| Select option from dropdown menu and show list based on option chosen rails Posted: 13 May 2016 07:19 AM PDT I have a dropdown list populated with Managers in my view... <div class= "container"> <div class="col-md-11"> <select class="form-control"> <% if current_admin.manager_approvals.blank? %> <option>No Sub-Accounts added</option> <% elsif current_admin.manager_approvals.all? { |ma| ma.manager_approved == false }%> <option>No Sub-Accounts approved</option> <% else %> <% current_admin.manager_approvals.each do |ma| %> <% if ma.manager_approved == true %> <option value="<%= ma.id %>"><%= ma.manager_company %> | <%= ma.manager_phone %></option> <% end %> <% end %> <% end %> </select>
I want it so that when the user selects a Manager from the dropdown list, my index partial will show only the items associated with that Manager. I am unsure how to make the selection automatically query when chosen & how to display only the objects associated with that particular manager in the index list. Here is the index list as it stands now. <tbody> <% if #currently_chosen_manager#.reportapprovals.blank? %> <tr> <td width="100%">No reports available</td> </tr> <% elsif %> <% #currently_chosen_manager#.reportapprovals.each do |ra| %> <% if ra.tenant_approved == false %> <tr> <td width="25%"><%= ra.tenant_last_name %></td> <td width="25%"><%= ra.tenant_phone %></td> <td width="25%"><%= ra.date_approved %></td> <td width="25%"><%= link_to "View Report", {:controller => "managers/reports", :action => "show", :id => ra.tenant.report || ra.report}, :method => :get, class: "btn-default btn-sm" %></td> </tr> <% elsif %> <% #currently_chosen_manager#.reportapprovals.each do |ra| %> <% if ra.tenant_approved == true && ra.tenant.confirm_info == false %> <% end %> <% end %> <% else %> <tr> <td width="100%">No reports in progress, request a new report today!</td> </tr> <% end %> <% end %> <% end %> </tbody>

| Installing rails on Ubuntu Bash Windows 10 Posted: 13 May 2016 06:12 AM PDT I am using Windows 10 Insider built with Bash enabled. lsb_release shows its Ubuntu 14.04 LTS. So, I was wondering finally I can install RoR on Windows 10 and not use other installers. Because they say its Ubuntu on Windows. I am noob at rails and I am following GoRails Guide by Chris Oliver to set RoR on Ubuntu 14.04 Win10. I tried both method using RVM & Rbenv but I ended up with errors I also asked Chris to write a guide for this on his website and he thought it would be a great idea and but his only concern was opening up ports with Linux Software on Windows and connect to it I am sure someone will soon find a way to install rails on Windows 10 but meanwhile I want to know if its possible or not? If yes what is it that I am doing wrong. Help me to fix it. Also what should I use for this RVM or RBENV. Which would be better in this case? Note: Please let me know if this looks like two different questions. I will edit it. Please don't downvote because I don't even know if its possible or not. Fixing errors is the later part.

I have the following error everytime I try to create a character with a image. everything works fine when I don't add a image: ActionController::InvalidAuthenticityToken I know that there are a few different other similar questions already asked on the forum but I can't seem to find the answer to my problem. I am using Rails 4.2.6. I tried to add the gem remotipart but it didn't fix my issue. create.js.erb code: $("#characters").append("<%= escape_javascript(render @character)%>");

| rails text_field / text_ara empty string vs nil Posted: 13 May 2016 06:55 AM PDT I'm not even sure if I have a problem, but I just don't like that my text_fields and text_areas get saved in the db as empty string instead of nil. I'm playing with the null object pattern and just realized if I create a profile but don't fill in the location field and then call <%= @user.profile.location.upcase %> then it doesn't blow up since location is a string even it it's empty. Is this the rails convention to have it this way? If so, then why? It's weird a bit since let's say there is a number_of_pets attr on the profile and then I try to call something like <% if user.profile.number_of_pets.odd? %> <%= @user.profile.first_name %> has odd number of pets <% end %>
then it blow's up since I can't call nil.odd?. form as usual, so it will saved as empty string if not filled <%= form_for @profile, url: user_profile_path do |f| %> <%= f.label :city %> <%= f.text_field :location, class: 'form-control' %> ......

| Integrating Bootsy with Mailboxer for the image uploads. Posted: 13 May 2016 04:45 AM PDT I am a ruby on rails developer and I got a task to work on the 'wysiwyg-editor', so I searched a few ways on how to use it, and found 'Bootsy'(https://github.com/volmer/bootsy) to be easiest of all which includes file uploads too. I followed the documentation and first applied integrated it to my message model, and added the 'include Bootsy::Container' line to it to get the uploads working. class Message < ActiveRecord::Base include Bootsy::Container end
SO, I can call @message.bootsy_image_gallery.images using the object of message model. I uploaded the images to the message model, and it worked fine for me. Now the requirement has changed and the message model is removed and I added mailbox for the conversations insted of a simple plain message model. Now I dont have a model to add the 'include Bootsy::Container' line, so I gone through the mailbox and found that the 'Mailboxer::Notification' model is saving the attachments. So I added, to 'Mailboxer::Notification' but for no use. class Mailboxer::Notification < ActiveRecord::Base include Bootsy::Container ******************* ******************* end
I also tried in 'Mailboxer::Message', but noavail. class Mailboxer::Message < Mailboxer::Notification include Bootsy::Container end

But every-time I tried to create new entry it goes behind the previous one. index.html.erb <div class="container"> <div class="row"> <div class="s12 m6 l6 col"> <% @students.each do |student| %> <div class="card medium hoverable"> <!-- Card Image --> <div class="card-image waves-effect waves-light waves-block"> <%= image_tag student.avatar.url(:large), class: "activator" %> </div> <!-- Card Content --> <div class="card-content"> <span class="card-title activator grey-text text-darken-4 card-modification"> <!-- Student Name --> <%= student.Student_Prefix %> <%= student.First_Name %> <%= student.First_Name %> <%= student.First_Name %> <i class="material-icons right">menu_vert</i> </span><br><br> <!-- Button --> <p class="center-align"> <%= link_to student, :class=> "btn waves-light waves-effect grey darken-4" do %> Show <% end %> <%= link_to edit_student_path(student), :class=> "btn waves-light waves-effect grey darken-4" do %> Edit <% end %> <%= link_to student, method: :delete, data: { confirm: 'Are you sure?' }, :class=> "btn waves-light waves-effect grey darken-4" do %> Delete <% end %> </p> </div> <!-- Card Reveal --> <div class="card-reveal"> <!-- Other Details --> <span class="card-title grey-text text-darken-4"> More Student Details <i class="material-icons right">close</i> </span> <!-- Horizontal Line --> <hr> <!-- Card Paragraph --> <table class="bordered centered"> <tbody> <!-- Department And Branch --> <tr> <th>Course</th> <td><%= student.Department_Type %> <span>in</span> <%= student.Branch %></td> </tr> <!-- Date of Birth --> <tr> <th>D.O.B</th> <td><%= student.Date_Of_Birth %></td> </tr> <!-- Gender --> <tr> <th>Gender</th> <td><%= student.Gender %></td> </tr> <!-- Class Roll Number --> <tr> <th>Class Roll Number</th> <td><%= student.Class_Roll_Number %></td> </tr> <!-- University Roll Number --> <tr> <th>University Roll Number</th> <td><%= student.University_Roll_Number %></td> </tr> <!-- Mobile Number --> <tr> <th>Mobile Number</th> <td><%= student.Mobile %></td> </tr> <!-- Email Address --> <tr> <th>Email Address</th> <td><%= student.Email %></td> </tr> <!-- Postal Code --> <tr> <th>Postal Code</th> <td><%= student.Postal_Code %></td> </tr> <!-- Address --> <tr> <th>Address</th> <td><%= student.Address %></td> </tr> </tbody> </table> </div> <% end %> </div> </div> </div> </div>

| Name Validation API? Posted: 13 May 2016 04:13 AM PDT Does anyone know of a service/API that we can use in our Rails app that will check a name to determine if it's likely real or fradulent? So if a user enters themselves as Barack Obama, it should be fradulent. Likewise if they did something like John Doe, also so. But if they did a real name like John Reed, it would be fine. Basically trying to up the quality of data we're getting entered when registering and I'm having trouble finding an API. One idea is maybe using the USPS address validation and trying to validate that against the entered name/address. |
| Heroku access remote postgresql Posted: 13 May 2016 04:10 AM PDT I have an heroku app and 3 different databases on 3 different servers (including localhost) I tried to connect to each of them and i always get PG::ConnectionBad: could not connect to server: Connection timed out
My DATABASE_URL is correct and the app runs smoothly with heroku's native database At first i thought it was the firewall from my hostings but i created a localhost db, opened both 5432 and 5433 ports and still heroku can't connect... i submited a ticket but no response so far. Can someone help me? database.yml development: port: 5432 host: host adapter: postgresql encoding: unicode database: database pool: 5 username: user password: pass test: port: 5432 host: host adapter: postgresql encoding: unicode database: database pool: 5 username: user password: pass production: port: 5432 host: host adapter: postgresql encoding: unicode database: database pool: 5 username: user password: pass

