Hello, How can i range in a conditionnal array ? Here my code where I filter the results of the table by city {{ $city := .Params.cityName }} {{ range := .Site.Data.petiteannonce }} {{ $cityName := .cityName }} {{ if eq $city $cityName }} but i just want the first three results. I’ve tried wit…

Try the following: {{ range := .Site.Data.petiteannonce }} {{ if .cityName | eq .Params.cityName }} // do something {{ end }} {{ end }}

To be more precise (excuse my french :slight_smile: ) my first block of code is correct but i have all the result. My issue is i just want the first 3 elements like {{ range first 3 }}

Then try the following: {{ $cities := where .Site.Data "petiteannonce" "eq" .Params.cityName }} {{ range first 3 $cities }} // do something {{ end }} {{ end }} where allows you to filter a collection, e.g. with the equal operator (here eq). I haven’t tested the code above but it should direct you…

Could you post an excerpt of your JSON?

Traveling and on phone, so preemptive apologies @digitalcraftsman and @jonathanulco , but can the above be put into a one-liner: {{ range first 3 (where .Site.Data.petiteannonce "eq" .Params.cityName) }} Your code {{ end }}

Here an excerpt of the jSon https://pastebin.com/0h3m3T3R and there’s 9 Bordeaux for your test :wink:

Please share a pretty printed version of the JSON next time. Otherwise it’s hard to read. :wink: I guess .Site.Data.petiteannonce equals the posted array of objects, right? Give this a try: {{ range first 3 (where .Site.Data.petiteannonce "cityName" "eq" .Params.cityName) }} Your code {{ end }} …

/bow @digitalcraftsman , thanks you !
