  • Reloading an object not working in rspec

    - by Eric Baldwin
    I am trying to test a controller method with the following code: it "should set an approved_at date and email the campaign's client" do @campaign = Campaign.create(valid_attributes) post :approve, id: @campaign.id.to_s @campaign.reload @campaign.approved_at.should_not be(nil) end However, when I run this test, I get the following error: Failure/Error: @campaign.reload ActiveRecord::RecordNotFound: Couldn't find Campaign without an ID When I run the analagous lines in the rails console, the reload works and the value is set as I need it to be. Why isn't reload working for me when I run the code in an rspec test?

  • Rails: i would need to load a haml file in a class and render in the caller

    - by Totty
    I have this: app/modules/grid_module.rb app/modules/grid.html.haml then in my view: app/views/layouts/default.html.haml I want to make a new instance of the grid_module and render it content. Its content is into the grid.html.haml and this file can only use the instance vars set in the grid_module.rb is this possible to do? (the grid name is just an example, it must be more flexible, to load the html.haml file based on the .rb class) the grid_module must has access to models too* like this: User.find_by_id(4) thanks for help

  • Rails attribute alias

    - by Dr1Ku
    Hi, I was just wondering if it's possible to "rename" an association in Rails. Let's assume : # An ActiveRecord Class named SomeModelASubModel (some_model_a_sub_model.rb) class SomeModelASubModel < ActiveRecord::Base has_many :some_model_a_sub_model_items end # An ActiveRecord Class named SomeModelASubModelItem (some_model_a_sub_model_item.rb) class SomeModelASubModelItem < ActiveRecord::Base belongs_to :some_model_a_sub_model end At this point, calling some_model.items, where some_model is an instance of the SomeModelASubModel Class would trigger an undefined method error. What is the best practice for making this happen though, e.g. : # With a method_alias or something, would it be possible to : some_model = SomeModelASubModel.first # for instance items = some_model.items # For the reason stated, this doesn't work, one has to call : items = some_model.some_model_a_sub_model_items Is such a shorthand possible ? Thank you in advance !

  • Problem with displaying usernames in my flash[:notice] - Agile Web Development With Rails - Chapter

    - by Lee
    I can't figure out what I'm doing wrong here. I can’t seem to get the #{@user.name} to work in my flash[:notice] Everything else works just fine I can add new users, but when I add a new user instead of saying “User John Doe was successfully created”, it says “User #{@user.name} was successfully created.” I'm at this point in the depot app: depot_p/app/controllers/users_controller.rb to work.

  • rails + paperclip: Is a generic "Attachment" model a good idea?

    - by egarcia
    On my application I've several things with attachments on them, using paperclip. Clients have one logo. Stores can have one or more pictures. These pictures, in addition, can have other information such as the date in which they were taken. Products can have one or more pictures of them, categorized (from the font, from the back, etc). For now, each one of my Models has its own "paperclip-fields" (Client has_attached_file) or has_many models that have attached files (Store has_many StorePictures, Product has_many ProductPictures) My client has also told me that in the future we might be adding more attachments to the system (i.e. pdf documents for the clients to download). My application has a rather complex authorization system implemented with declarative_authorization. One can not, for example, download pictures from a product he's not allowed to 'see'. I'm considering re-factoring my code so I can have a generic "Attachment" model. So any model can has_many :attachments. With this context, does it sound like a good idea? Or should I continue making Foos and FooPictures?

  • How can I use form_remote_tag to update an acts_as_taggable_on field?

    - by Angela
    I have a model called Company which is acts_as_taggable_on. When I am /SHOWing a Company (e.g. company/15) I want to be able to see a form that allows me to add tags. I suppose this would be easier by just allowing at edit but sometimes I want to go back and just add tags. This is what I tried to do and I get an error: <div id = 'tags'> <strong>Tags:</strong> <% form_remote_tag(:url => {:action => 'update'}, :update => 'tags') do %> <%= text_field :company, :tag_list %> <%= submit_tag 'Save' %> <% end %> </div> Thanks!

  • How can I dynamically define the named route in a :partial in rails?

