  • 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 can I change Rails view code for site visitors using SSL?

    - by pjmorse
    My Rails app has some pages which are SSL-required and others which are SSL-optional. The optional pages use some assets which are served off-site (images from a vendor) which have both http and https URLs. I need to use https when the page is accessed via SSL to avoid the dreaded "this page contains both secure and insecure elements" warning. I've written code to return the image URLs as http by default and https if requested. My problem now is determining in the view how the request came in. request.ssl? doesn't work in views. I've tried using a before_filter which sets something like @ssl_request using request.ssl?, but that also always returns false. Is there a more elegant way to do this? The server stack is Nginx and Passenger. Other apps with Apache = Mongrel stacks pass an X_FORWARDED_PROTO header to tell Rails that SSL is or isn't being used; is it possible that Nginx/Passenger doesn't do this?

  • Rails - How do you test ActionMailer sent a specific email in tests

    - by adam
    Currently in my tests I do something like this to test if an email is queued to be sent assert_difference('ActionMailer::Base.deliveries.size', 1) do get :create_from_spreedly, {:user_id => @logged_in_user.id} end but if i a controller action can send two different emails i.e. one to the user if sign up goes fine or a notification to admin if something went wrong - how can i test which one actually got sent. The code above would pass regardless.

  • how do I join and include the association

    - by Mark
    Hi All, How do I use both include and join in a named scope? Post is polymorphic class Post has_many :approved_comments, :class_name => 'Comment' end class Comment belongs_to :post end Comment.find(:all, :joins => :post, :conditions => ["post.approved = ? ", true], :include => :post) This does not work as joins does an inner join, and include does a left out join. The database throws an error as both joins can't be there in same query.

  • Are there other search options for heroku

    - by Jonathan
    I am about to launch a beta site, and heroku looks like a great option. The only think that is getting me down is that the only search option is $20/mth for the Websolr add-on. I am sure that Websolr is great, but at this very early point in this project, I rather not light up that expense. Are there any free search options to couple with heroku's Blossom (free) plan. I feel like such a cheapskate!

  • Clearly defined Rails routing problem - undefined method for Nil:NilClass

    - by sscirrus
    Guys and girls, I have been working on this problem for a while but still no joy. This is my second question within this general area, because the last question was getting too long and this is now more well-defined. Summary of the Problem: I am loading a page for my customers and I get error: undefined method 'name' for Nil:NilClass My Code #Link on views/users/show.html.erb: <%= link_to "Customer Account", :action => "home", :controller => "customers", :id => @user.user_type_id %> #Regular Route: map.connect 'customers/home/:id', :controller => 'customers', :action => 'home' #Rake Routes, first entry: /customers/home/:id :controller=>:"customers", :action=>"home" #Customers Controller: def home render :layout => 'home' @customer = Customer.find(params[:id]) @user = @current_user_session.user flash[:error] = "Customer not found" and return unless @customer @jobs = @customer.jobs end #views/customers/home.html.erb: <%= @customer.name %> I have absolutely no idea why this seemingly clear sequence of events is resulting in a NilClass. Search the console for Customer.find(2) returns the correct customer. What is this noob missing? Thank you very much.

  • Rails3 renders a js.erb template with a text/html content-type instead of text/javascript

    - by Yannis
    Hi, I'm building a new app with 3.0.0.beta3. I simply try to render a js.erb template to an Ajax request for the following action (in publications_controller.rb): def get_pubmed_data entry = Bio::PubMed.query(params[:pmid])# searches PubMed and get entry @publication = Bio::MEDLINE.new(entry) # creates Bio::MEDLINE object from entry text flash[:warning] = "No publication found."if @publication.title.blank? and @publication.authors.blank? and @publication.journal.blank? respond_to do |format| format.js end end Currently, my get_pubmed_data.js.erb template is simply alert('<%= @publication.title %>') The server is responding with the following alert('Evidence for a herpes simplex virus-specific factor controlling the transcription of deoxypyrimidine kinase.') which is perfectly fine except that nothing happen in the browser, probably because the content-type of the response is 'text/html' instead of 'text/javascript' as shown by the response header partially reproduced here: Status 200 Keep-Alive timeout=5, max=100 Connection Keep-Alive Transfer-Encoding chunked Content-Type text/html; charset=utf-8 Is this a bug or am I missing something? Thanks for your help!

  • 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

  • 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?

  • 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.

  • where from does paperclip get the name of original file?

    - by Pavel K.
    i started using nginx upload module (which creates upload files like /tmp/000121545) but i need paperclip to use original filename while saving files (like /public/avatars/LuckyLuke.jpg) previously in the parameters Rails were passing just "avatar"=>#<File:/tmp/RackMultipart20100413-6151-t3ecq0-0> no original filename as well, so i am wondering where from does it come in paperclip? i tried looking through plugin code but it's currently a bit too complex for me.

  • Two Tables Serving as one Model in Rails

    - by matsko
    Is is possible in rails to setup on model which is dependant on a join from two tables? This would mean that for the the model record to be found/updated/destroyed there would need to be both records in both database tables linked together in a join. The model would just be all the columns of both tables wrapped together which may then be used for the forms and so on. This way when the model gets created/updated it is just one form variable hash that gets applied to the model? Is this possible in Rails 2 or 3?

