Redmine

Hello,

I am integrating Redmine with other PHP based website via JSON API. I have problem with sending date into custom field when creating new issue. I have no idea, what date format it accepts or if it even works.

I have found this validation code in app/models/custom_field.rb:

errs << ::I18n.t('activerecord.errors.messages.not_a_date') unless value.to_s =~ /^\d{4}-\d{2}-\d{2}$/ && begin; value.to_date; rescue; false end

For example '2012-05-06', which matches that regexp, doesn't work. I have tested regexp in irb, and it doesn't work with Date class. If I do value.to_s =~ /.../, then the it passes validation. But then I get another error:

ActionView::TemplateError (undefined method `empty?' for Sun, 06 May 2012:Date) on line #10 of app/views/mailer/_issue.text.erb:
7: <%=l(:field_assigned_to)%>: <%= issue.assigned_to %>
8: <%=l(:field_category)%>: <%= issue.category %>
9: <%=l(:field_fixed_version)%>: <%= issue.fixed_version %>
10: <% issue.custom_field_values.each do |c| %><%= c.custom_field.name %>: <%= show_value(c) %>
11: <% end %>
12:
13: <%= issue.description %>

    app/controllers/issues_controller.rb:162:in `create'

Not sure what now... Implement empty? for Date class and see what's next error? Am I doing something wrong? Adding issue through web interface works.

I am using redmine 1.4.3 with some minor not related modifications.

Thanks

Edit:
I can create new issue with filled Date custom field with this:

  <?xml version="1.0"?>
  <issue>
    <subject>Example</subject>
    <project_id>4</project_id>
    <tracker_id>12</tracker_id>
  <custom_fields type="array">
    <custom_field id="17">
      <value>2012-05-06</value>
    </custom_field>
  </custom_fields>
  </issue>
