| Create action not being called in form Posted: 19 Mar 2016 06:55 AM PDT I've just started a new app where I want to take a postcode in a form and save it to the database. My problem is that the create action doesn't seem to be being called no matter what I try. Routes: root 'postcodes#new' resources :postcodes, only: [:new ,:create]
Controller: postcodes_controller.rb class PostcodesController < ApplicationController def new @postcode = Postcode.new end def create @postcode = Postcode.new(postcode_params) if @postcode.save flash[:success] = 'Success' else flash[:error] = 'Error' end end private def postcode_params params.require(:postcode).permit(:code) end end
Model: postcode.rb class Postcode < ApplicationRecord validates :code, presence: true, uniqueness: true end
View: postcodes/new.haml .container %form %fieldset.form-group = form_for @postcode do |f| = f.label :postcode = f.text_field :code, placeholder: 'Example Postcode', class: 'form-control' = f.submit 'Submit', class: 'btn btn-primary'
I've attempted to pass more options in the form_for such as the method and action and now I have a feeling it's a routing error. Any help will be appreciated. Thanks. |
| MySQL REGEXP using Rails ActiveRecord Posted: 19 Mar 2016 06:53 AM PDT This has been bugging me for a while now... I need to query a table of users and find those that have a double space in the name. I have multiple versions of SQL queries that work directly against the db, the simplest and more succinct being: SELECT 'first last' REGEXP '[[:space:]]{2}';
I can also make it work from rails using ruby REGEX: User.pluck(:full_name).select {|n| n =~ /([[:alpha:]]*)[[:space:]]{2}/ }
OR User.pluck(:full_name).select {|n| n =~ /\w+\s{2}/ }
I have been trying to use AR where in several ways, but I am not sure what I am missing. Maybe I need to escape something... I read a few times: http://dev.mysql.com/doc/refman/5.0/en/regexp.html I just don't see why it doesn't work 2] pry(main)> User.where("'full_name' REGEXP ?", "[[:alpha:]]*[[:space:]]{2}").count => 0 [3] pry(main)> User.where("'full_name' REGEXP ?", '[[:alpha:]]*[[:space:]]{2}').count => 0 [4] pry(main)> User.where("'full_name' REGEXP ?", '[[:alpha:]]*[[:space:]]{2}').to_sql => "SELECT `users`.* FROM `users` WHERE ('full_name' REGEXP '[[:alpha:]]*[[:space:]]{2}')" [5] pry(main)> User.where("'full_name' REGEXP ?", '[[:space:]]{2}') => [] [6] pry(main)> User.where("'full_name' REGEXP ?", '[[:blank:]]{2}') => [] [7] pry(main)> User.where("'full_name' RLIKE ?", '[[:blank:]]{2}') => [] [8] pry(main)> User.where("'full_name' RLIKE ?", '[[:blank:]]{2}').to_sql => "SELECT `users`.* FROM `users` WHERE ('full_name' RLIKE '[[:blank:]]{2}')" [9] pry(main)> User.where("'full_name' RLIKE ?", '[[:blank:]]').count => 0 [10] pry(main)> User.where("'full_name' RLIKE ?", '[[:space:]]').count => 0 [11] pry(main)> User.where("'full_name' RLIKE ?", '.*[[:space:]].*').count => 0 [12] pry(main)> User.where("'full_name' RLIKE ?", '\[[:space:]\]').count => 0

| How to ensure Capistrano installs local gems on production Posted: 19 Mar 2016 06:53 AM PDT After running a successful cap production deploy, my app isn't getting the gems installed by Capistrano in the right location. I would expect the gems to be installed here: /home/user/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/
But instead, they're being installed here: /home/y/app/shared/bundle/ruby/2.3.0/gems/
Furthermore, when running the command gem list, listing local gems, the results is very small (considering it should list more like 30 gems): *** LOCAL GEMS *** bigdecimal (1.2.8) bundler (1.11.2) io-console (0.4.5) json (1.8.3) psych (2.0.17) rdoc (4.2.1)
I realize this information is very little considering - let me know if there's any other information I can provide. |
| Restrict access in Rails app only for users logged in Posted: 19 Mar 2016 07:00 AM PDT I'm learning Rails and I'm trying to restrict access to pages if a user hasn't logged in and to only allow them to view the login and sign up pages. Currently, my code creates a session when a user logs in and clears it when the user logs out. I've got a Sessions helper so that I can check whether a user is logged in but I'm unsure how to redirect the user throughout the app if he/she's not logged in. CODE: /controllers/application_controller.rb class ApplicationController < ActionController::Base protect_from_forgery with: :exception include SessionsHelper end
/controllers/sessions_controller.rb class SessionsController < ApplicationController def new end def create user = User.find_by(email: params[:session][:email].downcase) if user && user.authenticate(params[:session][:password]) log_in user redirect_to user else flash.now[:danger] = 'Invalid email/password combination' render 'new' end end def destroy log_out redirect_to root_url end end
