Rails view 提交时，参数不知道参数哪里有问题，请帮看一下
代码如下：
<%= form_for @product, url: {action: "create"}, html: {:class => 'form-horizontal'} do |f| %>
<div class="row add-entity" style="display:none;">
<div>
<div class="col-sm-2">
<%= f.label :product_category_id %>
<%= f.select :product_category_id, options_from_collection_for_select(ProductCategory.all, :id, :name) %>
</div>
<div class="col-sm-2">
<label>价格</label>
<input class="form-control" type="text" name="price">
</div>
<div class="col-sm-8">
<label>装备名称</label>
<input class="form-control" type="text" name="title">
</div>
</div>
<h4 class="col-sm-12"><span class="brand"></span><span class="title"></span></h4>
<div class="col-sm-12">
<div class="thumbnail">
<img class="img-responsive entity-chief-img" src="">
</div>
</div>
<div class="image-thumbnails"></div>
<div>
<%= hidden_field_tag(:buy_link, "") %>
<%= hidden_field_tag(:user_id, "") %>
<%= hidden_field_tag(:pcurl, "") %>
<%= hidden_field_tag(:murl, "") %>
<%= hidden_field_tag(:gid, "") %>
<%= hidden_field_tag(:posturl, "") %>
<%= hidden_field_tag(:mainpic, "") %>
<%= hidden_field_tag(:piclist, "") %>
<%= hidden_field_tag(:website, "") %>
</div>
</div>
</div>
<div class="row">
<div class="media add-entity-note" style="display:none;">
<div class="media-body">
<fieldset>
<div class="form-group">
<div class="col-sm-offset-1 col-sm-10">
<%= text_area_tag(:recommend, "来说说你的评价吧？欢迎真实、有用、有趣的商品点评。", :rows => 4, :class => 'form-control', :name => 'recommend') %>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-9 col-sm-3">
<%= f.submit "提交", class: 'btn btn-primary', data: {disable_with: "发表..."} %>
</div>
</div>
</fieldset>
</div>
</div>
</div>
</div>
<% end %>
post 之后得到的参数是这样的
{"utf8"=>"✓", "authenticity_token"=>"6btCz9lvderZ+4Q8soQFe6bOxzuc/upD+ZAsx3dxnWKSMzp9MbhKR0tFvEI5lJOXHJ9bRMEovZCl6T+MIK7BBw==", "product"=>{"product_category_id"=>"1"}, "price"=>"53.90", "title"=>"美国aveenobaby婴儿儿童天然燕麦润肤乳宝宝面霜227g湿疹无激素", "buy_link"=>"", "user_id"=>"", "pcurl"=>"http://item.taobao.com/item.htm?id=16718391999", "murl"=>"http://h5.m.taobao.com/awp/core/detail.htm?id=16718391999", "gid"=>"", "posturl"=>"", "mainpic"=>"http://gw.alicdn.com/bao/uploaded/i3/TB1dSqxHXXXXXbGXVXXXXXXXXXX_!!0-item_pic.jpg", "piclist"=>"http://gw.alicdn.com/bao/uploaded/i3/TB1dSqxHXXXXXbGXVXXXXXXXXXX_!!0-item_pic.jpg,http://gw.alicdn.com/bao/uploaded/i4/654369049/T29vGVXy8aXXXXXXXX_!!654369049.jpg,http://gw.alicdn.com/bao/uploaded/i4/654369049/T2oUeVXDpXXXXXXXXX_!!654369049.jpg,http://gw.alicdn.com/bao/uploaded/i2/654369049/T2cryWXBJXXXXXXXXX_!!654369049.jpg", "website"=>"TB", "recommend"=>"来说说你的评价吧？欢迎真实、有用、有趣的商品点评。", "commit"=>"提交", "controller"=>"products", "action"=>"create"}
我希望得到参数是这样的
{"utf8"=>"✓", "authenticity_token"=>"6btCz9lvderZ+4Q8soQFe6bOxzuc/upD+ZAsx3dxnWKSMzp9MbhKR0tFvEI5lJOXHJ9bRMEovZCl6T+MIK7BBw==", "product"=>{"product_category_id"=>"1"}, "price"=>"53.90", "title"=>"美国aveenobaby婴儿儿童天然燕麦润肤乳宝宝面霜227g湿疹无激素", "buy_link"=>"", "user_id"=>"", "pcurl"=>"http://item.taobao.com/item.htm?id=16718391999", "murl"=>"http://h5.m.taobao.com/awp/core/detail.htm?id=16718391999", "gid"=>"", "posturl"=>"", "mainpic"=>"http://gw.alicdn.com/bao/uploaded/i3/TB1dSqxHXXXXXbGXVXXXXXXXXXX_!!0-item_pic.jpg", "piclist"=>"http://gw.alicdn.com/bao/uploaded/i3/TB1dSqxHXXXXXbGXVXXXXXXXXXX_!!0-item_pic.jpg,http://gw.alicdn.com/bao/uploaded/i4/654369049/T29vGVXy8aXXXXXXXX_!!654369049.jpg,http://gw.alicdn.com/bao/uploaded/i4/654369049/T2oUeVXDpXXXXXXXXX_!!654369049.jpg,http://gw.alicdn.com/bao/uploaded/i2/654369049/T2cryWXBJXXXXXXXXX_!!654369049.jpg", "website"=>"TB", "recommend"=>"来说说你的评价吧？欢迎真实、有用、有趣的商品点评。", "commit"=>"提交", "controller"=>"products", "action"=>"create"}
区别在
"product"=>{"product_category_id"=>"1"}, "price"=>"53.90", ..............
我希望
"product"=>{"product_category_id"=>"1" "price"=>"53.90", ..............},
<%= f.text_field :price, class: "form-control" %>
或者
<input class="form-control" type="text" name="product[price]">
两种方案
# 1
<input class="form-control" type="text" name="product['price']">
# 2
<%= f.text_field :price %>
#1 楼 @perish #2 楼 @flowerwrong
谢谢 但是 find("input[name=product[price]]").val(data.data.price); 在 jquery 里这样确实不行了
Uncaught Error: Syntax error, unrecognized expression: name=product[price]]
问题解决需要转义字符 addEntity.find("input[name=product\[price\]]").val(data.data.price);
