I am trying to make the vote total editable from a JSon parsed API. I have the following in my rosters controller:

def index

@rosters = HTTParty.get('https:api', :headers =>{'Content_Type' => 'application/json'})

 @allrosters = Roster.all

 @allrostershash = {}

 @allrosters.each do |roster|

  image_url = roster['image_url']

  @allrostershash[ image_url ] = roster 

 end

 @rosters.each do |roster|

  img_url = roster['image_url']

  unless @allrostershash[img_url]

    Roster.create(roster)

 end

end

end

  def count_vote

    roster_id = params[:id]

    roster = Roster.find_by(roster_id)

    newvote = roster.vote + 1

    if roster.update({vote: newvote})

      redirect_to rosters_path

    end

  end

Roster is the name of my class above. In my rails views I have the following:

<% @rosters.each do |roster| %>

  <div class='each'>

    <%= image_tag(roster['image_url'], class: 'image') %>

    <%= hidden_field_tag(roster['id']) %>

    <p class='name'> <%= roster['name'] %> </p>

    <p class='title'> <%= roster['title'] %> </p>

    <p> <%= roster['bio'] %> </p>

    <p> <b> Want to work with <%= roster['name'] %>? </b> <%= link_to image_tag('yes.jpg', class: 'yes'), rosters_path, method: :patch %>

    <br>

    <%= roster['vote'] %> People have said Yes! </p>

    <br>

  </div>

<% end %>

I would like that every time someone clicks on yes.jpg, the roster['vote'] increases by 1.

Currently my routes are set up as follows:

get 'rosters', to: 'rosters#index'

patch 'rosters', to: 'rosters#count_vote'

I'm trying to accomplish this without jquery or ajax, that's why I have the if roster.update portion to redirect to rosters_path, so it basically refreshes the page upon click. Right now it isn't updating the vote total however, I'm not sure what I'm missing. I would like to do it all on a single page so if its not possible without JQuery, any guidance in right direction is appreciated.

count_vote will silently fail if it cannot find your Roster or if the update cannot be saved. Change it so it raises an exception of anything fails.

  def count_vote

    roster = Roster.find(params[:id])

    roster.vote += 1

    roser.save!

    redirect_to rosters_path

  end

find will raise RecordNotFound if the Roster cannot be found. save! will raise an error if the changes cannot be saved.

These are the only params currently for some reason ActionController::Parameters {"_method"=>"patch", "authenticity_token"=>"qbORnCLNnI9P1zUZ02VEP3qJMwYOGa5sGw6KblPFj99mvjwZQj9VnDQ2e+6ZStJi3PJZ3MidSMsdoWlwOgBN9w==", "controller"=>"rosters", "action"=>"count_vote"} permitted: false> how would I add an id param? – Sohel 5 hours ago

I'm not very familiar with how views work, but I think as in this example, I believe you need to pass the roster into rosters_path.

<%= link_to image_tag('yes.jpg', class: 'yes'), rosters_path(roster), method: :patch %>

Similarly, if you want count_vote to redirect back to the roster you just changed...

redirect_to rosters_path(roster)
