Hi, there
Goal:
can someone help me figure out why the field :gender can not save into database ?
- when I look into database, the :user_profile field it is still the default %{}. However, the user can be registered successfully and redirect to homepage.
Context:
the simple_form of user_registration_live.ex file
<.simple_form
:let={f}
id="registration_form"
for={@changeset}
phx-submit="save"
phx-change="validate"
phx-trigger-action={@trigger_submit}
action={~p"/users/log_in?_action=registered"}
method="post"
as={:user}
>
<.error :if={@changeset.action == :insert}>
Oops, something went wrong! Please check the errors below.
</.error>
<.input field={{f, :email}} type="email" label="Email" required />
<.input field={{f, :password}} type="password" label="Password" required />
<.input field={{f, :username}} type="text" label="Username" required />
<.input
field={{f, :user_profile}}
name="user_profile[gender]"
type="select"
label="Gender"
options={["Female", "Male"]}
required
/>
<:actions>
<.button phx-disable-with="Creating account..." class="w-full">Create an account</.button>
</:actions>
</.simple_form>
