| How to set up Edit for Remote Form in Rails? Posted: 24 Apr 2016 07:05 AM PDT Webpage View So in the image button above, I have a button called "Mark Item as Done". Inside that Item table, I have a date: due_date, string: task_title, text: description, and a boolean: done. Now I put the format.js in the todoitems_controller.rb because I figured that would be the best place to put it because I'm calling their edit link edit_todolist_todoitem GET /todolists/:todolist_id/todoitems/:id/edit(.:format) todoitems#edit
Now, should I also be doing something to the def edit in the todoitems_controller.rb as well or just def update? And putting remote: true in the Todolists/_form.html.erb file, is it the best place to put it there or should I put it in Todoitems/_form.html.erb file? And after doing all these, what is the next step? This is what I've managed to accomplish so far. I'm just struggling to get this started because the lectures are confusing. If there's anything else missing, I'm happy to provide more info about this! Any help would be appreciated! TODOLIST.rb - Look at button_to. That's the part I need help <body class="page"> <h1> <%= @todolist.list_name %> </h1> <h2> List due date: <%= @todolist.list_due_date %> </h2> <%= link_to 'Add Todo Item', new_todolist_todoitem_path(@todolist, @todoitem) %> <p> <% @paginate_items.each do |item| %> <div class="list"> <% if item.due_date > Date.today %> <% if item.done? %> <a class="complete"> <%= item.due_date %> </a> <a class="linkResults"> <%= link_to "#{item.task_title}", [@todolist, item], style: "font-weight: bold;" %><br/> <br/> </a> <% else %> <form class="oneLine"> <a class="notDue"> <%= item.due_date %> </a> <a class="linkResults"> <%= link_to "#{item.task_title}", [@todolist, item], style: "font-weight: bold;" %> <%= button_to "Mark Item as Done", remote: true %><br/> <br/> </a> </form> <% end %> <% elsif item.due_date == Date.today %> <% if item.done? %> <a class="complete"> <%= item.due_date %> </a> <a class="linkResults"> <%= link_to "#{item.task_title}", [@todolist, item], style: "font-weight: bold;" %><br/> <br/> </a> <% else %> <form class="oneLine"> <a class="dueToday"> <%= item.due_date %> </a> <a class="linkResults"> <%= link_to "#{item.task_title}", [@todolist, item], style: "font-weight: bold;" %> <%= button_to "Mark Item as Done", remote: true %><br/> <br/> </a> </form> <% end %> <% else %> <% if item.done? %> <a class="complete"> <%= item.due_date %> </a> <a class="linkResults"> <%= link_to "#{item.task_title}", [@todolist, item], style: "font-weight: bold;" %><br/> <br/> </a> <% else %> <form class="oneLine"> <a class="overdue"> <%= item.due_date %> </a> <a class="linkResults"> <%= link_to "#{item.task_title}", [@todolist, item], style: "font-weight: bold;" %> <%= button_to "Mark Item as Done", remote: true %><br/> <br/> </a> </form> <% end %> <% end %> </div> <% end %> </p> <br/> <p><%= will_paginate @paginate_items %></p> <%= link_to 'Delete Todo List', todolist_path, data: { confirm: "Delete this list?" }, method: :delete %> | <%= link_to 'Edit Todo List', edit_todolist_path(@todolist) %> | <%= link_to 'Back to Todo List', todolists_path %> </body>

