Rails doesn't render partial like it says it has

My rails server says that it has rendered my partial in my page, but the content is not there. Even when I inspect the elements on the page using Chrome DevTools, the div that is supposed to be rendered isn't there.

EDIT: Fixed that problem, but now the partial inside that partial won't render. I'll opena new question for that problem.

show.html.erb (with fix):

<% provide(:title, @user.name) %>
<% provide(:pagetitle, @user.name) %>

<% render'layouts/relation' unless current_user?(@user)%>

<div id="stats">
    Player Statistics will appear here.
</div>

<div id="characters">
    Player Characters will appear here.
</div>

_relation.html.erb (the partial):

<div id="relation">
    <% if current_user.friends?(@user) %>
        <%= render 'layouts/edit_relation', locals: { action: "rm-friend" } %>
    <% elsif current_user.req_friends?(@user) %>
        Friend Request Pending...
    <% elsif current_user.pend_friends?(@user) %>
        <%= render 'layouts/edit_relation', locals: { action: "add-friend" } %>
        <%= render 'layouts/edit_relation', locals: { action: "rej-friend" } %>
    <% else %>
        <%= render 'layouts/edit_relation', locals: { action: "req-friend" } %>
    <% end %>
</div>

_edit_relation.html.erb (the partial within the partial):

<% case :action %>
    <% when "req-friend"%>
        <%= form_for(current_user.relation.build(character: @user.id, type: "freq"), remote: true) do |f| %>
            <div><%= f.hidden_field :character %></div>
            <div><%= f.hidden_field :type %></div>
            <%= f.submit "Add Friend", class: "btn btn-large btn-primary" %>
        <% end %>

    <% when "add-friend"%>
        <%= form_for(current_user.relation.build(character: @user.id, type: "friend"), remote: true) do |f| %>
            <div><%= f.hidden_field :character %></div>
            <div><%= f.hidden_field :type %></div>
            <%= f.submit "Accept Request", class: "submit" %>
        <% end %>

    <% when "rej-friend" %>
        <%= form_for(current_user.reverse_relation.find_by(owner: @user.id, type: "freq"), html: { method: :delete }, remote: true) do |f| %>
            <%= f.submit "Reject Request", class: "submit" %>
        <% end %>

    <% when "rm-friend"%>
        <%= form_for(current_user.reverse_relation.find_by(owner: @user.id, type: "friend"), html: { method: :delete }, remote: true) do |f| %>
            <%= f.submit "Remove Friend", class: "submit" %>
        <% end %>

<% end %>

My server log that says that the partial has been rendered:

You're missing an = here--

<%= render 'layouts/relation' unless current_user?(@user) %>

Calling render will still generate the string, which is why you are seeing it in your logs; without the equals sign it's not going to appear on the page.

So from your layouts/relation partial you're rendering another partial (layouts/edit_relation), right? Maybe that's where the problem is.

You need to use the rendering ERB tag:

<%= render 'layouts/relation' unless current_user?(@user) %>
