  • Remove a tag type from the view

    - by user284194
    I have an index view that lists all of the tags for my Entry and Message models. I would like to only show the tags for Entries in this view. I'm using acts-as-taggable-on. Tags Controller: def index @letter = params[:letter].blank? ? 'a' : params[:letter] @tagged_entries = Tagging.find_all_by_taggable_type('Entry').map(&:taggable) #@tagged_messages = Tagging.find_all_by_taggable_type('Message') #@tagged_messages = Tagging.find_all_by_taggable_type('Message').map(&:taggable) @title = "Tags" if params[:letter] == '#' @data = Tag.find(@tagged_entries, :conditions => ["name REGEXP ?", "^[^a-z]"], :order => 'name', :select => "id, name") else @data = Tag.find(@tagged_entries, :conditions => ["name LIKE ?", "#{params[:letter]}%"], :order => 'name', :select => "id, name") end respond_to do |format| flash[:notice] = 'We are currently in Beta. You may experience errors.' format.html end end tags#index: <% @data.each do |t| %> <div class="tag"><%= link_to t.name.titleize, tag_path(t) %></div> <% end %> I want to show only the taggable type 'Entry' in the view. Any ideas? Thank you for reading my question.

  • rake db:migrate not executing new migrations

    - by Matt H
    Hi guys. I'm trying to add some columns to an existing table, so I generated a migration that did so. When I run db:migrate the new migration isn't run and the table isn't updated. I've had this problem many times before, and it's getting bloody annoying. Output from rake db:migrate $ rake db:migrate --trace (in /Users/one/app) ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:migrate ** Invoke db:schema:dump (first_time) ** Invoke environment ** Execute db:schema:dump

  • BigDecimal to_s does not match to_f

    - by Chris Bisignani
    Is the BigDecimal class broken? It seems like the following should never, ever occur: Note that a.to_f != a.to_s.to_f a.class = BigDecimal a.to_f = 18658.1072928 a.to_s = "10865.81072928" b.class = BigDecimal b.to_f = 10000.0 b.to_s = "10000.0" (a - b).to_f = 865.81072928 a.to_f - b.to_f = 8658.1072928 Any ideas as to what might be going wrong?

  • How to count the length (number of lines) of a csv file in Rails?

    - by Mathias
    Hello, I have a form (Rails) which allows me to load a .csv file using the file_field. In the view: <% form_for(:upcsv, :html => {:multipart => true}) do |f| %> <table> <tr> <td><%= f.label("File:") %></td> <td><%= f.file_field(:filename) %></td> </tr> </table> <%= f.submit("Submit") %> <% end %> Clicking Submit redirects me to another page (create.html.erb). The file was loaded fine, and I was able to read the contents just fine in this second page. I am trying to show the number of lines in the .csv file in this second page. My controller (semi-pseudocode): class UpcsvController < ApplicationController def index end def create file = params[:upcsv][:filename] ... #params[:upcsv][:file_length] = file.length # Show number of lines in the file #params[:upcsv][:file_length] = file.size ... end end Both file.length and file.size returns '91' when my file only contains 7 lines. From the Rails documentation that I read, once the Submit button is clicked, Rails creates a temp file of the uploaded file, and the params[:upcsv][:filename] contains the contents of the temp/uploaded file and not the path to the file. And I don't know how to extract the number of lines in my original file. What is the correct way to get the number of lines in the file? My create.html.erb: <table> <tr> <td>File length:</td> <td><%= params[:upcsv][:file_length] %></td> </tr> </table> I'm really new at Rails (just started last week), so please bear with my stupid questions. Thank you!

  • Home_path issue with RoR testing locally on mobile device

    - by Amir
    When I use <%= link_to image_tag("foo.png"), home_path %> and display it on my localhost on my iPhone, it's broken. When I inspect on with firebug, the src of the image is http://localhost:3000/images/foo.png thus causing it to break on my iPhone. When I use <img src="/images/foo.png" /> it displays fine on my iPhone. I am pointing to the IP address of my PC running the server of my rails app in Safari. It's loading the text but all the css, JavaScript, and images are missing unless the path is absolute with using the rails default helpers. Is there a way to correct this path issue locally so it's absolute like /images/foo.png instead of http://localhost:3000/images/foo.png. Update CSS file paths are also affected. Instead of just making the path /stylesheets/foo.css, it's http://localhost:3000/stylesheets/foo.css. Update: Solution It's the Facebook plugin changing the asset host to the callback url of my facebook app settings which is currently set to http://localhost:3000/

