我完全迷失了如何使这个请求通过ajax而不会丢弃406错误。我正在尝试使用ajax将项目添加到购物车,并且项目确实已添加,刷新后购物车会更新。我收到的所有内容都是xhr通知,其中包含406错误。任何帮助都非常感谢。
产品控制器
class ProductsController < ApplicationController
def index
@products = Shoppe::Product.root.ordered.includes(:product_categories, :variants)
@products = @products.group_by(&:product_category)
end
def show
@product = Shoppe::Product.root.find_by_permalink(params[:permalink])
end
def buy
@product = Shoppe::Product.root.find_by_permalink!(params[:permalink]) || params[:variant] ? Shoppe::Product.root.find_by_permalink!(params[:permalink]).variants.find(params[:variant].to_i) : @product
current_order.order_items.add_item(@product, 1)
respond_to do |format|
format.js
end
end
end
Show.html.erb
<h2><%= @product.name %></h2>
<% if @product.default_image %>
<%= image_tag @product.default_image.path, :width => '200px', :style => "float:right" %>
<% end %>
<p><%= @product.short_description %></p>
<p>
<% if @product.has_variants? %>
<% @product.variants.each do |v| %>
<%= form_tag product_path(@product.permalink, @product.permalink, :variant => v.id ),id: '#submit-form', remote: true do %>
<%= submit_tag 'Add to basket', :disabled => !v.in_stock? %>
<% end %>
<% end %>
<% else %>
<b><%= number_to_currency @product.price %></b>
<%= link_to "Add to basket", product_path(@product.permalink), :method => :post %>
<% end %>
</p>
<hr>
<%= simple_format @product.description %>
<hr>
<p><%= link_to "Back to list", root_path %></p>
的routes.rb
Rails.application.routes.draw do
mount Shoppe::Engine => "/admin"
get "product/:permalink", to: "products#show", as: "product"
post "product/:permalink", to: "products#buy", as: "buy"
get "basket", to: "orders#show"
delete "basket", to: "orders#destroy"
root to: "products#index"
end
products.js.erb
$(document).ready(function() {
var data = $('#submit-form').attr('action')
$.ajax({
type: 'POST',
url: data
});
});

查看format.js
的内容,我发现了这一点:rails respond_to format.js API
format.js
操作中的buy
似乎会呈现buy.js
文件。你还没有显示这个文件,所以我觉得它不存在。
我想知道你要做的是渲染json,这很简单。你可以替换:
respond_to do |format|
format.js
end
用这个:
render json: <your object>.to_json
确保在发送回复之前删除任何私人数据。
顺便说一句,您应该将回调附加到$.ajax
来电。
