erb

问题 I'm migrating from assets pipeline to Webpack 2 in a Rails 4 app. Everything seems to work fine, except for the JS code using jQuery within a .js.erb view. The content of the webpack.config.js is as follows (omitted code for fingerprinting and compression): const path = require('path') const webpack = require('webpack') const ExtractTextPlugin = require('extract-text-webpack-plugin') const jsOutputTemplate = 'javascripts/[name].js' const cssOutputTemplate = 'stylesheets/[name].css' module

问题 I am creating a stripe_card_token with: Stripe.createToken(card, charge.handleStripeResponse) In my charges.js.coffee file jQuery -> Stripe.setPublishableKey($('meta[name="stripe-key"]').attr('content')) charge.setupForm() charge = setupForm: -> $('#new_charge').submit -> $('input[type=submit]').attr('disabled', true) if $('#card_number').length charge.processCard() false else true processCard: -> card = number: $('#card_number').val() cvc: $('#card_code').val() expMonth: $('#card_month').val

问题 Imagine in rails I have @template that is an instance of ActionTemplate::View . Question is: How can I convert @template whose @template.source is <%= "hello from erb" %> to hello from erb ?? thanks 回答1: Try this... ERB.new(@template.source).result ERB#new 回答2: Well... messing around with ActionView::Template.new outside of Rails is not really recommended. You need a ton of stuff setup beforehand (init and render) If you do want to just use ERB, then go with this example require 'erb' x = 42

问题 I built a page that is rendered differently depending on params . The logic is something like this: <% if params[:x] == "1" %> <!--render version A--> <% elsif params[:x] == "2" %> <!--render version B--> <% elsif params[:x] == "3" %> <!--render version C--> <% end %> I want each version to have two links which link to the other two versions, so the urls should have different params. I have a url string original_url , which is: "localhost:3000/page?x=1" and want to replace its parameter

问题 I am using bootstrap-markdown to add a markdown editor to my page and save the content parsed to html in the database. The problem is that (although i believe it should) it does not save the html result but the raw text instead. this is my code: <div class="well col-md-10 col-md-offset-1"> <%= form_for(:post, :url => {:action => 'create'}) do |f| %> <%= f.text_field(:title, class: 'form-control')%> <%= f.text_field(:description, class: 'form-control')%> <%= f.text_area(:content, rows: 15,

问题 I have been having a lot of trouble getting my background images to show up when I deploy my rails app to Heroku.

So application.css would need to be application.css.erb. I tried renaming the