/helpers/sessions_helper.rb module SessionsHelper # Logs in the given user. def log_in(user) session[:user_id] = user.id end # Returns the current logged-in user (if any). def current_user @current_user ||= User.find_by(id: session[:user_id]) end # Returns true if the user is logged in, false otherwise. def logged_in? !current_user.nil? end # Logs out the current user. def log_out session.delete(:user_id) @current_user = nil end end

| Display checkbox instead of drop down select Posted: 19 Mar 2016 06:42 AM PDT I have the following form: <%= form_for @user do |f| %> <div class="form-group"> <%= f.label :extra_act %> <%= f.select(:extra_act, [['Act 1', 1],['Act 2', 2], ['Act 3', 3]], class: 'form-control', required: true) %></br> </div> <%= f.submit 'Submit', class: 'btn btn-primary' %> <% end %>
Is there a way to offer checkboxes instead of the drop down select menu here? I have found checkboxes on the ruby website, but I only want users to have the option of selecting one checkbox. |
| How to parse variously formatted or natural language dates locally and pass to jquery datepicker? Posted: 19 Mar 2016 05:44 AM PDT I have a :date_as_text field in a Rails form. When the form is submitted this field is parsed by Chronic and a datetime saved to the database. As this is a text field, the user can type a variety of different date formats, or even 'today', 'yesterday', etc and all (most) are interpreted by Chronic. Input values can also be set via a jquery datepicker attached to the field. If the user types an entry that corresponds exactly to the date format expected by datepicker (in this case yy-MM-dd), then the datepicker is updated to display the currently selected data. How can I parse the entered value on the client side so that the datepicker will also recognize other date formats? I'm struggling to conceptualize how to even approach this. - How to parse variously formatted or natural language dates locally? One approach seems to be https://github.com/datejs/Datejs, though this library does not appear to be well maintained.
- When to parse? x seconds after the last entry in the field? Or is there a better way?
- How to pass the parsed value into datepicker? Would the datepicker need to be reinitialized?
Does this sound feasible, or is a Really Bad Idea? Appreciate thoughts or experience from others. |

| how to create users_controller.rb with devise? Posted: 19 Mar 2016 04:37 AM PDT I used gem: devise to create models/user.rb by running rails g devise User, and I used devise to create views by running rails g devise:views. Now I want to create controllers/users_controller.rb. How can I do that? rails g controller users
Is this correct? And is this user connected with devise User? I looked at another app, and class UsersController < ApplicationController works there. I am new. Thanks for answering. |
| Unexpected trouble comparing numbers Posted: 19 Mar 2016 06:17 AM PDT I'm writing a helper method that adds a class to an element depending on whether two numbers are equal to eachother. My code is as follows: <% for note in @company.convertible_notes.each %> <% if note.id %> <li class="tab <%= note_nav(params, note.id) %>"><%= link_to "#{note.security_series} #{note.security_class} Note", convertible_note_convertible_notees_path(note) %></li> <% end %> <% end %>
note_nav calls the following helper: def note_nav(params, note) "active" if params[:controller]=="convertible_notees" && note.to_s==params[:converible_note_id].to_s end
Now the surprising thing is that I cannot get the expression note.to_s==params[:converible_note_id].to_s to register true. Even when I know the two numbers being compared are both "1". I checked it using my log: logger.debug "are they equal? #{note.to_s==params[:converible_note_id].to_s} note.id is #{note} note params are #{params[:convertible_note_id]}"
Which yields the following log entry: are they equal? false note.id is 1 note params are 1 I would guess that they're two different types but given that I've converted both of them to_s, I don't know how that would be an issue. I've used this exact same technique on a few combinations of other models and have been completely error free. Any idea as to what might be going on? Thanks in advance |
| How to print the Model.create calls made by FactoryGirl.create? Posted: 19 Mar 2016 05:08 AM PDT Is there any way to print the ActiveRecord operations called by FactoryGirl.create? Say we have a factory :foo of model Foo. Running FactoryGirl.create(:foo), creates a database entry for the model Foo and some other entries for different models, say Bar, Car, etc. Is there any way in which we could convert this FactoryGirl.create(:foo) command into its underlying Model.create commands? For example FactoryGirl.create(:foo)
should break into Foo.create(name: 'some name', ...) Bar.create(field_value: 'asdf', ....) Car.create(field_value: 'asdf1231', ....) ...

