在html.erb文件中创建方法 [英] Create method in html.erb file

问题描述

我必须在文件 myCode.html.erb中创建一个方法。我必须用html编写ruby代码。到目前为止，我开始知道如何编写方法并按如下方式调用该方法。

I have to create one method in file say 'myCode.html.erb'. I have to write ruby code with html. So far I came to know how to write method and call that method as below.

method creation
<%def helo
    print "This is function"
end%>

<%=helo%> #calling method

但是我在如何编写必须同时写两种方法的方法上感到困惑红宝石和html代码。以下是我需要在方法中编写的代码。

But I'm in dilemma about how to write method in which I have to write both ruby and html code. Below is my code which I need to write in method.

<% 
   actions.each{ |action|
     tc = []
     bizA = []
     testcaseName = ''
     bizActionName = '' 
     @factory.testcases.rows({'steps.action._actionId' => action["_id"]}).each{|testcase|
       d = ''
       testcaseName = testcase['attributes']['name'] + d
       d = ', '
       tc << testcaseName
     }
    # require 'ruby-debug' ; debugger
     if !action['isGrouping']
     actions.each{|act|
     if act['isGrouping']
       temp = []
       temp = act['steps']
       temp.each{|step|
         if action['_id']==step['action']['_actionId']
           bizA << act['name']
         end
       }
      end 
     }
     end
%>
    <tr>
      <td><%= name %></td>
      <td><%= action['name']  %></td>
      <td><%= @factory.testcases.rows({'steps.action._actionId' => action["_id"]}).length %> </td>
      <td>
        <% counter=1%>
        <% for ix in 0..tc.length-1 %>
          <% if counter%2==0 %>
            <%if ix!=tc.length-1 %>
              <font color="black"><%= tc[ix] %></font> <br/>
            <%else%>
              <font color="black"><%= tc[ix] %></font> <br/>
            <%end%>
          <% else %>
            <%if ix!=tc.length-1 %>
              <font color="brown"><%= tc[ix] %></font> <br/>
            <%else%>
              <font color="brown"><%= tc[ix] %></font> <br/>
            <%end%>

          <%end%>
        <% counter=counter+1 end %>
      </td>
      <td><%=bizA.length%></td>
      <td>
        <% counter=1%>
        <% for ix in 0..bizA.length-1 %>
          <% if counter%2==0 %>
            <%if ix!=bizA.length-1 %>
              <font color="black"><%= bizA[ix] %></font> <br/>
            <%else%>
              <font color="black"><%= bizA[ix] %></font> <br/>
            <%end%>
          <% else %>
            <%if ix!=bizA.length-1 %>
              <font color="brown"><%= bizA[ix] %></font> <br/>
            <%else%>
              <font color="brown"><%= bizA[ix] %></font> <br/>
            <%end%>

          <%end%>
        <% counter=counter+1 end %>
      </td>  
    </tr>  
<% } %>

如果我采用上述创建的方法 helo 作为参考，并以这种方式编写此ruby + html代码，则无法正常工作。它显示语法错误。

If I take the above created method helo as a reference and write this ruby+html code in that manner, it is not working. It is showing syntax error.

推荐答案

在某些助手中定义方法

module TestHelper
  def test
    return 'Hello World'
  end
end

在HTML文件/ .erb中，您只需插入

In your HTML file / .erb, you just insert

<%= TestHelper.test %>

在您的HTML中，您会看到 Hello World

In your HTML you will see 'Hello World'
