Question

I have this in my controller:

class TeamsController < ApplicationController
  respond_to :json 
  def index
    @teams = Teams.all
    respond_with @teams 
  end
  def show
    @team = Teams.find params[:id]
    respond_with @team
  end

This is how my views look like:

<%= render partial: "team", object: @team %> #file-show.json.erb
[<%= render partial: "team", collection: @teams, spacer_template: "comma" %>] #file-index.json.erb
<%= @team.to_json.html_safe %> #file- _team.json.erb

but the response for teams.json is always [null, null, null] while the response for teams/1.json is correct {“id”…}
Any idea what am I doing wrong?

Answer 1

In your _team.json.erb partial you are using the variable @team which is only set up in your show action. If you use team instead it should work because the partial rendering process sets that to be either @team or each of @teams in the case of show and index respectively.

So, your partial should be :

<%= team.to_json.html_safe %>
