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> <%= f.label :weight %><br> <%= f.text_field :weight %> </div> <div> <%= f.label :heartrate %><br> <%= f.text_field :heartrate %> </div> <div> <%= f.label :bodyfat %><br> <%= f.text_field :bodyfat %> </div> <%= hidden_field_tag :client_id, @client.id %> <div> <%= f.submit %> </div>

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" name="request[client_id]" value="1" />and when you used
<%= hidden_field_tag 'client_id', '1' %>it change to html
<input 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 %>Some source:
<%= f.hidden_field :client_id, :value => @assessment.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.
