Question

我知道这已被多次询问，但由于某些原因，其他解决方案都没有对我有用。我仍然无法在更新时保存带枚举的字段。当我使用相同的表单传递非枚举值（如first_name）时，它会更新，但枚举值（性别）永远不会保存，即使它显示它是......

查看：

<%= form_for(@patient, url: patient_path(params[:id])) do |f| %>
    <%= f.fields_for :role do |r| %>
        <%= r.fields_for :user do |u| %>
        <div class="keyvalue">
            <div class="key"><p>Gender</p></div>
            <div class="value">
                <%= u.select :gender, User.genders.map { |key, value| [key.humanize, key] }, include_blank: '-Select A Gender-' %>
            </div>
            <div class="push"></div>
        </div><!--keyvalue-->
        <% end %>
    <% end %>
<% end %>

控制器：

def update
    @patient = Patient.find(params[:id])
    if @patient.update(patient_params)
        flash[:success] = "Patient's record has been updated."
        redirect_to patient_path(params[:id])
    else
        flash[:error] = @patient.errors.full_messages.to_sentence
        redirect_to patient_path(params[:id])
    end
end

用户模型中的枚举：

enum gender: [:male, :female, :non_binary, :rather_not_say]

迁移：

t.integer :gender

日志显示没有问题，它显示正在更新的性别字段，但如果我转到rails控制台，则会将性别显示为nil

Rails 5枚举，选择字段不保存
