Loading .coffee files via a view in Rails

由 左心房为你撑大大i 提交于 2019-12-11 01:55:22
问题 My controller is as follows: class CommentLoaderController < ApplicationController respond_to :js def show puts 'here' @client_id = params[:id] respond_with @client_id end end It loads a .js file which has some .erb markup in it. I'd like to load a CoffeeScript file, compiled to JS on the fly. Is this possible with Rails 3? 回答1: I think this blog post that one of my colleagues wrote today might help http://www.storm-consultancy.com/blog/development/random-bits/todays-gotcha-when-coffeescript

Replace properties in one file from those in another in Ruby

由 ⅰ亾dé卋堺 提交于 2019-12-11 00:37:39
问题 I want to replace properties in one file from those in another. (I am new to ruby, and read about Ruby and YAML. I have a Java background) Eg. File 1 server_ip_address=$[ip] value_threshold=$[threshold] system_name=$[sys_name] File 2 ip=192.168.1.1 threshold=10 sys_name=foo The ruby script should replace the $ values by their real values (I do not know if $[] is the format used in ruby. Also do Files 1 and 2 have to be YAML files, or erb files?) and produce File 1 as : server_ip_address=192

sprockets sass partial erb extension

由 被刻印的时光 ゝ 提交于 2019-12-10 16:21:46
问题 I have noticed that with the latest rails and sprockets versions (3.2.1 & 2.2.0) there seems to be a problem when the erb file extension is added to a sass partial. e.g. if somestylefilename.css.sass is renamed to somestylefilename.css.sass.erb and the file contains a declaration of a sass variable that uses erb, vis:- $background-colour: <%= '#fff' %>; all is ok. However if a sass partial is renamed from say _sharedpartial.css.sass to _sharedpartial.css.sass.erb then the same variable

问题 i have: <a href="/patients/#{@appointment.patient.id}"> <%=h @appointment.patient.f_name %> <%=h @appointment.patient.l_name%> </a> but it dose not work due to a syntax error, if i click on the href it goes to http://0.0.0.0:3000/patients/#{@appointment.patient.id} thanks 回答1: You can do: <a href="/patients/<%= @appointment.patient.id %>"> But it's generally easier to use link_to : link_to(@appointment.patient.f_name + " " + @appointment.patient.l_name, :controller => 'patients', :action =>

Ruby on Rails: Generate HTML for each file in a folder

问题 I currently have a folder with a list of small *.ogg files that I would like to insert into an html.erb page in my /public folder. The code is within video tags - I want to use Ruby to scan the folder and produce a video snippet for each video it finds in the folder. The code will stay the same between videos, except for the video filename. The resulting page will be a list of playable videos. Any advice would be awesome. 回答1: # assumes the current dir contains the ogg files html = '' Dir

由 烂漫一生 提交于 2019-12-10 03:19:03
问题 I have the following code in my index.html.erb <%= select_tag 'team_id', options_for_select(@teams.map{|team| ["#{team.name} # {team.nick}", team.id] }) %> Where would I add a link_to helper within that block?
