问题 I configured my application to work on Heroku, but I'm having a problem. In development mode, when I change a part of the CSS and refresh the browser, my CSS doesn't load. I checked the logs, and the application.css doesn't load. I need it to load every time in development mode. Also, my application.js stopped working and I dont know why. development.rb: # Do not compress assets config.assets.compress = false config.assets.precompile += %w( login.css ) # Expands the lines which load the

问题 So the other day I was trying to replicate some of the tests that were being ran by circleci and before some of the commands I called: export RAILS_ENV=test export RACK_ENV=test and now I guess the problem is that I seem to be stuck in test ? Also, I've tried executing those same commands except with each of the vars set to development, yet to no avail. Any ideas? 回答1: try 'unsetting' those env variables. export RAILS_ENV= export RACK_ENV= or try restarting the server to set them back to

问题 I have been facing a weird problem for some time, wherein ActiveRecord queries are not getting logged in the terminal, or in the Rails console (using ActiveRecord::Base.logger = Logger.new(STDOUT) ). This is the exception that I get: Could not log "sql.active_record" event. NameError: undefined local variable or method `s' for # ActiveSupport::Notifications::Event:0x007f9ae02a60c0. I tried out a few things, including reinstalling Rails, but to no avail. Apart from wondering why this is

问题 The URL still shows the id and not the title even after using slug. Code as follows index.html.erb <title>Blog!</title> <h1>List of the Posts</h1> <% @posts.each do |post| %> <%= link_to post.title,:id => post.slug%> <p><%= post.content %></p> <%= link_to "Edit",edit_post_path(post) %> | <%= link_to "Delete",post,:confirm=>"Are you sure ?",:method=>:delete %> <hr /> <% end %> <p><%= link_to "Add a New Post",new_post_path %></p> posts_controller.rb class PostsController < ApplicationController

问题 I have a Rails 3.2.21 app in which I'm using a select helper in a form like so: <%= f.select :phys_option, options_for_select([["N/A", "n/a"], ["No", "no"], ["Yes", "yes"]], :selected => @call.phys_option), :include_blank => true, :required => true, :class => 'select' %> This works with basic functionality for selecting an option, including a blank option, etc. But what doesn't work is the :required => true or the :class => 'select' . I can submit the form even when the selection is blank and

问题 I am having a hard time making the slug from Friendly_id in a nested route when editing and creating? the routes look great for show. http://0.0.0.0:3000/test/tester2 This is the URL I am getting when i try to edit tester2 is: http://0.0.0.0:3000/2/tester2/edit What i would like to see is: http://0.0.0.0:3000/test/tester2/edit Here is my code. team.rb class Team < ActiveRecord::Base extend FriendlyId friendly_id :name, use: :slugged has_many :videos ... end video.rb class Video < ActiveRecord

问题 Rails provides label references for associations in fixtures like this: ### in pirates.yml reginald: name: Reginald the Pirate monkey: george ### in monkeys.yml george: name: George the Monkey pirate: reginald This works great for not-namedspaced models, but I'm using namespaces, and so Rails gets confused, and want to insert the labels instead of the label references. Any workaround or fix known? 回答1: Fixtures.identify seems to be the only solution, not really beautiful but better than ids.

问题 I'm trying to attach CSV files to a Rails3 model using paperclip 4.1.1, but I'm having trouble getting the content-type as reported by S3 to be text/csv (instead I am getting text/plain ). When I subsequently download the file from S3, the extension is getting changed to match the content-type instead of preserving the original extension (so test.csv is downloaded as test.txt). From what I can see, when you upload a file, the FileAdapter will cache the content-type on creation with whatever
