我尝试使用GitHub的建议示例。您还可以在这样的答案中找到它,适用于Rails 4。
我已经在Rails 5.0.1中尝试过此操作,我只是在数据库中存储一个空哈希{}:
def proposal_params
params.require(:proposal).permit(:document, :account_id).tap do |whitelisted|
whitelisted[:document] = params[:proposal][:document]
end
end
显然,如果我只允许!它有效。
我还尝试了这个问题的答案:
def proposal_params
params.require(:proposal).permit(:account_id, document: Proposal.stored_attributes[:document])
end
但这也不起作用。
the:文档属性包含json,在请求之间永远都不相同...并且是一个漫长而复杂的结构。
我只需要按照JSONB列将其倾倒。
对于好奇,这是document
中可以的示例:
{
"document":{
"customer":{
"id":"273a0ad1-0867-4c17-8e0a-3284c6f2f6af",

如果我正确,您仍然需要permit!
文档参数:
def proposal_params
params.require(:proposal).permit(:account_id).tap do |whitelisted|
whitelisted[:document] = params[:proposal].fetch(:document, ActionController::Parameters.new).permit!
end
end
此工作的方法是,它仅将account_id
放在首先将其保留,但是在tap
中,我们通过尝试从原始参数检索来添加document
参数。ActionController::Parameters.new
作为fetch
的默认值确保permit!
方法即使没有传递document
参数也始终可调用。
在引擎盖ActionController::Parameters#permit!
下似乎也递归地在包含的参数上调用permit!
函数,因此我们可以在任何实例上称其为:
def permit!
each_pair do |key, value|
Array.wrap(value).each do |v|
v.permit! if v.respond_to? :permit!
end
end
@permitted = true
self
end
您可以尝试:
to_unsafe_hash
