| Managing access to a file with a direct link Posted: 27 Jul 2016 07:41 AM PDT I have a rails app where I upload files. I'm using gem cancan for managing access to files. The files are stored on the disk. Is it possible to manage access to a file or restrict/allow it even when a user has a direct link to it? Note I'm not using nginx or apache, it's a local application, therefore at best it's unicorn or simply the standard Rails web server. |

| Need double colon as prefix for constant lookup? Posted: 27 Jul 2016 05:50 AM PDT I use builder templates within a legacy Rails application. But I got the following error after upgrading to Rails 4.2 and making some adaptions. Formatter cannot be autoloaded from an anonymous class or module
The class Formatter is required before rendering the XML. The template has some strange extensions of the xml object. Formatter # no error class << xml def some data(Formatter.format(@input)) # raises the error above end end xml.instruct!() xml.test { xml.some }
I have no idea how the constant got lost. I have the same problem with classes form the standard library like BigDecimal. It seems that all made require calls are reseted in the context. Prefixing all classes with :: is the workaround. Then the Rails constant lookup is triggered and reloads the classes. Any ideas how to get the constants back? |

In my deploy.rb I call the task at the very end with: after 'deploy:publishing', 'fileservice:migrate'
For some reason I keep getting an error saying: NoMethodError: undefined method `within' for main:Object
I have no idea where to look or what might be wrong... When googling I get a lot of "NoMethodError" hits but none about the 'within' method and most are general Ruby errors. Where should "within" be defined? I dat a ruby on rails thing? Or capistrano? Hopefully someone knows where to start looking or which library / script to include! UPDATE: I just discovered that none of the methods work. When removing lines I got the same error for "info" and "execute".... So I guess somewhere, something is missing..... |

The User has_many :chasings and the Chasing model belongs_to :user and has_many :comments I created a migration to add a reference to :chasings for :user, so I could call Chasing.user: class AddUsersToChasings < ActiveRecord::Migration def change add_reference :chasings, :user, index: true, foreign_key: true end end
So I can now successfully assign chasings to users, however I'm wanting to find out the best way of assigning comments in chasings to users using a similar select list as below (this is the code for selecting users for chasings): <%= f.select :user_id, options_for_select(User.all.map {|c| [c.name, c.id]}, @chasing.user_id), { :include_blank => "Please select user"}, {:class => "form-control"} %>
Anyone got any ideas on how I'd create the relationship between comments and users, if the comments already belong_to the chasing? |

UserNotifierMailer.sample_email(@user).deliver redirect_to posts_path else flash[:alert] = "Your new post couldn't be created! Please check the form." render :new end end
My mailer looks like this: class UserNotifierMailer < ApplicationMailer default from: "from@example.com" def sample_email(user) @user = user @url = 'http://www.google.com' mail(to: @user.email, subject: 'Sample Email') end end
and in my development.rb I have these settings: config.action_mailer.raise_delivery_errors = true config.action_mailer.perform_deliveries = true config.action_mailer.default_url_options = { host: 'localhost', port: 3000 } config.action_mailer.delivery_method = :smtp config.action_mailer.smtp_settings = { address: "smtp.gmail.com", port: 587, domain: "gmail.com", authentication: "plain", enable_starttls_auto: true, user_name: "my_gmail_username", password: "my_gmail_password" }

| Attach an instance of model within Migration Posted: 27 Jul 2016 06:44 AM PDT I'm creating a User model which is associated with a Cart model. At the moment the User is created, a Cart should automatically be created. In the app, I added the call Cart.create into the create method of my UserController. When I try to seed the data, however, I need to have two lines: User.create and Cart.create and attempt to make this work for only one line of User.create. Is it possible to move the Cart creation code into method change (CreateUsers, Migration)? |

| Compress and upload multiple images [duplicate] Posted: 27 Jul 2016 03:43 AM PDT This question already has an answer here: I am working on a form with 8 images to be uploaded using the camera capture(in phone) / file upload(in desktop) where each image will be of minimum size 2 MB.. It takes too long to upload the file to the server. I need to upload the images through form submit and not by AJAX.. Is there any way to compress large image and then upload it to server. How can I submit the form where it should take minimum time to submit.. I came across CANVAS with HTML5 but, I don't know whether it will be used for this situation, if it can be used then please give me some example code.. Thank you.. |
