我有看法:
<%= form_tag mined_materials_url do %>
<%= render 'import_fields' %><br />
<%= render 'import_fields' %>
<%= button_tag :submit %>
<% end %>
_import_fields.html.erb:
<%= text_field_tag 'mined_material[][character_id]','' %>
<%= text_field_tag 'mined_material[][material_id]','' %>
<%= text_field_tag 'mined_material[][quantity]','' %>
<%= text_field_tag 'mined_material[][price]','' %>
(我将通过 JS 添加更多字段)
并且需要一次将多条记录插入到同一模型中,但由于错误而无法保存:未定义的方法`permit' for Array:0x00000001f63230
参数:
{"utf8"=>"✓",
"authenticity_token"=>"fFR3nWwz2Q0ivED6XXyj4ICRBtj5Rdois4N++cNnCko=",
"mined_material"=>[{"character_id"=>"1",
"material_id"=>"1",
"quantity"=>"1",
"price"=>"1"},
{"character_id"=>"2",
"material_id"=>"2",
"quantity"=>"2",
"price"=>"2"}],
"button"=>""}
我怎么能允许批量创建?
