I want to pass a parameter using link_to. (Also I am trying to use Bootstrap tab)
ilban.html.erb
<%= link_to '일반공지', '#home', { 'data-toggle' => 'tab', 'aria-controls'=>'home', 'role'=>'tab', :where => 1 } %>
cpu_controller.rb
#where = params[:where]
This code doesn't get where as an parameter. How can I fix it?
I have not tested it, but it should pass the params that you want.
link_to "Search", searches_path(:where => 1, :when => "Today"), { 'data-toggle' => 'tab', 'aria-controls'=>'home', 'role'=>'tab' }
Controller:
#where = params[:where]
In Rails 5, try this syntax for link_to
link_to 'Show', view_path(:id => view.id), { 'data-toggle' => 'tab', 'aria-controls'=>'home', 'role'=>'tab' }
In the place of view path you can edit with your controller path and pass the valid id that you need to link.
Or, try this syntax also to pass params
<%= link_to "Add car", {:controller => "car", :action => "add_car", :car => car.id }%>
And add in your controller
#car = Car.find(params[:car])

I have the following two buttons in my index.html.haml:
= button_to t('payer_contracts.new_global_payer_contract'), new_payer_contract_path, {:class => 'btn pull-left', :method => 'get'}
= link_to t('payer_contracts.new_bpci_payer_contract'), new_payer_contract_path
As you can see they both go to new_payer_contract_path. How can I make it so that if the first button is clicked, I can send a param such as new_payer_contract_path(new_global_payer_contract) ?
The problem is: in my new.html.haml, both of them are rendering 'global_form'. I want the first button to render global_form and the second button to render 'bpci_form'
Here is the new.html.haml:
- content_for(:title, t('payer_contracts.page_titles.new'))
- content_for :article do
.common-main-container
%h1= t('payer_contracts.new_payer_contract')
= render 'global_form'
In my payer_contracts_controller I have this so far:
def new
#payer_contract = PayerContract.new(
id: '',
contract_name: '',
contract_type: {
id: '',
code_key: '',
display: '',
code_group: ''
},
amount: '',
stoploss_amount: '',
stoploss_reimbursement_percentage: '',
begin_date: '',
end_date: '',
timely_filing_days: '',
payer: ''
)
end
With button_to, you can pass a params hash:
<%= button_to t('payer_contracts.new_global_payer_contract'), new_payer_contract_path, class: 'btn pull-left', method: :get, params: { x: "y" } %>
This creates a hidden_field inside the form that button_to creates, allowing you to pass params[:x] to your next action.
Update
As per your comments, you're getting the params[:x] variable in your controller.
You just have to use this in your ActiveRecord query call:
#view
-if params["x"] == "y"
= render "global_form"
-else
= render "bpci_form"

I've searched all over and I've only found js ways to update a partial or add a partial via JS. I've had no luck with this one. Here is the issue:
I have a list of referrals on a page, the referrals are posted on the index page as partials. The referral box has a reply button and a count of how many replies per referral. Statically I had it working but I'm getting no luck with updating the referral box with the new count and replacing the reply button with an icon. The is getting to the database but I'm screwing something up with the refresh of the box. Help please!
Do I use locals to render the new variables?
Should I remove my if statements from the partial and just use the js.erb file to determine what to show?
Reply controller:
class RepliesController < ApplicationController
respond_to :html, :js
def new
#referral = Referral.find(params[:referral_id])
#reply = #referral.replies.new(:user_id => params[:user_id], :referral_id => params[:referral_id])
if #reply.save
format.html { notice: 'Replied' }
respond_with(#referral, :location => referrals_path)
end
end
end
_referral partial:
.referralBox.cornerShadow{:id => "Referral#{referral.id}"}
- if current_user == referral.user or current_user.role == 'administrator'
= link_to '<i class="icon-pencil icon-large icon-grey" rel="tooltip" title="Edit"></i>'.html_safe, edit_referral_path(referral), class: "referralEdit"