    - by Angela
    I have the following partial. It can be called from three different times in a view as follows: <%= render :partial => "contact_event", :collection => @contacts, :locals => {:event => email} %> Second time: <%= render :partial => "contact_event", :collection => @contacts, :locals => {:event => call} %> Third time: <%= render :partial => "contact_event", :collection => @contacts, :locals => {:event => letter} %> In each instance, call, email, letter refer to a specific instance of a Model Call, Email, or Letter. Here is the content of the partial "contact_event": <%= link_to_remote "Skip #{event} Remote", :url => skip_contact_email_url(contact_event, event), :update => "update-area-#{contact_event.id}-#{event.id}" %> <span id='update-area-<%="#{contact_event.id}-#{event.id}"%>'> </span> </p> My challenge: skip_contact_email_url only works when the event refers to an email. How can I dynamically define skip_contact_email_url to be skip_contact_letter_url if the local variable is letter? Even better, how can I have a single named route that would do the appropriate action?

  • How to set up two models having a has_many association with each other

    - by daz13
    I'm looking for a suggestion on how to set up two models, Teacher and Subject. A Teacher can have many Subjects, and a Subject can have many Teachers. Another thing to consider in the relationship between the two models is that a Teacher can create a Subject and add other Teachers to the Subject. I think I'm solid on the basics of the set up for each model: for teacher.rb: has_many :subjects for subject.rb: has_many :teachers and the teachers table should have a subject_id column and the subject table should have a teacher_id column. What I'm not sure about is how to set up the views (and corresponding controller methods) to allow the addition of a Teacher to a Subject. Any suggestions (or links to examples) are greatly appreciated. I haven't been able to find anything on this exact case.

  • Rails Nested Attributes Doesn't Insert ID Correctly

    - by MunkiPhD
    I'm attempting to edit a model's nested attributes, much as outline here, replicated here: <%= form_for @person do |person_form| %> <%= person_form.text_field :name %> <% for address in @person.addresses %> <%= person_form.fields_for address, :index => address do |address_form|%> <%= address_form.text_field :city %> <% end %> <% end %> <% end %> In my code, I have the following: <%= form_for(@meal) do |f| %> <!-- some other stuff that's irrelevant... --> <% for subitem in @meal.meal_line_items %> <%= f.fields_for subitem, :index => subitem do |line_item_form| %> <%= line_item_form.label :servings %><br/> <%= line_item_form.text_field :servings %><br/> <%= line_item_form.label :food_id %><br/> <%= line_item_form.text_field :food_id %><br/> <% end %> <% end %> <%= f.submit %> <% end %> This works great, except, when I look at the HTML, it's creating the inputs that look like the following, failing to input the correct id and instead placing the memory representation(?) of the model: <input type="text" value="2" size="30" name="meal[meal_line_item][#<MealLineItem:0x00000005c5d618>][servings]" id="meal_meal_line_item_#<MealLineItem:0x00000005c5d618>_servings">

  • Caching Models in rails

    - by jules
    I have a rails application, with a model that is a kind of repository. The records stored in the DB for that model are (almost) never changed, but are read all the time. Also there is not a lot of them. I would like to store these records in cache, in a generic way. I would like to do something like acts_as_cached, but here are the issue I have: I can not find a decent documentation for acts as cached (neither can I find it's repository) I don't want to use memcached, but something simpler (static variable, or something like that). Do you have any idea of what gems I could use to do that ? Thanks

  • fieldWithErrors not wrapping every error field

    - by Teef L
    Notice the following result when I submit blank :title and :description fields The validations are in the controller: class Question < ActiveRecord::Base validates_presence_of :title validates_presence_of :description And, the form is generated with those names: -form_for(@question) do |f| = f.error_messages = f.label :title = f.text_field :title, :size => 50, :onchange => remote_function(:url => {:action => :display_tag_suggestions}, :with => 'Form.Element.serialize(this)') #suggestions = f.label :description = f.text_area :description ... But, for some reason, only :title gets wrapped in the error div tags: <form action="/questions" class="new_question" id="new_question" method="post"> <div style="margin:0;padding:0"><input name="authenticity_token" type="hidden" value="6HQaiu1D0gBQcKw2pLeZP6Jvn0FSClPD5Sk9HwegzPg=" /></div> <div class="errorExplanation" id="errorExplanation"> <h2>2 errors prohibited this question from being saved</h2> <p>There were problems with the following fields:</p> <ul> <li>Title can't be blank</li> <li>Description can't be blank</li> </ul> </div> <label for="question_title">Title</label> <div class="fieldWithErrors"><input id="question_title" name="question[title]" onchange="new Ajax.Request('/questions/display_tag_suggestions', {asynchronous:true, evalScripts:true, parameters:Form.Element.serialize(this) + '&amp;authenticity_token=' + encodeURIComponent('6HQaiu1D0gBQcKw2pLeZP6Jvn0FSClPD5Sk9HwegzPg=')})" size="50" type="text" value="" /></div> <label for="question_description">Description</label> <textarea cols="40" id="question_description" name="question[description]" rows="20"></textarea> ... I don't think that behavior is expected. The problem most people have is that it's wrapping things with divs, which won't display properly. My problem is that fields aren't being wrapped with divs to begin with! I haven't made any (conscious) changes to how errors are handled, so I'm not sure why it's not working properly.

