Upon checking submit I get Routing Error: uninitialized constant DuelersController
duels/show.html.erb
The loser(s) will <%= #duel.consequence %><br><br>
If everyone succeeds they will <%= #duel.reward %>
<%= form_for #dueler do |f| %>
Accept? <%= f.check_box :accept %>
<%= f.submit %>
<% end %>
There is no DuelersController only DuelsController
def show
#dueler = Dueler.find_by(user_id: current_user.id)
respond_with(#duel)
end
def set_duel
#duel = Duel.find(params[:id])
end
Once a user clicks submit how can I redirect the user back to the show page?
Dueler.last
id: 20,
user_id: 78,
challenge_id: 178,
duel_id: 13,
accept: nil> # For example redirect back to duels/13 with accept: true
Sorry, I was distracted. I think your problem is actually another, you have to explicitly specify the controller and action here.
On a side note, maybe you'll have to change the way you fetch your parameters on the set_duel action (I don't remember if rails sets the id automatically), anyway:
#Assuming you want to call set_duel upon submission
<%= form_for #dueler, :url => { :controller => "duel", :action => "set_duel" }, :html => {:method => :post} do |f| %>
Accept? <%= f.check_box :accept %>
<%= f.submit %>
<% end %>

I'm implementing the website. I got a problem for a search form. I upload my code, and what i want to ask is how to set the search 'path' through 'index' and 'historical' on homes_controller
Below, my code:
app/controllers/homes_controller
def index
#homes = Home.where(:category => 1).reverse
end
def historical
#homes = Home.where(:category => 2).reverse
end
app/views/layouts/application.html.erb
Below, this code is temporary code for now. I should change it.
<%= form_tag(homes_path, :method => 'get', id: "search-form" do %>
<%= text_field_tag :search, params[:search], placeholder: "검색" %>
<%= submit_tag "검색", :name => nil %>
<% end %>
Am not sure what you are supposed to do here
But as per the question - I can give a solution to your problem
Keep an instance variable in your controller actions - like this
app/controllers/homes_controller
def index
#homes = Home.where(:category => 1).reverse
#search_path = "path you want to give"
end
def historical
#homes = Home.where(:category => 2).reverse
#search_path = "path you want to give"
end
and in your layout you can use it like this
app/views/layouts/application.html.erb
<%= #search_path.present? %>
<%= form_tag(#search_path, :method => 'get', id: "search-form" do %>
<%= text_field_tag :search, params[:search], placeholder: "검색" %>
<%= submit_tag "검색", :name => nil %>
<% end %>
<% end %>
I need to get an integer(#integer) from the form in my root_path, do multiplication (#integer*45) and display the result on the same page. How can I do it without any models in my application?
Please, share your best practice. Thank you!
I was trying to do next:
CalculatorsController
def calculation
#integer = params[:integer]
#result = #integer*45
end
def result
end
root.rb
root :to => 'calculators#result'
resources :calculators, :collection=>{:result => :get, :calculation => :post}
calculators/result.html.erb
<% form_tag root_path, :html => {:method => :post} do %>
<%= label_tag 'integer' %>
<%= text_field_tag :integer %>
<div><%= submit_tag 'OK' %></div>
<% end %>
I'll do it with ajax, so there is no need for page refresh:
First, update the routes, for your example you only need two routes, one get (or root) and one post.
routes.rb:
Rails.application.routes.draw do
root 'calculators#result'
post 'calculators/calculation'
end
Next, update your view:
Change the url in your form_tag where the data will be sent (to calculation action instead of result).
Add remote: true option to enable ajax.
Add a tag where you will display your result.
result.html.erb:
<% form_tag calculators_calculation_url, remote: true do %>
<%= label_tag 'integer' %>
<%= text_field_tag :integer %>
<div><%= submit_tag 'OK' %></div>
<% end %>
<div id="total"></div>
And create a view for calculation action, but since you are using ajax, you will create it as js.erb and include the required javascript (or jQuery) to update your view (i'm using jQuery in the example).
calculation.js.erb:
$('#total').html('<%= #result %>')
Now when you click submit, your form will be sent to calculation action and will update the div with #result.
Just add the field to your form...
<% form_tag root_path, :html => {:method => :post} do %>
<%= label_tag 'integer' %>
<%= text_field_tag(:integer, #integer) %>
<% if #result.present? %>
<br>
Result is: <%= #result %>
<br/>
<% end %>
<div><%= submit_tag 'OK' %></div>
<% end %>
And then render result in your calculate...
def calculation
#integer = params[:integer].to_i
#result = #integer*45
render :result
end
Your result view (result.html.erb) is getting its data from the result method, not calculation. Update your controller as follows:
def calculation
#integer = params[:integer]
end
def result
#result = #integer*45
end
You then need a tag to display your result in the view, something like:
<p> <%= #result %> </p>
I have a modal that will serve as a disclaimer in my app and I need the link at the bottom of the modal that says "agree & continue" to toggle a boolean and input the time that the boolean was toggled. I have created the button as a form with hidden links but I cant seem to see how to make it submit the form AND redirect to the path i specify. Here is my link_to code now.