| Live ios(swift) chat, with existing rails web application Posted: 24 Apr 2016 06:51 AM PDT I have an existing rails web application with a postgres DB running on the production server and I recently created an ios counter part. I am trying to implement a live chat message within the ios application (the web counter part does not have live chatting). I have done some research and found that I need to create something called a TCPServer to have a constant communication between the ios application and my rails application. I used daemon to run a simple ruby script on my production server (beside my web application) to test the TCPServer and I was able to run a simple ruby client to connect to the ruby TCPServer and get some static messages. I have no idea where to go from here. All examples of live ios chatting seem to be writing and receiving data to servers such as firebase. I do not want to do this because I already have a rails application communicating with a postgres database. How can I get a live chat running on the ios counter part and have both the ios and the web rails communicating to the same database? |
| Rails: calculate stats and group by day Posted: 24 Apr 2016 06:31 AM PDT I am calculating statistics for my LaserSheet model to build a morris.js chart for a dashboard page. I currently have it working with one statistic: # Show four Mondays ago up to this coming Sunday (4 weeks) start_date = Time.zone.now.beginning_of_week - 3.weeks end_date = Time.zone.now.end_of_week # Calculate sheets cut per day empty_dates_hash = Hash[(start_date.to_date..end_date.to_date).collect { |v| [v, 0] }] recent_cut_stats = LaserSheet.where('cut_at IS NOT NULL') .where('cut_at > ?', start_date.beginning_of_day) .where('cut_at < ?', end_date.end_of_day) .group("DATE(cut_at::TIMESTAMPTZ AT TIME ZONE '#{Time.zone.now.formatted_offset}'::INTERVAL)") .count recent_cut_stats = empty_dates_hash.merge(recent_cut_stats)
I would like to add a historical "sheets left to cut" stat grouped by day. To accomplish this, I need to find all LaserSheets for each day that were created_at on or before that date, where cut_at is either NULL or later than that date. I can manually do this for yesterday: LaserSheet.where('created_at < ?', Time.zone.yesterday.end_of_day) .where('cut_at IS NULL OR cut_at > ?', Time.zone.yesterday.end_of_day) .count
and for today: LaserSheet.where('created_at < ?', Time.zone.today.end_of_day) .where('cut_at IS NULL OR cut_at > ?', Time.zone.today.end_of_day) .count
I could repeat this for each day in [start_date..end_date] but this is quite inefficient. Is there a way to accomplish this with one database query? It doesn't seem as trivial as simply grouping by day. I am using PostgreSQL and Rails 4. |

| Ruby on Rails 4 - FriendlyID ID's based on users? Posted: 24 Apr 2016 06:56 AM PDT Is it possible to separate IDs on a per user basis? For example; I set up devise for users and friendly ID for nice slugs rather than 1, 2, 3 etc. However, if two users make a todo with the same name, then it's still counted as a duplicate even if that user has never made a todo with that slug before? I would like the slugs to be unique to each individual user as oppose to unique to the database. I'm pretty sure this is all the friendly ID code in my application class Todo < ActiveRecord::Base belongs_to :user extend FriendlyId friendly_id :title, use: [:slugged, :history] end
Any help is greatly appreciated. |
| Javascript not executing after Rails redirect Posted: 24 Apr 2016 05:55 AM PDT My application contains a very simple login and two separate AJAX calls. I have a loading spinner that is hidden automatically whenever a page is ready it is contained in index.js $(function() { $("loading").hide(); $("#scan_button").on("ajax:success", function(e, data, status, xhr) { $("#standard_results").hide(); $("#results").show(); $("#results").html(data); }); $(document).ajaxStop(function() { $("#loading").hide(); }); $(document).ajaxStart(function() { $('#loading').show(); }); });
When a user logs in the following happens class SessionController < ApplicationController def create user = User.find_by(username: params[:session][:username]) if(user.password == params[:session][:password]) log_in user redirect_to root_path end end def destroy logout redirect_to root_path end end
The route path takes me back to 'home#index' for which the index.js file exists. When the user logs in the redirect happens and the loading spinner is hidden and all JavaScript executes as expected. When the user hits log out however the redirect occurs, but the loading spinner is shown and no JavaScript ever gets executed. Here is my index.html.erb file that contains the JavaScript. <% content_for :title, "Network Monitor" %> <div class="container-fluid"> <nav class="navbar narvbar-dark bg-inverse"> <span class="navbar-brand">Network Monitor</span> <%= link_to "Scan", scan_path, remote: true, class: "btn btn-secondary", id: "scan_button" %> <% if logged_in? %> <span class="pull-xs-right"><%= link_to "Logout", logout_path, class: "btn btn-secondary" %></span> <% else %> <%= form_for(:session, url: login_path, :html => {:class => 'form-inline pull-xs-right'}) do |f| %> <%= f.text_field :username, class: 'form-control', placeholder: "Username" %> <%= f.password_field :password, class: 'form-control', placeholder: "Password" %> <%= f.submit "Log in", class: 'btn btn-primary', id: 'login_button' %> <% end %> <% end %> </nav> <div id="loading"> <%= image_tag "loading.gif", class: "loading_gif" %> </div> <div class="row"> <div class="col-md-12"> <div id="scan_bar"> <h3>Welcome to your network monitor!</h3> <br /> <p>To get started hit the scan button in the top right corner, this will detect the computers that are alive on your network and show them below.</p> </div> </div> </div> <div class="row"> <div id="results"> </div> <div id="standard_results"> </div>

