  ruby-on-rails link-to
  In my Rails app, I was having issues with rendering a link_to because, for some reason, a new line is added through my link_to. For example, when I try to create the link with:<% byline = render :partial => “projects/author_byline”, :locals => {:project => image.project, :source=>”home”} %> <script type=”text/javascript”>console.log(‘byline : <%= byline %>’); </script>I would get this in the console:console.log(‘byline : <a href=”/users/scientiffic” clas

  Here’s what the default scaffolding generates:<%= link_to ‘Delete’, admin_user, method: :delete, data: { confirm: ‘Are you sure you want to delete?’ } %>I want to create a helper method so that I can call a remove_link(admin_user) and have it behave the same way:def remove_link(item) link_to item, method: :delete, :data { confirm: ‘Esta seguro que quiere eliminar este registro?’ } do”#{content_tag :i, nil, class: ‘icon-remove-sign’}”.html_safeendendBut I’m getting this error:SyntaxError

  I tried doing several searches for this and couldn’t find anything, so hopefully I’m not posting a duplicate.So, the API Dock’s link_to docs has this as a signature:link_to(options = {}, html_options = {}) do# name endSeemed kind of interesting so I decided to give this a shot:<%= link_to { action: ‘win’, game_id: @games[0].id }, { :method => :post } do %><div><%= image_tag @games[0].img_url %><%= @games[0].name %></div> <% end %>This resulted in a syntax e

  ruby-on-rails params link-to
  I have a view that uses link_to to pass parameters to a controller. The url is a variable. Something is not working. I’d appreciate any clues. Thanks!<% url1 = dialogs_path(@dialogId) %> <%= url1 %> <%= link_to “Go!”, url1(:uid1 => @uid1, :uid2 => @uid2), :id => “my_link” %>url1 displays correctly. However, executing link_to crashes.

  jquery ruby-on-rails ruby ruby-on-rails-3 link-to
  I am using Ruby on Rails 3.0.7 and jQuery 1.6.1 and I am binding an AJAX click event to a link_to HTML output as in the following example:link_to ‘Link name’, ‘#’, :id => ‘link_css_id’As you can see I set the URL to ‘#’. Doing that when I click on the link the current view will be moved at the top of the page, as well. Since I don’t like this behaviour, I set nothing (that is, nil or ”) for the URL parameter, but on clicking on the link I get an alert message “error” that immediately after d

  ruby-on-rails helper link-to
  I’m new to rails and am having what I think is a very simple issue.I have a list of “tasks”. When you click on a task, I want to update its row in the database to mark it as complete (changing the “status” column form 0 to 1).Here is what the links look like in my view:<td><%= link_to t.name, change_task_status_path(:id => t.id) %>And here is what’s in my tasks_controller.rb:def change_task_status@t = Task.find_by_id(params[:id])@t.status = ‘1’ # 1 = [email protected] :nothing

  ruby-on-rails ruby link-to actioncontroller
  First of all, pretty new to Rails. I’ve been following a tutorial on using the ‘link_to’ command – basically, I have some links with text ‘About Us’, ‘FAQ’, ‘Contact Us’, and I want them to link to their respective pages.Following the tutorial, the code in my contact_us.html.erb file goes like this:<%= link_to “About Us”, {:controller => ‘static_pages’, :action => ‘about_us’} %>My controller is called static_pages_controller.rb and I have an about_us method in that file, with no code

  What am I doing wrong here?This seems to work fine earlier in my code:[email protected] do |img|-link_to eval(params[:action] + ‘_image_path(img)’) do=image_tag img.image.url(:thumbnail)But this is not working. Why not?-link_to eval(params[:action] + ‘_image_path(@featured_image)’) do=image_tag @featured_image.image.url(:display)I am seeing “Uncaught TypeError: Cannot call method ‘bind’ of undefined” There seems to be an issue with calling _image_path(@featured_image)’. 🙁

  I need to pass a notice to a view from controller, and I want if can to create some link also to the notice.My controller:format.html { redirect_to purchase_order_headers_path, notice: ‘PO already has RR with RR ID: ‘ + rr.rr_id + ‘, void RR first.’ }Is there any way so I can do it so the [rr.rr_id] will become a link so when the user click on it will go to it’s page? Since link_to will return error “undefined method” if put on controller.Thanks.