<% if current_user.user_record.blank? %>
<%= form_for :user do |f| %>
<% f.hidden_field :disclosure_acceptance, :value => true %>
<% f.hidden_field :disclosure_date, :value => Time.now %>
<%= link_to("Agree & Continue", user_steps_path(current_user), class: "btn btn-primary") %>
<% end %>
<% end %>
First, create a new method in your user_records_controller or at whichever controller action the form is displayed at:
def new
#user_record = current_user.build_user_record
end
Put this in your view:
<% if current_user.user_record.blank? %>
<%= form_for #user_record do |f| %>
<%= f.hidden_field :disclosure_acceptance, :value => true %>
<%= f.hidden_field :disclosure_date, :value => Time.now %>
<%=f.submit "Agree & Continue", class: "btn btn-primary") %>
<% end %>
<% end %>
Make a create action for the user_record that looks like this:
def create
#user_record = current_user.build_user_record(permitted_params)
if #user_record.save
redirect_to user_steps_path(current_user)
else
render :new
end
end
private
def permitted_params
params.require(:user_record).permit(:disclosure_acceptance , :disclosure_date) #etc
end
UPDATE
If you directly want to jump to the 'create' action, you can make your configuration like this:
Add a custom action to your routes:
post 'rate/:article_id' => 'user_records#create' :as => :create_user_record
#or whichever controller/action you wish
You should update the route on your form:
= form_tag create_user_record_path, :method=>'post' do
#etc
In order to create a user_record from the controller, you need to change things a little bit:
def create
current_user.user_record.create(:user_id => current_user.id, :disclosure_acceptance => params[:disclosure_acceptance] , :disclosure_date => params[:disclosure_date])
if current_user.user_record.save
#etc
end
I have a form in Rails
<div class="page-header">
<h3>Create Blah</h3>
</div>
<%= simple_form_for #blah do |f| %>
<%= f.input :id %>
<%= f.input :name %>
<%= f.input :pho %>
<%= f.input :fun %>
<%= f.submit :class => 'btn btn-primary' %>
<% end %>
<br>
When I click the submit button, where does the code attempt to go? Does it call the create method for blah_controller.rb? Because currently, I get a routing error
Routing Error
uninitialized constant BlahsController
Here is the BlahController#create method:
def create
authorize! :create, :blahs
#blah = Blah.new(params[:blah])
if #blah.save
redirect_to admin_blah_path(#blah), :notice => 'New blah created!'
else
render :new
end
end
In my rake routes, I have
admin_blahs GET /admin/blahs(.:format) admin/blahs#index
POST /admin/blahs(.:format) admin/blahs#create
new_admin_blah GET /admin/blahs/new(.:format) admin/blahs#new
edit_admin_blah GET /admin/blahs/:id/edit(.:format) admin/blahs#edit
admin_blah GET /admin/blahs/:id(.:format) admin/blahs#show
PUT /admin/blahs/:id(.:format) admin/blahs#update
DELETE /admin/blahs/:id(.:format) admin/blahs#destroy
It looks like your BlahsController is a namespaced controller, living under the Admin module (i.e., its fully-qualified name is Admin::BlahsController). If so, when constructing forms you must also provide the :admin namespace, using something like the following:
<%= simple_form_for [:admin, #blah] do |f| %>
See the Rails Guide to Form Helpers, under the "Dealing with Namespaces" section.
I've got an admin section setup, but am having trouble getting the "update" route to work.
Getting error when hitting "update" via the edit view:
"No action responded to 2."
For some reason the route is responding to the :id as the :action.
Parameters:
Parameters: {"commit"=>"Update", "action"=>"2", "_method"=>"put", "admin"=>{"ended_at(1i)"=>"2010", "ended_at(2i)"=>"8", "ended_at(3i)"=>"22"}, "id"=>"edit", "controller"=>"admin/subscriptions"}
The edit view uri:
/admin/subscriptions/2/edit
Edit view:
<% form_for :admin, #subscription, :html => {:method => :put} do |f| %>
<p>
<%= f.label :ended_at %><br />
<%= f.date_select :ended_at %>
</p>
<p>
<%= f.submit 'Update' %>
</p>
<% end %>
Route:
map.namespace :admin do |admin|
admin.resources :subscriptions
end
I assume I need to do something differently in the form_for method or maybe the routes, but everything I've tried isn't working.
Thanks for the help!!
It should be this:
<% form_for [:admin, #subscription] do |f| %>
By putting :admin and #subscription in square-brackets, this makes it into an array which is passed as the first argument to form_for. The benefit of this is if #subscription is a pre-existing record (as-in, one found by find, not created with new) then Rails will know to set the form method to PUT.
This works:
<% form_for :admin, #subscription, :html => {:method => :put}, :url => { :action => "update" } do |f| %>
Seems verbose though. Any better ideas?
Try
- form_for :subscription, #subscription do |f|
