Authentication error

[j0sephandres1987]

My mistake begins very early, mp_client = MercadoPago::Client.new(client_id, client_secret) i enter my clien_id and my client_secret but it's returned a 500 error.

PS: I'm working on a ruby on rails app.

Hi Joseph,

I'm not sure if you indeed have a problem or not. Are you trying to use the Client.new but always the server respond a 500 error?.

The problem there is, this lib don't have a Client class inside the MercadoPago module. In fact the lib don't have a MercadoPago module. The module name is Mercadopago, maybe you are confuse with another gem. This is an extract from the documentation:

Usage like SDK

For normal use

mp_client = Mercadopago::Sdk.new(client_id, client_secret)

Accept a optional parameter true or false to activate sandbox mode

sandbox_client = Mercadopago::Sdk.new(client_id, client_secret, true)

I think the best here is read the actual documentation of this gem.

[j0sephandres1987]

Right, the Clien class it is from another gem, sorry but still following the intruccions gaven here it doesn't works for me

[highercomve]

Excellent now we are in the same page, what is the problem?. When you use the Mercadopago::Sdk.new(client_id, client_secret) you get an error? Can you paste the error?

[j0sephandres1987]

----------------------------------In the controller:----------------------------

client_id = 'XXXX'
client_secret = 'XXXX'

mp_client = Mercadopago::Sdk.new(client_id, client_secret)
data = {
    :items => [
        {
            :title => "Title of product",
            :currency_id => "VEF",
            :unit_price => 2000.50,
            :quantity => 2,
        }
    ]
}
@preference = mp_client.create_checkout_preference(data)

---------------------in the view------------------------------------------- Pay

-------------------------the error--------------------------------- 500 Error interno del servidor El Servidor Web no puede realizar esta solicitud. Por favor, inténtelo de nuevo más tarde.

[highercomve]

Ok, the respond to that petition is:

@preference = mp_client.create_checkout_preference(data)
=> {"message"=>"currency_id invalid",
 "error"=>"invalid_items",
 "status"=>400,
 "cause"=>[],
 :code=>400}

I think that maybe your client_id and secret are from another country and not from Venezuela and Therefore the API don't let you use VEF like currency_id. You have to be sure that your client_id and secret are for mercadopago Venezuela in order to use 'VEF'.

Check here if you are using the correct credentials.

[j0sephandres1987]

i'm forn colombia

def mercado_pago_checkout client_id = 'xxxx' client_secret = 'xxxx'

mp_client = Mercadopago::Sdk.new(client_id, client_secret)
data = {
    :items => [
        {
            :title => "Title of product",
            :currency_id => "COP",
            :unit_price => 2000.50,
            :quantity => 2,
        }
    ]
}
preference = mp_client.create_checkout_preference(data)
return preference

end

but still: 500 Error interno del servidor

[j0sephandres1987]

i tried the php class from the official api and it works perfectly. but in my rails app don't

[highercomve]

But the error in rails is related to that?, because i use your credential and test with your data and get.

[j0sephandres1987]

well, the screen that shows the 500 error is not a typical rails error page, it's not from my app in fact

[j0sephandres1987]

How do you usually get to rectify that response?

[highercomve]

Can't you paste the rails log? in that way i can maybe see the error.

I just use your credentials from the console, and work like you see. In fact i just copy and paste your code.

[j0sephandres1987]

there is not rails log as usual when you get an error, this is the screen

[highercomve]

The error most be in the RubyMine console log. Or in the app folder on logs/development. Rails always has a log for the application on development with all the details.

[j0sephandres1987]

a lot of: Started GET "/store/show_cart" for 127.0.0.1 at 2015-09-28 23:39:23 -0500 Processing by StoreController#show_cart as HTML Completed 500 Internal Server Error in 5ms

[j0sephandres1987]

in chrome console: Failed to load resource: the server responded with a status of 500 (Internal Server Error)

[highercomve]

you have your log level in :debug? inside the config/enviorments/development.rb? If you set the app for :debug you can see a better track of the error.

For more info debugging a Rails App

[j0sephandres1987]

yes, config.assets.debug = true

[highercomve]

No, that variable set the debug on the assets precompilation system. That is not the debug level of the app in self.

The variable is this.

# See everything in the log (default is :info)
config.log_level = :debug

[j0sephandres1987]

after add config.log_level = :debug and restart the server: Started GET "/store/show_cart" for 127.0.0.1 at 2015-09-29 00:01:53 -0500 Processing by StoreController#show_cart as HTML Completed 500 Internal Server Error in 7ms , it is the same log

[highercomve]

In the same environment that the application is running? i think the application is running on production and the configuration is in development

[j0sephandres1987]

"Rails 4.1.8 application starting in development on http://0.0.0.0:3000"

[highercomve]

start Rails console, and test the same code in the console. In that way we can see the error that return mercadopago (if rails log is not returning anything).

[j0sephandres1987]

Ok, something very rare, when I intentionally added a syntax error. no longer get a screen normal rails with the description and log the error, but this although in the rails console log it shows the real error.

[highercomve]

And what is the real error? You don't have another application running in the port 3000 by any chance?

[j0sephandres1987]

I mean aside the issue of mercadopago, any error, not shown in the framework itself but the screen i don't know where it comes from.

[j0sephandres1987]

running the code on the console, it works perfectly, I get the response data as indicated the gem intructions

[highercomve]

It have to be a syntax error. The strange is that the Ruby Server is not taking the configuration. Because that error 500 is like a full HTML error and that error only is for production, the normal rails error show the trace error. I don't know if this variable is set to false in some place in your config/environment or config/application, but in development that variable must be true.

config.consider_all_requests_local = false

[j0sephandres1987]

solved!!! delete the others MercadoPago gems that had installed, the folders, the files from the rails folder installation, all that, and now it works, Thank you for all of your help, I really appreciate,

[highercomve]

Perfect!!! Excellent, your welcome the is no problem. I will close the issue. If you have another problem with the gem you can start another issue.

Have fun with the code and the force be with you

[j0sephandres1987]

thanks
