我正在创建一个在RubyonRails上运行的应用程序，并使用threadded Gem作为其社区组件：https://github.com/thredded/thredded
目前，在应用程序的威胁部分，它显示
#<User:0x007fd8d5424108>
它应该在哪里显示用户名。
我在User上有一个：name列，用于定义他们的用户名。我也在使用Devise进行注册。
显示用户名时的链接如下所示：<%=link_to thredded_current_user，user_path（thredded_current_user）%>
现在我知道我可以将thredded_current_user更改为thredded_current_user.name，但这需要找到thredded gem中使用的所有位置，将其复制到我的应用程序中，然后更改视图。我想应该有一个更简单的答案，我只是不知道是什么。
除了将thredded_current_user的所有实例更改为thredded_current_user.name之外，还有其他显示用户名的方法吗？
以下是带threadded的初始值设定项的代码：
# frozen_string_literal: true
# Thredded configuration
# ==> User Configuration
# The name of the class your app uses for your users.
# By default the engine will use 'User' but if you have another name
# for your user class - change it here.
Thredded.user_class = 'User'
# User name column, used in @mention syntax and should be unique.
# This is the column used to search for users' names if/when someone is @ mentioned.
Thredded.user_name_column = :name
# The path (or URL) you will use to link to your users' profiles.
# When linking to a user, Thredded will use this lambda to spit out
# the path or url to your user. This lambda is evaluated in the view context.
Thredded.user_path = lambda do |user|
user_path = :"#{Thredded.user_class.name.underscore}_path"
main_app.respond_to?(user_path) ? main_app.send(user_path, user) : "#{user.to_param}"
end
# This method is used by Thredded controllers and views to fetch the currently signed-in user
Thredded.current_user_method = :"current_#{Thredded.user_class.name.underscore}"
# User avatar URL. rb-gravatar gem is used by default:
Thredded.avatar_url = ->(user) { user.profile_picture.url }
# ==> Permissions Configuration
# By default, thredded uses a simple permission model, where all the users can post to all message boards,
# and admins and moderators are determined by a flag on the users table.
# The name of the moderator flag column on the users table.
Thredded.moderator_column = :admin
# The name of the admin flag column on the users table.
Thredded.admin_column = :admin
# This model can be customized further by overriding a handful of methods on the User model.
# For more information, see app/models/thredded/user_extender.rb.
# ==> Email Configuration
# Email "From:" field will use the following
# Thredded.email_from = 'no-reply@example.com'
# Incoming email will be directed to this host
# Thredded.email_incoming_host = 'example.com'
# Emails going out will prefix the "Subject:" with the following string
# Thredded.email_outgoing_prefix = '[My Forum] '
# Reply to field for email notifications
# Thredded.email_reply_to = -> postable { "#{postable.hash_id}@#{Thredded.email_incoming_host}" }
# ==> View Configuration
# Set the layout for rendering the thredded views.
Thredded.layout = 'thredded/application'
# ==> Error Handling
# By defau
lt Thredded just renders a flash alert on errors such as Topic not found, or Login required.
# Below is an example of overriding the default behavior on LoginRequired:
#
# Rails.application.config.to_prepare do
# Thredded::ApplicationController.module_eval do
# rescue_from Thredded::Errors::LoginRequired do |exception|
# @message = exception.message
# render template: 'sessions/new', status: :forbidden
# end
# end
# end
这是我的路线代码：
Rails.application.routes.draw do
get 'page/home'
get 'page/feed'
get 'page/about'
get 'page/contact'
mount Thredded::Engine => '/community'
devise_for :users, :path => '', :path_names => { :sign_in => "login", :sign_out => "logout", :sign_up => "register" }, :controllers => {
:registrations => 'users/registrations', :omniauth_callbacks => "users/omniauth_callbacks" }
resources :users, path: "", only: [:show] do
resources :tracks
end
resources :tracks, only: [:create, :destroy]
resources :feeds, only: [:create, :destroy, :show]
# The priority is based upon order of creation: first created -> highest priority.
# See how all your routes lay out with "rake routes".
# You can have the root of your site routed with "root"
root 'page#home'
# Example of regular route:
# get 'products/:id' => 'catalog#view'
# Example of named route that can be invoked with purchase_url(id: product.id)
# get 'products/:id/purchase' => 'catalog#purchase', as: :purchase
# Example resource route (maps HTTP verbs to controller actions automatically):
# resources :products
# Example resource route with options:
# resources :products do
# member do
# get 'short'
# post 'toggle'
# end
#
# collection do
# get 'sold'
# end
# end
# Example resource route with sub-resources:
# resources :products do
# resources :comments, :sales
# resource :seller
# end
# Example resource route with more complex sub-resources:
# resources :products do
# resources :comments
# resources :sales do
# get 'recent', on: :collection
# end
# end
# Example resource route with concerns:
# concern :toggleable do
# post 'toggle'
# end
# resources :posts, concerns: :toggleable
# resources :photos, concerns: :toggleable
# Example resource route within a namespace:
# namespace :admin do
# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)
# resources :products
# end
end
这实际上与线程化gem无关；视图正在对用户对象调用CCD_ 1。如果将<?= thredded_current_user =>放在视图中，ERB将自动调用thredded_current_user对象上的to_s。在link_to辅助方法中也会发生同样的情况。
您可以覆盖用户模型中的to_s方法，如下所示：
class User < ActiveRecord::Base
def to_s
name
end
...
end
或者，您可以将name方法别名为to_s，如下所示：
alias_method :to_s, :name
