## INSTALL
|
||||
|
||||
gem 'paiement_cic'
|
||||
script/plugin install git://github.com/novelys/paiementcic.git
|
||||
|
||||
or, in your Gemfile
|
||||
|
||||
gem 'paiement_cic', :git => 'git://github.com/novelys/paiementcic.git', :branch => 'gem'
|
||||
|
||||
## USAGE
|
||||
|
||||
### in an initializer (`config/initializers/paiement_cic.rb`) :
|
||||
### in environment.rb :
|
||||
|
||||
```ruby
|
||||
PaiementCic.default_config.configure do |config|
|
||||
# here the hmac key calculated with the js calculator given by CIC
|
||||
config.hmac_key = "########################################"
|
||||
PaiementCic.hmac_key = "########################################"
|
||||
# Here the TPE number
|
||||
config.tpe = "#######"
|
||||
PaiementCic.tpe = "#######"
|
||||
# Here the Merchant name
|
||||
config.societe = "xxxxxxxxxxxxx"
|
||||
PaiementCic.societe = "xxxxxxxxxxxxx"
|
||||
|
||||
# You can specify the target URL
|
||||
config.target_url = "https://ssl.paiement.cic-banques.fr/test/paiement.cgi"
|
||||
# Or used predefined ones by specifying environment and bank
|
||||
config.bank = :cm # or :cic
|
||||
config.env = :test # or :production
|
||||
end
|
||||
```
|
||||
### in development.rb :
|
||||
|
||||
You can also specify different attributes when initializing `PaiementCic::TPE` and with `paiement_cic_hidden_fields` helper by passing an hash.
|
||||
```ruby
|
||||
{
|
||||
hmac_key: "########################################",
|
||||
tpe: "#######",
|
||||
societe: "xxxxxxxxxxxxx",
|

||||
PaiementCic.target_url = "https://ssl.paiement.cic-banques.fr/paiement.cgi" # or https://paiement.creditmutuel.fr/paiement.cgi
