我正在试图弄清楚为什么我的Rails应用程序不允许我的属性,并且已经没有什么想法了。
我的数据库中有产品(型号Product),它们有一组适用于所有产品的标准属性。我有一个额外的JSONB列,称为dynamic_attributes,它特定于不同类型的产品。因此,我目前使用STI。
如果我试图编辑一个单独的记录,我会得到一个关于不允许的参数(我试图从编辑表单更新/修补的JSON参数)的错误。如果我删除.permit部分并只允许!everywhere,那么我不会得到任何错误,所有内容都会更新,但显然这并不理想。
STI的锁子类
class Lock < Product
serialize :dynamic_attributes, JsonbSerializers
store_accessor :dynamic_attributes, :kind, :interface
validates :kind, presence: true
def json_schema
Rails.root.join('app', 'models', 'schemas', 'lock_category.json')
end
end
它为所讨论的产品类型引用以下JSON模式:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"required": [ "kind" ],
"properties": {
"kind": {
"type": "string",
"enum": ["Cable", "Chain", "Folding", "Frame", "Part", "Padlock", "U-Lock", "U-Lock+Cable"]
},
"interface": {
"type": "string",
"enum": ["Key", "Combination", "Smart"]
}
}
}
产品控制器
def update
@product = Product.find(params[:id])
@product.update!(product_params)
redirect_to @product
end
private
def product_params
params.require(:product).
permit(
:type,
:vendor,
:description,
:cost,
:msrp,
dynamic_attributes: [
:kind,
:interface
]
)
end
end
编辑表单是非常标准的,包含以下用于更新dynamic_attributes的部分:
<% @product[:dynamic_attributes].each do |k,v| %>
<%= f.label k.to_sym %>
<%= f.text_field k.to_sym, :value => v %>
<br />
<% end %>
如果让我猜测(此时我所剩下的,我认为它可能是从数据库加载信息到编辑字段,然后再返回之间的事情。
尝试修补程序的日志:

感谢@engineersmnky,他给出了答案:
kind和interface是不允许的,因为您声明它们应该嵌套在dynamic_attributes下,但在请求中它们没有嵌套。也许可以尝试更改此设置
因此,我相应地更新了代码:
