Ruby on Rails 5.0.2 - 多个嵌套Json渲染

我在尝试渲染json中的多个嵌套对象时遇到了一些麻烦。Ruby on Rails 5.0.2 - 多个嵌套Json渲染

这里是我的脚本

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

这工作，直到：product_sale，但是任何事情之后被忽略。

我需要的是包括：product_sale和：退款与嵌套属性。

谢谢！

我已经成功地使其工作！

的解决方案是替代在包括所述阵列，并使其像一个对象。

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

我不知道为什么发生这种情况，但现在正在工作！实际上，将=>更改为：并不是一个坏主意。

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

也许这是一个愚蠢的观察，但你尝试改变你的=>到:

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

与试过渲染JSON：销售点，包括：[：discount_sale，：offer_sale，：mixed_payment，product_sale：{包括：{product_history：{包括：产品}}}，退款：{包括：refund_products }] 但它是相同的响应=（ –
