Ruby on Rails 5.0.2 - 多個嵌套Json渲染

我在嘗試渲染json中的多個嵌套對象時遇到了一些麻煩。Ruby on Rails 5.0.2 - 多個嵌套Json渲染

這裏是我的腳本

def getFullSale 
     sale = Sale.find(params[:id]) 
     render json: sale, include: [:discount_sale, :offer_sale, :mixed_payment, :product_sale => {:include => {:product_history => {include: :product}}}, :refunds => {include: :refund_products}] 
end

這工作，直到：product_sale，但是任何事情之後被忽略。

我需要的是包括：product_sale和：退款與嵌套屬性。

謝謝！

我已經成功地使其工作！

積分在Here

的解決方案是替代在包括所述陣列，並使其像一個對象。

def getFullSale 
    sale = Sale.find(params[:id]) 
    render json: sale, include: {discount_sale: {}, offer_sale: {}, mixed_payment: {}, :product_sale => {:include => {:product_history => {include: :product}}}, :refunds => {include: :refund_products}} 
end

我不知道爲什麼發生這種情況，但現在正在工作！實際上，將=>更改爲：並不是一個壞主意。

def getFullSale 
    sale = Sale.find(params[:id]) 
    render json: sale, include: {discount_sale: {}, offer_sale: {}, mixed_payment: {}, product_sale: {include: {product_history: {include: :product}}}, refunds: {include: :refund_products}} 
end

也許這是一個愚蠢的觀察，但你嘗試改變你的=>到:

json: sale, include: [:discount_sale, :offer_sale, :mixed_payment, :product_sale : {:include : {:product_history : {include: :product}}}, :refunds : {include: :refund_products}]

與試過渲染JSON：銷售點，包括：[：discount_sale，：offer_sale，：mixed_payment，product_sale：{包括：{product_history：{包括：產品}}}，退款：{包括：refund_products }] 但它是相同的響應=（ –
