Calling function in truffle console error

Question

How do I correctly call a function of a contract that in the truffle console?

Using the petshop example project, I migrated the contract onto the network successfully.

In the truffle console I executed:

var ad = Adoption.deployed()

This yields the reply:

undefined

When I execute ad.adopt(23); adopt being the function name and 23 being the unit parameter; I get the exception TypeError: ad.getAdopters is not a function

What was my mistake in calling the function?

Thanks!

Answer 1

Inside Truffle console

ContractName.deployed().then(function(instance){app = instance})
app.adopt(23)//call method on contract class

Try this inside your app.

//from App.js
App.contracts.SmartContractName.deployed().then(function(instance){
   return instance.adopt(23)//call method on contract class
}).then(function(){

}).catch(function(err){
   console.log(err);
})
