Generate a Nested JSON Array in Jbuilder

Generate a nested JSON array in JBuilder

I'm not sure which attributes your product can have but i would try something like:

if @condition
 json.code :success
 json.array!(@branches) do |json, branch|
   json.(branch, :id, :branch_name, :barcode)
   json.menus branch.menus do |json,menue|
     json.id menue.id
     json.menu_name menue.menu_name
     json.products menue.products do |json, product|
       json.product_attribute_1 product.product_attribute_1
     end
   end
 end
else
  json.code :error
  json.message 'Mensaje de error'
end

i'm also not quite sure why you try to nest @branches under a branch as stated by:

json.branch do
   ...
end

i just removed that.

Constructing a nested JSON request with Jbuilder

ARG. Ok so this code is perfectly right. The issue was that I"m using the Gon gem in conjunction with Jbuilder, and Request is a predefined class in Gon.

So just changed code to

@requestrecords.select....

And in the controller:

@requestrecords = Request.all

Using jbuilder to access child objects in has many relationship

Ok this worked:

#/test.json.builder

json.array!(@lenders) do |json, lender|
  json.(lender, :id, :email, :latitude, :longitude)
  json.inventories lender.inventories do |json, inventory|
    json.(inventory, :id, :itemlist_id, :description)
  end
end

Need to create a json string from Jbuilder in rails Helper

Can you try with:

ApplicationController.render(template: 'demandes/index', assigns: { demandes: @demandes })

(Substitute with your template name)

You should probably split your code into three files. First create a partial from your code above, you could name it eg _trip.json.jbuilder:

json.name trip.name
json.title trip.name
json.start_date trip.start_date
json.end_date trip.end_date
json.start trip.start_date
json.end trip.end_date
json.allDay true
if ActiveRecord::Type::Boolean.new.cast(params[:show_visits]) == true
    json.visits trip.visits.each do |visit|
        json.date visit.date.to_date.day.ordinalize + " " + visit.date.to_date.strftime("%b %Y")
        json.park visit.park.name
        json.first_on_trip visit.first_on_trip?
        json.last_on_trip visit.last_on_trip?
        # json.gallery visit.has_gallery? ? url_for(visit.album) : false
        if visit.park.has_location?
            json.park_lat visit.park.lat
            json.park_lng visit.park.lng
        end
    end
end

I also removed instance variable and replaced it with local one. Now you can create two views where you use this partial, one for the calendar and second for the other place:

calendar.json.jbuilder

json.array! [@trip] do |trip|
  json.partial! "path/to/trip", locals: { trip: trip }
end

other_place.json.jbuilder will be even easier:

json.partial! "path/to/trip", locals: { trip: @trip }

For the exact partial rendering code please see the jBuilder documentation. It may be a bit more complicated or even easier based on location of these files in the views.

You could probably use instance variable directly in the partial, but this solution makes it a little bit more general and therefore the partial can be used in more different contexts.
