Question

无法访问由 current_user 创建的项目。

project_controller.rb

def index
  @projects = current_user.projects.all
end

  def create
    @project = current_user.projects.build(project_params)

    respond_to do |format|
      if @project.save
        #ProjectMailer.activity_status(@project).deliver

        format.html { redirect_to projects_url, notice: 'Project was successfully created.' }
        format.json { render :show, status: :created, location: @project }
      else
        format.html { render :new }
        format.json { render json: @project.errors, status: :unprocessable_entity }
      end
    end
  end

index.html.erb

      <% @projects.each do |project| %>
        <tr>
          <td><%= project.project_name %></td>
<tr>
<% end %>

user has_many project
和 project has_many user.

project.rb

has_many :users, through: :project_users

user.rb

  has_many :project_users

项目_user.rb

  belongs_to :user
  belongs_to :project

检查一下你的user.rb型号，我猜应该是

has_many :project_users
has_many :projects,  through: :project_users

在您的项目模型中：

has_many :project_users
has_many :users, through: :project_users

在此处参考文档https://guides.rubyonrails.org/association_basics.html#the-has-many-through-association
