* Add support for multiplan subscriptions:
Serialize indexed arrays into hashes with index keys in subscription create, subscription update, and upcoming invoice
Add a SubscriptionItem object that supports creation, deletion, update, listing, and retrieval
* Remove helpers that convert items array to indexed hash
Since #433, saving API resources nested under other API resources has
not been the default. Instead, any instances where this should occur
have been special cased with specific method implementations that would
set the `#save_with_parent` flag when a field is written.
This ended up causing some problems because as seen in #457, because
places that we need to do this aren't well vetted, some were forgotten.
This makes implementation of new fields that need this behavior simpler
by implementing a `.save_nested_resource` metraprogramming method on the
`APIResource` class. This can be called as necessary by any concrete API
resource implementations.
We replace existing implementatinos and also add one to `Subscription`,
which had previously been suffering from a similar problem where its
`#source` had not received a special case.
Add deprecated `#bank_account=` to maintain backwards compatibility.
This would have been broken by #433, so this change keeps the
functionality alive in case someone has not upgraded since.
In #433, we built a framework under which subresources are usually not
persisted, but in certain cases they can be. At the time,
`Customer#source` was the only field that I knew about that had to be
flagged into it.
Issue #456 has raised that we also be doing `Account#external_account`.
This patch adds support for that.
Fixes#456.
This produces an error when we detect an "array of maps" that cannot be
encoded with `application/x-www-form-urlencoded`; that is to say, one
that does not have each hash starting with a consistent key that will
allow a Rack-compliant server to recognize boundaries.
So for example, this is fine:
```
items: [
{ :type => 'sku', :parent => 'sku_94ZYSC0wppRTbk' },
{ :type => 'discount', :amount => -10000, :currency => 'cad', :description => 'potato' }
],
```
But this is _not_ okay:
```
items: [
{ :type => 'sku', :parent => 'sku_94ZYSC0wppRTbk' },
{ :amount => -10000, :currency => 'cad', :description => 'potato', :type => 'discount' }
],
```
(`type` should be moved to the beginning of the array.)
The purpose of this change is to give users better feedback when they
run into an encoding problem like this one. Currently, they just get
something confusing from the server, and someone on support usually
needs to examine a request log to figure out what happened.
CI will fail until the changes in #453 are brought in.
This moves away from rest-client's convention of using symbols as header
names so as to present less obfuscation as to how these are actually
named when they go over the wire.
Because headers can be injected via the bindings' API I was initially
worried that this change might break something, but upon inspection of
rest-client source, I can see now that headers take precedence as
assigned by their insertion order into the header hash, and are
"stringified" in that same loop [1]. This means that even if a user
injects a symbolized header name (`:idempotency_key`), it will still
correctly overwrite the one generated by stripe-ruby despite that using
the string format (`"Idempotency-Key"`).

Alphabetizing maps being encoded by key can cause problems because the
server side Rack relies on the fact that that a new array item will
start with a repeated key.
For example, given this encoding:
```
items: [
{ :type => 'sku', :parent => 'sku_94ZYSC0wppRTbk' },
{ :type => 'discount', :amount => -10000, :currency => 'cad', :description => 'potato' }
],
```
We need to have `type` appear first so that an array boundary is
recognized. So the encoded form should take:
```
items[][type]=sku&items[][parent]=...&items[][type]=discount&items[][amount]=...
```
But currently `type` gets sorted to the back, so we get something more
like:
```
items[][parent]=...&items[][type]=...&items[][amount]=...&items[][currency]=...&items[][description]=...&items[][type]=potato
```
Which the server will receive as this:
```
items: [
{ :type => 'sku', :parent => 'sku_94ZYSC0wppRTbk', :amount => -10000, :currency => 'cad', :description => 'potato' }
{ :type => 'discount' }
],
```
Here we remove the alphabetization to fix the problem and correct a bad
test.
