Form builder not working

[ausangshukla]

The code to generate the form is not working
= f.collection_check_boxes :languages, Profile.languages.pairs

wrong number of arguments (given 2, expected 4..6)

Would there be a way to resolve this ? Thanks

I solved this manually as follows

<% User.permissions.pairs.each do |key, val| %>
  <div class="form-group">
    <%= form.label :permissions, key %>
    <%= form.check_box :permissions, {name: "user[permissions][]",  
        val: val, id: "permissions_#{val}", class: "form-control form-checkbox"}, val, nil   %>
  </div>
  <% end %>

I am using rails 6.1 and was also running into the same problem. After reading the docs on the collection_check_boxes helper about 6 times, I noticed that they said:

The :value_method and :text_method parameters are methods to be called on each member of collection. The return values are used as the value attribute and contents of each check box tag, respectively. They can also be any object that responds to call, such as a proc, that will be called for each member of the collection to retrieve the value/text.

So I tried using a Proc in place of the value_method and name_method and was able to use that to extract the entries from the array.

<div class="field mb-4">
    <%= f.label :industries %><br />
    <%= f.collection_check_boxes :industries, Athlete.industries.pairs, Proc.new {|industry| industry[1]}, Proc.new {|industry| industry[0]}, html_options: { class: 'form-control w-100 w-lg-50' } %>
</div>

Another option I found is you can represent each pair as an array and use the :last and :first methods

<div class="field mb-4">
    <%= f.label :industries %><br />
    <%= f.collection_check_boxes :industries, [[:industry_1, "Industry 1"], [:industry_2, "Industry 2"]], :first, :last, html_options: { class: 'form-control w-100 w-lg-50' } %>
</div>