| Bootstrap navigation tabs with rails subpages Posted: 19 Mar 2016 03:08 AM PDT I'm attempting to style a rails app with bootstrap navigation tabs. My App is such that I have not only pages but subpages as well. Tabs represent superpages (so to speak). See below: <ul class="nav nav-tabs"> <li class="tab"><%= link_to "Contacts", edit_entities_path(@company) %></li> <% for stock in @company.stocks.each %> <% if stock.id %> <li class="tab"><%= link_to "#{stock.security_series} #{stock.security_class} Stock", stock_stockholders_path(stock) %></li> <% end %> <% end %> <% for option in @company.options.each %> <% if option.id %> <li class="tab"><%= link_to "#{option.security_series} #{option.security_class} Options", option_optionees_path(option) %></li> <% end %> <% end %> <% for warrant in @company.warrants.each %> <% if warrant.id %> <li class="tab"><%= link_to "#{warrant.security_series} #{warrant.security_class} Warrant", warrant_warrantees_path(warrant) %></li> <% end %> <% end %> <% for note in @company.convertible_notes.each %> <% if note.id %> <li class="tab"><%= link_to "#{note.security_series} #{note.security_class} Note", convertible_note_convertible_notees_path(note) %></li> <% end %> <% end %> </ul>
Tabs denote any number of stocks, convertible_notes, options, and warrants resources :stocks do resources :stockholders end resources :convertible_notes do resources :convertible_notees end resources :options do resources :optionees end resources :warrants do resources :warrantees end
For more context a Company has_many :stocks :convertible_notes :options :warrants What I'm after: I would like to apply the active class if I am on a given page OR if I'm on its sub-page. So, I not only want the stock with ID 1's tab to be .active if I'm on it, but also if I'm on the stockholder subpage. What might be the best way to accomplish this? Thanks in advance. |
| SQL query for Rails 4 table reading one column but not the other correctly using .where Posted: 19 Mar 2016 01:21 AM PDT I need to produce a result based on an if condition that uses the && construction. In my view, I need to do two things: 1) check to see if the current # of registered players exceeds the max specified by max_players; 2) Check and confirm that the user has not already registered. If the query matches both conditions, I will return an error. <% if Participation.where(game_id: params[:id]).count >= Game.first.max_players && Participation.where(user_id: current_user.id).exists?(false) %> <p>Sorry, it failed.</p> <% else %> <div class="button-wrap"> <br> <a class="btn rad-button2 wwt flat vertical" <%= link_to "Reserve Spot", reservation_path(id: params[:id]) %> </a> </div> <% end %>
Despite how both conditions are structured almost identically, the 2nd condition seems to be "true" (meaning, weirdly in this case, that it is false, and the current_user.id does not exist) at all times regardless of what is in the real table. Testing First thing I checked was to identify which condition was causing a problem. If I remove the 2nd condition and go to a game where the # of matching results with the same game_id in the table matches the params, it will show the error. So far, so good. However, if I use the second condition only on a game where the current_user has registered, it still defaults to the else condition. Am I sure there are results that match both conditions? Let's say I am using the URL http://localhost:3000/lobby?id=2. Ok, I want to find matching results with the id of "4." Participation id: 4, user_id: 2, game_id: 2, ranking: 0, created_at: "2016-03-19 07:20:14", updated_at: "2016-03-19 07:20:14">, Participation id: 30, user_id: 3, game_id: 2, ranking: 0, created_at: "2016-03-19 07:57:36", updated_at: "2016-03-19 07:57:36
As you can see, we have two game_id for our matching params. In my Game table, I specify that the max is 1 player for testing, so 2 > 1, and first condition passes (and the test with it alone is successful at producing error). The second condition though -- when signed in as user_id: 2 still fails to produce the error, yet it is using the same where strategy. Any idea where I am going wrong? Edit 1 - Adding Participation Migration class CreateParticipations < ActiveRecord::Migration def change create_table :participations do |t| t.references :user, index: true t.references :game, index: true t.integer :ranking, null: false, default: 0 t.timestamps end end end

| How to return the validation values for a Rails model Posted: 19 Mar 2016 01:29 AM PDT Given a model validation such as validates :my_number, numericality: { greater_than_or_equal_to: 1, less_than_or_equal_to: 300 }
How can I read and e.g. display these values in the view? MyModel.validators_on(:my_number).first.options[:on_or_before]
appears to be getting close. But this returns a file line reference, and I'm unsure how to manipulate this to return a value. #<Proc:0x007fa5a3d3eb90@/Path/To/Project/app/models/my_model.rb:128 (lambda)>
Is there a convenient way of accessing these validation values and doing something in the view like <p>This value must be between <%= @model.my_number.validation_greater_than %> and <%= @model.my_number.validation_less_than %></p>

| Load Engine Views in Host App Posted: 19 Mar 2016 12:51 AM PDT To reduce repetition I put a very simple bootstrap validation system in a gem. Along with helpers (already loading) I have 2 partials.
