如何在rails上将本地字符串传递给ruby中的部分(How to pass a local string to a partial in ruby on rails)

 TL; DR版本的问题  
 是否有可能将字符串传递给partial，并在if语句或switch case中部分使用该字符串。  
 我是否通过让观点直接对话来打破Rails的一些有价值的规则？  
 长版本w /代码片段  
 我认为可以肯定地说，在这个时候，我读过的每一篇文章都讲述了如何传递一个局部变量。 完成此操作仍然存在问题。 我对铁轨非常陌生，例如1周的学习，所以我想要做的事情可能完全不正确。  
 无论如何，我已经设置好了，这样当用户点击导航栏上的链接时，引导模式会以正确的形式加载它。 我已经将每个独特的形式设置为自己的部分，以便我可以放在需要的地方，并且还将模态设置为部分。 我试图遵循这个DRY方法，并使其在模态部分有一个if / else或switch逻辑，它只根据链接传递的内容加载正确的表单。  
 模态部分：  
<!-- Modal -->
<div class="modal fade" id="modalTemplate" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal Template</h4>
      </div>
      <div class="modal-body">
        <% if %VARIABLE% == "%PASSED-INPUT%" %>
          <% @customer = Customer.new %>
          <%= render "customers/new" %>
        <% elsif %VARIABLE% == "%PASSED-INPUT%" %>
          --> Do something else
        <% end %>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>
 
 NavBar部分：  
<%= render 'layouts/modal_template' %>

<nav class="navbar navbar-default navbar-fixed-side">
    <h6 class="navbar-heading">Customer Management</h6>
  <div class="list-group">
    <%= link_to "Add New Customer", '#modalTemplate', 'data-toggle' => 'modal', what_to_render: "Test", class: 'list-group-item' %>
    <%= link_to "Manage Customers", '#', class: 'list-group-item' %>
    </div>
    <h6 class="navbar-section-heading">Customer Status Management</h6>
    <div class="list-group">
    <%= link_to "Add New Customer Status", new_customers_status_path, class: 'list-group-item' %>
    <%= link_to "Manage Customer Statuses", '#', class: 'list-group-item' %>
    </div>
</nav>
 
 本页主视图：  
<div class="container-fluid">
  <div class="row">
    <div class="col-sm-3 col-lg-2">
      <%= render 'layouts/side-nav' %>
    </div>
    <div class="col-sm-9 col-lg-10">
      <div class="well">
        <%= render 'test' %>
        <%= render 'view_customers' %>
      </div>
    </div>
  </div>
</div>
 
 现在，“增加新客户”link_to是给我带来最大麻烦的部分。 我尝试了在线提供的每种不同的组合，但它似乎总是基于使用对象或数据库中的某些东西的想法。 事情是，我只是试图加载一个基于所选按钮的不同页面，同时使用相同的模态部分。  
 link_to我试过的例子：  
<%= link_to "Add New Customer", '#modalTemplate', 'data-toggle' => 'modal', what_to_render: "Test", class: 'list-group-item' %>
<%= link_to "Add New Customer", '#modalTemplate', 'data-toggle' => 'modal', :locals =&t; { what_to_render: "Test" }, class: 'list-group-item' %>
 
 还有更多，但我已经删除了这么多的代码行，我已经失去了它们。 一些包括使用link_to与：partial和：locals 

TL;DR Version of Question 
Is it possible to pass a string to a partial and have the partial use that string in an if statement or switch case. 
Am I breaking some valuable rule of Rails by having the views talk directly to each other? 
Long Version w/ Code Snippets 
I think it's safe to say that at this point in time I've read every post there is about how to pass a local variable. I'm still having trouble with accomplishing this. I'm very new to rails, like.. 1 week of learning, so what I'm trying to do might be completely incorrect. 
Anyways, I have it set up so that when a user clicks a link on the navbar a bootstrap modal loads with the correct form inside of it. I've set each unique form as their own partial so that I can just drop there in where needed and I've also setup the modal as a partial. I'm trying to follow this DRY method and make it so that in the modal partial it has a if/else or switch logic that only loads the correct form based on what the link passes it. 
Modal Partial: 
<!-- Modal -->
<div class="modal fade" id="modalTemplate" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal Template</h4>
      </div>
      <div class="modal-body">
        <% if %VARIABLE% == "%PASSED-INPUT%" %>
          <% @customer = Customer.new %>
          <%= render "customers/new" %>
        <% elsif %VARIABLE% == "%PASSED-INPUT%" %>
          --> Do something else
        <% end %>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>
 
NavBar Partial: 
<%= render 'layouts/modal_template' %>

<nav class="navbar navbar-default navbar-fixed-side">
    <h6 class="navbar-heading">Customer Management</h6>
  <div class="list-group">
    <%= link_to "Add New Customer", '#modalTemplate', 'data-toggle' => 'modal', what_to_render: "Test", class: 'list-group-item' %>
    <%= link_to "Manage Customers", '#', class: 'list-group-item' %>
    </div>
    <h6 class="navbar-section-heading">Customer Status Management</h6>
    <div class="list-group">
    <%= link_to "Add New Customer Status", new_customers_status_path, class: 'list-group-item' %>
    <%= link_to "Manage Customer Statuses", '#', class: 'list-group-item' %>
    </div>
</nav>
 
The Main View for this Page: 
<div class="container-fluid">
  <div class="row">
    <div class="col-sm-3 col-lg-2">
      <%= render 'layouts/side-nav' %>
    </div>
    <div class="col-sm-9 col-lg-10">
      <div class="well">
        <%= render 'test' %>
        <%= render 'view_customers' %>
      </div>
    </div>
  </div>
</div>
 
Now, the "Added New Customer" link_to is the part that is giving me the most trouble. I've tried every different combination provided online, but it always seems to be based around the idea of working with an object or something from the database. Thing is, I'm just trying to load a different page based on the selected button all while using the same modal partial. 
link_to Examples that I've Tried: 
<%= link_to "Add New Customer", '#modalTemplate', 'data-toggle' => 'modal', what_to_render: "Test", class: 'list-group-item' %>
<%= link_to "Add New Customer", '#modalTemplate', 'data-toggle' => 'modal', :locals => { what_to_render: "Test" }, class: 'list-group-item' %>
 
There are more, but I've deleted so many lines of code at this point that I've lost them. Some included using the link_to with :partial and :locals
