Questions / Help

I want to change following HTMl code

<%= link to: Routes.job_opening_path(@conn, :index), class: "nav-link" do %>
....other div element
<% end %>

to

<%= link to: <%= if check_workspace_activation() , do: Routes.job_opening_path(@conn, :index), else: "#" %>, class: ""  do %>
...other div element
<% end %>

When I use last HTML code, I am getting following error

syntax error before: '<'

What I am missing here ? Your help will be appreciateed

As if/2 is an expression, you should be able to do something like this:

<%= link to: if check_workspace_activation() do Routes.job_opening(@conn, :index) else "#" end, class: "" do %>
  <!-- more stuff -->
<% end %>

Following I wrote

 <%= link to: if check_workspace_activation() do Routes.job_opening(@conn, :index) else "#" end, class: "nav-link" do %>

Still, getting following error

syntax error before: ','

Then we probably need the ugly parenthesized version of the if/2, but I can’t test right now, as I have no project in reach that would have EEx:

<%= link to: if(check_workspace_activation(), do: Routes.job_opening(@conn, :index), else: "#"), class: "" do %>
  <!-- … -->
<% end %>

But perhaps using a helper is the better strategy?

Could you explain more, this new strategy you are talking about?

The strategy is to put parenthesis around if…

By the way, You could also write a helper function inside the view.

This is exactly the strategy I’m talking about.

Yes, view files should contain helper functions in order to simplify templates…
