What I'm trying to do is to receive an Array of numbers with the key entries.
entries: [1, 2, 3]
This docblock renders the following CURL.
curl -X POST "app.test/visa-entry/calculate" -H "accept: application/json" -H "Content-Type: application/json" -H "X-CSRF-TOKEN: " -d "[0]"
How can I get it to send the array with the key entries?
If you don't want the client to post the array directly in the request-body, but with a key, you'll need to specify the in=body parameter as type="object" and define the array as a property of that schema.
Like this:
/**
* #SWG\POST(
* path="/visa-entry/calculate",
* operationId="visaEntryCalculate",
* tags={"Visa Entry"},
* summary="Calculate the price for an array of visa entries",
* description="Calculate the price for an array of visa entries",
*
* #SWG\Parameter(
* in="body",
* name="json",
* description="Visa Entry IDs to calculate to total price",
* required=true,
* #SWG\Schema(
* type="object",
* #SWG\Property(
* property="entries",
* type="array",
* #SWG\Items(type="number")
* )
* ),
* collectionFormat="multi"
* ),
*
* #SWG\Response(
* response=200,
* description="OK"
* ),
*
* #SWG\Response(
* response=400,
* description="Bad request"
* ),
* )
*
* Calculates a visa entry

So, I have the following security vulnerability in activesupport, activerecord and actionpack.
Name: actionpack
Version: 5.2.8.1
CVE: CVE-2023-22792
GHSA: GHSA-p84v-45xj-wwqj
Criticality: Unknown
URL: https://github.com/rails/rails/releases/tag/v7.0.4.1
Title: ReDoS based DoS vulnerability in Action Dispatch
Solution: upgrade to '~> 5.2.8, >= 5.2.8.15', '~> 6.1.7, >= 6.1.7.1', '>= 7.0.4.1'
Name: activerecord
Version: 5.2.8.1
CVE: CVE-2022-44566
GHSA: GHSA-579w-22j4-4749
Criticality: Unknown

Name: activesupport
Version: 5.2.8.1
CVE: CVE-2023-22796
GHSA: GHSA-j6gc-792m-qgm2
Criticality: Unknown
URL: https://github.com/rails/rails/releases/tag/v7.0.4.1
Title: ReDoS based DoS vulnerability in Active Support’s underscore
Solution: upgrade to '~> 5.2.8, >= 5.2.8.15', '~> 6.1.7, >= 6.1.7.1', '>= 7.0.4.1'
my rails version from gemfile
gem 'rails', '~> 5.2.8', '>= 5.2.8.1'
as the solution suggests upgrade to '~> 5.2.8, >= 5.2.8.15' seems to be the next step. so I changed the gemfile as follows:
gem 'rails', '~> 5.2.8', '>= 5.2.8.15'
and then bundle install' | I've also done bundle update` which produces the same output as the following
Fetching gem metadata from https://rubygems.org/..........
Could not find gem 'rails (~> 5.2.8, >= 5.2.8.15)' in rubygems repository https://rubygems.org/ or installed locally.

