I have several static pages (About, Contact, Help) that are mapped in the routes.rb file like this:
get 'about', to: 'static#about', as: 'about'
get 'contact', to: 'static#contact', as: 'contact'
get 'help', to: 'static#help', as: 'help'
They are accessed in the layout partial, _footer.html.erb from this code:
<%= link_to "About", 'about_path', :class => '' %>
<%= link_to "Contact", 'contact_path', :class => '' %>
<%= link_to "Help", 'help_path', :class => '' %>
Everything works fine until I click on the footer links while I'm in a nested route like /users/current/edit (where I might edit my user-profile). For example, when I click on the ABOUT link at the bottom of the page, I would expect to be taken directly to the static#about route at about_path.
However, I am getting an ActionController exception (in development) and a page not found in production. It's trying to map to /users/current/about_path.
Any ideas on how to fix this?
See Thorin's answer. Remove the quotes around the path method call.

When trying to use user authentication I get the following error: "NoMethodError in Viewer#show". And it addresses the error to <%= #page.body.html_safe%> in app/views/viewer/show.html.erb:1:in '_app_views_viewer_show_html_erb__685858346_34780128', which is only one line code by now.
But, when I call login page on browser address bar like: :3000/session/new, it comes Up. Which is not happening with :3000/session/destroy.
It seems that something related to the route is not working properly because, on the other hand, when I call a page on views/layouts/application.htm.erb like <li><%= link_to 'Home', {:controller => 'viewer', :action => 'show', :name => 'home'} %></li> it works, and if I switch to <li><%= link_to 'Home', view_page_path('home') %></li> it gives a similar error.
How can I solve that?
Your use of view_page_path('home') assumes that there is a named path view_page. Changing
get "/:name" => 'viewer#show'
to
get '/:name' => 'viewer#show', :as => :view_page
should fix that.
Secondly when using route helpers with named parameters you need to specify the name so Rails knows what parameters should be used. Change view_page_path('home') to view_page_path(:name => 'home').
And finally a NoMethodError for <%= #page.body.html_safe%> suggests to me that either #page or #page.body is nil.
I have a property search page (:controller => 'properties', :action => 'index') that consists of a right sidebar that has a search form which displays the search results below the form. When the user clicks on a property in the right sidebar I want to display the details of that property in the main area of the index page on the left.
Right sidebar is a partial called properties/_property.html.erb:
<%= form_tag properties_path, :method => 'get' do %>
<%= text_field_tag 'location', (params[:location]) %>
<%= select_tag(:max, options_for_select([['No Max', ""], ['$100,000', 100000], ['$200,000', 200000], etc %>
more search fields for baths beds etc
<%= submit_tag "Search", :name => nil %>
<% end %>
<% #properties.each do |property| %>
<%= link_to([property.Address,property.City].join(", "), {:action => 'show', :id => property.id}) %>
<li><strong><%= number_to_currency(property.Price, :precision => 0) %></strong></li>
etc etc
<% end %>
The only way I know how to show the property details is with the 'show' action, but that takes the user to a new page, for example localhost:3000/properties/1865. I've made the 'show' view with the same layout as the 'index' view and have made the right sidebar a partial (properties/_property.html.erb) which appears on both 'show' and 'index' so when the user clicks on a property in the right sidebar and goes to localhost:3000/properties/1865 the property details are displayed correctly in the main area and the right sidebar is on the right.
But because localhost:3000/properties/1865 is a different page than localhost:3000/properties/index the search form in the right sidebar has forgotten it's parameters which means the list of search results in the right sidebar has changed back to the default list of all properties.
How can I display the 'show' action within a partial on the index page so the user's search parameters are remembered by the form in the right sidebar? Or if I have to go to the 'show' page how can I make the right sidebar stay exactly as it is?
Any ideas greatly appreciated, just a suggestion in the right direction would be good, have spent all day trying to figure it out and have got nowhere, thanks
I have made the show view with the same layout as the index view and
have made the right sidebar a partial (properties/_property.html.erb)
which appears on both show and index.
Yes but this will only get you a similar layout for both the pages. You want the list to persist between different requests.
You basically have two options. use session to remember the list which I wont recommend.
Other is you use form :remote => true or ajax and update the page partially.
EDIT:
What version of rails you are using? Do u have jquery loaded in your application?
Follow this SO POST.
