The idea was to query a dataset with querystring params. I only want the "records" to match only what was queried.
Dataset
{
1111:
{
Category: "Education"
Role: "Analyst"
}
2222:
{
Category: "Communications and Media"
Role: "Analyst"
}
3333:
{
Category: "Public Sector"
Role: "Something else"
}
4444:
{
Category: "Public Sector"
Role: "Something else"
}
...
}
[[Prototype]]: Object
I'm sending in qString
Category: (2) ['Communications and Media', 'Education']
Role: ['Analyst']
length: 0
[[Prototype]]: Array(0)
I'd like to loop over that and filter/reduce so I only have records that match. Sort of an and instead of an or.
dataSet is an Object of objects. Thoughts? Thanks in advance.
export const Filtered = (qStrings, dataSet) => {
const filtered = [];
Object.entries(qStrings).forEach(([field]) => {
qStrings[field].forEach((value) => {
filtered.push(
..._.filter(dataSet, (sess) => {
if (sess[field] && sess[field].toString() === value.toString()) {
return sess;
}
})
);
});
});
return _.uniq(filtered);
};
geez, I figured it out with a colleague who's way smarter than me wink Jess!
export const Filtered = (qStrings, dataSet) => {
let filtered = [];
Object.entries(qStrings).forEach(([field], idx) => {
let source = filtered;
if (idx === 0) {
source = dataSet;
}
filtered = _.filter(source, (sess) => {
return sess[field] && sess[field].includes(qStrings[field]);
});
});
return _.uniq(filtered);
};
Now to clean this up.
Not sure if this solves your problem exactly, but you can apply this logic without mutation for a much cleaner function.
export const matches = (qStrings, dataSet) =>
Object.entries(dataSet).reduce((acc, [key, value]) =>
Object.entries(value).every(([rKey, rValue]) => qStrings[rKey]?.includes(rValue))
? { ...acc, [key]: value }
: acc,
{});
This will return records 1111 and 2222 because they match one of the categories and the role in qStrings.
