Hi, everybody:
I made a view - works as creating a new comment for a specific
article, a example URL is "http://localhost:3000/comments/new/2":
here, comments is the controller, new is the action, 2 is the id of
the specific article, which needs to be passed to next action
"create", so that this comment will be attached and displayed under
2nd article. However, I didnt figure out how I can pass the id to next
action named "create" in this controller, seems like only the
"comments" is the only parameter when I click the "create"
button...
what can I do?
the new view as follow:
===============================
<h1>New comment</h1>
<%= error_messages_for :comment %>
<% form_for(@comment) do |f| %>
<p>
<b>Desc</b><br />
<%= f.text_area :desc %>
</p>
<p>
<%= f.submit "Create" %>
</p>
<% end %>
=================================
Thanks dudes!
Myst

To Ryan: Suddenly, I realise that your previous answer was not really what I asked.. Here, the id "2" in "http://localhost:3000/comments/new/2" is already what I would like to send to next action, but if i do " s params[:id]" in next action, it says id is not the parameter delivered , only the params[:comment] is. how could I let the next action get this "2" value?? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Simplest answer is to add something like this to your form: <%= f.hidden_field :article_id, params[:id] %> which would give your create action params[:comment][:article_id] More complicated answer is to rework your routes and controller code to handle nested resources for comments. i.e. /articles/2/comments/new instead of /comments/new/2 -Justin Blake On Jan 10, 7:05 pm, myst_tt <tdxia...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi, everybody: > I made a view - works as creating a new comment for a specific > article, a example URL is "http://localhost:3000/comments/new/2": > here, comments is the controller, new is the action, 2 is the id of > the specific article, which needs to be passed to next action > "create", so that this comment will be attached and displayed under > 2nd article.

Thank you Justin, actually now I am thinking of why this :id param
is not passed to "create" action since the URL really matches the
routing rule "controller/action/id" in my routing map, it does have
the id. Is it because the new view contains a form?
Ok, let''s say if I try the nested RESTful route and the URL
changes to "tasks/1/comment/2" which matches the REST routing map
"task/task_id/comment/comment_id", then in the new view to create
action, all these "task_id" and "comment_id" will be
delivered to
create action?
I dont know if I express myself clearly, but really dont figure out
the reason.

btw, if I try your simple answer, add the "hidden_field" in comment form. However, it errors as follow: ==============================undefined method `merge'' for "2":String Extracted source (around line #21): 18: <%= f.text_field :img_url %> 19: </p> 20: 21: <p><%= f.hidden_field :article_id, params[:id] %></p> 22: 23: <p> 24: <%= f.submit "Create" %> ============================= Plus, I need to store the comment into database in create action, which actually does not has the column "article_id", am I able to kick it out before store into database? Got the feeling that this messes my code a bit...
