如何创建选择字段?
请帮助解决问题。
有表性别:
CREATE TABLE "genders" ("id"
INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, "gender_name"
varchar, "created_at"
datetime NOT NULL, "updated_at"
datetime NOT NULL)
有一个表用户:
CREATE TABLE "users" ("id"
INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, "name"
varchar, "email"
varchar, "password_digest"
varchar, "remember_token"
varchar, "phone"
varchar, "skype"
varchar, "info"
varchar, "gender_id"
integer DEFAULT 1, "created_at"
datetime NOT NULL, "updated_at"
datetime NOT NULL, "diary_name"
varchar, "views_diary"
integer DEFAULT 0, "admin"
boolean DEFAULT 'f')
在模特'用户':
GENDER_TYPES = [['Lisbon', 1], ['Madrid', 2]]
在视图' new.html.erb':
<%= form_for(@user) do |f| %>
<div>
<%= f.label :name %>
<%= f.text_field :name %>
</div>
<div>
<%= f.label :gender %>
<%= f.select :gender, User::GENDER_TYPES %>
</div>
<% end %>
但它不起作用。问题是,表单提交值未记录在&users; users.gender_id&#39;
之后答案 0 :(得分:1)
您的选择应该是设置gender_id
,而不是gender
:
<%= f.select :gender_id, User::GENDER_TYPES %>