| Rails get result from acts as taggable on by match degree? Posted: 24 Apr 2016 04:40 AM PDT I use gem acts-as-taggable-on, to add association between Articles and tags, I try three way in document: Article.tagged_with(some.tag_list, :match_all => true) return all matches articles from given tags Article.tagged_with(some.tag_list, :wild => true) return all matches articles from given tags(if articles have more tags than given, but include all given tags, will be return too.) Article.tagged_with(some.tag_list, :any => true) return any matches articles from given tags but three methods not match what I want, I want something like this: 1.given 3 tags(A,B,C) 2.return articles order by match degree, first part is match all(A,B,C), then (A,B), then (A,C), then (B,C), then (A),...and so on. in document, seems that I can only use match_all method and merge the result, does any better way to accomplish this? |
| Limit Elasticsearch results to one particular sub-class or all of them Posted: 24 Apr 2016 04:45 AM PDT I have followed this guy's tutorial to setup Elasticsearch on Rails with Mongoid. My modelisation goes like this class Generic include Mongoid::Document include Searchable index_name "generic-#{Rails.env}" end class Foo < Generic index_name "generic-#{Rails.env}" document_type "foo" end class Bar < Generic index_name "generic-#{Rails.env}" document_type "bar" end
I am importing the Foo and Bar models in the index of my Generic model. The advantage is then that I can use all the features from Generic.search(q).records, since it is a Mongoid::Criteria and my codebase currently only works with instanciated models. How can I limit the results to either Foo or Bar classes or both ? I need something like if @query.wants_only_foo? Professional.search(@q).only_foo else Professional.search(@q) end
Note : a second approach would have been to maintain separate indexes on both Foo and Bar, and use Elasticsearch::Model.search(@query, [Foo, Bar]) but then it becomes much harder to use the search results (I would have to rewrite some code to work with response.results, rather than response.records). I know this ideally the best way to go, but right now it would mean extra work so I need a faster solution. |

| Strange behaviour about rendered file's size Posted: 24 Apr 2016 05:59 AM PDT In controller, I have something like this: respond_to do |format| format.ini do response.headers['Content-Disposition'] = "attachment; filename=somefile.ini" render ini: SomeClass.make_ini(data) end end
SomeClass.make_ini(data) renders the correct ini file (1.5MB) for API users. There is a task from our clients to add Content-Length header. The reason doesn't matter.
When I try: respond_to do |format| format.ini do file = SomeClass.make_ini(data) response.headers['Content-Length'] = file.size.to_s response.headers['Content-Disposition'] = "attachment; filename=somefile.ini" render ini: file end end
file.size.to_s brings 1301761. And after setting Content-Length, the rendered file is 1.2MB. And content is cut.
I would be grateful if someone could tell the reason. |
| CSS dropdown menu using W3schools example Posted: 24 Apr 2016 03:32 AM PDT I'm attempting to create a dropdown menu using W3schools example method, but I can't seem to get the menu to stay open when moving the cursor away from the button. At first I thought my code was wrong, so I directly copied the W3schools code to my files, but still got the same result. CSS code: .personal-dropbtn { border: none; cursor: pointer; } .personal-dropdown { position: relative; display: inline-block; } .personal-dropdown-content { background: #DDD; display: none; position: absolute; right: 0; } .personal-dropdown-content a { display: block; } .personal-dropdown-content a:hover { } .personal-dropdown:hover .personal-dropdown-content { display: block; }

As you can see, I'm utilizing Ruby on Rails to create the website. I'm wondering if that might be breaking the menu in some way? I plugged my code without the Ruby incjection into JSfiddle and it worked there, so I can only conclude that Rails might be disturbing somehow? |

| Pundit Policy issue, correct wikis not show Posted: 24 Apr 2016 01:25 AM PDT I want different types of wikis to appear on the index view depending on the role of the user. The policy for admin and standard / guest users work as it should but when it comes to premium users and collaborations it gets a little messy.In my app i have the ability to add Collaborators to private Wikis . So when im logged in as a premium user i get my private wikis and non private wikis but not any wikis where i am a collaborator of. Could it have to do with my Policy or my model associations . wiki#index def index @wikis = Kaminari.paginate_array(policy_scope(Wiki)).page(params[:page]).per(10) end
user model class User < ActiveRecord::Base has_many :wikis has_many :collaborators belongs_to :collaborators ....
Wiki model class Wiki < ActiveRecord::Base belongs_to :user has_many :collaborators has_many :users, through: :collaborators ....
collaborator model class Collaborator < ActiveRecord::Base belongs_to :user belongs_to :wiki end
Wiki_policy class Scope attr_reader :user, :scope def initialize(user, scope) @user = user @scope = scope end def resolve wikis = [] if user.role == 'admin' wikis = scope.all # if the user is an admin, show them all the wikis elsif user.role == 'premium' all_wikis = scope.all all_wikis.each do |wiki| if wiki.private == false || wiki.owner == user || wiki.collaborators.include?(user) wikis << wiki # if the user is premium, only show them public wikis, or that private wikis they created, or private wikis they are a collaborator on end end else # this is the lowly standard user all_wikis = scope.all wikis = [] all_wikis.each do |wiki| if wiki.private == false || wiki.collaborators.include?(user) wikis << wiki # only show standard users public wikis and private wikis they are a collaborator on end end end wikis # return the wikis array we've built up end end

