  • Local variable not being passed to partial template by render?

    - by brad
    I don't seem to be able to pass a variable to my partial template in rails (2.3.5). My code is as follows; In the main view .html.erb file: <% f.fields_for :payments do |payment_form| %> <%= render 'payment', {:f => payment_form, :t => "test" } %> <% end %> and in the _payment.html.erb file: <%= t %> produces a wrong number of arguments (0 for 1) error. The payment_form object is being passed to the partial as f without any problems. I've tried a number of variations on the above syntax (e.g. :locals => {:f => payment_form, :t => "test" } without success. I presume I'm doing something pretty basic wrong but just can't see it.

  • Most proper way to use inherited classes with shared scopes in Mongo?

    - by Trip
    I have the TestVisual class that is inherited by the Game class : class TestVisual < Game include MongoMapper::Document end class Game include MongoMapper::Document belongs_to :maestra key :incorrect, Integer key :correct, Integer key :time_to_complete, Integer key :maestra_id, ObjectId timestamps! end As you can see it belongs to Maestra. So I can do Maestra.first.games But I can not to Maestra.first.test_visuals Since I'm working specifically with TestVisuals, that is ideally what I would like to pull. Is this possible with Mongo. If it isn't or if it isn't necessary, is there any other better way to reach the TestVisual object from Maestra and still have it inherit Game ?

  • Rails: Best practice to store user settings?

    - by ole_berlin
    Hi, I'm wondering what the best way is to store user settings? For a web 2.0 app I want users to be able to select certain settings. At the moment is it only when to receive email notifications. The easiest way would be to just create a Model "Settings" and have a column for every setting and then have a 1-1 relationship with users. But is there a pattern to solve this better? Is it maybe better to store the info in the user table itself? Or should I use a table with "settings_name" and "settings_value" to be completely open about the type of settings stored there (without having to run any migrations when adding options)? What is your opinion? Thanks

  • Submit button outside form_for loop

    - by user1152142
    I have set up some horizontal tabs using twitter bootstrap and I am rendering a form inside each of the tabs: <div class="tab-content"> <div id="tab1" class="tab-pane active"> <%= render :partial => "shipdr/websites/form", locals: {:@shipdr_website => shipdr_website} %> </div> <div id="tab2" class="tab-pane"> Another form (not yet implemented) </div> <div id="tab3" class="tab-pane"> Another form (not yet implemented). </div> </div> Then in shipdr/websites/form I have: <%= simple_form_for(@shipdr_website) do |f| %> <% if @shipdr_website.errors.any? %> <div id="error_explanation"> <h2><%= pluralize(@shipdr_website.errors.count, "error") %> prohibited this shipdr_website from being saved:</h2> <ul> <% @shipdr_website.errors.full_messages.each do |msg| %> <li><%= msg %></li> <% end %> </ul> </div> <% end %> <div class="field"> <%= f.input :name %> </div> <div class="field"> <%= f.input :url %> </div> <div class="field"> <%= f.input :api_key %> </div> <div class="actions"> <%= f.submit nil, :class => "btn btn-primary" %> </div> <% end %> I want to move the submit button outside of the "tab-content" area so when a user clicks the submit button, all three forms area submitted. All forms will use that same model and the same action but will have different field. The idea is similar to a wizard except I am using tabs. Does anyone have any idea how I can move the submit button outside of the form_for loop and how I can submit the three forms with a single button?

  • what is the responsibility of ngnix or apache in rails application?

    - by user2177410
    How rails applications actually work? Let's say we have nginx + passenger + Ubuntu, so my questions are: What is nginx actually doing? How does it transfer requests to the rails app? what is passenger responsible for? And what is rack? How actually rails app can work just on webrick without apache? Please dont give me answers like "nginx processes the requests"; I need something more, or may be you know the source where I can read about this.

