Including other one jbuilder template in another

Question

Consider the following show.json.jbuilder template:

json.user do |json|
    json.extract! @user, :id, :username, :email, :created_at, :avatar
end

json.policies do |json|
    json.array!(@policies) do |policy|
        json.extract! policy, :id, :title, :cached_votes_score
    end
end

json.liked do |json|
    json.array!(@liked) do |policy|
        json.extract! policy, :id, :title, :cached_votes_score
    end
end

json.disliked do |json|
    json.array!(@disliked) do |policy|
        json.extract! policy, :id, :title, :cached_votes_score
    end
end

Would it be possible to split those up into four different templates, and then just include them in the show template? Something like:

include template_user
include template_policies
include template_liked
include template_disliked

If this is not possible, what alternatives exist for creating more modular jbuilder code? I find my jbuilder code very un-DRY.

Answer 1

Yes. Is possible. Split your files like:

_user.json.jbuilder

json.user do |json| json.extract! @user, :id, :username, :email, :created_at, :avatar end

_policies.json.jbuilder

json.policies do |json| json.array!(@policies) do |policy| json.extract! policy, :id, :title, :cached_votes_score end end

_liked.json.jbuilder

json.liked do |json| json.array!(@liked) do |policy| json.extract! policy, :id, :title, :cached_votes_score end end

_disliked.json.jbuilder

json.disliked do |json| json.array!(@disliked) do |policy| json.extract! policy, :id, :title, :cached_votes_score end end

and then you can simply join them with:

show.json.jbuilder

json.partial! 'user' json.partial! 'policies' json.partial! 'liked' json.partial! 'disliked'

But I would suggest to improve them a little bit and write them using local variables and so:

_user.json.jbuilder

json.user do |json| json.extract! user, :id, :username, :email, :created_at, :avatar end

and you include it passing the user as an argument:

json.partial! 'user', user: @user