You might have to change your show action a bit.
respond_to do |format|
format.js {render :partial => 'property_details' ,:layout => false}
format.html
end
Create a partial for property details and just put body content here.
And link will look like
<%= link_to "link name", {:action => :show, :id => item_id}, :remote => true ,:html => {:class => 'links_product'} %>
Also to update the view you may use(make sure you have rails.js in your page):
$(document).ready(
function(){
$("a.links_product").bind("ajax:success",
function(evt, data, status, xhr){
$("#response").html(data); // in case data is html. (_*.html.erb)
}).bind("ajax:error", function(evt, xhr, status, error){
console.log('server error' + error );
});
});
Have a div with id response or any valid id. Done!
I've ran into a weird problem in Rails. When I try and submit a search query with the following form on my Uploads controller:
<%= form_tag ({:controller => "uploads", :action => 'find_uploads'}), :method => "get" do %>
<%=h text_field_tag :search, params[:search], :id => 'search_field' %>
<br />
<%= submit_tag "Search", :style=>"display:inline;" %>
<% end %>
I get redirected to the following url and error page:
/uploads/find_uploads?utf8=✓&search=bot&commit=Search
ActiveRecord::RecordNotFound in UploadsController#show
Couldn't find Upload with id=0
My find_uploads route: get 'uploads/find_uploads' => "uploads#find_uploads"
And when I did I rake routes this is what I got:
uploads_find_uploads GET /uploads/find_uploads(.:format) {:controller=>"uploads", :action=>"find_uploads"}
Everything seems to be in order... not sure why it's not working out as expected. For debugging purposes I dropped breakpoints in both my find_uploads and show actions and neither of them were reached so this error message must be lying to me as the UploadsController show action is never called!
This form is being rendered on my index page if it counts for anything.
I think it's taking find_uploads for an id.
Declare your routes like that:
resources :uploads do
collection do
get :find_uploads
end
end
ps: currently, when you do rake routes, /uploads/find_uploads is after /uploads/:id right?
In my Rails 3 app I have a link_to that takes the User from their profile page to the settings page. The settings page contains a form :partial for editing a profile. What I'd like to do is have the link_to in the Profile take the User to an anchor in the form partial. I've given it a go but am having trouble.
As my link_to I have:
<%= link_to('Visit the info section', settings_path, {:anchor => 'info'}) %>
Within settings_path is <%= render :partial => 'profiles/edit_settings_form' %>
Within that partial is:
<div class="infoBlock" anchor="#info">
</div>
I have a route for settings that I thought was causing the error:
match "/settings" => "settings#show", :as => 'settings'
I tried adding another match for the anchor to "profiles#edit_settings_form" but it didn't work. Any ideas?
<div class="infoBlock" anchor="#info">
is not proper way to do an anchor to a page. Correct syntax is something similar:
<a name="anchor"></a>
Now when you got to page with pagename#anchor, it redirects you to that block. For example:
<%= link_to "Block in home", :action => "home", :anchor => "anchor" %>
I am very new to ROR and I love it so far as I develop my first app. I have a question related to my application template as I apply formatting to the nav menu.
Is it possible to check if a url path matches the root:to path set in config.rb? I have a helper method that returns the string "current" which adds the css class style to highlight the selected menu item. The helper method works fine as long as I'm not at the homepage. When I my url is www.localhost:3000/ the css current class is not applied to the Products link since the request_uri = "/" which doesn't equal "/products". I would like the css class "current" applied to the Products menu item when I'm on the homepage.
Is there any conditional logic I can use to get the root:to path and check if it matches the is_current's parameter path?
Here's my code:
routes.rb root:to setto point to the products index view
root :to => 'products#index'
application.html.erb
<%= link_to 'Products', products_path, :class => is_current(products_path) %>
<%= link_to 'Reports', reports_path , :class => is_current(reports_path) %>
application_helper.rb
def is_current(path)
if request.request_uri == path
return 'current'
end
end
Any help would be greatly appreciated.
Thanks,
bkasen
Would this work for you?
if current_page? root_path
for more info: http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-current_page%3F
If I read correctly, you want "onlink" css applied? so that when the user is on the home page, the home icon is a different color or something. If so then apply this in your header partial or where ever:
<li><%= link_to_unless_current "Home", root_path, :class => "navLinks" do link_to "Home", root_path, :class => "navLinks", :id => "onlink" end %></li>
I know this is an old question, but it may prove useful to someone else :)
