| Getting dynamic active li for one page bootstrap website Posted: 01 Sep 2016 07:31 AM PDT I want to have dynamic attribute active for li on a current page. I saw this topic:How to get Twitter-Bootstrap navigation to show active link?, but solutions not working for me. I don't have specific controllers for partials views. Method current_page doesn't work with href. I don't use defined routes, that's why don't have link_to. I tried to use data-toggle="pills", correctly marks on navbar current clicked a link, but not reference(not changed view). li a.waves-effect.waves-light href="#{root_path}#slider" Home li a.waves-effect.waves-light href="#{root_path}#about" About us li a.waves-effect.waves-light href="#{root_path}#price" Price li a.waves-effect.waves-light href="#{root_path}#contact" Contact

| 'Must contain specific value' on ActiveAdmin field Posted: 01 Sep 2016 07:18 AM PDT I want to test my models on ActiveAdmin by creating them manually. On one of my model, a field says 'Must contain specific value' whatever i write in it. This attribute can only contain a value from a list which is predefined. I suppose this field should not be a text field but a combobox filed with the values of this list. I looked for it on Google but can't find the answer.what I have tried upto is bellow f.input :modele, :as => :select, :collection => proc{current_route.modele.all}
but it doesn't work and worse I don't understand what I'm doing. |
| Rails: Form with custom button for update Posted: 01 Sep 2016 07:07 AM PDT I have an app for booking shifts. When you book you should be able to add a short comment (string) and then press the book button. I have the available shifts in a table, and want to have a text field like in a form, and add the (optional) text to the shift when you press the book-button. This is what I have so far, when you book a shift, it shows correctly as booked, but the comment doesn't is not added (is nil). Is there a smarter way to add a comment to a shift from the index view? Or how can I modify my code to work? Index: <% if shift.booked? && ( @booker == current_member || current_member.admin?) %> <td><%= link_to 'Avboka', un_book_shift_path(shift), method: :patch %></td> <% elsif shift.booked? && @booker != current_member %> <td></td> <% elsif shift.booked? %> <td><%= shift.comment %></td> <% elsif (!shift.booked? && prev_lshift.booked? ) || index == 0 %> <td><%= form_for shift, :url => book_shift_path(shift) do |f| %> <%= f.label :comment, 'Kommentar' %> <%= f.text_field :comment %> <%= f.submit "Boka" %> </td> <% end %> <% else %> <td></td> <% end %>
shift controller: def book @shift = Shift.find(params[:id]) @shift.update_attributes(shift_params) member = Member.find(current_id) if SubShift.find_by(booked_by: current_id) == nil flash[:danger] = "danger" redirect_to shifts_url elsif @shift.overlaps?(@shift, current_id) flash[:danger] = "Danger" redirect_to shifts_url else @shift.book(current_id) redirect_to shifts_url end end
shift model def book(current_id) self.update(booked:true, booked_by:current_id) end

| Testing aasm state transitions with rspec Posted: 01 Sep 2016 07:06 AM PDT I'm using aasm gem to handle state transitions in my project.

| Generate PDF with embedded video and manipulate objects Posted: 01 Sep 2016 07:02 AM PDT I'm using RoR to generate a PDF with embedded video, for which I use LaTeX with the media9 library. It generates PDFs correctly with embedded media (MP4, MOV, Youtube/Vimeo, etc...). I need to restyle the PDF layout in such a difficult way that doing it with LaTeX it's almost impossible. So I wanted to migrate to Prawn or other Ruby gem that's capable of creating nice-looking PDFs... but no embedded video support. So... Question: Is there a way that I can generate a PDF with the videos (LaTeX), a PDF with the "cool" layout (Prawn or other), and then I can "slice-merge" them in some way? Maybe extracting the raw PDF objects and merging them into the layout PDF? BTW, I've tested pasting the pages, but all of the PDF mergers I've tested break the media objects. Option B: find another Ruby gem that allows you to embed video media into a PDF. Thanks you all. |

| Capistrano deploy fails for repo that was moved from github to private git.. stil trying to contact github.. why? Posted: 01 Sep 2016 06:21 AM PDT I have a Rails 4 project that started at github and then it was moved to a private git repository. I can work perfectly with the repo (push, clone). I searched for references to the github repo somewhere in the code but none exists.. it must be something related to GIT and how the repository started..

