在 Rails 上的 Ruby 中使用带有 form_for 的 collection_select 的未定义方法“id”错误

Question

I'm having an issue with collection_select using form_for in rails. This issue is coming from a method that was working until I namespaced my routes to be only for admin. The admin routes are working as they should as far as I can tell, but it is the only connection I can find to why this method stopped working.

Error:

undefined method `id' for #<Array:0x00007faf084c7048>

Here is the trace if that would help:

Here is the full method:

<%= user_builder.fields_for :team_attributes, [:admin, @team] do |team_builder| %>
            <%= team_builder.hidden_field :profile, :value => "profile" %>
        <% if @company.teams.all == [] %>
            <br><h3>Create a New Team:</h3>
        Team Name: <%= team_builder.text_field :name %>
        Team Description: <%= team_builder.text_area :description %><br><br>
        <% else %>
            <% if @show_form == "new-position" %>
               Change Team: <%= team_builder.collection_select :id, @company.teams, :id, :name, {:include_blank => true} %>
               Or <%= link_to "Create a new Team", "/admin/profile/#{@user.id}/edit/new-team-and-new-position" %><br><br>
            <% elsif @show_form == "new-team" %>
            <% else %>
               Change Team: <%= team_builder.collection_select :id, @company.teams, :id, :name, {:include_blank => true} %>
               Or <%= link_to "Create a new Team", "/admin/profile/#{@user.id}/edit/new-team" %><br><br>
            <% end %>
        <% end %>

The error is being throw here:

Change Team: <%= team_builder.collection_select :id, @company.teams, :id, :name, {:include_blank => true} %>

I threw in a pry and returned the value of @company and the value of @company.teams:

This is attempting to create a drop down of a company's team dependent on if the company has teams and depending on what links the user has clicked to reveal parts of the full form. Basically this error is preventing some substantial functionality and progress towards completing this application. If anyone needs more information to help please let me know. Thanks for the help.

Answer 1

Solved it:/ there was no need for me to namespace @teams in fields_for when the original form_for was already namespaced. Don't go to fast people lol
