How to save data using Redmine issue model

Question

I need to modify the issue's start_date and due_date some how,

But I haven't used Rails before, so I don't know how the it run in server, And I need to implement it in a short time.

So I add these code in the controller,

  def date
    issue = Issue.find(params[:id])
    issue.start_date = params[:start_date]
    issue.due_date = params[:due_date]
    ntc_str = "Fail to save!" + params[:id]
    if issue.save
       ntc_str = 'Issue saved!'
    end
    flash[:notice] = ntc_str;
    redirect_to :controller => 'gantts', :action => 'show', :project_id => params[:p_id]
  end

It runs when I access it by myself It always failed and the "ntc_str" always is "Fail to save!" if I use javascript to access it.

For example: It runs when I input the url "http://xxx.xxx.xxx.xxx/date?id=6&project_id=test&start_date=2016-06-08&due_date=2016-06-30" by hands, But it failed when I use javascript "window.location.href='/date?id=6&project_id=test&start_date=2016-06-08&due_date=2016-06-30'"

It runs when I input the params in the form I create and click to submit it, But it failed when I use javascript "document.getElementById('start_date').value = '2016-06-30'; /..../ $('#test-form').submit()"

Could you tell me why it always fails and how can I use the issue model? I have be crazy now.

It would be useful, if you provide some logs with each cases you try.

Also, you can see what goes wrong with issue, when you try to save it, with:

if issue.save
   ntc_str = 'Issue saved!'
else 
   Rails.logger.error(issue.errors.full_messages)
end
