javascript - Get different html with different buttons with AJAX -


i got menu on website

%button.dropdown-button   .current-user{onclick:'showmenu()'}     %img.current-user-image{src:current_user.picture_url}     = current_user     %i.fa.fa-bars{'aria-hidden':true}   .dropdown-content     .menu-option{onclick:'showfilters()'}       filter transactions       %i.fa.fa-paper-plane{'aria-hidden':true}     .transaction-filters       .filter-option         transactions         %i.fa.fa-square-o     %a{href:'#'}       .menu-option         balance history         %i.fa.fa-history{'aria-hidden':true}     %a{href:destroy_user_session_path}       .menu-option         sign out         %i.fa.fa-sign-out{'aria-hidden':true}

and got timeline transactions

.timeline-container   - @transactions.each |transaction|     .transaction-container       .transaction-header-container         .transaction-kudos-container           = "+#{transaction.amount}"           %span.currency             ₭         .transaction-avatar-container           %div             = image_tag transaction.receiver_image, class:'avatar'       .transaction-body-container         .transaction-content           %span             = "#{transaction.sender.name}:"           %span.highlighted             = "+#{transaction.amount} ₭"           %span                       %span.highlighted             = transaction.receiver_name_feed           %span                       %span.highlighted             = transaction.activity_name_feed       %div         -#%button#like-button         -#          %span.post-time-stamp           = "#{distance_of_time_in_words(datetime.now, transaction.created_at)} ago"   = paginate @transactions

they both rendered on index.html.haml

so when click div .filter-option.sent want change code change 

- @transactions.each |transaction|

to 

- @all_transactions.each |transaction|

to filter out transactions of current user without reloading page.

these variables defined in controller

@transactions = transaction.order('created_at desc').page(params[:page]).per(20) @all_transactions = transaction.all_for_user(current_user)

with in model method all_for_user

def self.all_for_user(user)     transaction.where(sender: user).or(transaction.where(receiver: user)).order('created_at desc').page.per(20) end

i tried lot of things ajax nothing seems please me. can me?

so if you'd replace @transactions list ajax need few things..

1) move @transactions block partial takes local variable.

#transactions-wrapper   = render partial: 'transactions/list', locals: {transactions: @transactions}

2) create link submits route, hits controller action #js ('data-remote': true ) ( or write javascript function triggers $.ajax request: https://www.w3schools.com/jquery/ajax_ajax.asp

%a.transaction-filter{href: "/transactions/#{transaction_type}", 'data-remote': true}

or ex..

%a.study{href: "/transactions/recent", 'data-remote': true} %a.study{href: "/transactions/past", 'data-remote': true}

3) define route

get '/transactions/:type' => 'transactions#filter'

4) re-assign variable based on filter, , re-render partial new data in filter.js.erb file thats in view directory -> app/views/transactions

def filter   @filtered_transactions = transactions.where(type: params[:type] ).order('created_at desc')    respond_to |format|     format.html     format.js { render :action => 'filter.js.erb', :layout => false}   end end 
$("#transactions-wrapper").html("<%= j render(:partial => 'transactions/list'', :locals => { transactions: @filtered_transactions } ) %>"); alert('transactions have been filtered, yo')

let me know if makes sense! except please don't javascript alert @ end ;)

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -
