I tried to generate a form it says “undefined method `posts_path’ for
#<#Class:0xb6784798:0xb67817f0>”
The following code at line number 2 gives the error.
<%= link_to ‘New Post’%>
<%= form_for(@post) do |f| %>

Please run rake routes and post that here, or just read through it and
see whether posts_path is listed. What does your routes.rb look like?

Check your routes file for the routes for post.
If you scaffolded the model, then there should be
resources :post
in your routes.rb file.
If the above is not there, just add the line and you will get the routes
for
CRUD automatically.

Have a look at the Rails Guide on Routing to see how routing works.
Read it through carefully and make sure you understand it. Then you
will easily answer your question yourself.

Please run rake routes and post that here
rake routes shows
posts_index GET /posts/index(.:format)
{:action=>“index”, :controller=>“posts”}

router.rb file looks like:
Check::Application.routes.draw do
get “posts/index”
and :action
=> :purchase
automatically):
RESTful applications.
accessible via GET requests.
end

Look at the error and try and work out what it means. There should
also be an indication of which line generated the error.
Error is generated at link 8 in following code.
<%= link_to ‘New Post’, new_post_path%>
<%= form_for(@post) do |f| %>
Posts_controller.rb file looks like:
class PostsController < ApplicationController
def try
@post = Post.new
end
def create
@post = Post.new(params[:post])
respond_to do |format|
end
end

Look at the error and try and work out what it means. There should
also be an indication of which line generated the error. It says
undefined method ‘name’, so that suggests you are calling the method
name for something. It tells you that the object you are calling it
on is a Post object. Have a look at your code, can you see where the
error is being generated? Assuming that you can see that you are
calling name on a Post object, does Post have a method called name?
Assuming that Post is an ActiveRecord model then is the posts table
supposed to have a name column? If so does it have such a column?

Here you are asking to display (and allow entry) of @post.name,
whereas the error suggests that Post does not have a method ‘name’.

‘name’ is field that i want to generate in form.Let me tell you i
have total 3 files
1)posts_controller.rb(code is above)
2)try.html.erb(/view/posts)(code is above)
3)post.rb(Model)(Empty)

You are confusing things a lot.
Answer this question first:
Did you scaffold the model or you are adding the files one by one
writing
the code by hand.
As of the current problem that you are facing, do this:

I didnt scaffold.I am adding files one by one.
- If you did scaffold, I don’t see a problem coming anywhere.
- If you didn’t scaffold, then go for Colin’s suggestion and read the
guides, you will understand how Rails works.
AND read the guides rightnow, before you get troubled by another problem.As of the current problem that you are facing, do this:
- Look up the database table for posts, and see if you have a column named
‘name’ in there. If not, what went wrong.
In ‘posts’ table there is no column for name,title and content.- I am quite sure, 1st would fail. Now, look up your post.rb model file and
see if there is
attr_accessible : name
in your model file.
It is not there,but after adding it there ,error didnt resolve.

I suggested before reading the Rails Guide on Routing. I also suggest
that you read the Getting Started guide and then the others. Also
work through a good tutorial (make sure it is for the version of Rails
that you are using). railstutorial.org is a good free to use online
tutorial. The reason is that you are missing some fundamental
understanding of how Rails works. When you do form_for(@post) and
then f.text_field :name rails expects @post to have a method ‘name’ to
get the initial value for display. Often this will come automatically
from the fact that the posts table will contain a column ‘name’.
Since you have no such column it complains that Post has no method
‘name’.

As of the current problem that you are facing, do this:manually to table ‘posts’ OR changes should be made in
Model.
You can add them using migrations. railstutorial.org will show you
how to do that.

I created migration and added following code inside and then did
“rake db:migrate” but still the same error persists.I think now it might
work,but it did not.
Have you worked right through railstutorial.org already?
