Why does adding a file field to my form cause “can't verify CSRF token…”












0















I have (probably) a simple problem that I can't seem to wrap my head around.



I have a simple form to edit a tenant object in my rails application. It works as expected.



However, when I add the <%= f.file_field :logo %> line into my form, I get the Can't verify CSRF token authenticity. error.



My question:
Why does adding the file_field result in this CSRF error?



The form in question:



....
<%= form_for(tenant,:html=>{:id=>"your_form_id",:multipart => true,:remote=>true}) do |f| %>
<%= render 'errors/form_errors', object: @tenant %>

<div id="login-form">
<div class="field">
<%= f.text_field :name, placeholder: "name" %>
</div>
</br>
<div class="field">
<%= f.email_field :email, placeholder: "email" %>
</div>
</br>
<div class="field">
<%= f.phone_field :phone, id: "phoneNumber", placeholder: "(XXX) XXX-XXXX", onkeypress:"return numberPressed(event);" %>
</div>
</br>

<div class="field">
<%= f.file_field :logo %> //WORKS FINE WITHOUT THIS FIELD!
</div>

<div class="actions">
<%= f.submit id: "login-button", class: "btn-outline-primary", value: "Save",'data-disable-with':"Wait..." %>
</div>
</div>

<% end %>
....


additionally, here is the code that brings up the form. Not sure if it has any relevance.



This is the code in the file that brings up my form: edit.js.erb



closeLightbox();
$("body").prepend('<%= escape_javascript(render 'edit', tenant: @tenant) %>');


EDIT: I have found a solution, although I don't really understand why it is necessary. See answer below.
