我有以下简单形式:div class = fieldWithError去哪了?
<% form_for(@weight) do |f| %>
<%= f.error_messages %>
<%= f.label :weight %>:
<%= f.text_field :weight, :size => 5 %> kg.
<%= f.submit "Add weight" %>
<%= f.error_message_on :weight %>
<% end %>
仅显示一个场的形式:重量。
通常它呈现这样的:
<form action="/weights" class="new_weight" id="new_weight" method="post">
<div style="margin:0;padding:0;display:inline"><input name="authenticity_token" type="hidden" value="jYoVJkDnv4a1DMGnelJpGPElbH0XWKPNlESTt9GvzdA=" /></div>
<label for="weight_weight">Weight</label>:
<input id="weight_weight" name="weight[weight]" size="5" type="text" /> kg.
<input id="weight_submit" name="commit" type="submit" value="Add weight" />
</form>
这是罚款。当我提交此表单而未设定任何重量时,我收到验证错误。 f.error_messages和f.error_messages_on:权重正确显示错误消息,但标签和文本字段未包含在类fieldWithError的div中,正如我通常在Rails中的表单中所期望的那样。我反而得到这样的:
<form action="/weights" class="new_weight" id="new_weight" method="post">
<div style="margin:0;padding:0;display:inline"><input name="authenticity_token" type="hidden" value="jYoVJkDnv4a1DMGnelJpGPElbH0XWKPNlESTt9GvzdA=" /></div>
<div class="errorExplanation" id="errorExplanation">
<h2>1 error prohibited this weight from being saved</h2>
<p>There were problems with the following fields:</p>
<ul><li>Weight can't be blank</li></ul>
</div>
<label for="weight_weight">Weight</label>:
<input id="weight_weight" name="weight[weight]" size="5" type="text" /> kg.
<input id="weight_submit" name="commit" type="submit" value="Add weight" />
<div class="formError">can't be blank</div>
</form>
仅供参考,我所应该得到的是:
<form action="/weights" class="new_weight" id="new_weight" method="post">
<div style="margin:0;padding:0;display:inline"><input name="authenticity_token" type="hidden" value="jYoVJkDnv4a1DMGnelJpGPElbH0XWKPNlESTt9GvzdA=" /></div>
<div class="errorExplanation" id="errorExplanation">
<h2>1 error prohibited this weight from being saved</h2>
<p>There were problems with the following fields:</p>
<ul><li>Weight can't be blank</li></ul>
</div>
<div class="fieldWithErrors"><label for="weight_weight">Weight</label></div>:
<div class="fieldWithErrors"><input id="weight_weight" name="weight[weight]" size="5" type="text" /></div> kg.
<input id="weight_submit" name="commit" type="submit" value="Add weight" />
<div class="formError">can't be blank</div>
</form>
任何想法,为什么我不明白这些div?我安装了formtastic,并以其他形式使用,但据我所知,不应该干扰这种形式。
更新:只是为了保险起见,我打印出来的调试(@weight),它有错误:
--- &id002 !ruby/object:Weight attributes: created_at: updated_at: weight: measured_on: &id001 !timestamp at: "2009-11-22 01:30:13.522589 +01:00" "@marshal_with_utc_coercion": false user_id: 1 attributes_cache: measured_on: *id001 changed_attributes: measured_on: user_id: errors: !ruby/object:ActiveRecord::Errors base: *id002 errors: weight: - !ruby/object:ActiveRecord::Error attribute: :weight base: *id002 message: :blank options: {} type: :blank new_record: true
更新:该模型是
class Weight < ActiveRecord::Base
belongs_to :user
validates_presence_of :weight, :measured_on
attr_accessible :weight, :measured_on
def after_initialize
self.measured_on ||= Time.now
end
末
注:我删除了formtastic,它开始正常工作。 – Pablo 2009-11-22 00:45:40
