How to use hidden field tag in rails

Question

Say I have this form, but already have a variable, client_id, that I want to pass to the controller. It looks like I need to use a hidden_field_tag. I tried it but I don't think my syntax is quite right. Any idea what i'm doing wrong? Thanks

<%= form_for(@assessment) do |f| %>
  <div class="field">
    <%= f.label :weight %><br>
    <%= f.text_field :weight %>
  </div>
  <div class="field">
    <%= f.label :heartrate %><br>
    <%= f.text_field :heartrate %>
  </div>
  <div class="field">
    <%= f.label :bodyfat %><br>
    <%= f.text_field :bodyfat %>
  </div>

    <%= hidden_field_tag :client_id, @client.id %>

  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

where you are setting @client object? and how?

Please refer following links hidden_field or hidden_field_tag

        <%= f.hidden_field :client_id, 1 %>
        <%= hidden_field_tag 'client_id', '1'  %>

Note when you used

   <%= f.hidden_field :client_id, 1 %>

it change to html

<input type="hidden" id="request_client_id" name="request[client_id]" value="1" />

and when you used

<%= hidden_field_tag 'client_id', '1'  %>

it change to html

   <input id="client_id" name="client_id" type="hidden" value="1"/>

So, I think here you should use <%= f.hidden_field :client_id, @client.id %>

Hope it will work for you.

Try doing:

<%= f.hidden_field :client_id, value: @assessment.client_id %>

Since, as in your prior question, you are setting @assessment.client_id in your new action.

You should use:

<%= f.hidden_field :client_id, value: @client.id %>

Should the client_id be part of the assessment_params? If so, you can attach it to the form object, i.e. <%= f.hidden_field :client_id, value: @client.id.

Otherwise I think your tag should pass through, just outside of the assessment params hash.
