How do I put an IF statement in a templates file in Elixir Phoenix?

<%= if appointment.rut_paciente != 0 %>
  HTML
<% end %>

Thanks! But I already tried that and it doesn’t work :c

<%= for appointment <- @appointments do %>
  <%= if appointment.rut_paciente != 0 %>
    <tr>
      <td><%= appointment.rut_paciente%></td>
      <td><%= appointment.fecha %></td>
      <td><%= appointment.id_medico %></td>
      <td><%= appointment.bloque %></td>
  <% end %>

…

<%= if appointment.rut_paciente != 0 do %>

i.e. the do is missing

Same error :c Thanks anyway

Do you have a module called Medica.AppointmentView? You should be getting a compile error if the EEx is invalid. I would add the do that peerreynders mentioned and do a mix clean, followed by a mix compile. If there’s an error you should get a compiler error.

That error usually means that you have a compilation error. You should look at the output from your Phoenix server for the details. You can also try restarting your Phoenix server since that will nicely print out any compilation errors.

Thanks! I’ll paste the compilation error:

== Compilation error in file web/views/appointment_view.ex ==

Yes, there is. And it is a compilation error, I hope we can solve this.

Paste the lines around that line in the template
