| Uploading files by ng-file-upload and paperclip Posted: 21 Sep 2016 08:10 AM PDT I spent a lot of times with ng-file-upload and rails paperclip and stuck((. In standard view with new.html.erb paperclip works perfect. But with ng-file-upload browser returns an error. Internal Server Error bad content body
Or if I change upload in my controller: afisha: {file: file} => to file: {file: file}

Here is my controller: $scope.upload = function (file) { console.log(file); Upload.upload({ url: 'http://localhost:3000/public', method: 'POST', afisha: {file: file} }).then(function (resp) { console.log('Success ' + resp.config.data.file.name + 'uploaded. Response: ' + resp.data); }, function (resp) { console.log('Error status: ' + resp.status); }, function (evt) { var progressPercentage = parseInt(100.0 * evt.loaded / evt.total); console.log('progress: ' + progressPercentage + '% ' + evt.config.data.file.name); }); };

| Attaching AXLSX view to mail Rails Mailer Posted: 21 Sep 2016 08:07 AM PDT According to the GitHub Page for the axlsx gem I should use this syntax to render a xlsx view to a file and attach it: xlsx = render_to_string handlers: [:axlsx], formats: [:xlsx], template: "users/export", locals: {users: users} attachments["Users.xlsx"] = {mime_type: Mime::XLSX, content: xlsx}
Here is my mail method: xlsx = render_to_string(handlers: [:axlsx], formats: [:xlsx], template: 'v1/reports/reportxyz', params: {start_date: '2016-09-12', period: 'weekly'}) attachments["report.xlsx"] = {content: xlsx, mime_type: Mime::XLSX} mail(to: "my@email.address", subject: "Report", format: "text")
However I get this error when I try and call the mailer method: ActionView::MissingTemplate: Missing template layouts/mailer with {:locale=>[:en], :formats=>[:xlsx], :variants=>[], :handlers=>[:axlsx]}. Searched in: * "path/to/project/app/views"
Why is the render_to_string method affecting what the mailer view the mailer is trying to render? locgially I don't have a mailer.xlsx.axlsx file in my app/views/layouts folder but rather the mailer.text.erb I am trying to use as with other emails. |

| Rails - bundle error Posted: 21 Sep 2016 07:55 AM PDT I created a new project, run all basic commands and everything worked fine. But now I tried to add some gems and when I run bundle, I get the error: /usr/lib/ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find bundler (>= 0) amongst [bundler-unload-1.0.2, did_you_mean-1.0.0, executable-hooks-1.3.2, gem-wrappers-1.2.7, minitest-5.8.3, net-telnet-0.1.1, power_assert-0.2.6, rake-10.4.2, rubygems-bundler-1.4.4, rvm-1.11.3.9, test-unit-3.1.5] (Gem::LoadError)

| Query appears to work in console but cannot get data in view Posted: 21 Sep 2016 08:14 AM PDT I am trying to use this query pages_controller.rb # GET /pages/1 # GET /pages/1.json def show @page = Page.where('category_title = ?', params[:category_title]).where('slug = ?', params[:slug]) end
routes.rb match ':category_title/:slug', :via => 'get', :controller => :pages, :action => :show
I get an error in the view of "undefined method' for the properties of that page (id, slug, etc.). The query looks right to me in the console but when the page loads it is not actually getting any data. 
If I print out a count it comes back as 1, which is correct. 
I have looked at a few posts about creating named routes and thought I had it, but clearly I am missing something. Any help with what part of this I am missing would be greatly appreciated. |
| Rails - how to delimit a reserved sql keyword Posted: 21 Sep 2016 07:43 AM PDT I am working on a sort routine that worked in other apps/sections. However, it appears that the resulting query doesn't work because the associated table is named user which apparently is a reserved SQL word. The fix is to have the query reference '[user].name' instead of user.name The line that is causing the problem is @workflows = @workflows.includes(:user).order(params[:sort] + ' ' + params[:direction])

| How can I authenticate a user with admin attribute for rails_admin with devise Posted: 21 Sep 2016 07:15 AM PDT I am fairly new to ruby on rails. I habe set up a mysql database, connected it with a rails app, installed the devise gem and rails_admin gem. So far so good, everything works as it should. Now I also added a usergroup attribute to the users table, to identify different user group. Only "admin" should be allowed to access rails admin. I already use the predefined commands in /app/config/initializers/rails_admin.rb RailsAdmin.config do |config| ### Popular gems integration ## == Devise == config.authenticate_with do warden.authenticate! scope: :admin end config.current_user_method(&:current_user) ## == Cancan == # config.authorize_with :cancan ## == Pundit == # config.authorize_with :pundit ## == PaperTrail == # config.audit_with :paper_trail, 'User', 'PaperTrail::Version' # PaperTrail >= 3.0.0 ### More at https://github.com/sferik/rails_admin/wiki/Base-configuration ## == Gravatar integration == ## To disable Gravatar integration in Navigation Bar set to false # config.show_gravatar true config.actions do dashboard # mandatory index # mandatory new export bulk_delete show edit delete show_in_app ## With an audit adapter, you can add: # history_index # history_show end end
This works so far that you have to login before you can access the page. Now there also has to be a check wether current_user.usergroup = 'admin'. In devise this is also explained as one possible method to 'handle' usergroups. https://github.com/plataformatec/devise/wiki/How-To:-Add-an-Admin-Role But I am pretty confused how to insert this check into the config that way. |
| Rails 4 add nested values from static fields Posted: 21 Sep 2016 06:57 AM PDT I'm using the cocoon gem to add some nested values to my form. So far everything works fine. Now I would like to change the form and have a single row of input fields and when the user clicks "add", the data in the input fields is added to the nested fields collection and shown below the input fields. Here is a simple mockup of what I'm trying to accomplish: 
I'm pretty new to rails and I'm not sure how to accomplish this. What I have done so far is to create three virtual attributes, one for Area, Product and Quantity. This takes care of the static data entry fields on the form but I am unsure how to add the data to the dynamic portion of the form. I can't figure out how to pass the data to cocoon. How can I pass the data to cocoon and create the nested item? Is there a gem that would work better for this scenario or a better overall approach? Your help is greatly appreciated. |

