Using AJAX to search, sort, and paginate in Rails 4

由 浪尽此生 提交于 2019-12-07 16:38:03
问题 I'm trying to do a real-time search in a Rails 4.0.1 application. I used the Railscasts #240 tutorial, but I am not getting the same results as the cast. It seems that my only issue is with the AJAX script, but I don't know why or how. app/views/subproducts/index.html.erb <%= form_tag subproducts_path, :method => 'get', :id => "subproducts_search" do %> <p> <%= text_field_tag :search, params[:search] %> <%= submit_tag "Search", :name => nil %> </p> <div id='subproducts'> <%= render

Using jCrop with cloudinary through rails 4 to crop before creating image

由 做~自己de王妃 提交于 2019-12-07 14:02:58
问题 I've been at this for some time now. I"m using cloudinary to upload photos and am trying to implement a cropping feature using jcrop on a photo create action. After I implemented cloudinary I followed railscasts #182 on Jcrop. I think I'm having problems getting the new cropped parameters (x,y,w,h) back to the uploader before the image is saved. Update: I'm not even getting the values put into the f.text_fields. When I move the cropper around, there should be new values right? Here's a pic of

问题 In the valuations form there is a submit button and a <%= f.submit :private %> button. If private submit is clicked the submitted info will be hidden to other user's who view the profile.

Private messages with Faye and Rails

由 可紊 提交于 2019-12-05 02:06:43
问题 I'm using the faye gem menitioned in the railscast allowing apps to push messages. Problem is it pushes messages to all chat clients that are open. I need them to be private. It's possible to get private messaging with faye but it's url based. For example all messages will be sent to site.com/foo . But, in my model the chat doesn't have a specific url. Because chat is just a collection of messages sent to you by that user. So if you're logged in as adam site.com/messages/eve would allow you
