How to preserve '+' sign in params in rails 5 I have an uri like this /store?email=google+@gmail.com . Since '+' sign is allowed in email address, I need to preserve the plus sign. However, in rails 5, if I use params[:email] , I get google @gmail.com instead. How to prevent rails from converting '+' into space? I know we can first encode the url, and then decode it to preserve the '+' sign, but can I directly use params instead of extracting params from uri? Is there a way to preserve the plus sign in params ? /store?email=google+@gmail.com params[:email] google @gmail.com params params Also I tried using URI.decode_www_form_component params[:email] ,which still didn't work. And since the url is provided by external source I can't ask them to explicitly encode + as %2B . URI.decode_www_form_component params[:email] + %2B Any suggestions will be appreciated! How are you using that URI? Some things will URI escape,...

Using “ApplicationController.new.render_to_string” in a Rails api app (config.api_only = true) I have a Rails 5 app build as an api app: # config/application.rb module MyApp class Application < Rails::Application config.api_only = true end end In one of my controller actions I need to render some Ruby flavoured html, and then serve it back in the json response. A standard Rails app do this: # app/controllers/my_controller.rb def my_action html = ApplicationController.new.render_to_string("my_erb_or_haml_file", locals: {foo: "bar"}, layout: false) render :json => {html: html}, :status => :ok end However, for my slimmed api app ApplicationController.new.render_to_string seems to just render " " . This confuses me, because I would expect it to either serve the content or raise an exception. ApplicationController.new.render_to_string " " Any suggestions what route I should take in order to generate Ruby flavoured html? This ques...

How can run. Rails web app in AWS Lambda server AWS (Amazon web service) introduced serverless computing commonly known as AWS Lamda, We can store the asset in S3 then deploy a lambda function to handle our business logic. Lamda will support ruby script. Is there any way to run a dynamic web framework like rails or Sinatra in Lambda server? 1 Answer 1 The main problem here is that AWS Lambda does not currently support Ruby. AWS Lambda supports code written in Node.js (JavaScript), Python, Java (Java 8 compatible), and C# (.NET Core) and Go However if you really want to run a rack (including Sinatra and Rails) based app it is possible, by bundling your own version of ruby in your deployment package. This blog post goes into detail about how to do that. Whether this is a good idea probably depends on what you are trying to achieve. By clicking "Post Y...

Deploy Andorid/iOS app on free Heroku account for Stripe payments I'm creating an application for Android/iOS both and implemented Stripe for payments, so I've deployed it on Heroku for free. So my concern is that can I run Stripe on the free account (Heroku) without any issues (means we can deploy/run application by using live secret key as well or is it only for testing purpose) or do I need to use my personal paid server for the Stripe deployment to interconnect with android/iOS apps. Referring to this link: Stripe for free - Example App Backend (Deploy to Heroku) and what does this sentence mean This is intended for example purposes only: you'll likely need something more serious for your production apps. which is available on the above link. 1 Answer 1 I'm using the stripe/example-ios-backend codebase (Ruby), so after spending a lot of time by searching on Internet and also tal...

Rails ActiveRecord include non-related tables into query I have model Benchmark . It has method scores which is doing some calculations. During this calculations, it uses all values from table Synonyms . It has the corresponding model, but these models ( Benchmark and Synonym ) are not related to each other. I always need all synonyms in any of my benchmark calculation. Synonyms are used to replace values in a couple of strings which are Benchmark attributes. To get the synonyms I simply use the Synonym.all method inside my scores method: Benchmark scores Synonyms Benchmark Synonym Synonym.all scores def scores @synonyms ||= Hash[Synonym.all.map {|synonym| [synonym.synonym, synonym.word]}] @scores ||= # replacing substrings in Benchmark name using synonyms end So far so good. But now I want to perform bulk calculations for all the benchmarks I have. This obviously leads to N+1 query problem — each scores method calls Synonym.all method. Rails is smart enough to cache...

Finding posts under a category name keyword with pg_search on Rails 5 I'm using gem pg_search and doing multi-search for Website and Post tables. I am able to search by records title, but I also want to be able to search records based on categories they belong to. pg_search So, for example, when I type "typographic" (category name) to search input, all Website and Post records under that category should be listed, as well as all records that have "Typographic" in the title.

fallback method not working in i18n-js with rails 2.3 I am integrating I18n-js in a Rails application. The integration is working fine along with the translations.But the problem I am facing is that when the required translation is not present in a particular language , say for example I selected Afrikaans as my language then in that case the fallback method should execute showing me the translation present in the default language.But its not happening and I get the error [missing "af.credential_requests.add" translation] This surely means that the fallbacks method is not working. Though I have I18n.fallbacks = true; in my I18n-js. Please help.

How do I customize the banner/header image of Hyrax/Samvera? I'm a web developer, trying to get my bearings with the Samvera-based application known as Hyrax. I'm using version 2.1.0.rc3. I have done some devops-type stuff with Hyrax so far, I have an app running on AWS and can deploy new code to that stack via Capistrano... but I'm tired of looking at the default header image... time to move in... however, I'm stuck. I've tried searching for terms like image-masthead in the application code, but so far, no luck. I have a suspicion this is a frequently asked question, so I'd accept as an answer just a link to a howto. But... in my searching for an answer I have not yet found such a document. So, I'm turning to Stack Overflow. Help? @sticky-bit what was wrong with the edit? Hardy is my colleague; I was just helping make their first post more specific, since it's about the banner image. And so our community members can find this...