| Nested Resources in Rails 4 Posted: 24 Apr 2016 12:36 AM PDT Im attempting to create a Rails app that manages temperatures for a garden. I have setup my controllers and models appropriately to have resources for Grow - Tray - Plant. Grow has many trays Tray has many Plants Im able to create nested trays in each grow. But I am not able to create plants in a designated tray. The github repo Im getting the following error: undefined method `tray' This is for my plant _form <%= form_for([@grow, @grow.tray.plants.build]) do |f| %> <div class="field"> <%= f.label :title %><br> <%= f.text_field :title %> </div> <div class="field"> <%= f.label :description %><br> <%= f.text_area :description %> </div> <div class="field"> <%= f.label :tray_id %><br> <%= f.text_field :tray_id %> </div> <div class="actions"> <%= f.submit %> </div> <% end %>
The routes look as such: resources :grows do resources :trays do resources :plants end end
The form for building the tray looks like this and it works: <%= form_for([@grow, @grow.trays.build]) do |f| %> <div class="field"> <%= f.label :title %><br> <%= f.text_field :title %> </div> <div class="field"> <%= f.label :description %><br> <%= f.text_area :description %> </div> <div class="field"> <%= f.label :grow_id %><br> <%= f.text_field :grow_id %> </div> <div class="actions"> <%= f.submit %> </div> <% end %>
Is this even the right approach? |
| "Data has contents that are not what they are reported to be" - Paperclip with CKEditor Posted: 23 Apr 2016 11:28 PM PDT I am getting a following error when uploading an image with CKEditor + Paperclip on Rails. "Data has contents that are not what they are reported to be". What I have done so far: - Installed ImageMagick and set the PATH and
development.rb with Paperclip.options[:command_path] = 'C:\Program Files (x86)\ImageMagick-6.9.3-Q16' - Tried removing all the validations and styles in model file
- Installed the
file.exe and set the PATH - Tried changing
Paperclip.options[:command_path] = 'C:\Program Files (x86)\GnuWin32\bin'in development.rb file which will give me Paperclip::NotIdentifiedByImageMagick error
Update Changing a validations in model requires an server restart, apparently. I changed validates_attachment_content_type in ckeditor\picture.rb to validates_attachment_content_type :image, :content_type => ["image/jpg", "image/jpeg", "image/png", "image/gif"] which eliminates the error but gives me this: transformed to long black image |
| Shoppe category routing Posted: 23 Apr 2016 11:02 PM PDT I'm stuck with a little problem with displaying Shoppe categories. I want the category name and image displayed on my index page, category name acts as a link to the category page, where products of this category are displayed. I have the following code in my view: <% @products.each do |category, products| %> <%= link_to category.name, product_category_path %> <% end %>
but it returns me an error undefined local variable or method 'product_category_path' for #<#<Class:0xb22076fc>:0xb2205870> should I make a controller for categories, as well as for products? Because now I have only products_controller.rb with the following code: class ProductsController < ApplicationController def index @products = Shoppe::Product.root.ordered.includes(:product_categories, :variants) @products = @products.group_by(&:product_category) end def show @product = Shoppe::Product.root.find_by_permalink(params[:permalink]) end end

| Rails Wicegrid checkbox filter Posted: 23 Apr 2016 10:39 PM PDT I'm using wice grid in my application. I have a model which is having a highlight attribute with boolean values. In wice grid table, I do not want to use the default dropdown filter, instead use some checkbox or toggle button. <%= grid(event_grid) do |g| g.column name: 'Highlight', attribute: 'highlight' do |event| event.highlight end end -%>
By default, the filter is dropdown with true and false values. I want to have a checkbox filter instead of dropdown. Let me know if you need any more details... Thanks |