| Rational behind having parent id of nested resources in RESTful URL Posted: 01 Sep 2016 06:50 AM PDT Given the following URL design for a nested resources in a RESTful API: /magazines/:magazine_id/ads/:id POST

| How to deploy the Backbone.js front end part of app to Heroku? Posted: 01 Sep 2016 06:17 AM PDT The project, which I am working on, is divided into back end (Ruby on Rails) and front end (Backbone.js) parts. Currently, we are trying to deploy both parts on Heroku, using separated repositories. We had no problems with back end part, but we found out that our front end is not working, getting internal server error 500. We attempted to trick Heroku into thinking that our front end files are PHP. Since, these files are not completely static, this trick was not working. |

| Run code if x times if item present Posted: 01 Sep 2016 06:58 AM PDT From my last question, I cant seem to get what I want. Below explains a lot better: external = ["apple"] internal = ["grapes", "pear", "mangoes", "apple"] external.each do |fruit| if not internal.include?("apple") # fruit will be in place of apple. puts "yes" # run code end end
So far this is printing once. How to get it print three times? In English I'm saying if apple is present, leave apple alone, give me the others, and run the code below. If 4 items are there and one is apple, run code three times. If apple not present, run code 4 times. I hope this is very clear. Thanks I need to be 100% precise: Internal is a Model (postgres) External is shopify api (array) I have saved shopify's product id in my database, Bar, on a column called foo. Bar.first.foo gives me the shopify's id. Bar will have other object with/without the shopify id. So If shopify is there, give me the rest. This is why I came up with: external.each do |fruit| if not internal.include?("apple") # fruit will be in place of apple. puts "yes" # run code end end

| Rails and Heroku - Rake db:seed only populates some databases and not others? Posted: 01 Sep 2016 05:51 AM PDT I have a rails app that I've been working on locally and have deployed to heroku. I have a lot of data that needs to be seeded that has worked well locally, with a small issue that I didn't pay much mind to. Basically I have a number of tables covering: - Feature,
- Addon,
- Budget,
- ProjectType
- Industry
etc. When I create/reset the local database and run the rake db:seed it seeds perfectly to each database. However, as its a WIP I keep adding new tables and running the seed rake db:seed, and noticed that where it should have been doubling up all of the seeded data (because I never cleared the data), it actually only duplicated this info on the Addon, and Feature tables. The other tables were unchanged. I thought nothing of it, until I started trying to run heroku run rake db:seed to populate my production database and noticed that in the logs it was also only populating the Addon and Feature tables, and skipping over the rest. An extract from some of my seed file (I've shortened with ... as they are very repetitive but all the same): #Populate the features table Feature.destroy_all Feature.create(id: 1, name: 'Contact form') Feature.create(id: 2, name: 'Blog') Feature.create(id: 3, name: 'Mailing list signup') ... ... #Populate the addons table Addon.destroy_all Addon.create(id: 1, name: 'Domain registration') Addon.create(id: 2, name: 'Hosting') Addon.create(id: 3, name: 'Create content') ... ... #Populating the industries table Industry.destroy_all Industry.create(id: 1, name: 'Accounting') Industry.create(id: 2, name: 'Airlines') Industry.create(id: 3, name: 'Alternative Medicine') ... ... # Populating the budgets table Budget.destroy_all Budget.create(id: 1, name: 'Micro', minimum: 250, maximum: 1000) Budget.create(id: 2, name: 'Simple', minimum: 1000, maximum: 2500) ... ...
I noticed that when I try populate the heroku database with heroku run rake db:seed the data all seems to "rollback". Here is an extract from the console: First I run heroku run rake db:migrate D, [2016-09-01T12:24:31.463009 #3] DEBUG -- : (1.8ms) SELECT pg_try_advisory_lock(4467995963834188590); D, [2016-09-01T12:24:31.476939 #3] DEBUG -- : ActiveRecord::SchemaMigration Load (1.9ms) SELECT "schema_migrations".* FROM "schema_migrations" D, [2016-09-01T12:24:31.507280 #3] DEBUG -- : ActiveRecord::InternalMetadata Load (1.8ms) SELECT "ar_internal_metadata".* FROM "ar_internal_metadata" WHERE "ar_internal_metadata"."key" = $1 LIMIT $2 [["key", :environment], ["LIMIT", 1]] D, [2016-09-01T12:24:31.518500 #3] DEBUG -- : (1.7ms) BEGIN D, [2016-09-01T12:24:31.522494 #3] DEBUG -- : (1.7ms) COMMIT D, [2016-09-01T12:24:31.524504 #3] DEBUG -- : (1.8ms) SELECT pg_advisory_unlock(4467995963834188590)