  • Missing Required Gems - javan-whenever and cron job in rails

    - by Matenia Rossides
    Hi, I have finally managed to get javan-whenever gem working on my site5 server, and updating the crontab is quite easy, however whenever a cron job is run with the code that is generated, i get a "missing required gems" error where it lists about 8/10 of my gems. Has anyone else had this problem? If so, what would the solution be. The funny thing is that when it outputs where my gems are, this is all correct, and the gems are loading fine from within my application. Cheers, Matenia

  • Rails 2.3.5: flash[:notice] disappears after redirect_to call

    - by xyzman
    Here I've got two controller methods: def invite if request.post? begin email = AccountMailer.create_invite(@user,url) AccountMailer.deliver(email) flash[:notice] = "Invitation email sent to #{@user.email}" rescue #mail delivery failed flash[:error] = "Failed to deliver invitation" end redirect_to :action => :show, :id => @user.id end end and def show @title = "User #{@user.full_name}" end The problem is, when I send an invitation, and get redirected to ./show, I see no messages at all. If I change redirect_to to render, the message appears. Still, isn't it intended for flash to work in the immediate subsequent requests? BTW, I'm using Rails+Passenger setup, could it be so that redirected request goes to another application instance?

  • DataMapper save fails but with no errors

    - by Justin Bozonier
    When I try to modify and then save a model using DataMapper I get a SaveFailure exception but no errors. Specifically I see this message: "MonthlyBill#save returned false, MonthlyBill was not saved" This is the code doing the saving: post '/monthly_bills' do with_authenticated_user do |user| description = params[:description] expected_amount = params[:expected_amount] pay_period = params[:pay_period] monthly_bill = MonthlyBill.new(:description=>description, :expected_amount=>expected_amount, :pay_period=>pay_period) user.MonthlyBills << monthly_bill user.save end The User model: class User include DataMapper::Resource property :id, Serial property :email_address, String property :password, String has n, :MonthlyBills has 1, :CurrentPayPeriod end The MonthlyBill model: class MonthlyBill include DataMapper::Resource property :id, Serial property :description, String property :expected_amount,Decimal property :pay_period, Integer belongs_to :user end What is the issue and, more importantly, how can I get DataMapper to tell me more specifically what is wrong?

  • How do you submit a rails 3 form without refreshing the page?

    - by Anthony H
    I've seen this done using ajax & php, but not rails 3. I've tried using: <%= form_for(:technician, :url => {:controller => 'pos', :action => 'create_ticket'}, :remote => true) do |f| %> but the page still refreshes each time. I'm building a point of sale program, so I don't want the page to refresh. How do I send the form data to the controller to process and store in the database without refreshing?

  • RSpec View testing: How to modify params?

    - by sebastiangeiger
    I am trying to test my views with RSpec. The particular view that is causing me troubles changes its appearance depending on a url parameter: link_to "sort>name", model_path(:sort_by => 'name') which results in http://mydomain/model?sort_by=name My view then uses this parameter like that: <% if params[:sort_by] == 'name' %> <div>Sorted by Name</div> <% end %> The RSpec looks like this: it "should tell the user the attribute for sorting order" do #Problem: assign params[:sort_for] = 'name' render "/groups/index.html.erb" response.should have_tag("div", "Sorted by Name") end I would like to test my view (without controller) in RSpec but I can't get this parameter into my params variable. I tried assign in all different flavours: assign[:params] = {:sort_by => 'name'} assign[:params][:sort_by] = 'name' ... no success so far. Every idea is appreciated.

  • sending specific data into a collection partial

    - by mikeglaz
    I have a User class with a has_many :messages and a Message class which belongs_to :user. In the Message controller's show action has the corresponding view: <% if @messages.any? %> <ol class="microposts"> <%= render partial: 'shared/message', collection: @messages %> </ol> <% end %> And the shared/_message.html.erb template looks like this: <li id="<%= message.id %>"> <span class="content"><%= message.body %></span> <% user_id = message.from %> <% user = User.find(user_id) %> From: <%= user.name %> </li> I feel like the following two lines should be done in the Messages controller from what I read in tutorials on Rails: <% user_id = message.from %> <% user = User.find(user_id) %> But how would I pass each message's corresponding from value (which stores user.id) into the partial? thanks, mike

  • How to copy a file using Paperclip

    - by CalebHC
    Does anyone know of a way to copy files with Paperclip using S3 for storage? Before I try to write my own, I just wanted to make sure there wasn't already a way to do this. Speaking of copying, is there an easier way of copying a whole model including all of its has_many relationships? Sorry for the second question but it kind of fits! :) Thanks

