Re: Need help...NameError in InteractController#add_to_cart

Though I have only been playing with Rails for about a month, I think I can
answer this one.

You need to define add_a_cart in the store_controller.rb.

Good luck.

Re: Need help...NameError in InteractController#add_to_cart

This is what I have got.Will appreciate it if you can go through this and
amend.Note the method highlighted.

class InteractController < ApplicationController  def index    @products =
Product.find_products_for_sale  end    def add_to_cart  product =
Product.find(params[:id])  @cart =
find_cart   -wb5DWc3F33w@public.gmane.org_product(product)  rescue
ActiveRecord::RecordNotFound     logger.error("Attempt to access invalid
product #{params[:id]}")    flash[:notice] = "Invalid product"  
 redirect_to :action => ''index''end
def empty_cart  session[:cart] = nil   flash[:notice] = " Now,your cart is
currently empty"   redirect_to :action =>
''index''end  private
def redirect_to_index(msg)    flash[:notice] = msg   redirect_to :action =>
''index'' end end

Where? I cannot see the method find_cart in the code you have posted.

By the way top posting is disapproved of here, it is easier to follow
a thread if you insert your reply in the appropriate place in the
previous post.

Did you see the comment on top posting in my previous post?

It is always worth looking carefully at error messages as sometimes
they contain useful information.  Yours said "undefined local variable
or method `find_cart''" which could have given you a clue to the
problem.

I am afraid I cannot help out with it as I have no idea what your
application is supposed to do.  Presumably you can find something
about it in the tutorial you are following.

For beginners I always recommend working through the Rails Guides,
particularly the one on Getting Started.  See
http://guides.rubyonrails.org/

Re: Need help...NameError in InteractController#add_to_cart

Hi,
Check if find_cart may be some method which you must be missing, either
check your helper file too.

Hi,
Check if find_cart may be some method which you must be missing, either check
your helper file too.

Did you see the comment on top posting in my previous post?



It is always worth looking carefully at error messages as sometimes

they contain useful information.  Yours said "undefined local variable

or method `find_cart''" which could have given you a clue to the

problem.



I am afraid I cannot help out with it as I have no idea what your

application is supposed to do.  Presumably you can find something

about it in the tutorial you are following.



For beginners I always recommend working through the Rails Guides,

particularly the one on Getting Started.  See

http://guides.rubyonrails.org/

In the sample application used in ''Agile Web Development with
Rails''
they define a Cart class (which is not derived from
ActiveRecord::Base).&nbsp; In their StoreController class they define a
find_cart method as:<br>
[code]<br>
def find_cart <br>
&nbsp; @cart = (session[:cart] ||= Cart.new)<br>
end<br>
[/code]<br>
Whether this has any applicability to your case is impossible to know

        Hello,
        thank you for your time.I am actually developing an e
commerce website for selling books online.the find_cart method is mean
to find the cart displayed at the front end-for the users buying
stuffs.Your help wil be appreciated,am just 2 weeks old in RoR

        

        Regards and Respects,

        
        
      
    
  

In the sample application used in ''Agile Web Development with
Rails''
they define a Cart class (which is not derived from
ActiveRecord::Base).  In their StoreController class they define a
find_cart method as:

[code]

def find_cart 

  @cart = (session[:cart] ||= Cart.new)

end

[/code]

Whether this has any applicability to your case is impossible to know
without knowing a lot more about your application.

There is no point repeatedly posting the same code.  As has been
pointed out several times the problem is that you are missing the
find_cart method.  In Agile Development With Rails this is in the
StoreController, as has also been pointed out to you previously.  I
suggest you go back to the book and have another look.  I believe you
can even download the application source if you wish.

The error is in your model/cart.rb around line 19 as the error message
indicates.  Read the error messages closely and you will find a lot of
information.  The error indicates that you have a syntax error in
model/cart.rb.  Maybe a block opened without an end or quotes not
matching or parentheses not matching etc.