/app/views/notifiengine/_notfications.html.erb
/app/views/notifiengine/_validations.html.erb In the past I would just generate the views, but this time I want to let the gem hold the partial and render it without copying the views over. <%= render 'notifiengine/notifications' %>
From my understanding rails looks in the apps/views/ which I tried than I also tried app/views/notifiengine with no difference says missing template. Am I missing a step somewhere or something? |
| GitLab archive over API creating endless zips inside zips Posted: 19 Mar 2016 12:49 AM PDT I am using the GitLab API to create repository archives and when I do it creates a zip file that has a zip inside, that has a zip inside, etc. Here is the code that is making the request: def self.get_archive(project_id, branch) request = Typhoeus::Request.new( BASE_URL + "/projects/#{project_id}/repository/archive?sha=#{branch}", method: :get, params: nil, headers: { "PRIVATE-TOKEN": ADMIN_TOKEN } ) request.run response = request.response if response.success? file_name = "archive-#{SecureRandom.hex(5)}.zip" File.open(Rails.root + "public/archives/" + file_name, "wb") do |file| file.write(response.body) end return { success: true, file_path: "/archives/" + file_name } else return { success: false, response_raw: response } end end
Any thoughts as to what's gone wrong? My thinking here was to take the binary that I get back and write it to a zip file. |
| Rails Order by SQL Posted: 19 Mar 2016 01:13 AM PDT I have a TraitQuestion model that have a number of traits or answers - each of which has a value such as 1, 2, 3, or -3105 (for none of the above). I can't change these values because they are required for an external API. I'd like to order them by the value, but when I do that, the answer with -3105 shows up at the top even though it says "None of the above": Answer 4 = -3105 Answer 1 = 1 Answer 2 = 2 Answer 3 = 3
Any idea on how we could order this so that it's 1 2 3 -3105?
I'm pretty new to SQL but it seems like I should be able to do something like this: @trait_question.traits.order('CASE WHEN value AS int > 0 then 1 ELSE 0 END')
But that doesn't work. Any ideas how I can adjust the order call SQL such that it would order them in the correct order? EDIT: This is Postgresql 9.4.1 via Amazon AWS |
| Chain scopes between models in Rails Posted: 19 Mar 2016 12:54 AM PDT I'm having some trouble querying between models in Rails. I have a class Message that belongs_to: booking. My goal is to add an active scope to Message that depends on a Booking scope. class Booking < ActiveRecord::Base has_one :event has_many :messages def self.active includes(:event). where('events.endtime >= ? AND status IS NOT ?' Time.current.beginning_of_week, statuses['canceled']) end end class Message < ActiveRecord::Base belongs_to :booking belongs_to :person self.active(person_id) where(person_id: person_id).merge(Booking.active) end end
I want to find the Messages directed to a specific Person where the associated Booking is active. I therefore wish to use the Booking.active when creating Message.active. Calling Message.active(1) with above implementation returns the following error: Association named 'event' was not found on Message; perhaps you misspelled it?
Is there any way I can use Booking.active in the implementation of Message.active and get Messages returned? |

| Overriding association in ActiveModel Serializer - returns all attributes instead of serialized object attributes Posted: 19 Mar 2016 12:16 AM PDT I have 2 models : Repository and Branch, both of which have a corresponding serializer. In RepositorySerializer, I want to list one default branch. Here's how I'm doing it: attributes :id, :name, :ssh_url, :default_branch has_many :branches def default_branch object.branches.find_by_name(object.default_branch) end
In BranchSerializer, I have: attributes :id, :name
branches returns all branches properly serialized and only containing id and name attribute, but default_branch returns all the attributes of that branch.
