In volume_prices.html.erb you can't add the first volume discount price. By changing line 23 to <%= link_to_add_fields t(:add_volume_price), "tbody#volume_prices" %> I was able to get the page to load but there were no fields available to create a volume discount.

If I manually added a quantity discount price for that item into the database then the values from the database would show up on the product volume pricing page and clicking the add volume pricing link would insert new fields into the page that could be filled in and updated properly.

Steps to repeat:

• Install spree 2.1

• load spree sample data

• Install this gem (2.1)

• Create examples in the admin interface (these examples from the README.md)

  Variant                Name               Range        Amount         Position
   -------------------------------------------------------------------------------
  Rails T-Shirt          1-5                (1..5)       19.99          1
  Rails T-Shirt          6-9                (6...10)     18.99          2
  Rails T-Shirt          10 or more         (10+)        17.99          3
  

• Create your own product page (copy it from the spree gem): app/views/spree/products/show.html.erb

• add the partial to you overridden product page

  <%= render :partial => 'spree/products/volume_pricing', :locals => { :product => @product } %>
  

• start your webserver

• Navigate to the product page

The problem:
Strictly a display issue only: clicking the different images of the product changes the product image, but the partial only ever displays the pricing from the master.

As far as I can tell the correct price is used when you click the variant and add to your cart, but it'd be confusing for a user if you had different volume prices per variant but they are only displayed the master one.

I get this argument error when adding an item in the admin of spree 1.3.2 and using the plugin spree_volume_pricing branch 1-3-stable

It seems that the method copy price in spree/model/line_item.rb has changed end now returns a currency string

Since Rails 5.1 we should explicitly define that belongs_to relation is optional. Some models fails to save because it doesn't have variant created in specs. We should add optional to belongs_to relations.

The gemspec's spree_core dependency is listed as >= 0.70.0, which means that it installs Spree 1.0.3 as of 2 April 2012 when running bundle install. The Rakefile also does not use Bundler to setup the load paths.

Documentation is missing what needs to be passed to api2 to be included in the product response. Maybe, there is no api v2 support. In general I did not see if this is already compatible with spree 4.x (although it could be included w/o errors into my project).

So my questions / recommendations / issues:

• How to use with apiv2?
• What spree Versions are supported?

Dependabot can't resolve your Ruby dependency files.

As a result, Dependabot couldn't update your dependencies.

The error Dependabot encountered was:

Bundler::VersionConflict with message: Bundler found conflicting requirements for the Ruby version:
  In Gemfile:
    Ruby (~> 2.2.10.0)

    spree_dev_tools was resolved to 0.1.8, which depends on
      Ruby (>= 2.3.0)

If you think the above is an error on Dependabot's side please don't hesitate to get in touch - we'll do whatever we can to fix it.

View the update logs.

I created a variant volume price and added the 2x products of that variant to the cart. The price is not affected at all, until I change the item amount to 3x, update the cart and then change it back to 2x.

The price volume has a range of 2..2. I want to make a discount when you just get two items instead of one.

Any clues?

I've got a pretty vanilla spree 2.1 app and I'm getting this error. Tried overriding with deface and with a view override, same error. Overriding 'spree/products/show'

Is there any ability right now (or is it in the road map) to allow an easy way to temporarily disable volume pricing (similar to available_on column for Products)? One solution that comes to mind is an "Enabled" checkbox in the volume pricing views and stored in the VP table.

If I change to a inferior range vprice, the quantity price is not applied correctly in the shopping cart.
affecting 1-3-stable and master, line_item_decorator.rb

if (!new_price.nil? and vprice <= new_price) or vprice <= self.price

The following code is missing in the conditional...
or vprice >= self.price

I'm getting the following error while trying to install this gem.

All prices are being presented as Money. So percents are being displayed incorrectly.

Hi Guys,

I am translating the gem but I noticed that the dropdown list of discount type cannot be translated. Will try to submit a fix for this soon.

I installed this gem following the instructions (2-1-stable). The gem seems to function, but now if I'm in a rails console and I type reload! I get an error about 'admin_volumn_price' being defined twice.

Steps to reproduce:

gem install rails -v 4.0.0
rails _4.0.0_ new my_store2

added the following to my Gemfile

gem 'spree', github: 'spree/spree', branch: '2-1-stable'
gem 'spree_auth_devise', github: 'spree/spree_auth_devise', branch: '2-1-stable'
gem 'spree_volume_pricing', github: 'spree/spree_volume_pricing', branch: '2-1-stable'

run bundle install

run the installer

rails generate spree_volume_pricing:install

Fire up a rails console and type reload!

>rails c
Loading development environment (Rails 4.0.0)
2.0.0p247 :001 > reload!
Reloading...
ArgumentError: Invalid route name, already in use: 'admin_volume_price'
You may have defined two routes with the same name using the `:as` option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with `resources` as explained here:
http://guides.rubyonrails.org/routing.html#restricting-the-routes-created
    from /Users/hirbourj/.rvm/gems/ruby-2.0.0-p247@spreestoretestvolumnpricing/gems/actionpack-4.0.0/lib/action_dispatch/routing/route_set.rb:409:in `add_route'

I checked and I only see "admin_volume_price" in rake routes 1 time.

