| Changing Spree from_address Posted: 08 Oct 2016 07:05 AM PDT I am trying to change Spree 3.0 from_email I added this line to my spree initialiser, but it does not work: Spree::Store.current.mail_from_address = "x@x.com"
Do you know of any reason why not? I also put it directly in my mailer decorator: Spree::OrderMailer.class_eval do def confirm_email_to_store(order, resend = false) Spree::Store.current.mail_from_address = "x@x.com" @order = order.respond_to?(:id) ? order : Spree::Order.find(order) subject = (resend ?

| Proper way of using sass with Rails Posted: 08 Oct 2016 06:37 AM PDT At first, I have written all css styles in one file but things get complicated so I have divided my sass files to folders. I found an article from internet and I followed it. It says "if we put _ in front of sass file, it will not indexed by compiler" - Created 3 folders
- Created files _test_name.scss like that
- Created _index.scss file for every folder and import all other scss files in that folder
- Created main.scss file and import all index.scss files in it.
Everything is working fine but if I use color variable in somewhere in other folder it didn't wok. It gave me undefined variable error message. After that I imported colors scss file then it worked. But that's strange right? It should work without importing colors scss file. Now the thing is if I see my styles in developer tools, the same style repeating three times! Please check image

| Rails AJAX remote: true with dynamic id Posted: 08 Oct 2016 05:30 AM PDT I implemented a basic AJAX Call in Rails, which is working fine with this: index.html.erb <a href="/days/new" data-remote="true" id="new_day_ajax">Add This day</a>
new.js.erb $('#new_day_ajax').hide().after('<%= j render("form")%>');
The problem is I generate up to 31 a-tags like the above one on a single page with the following loop and the form will of course always show up at the first one, no matter which link I click: end_date.downto(start_date).each do |date| [...]
To make the form show up at the clicked link I tried to generate the ids dynamically like so: id="new_day_ajax_<%= date.strftime('%d') %>" <!-- i.e. new_day_ajax_07 -->
but now I don't know how to pass this dynamic id into the new.js.erb. How can I know the dynamic id inside of the javascript? Thanks in advance! |
| Rails create join table object should not create but update in special case Posted: 08 Oct 2016 04:41 AM PDT In a webshop I have a booking that needs to know if a booking already exists in the order. I had the whole thing working, but then the details... ...now 'booking on a product' (or in normal English: Adding a product to your shopping-cart) adds a totally new booking on the order list in each case. It oughtn't when this product is already booked once, then it only should alter the quantity. So easy right? Just one simple if-statement and the whole thing works. def create @order = current_order # If product has already been booked if @order.bookings.where(product_id: params[:product_id]).exists? # Then: Only alter the quantity in the booking. @booking = @order.bookings.where(product_id: params[:product_id]) @booking.product_quantity = params[:product_quantity] else # Else: Make a new booking. @booking = @order.bookings.new(booking_params) @product = @booking.product @booking.product_name = @product.name @booking.product_price = @product.price end @order.sum_all_bookings @order.save end # ... def booking_params params.require(:booking).permit(:product_quantity, :product_id) end
Doesn't seem to work. How do I make the check in the if-statement? Or should I go about a whole different route to update the booking? |

| Additive scope conditions for has_many :through Posted: 08 Oct 2016 04:27 AM PDT I want a user to be able to find all posts that have one or more tags. And I'd like the tags to be additive criteria, so for example you could search for posts that have just the 'News' tag, or you could search for posts that have both the 'News' and 'Science' tags. Currently what I have, and it works, is a Post model, a Tag model, and a join model called Marking. Post has_many :tags, through: :markings. I get what I need by passing an array of Tag ids to a Post class method: post.rb def self.from_tag_id_array array post_array = [] Marking.where(tag_id: array).group_by(&:post_id).each do |p_id,m_array| post_array << p_id if m_array.map(&:tag_id).sort & array.sort == array.sort end where id: post_array end

| Setting up Foreign Keys in Rails with Postgres Posted: 08 Oct 2016 12:16 AM PDT I am attempting to track mutual likes where a user likes a user that likes them. To check if the like is mutual, I call an method after the like is created. If that liker has been a likee than it is considered mutual. The problem however, is that I run into some odd errors that I believe are related to how the foreign keys have been set up. I have set up a has many association in Rails but any time I attempt to access it, I get a PG::InFailedSqlTransaction: ERROR: current transaction is aborted, commands ignored until end of transaction block : RELEASE SAVEPOINT active_record_1 error.

I've tried changing the hook to be around save, etc. but that doesn't work either. Also, I cannot even call Like.first else I get the same error. I've tried printing out liker.likes.where(likee: liker) and i get PG::UndefinedColumn: ERROR: column likes.user_id does not exist which I think is the problem. I can however, access the liker like this: self.likee inside of the hook but I cannot call self.likee.likes without it returning #<Like::ActiveRecord_Associations_CollectionProxy:0x3fd91ca5ca78> Schema: create_table "likes", force: :cascade do |t| t.integer "liker_id", null: false t.integer "likee_id", null: false t.integer "connection_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.index ["likee_id"], name: "index_likes_on_likee_id", using: :btree t.index ["liker_id"], name: "index_likes_on_liker_id", using: :btree end create_table "users", force: :cascade do |t| t.string "email" t.string "username" t.string "password_digest" t.boolean "admin", default: false t.index ["email"], name: "index_users_on_email", using: :btree t.index ["username"], name: "index_users_on_username", using: :btree end

