ruby-on-rails - f.check_box checked => true for ruby on rails

Question

Hi I have the following code on my view:

//I write a loop here to display some workflows saying wkf.each do |i|
<% if (i write my condition here) %>
  <td style="text-align:left;">
  <%= f.check_box :i, {:checked=>true}%> 
  <%= f.label(i, i)%>
  </td></tr>
<% else %>
  <td style="text-align:left;">
  <%= f.check_box(i)%> 
  <%= f.label(i, i)%>
  </td></tr>
<%end%>

Suppose that there are three workflows 'A', 'B' and 'C' and 'C' meets the if condition, then the parameters being sent are 'A'=>0, 'B'=>0 and 'i'=>'1'. I want it to be sent as 'C'=>'1' in the same way as 'A'=>0.

I know that 'i' =>'1' is sent because i wrote f.check_box :i, {:checked=>true}% instead of <%= f.check_box(i)%>.

Please let me know how to change this so that, the check box is checked by default when the if condition is met and the #{i} would be sent instead of :i

Thanks

Answer 1

thef.check_box :i不等于f.check_box(i)，区别在于i是变量，while:i是符号，和字符串差不多。:在第一种情况下删除。

<%= f.check_box i, {:checked=>true} %>