As I am running rails test, I am getting error LoadError: Unable to autoload constant User_type, expected app/models/user_type.rb to define it
Here is my model: class UserType < ActiveRecord::Base belongs_to :user validates :type, presence: true, length: { maximum: 100 } end
Below is the controller and test file class UserTypeController < ApplicationController def index @user_type = User_type.all end def new @user_type = User_type.build(user_type_params) end private def user_type_params params.require(:user_type).permit(:type) end end
Testing model: require 'test_helper' class UserTypeTest < ActiveSupport::TestCase # test "the truth" do # assert true # end def setup @user_type = User_type.new(id:2,type:"test") end test "is_valid" do assert @user_type.valid? end end
I wanted to do some basic "is_valid" test and I got an error described above. I have also dropped last model "user_type" and created it as "UserType" but It didn't work. |
| How can I serve static content in my Rails 2.3 application using Nginx? Posted: 21 Sep 2016 07:04 AM PDT The users of this legacy application I'm supporting can run reports, and the reports are put in a directory structure like: /customers/<account number>/output/
Where <account number> is there 5-digit account number. nginx is showing 404 on these files.
But not on all of them! There appears to be no rhyme or reason as to what is downloading and what isn't. I have carefully checked permissions and ownership of both the files and the directory paths. There is zero difference. |
| Ruby on Rails 5 - stable version? Posted: 21 Sep 2016 06:28 AM PDT I'm going to work on a new project and I would like to know the best rails version to use.

| caching in-between backend and frontend application Posted: 21 Sep 2016 06:13 AM PDT I am running a Rails API and ReactJS SPA architecture for my site. Are there any solid solutions for caching so that the number of client-side requests to the Rails API is restricted through an intermediary cache? Looking for something simple and efficient. Thank you! So this is what I have in mind: Client-side data request (reactjs application) --> cache (independent cache server) --> cache server restricts # of requests to API (ie a time based expiration, etc) --> accesses API if necessary to get new data |
| Heroku is serving old assets for Rails 5 application Posted: 21 Sep 2016 07:02 AM PDT I've deployed a new version of a Rails 5 app on Heroku, running on cedar-14 stack. It didn't precompile while deploying, so I did heroku run rake assets:precompile manually. Still, I can see it includes old assets while requiring css and js files. My files are in app/assets so it's not possible that directory isn't in assets compile path. My config on application.rb and production.rb: config.assets.compile = true # I checked the environment variable, it responds to 'enabled', # which would return true for the option. config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present? # Which I changed to expire old assets. config.assets.version='1.1'
I tried these, but they didn't work: $ heroku restart$ heroku run rake assets:precompile$ heroku run rake assets:clobber The weird thing with these is that they do not affect assets in heroku server, which I checked with $ heroku run ls public/assets. Even after $ rake assets:precompile, even though it says this: WRITING /app/public/assets/application-{VERY_LONG_HASH}.js WRITING /app/public/assets/application-{VERY_LONG_HASH}.js.gz WRITING /app/public/assets/application-{VERY_LONG_HASH}.css WRITING /app/public/assets/application-{VERY_LONG_HASH}.css.gz
when I peek with the $ heroku run ls public/assets, I still see old assets staying there. EDIT: I solved it by deleting all the local assets in public/assets, recompiling them with $ rake assets:clean && rake assets:precompile and including these assets in my git repository. Here is one concern: Shouldn't heroku be responsible of compiling my assets on the fly? I think I shouldn't be compiling my assets everytime I deploy my application. Thanks. |

| Prevent adding inputs with cocoon Posted: 21 Sep 2016 05:05 AM PDT I'm using cocoon for a nested form that accepts different kind of files. Everytime I click on the button, a new input is created, and once the user selects a file, the preview appears inside of the input. BUT, if for some reason, my user cancels the file upload (by clicking on the usual 'cancel' button, in the file selection window), the extra input is still added, with nothing in it, and when the form is submitted, the empty input is still processed, resulting in an extra, unnecessary record. Is there a way to prevent this behaviour, so that if the file selection is cancelled, the extra input is destroyed ? |