I have another app that's running with virtually the same production.rb file and it's sending the image without issue, so I'm not sure what I'm missing. development.rb Rails.application.configure do config.cache_classes = false config.eager_load = false config.consider_all_requests_local = true config.action_controller.perform_caching = false config.action_mailer.raise_delivery_errors = true config.action_mailer.perform_deliveries = true host = 'development.local' config.action_mailer.default_url_options = { host: host, protocol: 'https' } config.action_mailer.delivery_method = :smtp config.action_mailer.asset_host = 'https://development.local' config.action_mailer.smtp_settings = { address: "smtp.gmail.com", port: 587, domain: "gmail.com", user_name: ENV["GMAIL_USER"], password: ENV["GMAIL_PASS"], authentication: :plain, enable_starttls_auto: true } config.active_support.deprecation = :log config.active_record.migration_error = :page_load config.assets.debug = true config.assets.digest = true config.assets.raise_runtime_errors = true config.web_console.whitelisted_ips = '172.17.0.0/16' config.web_console.whitelisted_ips = '0.0.0.0/0.0.0.0' end

| How can I set browser caching on just .png files in rails 4 Posted: 07 Oct 2016 08:25 PM PDT Most of the content on my side isn't static but the images are (and there are a lot of images). I want to enable browser caching on .png files to make googles page speed test happier. Looking into it I see I can use something like config.static_cache_control = "public, max-age=2419200" in the production.rb file. But this caches everything including html. I just want .png files cached. In htaccess files you just add the following to cache just .png files `<filesMatch ".(png)$"> Header set Cache-Control "max-age=2419200, public" </filesMatch>`
But for rails I'm not sure what to do. |

| Change redmine routes Posted: 07 Oct 2016 07:53 PM PDT www.redmine.org We use Redmine for asset tracking and I would like to update the URLs. Presently the URLs revolve around issues and does not look right for assets. I would like to update it so that I would navigate to: www.domain.com/assets instead of www.domain.com/issues Using: Route alias in Rails I have looked at routes.rb and changed the line: resources :issues do
to resources :issues, :path => :assets do
Unfortunately it doesn't work... |

| Uploaded video can only display on my website Posted: 08 Oct 2016 06:25 AM PDT I wish to upload video to some video websites (need to be viewable in China, therefore EXCLUDE Youtube.com) and have it displayed only on my website. User cannot use the link to display it directly or embed it on their website. Is such function available for any video uploading website, and how should I achieve this purpose? |
| having problems with the login link using Spree Posted: 07 Oct 2016 05:58 PM PDT So I tried to add the login link on my Spree Rails app by following the documentation in http://guides.spreecommerce.org/developer/authentication.html However I haven't been able to get the link on my app. I created app/overrides/auth_login_bar.rb file following the documentation adding the following code to the file. Deface::Override.new(:virtual_path => "spree/shared/_nav_bar", :name => "auth_shared_login_bar", :insert_before => "li#search-bar", :partial => "spree/shared/login_bar", :disabled => false, :original => 'eb3fa668cd98b6a1c75c36420ef1b238a1fc55ad')
I also updated config/routes.rb file: Rails.application.routes.draw do # This line mounts Spree's routes at the root of your application. # This means, any requests to URLs such as /products, will go to Spree::ProductsController. # If you would like to change where this engine is mounted, simply change the :at option to something different. # # We ask that you don't use the :as option here, as Spree relies on it being the default of "spree" mount Spree::Core::Engine, at: '/' # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html devise_scope :person do get '/login', :to => "devise/sessions#new" get '/signup', :to => "devise/registrations#new" delete '/logout', :to => "devise/sessions#destroy" end end
I don't seem to find how to fix it. |
| Rails 5 - getting started with React.js Posted: 07 Oct 2016 06:33 PM PDT I'm trying to learn how to use react.js in my Rails 5 app. I have installed react-rails gem. I have used the generator to create my first component as follows: rails generate react:component AppRole title:string display_name:string category:integer --es6
That gave me a file in app/javascripts/components called app_role.es6.jsx which has: class AppRole extends React.Component { render () { return ( <div> <div>Title: {this.props.title}</div> <div>Display Name: {this.props.displayName}</div> <div>Category: {this.props.category}</div> </div> ); } } AppRole.propTypes = { title: React.PropTypes.string, displayName: React.PropTypes.string, category: React.PropTypes.node };
I watched this egghead.io getting started video (as well as having purchased Arkency's react with rails book and read this tutorial . I didn't use the air pair tutorial because I'm trying to learn es6. I got stuck using the Arkency books because there are no complete examples and I got lost in the gaps where the book assumes knowledge. However, even the getting started video from Egghead isn't working for me. I follow their structure, and try to render the index page, which has: <p><%= react_component('App_Role', title: 'hello') %></p>
A blank white page renders. When I inspect it, I can see: <div data-react-class="App_Role" data-react-props="{"title":"hello"}"></div>
When I use the chrome add-on for react, I can see the react that olark messaging plugin uses but nothing else. The egghead tutorial at least renders the 'hello' text. When I use the chrome inspector to look at the console tab, I get an error that says app role is not defined: VM4231:1 Uncaught ReferenceError: App_Role is not defined(anonymous function) @ VM4231:1getConstructor @ react_ujs_mount.self-5293119….js?body=1:58mountComponents @ react_ujs_mount.self-5293119….js?body=1:77(anonymous function) @ react_ujs_turbolinks.self-19cb50a….js?body=1:5dispatch @ jquery.self-bd7ddd3….js?body=1:5227elemData.handle @ jquery.self-bd7ddd3….js?body=1:4879t.dispatch @ turbolinks.self-c5acd7a….js?body=1:6t.Controller.r.notifyApplicationAfterPageLoad @ turbolinks.self-c5acd7a….js?body=1:6t.Controller.r.pageLoaded @ turbolinks.self-c5acd7a….js?body=1:6(anonymous function) @ turbolinks.self-c5acd7a….js?body=1:6
Can anyone see what I've done wrong? |