  • Speech recognition webservice that scores the accuracy of one audio clips vs. another?

    - by wgpubs
    Does such a thing exist? Building a Rails based web application where users can upload an audio file of them speaking that then needs to be compared to another audio file for the purposes of determining how similar to voices are. Ideally I'd like to simply get a response that gives me a score of how similar they are in terms of percentage (e.g. 75% similar etc...). Anyone have any ideas? Thanks

  • paperclip plugin not support for I18n

  • for TimeWithZone object, how to change the zone part only?

    - by leomayleomay
    I have a table Coupon with a field expired_at, which is of datetime type, and before I save the record, I want to change the zone part of the field according to the user's choice. Say, c = Coupon.new c.expired_at = DateTime.now c.expired_at_timezone = "Arizona" c.save! and in the coupon.rb class Coupon << ActiveRecord::Base def before_save # change the zone part here, leave the date and time part alone end end What I'm saying is if the admin want the coupon expired at 2014-07-01 10:00 am, Arizona time, the expired_at stored in the db should be like this: Tue, 01 Jul 2014 10:00:00 MST -07:00 is there any way I can modify the zone part only and leave the date and time part alone? Thanks

  • Accessing two sides of a user-user relationship in rails

    - by Lowgain
    Basically, I have a users model in my rails app, and a fanship model, to facilitate the ability for users to become 'fans' of each other. In my user model, I have: has_many :fanships has_many :fanofs, :through => :fanships In my fanship model, I have: belongs_to :user belongs_to :fanof, :class_name => "User", :foreign_key => "fanof_id" My fanship table basically consists of :id, :user_id and :fanof_id. This all works fine, and I can see what users a specific user is a fan of like: <% @user.fanofs.each do |fan| %> #things <% end %> My question is, how can I get a list of the users that are a fan of this specific user? I'd like it if I could just have something like @user.fans, but if that isn't possible what is the most efficient way of going about this? Thanks!

  • Rails show view of one model with form for adding one child - nested attributes vs seperate controll

    - by SWR
    I have a basic two tiered model structure: Articles - Comments with one Article having many comments. What is the best way to add a "Add a comment" form to the bottom of the Articles show page? nested_attributes is overkill as I don't want to be able to edit all of the comments on the page, just to add one more. Is the best way even with Rails 2.3 still to make a separate controller and embed a form_for pointing to the other controller into the Articles show view? If so, how do I get validation errors to return to the article display page? I don't want to make a separate comment page/view... thanks

  • To use an api or store a large dataset in a rails app?

    - by Dave
    Hi all- I am working on a site that has the potential to need a LOT of space. Basically we hope to have every video game every created stored in a database along with an image of the cover. There are some api's out there that might be able to help, like GiantBomb's (www.giantbomb.com). We are trying to decide whether to store the data locally and if so where to find that comprehensive a list, or make calls to the api on demand. The problem with the latter is likely latency and also downtime problems. Assuming we want to store it locally here are the questions: 1) Where can we find this kind of data (yes, I looked on google, and no I couldnt find anything:)) 2) What is the most efficient way to encode and store the images? Thanks!

  • How do I pass object values with render :action => 'new'

    - by PlanetMaster
    Hi, In an app I have the following: def new @property = Property.new(:country_id => 1, :user_id => current_user.id, :status_id => 'draft') end def create @property = Property.new(params[:property]) if @property.save flash[:success] = t('The_property_is_successfully_created') redirect_to myimmonatie_url else flash.now[:error]=t("The_property_could_not_be_created") render :action => 'new' end end When an error accors, the line render :action = 'new' gets executed, but the my form gives an error: user blank country blank These cannot be blank (defined in model), meaning this code: @property = Property.new(:country_id => 1, :user_id => current_user.id, :status_id => 'draft') is not executed anymore. What is the reason and solution? Thanks!
