我想使用单个更新按钮在单个视图中使用批量更新每个操作。使用以下代码,Rails 会抛出此错误
Showing /home/vincent/git/gestion/app/views/operations/tag.html.erb where line #23 raised:
undefined method `merge' for 1:Fixnum
Extracted source (around line #23):
20: <td>
21: <% @tags.each do |elem| %>
22: <%= f.label elem.tag %>
23: <%= f.check_box "operation[tag_ids][]", elem.id, operation.tags.include?(elem) %>
24: <% end %>
25: </td>
26: <td><%= f.submit %></td>
楷模
class Operation < ActiveRecord::Base
attr_accessible :credit, :date_operation, :debit, :libelle, :tag_ids
has_and_belongs_to_many :tags
accepts_nested_attributes_for :tags, :allow_destroy=>true
end
class Tag < ActiveRecord::Base
attr_accessible :id, :tag
has_and_belongs_to_many :operations
end
控制器
def tag
@operations = Operation.limit(100)
@tags = Tag.all
respond_to do |format|
format.html { "tag" }# tag.html.erb
# format.json { render json: @operations }
end
end
看法
<% @operations.each do |operation| %>
<tr>
<td><%= operation.date_operation %></td>
<td><%= operation.libelle %></td>
<td><%= operation.credit %></td>
<td><%= operation.debit %></td>
<%= form_for operation do |f| %>
<td>
<% @tags.each do |elem| %>
<%= f.label elem.tag %>
<%= f.check_box "operation[tag_ids][]", elem.id, operation.tags.include?(elem) %>
<% end %>
</td>
<td><%= f.submit %></td>
<% end %>
</tr>
<% end %>
你对这个问题有任何线索/帮助吗?
先感谢您