What am I doing wrong. how can i upgrade those three (activesupport, activerecord and actionpack)?
After defining new rules and versions in your Gemfile, run:
bundle update rails
This will update all direct dependencies of Rails too.
But! be sure the version exists on RubyGems: https://rubygems.org/gems/rails/versions (it seems that v5.2.8.15 does not exist).
I am using "nelmio/api-doc-bundle" 4.9 and I need to pass multi-dimenional array using swagger. In postman I am passing like this.
So far, I have tried this in swagger.
* #OA\Parameter(
* name="banner[]",
* in="query",
* description="Banner information",
* required=true,
* #OA\Schema(
* type="array",
* #OA\Items(
* type="array",
* #OA\Items(type="string", propertyNames="startDate")
* )
* ),
* ),
i'm using Swagger to document my Lumen API and im using annotations. The thing is, i don't know how to achieve the structure that you can see on the picture with annotations
Can anyone help me with this?
I finally found the answer to this and how to get the structure that i wanted:
#OA\RequestBody(
* #OA\JsonContent(
* type="object",
* #OA\Property(property="idNumber", type="string"),
* #OA\Property(property="ClientId", type="string"),
* #OA\Property(property="inspection", type="array",
* #OA\Items(type="object", properties = {
* #OA\Property(property="Color", type="string"),
* #OA\Property(property="time", type="string"),
* #OA\Property(property="place", type="string"),
* #OA\Property(property="issue", type="string"),
* #OA\Property(property="details", type="string"),
* }),
* ),
* #OA\Property(property="detailId", type="string"),
* #OA\Property(property="WayPayment", type="array",
* #OA\Items(type="object", properties = {
* #OA\Property(property="banking", type="string"),
* #OA\Property(property="numbercard", type="string"),
* #OA\Property(property="numberpayment", type="string"),
* }),
* ),
* ),
* ),
I want to specify the default JSON body for a POST request in Swagger-PHP. My annotations look like this:
/**
* Setup order
*
* #SWG\Post(
* path="/order/setup",
* operationId="setupOrder",
* tags={"Orders"},
* summary="Setup an order with status draft.",
* description="Setup an order with status draft",
* consumes={"application/json"},
* #SWG\Parameter(
* name="body",
* in="body",
* default="{}",
* description="Json order info body (customer and products info)",
* required=true,
* #SWG\Schema(type="string")
* ),
* #SWG\Response(
* response=200,
* description="successful operation"
* ),
* #SWG\Response(response=400, description="Bad request"),
* security={
* {"api_key_security_example": {}}
* }
* )
*
*/
As you can see I'm trying to achieve the default value with default="{}", but Swagger UI ignores this value and places 'string' instead as default value:
How can I change the 'string' part to a default JSON object?
You can achieve as you expected by modifying your #SWG\Parameter().
Example (look at example of the property):
* #SWG\Parameter(
* name="body",
* in="body",
* description="User email used to create account.",
* required=true,
* #SWG\Schema(#SWG\Property(property="email", type="string", example="email#example.com")),
* )
You can use like below.
/**
* Setup order
* #SWG\Post(
* path="/order/setup",
* operationId="setupOrder",
* tags={"Orders"},
* summary="Setup an order with status draft.",
* description="Setup an order with status draft",
* consumes={"application/json"},
* #SWG\Parameter(
* name="body",
* in="body",
* default="{}",
* description="Json order info body (customer and products info)",
* required=true,
* #SWG\Schema(ref="#/definitions/testDefinitions")
* ),
* #SWG\Response(
* response=200,
* description="successful operation"
* ),
* #SWG\Response(response=400, description="Bad request"),
* security={
* {"api_key_security_example": {}}
* }
* )
* #SWG\Definition(
* definition="PlanResponse",
* example={
* "type":"string"
* }
* )

I have set up an example however the
y value is coming in as a negative value when it's supposed to be a positive value
and the coordinate space is looking like 300 square units after the conversion not 700 square units like things are supposed to be.
Also for some reason the
X and Y seem to be shifted a little bit out of place I'm not sure if this has to do with the canvas bounding rectangle. Does anyone know how to solve these issues?
My matrix library is the latest CDN of glMatrix. The idea is to click the canvas and get an alert to pop up.
Thank you!

1) y value is coming in as a negative value when it's supposed to be a
positive value
In openGL, [-1, -1] is in the bottom-left corner of the viewport, [1, 1] in the top-right corner. The Y coordinate increase "upward".
gluUnProject, specificaly, expect y=0 to be the bottom of the canvas.

2) and the coordinate space is looking like 300 square units after the
conversion not 700 square units like things are supposed to be.
You only set the canvas css size. There is no relationship between css size of the canvas and it's width and height properties.
The css size only used to "stretch" and display the canvas to a given size (like an img).
The width and height set the actual pixels resolution of the canvas.
Since it's not set, it's default size is 300x150. It's the values you use to set your otho matrix, thus the result you get when unproject.
3) X and Y seem to be shifted a little bit out of place I'm not sure
if this has to do with the canvas bounding rectangle. Does anyone know
how to solve these issues?
You use mouse event's clientX and clientY as input to unproject. It's mouse coordinates relative to the browser screen. You need to give coordinates relative to canvas. The shift come from the default html margin
