with the days.. Edit: - @date = DateTime.strptime(news.entry_published, "%Y-%m-%d %H:%M:%S") = @date.strftime("%d/%m, %H:%M") Now works, and gives this output 30/12, 19:26 But i still have to check if it is today, yesterday or just another day. Cheers, Oluf.