Is there any way to utilize the existing BranchSerializer in this case or should I myself return the required attributes from the method default_branch. Any help would be appreciated. |

| stripeToken is not being returned to my form Posted: 18 Mar 2016 11:02 PM PDT I have my Stripe integration setup correctly, because it does return an error This customer has no attached payment source which is a Stripe error indicating that the form is not returning sufficient payment info. This is my subscriptions.js.coffee: stripeResponseHandler = (status, response) -> $form = $('#payment-form') if response.error #Show the errors on the form $form.find('.payment-errors').text response.error.message $form.find('button').prop 'disabled', false else # response contains id and card, which contains additional card details token = response.id #Insert the token into the form so it gets submitted to the server $form.append $('<input type="hidden" name="stripeToken" />').val(token) # and submit $form.get(0).submit() return jQuery ($) -> $('payment-form').submit (event) -> $form = $(this) $form.find('button').attr 'disabled', true Stripe.card.createToken $form, stripeResponseHandler false return
This is my form at new.html.erb: <% unless @subscription.errors.blank? %> <%= @subscription.errors.full_messages.to_sentence %> <% end %> <h2>Subcribing to <%= @plan.name %></h2> <%= form_for @subscription, html: {id: 'payment-form'} do |f| %> <input type="hidden" name="plan_id", value="<%= @plan.id %>" /> <span class="payment-errors"></span> <div class="form-row"> <label> <span>Email Address</span> <input type="email" size="20" name="email_address" /> </label> </div> <div class="form-row"> <label> <span>Card Number</span> <input type="text" size="20" data-stripe="number" /> </label> </div> <div class="form-row"> <label> <span>CVC</span> <input type="text" size="4" data-stripe="cvc" /> </label> </div> <div class="form-row"> <label> <span>Expiration (MM/YYYY)</span> <input type="text" size="2" data-stripe="exp-month" /> </label> <span> / </span> <input type="text" size="4" data-stripe="exp-year" /> </div> <button type="submit">Pay Now</button> <% end %>
This is the SubscriptionsController#Create: def create @plan = Plan.find(params[:plan_id]) @subscription = CreateSubscription.call( @plan, params[:email_address], params[:stripeToken] ) if @subscription.errors.blank? flash[:notice] = "Thank you for your purchase! Please click the link in the email we just sent you to get started." redirect_to authenticated_root_path else render :new end end
The above calls this app/services/create_subscription.rb: class CreateSubscription def self.call(plan, email_address, token) user, raw_token = CreateUser.call(email_address) subscription = Subscription.new( plan: plan, user: user ) begin stripe_sub = nil if user.stripe_customer_id.blank? binding.pry customer = Stripe::Customer.create( source: token, email: user.email, plan: plan.stripe_id ) user.stripe_customer_id = customer.id user.save! stripe_sub = customer.subscriptions.first else customer = Stripe::Customer.retrieve(user.stripe_customer_id) stripe_sub = customer.subscriptions.create( plan: plan.stripe_id ) end subscription.stripe_id = stripe_sub.id subscription.save! rescue Stripe::StripeError => e subscription.errors[:base] << e.message end subscription end end
The reason I know that the form is not receiving the stripeToken is because when I use binding.pry in that create and did this: 00:52:31 web.1 | 14: def create 00:52:31 web.1 | 15: @plan = Plan.find(params[:plan_id]) 00:52:31 web.1 | => 16: binding.pry 00:52:31 web.1 | 17: @subscription = CreateSubscription.call( 00:52:31 web.1 | 18: @plan, 00:52:31 web.1 | 19: params[:email_address], 00:52:31 web.1 | 20: params[:stripeToken] 00:52:31 web.1 | 21: ) 00:52:31 web.1 | 22: if @subscription.errors.blank? 00:52:31 web.1 | 23: flash[:notice] = "Thank you for your purchase! Please click the link in the email we just sent you to get started." 00:52:31 web.1 | 24: redirect_to authenticated_root_path 00:52:31 web.1 | 25: else 00:52:31 web.1 | 26: render :new 00:52:31 web.1 | 27: end 00:52:31 web.1 | 28: end 00:52:31 web.1 | [1] pry(#<SubscriptionsController>)> params 00:52:37 web.1 | => {"utf8"=>"✓", "plan_id"=>"1", "email_address"=>"someuser@test.com", "action"=>"create", "controller"=>"subscriptions"}
Notice that there is no params[:stripeToken]. Also, when I try the binding.pry in my create_subscription.rb service, this is what I get: 00:52:41 web.1 | 10: begin 00:52:41 web.1 | 11: stripe_sub = nil 00:52:41 web.1 | 12: if user.stripe_customer_id.blank? 00:52:41 web.1 | => 13: binding.pry 00:52:41 web.1 | 14: customer = Stripe::Customer.create( 00:52:41 web.1 | 15: source: token, 00:52:41 web.1 | 16: email: user.email, 00:52:41 web.1 | 17: plan: plan.stripe_id 00:52:41 web.1 | 18: ) 00:52:41 web.1 | [1] pry(CreateSubscription)> token 00:52:44 web.1 | => nil
What could be causing this and how do I fix it? |