  • Display pdf file inline in Rails app

    - by Martas
    Hi, I have a pdf file attachment saved in the cloud. The file is attached using attachment_fu. All I do to display it in the view is: <%= image_tag @model.pdf_attachment.public_filename %> When I load the page with this code in the browser, it does what I want: it displays the attached pdf file. But only on Mac. On Windows, browsers will display a broken image placeholder. Chrome's Developer Tools report: "Resource interpreted as image but transferred with MIME type application/pdf." I also tried sending the file from controller: in PdfAttachmentController: def send_pdf_attachment pdf_attachment = PdfAttachment.find params[:id] send_file pdf_attachment.public_filename, :type => pdf_attachment.content_type, :file_name => pdf_attachment.filename, :disposition => 'inline' end in routes.rb: map.send_pdf_attachment '/pdf_attachments/send_pdf_attachment/:id', :controller => 'pdf_attachments', :action => 'send_pdf_attachment' and in the view: <%= send_pdf_attachment_path @model.pdf_attachment %> or <%= image_tag( send_pdf_attachment_path @model.pdf_attachment ) %> And that doesn't display the file on Mac (I didn't try on Windows), it displays the path: pdf_attachments/send_pdf_attachment/35 So, my question is: what do I do to properly display a pdf file inline? Thanks martin

  • Which testing method to go with? [Rails]

    - by yuval
    I am starting a new project for a client today. I have done some rails projects before but never bothered writing tests for them. I'd like to change that starting with this new project. I am aware there are several testing tools, but am a bit confused as to which I should be using. I heard of RSpec, Mocha, Webrat, and Cucamber. Please keep in mind I never really wrote any regular tests, so my knowledge of testing in general is quite limited. How would you suggest I get started? Thanks!

  • Best way to create a preview functionality in rails

    - by slythic
    Hi all, I'm looking to implement a preview functionality in my posts scaffold. All I need to do is allow a user to enter information in the new view (/posts/new) and then replace the submit button with a preview button. Once the preview button is clicked, the user is routed to the preview page (probably /posts/new/preview). If the user wants to make a change they would click 'go back' or if they are happy with the post they can then submit the post. I found this article (http://eyedeal.team88.org/node/105) but it seems dated. Any ideas on what the best approach for this would be? Many thanks, Tony

  • Devise email confirmation from localhost

    - by John
    I am able to get the registration confirmation email to send out in deployment on Heroku, but when I try a registration on localhost:3000, I get the following error: undefined local variable or method `confirmed_at' for #<User:0xb67a1ff0> In my config/environments/production.rb file I have: config.action_mailer.default_url_options = { :host => 'xxxx.com' } And I have an initializer file with the following format: ActionMailer::Base.smtp_settings = { :user_name => "[email protected]", :password => "xxxxxx", :domain => "xxxx.com", :address => "smtp.sendgrid.net", :port => "xxx", :authentication => :plain, :enable_starttls_auto => true }; What settings do I need to get the localhost working? Thanks! John

  • Rails 3: How do I call a javascript function from a js.erb file

    - by user321775
    Now that I've upgraded to Rails 3, I'm trying to figure out the proper way to separate and reuse pieces of javascript. Here's the scenario I'm dealing with: I have a page with two areas: one with elements that should be draggable, the other with droppables. When the page loads I use jQuery to setup the draggables and droppables. Currently I have the script in the head portion of application.html.erb, which I'm sure is not the right solution but at least works. When I press a button on the page, an ajax call is made to my controller that replaces the draggables with a new set of elements that should also be draggable. I have a js.erb file that renders a partial in the correct location. After rendering I need to make the new elements draggable, so I'd like to reuse the code that currently lives in application.html.erb, but I haven't found the right way to do it. I can only make the new elements draggable by pasting the code directly into my js.erb file (yuck). What I'd like to have: - a javascript file that contains the functions prepdraggables() and prepdroppables() - a way to call either function from application.html.erb or from a js.erb file I've tried using :content_for to store and reuse the code, but can't seem to get it working correctly. What I currently have in the head section of application.html.erb <% content_for :drag_drop_prep do %> <script type="text/javascript" charset="utf-8"> $(document).ready(function () { // declare all DOM elements with class draggable to be draggable $( ".draggable" ).draggable( { revert : 'invalid' }); // declare all DOM elements with class legal to be droppable $(".legal").droppable({ hoverClass : 'legal_hover', drop : function(event, ui) { var c = new Object(); c['die'] = ui.draggable.attr("id"); c['cell'] = $(this).attr("id"); c['authenticity_token'] = encodeURIComponent(window._token); $.ajax({ type: "POST", url: "/placeDie", data: c, timeout: 5000 }); }}); }); </script> <% end %> undo.js.erb $("#board").html("<%= escape_javascript(render :partial => 'shared/board', :locals => { :playable => true, :restartable => !session[:challenge]}) %>") // This is where I want to prepare draggables. <%= javascript_include_tag "customdragdrop.js" %> // assuming this file had the draggables code from above in a prepdraggables() function prepdraggables();

