gsub in cached partial-CodePudding

I have a cached partial in app/views/people:

<% cache key do %>
    <tr>
      <td>
        <%= dynamic_value %>

Is there a way, inside the view itself to do something like:

<% temp = cache key do %>
    <tr>
      <td>
        <%= dynamic_value %>

...

<%= temp.gsub("Smith","Jones") %>

The idea is to encache a slightly expensive dynamic render with placeholder text, then gsub it with dynamic values inside the partial.

Is this possible?

Thanks, Kevin

CodePudding user response：

capture helper is used for grabbing parts of the template https://api.rubyonrails.org/v7.0.2.3/classes/ActionView/Helpers/CaptureHelper.html#method-i-capture

If there is no way to only cache the expensive bit and then add user name. Any part of the template can be rendered and captured into a variable, if you modify it later it needs to be marked as html safe.

<% temp = capture do %>
  <% cache key do %>
    <%= dynamic_value %>
  <% end %>
<% end %>

<%= temp.gsub("Smith","Jones").html_safe %>
