轨道4 simple_form belongs_to的关联未定义的方法错误 [英] rails 4 simple_form belongs_to association undefined method error
问题描述
从对象文件::文件使用Rails 4,当我想呈现的一种形式(与simple_form)我有这样的错误:未定义的方法document_type_id的#<文件::文件:0x007fada4a50240>
Using rails 4, when I want to render a form (with simple_form) from an object Document::Document I have this error: undefined method document_type_id for #<Document::Document:0x007fada4a50240>
下面我的模型的一部分:
Here a part of my model:
class Document::Document < ActiveRecord::Base
...
belongs_to :document_type, -> {include(:translations)}, :class_name => 'Document::Type'
...
end
该方法新我控制器:
The method new of my controller:
def new
@document = Document::Document.new
end
和与simple_form形式的一部分:
And a part of the form with simple_form:
=f.association :document_type, prompt: t('document.documents.form.choose_document_type'), collection: Document::Type.includes(:translations)
错误:
undefined method `document_type_id' for #<Document::Document:0x007fada4a50240>
Extracted source (around line #14):
11 .row
12 =f.input :language, collection: languages_list, prompt: t("document.documents.form.choose_language"), label_html: tooltip(t('document.documents.forms.tooltips.language')), wrapper_html: {class: 'columns large-4'}, input_html: {class: 's2'}
13 =f.input :study_level, prompt: t('document.documents.form.choose_study_level'), label_html: tooltip(t('document.documents.forms.tooltips.study_level')), wrapper_html: {class: 'columns large-4'}, input_html: {class: 's2'}
14 =f.association :document_type, prompt: t('document.documents.form.choose_document_type'), collection: Document::Type.includes(:translations), label_html: tooltip(t('document.documents.forms.tooltips.type')), wrapper_html: {class: 'columns large-4'}, input_html: {class: 's2'}
15 -#=f.association :domains, collection: Domain.includes(:translations).order('name ASC'), label_html: tooltip(t('document.documents.forms.tooltips.domains')), input_html: {class: 's2'}
16 .form-actions
17 =f.button :submit, t('document.documents.form.submit')
为什么这个错误?
Why this error ?
我从轨3.2升级。之前一切都很正常。
I upgraded from rails 3.2. Before everything works great.
在轨3.2我补充说:
attr_accessible :document_type_id, ...
也许错误是从那里来了
Maybe the error is coming from there
推荐答案
抱歉不便。
这是一个问题的迁移。别人改变了迁移文件和现场 document_type_id
没了present在数据库中的表。
It was an issue with migration. Someone else changed the migration file and the field document_type_id
was no more present in the table of the database.
我花了一段时间,直到我发现这个愚蠢的问题。
It took me a while until I find this stupid issue.
感谢您的答复,并表示歉意。
