Ramda - 如何验证 object？

Question

I would like to refactor the code below using Ramda. I want to compare the list of keys and values with the data that I receive from the server, if the data matches, the function run. To do this, I created a list of keys and values and using include() I get a boolean .

//example data

data = { fieldName: 'secretKey', fieldValue: 'ymt' } 


const fieldNames = ['secretKey', 'activateCode']
const fieldValues = ['ymt', 'IdTYj']

if ( fieldNames.includes(data.fieldName) || fieldValues.includes(data.fieldValue)) {
    yield put(isLoading(true));
}

Instead of include() I used R.include but I always get false

const field = R.equals( fieldNames, data.fieldName) // return false

Which method in Ramda is more suitable for comparing keys and values to return a boolean ?

Answer 1

I think you're looking for where eg

const check = where({ username: either(equals('foo'), equals('FOO'))
                    , password: either(equals('bar'), equals('BAR'))});

check({username: 'foo', password: 'qux'}); // false
check({username: 'qux', password: 'bar'}); // false
check({username: 'foo', password: 'bar'}); // true
check({username: 'foo', password: 'BAR'}); // true
check({username: 'FOO', password: 'BAR'}); // true

Answer 2

I'd rather do something alike, You need to R.flip(R.includes) to use it within your algorithm

 const put = R.identity; const isLoading = R.identity; function* validate(data) { const keys = ['secretKey', 'activateCode']; const values = ['ymt', 'IdTYj']; const predicate = R.where({ fieldName: R.includes(R.__, keys), fieldValue: R.includes(R.__, values), }); if (predicate(data)) { yield put(isLoading(true)); } }; const iterator = validate({ fieldName: 'secretKey', fieldValue: 'ymt', }); console.log( iterator.next().value );
