Rails-质量分配错误的Accepts_nested_attributes_ [英] Rails - Accepts_nested_attributes_for mass assignment error
问题描述
我目前正在尝试建立一个表单,该表单的上一个居所关系上有嵌套字段,但是我遇到了批量分配错误.到目前为止,我的代码如下(已删除一些html):
I am currently trying to set up a form with nested fields on a belongs_to relationship, but I am running into a mass assignment error. My code so far is as follows (some html removed):
销售模式:
class Sale < ActiveRecord::Base
attr_accessible :customer_attributes
belongs_to :customer
accepts_nested_attributes_for :customer
end
new.html.erb:
new.html.erb:
<div class="container">
<%= form_for :sale, :url => sales_path do |sale| -%>
<%= sale.fields_for :customer do |customer_builder| %>
<%= render :partial => "customers/form", :locals => {:customer => customer_builder, :form_actions_visible => false} %>
<% end -%>
<% end -%>
customers/_form.html.erb
customers/_form.html.erb
<fieldset>
<label class="control-label">Customer Type</label>
<%= collection_select(:customer, :customer_type_id, CustomerType.all, :id, :value, {}, {:class => "chzn-select"}) %>
</fieldset>
我认为这应该允许我创建一个Sale对象和一个嵌套的Customer对象.发送的参数是(请注意包括一些不相关的参数):
I believe this should allow me to create a Sale object, and a nested Customer object. The parameters being sent are (note some unrelated params are included):
{"utf8"=>"✓",
"authenticity_token"=>"qCjHoU9lO8VS060dXFHak+OMoE/GkTMZckO0c5SZLUU=",
"customer"=>{"customer_type_id"=>"1"},
"sale"=>{"customer"=>{"features_attributes"=>{"feature_type_id"=>"1",
"value"=>"jimmy"}}},
"vehicle"=>{"trim_id"=>"1",
"model_year_id"=>"1"}}
我得到的错误是:
Can't mass-assign protected attributes: customer
我可以理解为什么会这样,因为:customer不在attr_accessible列表中出售-尽管表单不应该发送customer_attributes而不是Customer吗?
I can see why this might be the case, since :customer is not in the attr_accessible list for Sale - though shouldn't the form be sending customer_attributes instead of customer?
任何帮助/建议都值得赞赏.
Any help / advice appreciated.
据我所知,Sale模型中的attr_accessible应该包含:customer_attributes-如果有人说不同,请告诉我.
EDIT 1: As far as I can tell, attr_accessible in the Sale model should be covered with :customer_attributes - if anyone says different, please let me know.
我尝试了各种排列,但是我似乎无法获得发送customer_attributes的参数,而不是简单地发送客户-也许我错过了标签或在上面的表格中的某处使用了不正确的标签?
EDIT 2: I have tried various permutations, but I can not seem to get the parameters to send customer_attributes instead of simply customer - perhaps I have missed a tag or used an incorrect tag somewhere in the forms above?
我在SO上发现了另一个问题,该问题表明form_for标记中的:url =>
部分存在问题-该问题是指格式化设置,但我想知道这是否是导致该问题的原因.这里有问题吗?
EDIT 3: I have found another question on SO that indicated a problem with the :url =>
part on the form_for tag - the question was referring to a formtastic setup, but I'm wondering if that could be what is causing the problem here?
推荐答案
我最终在这里得到了答案.关键是这一行:
I got to the answer here eventually. The key was this line:
<%= collection_select(:customer, :customer_type_id, CustomerType.all, :id, :value, {}, {:class => "chzn-select"}) %>
需要更改为:
<%= customer.collection_select(:customer_type_id, CustomerType.all, :id, :value, {}, {:class => "chzn-select"}) %>
一旦改变了,一切就到位了.
Once this was changed, everything fell into place.