My routes file:

MyStore2::Application.routes.draw do
  mount Spree::Core::Engine, :at => '/'
end

I cloned this repo and ran the tests and get an error from: Spree::Admin::VariantsController

  bundle install
  bundle exec rake test_app
  bundle exec rspec spec

https://gist.github.com/jhirbour/5714168

Also are there plans to make a branch of this for spree 2.0 ?

When I am set volume range and prices then we make a cart then the prices not changed according to range price

After adding the gem to my gemfile if I run:

rails generate spree_volume_pricing:install

I get the error:

../.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:23:in `require': cannot load such file -- coffee_script (LoadError)

The required "coffee_script" is in /lib/spree_volume_pricing.rb
Gem coffee-rails has its reported status as failing (https://github.com/rails/coffee-rails)

You can remove this requirement because all the javascript files are written in jquery.

there are no field rows when first viewing the edit page and no rows can be created
this stems from the javascript row cloning but I don't know why it broke for spree 2.3.0.beta
it should be able to create a row when no row existed (if a user removes all rows and starts from scratch)

I made a github fork with a new javascript function

Could not find generator 'spree_volume_pricing:install'

First, great work guys, thank you for building this gem.

There are a few features that I would like to propose that be built (I'm not opposed to contributing).

1. Abstract the volume prices a bit by providing attaching them to a Volume Pricing Model, attach the model to the variants rather than the volume prices themselves. This would allow the definition of a few abstract pricing models that could be applied to N products/variants. Updates on each pricing model would propagate to every item using that model.
2. Add the ability to specify a role on volume prices/volume pricing models. This would allow different pricing models for different users, which is necessary in the case of wholesaling etc.
3. I saw another issue #45, which discussed adding a volume pricing to the product which would be applied for every variant belonging to that product. I similarly think this would be a good idea, and perhaps a good build to roll it up into.

What say you?

I'm trying to run the install task in my able but I am getting this error

Hi there,

I just made a product, and volume pricing works perfectly.

However, once i make two variants of the product, the volume pricing no longer applies when i place a product in my shopping cart.

Any ideas? Mayby i have to re-add the volume pricing after defining variants?

I'm using the "2-3-stable" branch.

Nice work on the gem btw:)

Paul

Hello everyone.

reproduce:
bundle exec rails console
"10..20".to_range # => 0..20 but should be 10..20

The first digit of the first number is ignored.

The error is in engine.rb the two from-calls in lines 17 and 20 should just not be there.

Something that has come up before with volume pricing is being able to have it applied to the whole product. An example should make this easier to understand.

You supply uniforms they are often purchased by groups when new recruits join, this can often happen in batches. The group maybe ordering 10 t-shirts but they would be in various sizes. 3 Small, 6 Medium and 1 Large for example. Your volume pricing starts at 10 items per variant but it is unlikely your customers would ever purchase so many of a single size but combining all the sizes in the basket would often qualify.

In the example above you may wish to apply the volume price for each variant based on the total number of products not just the quantity of the individual variant.

So perhaps in the product there is an option to indicate total product quantity volume pricing (total of all variants in cart) or keep the current per variant volume pricing (total per variant).

Hopefully that make sense! My initial thoughts are to use the line items to find the other variants of the same product, sum the line item quantities together and pass that through to the volume price finder for each line item.

Open to the floor for feedback in case this is all complete madness.

I've been struggling with this issue for 2 days now... I give up :). Is this a bug, or my environment?

I'm using pow in my dev environment, but also tested booting webrick to make sure. I have several other spree extensions that work, but spree_volume_pricing has given me nothing but grief:

Using 2-1-stable '815c00317580'

The total price discount type works as expected, but percent discount with an amount of 10 (assuming this is 10% off), I instead get negative numbers when the qty is within my specified range...

Please advise.

Dependencies aren't compatible with latest spree_core revision

bundle install
  ...
  Bundler could not find compatible versions for gem "spree_core":
    In Gemfile:
      spree_volume_pricing (>= 0) ruby depends on
        spree_core (~> 2.0.0) ruby

      spree (>= 0) ruby depends on
        spree_core (2.1.0.beta)

I have some variants that don't require volume pricing and use the price built-in to Spree. When I try to update a particular variant, I get the following error message:

2 errors prohibited this record from being saved:
There were problems with the following fields:
Volume prices amount can't be blank
Volume prices range must be in one of the following formats: (a..b), (a...b), (a+)

Am I required to add a simple (1+) volume price for every variant, even if they don't have actual volume prices?

Volume prices only working when Item Total is less than 0.

In this example the item master price is $20.

Here a discount of $2 should be applied to the order but it isn't.

Now, when the discount is greater than the master price (item total is less than 0) everything works
