问题:我的目标是在用户页面下列出项目,并在此用户页面上列出的每个项目下呈现评论框。但是当我尝试呈现评论框表单时,我收到了路由错误。我知道这是因为它无法提取项目的 ID。我的猜测与控制器有关,但尚未弄清楚。有人知道我该如何解决这个问题吗?
Routing Error
No route matches {:controller=>"comments", :format=>nil, :project_id=>#<Project id: nil...>}
对于我的应用程序,我为用户、项目和评论创建了模型和控制器。评论属于项目,项目属于用户
用户.rb
has_many :projects
项目.rb
has_many :comments
belongs_to :user
评论.rb
belongs_to :project
路线.rb
resources :users do
resources :projects do
resources :comments
end
end
resources :projects do
resources :comments
end
resources: comments
查看/用户/projects.html.erb
<%= render @projects %>
查看/项目/_project.html.erb
<%= project.content %>
<%= render 'comments/form' %>
查看/评论/_form.html.erb
<%= form_for([@project, @project.comments.build]) do |f| %>
<div class="field">
<%= f.text_area :content, :class => "span12", :rows => "3" %>
</div>
<%= f.hidden_field :user_id, :value => current_user.id %>
<div class="actions">
<%= f.submit "Add Comment", :class => "btn btn-header" %>
</div>
<% end %>
评论控制器.rb
def create
@project = Project.find(params[:project_id])
@comment = @project.comments.create!(params[:comment])
if @comment.save
redirect_to projects_user_path(@project.user)
end
end
来自上述重定向的错误
NoMethodError in CommentsController#create
undefined method `user'