  • An AuthLogic form is giving me incorrect validation errors -- why?

    - by sscirrus
    Hi everyone, I set up AuthLogic for Rails according to the AuthLogic example: http://github.com/binarylogic/authlogic_example. I can log on successfully to the system, but when accessing users/new.html.erb to register a new user, the form returns the following validation errors: Email is too short (minimum is 6 characters) Email should look like an email address. Login is too short (minimum is 3 characters) Login should use only letters, numbers, spaces, and .-_@ please. Password is too short (minimum is 4 characters) Password confirmation is too short (minimum is 4 characters) None of these errors exist in the data I am entering. # new.html.erb <%= form.label :login, nil, :class => "label" %><br /> <%= form.text_field :login, :class => "inputBox", :name => "login", :type => "text" %><br /> <%= form.label :password, form.object.new_record? ? nil : "Change password", :class => "label" %><br /> <%= form.password_field :password, :class => "inputBox", :name => "password", :type => "text" %><br /> <%= form.label "Confirm password", nil, :class => "label" %><br /> <%= form.password_field :password_confirmation, :class => "inputBox", :name => "password_confirmation", :type => "text" %><br /> <%= form.label :email, nil, :class => "label" %><br /> <%= form.text_field :email, :class => "inputBox", :name => "email", :type => "text" %><br /> # Users controller def new @user = User.new render :layout => "forms" end I think the problem is that the data isn't being transferred somehow and therefore AuthLogic doesn't think the inputs are sufficient. Do you have any idea why AuthLogic is telling me the data doesn't satisfy its validation?

  • Nested form using accepts_nested_attributes_for with pre-population from another table

    - by mikeydelamonde
    I'm using Rails 2.3.5 and have a nested structure as follows: Lists has_many Items Items_Features has_many Features Items_Features has_many Items Items_Features has a text field to hold the value of the feature Then I have a nested form with partials to update and display this so that it updates Lists, Items and Items_Features What I want to do is generate input fields for each of the rows in features so that the user can fill in a value and it gets inserted/updated in items_features. I also want a label next to the box to display the feature name. It might look like this: List name: Cheeses Item1 name: Edam Feature, hardness: - fill in - <= this list of features from feature table Feature, smell: - fill in - How can I interrupt the nice and easy accepts_nested_attributes_for system to display this as I want?

  • Unique keys for Sphinx along three vectors instead of two

    - by Brendon Muir
    I'm trying to implement thinking-sphinx across multiple 'sites' hosted under a single rails application. I'm working with the developer of thinking-sphinx to sort through the finer details and am making good progress, but I need help with a maths problem: Usually the formula for making a unique ID in a thinking-sphinx search index is to take the id, multiply it by the total number of models that are searchable, and add the number of the currently indexed model: id * total_models + current_model This works well, but now I also through an entity_id into the mix, so there are three vextors for making this ID unique. Could someone help me figure out the equation to gaurantee that the id's will never collide using these three variables: id, total_models, total_entities The entity ID is an integer. I thought of: id * (total_models + total_entities) + (current_model + current_entity) but that results in collisions. Any help would be greatly appreciated :)

  • Datamapper In Memory Database

    - by Daniel Ribeiro
    It is easy to setup Datamapper with a Sqlite3 in memory database with: DataMapper.setup :default, 'sqlite3::memory:'. However, when testing, I'd like to destroy the whole in memory database after each test, instead of invoking automigrate! as a shortcut on dropping everything. Is it possible? Or is it enough to set the default repository to nil, and let the garbage collector dispose of it?

