I have 2 filter functions exported from helpers.js file:
export const filterSource = (data, source_tags_array) => {
let accumulator = []
source_tags_array.forEach( tag => {
accumulator = data.filter( event => {return event.source_type.includes(tag)})
// accumulator.concat(...tmp)
})
accumulator.sort(function(a,b) {
return new Date(b.date) - new Date(a.date)
})
return accumulator
}
export const filterTags = (data, tags_array) => {
let accumulator = []
tags_array.forEach( tag => {
data.forEach((event) => {
if (!accumulator.some(el => el.id === event.id) && event.tags.includes(tag)) {
accumulator.push(event)
}
})
return accumulator
})
}
And I import them in reducer file:
import * as helpers from "../helpers";
export const filter = events_data => {
return (dispatch, getState) => {
const { access_tags, access_source_tags} = getState().user
const filteredSource = helpers.filterSource(events_data, access_source_tags)
const events = helpers.filterTags(filteredSource, access_tags)
dispatch(fetchEventsSuccess(events))
}}
While first one (filterSource) works fine the second (filterTags) is undeifned
Screenshot with variables values from debuger
In case you cannot see image... filteredSource: Array(160) events_data: Array(395) accesss_source_tags: Array(1) access_tags: Array(1) events: UNDEFINED
The accumulator from filterTags in helpers.js on return point is Array(65) but for some reason after import is undefined ...
I tried named imports as well... same problem.
Any ideas?
The return
inside filterTags
is inside the forEach
, move it outside and it should work
export const filterTags = (data, tags_array) => {
let accumulator = []
tags_array.forEach( tag => {
data.forEach((event) => {
if (!accumulator.some(el => el.id === event.id) && event.tags.includes(tag)) {
accumulator.push(event)
}
})
})
return accumulator
}
