Malformed params creation on POST when params added to body

[pbelouin-mpiwg]

Hello,

Thanks a lot for that gem, it's great! I have a small issue however, and cannot figure out what is going on; I have the following spec code to test a sessions controller:

  path '/api/sign_in' do
    post 'Sign In' do
      tags 'Sessions'
      produces 'application/json'
      parameter name: :credentials, in: :body, description: 'The credentials of the user', schema: {
        type: :object,
        properties: {
          email: { type: :string },
          password: { type: :string }
        },
        required: ['email', 'password']
      }
      response '200', 'User successfully logged in' do
        let(:user) { create(:user, password: 'password') }
        let(:credentials) { { email: user.email, password: 'password' } }
        run_test!
      end
    end
  end

it works as expected, however the params arrive to my app in this form:

<ActionController::Parameters {"{\"email\":\"america.braun@hanewisoky.name\",\"password\":\"password\"}"=>nil, "format"=>:json, "controller"=>"api/v1/sessions", "action"=>"create"} permitted: false>

As you can see, I end up with params in a weird form, i.e

{\"email\":\"america.braun@hanewisoky.name\",\"password\":\"password\"}"=>nil 

which makes me unable to extract them from the params to perform my sign up mechanism - what is weird is that with the generated documentation, when using the "try it" feature, the params are actually sent properly. Would you have an idea about how I could get this sorted? Thanks a lot in advance!!

This is how the params are formed when I use the "try it" feature:

<ActionController::Parameters {"email"=>"string", "password"=>"string", "format"=>:json, "controller"=>"api/v1/sessions", "action"=>"create", "session"=>{"email"=>"string", "password"=>"string"}} permitted: false>

As you can see, it's all hunky dory in this case :\

Damn! I needed to set the "consume" value to 'application/json'! I'll close the issue but leave that here just in case somebody googles it, if that's ok.

I've a similar issue but consumes is set to application/vnd.api+json (I tried application/json too). The result is quite similar to yours:

<ActionController::Parameters {"{\"data\":{\"type\":\"bank_accounts\",\"attributes\":{\"bank_id\":\"some_uuid\",\"login\":\"my_login\",\"password\":\"my_password\"}}}"=>nil, "format"=>:json, "controller"=>"bank_accounts", "action"=>"link"} permitted: false>

Here is my code. What am I missing?

path '/bank_accounts/link' do
  
    get 'Create a link between a bank and the Bank API' do
      consumes 'application/vnd.api+json'
      produces 'application/vnd.api+json'
      
      parameter name: :params,
                in: :body,
                description: 'data of the futur bank account',
                required: true,
                schema: {
                  type: :object,
                  properties: {
                    data: {
                      type: :object,
                      properties: {
                        attributes: {
                          type: :object,
                          properties: {
                            bank_id: {
                              type: :string,
                              format: 'uuid',
                              description: 'ID of a bank',
                              example: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'
                            },
                            login: {
                              type: :string,
                              description: 'Login of the user to connect to the selected bank'
                            },
                            password: {
                              type: :string,
                              description: 'Password of the user to connect to the selected bank'
                            }
                          }
                        },
                        type: {
                          type: 'string',
                          description: 'bank_accounts'
                        }
                      }
                    }
                  }
                }
    
      describe 'with valid parameters' do
        response '200', 'Create a bank account linked to the bank' do
          let(:params){ { data: {type: 'bank_accounts', attributes: {bank_id: 'some-uuid',
                                                                  login: 'my_login',
                                                                   password: 'my_password'} }}}

          schema '$ref' => '#/definitions/BankAccount'
        
          run_test!
        end
end

Edit: I've switched from get to post and it's working like a charm. Thanks for your issue. It helped a lot!
