headers in twriteJSONField

[Anonymous]

Hi,

I'm trying to use the tWriteJSONField component.

It's doing what i want but i don't have the headers in my rows.

The process is pretty simple but i don't understand where i do something wrong

tWriteJSON

And here is the result

{"trucks":["VO","K 360 IB4X2NB",["01483","CARROSSERIE","HIGER",[]],["00448","CONFIGURATION ESSIEUX","4X2",[]],["01503","CARROSSERIE","HIGER",[]],["06526","ORDINATEUR DE BORD","AFFICHAGE KM/H",[]],["02471","NIVEAU EMISSION","EEV",[]],["02301","ORDINATEUR DE BORD","AFFICHAGE KM/H",[]],["00668","PNEUMATIQUES 2E ESSIEU AR","295/80 R22.5",[]],["00666","PNEUMATIQUES ESSIEU AV","295/80 R22.5",[]],["00111","RETARDER","SCANIA",[]],["00020","BLOCAGE DIFFERENTIEL","AVEC",[]]]}

why i don't have my headers in my json?

The problem came from the "array" i read too much solutions and fused them too much

Hello,

I resolved your problem, inspire you from my config :

i have seen you have null values wrote with 2 brackets "[]", avoid this by setting a class attribute to object to the fields that might be null, else services who will use your data will struggle

Here is the json result given :

{
	"trucks": {
		"type": "VO",
		"model": "K 360 IB4X2NB",
		"caracteristiques": [
			{
				"carac1": "01483",
				"carac2": "ESSIEUX",
				"carac3": "BLISFER",
				"carac4": null
			},
			{
				"carac1": "01783",
				"carac2": "ODB",
				"carac3": "COMPTEUR KMH",
				"carac4": null
			},
			{
				"carac1": "01413",
				"carac2": "CHASSIS",
				"carac3": "FONTE",
				"carac4": null
			}
		]
	}
}
