Ruby on rails RubyonRails：表单路由到不同的URL

我有一个保存数据的表单，但它被路由到错误的URL

如果我的表格在

localhost:3000/users/1/styles/1

当我提交表格时，我会被重定向到：

localhost:3000/styles/1

然后我得到一个错误：

找不到没有ID的用户

views/comments/_form.html.erb

<%= form_for [@commentable, @comment] do |f| %>
  <%= f.text_area :content, rows: 3 %>
  <%= f.submit %>
<% end %>

def show
  @user = User.find(params[:user_id])
  @style = @user.styles.find(params[:id])
  @commentable = @style
  @comments = @commentable.comments
  @comment = Comment.new
end

before_filter :get_commentable

def new
  @comment = @commentable.comments.new
end

def create
  @comment = @commentable.comments.new(params[:comment])
  @comment.user = current_user
  if @comment.save
    redirect_to @commentable, notice: "Comment created."
  else
    render :new
  end
end

private
def get_commentable
  @commentable = params[:commentable].classify.constantize.find(commentable_id)
end

def commentable_id
  params[(params[:commentable].singularize + "_id").to_sym]
end

resources :styles do
  resources :comments, :defaults => { :commentable => 'style' }
end

评论\u controller.rb

<%= form_for [@commentable, @comment] do |f| %>
  <%= f.text_area :content, rows: 3 %>
  <%= f.submit %>
<% end %>

def show
  @user = User.find(params[:user_id])
  @style = @user.styles.find(params[:id])
  @commentable = @style
  @comments = @commentable.comments
  @comment = Comment.new
end

before_filter :get_commentable

def new
  @comment = @commentable.comments.new
end

def create
  @comment = @commentable.comments.new(params[:comment])
  @comment.user = current_user
  if @comment.save
    redirect_to @commentable, notice: "Comment created."
  else
    render :new
  end
end

private
def get_commentable
  @commentable = params[:commentable].classify.constantize.find(commentable_id)
end

def commentable_id
  params[(params[:commentable].singularize + "_id").to_sym]
end

resources :styles do
  resources :comments, :defaults => { :commentable => 'style' }
end

routes.rb

<%= form_for [@commentable, @comment] do |f| %>
  <%= f.text_area :content, rows: 3 %>
  <%= f.submit %>
<% end %>

def show
  @user = User.find(params[:user_id])
  @style = @user.styles.find(params[:id])
  @commentable = @style
  @comments = @commentable.comments
  @comment = Comment.new
end

before_filter :get_commentable

def new
  @comment = @commentable.comments.new
end

def create
  @comment = @commentable.comments.new(params[:comment])
  @comment.user = current_user
  if @comment.save
    redirect_to @commentable, notice: "Comment created."
  else
    render :new
  end
end

private
def get_commentable
  @commentable = params[:commentable].classify.constantize.find(commentable_id)
end

def commentable_id
  params[(params[:commentable].singularize + "_id").to_sym]
end

resources :styles do
  resources :comments, :defaults => { :commentable => 'style' }
end

如果需要其他信息，请告诉我。为什么要将我重新路由到其他url？我的评论会保存到我的数据库中

谢谢

如果您想在创建评论后返回到

localhost:3000/users/1/styles/1

，您应该更改

  if @comment.save
    redirect_to @commentable, notice: "Comment created."
  else

到

编辑：应该使用拥有样式的用户而不是当前用户

当您在浏览器的视图源中查看表单HTML时，是否看到正确的URL？（我想不是，但只是问一下，因为你说它“重定向”到了错误的URL）@RajeshKolappakam是的，

action=“/styles/1/comments”

rails获得正确答案的最佳实践是什么？我试图获得的是当前id，而不是当前用户的登录id。它只会将它重定向到正在评论的人。我尝试了

params[：user\u id]

但它不正确，这对我有帮助，但我如何保留我正在评论的当前URL的id？只需使用user.find（params[：user\u id]）