I did notice that of the tables, Addons and Features both have a has_and_belongs_to_many association with other tables while the rest of the tables that aren't working have a belongs_to association with some other tables. Not sure if that is just a coincidence? Thanks for any help! |
| Optimize long chain of associations Posted: 01 Sep 2016 05:51 AM PDT I have a Customer that goes to the Shop which has a Manager.

| Saving record to rails database from python script Posted: 01 Sep 2016 04:15 AM PDT I have Rails application with classic forum models like Post, Topic. Then I have python script using praw to download certain posts and topics from Reddit. (I know that I can use ruby version, but lets say we have to use this python script) I'd like to put them directly into my rails database. I can save them in json format and create rake task to upload them into my database, but I think I don't need to add this complexity and should somehowe save them directly to my rails db from this python script. How can I do this? |
| How to put filename in cron job (rails)? Posted: 01 Sep 2016 04:17 AM PDT I am using whenever gem. I am calling runner to run job. I called runner for the same job by 3 type. I am not sure which one working here. I used command whenever --update-crontab project_name then crontab -l Schedule.rb set :output, 'log/whenever.log' every 1.days , :at => '03:51 pm' do runner "SomeJob.perform_later", filename: '/app/jobs/some_job.rb' end every 1.days , :at => '03:51 pm' do runner "SomeJob.perform_later", filename: './app/jobs/some_job.rb' end every 1.days , :at => '03:51 pm' do runner "SomeJob.perform_later" end
Also these ran only once. I am having difficult time to debug here. Can anyone tell which one is correct? Also what is the correct way to debug in this scenario? Running crontab -l gives me this - 51,51,51 16 * * * /bin/bash -l -c 'cd /home/rahul/orthoweb && bin/rails runner -e production '\''InvestigationStopJob.perform_later'\'' >> log/whenever.log 2>&1
To run in development environment I ran this command - whenever --update-crontab --set environment='development'
But this gives me this message - ## [message] Above is your schedule file converted to cron syntax; your crontab file was not updated.

| Why Rails can use `if` as hash key but not in Ruby Posted: 01 Sep 2016 05:37 AM PDT In pure Ruby irb, one cannot type {if: 1}. The statement will not terminate, because irb thinks if is not a symbol but instead the beginning of an if statement. So why can Rails have before_filter which accept if as parameters? The guide have codes like: class Order < ApplicationRecord before_save :normalize_card_number, if: :paid_with_card? end
Same thing happens to unless as well. |
| Is it safe to use find params[:id] in Rails? Posted: 01 Sep 2016 05:34 AM PDT Expressions like the following are common in Rails: @project = Project.find params[:id] # example 1 @project = current_user.projects.find params[:project_id] # example 2
However I realize that find also accepts arrays! That would mean unexpected and potentially dangerous behavior of code, which is written with the assumption that @project is a single project, not an array. Now the question is: - should I typecast
params[:id].to_s every time I use it in find? - should I use strong parameters with
find in order to avoid arrays? find params.permit(:id)[:id])? (better than to_s if you don't want to convert nil to "") - are there any other alternatives or common practices?
The above vulnerability seems to be present only if the routes doesn't define a param with that name. For example: # SAFE routes.rb resources :projects # projects_controller.rb Project.find params[:id]
The query /projects/3?id[]=4&id[]=5 produces only {id: 3} as a param. This would make using Project.find params[:id] safe: however I cannot find any documentation for this behavior and I don't know if it's safe to rely on it: maybe it's just by chance. Furthermore the following is not equivalent at all and would create a vulnerability in the controllers: # Likely UNSAFE routes.rb # E.g.: # /projects?id=3 => params = {id: 3} # /projects?id[]=3&id[]=4 => params = {id: [3, 4]} put '/projects' => 'projects#update'

| Rails WHERE query on has_many relation works incorrect? Posted: 01 Sep 2016 03:43 AM PDT Cheers! Let's say I have User that has_many Accounts, Account model has logged_in (boolean) field. I wrote a AR query: User.joins(:accounts).where(accounts: { logged_in: false }), right? But then I check it User.joins(:accounts).where(accounts: { logged_in: false }).first.accounts.pluck(:logged_in) And could see that there are some accounts with mobiles.logged_in = true values. (0.1ms) SELECT "accounts"."logged_in" FROM "accounts" WHERE "accounts"."user_id" = $1 [["user_id", 373]] false false true
Why? |
