Rails pass predefined id to text_field

In my Rails 5 app I want to have already filed text_field_tag by current_login.user.full_name. Additionally I want to pass current_login.user.id inside this text_field as params[:physician_id]. What I did is pretty simple:

<%= text_field_tag "physician_id", current_login.user.id, class: 'form-control', value: current_login.user.full_name, disabled: true %>

With this code I've got:

pry> params['physician_id']
=> nil

If I add <%= text_field_tag "physician_id", id: current_login.user.id (...) I've got:

pry> params['physician_id']
=> {:id=>70, :class=>\"form-control\", :value=>\"Gary KZM JohnsonR\", :disabled=>true}

How to pass this current_login.user.id as a params['physician_id'] inside text_field_tag? should I use something else?

CodePudding user response：

For reference, the method signature is

text_field_tag(name, value = nil, options = {})

You cannot have both current_login.user.id and value: specified, they both map to value attribute of the input. Also your input is disabled so it is not being submitted with the form.

<%= text_field_tag "physician_id", current_login.user.id, class: "form-control", 
  value: current_login.user.full_name, disabled: true %>

Either you're looking for a select_field_tag or have separate physician_name input and a physician_id as hidden input

<%= text_field_tag "physician_name", current_login.user.full_name, class: "form-control" %>
<%= hidden_field_tag "physician_id", current_login.user.id, class: "form-control" %>

This will submit as params

{"physician_id"=>"1", "physician_name"=>"name"}

However I suggest you don't do that, as this is not a secure way to deal with current_user attributes. I could submit any id as physician_id and probably get access to records that don't belong to me. You should assign these attributes inside of your controller instead.