| How can I model the association in the following situation.? Posted: 13 May 2016 04:29 AM PDT I have the following association between entities in the system: Store Vendor and User - store can have many vendors,
- vendor can belong to multiple stores.
- A user can have multiple stores, but if its a user who is related to vendor, say a person who works for that vendor, then the behavior of that user changes.
Also, for a store there can be multiple roles. I tried polymorphic association, but since the behavior of the user changes depending on roles and whether he is a store user or a vendor user, I cannot use that. STI can also not be used since a vast amount of columns will differ. Any ideas will be helpful. |
| Rails, is it a good practice to create a method without a view? Posted: 13 May 2016 05:21 AM PDT I am relatively new to Rails, so I still have a lot of questions. I am creating an administration panel right now. I have a model AdminUser, a folder admin_users in my views with 2 views only, dashboard and index and an admin_users_controller which is: class AdminUsersController < ApplicationController def dashboard end def index end def login if params[:admin_user][:username].present? && params[:admin_user][:password].present? found_user = AdminUser.where(:username => params[:admin_user][:username]).first if found_user authorized_user = found_user.authenticate(params[:admin_user][:password]) session[:admin]=params[:admin_user][:username] end end if authorized_user redirect_to :controller => 'admin_users', :action => 'dashboard' else render :nothing => true, :status => :ok end end end
Although I have a method for login, I do not have a view for it, because I don't really need it. But the fact that Rails searches for a view make me think that I am doing something wrong; or at least not doing something the Rails-y way. Should I do something in another way? I would love to hear your suggestions. Thank you |
| How to embed the iPython Notebook in a Rails application? Posted: 13 May 2016 03:43 AM PDT I have an iPython Notebook that needs to be embedded into my Rails application. I have two options for doing it: - Just rendering the
.ipynb file on the page (like GitHub does) - (desirable option) Embed the notebook with the kernel and interactive elements.
The notebook I have is quite large and it uses python-specific tricks and libraries, so rewriting it into the ruby notebook is not a good option.
So, how can one render the iPython Notebook file on the web page (like GitHub does) or how to embed the fully-functional iPython Notebook into the Rails application? |

| Omniauth Facebook login redirects to signup if user exists Posted: 13 May 2016 04:29 AM PDT I'm playing around with the omniauth-facebook gem to log into a devise session through a facebook account. When I click the "Sign in with facebook" link, everything goes well: a new account is created, I'm signed in and bounce back to the homepage with a message confirming my new session (very good!). Problem: However when an account already exists, upon clicking the link I am redirected to the user/sign_up page. I've been following this documentation from the Devise wiki. There is a good deal of documentation on similar errors here, here, here and here. Each of the solutions, however, are already implemented in my app (as far as I can tell) OR (in the case of the last link) seem to be based on an older configuration model that seems sufficiently different from the wiki that I'm not sure it's applicable. My best guess is that it has something to do with the callbacks controller, as @user.persisted? seems to be coming up false.This leads me to believe that my definition of @user is not correct. See below: class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController def facebook logger.debug "Inside facebook" # You need to implement the method below in your model (e.g. app/models/user.rb) @user = User.from_omniauth(request.env["omniauth.auth"]) logger.debug "User is #{@user}" if @user.persisted? logger.debug "@user.persisted?" debugger sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format? logger.debug "user exists" else session["devise.facebook_data"] = request.env["omniauth.auth"] redirect_to new_user_registration_url end end def failure redirect_to root_path, alert: "Login failed" end end
Additionally, my user model is as follows: class User < ActiveRecord::Base # Include default devise modules. Others available are: # :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :omniauthable, :omniauth_providers => [:facebook] def self.from_omniauth(auth) where(provider: auth.provider, uid: auth.uid).first_or_create do |user| user.provider = Devise.friendly_token[0,20] user.email = auth.info.email user.password = Devise.friendly_token[0,20] user.fname = auth.info.first_name user.lname = auth.info.last_name end end end
Any suggestions would be certainly welcome! Thanks in advance. |
