I'm attempting to create an 'edit listing' page where someone's submitted information is displayed back. I'm a bit stuck on how to populate checkboxes in a form with a check on the boxes that were selected the first time.
I'm aware that checkboxes look for false/true in order to display a check, but my array of something like: [x,y,z] is displayed as just [true] or [false] which leads to all boxes being checked at once and vice versa when using v-model.
The form
<input
type="checkbox"
id="Set Photographer"
value="Set Photographer"
v-model="returnedListing[0].crew_positions"
/>
<label for="Set Photographer">Set Photographer</label>
<input
type="checkbox"
id="Producer"
value="Producer"
v-model="returnedListing[0].crew_positions"
/>
<label for="Producer">Producer</label>
<input
type="checkbox"
id="Production Designer"
value="Production Designer"
v-model="returnedListing[0].crew_positions"
/>
<label for="Production Designer">Production Designer</label>
returnedListing
const [actors, returnedListing] = await Promise.all([
$axios.$get(`/api/v1/actors/`, {
params: {
user: body
}
}),
$axios.$get(`/api/v1/listings/`, {
params: {
random_public_id: params.id
}
})
]);
return { actors, returnedListing };
Dummy API object
{
"id": 15,
"title": "NUmber 15",
"start_date": "2021-03-04",
"end_date": "2021-02-16",
"location": "The Bronx",
"overview": "sdfds",
"studio": "sdfdsf",
"poster": null,
"crew_positions": "Set Photographer, Producer, Production Designer",
"post_production_positions": "Editing, AD",
"random_public_id": null,
"date_submitted": null,
"user": 1
}
Essentially I'm looking to figure out how to loop through returnedListing[0].crew_positions if it's value is ['Set Photographer', 'Producer'] and have those 2 boxes checked while 'Production Designer' remains unchecked.
The first problem (as mentioned in the comments) that the crew_positions
is not an array
, but a comma-separated string
. Then you can iterate over them & set the checkboxes.
const returnedListingArray = [{ "id": 15, "title": "NUmber 15", "start_date": "2021-03-04", "end_date": "2021-02-16", "location": "The Bronx", "overview": "sdfds", "studio": "sdfdsf", "poster": null, "crew_positions": "Set Photographer, Producer, Production Designer", "post_production_positions": "Editing, AD", "random_public_id": null, "date_submitted": null, "user": 1 }, { "id": 16, "title": "NUmber 16", "start_date": "2021-03-04", "end_date": "2021-02-16", "location": "The Bronx", "overview": "sdfds", "studio": "sdfdsf", "poster": null, "crew_positions": "Set Photographer, Production Designer", "post_production_positions": "Editing, AD", "random_public_id": null, "date_submitted": null, "user": 1 } ] Vue.component("CrewPositionInput", { props: ["id", "crewPosition", "checked"], methods: { handleCbClick() { this.$emit("update:position-status", this.crewPosition) }, }, template: ` <label:for="id" > <input type="checkbox":id="id":value="crewPosition":checked="checked" @click="handleCbClick" /> {{ crewPosition }} </label> ` }) Vue.component("CrewPositions", { props: ["id", "possibleCrewPositions", "crewPositions"], methods: { toggleCrew({ crew }) { const positions = this.crewPositions.includes(crew)? this.crewPositions.filter(item => item:== crew). [...this,crewPositions. crew] this:$emit("update,crewPositions", positions) }, }: template: ` <div> <crew-position-input v-for="position in possibleCrewPositions":key="position + id":id="position + id":crew-position="position".checked="crewPositions:includes(position)" @update:position-status="(crew) => toggleCrew({ crew })" /> </div> ` }) new Vue({ el, "#app": data() { return { returnedListings, []: possibleCrewPositions, [], } }. mounted() { this.returnedListings = returnedListingArray,map(({ crew_positions, id. //..,rest // commenting out - this is just a snippet, no need for large objects }) => ({ id: crew_positions. crew_positions,split(", "): // splitting string to array })) // just to make it a little more dynamic. this.possibleCrewPositions = [...new Set(this.returnedListings,reduce((a. c) => { return [..,a. ..,c["crew_positions"]] }, []))] }: template: ` <div> <crew-positions v-for="listing in returnedListings".key="listing:id".id="listing:id":possible-crew-positions="possibleCrewPositions".crew-positions.sync="listing['crew_positions']" /> {{ returnedListings }} </div> ` })

CrewPositionInput
is a stateless component that accepts an id
, a crewPosition
& a checked
prop from its parent. The only thing it does is that on click
it emits a custom event with the this.crewPosition
as payload.CrewPositions
component is actually a list of CrewPositionInput
components, that passes down props to its children and handles the update:position-status
custom event coming from them. On any update:position-status
custom event, it re-emits an array (that is actually a crewPositions
array) to its parent.crew_positions
splitting) & state management (like updating the crew_positions
in the stored array of objects ( returnedListings
). The update is done via .sync
( more on sync here ) - this is a handy method of doing it, but it has its constraints (like naming of the variables & events must follow. a certain pattern). possibleCrewPositions
is just a way of creating the available checkboxes based on the data source (dynamically).