Two changes:
1. The HTTP retry path has been refactored to make retries on errors
that are not RestClient exceptions possible by bringing the logic up a
level. This also has the effect of somewhat simplifying the exception
handling logic which can be somewhat difficult to reason about right
now.
2. Retry on `RestClient::Conflict` (a 409 from the API) as discussed in
issue #431.
Fixes#431.
Introduce a `#save_with_parent` flag that allows the default behavior of
never saving API resources nested under a parent to be overridden, a
feature that we so far only know to need for updating a source under a
customer.
CI is failing for a number of Ruby versions because shoulda is pulling
in should-matchers, which then pulls in activesupport. activesupport's
new 5.0.0 version is being picked up, and that requires at least Ruby
2.2.2.
Luckily the solution is easy, we're not using shoulda-matchers, only
shoulda-context, so just tighten up our dependencies a little and the
problem goes away.
* Rename the `Update` operation to `Save`
* Add the `update` class method to all saveable resources
* Add tests for update method
* Add tests for plans, invoice items, and application fees
* allow subs to be retrieved & created with new v1/subs API endpoint
* edit tests to check for url
* fix customer subscription URLs to go through v1/customers
- When performing requests on the behalf of a managed account, `stripe_account` option must be passed everytime, this can become redundant
- Allowing to set the `stripe_account` globally makes thing easier for wrapping every request in a single method, the same way as it is for defining the `api_key` globally
I'm not sure exactly what changed here (did we change the `$VERBOSE`
setting?), but I'm not seeing a whole lot of warnings when running the
test suites locally and in CI. For example:

Most of these are due to unused or uninitialized variables. This patch
fixes all warnings by fixing offending code.
This is consistent with API library behavior in other languages, and with our
API documentation (which doesn't mention needing to handle this type of error).
Prior to my last major serialization refactor, there was a check in the
code that would remove any subobjects from serialization that were of
their own proper resource type (for example, if a charge contained a
customer, that customer would be removed).
What I didn't realize at the time is that the old serialization code had
a bug/quirk that would allow *certain types* of subobjects that were API
resources to make it through unscathed.
In short, the behavior requirement here is *directly* contradictory.
There was a test in place that would make sure that `customer` was
removed from this hash:
``` ruby
{
:id => 'ch_id',
:object => 'charge',
:customer => {
:object => 'customer',
:id => 'customer_id'
}
}
```
But, as reported in #406, we expect, and indeed need, for `source` (a
card) to make it through to the API in this hash:
``` ruby
{
:id => 'cus_id',
:object => 'customer',
:source => {
:object => 'card',
:id => 'card_id'
}
}
```
My proposal here is to just remove the check on serializing API
resources. The normal code that only sends up keys/hashes that have
changed is still in place, so in the first example, `customer` still
isn't sent unless the user has directly manipulated a field on that
subobject. I propose that in those cases we allow the API itself to
reject the request rather than try to cut it off at the client level.
Unfortunately, there is some possibility that removing those API
resources is important for some reason, but of course there's no
documentation on it beyond the after-the-fact post-justification that I
wrote during my last refactor. I can't think of any reason that it would
be too destructive, but there is some level of risk.
In #394 we renamed `url` to `resource_url` in order to prevent name
collisions in API resource that also have a `url` property.
Unfortunately, this didn't account for the fact that when making API
calls on a list object we rely on a returned `url` property to build a
request, and this had been renamed to `resource_url`. Test should have
caught this, but they were written to work differently than how live
API calls actually function.
This patch repairs the problem by adding a `resource_url` to list
objects, and modifies test to be more accurate to reality so that
they'll catch this class of problem in the future.
Fixes#395.
This pull does two major things:
1. Refactors `serialize_params` to be more concise and readable while
still complying to our existing test suite. Unfortunately over time
this method has become a ball of mud that's very difficult to reason
about, as recently evidenced by #384.
2. Moves `serialize_params` from class method to instance method (while
still keeping for old class method for backwards compatibility). This
is to give it a more sane interface.
