| How to restrict order creation Posted: 27 Jun 2016 08:11 AM PDT So in my rails app I have store with products, order_items, orders, user, cart... Right now, orders are being created and saved in database upon new session for a user. So if user adds 1 order_item to his order, logs out, comes back again and ads a new order_item, new order is being created in database. The old order for that 1 order_item still exist in database however it's not being showed for a current_user on the frontend, because new order is created. What I want to achieve is that there should be only one order per 30 days per user. So even if user adds some order_items, logs out, come back again, to have that existing order associated with that user as well on the frontend. And it should be like that for 30 days... Counter for new order should start upon addition of the first order_item. To sum up: So I want not to create new orders upon new session for current_user, instead to show the order that has be created from previous session and keep it like that for 30 days... How can I achieve this? class OrderItemsController < ApplicationController def create now = Date.today if current_user.begin_date && ((now - 30) < current_user.begin_date) if current_user.order_counter >= 3 redirect_to root_path else current_user.order_counter += 1 current_user.save end else current_user.order_counter = 1 current_user.begin_date = now current_user.save end @order = current_order @order_item = @order.order_items.new(order_item_params) @order.user_id = current_user.id @order.save session[:order_id] = @order.id respond_to do |format| format.js { flash[:notice] = "ORDER HAS BEEN CREATED." } end end private def order_item_params params.require(:order_item).permit(:quantity, :product_id, :user_id) end end

| Bundler is using a binstub that was created for a different gem - in the context of a Rails engine Posted: 27 Jun 2016 08:03 AM PDT I have created a simple Rails engine, using Rails v4.2.6. Now it ran into problems related to the "binstub management": When I invoke the rails binary/binstub, e.g. via rails -v or when I navigate to the dummy application within spec/dummy and I want to start a rails console, I get the following warning: Bundler is using a binstub that was created for a different gem. This is deprecated, in future versions you may need to `bundle binstub my-sample-engine` to work around a system/bundle conflict.
And if I use my engine within another Rails application, this error message is propagated to the hosting application - I get the same message when starting a rails console session there. The warning remains even when I invoke the console via bundle exec rails c. I found some suggestions in the answers of this Stackoverflow discussion but unfortunately the suggestions did not resolve the problem in my situation. What I have tried so far: Deleting the "top-level binstub" located in bin/. There ony was a single binstub for rails. But, no success. If I run "rails -v" afterwards the warning appears again Deleting/re-creating the binstubs within the dummy application via rm -rf bin/ && rake rails:update:bin was not successful, too. Configuring bundler to turn off its binstub generator by bundle config --delete bin and repeating 1 and 2 did not help, too. What went wrong in my case? How can I fix the "wrong" binstub situation? Hopefully useful trivia: I'm using bundler version 1.11.2, rails version 4.2.6 and as stated above, everything happens within a mountable engine. |

| Ruby-on-Rails: Can enum value be a string. Where is this documented? Posted: 27 Jun 2016 07:49 AM PDT Can someone point me to some ROR documentation that describes setting the value of an enum as a string? All the documentation and examples I've found seem to indicate that the value should be an integer. However I am able to create an enum with string values, use it in view and save it to the database without any issues. I would really like to find out more on this topic. Example that works Set in ModelName enum category_enum: { 'abc efg'=> 'alpha', 'hot dog' => 'bun' }
Set in view <%= f.select :category, ModelName.category_enums %>

| How to add and remove a class to hide and show a table row? Posted: 27 Jun 2016 07:46 AM PDT In my current situation in my Ruby on Rails application, I am trying to make a drop-down function on each table tow to show advanced details for a server that comes from a database. My through process is to make the hidden row default to display: none; then add a viewing class when it is clicked to view it, then hide it when it is clicked again. Here is my javascript: var hideDetails, showDetails; showDetails = function() { $(this).closest('tbody').addClass('viewing'); return false; }; hideDetails = function() { $(this).closest('tbody').removeClass('viewing'); return false; }; $table.on('click', 'tbody.viewing', hideDetails); $table.on('click', '.details-link', showDetails);
Then my css: table.collapsible { // css for drop-down #hiddenRow.details { display: none; tbody.viewing { #hiddenRow.details { display: table-row; } } } }
Lastly, my HTML code: <table id="servertable" class="paginated table collapsible table-hover sortable" data-sort-name="name" data-sort-order="desc"> <tr style="background-color: #cccccc"> <th><%= sortable "pod_id" %></th> <th><%= sortable "ip"%></th> <th><%= sortable "status"%></th> <th><%= sortable "datacenter"%></th> <th><%= sortable "memory_used"%></th> <th></th> </tr> <!--A for loop to iterate through the database and put it into the table--> <tbody> <% @servers.each_with_index do |server| %> <tr> <td><%= server.pod_id %></td> <td><%= server.ip %></td> <td><%= server.status %></td> <td><%= server.datacenter %></td> <td><%= (server.memory_used * 100).floor %>%</td> <td><input type="button" onclick="showDetails(); hideDetails();"></input></td> <tr id="hiddenRow"> <td colspan="6">Information</td> </tr> </tr> <% end %> </tbody> </table>
My problem is that even though in my css, I have the default display of the hidden row to be none, it is still showing up on the screen. As well as the button not functioning as well. Some help would be appreciated. Note: There is some extra stuff in my HTML code because I have some other functions for my table such us sortable columns, just ignore that, it doesn't have to do with my question. |
| Having a Ruby on Rails Selector without a form Posted: 27 Jun 2016 07:42 AM PDT I have a schools' program table set up, and want a user to be able to add a new program to a school.

