RoR- Show page not showing user's name - ruby-on-rails

Question

I'm trying to bring a list of Users that a "request" has been accepted for a user to select from. I set up the collection and what is showing up on the view page is either the user id when I put :user_id or its shows <User:0x007fbdrf252a60> when i put in user. I tried putting in :name but it returns a "undefined method name" error.
Currently my form looks like:
<%= form_for :event_logs, url: event_logs_path do |f| %>
<%= f.select :user_id, options_from_collection_for_select(#user_event_log, :id, :name ) %>
<%= f.hidden_field :event_id, :value => #event.id %>
<%= f.submit 'Send', class: 'btn btn-success' %>
<% end %>
And in the controller for the show its:
#user_event_log = RequestLog.usr_req_by current_user
The user_req_by in the model is: scope :usr_req_by, ->(user) { where(user_id: user.id) }
If more information is needed I'm more than happy to add it. Thank you
User Model:
class User < ApplicationRecord
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :validatable
validates_presence_of :name
has_many :request_logs, dependent: :destroy
acts_as_messageable
def first_name
self.name.split.first
end
def last_name
self.name.split.last
end
end
Request Log Model:
class RequestLog < ApplicationRecord
enum status: { accepted: 0, rejected: 1 }
belongs_to :user, optional: true
belongs_to :request, optional: true
validates :user_id, presence: true
validates :request_id, presence: true
scope :usr_req_by, ->(user) { where(user_id: user.id) }
scope :req_itp, ->(requests) { where(request_id: requests) }
end

The collection iterated over, is a collection of RequestLog. So when you use :name in options_from_collection_for_select, it tries to call .name on a RequestLog.
I suppose you want the users name there? If so, you can add a helper method to RequestLog
def user_name
return user.name
end
and use :user_name in the view.
Another option, is to pass an object, that responds to .call as a param, as so:
<%= form_for :event_logs, url: event_logs_path do |f| %>
<%= f.select :user_id, options_from_collection_for_select(#user_event_log, :id, ->(log){ log.user.name }) %>
<%= f.hidden_field :event_id, :value => #event.id %>
<%= f.submit 'Send', class: 'btn btn-success' %>
<% end %>
I haven't tried this out, but I did look at the source for options_from_collection_for_select, that uses value_for_collection under the hood; Defined as
def value_for_collection(item, value)
value.respond_to?(:call) ? value.call(item) : public_or_deprecated_send(item, value)
end
