无法在用户模型上设置新属性(使用 Devise & Rails 5)

Question

我在我的用户模型（Devise）中添加了一个新的属性/列（locale）。我将使用它来保存用户选择的语言以显示应用程序。这是由用户在默认的设计注册表单上选择的。

我已将 devise_parameter_sanitizer 方法添加到我的应用程序控制器以允许新参数，但每次添加新用户时，数据库中的locale列始终为空。

如果我按照日志进行操作，我可以看到参数已传递到创建操作，但由于某种原因，它在中间的某个地方丢失了。

希望得到一些关于我在这里做错了什么的指导。

创建新用户时记录

        unless params[:controller] == 'devise/sessions' || params[:access_token].present? # TODO this is a potential security gap - patch this up so that it can't just any old token, it must be a valid one (look in the captables controller)
        @current_user_companies = current_user.companies unless !user_signed_in?
        if !params[:company_id].present?
            @company = Company.find(params[:id]) unless !params[:id].present?
        else
            @company = Company.find(params[:company_id]) unless !params[:company_id].present?
        end
        unless !@company
            if !@current_user_companies.include?(Company.find(@company.id))
            redirect_to companies_path, alert: "Access denied: You do not belong to this company"
            end
        end
        end
    end
    protected
    def configure_permitted_parameters
        # Permit some additional params on the user sign up that aren't the default email, password etc
        devise_parameter_sanitizer.permit(:sign_up, keys: [:locale])
    end
end

我的注册表格

    <%= devise_error_messages! %>
    <div class="field">
        <%= f.label :email %><br />
        <%= f.email_field :email, autofocus: true, autocomplete: "email" %>

        <% if @minimum_password_length %>
        <em>(<%= @minimum_password_length %> characters minimum)</em>
        <% end %><br />
        <%= f.password_field :password, autocomplete: "new-password" %>
    </div>
    <div class="field">

Answer 1

试试这个！

改变

 <%= select_tag(:locale, options_for_select([["English", "en"], ["Swedish", "sv"]])) %>

自

 <%= f.select :locale, options_for_select([["English","en"],["Swedish","sv"]]), {include_blank: "locale"} %>

Answer 2

如果您检查日志，您会发现您的locale参数不在user范围内。我重新格式化了这一行：

    Parameters: {
      "utf8"=>"✓",
      "authenticity_token"=>"...", 
      "user"=>{
         "email"=>"[e-mail]", 
         "password"=>"[FILTERED]", 
         "password_confirmation"=>"[FILTERED]"
      }, 
      "locale"=>"sv", 
      "commit"=>"Sign up"
}

因此，您应该将其添加到user参数组中。

据我了解，发生这种情况是因为您没有将其绑定到表单上。您应该在表单中使用f.select而不是select_tag。