| Multiple urls with Paperclip Posted: 27 Jun 2016 06:59 AM PDT Is it possible to upload multiple files with Paperclip? I've tried my best by going through their docs but noting useful. I want to submit an array value to a rails 5 controller using react. My state has an array, let's say [a, b, c]. In my render, I have: <form> <!-- I have an input file button for the upload visible --> <input type="hidden" name="user[image][]" value={this.state.files} /> </form>
To make this example slimmer, I only show the hidden field where the value is. The submitted params looks "encrypted" but I'm confident I see the array. My controller: # :image is not permitted params[:user][:image].each do |image | User.find(1).update_attributes(user_params.merge({image: image})) end
Only the first image in the array is being saved. Does paperclip supports multiple? The aim is: User.find(1).image.url, then I'd see an array of urls. I'm using PostgreSQL as the db so not sure if I should make the table column an array but do paperclip supports that? |

It also says that I must provide the password that I set when installing msql. I set the password in database.yml file as "boots" username: root password: boots host: localhost But I still get the same error. My problem is that I am not sure now if this is the correct password I set to begin with. What I want to know is how to retrieve that original password I set o how to set a new one. Thanks! 
PS: I've just opened up mysql command line client and the first thing it ask for is a password to allow access. I Typed "boots" and it did allow access to the mysql command line client. So the problem I have is NOT the pássword. :( Any Ideas on how to debug anybody? |

| Apache configuration to access files from outside of ruby Posted: 27 Jun 2016 05:32 AM PDT My server configuration is as follows: Server running apache2 Passenger is providing ruby application I have an images folder which is outside the ruby app
The ruby application has the following path: /home/myuser/domains/domainname/rubyapp
The images folder lies at /home/myuser/images
I added a Location and an Alias into my apache2 configuration <Location /home/myuser/images> PassengerEnabled off allow from all Require all granted Options -Indexes +IncludesNOEXEC +SymLinksIfOwnerMatch +ExecCGI </Location> Alias /images /home/myuser/images
I start the ruby application with: passenger start -p 3001 -d -e production
Inside the images folder there is an image file asd.jpg - which i cannot display, because i get a ruby 404 error message. I want to access the image with www.mydomain.com/images/asd.jpg What am i doing wrong? Which configuration has to be edited (and how)? |

| Getting id errors when trying to delete tags Posted: 27 Jun 2016 05:34 AM PDT I am extremely new to ruby on rails and I was following a tutorial to set up a simple blog style website. I had implemented tags on the articles but now I'm getting errors when trying to implement the deleting of tags. I think this is where the error is coming from. def destroy @tag = Tag.find(params[:id]) @tag.destroy flash.notice = "Tag '#{@tag.name}' Deleted!" redirect_to action: "index" end
I think it's the line @tag = Tag.find(params[:id]) that's causing the following error: Couldn't find Tag with 'id'=#< Tag::ActiveRecord_Relation:0x007fdd2c016ba0> I'm stuck with this because I managed to implement the deleting of articles in this way so I'm unsure as to why this won't work. Edit: This is the view file. <h1>All Tags</h1> <ul id="tags"> <% @tag.each do |tag| %> <li> <%= link_to tag.name, tag_path(tag) %> <%= link_to "delete", tag_path(@tag), method: :delete, data: {confirm: "Really delete the tag?"} %> </li> <% end %> </ul>

| Rails: Update data via link_to (without view) Posted: 27 Jun 2016 06:19 AM PDT I'd like to update the data without form. Although there are similar questions, they don't work for me. Update field through link_to in Rails link_to update (without form) What I'd like to do is to delete data as followings; For example, delete name and address when delete link is clicked. id | name | address | ... 12 | aaa | bbb | ...
to id | name | address | ... 12 | | | ...
Although I tried some, error was displayed.(such as ActionController::RoutingError) schema create_table "rooms", force: :cascade do |t| t.string "name" t.text "address" ...
model schedule.rb class Schedule < ActiveRecord::Base belongs_to :user has_many :rooms, inverse_of: :schedule, dependent: :destroy accepts_nested_attributes_for :rooms, allow_destroy: true ...
room.rb class Room < ActiveRecord::Base belongs_to :schedule, inverse_of: :rooms default_scope -> { order(day: :asc) } ...
view I'd like to add the link in schedules/_schedule.html.erb It has the followings; ... <% schedule.rooms.each do |room| %> ... <% if room.name.present? %> <%= link_to "Delete", rooms_path(room, room:{address: nil}) , method: :put, data: { confirm: "You sure?"} %> ...
I also tried another code as below, but they don't work. <%= link_to "Delete", rooms_path(room:{address: nil}) , method: :put, data: { confirm: "You sure?"} %> <%= link_to "Delete", rooms_path(room) , method: :put, params: {address: nil}, data: { confirm: "You sure?"} %>
and so on. routes.rb ... resources :schedules do resources :events end resources :schedules do resources :rooms end resources :rooms do resources :events end ...
It would be appreciated if you could give me any suggestion. |

| Adding a counter to controller. Rails 4 Posted: 27 Jun 2016 05:33 AM PDT I have a rails 4 app. In the controller, I iterate through each assignment entry in the database to check if a requirement is associated with more than one assignment. However, I can't figure out how to add a counter, i.e. hit = 0, hit = 1, etc. to the controller. EDIT: The relationship between assignment and requirement is HABTM. My code is below: def check_requirements @assignments = Assignment.all @assignment = Assignment.find(params[:id]) @requirement = Requirement.find(params[:requirement_id]) @assignments.each do |assignment| if assignment.include(requirement) #here's where the counter should go end end if counter is greater than zero or one, do nothing else @assignment.delete(requirement) end
