In my Rails3 app I have:
<%= link_to "Sign out", destroy_user_session_path %>
I know how to localize text, but how to localize link text? I defined "sign_out" in tried:
<%= link_to t( sign_out ), destroy_user_session_path %>
But it generates an error:
undefined local variable or method `sign_out'
What is the correct syntax?
PS: It is even more basic than this question, but I could not find any answer.
<%= link_to t('sign_out'), destroy_user_session_path %>
And you must define the key sign_out: in your local yml file after
How about link_to t("sign_out"), destroy_user_session_path?
<%= link_to t(:sign_out), destroy_user_session_path %>
or
<%= link_to t('sign_out'), destroy_user_session_path %>
You can check other details here.

I have a Rails app that is running fine on Rails 3.x and ActiveAdmin 0.6.6. However I want to upgrade it to Rails 5 and ActiveAdmin 1.x. I started the upgrade process first upgrading from 3.x to 4.x and then to 5x, and with ActiveAdmin I tested with 1.0.0 and now I'm using the master from Github.
Everything worked fine with the App in both Rails versions and ActiveAdmin but the ActiveAdmin forms that are in a partial.
The problem is the following:
I have a file app/admin/menu.rb whose has a partial views/admin/menus/_form.html.erb.
The partial contains the form of the Menu.
This is the contents of the partial (views/admin/menus/_form.html.erb):
<%= semantic_form_for [:admin, #menu], builder: ActiveAdmin::FormBuilder do |f| %>
<% f.inputs 'Campos Menu' do %>
<% f.input :project if current_admin_user.admin? %>
<% f.input :title %>
<% f.input :title_en %>
<% f.input :item %>
<% f.input :icon, as: :file %>
<% end %>
<% f.inputs 'Submenus' do %>
<% f.has_many :submenus, heading: '' do |fa| %>
<% fa.input :title, as: :string %>
<% fa.input :title_en, as: :string %>
<% fa.input :kind, as: :select, collection: Submenu.kind_collection %>
<% fa.input :items_as, as: :select, collection: Submenu.items_as_collection %>
<% end %>
<% end %>
<% f.actions do %>
<% f.action :submit %>
<% end %>
<% end %>
The render result of this file is only the 'actions' buttons, in this case the 'submit' button. The interesting thing is that if I remove the <% f.actions do %>... from the partial then the <% f.inputs 'Submenus' do %> gets rendered and the same if I remove the later. In other others is being rendered on the last block that contains an end.
The same behaviour is being observed on Rails 4.x and 5.x (except Rails 5.1.x which I didn't tested).
If I move the form from the partial to the app/admin/menu.rb it gets rendered properly. This could be a solution for me however I have others forms that make use of JQuery for fields manipulation and other stuff on the front end.
As I said before, all these forms partials were working properly on Rails 3.x and ActiveAdmin 0.6.6.
Anyone knows what's the problem?
DISCLAIMER: I'm not a Rails or ActiveAdmin expert, so bear with me if is a silly mistake related to this issue.
Yes, it's activeadmin#3486 I'm glad you figured out the workaround. I'm curious if this Arbre branch fixes it for you. Glad to see people still upgrading, I'll do what I can to help.
The solution that I found was to put a = for the <% f.input(s) %> on the partial. Having something like this <%= f.inputs ... %> instead of this <% f.inputs ... %> solves the problem.
I have a rails app where I can create and edit records. I've created a form to enter data which works fine when I use the new/create actions. It will create a record no problem. But when I hit the edit action it gives me an undefined method 'model_name' for NilClass:Class.
I'm not sure what this means. Can someone give me a hand?
Form:
<%= form_for(#patient) do |f| %>
<%= f.label :Patient_Last_Name %>
<%= f.text_field :patient_last %>
<%= f.label :Patient_First_Name %>
<%= f.text_field :patient_first %>
<%= f.label :Patient_DOB %>
<%= f.date_select :patient_dob %>
<%= f.label :Primary_Diagnosis %>
<%= f.collection_select(:diagnosis_id, Diagnosis.all, :id, :diagnosis_name)%></br>
<%= f.label :Primary_Physician %>
<%= f.collection_select(:physician_id, Physician.all, :id, :physician_name)%></br>
<%= f.button :submit %>
<% end %>
View Code:
<td><%= link_to 'Edit', edit_patient_path(patient), :class => 'btn btn-close btn-mini'%></td>
Controller Code:
def edit
#patient = Patient.find(params[:id])
end
Edit view:
<%= render 'form' %>
When I remove the partial render from the form, the URL will go to the correct route/url. But I keep getting that error when the form partial is rendered.
