我有点像Rails的新手。我正在写一个couchrest-rails应用程序,所以我没有使用activerecord这个模型。我只是想通了那就意味着
form_for(@model)
不行。我正在尝试研究如何使用form_tag - 但大多数示例都不涉及new和create操作。
这是错的:
<h1>New article</h1>
<% form_tag new_article_url(@article), :method => :post do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :title %><br />
<%= f.text_field :title %>
</p>
<p>
<%= f.submit 'Create' %>
</p>
<% end %>
<%= link_to 'Back', articles_path %>
因为当我运行我的Cucumber场景时,我得到了这个:
Scenario: Create Valid Article # features/article.feature:16
Given I have no articles # features/step_definitions /article_steps.rb:8
And I am on the list of articles # features/step_definitions/webrat_steps.rb:6
/home/deploy/www/www.trackingplace.com/app/ccc/app/views/articles/new.html.erb:3: warning: multiple values for a block parameter (0 for 1)
from /usr/local/lib/ruby/gems/1.8/gems/actionpack-2.3.3/lib/action_view/helpers/capture_helper.rb:36
When I follow "New Article" # features/step_definitions/webrat_steps.rb:18
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.error_messages (ActionView::TemplateError)
features/article.feature:19:in `When I follow "New Article"'
但我不明白错误,或如何解决它。