  • How to pre-check checkboxes in formtastic

    - by trustfundbaby
    I have a form I'm trying to set up ... Users can have many posts, and each post can have many people watching it. The Watch model is set up polymorphically as 'watchable' so it can apply to different types of models. It has a user_id, watchable_id, watchable_type and timestamps as attributes/fields. This is soley so that when people comment on a post, users watching the post can get an email about it. What I'm trying to do is show the user a list of users that they can tag on each post, which is not problem. This is what I'm using right now http://pastie.org/940421 The problem with this, is that when you go to edit an update/post ... all the checkboxes are prechecked ... I want it to pre-check only users who are currently watching the post.

  • Hot deploy on Heroku with no downtime

    - by zetarun
    A bad side of pushing to Heroku is that I must push the code (and the server restarts automatically) before running my db migrations. This can obviously cause some 500 errors on users navigating the website having the new code without the new tables/attributes: the solution proposed by Heroku is to use the maintenance mode, but I want a way with no downside letting my webapp running everytime! Is there a way? For example with Capistrano: I prepare the code to deploy in a new dir I run (backward) migrations and the old code continue to work perfectly I swith mongrel instance to the new dir and restart the server ...and I have no downtime!

  • Is Cancan's accessible_by my best choice for altering admin scope on the fly?

    - by evanchurchill
    Situation: On my site, I have a comment model, with a deleted field. Users cannot see deleted comments, but I would like to allow admins to see deleted comments, if they choose to. This will be accomplished by having a scope for users with the admin role which allows them to view comments with the deleted field set to false, as well as true. Question: Is Cancan's accessible_by method my best choice for doing so? From what I've read, it sounds like it will facilitate exactly what I'm trying to do, but, I don't want to implement something that is inefficient, if there is a better method.

  • Rails best practice on conditional parameters in a controller action

    - by randombits
    I have a controller create action looks for one or more parameters in the following ruleset. Let's say we have two parameters, foo and bar. The rules are the following: 1) if foo doesn't exist in the parameter list, bar must. 2) if bar doesn't exist in the parameter list, foo must. 3) they can both co-exist. they can't both be omitted (that's redundant with my rules above :) ) Can anyone show an example in Rails on how this is handled in the controller? Should I use a before_filter? Would appreciate some guidance as this isn't something that ActiveRecord validates.. so I'd need to build an error message to the user directly from controller logic, not model logic. For bonus points, I output the error in XML, so if you can show how that's done, that'd be great. Hypothetically let's call the resource "Lorem", so it is created via http://foo/lorem.xml and we have lorem_controller.rb.

  • Rails render partial with block

    - by brad
    I'm trying to re-use an html component that i've written that provides panel styling. Something like: <div class="v-panel"> <div class="v-panel-tr"></div> <h3>Some Title</h3> <div class="v-panel-c"> .. content goes here </div> <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div> </div> So I see that render takes a block. I figured then I could do something like this: # /shared/_panel.html.erb <div class="v-panel"> <div class="v-panel-tr"></div> <h3><%= title %></h3> <div class="v-panel-c"> <%= yield %> </div> <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div> </div> And I want to do something like: #some html view <%= render :partial => '/shared/panel', :locals =>{:title => "Some Title"} do %> <p>Here is some content to be rendered inside the panel</p> <% end %> Unfortunately this doesn't work with this error: ActionView::TemplateError (/Users/bradrobertson/Repos/VeloUltralite/source/trunk/app/views/sessions/new.html.erb:1: , unexpected tRPAREN old_output_buffer = output_buffer;;@output_buffer = ''; __in_erb_template=true ; @output_buffer.concat(( render :partial => '/shared/panel', :locals => {:title => "Welcome"} do ).to_s) on line #1 of app/views/sessions/new.html.erb: 1: <%= render :partial => '/shared/panel', :locals => {:title => "Welcome"} do -%> ... So it doesn't like the = obviously with a block, but if I remove it, then it just doesn't output anything. Does anyone know how to do what I'm trying to achieve here? I'd like to re-use this panel html in many places on my site.