There was an extra end statement in my controller which was cutting off half of the class which included the edit action. This was not allowing me to use the edit action. Once this typo was fixed things started working normally.
Sorry for the confusion.
I am attempting to use resources to auto generate routes for my resource. The namespace is admin and the resource is author. The following code seems to work for most instances.
namespace :admin do
resources :author
end
When I run
rake routes
I get the following
admin_author_index GET /admin/author(.:format) admin/author#index
POST /admin/author(.:format) admin/author#create
new_admin_author GET /admin/author/new(.:format) admin/author#new
edit_admin_author GET /admin/author/:id/edit(.:format) admin/author#edit
admin_author GET /admin/author/:id(.:format) admin/author#show
PUT /admin/author/:id(.:format) admin/author#update
DELETE /admin/author/:id(.:format) admin/author#destroy
From what I can tell I am expecting the named paths to have a
_path
at the end. I am rather green at this. I have searched and searched but I could just be using the wrong terms to find the answer. Any help is appreciated. Thanks!
-edit- I should add that
<%= form_for [:admin, #author] do |f| %>
<%= f.label :first_name %>
<%= f.text_field :first_name %>
<%= f.label :last_name %>
<%= f.text_field :last_name %>
<%= f.submit %>
<% end %>
Gives me errors saying it can not find admin_author_path
You can append either _path or _url to these. Basically everything looks good.
So for example
admin_author_index GET /admin/author(.:format) admin/author#index
the helper method can be admin_author_index_path or admin_author_index_url. These helpers can be used in controllers and views to point to a controller/action or url. Read this link http://guides.rubyonrails.org/routing.html to understand more.
No. The route name does not have the _path suffix.
Refer to Rails routing from inside in for more information. It explains routing in great detail.
I am having a weird issue with Devise. I have lists with tasks on them. When you delete a task all of the sudden I get a template error having to do with the User.
It seems like the delete method causes the session to logout and therefore can't find the User when trying to load the template.
I have no idea why this is happening:
_task.html
<div class="tasks">
<%= div_for task do %>
<%= link_to 'Delete', task_path(task), :method => :delete, :class => "delete", :remote => true %> | <%= content_tag(:div, task.task, :class => "task-body") %>
<% end %>
</div>
destroy.js.erb
$("#task_<%= #task.id %>").fadeOut();
ERROR AFTER RELOADING PAGE, THIS IS FOR THE ACCOUNT, LOGOUT ETC in HEADER
No route matches {:action=>"show", :controller=>"users"}
Extracted source (around line #5):
2: <div id ="login">
3: <ul>
4: <li><%= link_to "Sign out", destroy_user_session_path %></li>
5: <li><%= link_to "Account", user_path(current_user) %></li>
6: <li><%= link_to "Things", user_things_path(current_user) %></li>
7:
8: </ul>
Thanks in advance!
After a little more searching I found the answer here on stackoverflow, so credit should go to justsee from this previous question
The request will not include the required CSRF data, and as of
Rails 3.0.4 the session is silently reset instead of throwing an
ActionController::InvalidAuthenticityToken error.
To fix this include the following in your layout:
<%= javascript_include_tag :defaults %>
<%= csrf_meta_tag %>
I am using Rails 3.0, Ruby 1.9.2 and the Plataformatec simple_form gem. This code works with a form_for but not simple_form_for:
<%= simple_form_for(#provider) do |f| %>
<% Car.all.each do |c| %>
<div>
<%= check_box_tag :car_ids, c.id, #store.cars.include?(c), :name => 'store[car_ids][]' %>
$<%= c.cost %> | <%= c.description %>
</div>
<% end %>
<div class="actions">
<%= f.submit "New" %>
</div>
<% end %>
How do I get it to work with simple_form_for?
Thanks in advance!
You can't use simple_form right the same way as form_for.
For example ther is no any check_box_tag method in simple_form gem. There is ONLY inuput fields that you can specify with :as option. So your check_box_tag will be converted to
f.input car_ids, ..., :as => :check_box

The problem was in the controller code.
In the "new" controller action I can't simply perform:
#provider = Provider.new(params[:provider])
as one would normally.
Instead I have to process each parameter separately:
#provider.location = params[:provider][:location]
etc...
For the Car check boxes, I add each car_id from the car_ids parameter to the "has_many" cars model association one at a time:
car_ids = params[:provider][:car_ids]
car_ids.each do |cid|
#provider.cars << Car.find(cid)
end
Then I can call:
#provider.save!
And it saves correctly (my initial problem was that it wasn't saving the selected Cars).
For some reason, I was able to figure this out only after posting the question here. Funny how that works.
Thanks all for your replies!