%ul.unstyled.inline

Controller
class FeedEntriesController < ApplicationController
def index
#search = FeedEntry.search(params[:search])
#feed_entries = #search.page(params[:page])
#app_keys = AppKey.all
end
end
My feed_entries/index.html.erb
<%= link_to "Stared", {:controller => "feed_entries", :action => "index", :search => ['is_star = ?', true] }%>
feed_entries table contain is_star:boolean attribute. So, I just want to pass the parameter is_star == true into the params[:search].
But the above code is not working. Please some one help me.
Try
<%= link_to "Stared", {:controller => "feed_entries", :action => "index", :is_star => true } %?
And then you should be able to access in the controller using params[:is_star]
On my index page for my Task model, I want to show a checkbox for every row that corresponds to the boolean field "complete" in my Task database table.
Currently my code gets into the method "Complete", but it does not contain the value of the checkbox that the user just did (i.e. if they just checked the box, it does not pass true to my "Complete" method).
How can i pass the value that the user just performed - either checked or un checked?
/views/tasks/index.html.erb
<% #tasks.each_with_index do |task, i| %>
<tr>
<td><%= check_box_tag 'Complete', task.complete, task.complete, :data => {:remote => true, :url => url_for( :action => 'complete', :id => task.id, :complete => task.complete ), :method => :put}, :class => 'input-large' %></td>
</tr>
<% end %>
/controllers/tasks_controller#complete
# PUT /complete/1
def complete
#task = Task.find(params[:id])
p "inside complete"
p "complete = #{params[:complete]}"
#task.complete =
if #task.update_attributes(params[:task])
p "inside update"
render :text => "success"
else
p "inside error"
end
end
The suggestion from this issue in rails/jquery-ujs github repo worked for me: https://github.com/rails/jquery-ujs/issues/440#issuecomment-197029277
For you it would be:
<%= check_box_tag 'complete', '1', task.complete, {
onchange: "$(this).data('params', 'complete=' + this.checked)",
data: { url: url_for(action: 'complete', id: task.id,), remote: true, method: :patch },
} %>
If you are using jQuery, you can write a click event.
$('.input-large').click(function() {
var checked;
if ($(this).is(':checked')) {
checked = true;
} else {
checked = false;
}
$.ajax({
type: "POST",
url: "/tasks/complete",
data: { id: $(this).data('post-id'), checked: checked }
});
});
As of Rails 4, you should be able to ditch all the JS from the original answer. The code in your question should just work due to jQuery UJS magic.
It turns out that adding remote: true to an input causes jquery-ujs to make it ajax-y in all the nice ways. Thoughtbot's "A Tour of Rails jQuery UJS" briefly touches this (and many other good things available); the "Unobtrusive scripting support for jQuery" page in the jQuery UJS wiki does a thorough job on this as well.
check_box_tag 'complete', task.complete ? 'false' : 'true', task.complete, ...
:url => url_for( :action => 'complete', :id => task.id )
This way in your controller you can get params[:complete].
And you should implement complete.js.erb to rerender checkbox, so next click will send inverse value
Or you can implement js on click event
$('.input-large').on('click', function() {
$.ajax({
type: "PUT",
url: "/tasks/complete/" + $(this).data('post-id')
data: { complete: $(this).is(':checked') }
});
});
and don't forget to place data-post-id param to your checkbox
This bug has me perplexed.
I am displaying a Widget with the last 5 data points and a form for a new data_point. When I try to render both the form and the display partial it fails with a routing error. If I comment out either partial it works fine. So with only the form partial it works, or with only the display partial it works fine with the other.
Three relevant models/controllers: Widget, DataSet and DataPoint. DataPoints is STI so I have different partials to display the different types that match the class name.
When both render :partial => ... are uncommented it looks as if the data_point being passed to the second partial is the same as the data_point being passed to the first partial. It is all nil with only a data_set_id. I tried renaming the local from :data_point to :dp in case it was a name collision.
View, both partials and the routing error shown at the bottom.
Is there a limitation on passing :locals to partials when you are trying to render more than one partial in a view?

Try running rake routes for more information on available routes.
The problem stems from the fact that the form is building a new element that isn't saved, and last is returning that unsaved element.
Simple solution, replace .last(5) with .find( :all, order: 'id desc', limit: 5 )