  • Modeling Buyers & Sellers in a Rails Ecommerce App

    - by MikeH
    I'm building a Rails app that has Etsy.com style functionality. In other words, it's like a mall. There are many buyers and many sellers. I'm torn about how to model the sellers. Key facts: There won't be many sellers. Perhaps less than 20 sellers in total. There will be many buyers. Hopefully many thousands :) I already have a standard user model in place with account creation and roles. I've created a 'role' of 'seller', which the admin will manually apply to the proper users. Since we'll have very few sellers, this is not an issue. I'm considering two approaches: (1) Create a 'store' model, which will contain all the relevant store information. Products would :belong_to :store, rather than belonging to the seller. The relationship between the user and store models would be: user :has_one store. My main problem with this is that I've always found has_one associations to be a little funky, and I usually try to avoid them. The app is fairly complex, and I'm worried about running into a cascade of problems connected to the has_one association as I get further along into development. (2) Simply include the relevant 'store' information as part of the user model. But in this case, the store-related db columns would only apply to a very small percentage of users since very few users will also be sellers. I'm not sure if this is a valid concern or not. It's very possible that I'm thinking about this incorrectly. I appreciate any thoughts. Thanks.

  • Forms blank when rendering a partial when using a collection of objects. Help!

    - by dustmoo
    Alright, I know my title is a little obscure but it best describes the problem I am having. Essentially, I have a list of users, and want to be able to edit their information in-line using AJAX. Since the users are showing up in rows, I am using a partial to render the data and the forms (which will be hidden initially by the ajax), however, when the rows are rendered currently only the last item has it's form's fields populated. I suspect this has something to do with the fact that all the form fields have the same id's and it is confusing the DOM. But I don't know how to make sure the id's are unique. Here is a small example: In my view: <%= render :partial => 'shared/user', :collection => @users %> My partial (broke down to just the form) note that I am using the local variable "user" <% form_for user, :html => {:multipart => true} do |f| -%> <%= f.label :name, "Name*" %> <%= f.text_field :title, :class => "input" %> <%= f.label :Address, "Address" %> <%= f.text_field :address, :class => "input" %> <%= f.label :description, "Description*" %> <%= f.text_area :description, :class => "input" %> <% end -%> When the html is rendered each form has a unique id (for the id of the user) but the elements themselves all have the same id, and only the last user form is actually getting populated with values. Does anyone have any ideas?? :) Thanks in advance!

  • How to stub Restul-authentication's current_user method?

    - by Thiago
    Hi there, I'm trying to run the following spec: describe UsersController, "GET friends" do it "should call current_user.friends" do user = mock_model(User) user.should_receive(:friends) UsersController.stub!(:current_user).and_return(user) get :friends end end My controller looks like this def friends @friends = current_user.friends respond_to do |format| format.html end end The problem is that I cannot stub the current_user method, as when I run the test, I get: Spec::Mocks::MockExpectationError in 'UsersController GET friends should call current _user.friends' Mock "User_1001" expected :friends with (any args) once, but received it 0 times[0m ./spec/controllers/users_controller_spec.rb:44: current_user is a method from Restful-authentication, which is included in this controller. How am I supposed to test this controller? Thanks in advance

  • Sharing code between two or more rails apps... alternatives to git submodules?

    - by jtgameover
    We have two separate rails_app, foo/ and bar/ (separate for good reason). They both depend on some models, etc. in a common/ folder, currently parallel to foo and bar. Our current svn setup uses svn:externals to share common/. This weekend we wanted to try out git. After much research, it appears that the "kosher" way to solve this is using git submodule. We got that working after separating foo,bar,common into separate repositories, but then realized all the strings attached: Always commit the submodule before committing the parent. Always push the submodule before pushing the parent. Make sure that the submodule's HEAD points to a branch before committing to it. (If you're a bash user, I recommend using git-completion to put the current branch name in your prompt.) Always run 'git submodule update' after switching branches or pulling changes. All these gotchas complicate things further than add,commit,push. We're looking for simpler ways to share common in git. This guy seems to have success using the git subtree extension, but that deviates from standard gitand still doesn't look that simple. Is this the best we can do given our project structure? I don't know enough about rails plugins/engines, but that seems like a possible RoR-ish way to share libraries. Thanks in advance.