  • Using fields from an association (has_many) model with formtastic in rails

    - by pduersteler
    I searched and tried a lot, but I can't accomplish it as I want.. so here's my problem. class Moving < ActiveRecord::Base has_many :movingresources, :dependent => :destroy has_many :resources, :through => :movingresources end class Movingresource < ActiveRecord::Base belongs_to :moving belongs_to :resource end class Resource < ActiveRecord::Base has_many :movingresources has_many :movings, :through => :movingresources end Movingresources contains additional fields, like "quantity". We're working on the views for 'bill'. Thanks to formtastic to simplify the whole relationship thing by just writing <%= form.input :workers, :as => :check_boxes %> and i get a real nice checkbox list. But what I haven't found out so far is: How can i use the additional fields from 'movingresource', next or under each checkbox my desired fields from that model? I saw different approaches, mainly with manually looping through an array of objects and creating the appropriate forms, using :for in a form.inputs part, or not. But none of those solutions were clean (e.g. worked for the edit view but not for new because the required objects were not built or generated and generating them caused a mess). I want to know your solutions for this! :-)

  • Using a join model to relate a model to itself

    I have two models: User MentoringRelationship MentoringRelationship is a join model that has a mentor_id column and a mentee_id column (both of these reference user_ids from the users table). How can I specify a relation called 'mentees' on the User class that will return all of the users mentored by this user, using the MentoringRelationships join table? What relations do we need to declare in the User model and in the MentoringRelationship model?

  • Excessive httpd processes to stack up on my Rails + Apache2 + Passenger production setup?

    - by LeoAlmighty
    I have a Rails + Apache2 + Postgres + Passenger application running in production mode in OSX Snow Leopard. The application serves as a data warehouse for another application in the cloud so I'm constantly getting API calls to my OSX production build. After a recent reboot, I'm finding a ton of httpd processes stacking up and eventually requiring an apache reboot. I haven't changed any settings, everything was running fine before. Any ideas on the best way to troubleshoot this? $ ps -ef|grep httpd 0 6203 1 0 0:00.20 ?? 0:00.47 /usr/sbin/httpd -D FOREGROUND 70 6222 6203 0 0:00.05 ?? 0:00.11 /usr/sbin/httpd -D FOREGROUND 70 6224 6203 0 0:00.31 ?? 0:00.50 /usr/sbin/httpd -D FOREGROUND 70 6233 6203 0 0:00.05 ?? 0:00.10 /usr/sbin/httpd -D FOREGROUND 70 6234 6203 0 0:00.43 ?? 0:00.64 /usr/sbin/httpd -D FOREGROUND 70 6243 6203 0 0:00.02 ?? 0:00.03 /usr/sbin/httpd -D FOREGROUND 70 6319 6203 0 0:00.08 ?? 0:00.16 /usr/sbin/httpd -D FOREGROUND 70 6334 6203 0 0:00.02 ?? 0:00.05 /usr/sbin/httpd -D FOREGROUND 70 6469 6203 0 0:00.04 ?? 0:00.08 /usr/sbin/httpd -D FOREGROUND 70 6487 6203 0 0:00.36 ?? 0:00.48 /usr/sbin/httpd -D FOREGROUND 70 6593 6203 0 0:00.36 ?? 0:00.48 /usr/sbin/httpd -D FOREGROUND 70 6709 6203 0 0:00.04 ?? 0:00.08 /usr/sbin/httpd -D FOREGROUND 70 6718 6203 0 0:00.04 ?? 0:00.10 /usr/sbin/httpd -D FOREGROUND 70 6834 6203 0 0:00.01 ?? 0:00.03 /usr/sbin/httpd -D FOREGROUND 70 6852 6203 0 0:00.00 ?? 0:00.00 /usr/sbin/httpd -D FOREGROUND 70 6853 6203 0 0:00.01 ?? 0:00.02 /usr/sbin/httpd -D FOREGROUND

  • Override transparency color when converting transparent PNG to JPG

    - by Alexander Malfait
    I'm using Dragonfly to generate thumbnail images in a Rails app. I'm serving all picture images as JPG's. Now the client is uploading transparent PNG files, like this one: http://www.ibanez.co.jp/products/images/eg2010/ART120_TRF_12_02.png Dragonfly uses RMagick to convert these images to JPG. The problem is that it converts the PNG images to JPG with a black background, and my site's design requires a white background. I've tried to override it like this: encoded_image = Magick::Image.from_blob(image.data).first if encoded_image.format.downcase == format image # do nothing else encoded_image.format = format encoded_image.background_color = "white" encoded_image.transparent_color = "white" encoded_image.to_blob end But the produced JPG images still contain a black background. Does anyone know how to beat RMagick into using a white background when converting the transparent layer? I know I could just serve as PNG, but then the images are 10 times as large, and the site is already pretty bandwidth heavy.

  • Rails: Getting rid of "X is invalid" validation errors

    - by DJTripleThreat
    I have a sign-up form that has nested associations/attributes whatever you want to call them. My Hierarchy is this: class User < ActiveRecord::Base acts_as_authentic belongs_to :user_role, :polymorphic => true end class Customer < ActiveRecord::Base has_one :user, :as => :user_role, :dependent => :destroy accepts_nested_attributes_for :user, :allow_destroy => true validates_associated :user end class Employee < ActiveRecord::Base has_one :user, :as => :user_role, :dependent => :destroy accepts_nested_attributes_for :user, :allow_destroy => true validates_associated :user end I have some validation stuff in these classes as well. My problem is that if I try to create and Customer (or Employee etc) with a blank form I get all of the validation errors I should get plus some Generic ones like "User is invalid" and "Customer is invalid" If I iterate through the errors I get something like: user.login can't be blank User is invalid customer.whatever is blah blah blah...etc customer.some_other_error etc etc Since there is at least one invalid field in the nested User model, an extra "X is invalid" message is added to the list of errors. This gets confusing to my client and so I'm wondering if there is a quick way to do this instead of having to filer through the errors myself.
