Rails 4 - Link_to action create with params

link-to, ruby-on-rails

Solution

index:-

<%= link_to "Like this property", likes_path(:user_id => current_user.id, :property_id => property.id), :method => :post %>

In controller:-

def create
@like = Like.new(:user_id => params[:user_id], :property_id => params[:property_id])

respond_to do |format|
  if @like.save
    format.html { redirect_to properties_path, notice: 'Like was successfully created.' }
    format.json { render action: 'show', status: :created, location: @like }
  else
    format.html { render action: 'new' }
    format.json { render json: @like.errors, status: :unprocessable_entity }
  end
end
end

Problem

I would like to add a link into my rails app which will allow my users to "like" a resource (property) directly. To click on that link will add the like into the db without asking anything to the user. The `like` table: `user_id`, `property_id` As you can see, `user_id` and `property_id` have to be in the `link_to` as params. routes.rb: ``` resources :likes resources :properties ``` index: ``` <%= link_to "Like this property", new_like_path(current_user, property.id) %> #does not work but you get the idea ``` controller: ``` def new @like = Like.new end def create @like = Like.new(like_params) respond_to do |format| if @like.save format.html { redirect_to @like, notice: 'Like was successfully created.' } format.json { render action: 'show', status: :created, location: @like } else format.html { render action: 'new' } format.json { render json: @like.errors, status: :unprocessable_entity } end end end ``` So I am in `properties#index` and I would like to call a `create` method to add a like on that property.
