Question

I’m trying to use jQuery Tokeninput as shown in Railscast #258 (revised). When I enter something in the tokeninput field, the field does not dropdown with results and I get the following javascript error: Uncaught TypeError: Cannot call method 'replace' of undefined.

My json data works fine when I do a manual query on it, and the server request looks fine. I am trying to search the content column in my issues table, so I set propertyToSearch to “content”.

Here is my code:

coffeescript:

jQuery ->
$('#fact_issue_tokens').tokenInput "/issues.json"
    theme: 'facebook'
    zindex: 11001
    propertyToSearch: 'content'
    tokenValue: 'content'
    hintText: 'Enter an issue'
    preventDuplicates: true

Issue Model:

def self.tokens(query)
  issues = where("content like ?", "%#{query}%")
  if issues.empty?
    [{id: "<<<#{query}>>>", content: "New: \"#{query}\""}]
  else
    issues
  end
end

def self.ids_from_tokens(tokens)
  tokens.gsub!(/<<<(.+?)>>>/) { create!(content: $1).id }
  tokens.split(',')
end

Issues Controller:

def index
  @issues = Issue.order(:content)

  respond_to do |format|
    format.html
    format.json { render json: @issues.tokens(params[:q]) }
  end
end

Form:

<%= form_for(Fact.new, :url => kase_facts_path(current_kase), :html => {:class => "form-   
inline"}) do |f| %>

  <%= f.text_field :page, placeholder: 'Page' %>
  <%= f.text_field :description, placeholder: 'Description' %>

  <%= f.label :issue_tokens, 'Issue tags' %>
  <%= f.text_field :issue_tokens %>

  <%= f.hidden_field :source_id, :value => @source.id %>

  <%= f.submit 'Add Fact' %>
<% end %>

@Scott you try this

jQuery ->
  $('#fact_issue_tokens').tokenInput '/issues.json'
    theme: 'facebook'
    tokenLimit: 5
    minChars: 4
    preventDuplicates: true
    searchingText: "Enter an issue..."
    prePopulate: $('#fact_issue_tokens').data('load')

and think on your index because you are using (:content) not name might be your problem. I am bot sure why but i used title and i had a problem, i thought it was mysql or something.
When you visit

http://localhost:3000/issues.json

Do you get the JSON data?

Edit.

Can you please try this for your form?

<div class="field">
  <%= f.label :issue_tokens, "Issues" %><br />
  <%= f.text_field :issue_tokens, data: {load: @fact.issues} %>
</div>
