I want to add PayPal payment system to my RoR app. For this I did install paypal-sdk-rest gem.
I have a model Feed and inside of index.html.rb, where the route is:
get '/:locale/feed', to: 'feed#index', as: 'feed'
I want to paste the next code:
<%= link_to 'checkout', feed.paypal_url(products_url) %>
And inside of the model feed.rb:
def paypal_url(return_url)
values = {
:business => 'my_paypal_mail#gmail.com',
:cmd => '_cart',
:upload => 1,
:return => return_url,
}
values.merge!({
"amount_1" => unit_price,
"item_name_1" => name,
"item_number_1" => id,
"quantity_1" => '1'
})
"https://www.sandbox.paypal.com/cgi-bin/webscr?" + values.to_query
end
But it prints me, that:
undefined local variable or method `feed' for #<#<Class:0x007f5644b79520>:0x007f5644b89858>
on
<%= link_to 'checkout', feed.paypal_url(feeds_url) %>
What is the problem and how can I fix this error?
UPDATE
I just want to paste button just for payment, to my website with the amount 1$. How can I make it?
Where is feed object defined? If in controller then it should be instance variable like #feed, To access variables defined in controller from views we have to defined them as instance variables like #feed.

I have experimented with the following example:
class Student
...
end
student_list = [std1, std2, ... stdn]
When I use
<%= link_to_remote("example", :url => {:controller => 'class/assignment',
:action => 'homework',
:student => student_list})%>
It did not work the way I expected. params[:student] is equal to "student" (string literal).
Is there anything I did wrong, or an alternate way of doing it?
I have the following method in my controller:
def update_fees_collection_dates_voucher
#batch = Batch.find(params[:batch_id])
#dates = #batch.fee_collection_dates
render :update do |page|
page.replace_html "fees_collection_dates", :partial =>"fees_collection_dates_voucher"
end
end
the method calls the following partial in _fees_collection_dates_voucher.html.erb file:
<%= select :fees_submission, :dates_id, #dates.map { |e| [e.full_name, e.id]},{:prompt => "#{t('select_fee_collection_date')}"},{:onChange => "#{remote_function( :url => {:action => "load_fees_voucher"},:with => "'date='+value+'&batch_id='+#batch.id") }"} %>
The partial makes a remote call to the load_fees_voucher method when a selection list value is selected or changed. However, I'm unable to pass the information in the #batch instance variable (from my original method) to the remote method via the partial. If I change the #batch.id to a hard-coded value in the last line (under :with) the code runs fine but not in the current format. Is there a different procedure to access instance variables in partials ? Thanks!
You can use the same instance variable in the partials.
Try this,
<%= select :fees_submission, :dates_id, #dates.map { |e| [e.full_name, e.id]},{:prompt => "#{t('select_fee_collection_date')}"},{:onChange => "#{remote_function( :url => {:action => "load_fees_voucher"},:with => "'date='+value+'&batch_id='+#{#batch.id}") }"} %>
I'm currently working on a tour interface that guides new users around my site. I have a Tour model that has many TourStops, each of which contains information about a section of the site.
Basically, I'd like to write a function for the Tour model that -- when passed the number of a TourStop -- generates the correct class and data attribute for the HTML element it's attatched to. For example, I'd like
<%= link_to image_tag("new_button.png", tour.stop_data(1), :title => 'Add new asset'), new_asset_path %>
to call a function and return something like
def stop_data(order)
" :class => '#{tour_stops.find_by_order(order).name}',
:data => '{:order => order}'"
end
creating a link_to tag like:
<%= link_to image_tag("new_button.png", :class => 'tour_stop_1',
:data => {:order => 1}, :title => 'Add new asset'), new_asset_path %>
The above code doesn't work. Is something like this even possible? If not, what's a better approach I might take?
The image_tag accepts two parameters. A source, and a options Hash.
What you are trying to do is squeezing your return value from stop_data into this options Hash.
In order to get this to work, you first, need to return a Hash from stop_data, and second, make sure you pass only two arguments to image_tag - the source, and the options.
First:
def stop_data(order)
{
:class => tour_stops.find_by_order(order).name,
:data => { :order => order } # you may need order.to_json
}
end
Second:
link_to image_tag("new_button.png", tour.stop_data(1), :title => "Add new asset"), new_asset_path
This looks like it will work, but it won't, since your'e passing three parameters to image_tag.
When you do the following:
image_tag("new_button.png", :class => "tour_stop_1", :data => { :order => 1 }, :title => "Add new asset")
It looks like you're passing even 4 parameters to image_tag, but in fact they are only two. In Ruby, when the last parameter of a method is a Hash, you don't need to wrap the Hash key/value pairs in curly braces ({}), so the example above is essentially the same as
image_tag("new_button.png", { :class => "tour_stop_1", :data => { :order => 1 }, :title => "Add new asset" })
Now, to get your helper to work with image_tag, you need to merge the options, so they become only one Hash.
link_to image_tag("new_button.png", tour.stop_data(1).merge(:title => "Add new asset")), new_asset_path
Again, we're omitting the curly braces when calling merge, because it's only (and therefore last) parameter is a Hash. The outcome is the same as:
tour.stop_data(1).merge({ :title => "Add new asset" })
I am trying to implement Paypal into an application of mine. I have gone through the excellent railscasts demo at http://railscasts.com/episodes/141-paypal-basics
However I dont really have a cart in my app, its more of a one off purchase. But I want to get Paypal intergrated and not just have a "button".
I took the Cart model from the demo and built my own:
class Paypal < ActiveRecord::Base
def paypal_url
values = {
:business => 'seller_1229899173_biz#railscasts.com',
:cmd => '_cart',
:upload => 1,
:return => return_url,
:invoice => id
}
"https://www.sandbox.paypal.com/cgi-bin/webscr?" + values.to_query
end
end
Then for a link in my view I have:
<%= link_to "Checkout", #paypal.paypal_url(products_url) %>
I know this is not right, as I dont have any products as such. But I would like to pass varilables to payal and recieve variabled back. At the moment I get the error:
undefined method `paypal_url' for nil:NilClass
Which happens on load.
In my routes I have included:
resources :paypal
But no joy!
I have a group#view page, that is accessed by a Person. In this page, the Person can see the members of the group via methods I developed. The problem is that I need to create the model Honors using the Id from the group, the id from the person accessing the page, and the id from a member of this group.
In my Honors controller I have:
def create
#person = Person.find(current_person)
#honor = Honor.create(:group => Group.find(params[:group_id]),
:person => Person.find(current_person), :honored => Person.find(current_person))
if #honor.save
...
end
The problem is in this :honored => Person.find(current_person), that is not getting the right ID and I don`t know how to get it.
In my view:
<% #asked_groupmembership.each do |agm| %>
<% form_for(:honor, :url => honors_path(:group_id => #group.id, :person => current_person.id,:honor => agm.member.id)) do |f| %>
Any help?
Thanks.
If you need 3 components to properly create an honor record, you need to pass them from the form. You seem to be doing that part correctly.
:group_id => #group.id
:person => current_person.id
:honor => agm.member.id
To create the record, access the passed variables.
Honor.create(:group => Group.find(params[:group_id]),
:person => Person.find(params[:person]),
:honored => Person.find(params[:honor]))
Understanding the above isn't the most efficient, but used for demonstrative purposes. You'd likely want to avoid redundant database hits, e.g. :person => current_person rather than another query
